Mazda 3 i-stop, 2010

Mazda 3 i-stop, 2010

 
 

The one way Mazda achieved this is to develop unique idle-stop technology that shuts down the engine when stopped in traffic jams and similar situations as a way to reduce fuel consumption.

The Mazda 3 will be powered by the MZR 2.0L DISI engine with green idle-stop technology - Mazda's unique i-stop system. Developed solely by Mazda, it is the world's only idle-stop system that restarts the engine using the remaining energy in the pistons (with a quick help of the starter motor) by injecting fuel directly into the cylinder and igniting it to force the piston down. The benefit of combining a DISI engine with i-stop (originally called SISS: Smart Idle Stop System) is that the system restarts the engine about twice as fast, and quieter, than conventional idle-stop systems.

Combining these two Mazda proprietary technologies and further measures like aerodynamic modifications, help the new Mazda 3 achieve approximately 14 percent lower fuel consumption (combined) than the previous Mazda 3.

When the driver stops the vehicle (red light, traffic jam) the engine stops automatically and sets itself to be ready for a prompt restart. As soon as the driver presses the clutch, the engine initiates the restart procedure automatically. This is a totally neutral operation for the driver.

The Mazda 3 i-stop Green Technology
When stopped at a traffic light or in a traffic jam, shutting off the idling engine can reduce fuel consumption by approximately 5 percent according to European city driving-mode tests. However, the drawback with conventional idle-stop systems is that they rely solely on the use of an electric motor to restart the engine. As such, they require a relatively long amount of time to achieve combustion in the engine when it restarts. In real-world driving, this means a lag between the moment the accelerator pedal is pressed down and the car begins to move, as well as vibration and noise.

The i-stop system for the new Mazda 3 leverages the DISI engine's direct-injection potential for improving fuel economy, restarting the engine quickly and quietly by injecting fuel directly into the cylinder and igniting it to force the piston down and set the crank in motion. The engine is controlled with precision to make this happen:

The Special engine requirements
In order to use combustion energy from the initial stage of restarting the engine, and to start the engine quickly, the following three conditions must be satisfied while the engine is stopped. (1) The engine must be able to inject fuel directly into the combustion chamber and ignite it; (2) an adequate amount of clean air must exist in the combustion chamber of the cylinder where the fuel is to be ignited; and (3) the computer control system must be able to determine which cylinder to fire immediately after starting the engine. The i-stop system, therefore, must use a direct-injection engine that can deliver fuel to the combustion chamber at high pressure, and that can easily ignite that fuel. Mazda's MZR 2.0-litre DISI petrol is the ideal engine to achieve this.

Mazda 3 Sedan, 2010

Mazda 3 Sedan, 2010

 

The new Mazda 3 Sedan is perfectly positioned for the rapidly changing automotive market. It offers a mix of quality, styling, power, dynamics and fit and finish that meets the demands of today's customers. In typical Mazda fashion, this new Mazda 3 Sedan will offer standard and optional equipment not found on other cars in its class - exactly what buyers want when seeking compact cars providing outstanding value.

This model arrives with an impressive pedigree, for the first-generation Mazda 3 earned 90 major awards from expert critics and achieved 1.8 million sales around the world during the last five years. The Mazda 3 accounts for one third of Mazda's sales and even at the end of its build life, the first-generation version continued to earn accolades - a leading consumer magazine recently naming it as one of the most reliable compact sedans available.

Mazda 3 Programme Manager Yoshiyuki Maeda established ambitious goals for the latest embodiment of the company's most popular car line, "We were determined to advance the Zoom-Zoom driving experience to new heights because that unique feeling lies at the very heart of Mazda. On the heels of the original Mazda 3's success, we aimed to again exceed the expectations of customers all over the world by a wide margin. This meant providing drivers with a sense of exhilaration - whether they were in motion, seated in the Mazda 3, or enjoying its appearance from outside."

Describing what it takes to develop a true 'world car', Maeda added: "The development process began with careful study and identification of what features and performance qualities would be needed. That initial phase ended with my conclusion that every driving characteristic was eligible for improvement to reach our Zoom-Zoom goals. Mazda engineering and R&D departments in Japan, Europe, and the US all contributed to the Mazda 3's renewal effort and the development of the company's new world car."

EXTERIOR DESIGN
Chief designer Kunihiko Kurisu's mission was to remain faithful to the Mazda 3's existing visual identity while evolving its appearance with richer, bolder design strokes. Infusing each subsequent new model with more emotional aesthetics is a longstanding Mazda tradition. The key Mazda 3 exterior design highlights are:
    * A move toward a more unified Mazda global 'family face'
    * A reinforced frontal identity which integrates the lower air intake with a more emphatic and instantly recognizable five-point grille
    * Major design elements focus on, or flow toward, the vehicle's central axis, to stress power and dynamism. At the front, fascia lines converge on the centrepoint at the bottom of the grille. At the rear, the boot lid's surface has a distinctive centre crease
    * A compact cabin, high deck surfaces, and flowing C-pillar features, which were inspired by the classic coupe profile, as seen on the 2009 Mazda 6
    * Bonnet and side surfaces which are shaped to reflect light and physical surroundings
    * A subtle wedge-shape and curving side character lines which are shared with other Mazda models, giving the Mazda 3 Sedan a strong sense of impending motion - like a predator poised to strike
    * A new Adaptive Front Lighting System with self-levelling bi-xenon headlamps - added as standard on Grand Touring models. The Mazda 3 Sedan is the first compact offered for sale in the US with such an advanced lighting system
    * Exterior design elements which contribute to the car's function by minimizing aerodynamic drag and lift while providing the powertrain, chassis, and interior with adequate air flow for cooling and climate control

To supplement the four-door sedan introduced at the 2008 Los Angeles Auto Show, a five-door hatchback Mazda 3 will arrive later.

