Rinspeed iChange Concept, 2009

The Swiss auto powerhouse Rinspeed presents the Rinspeed iChange Concept, the world's first car whose body adapts to the number of passengers on board. For Rinspeed boss Rinderknecht the vehicle is more than just a clever concept car. "The Rinspeed iChange Concept is a symbol for the fundamental changes the auto industry undergoes worldwide. And it is clear that only those companies will survive that have innovative answers for the demands of a new automotive era." The visionary Rinderknecht is convinced that the days of gas-guzzling behemoths are coming to an end: "The Rinspeed iChange Concept is a signal for the coming global changes to individual mobility. We need to be ready to meet these challenges with new ideas."

In seconds a streamlined one-seater sports car transforms into a comfortable car with ample room for three. The trick: At the push of a button the rear end of the teardrop-shaped car magically pops up. "We have designed and built an extremely flexible vehicle. In it we have brought the themes of versatility and continually changing energy demands to their logical conclusions." The result is a streamlined, lightweight zero-emission car with dramatically reduced energy consumption.

The basic idea behind the 'Rinspeed iChange Concept: The energy demand of a vehicle depends mostly on its weight, the type of engine it uses, and its aerodynamic properties. The engineering-services company Esoro that traditionally builds Rinspeed concept cars has built an extremely lightweight car weighing in at only 1050 kilograms. To power the car, the Swiss specialists chose an electric motor. The idea of the pop-up rear end was conceived to account for the sizeable effect aerodynamics play in fuel consumption.

The energy for the electric motor comes from lithium-ion batteries. The electric motor of the Rinspeed iChange Concept produces 150kW, capable of propelling the car to a top speed of 220 km/h. The sprint from rest to 100 km/h takes just slightly over four seconds. This impressive performance is made possible with the help of a six-speed pre-selector gearbox from the Subaru WRX car. The central research department of Siemens AG (Corporate Technology, CT) supplied the integration technology for engine/generator, electronics and battery connection interface. Siemens has long been one of the world leaders for energy systems and eco technology with pioneering concepts for electric drive systems. Its products cover the entire electric value-added chain from generation to distribution to consumption. The gearbox and drivetrain are lubricated with eco-friendly lubricants from Motorex. Custom-made lightweight 17" and 18" forged wheels with aerodynamic shrouds are supplied by light-alloy wheel specialists AEZ. Pirelli P Zero tires in size 215/40-17 in front and size 245/40-18 in back provide optimal grip.

Rinspeed sQuba Concept, 2008

The 30 years after the movie thriller 'The Spy Who Loved Me' hit the silver screen Rinspeed sQuba is the first car that can actually 'fly' under water.

Zumikon - "Dive it again, James!" If the situation gets too hot for the secret agent he'll go underground - or under water. So demonstrated impressively by Roger Moore in 'The Spy Who Loved Me" in 1977 when he dove below the waves in a sleek vehicle that moments before seemed to be an ordinary car. The only problem: The scene never really took place; it was an animation.

With the Rinspeed sQuba, the world's first real submersible car. The acknowledged James Bond enthusiast and Swiss automobile visionary kept revisiting this scene in his mind over and over.

This submerged stabile flight at a depth of 10 meters that sets the Rinspeed sQuba apart from military vehicles. While the latter can go under water, they are limited to driving slowly over the submerged ground. Rinderknecht: "It is undoubtedly not an easy task to make a car watertight and pressure resistant enough to be maneuverable under water. The real challenge however was to create a submersible car that moves like a fish in water."
