Rinspeed E2, 2009

What is Rinspeed E2? It is round, small and cuddly, has eyes to fall in love with, a sexy behind - and on demand 60 or 160 hp as necessary. It is Rinspeed's answer to the fast changing requirements of the market and sociopolitical perception about the tuning industry.' Rinspeed boss Frank M. Rinderknecht hits the nail on the head: "Just like the auto industry has to adjust to the demands of a new era, tuners have to look for new ways to do business as well." The Swiss automobile visionary Rinderknecht, who has his roots in the tuning business, observes a change in people's attitude, at least in the western world: "We need an intelligent use of our fossil resources, especially of our energy".

Rinspeed's creation is based on the Abarth version of the Fiat 500. Its name 'E2' signals the fact that the nimble little Italian car is equipped with two different power levels: The 60-hp 'Commuting' level is more than sufficient to move along with city traffic while saving energy. In this mode the Rinspeed E2 consumes just some four liters of fuel per 100 kilometers. Outside the city, the 'Highway' mode provides driving fun and added power for fast and safe passing. In 'Highway' mode the engine produces 160 lively horsepower and transforms the Italian flea into a venerable hornet. Fuel consumption in 'Highway' mode is in the neighborhood of seven liters per 100 kilometers. The energy management system of the Rinspeed E2 is controlled by a small button in the cockpit that affects the engine electronics.

 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.

While other cars always have to ferry around their puffed-up exteriors that can accommodate up to seven passengers even if they're just transporting a single soul, the Rinspeed iChange Concept features an adaptive body. The sole driver is conveyed in a teardrop-shaped car that offers optimal aerodynamic properties and thus minimized energy consumption. If more than one person need to be transported the expanding rear provides room for two passengers. As a result of the increased weight and no longer optimal aerodynamics the energy consumption increases - but only for the time passengers are actually on board.

The energy for the electric motor comes from lithium-ion batteries that are available in two different stack configurations for short- and long-distance driving. 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.