INTERIOR DESIGN
Inside, the new Mazda 3 Sedan offers a sporty yet highly refined cabin - the dash sweeping dramatically from its centre to the sides of the cabin. The large gauge instrument cluster and centre stack are positioned to tightly link the driver's limbs and senses to the car's instruments and controls.

Studies into the range of motion helped position all controls at an ideal reach, while the slant of the instrument panel optimises operating efficiency and provides an attractive focal point. Key knobs and switches are positioned at the same level as the steering wheel and the gear level as part of an interior design which is based on Mazda's Human Machine Interface concept.

All the information a driver needs is readily available in one concentrated area - thereby minimising distractions from the road ahead. A Multi-Information Display is positioned high on the centre portion of the instrument panel to further reduce distraction. Navigation, audio, and trip computer information is provided in this convenient and easy-to-view location.

The front seat cushions have been extended by nearly an inch (compared to the outgoing car), in order to provide improved thigh support. Backrests are 1.4-inches taller and re-contoured for improved driving posture. For the higher grade models, the upper side bolsters have been canted inward for heightened torso support during aggressive cornering. A three-position memory function has been added to cars equipped with power seats - another first for the segment, and not offered at any price on any competitor's compact car. Upon approach to the car, the driver's seat automatically adjusts to the settings chosen by up to three different drivers by recognising the code of the key fob.

To provide a top-quality interior appearance, the number of parting lines is minimized and soft-touch surfaces show an elegant grained texture. An interactive lighting system enhances the cabin's ambience and sense of tranquillity. Upon entry, illumination rises in intensity in a programmed manner. Occupants are welcomed by foot-well and door-handle lamps. Next, instrument cluster, centre stack, audio and climate controls brighten. When a driver or front seat occupant touches an audio or AC switch, a change in illumination acknowledges that the command has been received.

Dual-zone automatic air conditioning is an option. Other special features that distinguish this car include: a BOSE 10-speaker premium surround sound system, connectivity for cell phones and portable media players, a dock for iPods, and Sirius satellite radio. An advanced keyless entry system includes push-button engine starting. Other options include rain-sensing wipers, heated door mirrors, leather upholstery, and heated seats.

Overall, the details included in the new Mazda 3 Sedan all contribute to the sense of quality in the car. This is a vehicle that offers equipment, fit and finish not found in other vehicles in its class, and in the current economic climate helps to position Mazda 3 Sedan perfectly for buyers seeking a way to spend less but get more.

Mazda 3 MPS, 2010

Mazda 3 MPS, 2010

 
The next-generation Mazda 3 MPS is one of the world's most powerful front-wheel drive compact cars. It takes the all-new Mazda 3 hatchback as its base and raises it to new levels of driving excitement with an updated MZR 2.3-litre DISI turbo petrol engine, increased body shell rigidity and an evolved suspension. To this it adds exclusive design cues and materials to deliver a next-generation compact flagship that is even more fun to own and drive than the current model.

On top of its high performance level - one of the best in the category - the all-new Mazda 3 MPS was developed according to Mazda's long-term vision for technology development. Advanced Mazda engine and catalytic converter technologies mean the new model has an optimized power delivery, uses less fuel, and has cleaner emissions than the previous Mazda 3 MPS model.

Design - A More Expressive and Dynamic Design
The design theme for the all-new Mazda 3 called on the development team to evolve the model's visual identity to create a sportier, more aggressive appearance. The end result is a more emotionally appealing design that takes the sporty, agile compact nature of the all-new Mazda 3 hatchback to a new level of sporty refinement.

Exterior Design
A new air intake for the intercooler is introduced to the centre of the all-new Mazda 3 MPS bonnet, hinting at the power underneath. The front fender and front bumper designs are exclusive to the MPS, while subtle intonation added to the surface and character lines give the exterior an expressive and dynamic flair. The front grille and lower bumper sections share the same black metallic paint finish. These are framed by cylindrical bi-xenon headlamps and round fog lamps, to underscore the car's premium character.

Mazda 3 MPS
Silhouette and rear end

At the sides, subtle wedge-shaped and curving side character lines, along with a side under spoiler, accentuate the car's sporty, low centre of gravity. The view from the rear features a large floating rear spoiler (depending on market) that balances out the tight look begun by the new front end and adds to the compact's aggressive image. LED tail lamps have an inner lens that adds a sense of greater transparency when the lamps are not lit.

One the segment's best for aerodynamic performance
Beginning with the all-new Mazda 3 5-door hatchback, which has one of the segment's lowest coefficients of drag, MPS developers added a number of exterior features optimised for aerodynamic efficiency. These include the large front and rear bumpers, a large floating rear roof spoiler and front under spoiler. The result is aerodynamic performance that provides stability and easy control when travelling straight, changing lanes, or overtaking other vehicles at high speeds. The shape of the A-pillars and door mirrors were also designed keeping aerodynamic efficiency in mind, while increased rigidity around the door sashes, delivers improved sealing of the doors to reduce wind noise.

The Wheels and tyres
Mazda introduces all-new 18-inch (18 x 7.5J) aluminium alloy wheels designed exclusively for the Mazda 3 MPS using the same design theme as the Mazda RX-8 wheels. These have a strong, three-dimensional form that helps the car look nimble and aggressive when seen from the side.

The Interior design
Front seat area
The dashboard of the new Mazda 3 MPS is designed to give a roomy feel at the front. This is combined with a large centre console and a driver-orientated, wrap-around cockpit with just the right feeling of snugness. Exacting calculation was applied to designing the slant of the centre console and in positioning the gearshift lever closer to the driver.

New turbo boost gauge
The hoodless independent blackout speedometer and tachometer express sportiness through their design. The tachometer features a red MPS logo and a needle that travels 260 degrees as opposed to the 190-degree rotation on other Mazda 3 models. The instrument cluster for the all-new MPS also includes an LED turbo boost gauge positioned between the meters, which heightens the car's high-performance feel.

Semi-bucket front seats
The all-new MPS provides semi-bucket front seats for a great fit and exceptional torso and thigh support, a real must in a car this sporty. The front edge of the seat cushions is enlarged to improve the fit under the thighs, and the seatback length is extended to provide greater support. The MPS upholstery features an exclusive black base colour with a red graphic design and red stitching.

Materials and colour
Developers were careful in selecting materials and surface finishes for the interior that will excite the driver and passengers every time they take a seat in the car. Black is the keynote colour employed throughout the interior, while the seats and trim fabric have an organic red graphic design. This MPS-exclusive design is distributed throughout, with red stitching enhancing the sporty interior character on the steering wheel, seats, door trim, shift lever boot, and centre armrest.

Mazda 3, 2010

Mazda 3, 2010

 
 
 
 

The Exterior design - expressive and emotional styling
A distinctive new front fascia is formed by the 5-point grille and openings at the front corners. These design cues combine with the sculpted shape of the hood and the bold, expressive lines that connect the hood to the front pillars. All the lines seem to flow into the center just below the 5-point grille, which creates a stronger expression of power and dynamism. From the side, the front fender line smoothly morphs into the beltline, clearly identifying the vehicle as a Mazda and communicating dynamism. The line of the side sill curves up and seems to connect with the rear spoiler to emphasize the vehicle's compact size and express its agility. In order to make the surface more expressive, Mazda designers slightly elaborated the depth of the hood edge, front fenders and the three-dimensional shape of the protruding body sides, carefully crafting curves that subtly reflect changes in natural light.

The rear view boasts a sporty design with wide stance. The strongest features are the protruding shoulders and emphasized center-focus design. This concept was carried over from the first generation Mazda 3 and made bolder to represent expressiveness. All the lines of the rear view are designed to concentrate on the brand symbol in the center. The impressive C-pillar design was also inherited from the first-generation Mazda 3 and made more prominent. This was made possible by Mazda's expertise in stamping technology.

The Interior design : sophisticated, sporty, and high quality
The inside of Mazda 3 is a sporty yet highly refined cabin. The dashboard sweeps out from the center toward both sides with dynamic flair as though it is flexing powerful muscles. The large center display and controls are laid out around the driver to deliver just the right feeling of snugness. The angle of the center panel was adjusted after careful analysis of the driver's hand movement, producing a more stylish and dynamic design. A soft, wood grained surface with minimized parting lines on the top of the dashboard enhances the interior quality. The new interactive lighting control enhances the driver's connection with the vehicle.

The Powertrains for all driving experiences
The powertrains combine Mazda's typical Zoom-Zoom driving experience with excellent environmental performance to provide exhilarating driving. They transmit just the right amount of G force that perfectly matches the vehicle's actual acceleration. This provides the driver with a more refined experience of oneness with the car. The new engine line up has been tailored for European customers and now includes the newly developed MZR-CD 2.2-litre turbo diesel engine, carried over from the all-new Mazda 6, in addition to the MZR-1.6-litre and 2.0-litre gasoline engines and the MZ-CD 1.6-litre turbo diesel. It is a high-performance clean diesel engine with top class output, fuel economy and quietness. The MZR-CD 2.2-litre turbo diesel engine will be offered in two variants: a high power version with a maximum torque of 400 Nm/1,800-3,000 rpm and a maximum output of 136 kW (185 PS)/3500 rpm, and a standard power version with a maximum torque of 360 Nm/1,800-2,600 rpm and a maximum output of 110 kW (150 PS)/3500 rpm. Both versions have outstanding clean emissions performance, comply with the Euro Stage 5 regulations and feature a Mazda developed unique Diesel Particulate Filter (DPF) technology for more efficient regeneration. Fuel economy is also greatly improved by 7 to 10 percent compared to the MZR-CD 2.0-litre engine equipped in the existing model, attaining 5.4 l/100 km for the standard power version and 5.6 l/100 km for the high power version.

The MZR 2.0-litre petrol engine underfloor catalyst is the world's first vehicle catalyst to be constructed with single nanotechnology, which controls even finer materials structures than nanotechnology. It is used to embed individual particles of precious metals, which are less than 5 nanometers in diameter, into the catalyst base material. This new development enables Mazda to reduce the amount of expensive precious metals such as platinum and palladium by 70 to 90 percent without impairing catalyst performance. The catalyst is an important part of Mazda's efforts to reduce reliance on limited resources.

Power steering, suspension and brake systems
To deliver just the right balance between fuel economy, light steering-wheel operation and a feeling of stability, all configurations of the all-new Madza3 are equipped with the Electro-Hydraulic Power Assist Steering system (EHPAS) that has earned high acclaim on the first generation Mazda 3. The suspension is based on the first generation Mazda 3 system, and has been enhanced to ensure even nimbler response to steering wheel operation, and also to improve roll control and maintain a flatter ride by strengthening the suspension damping. In the brake system, the vacuum booster has been tuned and the feeling of initial brake application has been optimized. The overall result is outstanding response and reassuring linearity under all braking conditions.

Mazda RX-8, 2009

Mazda RX-8, 2009





Launched in 2003, the Mazda RX-8 hit the global market with a serious bang. The RX-8 has won more than 50 global awards since its release including 2003 RJC Car of the Year in Japan Australia's Wheels magazine's Car of the Year for 2003, 2003 International Engine of the Year, 2004 Singapore Car of the Year, the 2004 U.S. Best Sports Car and UK Car of the Year 2004. It was also named on Car and Driver magazine's Ten Best list for 2004, 2005, and 2006. All together, Mazda has sold nearly 167,000 RX-8s around the world.

STYLING INNOVATION - REFRESHED DESIGN CUES PROVIDE "HIGHQUALITY" DYNAMISM

Mazda RX-8 was designed with an athletically sculpted exterior that provides a sense of originality that's unrivaled in the marketplace today. The new Mazda RX-8 receives design enhancements that are meant to freshen the styling and give Mazda RX-8 a new look, without impairing the basic design theme. Refinements for the new Mazda RX-8 include restyled front and rear bumpers and front fascia; sporty, high quality finish front and rear headlamps; and larger exhaust pipes (now measuring 90 mm across). The new Mazda RX-8 also offers a new five-spoke wheel design featuring a symbolic and sporty design reminiscent of the rotary engine, with different arrangements for each wheel size.

Taut muscular lines give Mazda RX-8 the liberating look of an athlete in motion. The muscular styling maintains classic sports car proportions while adding a Zoom-Zoom edge that is unmistakably Mazda.

The RX-8's unique "freestyle" four-door design is proof that a true sports car does not need to sacrifice space or convenience for performance. The advanced design of the rear-hinged rear doors provides a large door opening, allowing adult-sized passengers to easily enter and exit the vehicle. This design is also advantageous when securing a baby or a small child in the back seat. With a spacious rear seat area providing ample passenger room for four full-size adults, and enough trunk space for a weekend's worth of luggage, this sports car proves its versatility.

The Mazda RX-8's exterior styling presents a genuine sports car form, while the interior boasts a comfortable and intelligently designed cabin. Minor enhancements were made for the new Mazda RX-8 to provide a simple and functional interior design that supports driving pleasure. The center IP shape was redesigned to give a feeling of dynamic movement, a variable red-zone was added to the tachometer that will rise as the engine comes to operating temperature and a new steering wheel and redesigned front and rear seats are also added.

Mazda MX-5 Superlight Concept, 2009

Mazda MX-5 Superlight Concept, 2009


 
The Mazda MX-5 Superlight Concept is an answer to the world of automobiles and individual mobility moving towards energy efficiency, environmental compatibility and uncompromised safety - along with dynamic attributes and driving fun. In its efforts to offer pure driving enjoyment, while meeting its ecological and social responsibilities, Mazda has been focusing on weight reduction as a core base technology. For 20 years, reducing weight has been a tradition with the Mazda MX-5. It provided the inspiration for the radical design of Mazda's latest show car and its radical interpretation of the cult roadster.

Exterior Design
The Mazda MX-5 Superlight Concept was to strengthen these bonds even further. By doing this without a windshield, the retractable top and its frame, designers achieved an important step in this direction. As the Mazda MX-5 Superlight Concept, the allweather production roadster has mutated into a driving machine that lets sports car enthusiasts enjoy the natural surroundings unfiltered and tangible. Not only does the wind blow unimpeded during driving, pilot and co-pilot can also experience the sounds, smells and temperature changes of their immediate surroundings. And finally, the show car's intense bond between the driver and the technology of the vehicle gives it a unique closeness that can only be found in stronger form in the cockpit of a race car.

The Mazda designers created special roll-over bars, not only because they are very sporty-looking, but also to contribute to aerodynamic efficiency. These also make it clear that roll-over protection is important in this concept. And they prevent wind turbulence around the heads of the passengers, from whom the law would require the wearing of helmets while driving.

By removing equipment not vital to driving, and by replacing vital things with components that support the unique concept of the vehicle, designers sharpened the character of the Mazda MX-5 Superlight Concept.

Cause there is no windshield, for instance, there is obviously no need for wipers. The roadster show car's completely open design makes the need for outer door handles, side windows and their openers unnecessary. A single, filigree aluminium, wide-angle mirror gives a good view of the road behind. It's placed inside an extension of the bonnet. Front and rear lights are the same as those of the production model with additional LED lamps at the front, and brake lights at the back of each roll-over bar, which contribute to the roadster's sporty look.

Mazda MX-5, 2009

Mazda MX-5, 2009





The Exterior Design: A Fusion of New Mazda Elements and an Unmistakable MX-5 Look
The front grille has been enlarged and changed from an oval shape to the five-point grille that forms part of the well-known Mazda family face. Combined with tautly styled headlights and lowing fog- lamp bezels, the new grille creates a reined and athletic expression.
The five points of the grille are slightly rounded the new shape of the front bumper, with corners that extend downwards, enhances the dynamic look and improves the aerodynamics.
The rear bumper has a new design that makes the rear look wider, sportier, and more integrated into the body. The rear combination lamps inherit the traditional MX-5 elliptical motif, and protrude further outboard for greater aerodynamic efficiency.

The Roadster Coupe's more Upscale Identity
The Mazda MX-5 Roadster Coupe, which features a groundbreaking powered roof system, also incorporates several design changes that further emphasize its more upscale identity and distinguish it from the soft-top version.
    * Front grille: Whereas the soft-top version has a in-type grille, the Roadster Coupe has a mesh grille that is framed by a chrome ring.
    * Headlamp inner bezels: The headlamp inner bezels are painted silver on the soft-top version, but have a chrome finish on the Roadster Coupe.
    * Fog-lamp inner bezels: The fog lamp inner bezels are black on the soft-top version, but are painted silver on the Roadster Coupe.
    * Outer door handles: The outer door handles are body-coloured on the soft-top version, but have a chrome finish on the Roadster Coupe.
    * High-mounted stop lamp: The high-mounted stop lamp has a red lens on the soft-top version, but a clear lens on the Roadster Coupe.

The New Wheel Designs
The MX-5 is available with 16-inch and 17-inch aluminium wheels. The 16-inch wheels have five sets of twin spokes for a lightweight look. The 17-inch wheels have 10 twisted spokes for a stronger impression of power and dynamism.

The Interior Design: Higher Than Ever Quality and Driver- Friendliness
The interior design delivers the Mazda MX-5's traditional combination of comfortable snugness below shoulder level and openness above shoulder level. It also reflects customer feedback in the form of enhanced quality and driver-friendly features.
The decorative surfaces on the instrument panel have been changed from glossy piano black to dark silver, which has a subtler, higher- quality look befitting a sports car. The meters have new graphics for higher legibility. The climate-control dials on the centre stack have each been given a silver-coloured ring for a higher-quality look. A protrusion has been eliminated from the outer surface of each door pocket to create more leg space. And the door and centre-console armrests have each been given a soft pad for a better feel.
Recaro seats designed exclusively for the MX-5 are available in certain regions. They are upholstered in leather and perforated Alcantara for a sporty look, and they combine excellent support with easy ingress and egress.

Evolved Jinba Ittai for Enhanced Fun-To-Drive
The Jinba Ittai feeling on which Mazda has always focused with the Mazda MX-5 defines the kind of spontaneous car-and-driver interaction that anyone can experience whether they're driving the MX-5 in town, on twisty roads, or on an open highway. With the latest facelift, Mazda engineers evolved the attributes in the "driving", "cornering", "braking", and "listening" categories in the fishbone chart to realize performance that lets drivers enjoy the feeling of oneness with the car to an even greater degree.

Mazda 6 US-spec, 2009

Mazda 6 US-spec, 2009


 
 

The original Mazda 6, introduced in late 2002 for the 2003 model year, made Zoom-Zoom the two most evocative words in the automotive lexicon. This sport sedan was the first Mazda vehicle to benefit from the spirit of a true sports car infused in a five-passenger, 4-door sedan. That revolutionary combination created a commotion in the mid-size class where strict practicality, affordability, and economy of operation usually leave no room for driving enjoyment. The original Mazda 6's vitality is what set it apart from competitors.

Times and tastes change. The all-new 2009 Mazda 6 takes everything learned in that first-generation car, as well as lessons learned from volumes of customer feedback, and proves Mazda's commitment to continuous improvement. Most important, though, this is the first Mazda vehicle designed, engineered, developed, and manufactured on US soil with the intention of surpassing American customer needs in countless categories.

Hiroshi Kajiyama served as program engineer for the new Mazda 6. Kajiyama, who graduated in electrical engineering at the Hiroshima Institute of Technology, brings 21 years of service at Mazda, ample experience with the first generation Mazda 6, and several years of program management to the project. Unlike most engineers, Kajiyama treats the Mazda 6 as a work of art rather than an inanimate machine. That attitude was key to instilling the soul of a sports car in the new Mazda 6.

Kajiyama established ambitious goals and high standards. To be widely recognized as the best vehicle available in the mid-size market, the Mazda 6's underlying concept rests solidly on three fundamental pillars:

A Unique Experience. The Mazda 6 inspires pride of ownership. Notes Kajiyama, "By elevating the quality level with exquisite craftsmanship, each Mazda 6 will form a strong bond and a powerful emotional connection with its owner. This relationship is reinforced by driving pleasure keyed to adult tastes, comfort that the driver and every passenger can feel and appreciate, and numerous special features that make every trip, long or short, a highly memorable and pleasurable experience."

An Insightful Package. The Mazda 6 goes beyond existing mid-size sedan solutions to provide innovative packaging inside a larger envelope, highly flexible seating and storage space, and an unusually attractive appearance. Kajiyama adds, "By building on our strengths and accomplishments, we're able to make the Mazda 6 the most versatile, comfortable, and enjoyable automobile this company has ever produced. This is what we mean by the evolution of Zoom-Zoom."

Mazda BT-50, 2009

Mazda BT-50, 2009

 
 
 Since launch in 2006, the stylish Mazda BT-50 pickup has been very popular throughout the world. This tough but sophisticated-looking lifestyle vehicle can do it all - carry bricks to a construction site or a surfboard to the beach, and after a wash-up cut a good figure for a night on the town. Its appeal reaches across target groups like no other car in the Mazda portfolio: from commercial users in rural areas of Europe and Asia, to fire-fighters in Greece, to young urbanites with sporty or adventurous lifestyles. Since launch, Mazda has sold over 60,000 units globally (over 19,000 in Europe) while winning several awards along the way during the 30 months period. These include Ute of the Year in Australia and Off-road Competition's Car of the Year in Russia.

Exterior updates for higher quality look and more choice
The Mazda BT-50 facelift can handle whatever a commercial user or an off-road adventurous lifestyle demand of it. As with the outgoing model, three cab versions are available (depending on market) with room for two (Regular Cab), four (Freestyle Cab) or five passengers (Double Cab) and cargo box lengths of 2,280 mm, 1,753 mm or 1,530 mm respectively. It retains its high quality, single-fascia front bumper, but now with an all-new design. The facelift front end has a large 'oblique H' with upper arms that grow out of the bonnet's character lines, and lower arms at the base of the lower bumper. This visually integrates the individual parts of the front end into a strong, harmonious Mazda family face. The Mazda five-point grille, for instance, is more clearly defined here, and the trapezoidal shapes of lower openings hint at the pickup's high level of driving fun. Designers then added new front headlamps with bright silver mouldings that make the front end seem wider giving the facelift version a stylish and muscular look.

More variability - a larger list of exterior combinations
The Mazda BT-50 facelift adds exterior features that will allow customers to differentiate their own models to a greater degree than ever before. The choice of single colours is increased from 9 to 11, including 5 new colours, and all 3 two-tone colours are replaced - highlight silver metallic combined with either titanium grey metallic, lagoon blue mica or black mica. Body coloured overfenders are now standard for all mica/metallic exterior colours on Mid and High Grades, the vehicle's side sills are now in a new silver metallic colour and a new 16-inch alloy wheel design (for 4WD models) is introduced. Customers looking for even more style can now order dark tinted glass for the side and rear windows for High Grade models as well (depending on market).

Interior - new fabrics, colours and lighting
The original Mazda BT-50 delivered interior stylishness and build quality befitting a sedan. The facelift model inherits its predecessor's interior it and finish with very small gaps between the dashboard and door trim, and adds higher quality fabrics, colours and lighting for even more sedan-like feel. For a fresher ambiance, lighting for the driver metres, climate and audio controls, and for the indirect lighting at the base of the centre console, is now amber. New fabrics are also introduced for the seats and door trim. High and Mid Grade seats now have a new chequered fabric for the seat centre, woven to give off a quality lustre, and Low Grade seats also have new patterned fabrics in the centre, replacing the plain grey of the outgoing model. The centre panel is also upgraded for the Mazda BT-50 facelift with an all-silver look that matches the new fabrics and lighting for more sedan-like sophistication.

Comfort like a passenger car
Sedan-like ambience is combined with sedan-like comfort, equipment, and interior functionality you would expect from a pickup. All versions of the Mazda BT-50 facelift have front seats that offer full sedan-like comfort, and the Double Cab features a large centre armrest between its bench-type rear seats, providing four adults with superior comfort. The pickup's high seating position is optimised by a front bonnet and a cargo box wall designed to support front and rear visibility, which is important for a vehicle with as many uses as this. The facelift version adds new heated side mirrors (depending on grade), which defog/defrost quickly. Inherited from the original Mazda BT-50 is a climate system that includes a two-intake duct blower for superior heating/cooling. Mazda BT-50 facelift also inherits its quiet interior - with large amounts of insulation, a low-noise air cleaner and radiator fan, and a smooth-running common-rail diesel with dual-mass flywheel.

Superior functionality inside and out
Loading and using the Mazda BT-50 facelift on a daily basis is easy, making it the ideal companion for work or play. The Freestyle Cab features Mazda's unique centre-opening doors that provide a wide opening for getting into and out of the rear seats, or for loading something behind the front seats. It still has a single-action lever in the tailgate for easy opening and closing, there are rope hooks on the outer edge or the insides of the cargo-box walls, and there are load rest stoppers (depending on grade and market) at the rear of the cabin that can be raised to secure items too long for the cargo bed. There are even guiding grooves on the cargo-box walls for sliding in dividers, which create two load areas in the back.

The front seats are slide adjustable and can be tilted forward. The steering wheel is tilt adjustable, allowing just about anyone to find the right driving position. Interior storage is at a level not usually seen in a pickup interior. There is a slide-out tray above the glovebox strong enough to hold up to 10 kg, a large floor console storage box and even a handy tool box under the rear cushion of the left rear seat (Freestyle Cab). There are pockets in the front and rear doors for bottles, power adjustable side mirrors, and a remote fuel cap cover release. Power windows with safety power cut-off all around and a one-touch up and down function for the driver, power door lock/unlock from the driver's seat, as well as a retractable key with keyless entry system (on Mid and High Grades) provide additional convenience.

New equipment - AUX jack for connecting an MP3 player
To take full advantage of the Mazda BT-50 facelift's quiet interior is an audio system (depending on grade and market) that employs a high-performance amplifier and audio level control (ALC), which automatically adjusts the tone characteristics between three levels to match the speed of the pickup at any given moment for just the right volume level. The audio system includes a radio, a CD player and up to four speakers (Regular Cab has two speakers). High Grade versions are equipped with a six speaker system with a 6-CD changer. The facelift adds an auxiliary (AUX) jack to the audio system, which allows you to play music from your MP3 player directly using the audio system of the vehicle.

Strong and fun to drive
The Mazda BT-50 facelift retains the MZR-CD 2.5-litre common-rail from its predecessor, known for being strong, reined and fuel- efficient. It is a DOHC 16-valve diesel engine that employs a variable- geometry turbo charger and a large intercooler to produce maximum power of 105 kW/143 PS at 3,500 rpm, and maximum torque of 330 Nm as low as 1,800 rpm. This gives lively engine response to pedal input for Zoom-Zoom driving fun when unloaded, and takes care of business towing up to 3,000 kg with a braked trailer (4x4 models). A variable swirl control valve (VSCV) is also employed and is combined with an optimised exhaust gas recirculation (EGR) system and a high-efficiency EGR cooler to ensure Euro Stage IV compliance and low tax costs in most countries.

The facelift version of the Mazda BT-50 inherits the acclaimed rear-wheel drive transmission of the outgoing model that meets the demands of commercial customers, lifestyle customers, or both at the same time. It has Mazda's precise, easy-to-shift five-speed manual transmission in either a 2WD only version or a 2WD/4WD version. The latter transmission not only has a large and robust transfer case that converts the engine's high torque into great traction in any on-road or off-road situation, it is also easy and convenient to use. It includes an electric Remote Free Wheel (RFW) hub system that allows shifting between 2WD and 4WD while driving up to 100 km/h. Back on solid roads and in 2WD mode, pushing the 'RFW' button automatically disconnects the front differential and prop shaft from the front wheels. This function enables you to drive at motorway speed right after driving offroad, without stopping in between. It contributes to better fuel economy, lower noise and optimal durability of the transmission. All models (except some 2WD Low Grade versions) are equipped with a rear limited- slip differential (LSD) with an enhanced torque ratio in line with the engine's higher torque, which automatically adjusts drive power between the two rear wheels to maintain traction on just about all kinds of surfaces.

Mazda 6 SAP Wagon, 2009

Mazda 6 SAP Wagon, 2009


 
 


The second-generation Mazda 6 was launched in November 2007 and represented an evolution of Mazda Zoom-Zoom.

Mazda 6 has always been a driver's car and with the launch of the new-generation model last year, the fun factor was improved even further. The second-generation Mazda 6 was introduced originally with four different engines - three lively MZR petrol engines (in 2.5, 2.0 and 1.8-litre displacements) delivering power between 170 PS to 120 PS, and a MZR-CD 2.0-litre common-rail turbo diesel producing 140 PS and 330 Nm of torque. Mazda now introduces a new clean turbo diesel in three power derivatives that is one of the quietest and most powerful in its class.

Mazda's new MZR-CD 2.2-litre turbo diesel has a lively yet cultivated character that will offer a truly exclusive driving experience under the bonnet of the second-generation Mazda 6. Offered in three versions producing 185, 163 and 125 PS of maximum output and powerful torque of 400, 360 and 310 Nm respectively, the MZR- CD 2.2 will meet the demands of a wide spectrum of customers in Europe.

Delivering the Power - Output and Torque

To realise this kind of power and torque with 2.2-litres of displacement, the MZR-CD 2.2 employs a highly efficient variable-geometry turbo charger (VGT) with curved (instead of straight) vanes on the turbine (exhaust) side. This increases maximum available torque at both low and high engine speeds, while also increasing all-important low- end response (as low as only 1,800 rpm with a lat maximum torque curve that continues until 3,000 rpm) that contributes smooth and powerful driving feel. When combined with an abradable seal on the compressor side (intake side), which reduces the clearance between the blade and the compressor housing, these deliver superior turbocharger response at just about all engine speeds.

Converting the engine's combustion energy into this much engine torque meant the pistons had to be designed to take the resulting high combustion pressure and temperatures. As a consequence, the pistons are made of an aluminium alloy with improved high- temperature fatigue strength. A half-Keystone cross-section top- ring with improved carbon scavenging abilities is used, and the groove for the top ring is made more durable with the adoption of a cooled ring carrier that increases the groove's cooling capability.

Mazda engineers also increased the fuel injection pressure to 200 MPa (by comparison, the previous generation MZR-CD 2.0- litre turbo diesel uses 180 MPa). They realised this by making functional improvements to the high-pressure pump, among other improvements, and by new injectors featuring 10 spray holes per injector (instead of the 6 spray holes for the MZR-CD 2.0-litre) that are smaller (reduced from 0.13 mm to just 0.119 mm). These changes enable more precise injection timing, and an increase in the number of times of injection and injection amount. And it allowed the fuel injection patterns at transitional states to be more precisely controlled. As a result, the Mazda 6 MZR-CD 2.2 provides superior acceleration in those situations you need it most, like entering the motorway. It also surpasses its competitors in lower speed acceleration. Acceleration in 3rd gear from 50 to 100 km/h, for example, is 1.7 seconds faster than the MZR-CD 2.0-litre.

Low Fuel Consumption
This new diesel engine also meets the requirements of Mazda's 'Sustainable Zoom-Zoom' plan by being frugal at the pump: all power derivatives use between 5.5 and 5.7 litres of fuel per 100 km (combined), some of the segment's lowest.

New injector with 10 spray holes

It achieves this by employing highly responsive solenoids for the common-rail injection system that achieve a minimum injection interval of just 0.2 ms (the MZR-CD 2.0 is 0.3 ms), which speeds up the minimum injection interval by about 30 percent, improves its responsiveness and lowers fuel usage. Fuel is also saved by lowering the compression ratio to 16.3:1 and utilizing the temperature cooling effect this causes, which secures more mixing time until ignition, and allows a more precise fuel-injection pattern. As a result, fuel consumption is a low 5.5 to 5.7 litres (depending on derivative) with CO 2 emissions from between 147 to 152 g/km. In fact, the MZR- CD 2.2-litre offers substantially higher power and torque than the previous-generation MZR-CD 2.0-litre, while delivering equal levels of fuel consumption and CO 2 emissions.

Low Emissions - Particulate Filter with World's First Ceramic Support Matrix Structure

Mazda engineers not only made the new 2.2-litre turbo diesel powerful and low consumption, they also lowered the amount of raw emissions and raised the efficiency of its after-treatment technologies. The engine's highly responsive fuel-injection technologies have new injectors (see above) that yield better atomized spray characteristics. These are combined with an exhaust-gas recirculation (EGR) system with a cooler bypass structure - that decreases unburned gases and NOx - and the high- response solenoids described above, to realise superior emissions performance without sacrificing power.

Emissions are then treated by a diesel particulate filter that uses a unique Mazda-developed, ceramic support matrix structure, which is the first of its kind to go into production in the world. Previous diesel particulate filters converted particulate matter (PM) into CO 2 by reacting the PM with the oxygen in the exhaust gas at the surface of the catalytic particle. This meant that the time needed for filter regeneration was determined by the amount of oxygen on the surface of the catalyst.

When the temperature of the exhaust gas is raised to quicken the regeneration time, then technological issues - like higher fuel usage or the ceramics exceeding their thermal resistance limit - can occur. Mazda solved these issues by using highly thermal resistant material for the ceramic monolith of its new diesel particulate filter, and designing the internal structure of the ceramic support matrix with passages for oxygen to enable a large amount of oxygen to be utilized for PM combustion. With this, Mazda has succeeded in significantly increasing the PM combustion speed. As a result, the number of times the diesel particulate filter has to regenerate (in combined mode) is cut in half, and the time necessary for each regeneration phase is shortened by one third. For owners of the new Mazda 6 MZR-CD 2.2-litre turbo diesel, this means worry-free filter regeneration and, because fewer regeneration phases are required and each takes less time, less fuel consumption overall.

Running Quiet
The new Mazda 6 MZR-CD 2.2-litre common-rail not only offers superior output, fuel economy and emissions performance, it is also one of the quietest engines in its segment with this amount of torque. This ensures a driving experience that is one of the non- premium segment's most exclusive. To achieve this, the new engine has a lower block with a very rigid aluminium-alloy structure, with the bottom of the cylinder block skirt and the cylinder block's main bearing caps bolted to the lower block at 18 separate locations. This high structural rigidity is combined with a front chain-driven cassette-type balancer shaft to suppress booming noise and lower radiated noise, and to deliver optimised pedal response and engine sound for a reined acceleration feel.

Packaging and Weight Management

Keeping the new MZR-CD 2.2-litre engine as close as possible in size and weight to that of the MZR-CD 2.0-litre diesel was a key factor in ensuring exhilarating performance combined with fuel efficiency and low emissions. Some of the newly adopted technologies, such as the balancer shaft and DOHC, result in increased size and weight. Nonetheless, numerous innovations were added to manage size and weight increases, with the goal of maintaining packaging and keeping the weight increase within just 6.0 kg of the previous MZR- CD 2.0-litre turbo diesel.

Due to the increase in displacement, the stroke of the MZR-CD 2.2 was lengthened by 8 mm compared to the MZR-CD 2.0. At the same time, the overall length of the connecting rods was shortened by optimizing their design. As a result, their weight remains at the same level as in the MZR-CD 2.0. The adoption of a balancer shaft that decreases vibration caused by reciprocating motion made a thinner cylinder block with fewer ribs possible (if the MZR-CD 2.2 had no balancer shaft, the cylinder block would have been 1.9 kg heavier than that of MZR-CD 2.0, and its crankshaft 1.3 kg heavier.). Furthermore, decrease in size and weight was achieved by making the balancer housing, oil pump housing, and the oil suction pipe a single structure. To achieve even more weight reduction, while increasing the cooling capability of the new engine, the oil cooler is made of aluminium (-0.6 kg). The weight of the cam cover is also reduced by making it out of plastic (-1.0 kg).

Mazda 6 - the first Mazda with Rear Vehicle Monitoring System


Not only does the Mazda 6 2.2-litre diesel meet the requirements of Mazda's 'Sustainable Zoom-Zoom' strategy by delivering high power and torque with low consumption, it also meets the strategy's focus on improved safety by introducing a new vehicle monitoring system to the line-up as an enhancement to its already long list of active safety features. Employing two wide-angle, 24 GHz microwave radar units on the right and left side of the rear bumper, this system is a fully independent active safety feature that detects and warns the driver of an approaching vehicle - when driving at speeds over 60 kilometers per hour - before he has a chance to change lanes by mistake. It also detects vehicles driving in the blind spot area, and is effective even in bad weather conditions.
