Rinspeed iChange Concept

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.
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 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 route guidance of the navigation system is also especially eco-friendly: The system calculates the most energy-saving route and displays the directions in realistic 3D view. Eberspächer Group from Esslingen, Germany is one of the world leaders in car heaters. Specifically for the „iChange" project Eberspächer developed custom-tailored electric and fuel-burning heating systems. Both systems are geared toward the specific requirements and conditions of electric vehicles.

The pure wool used in the interior was further refined into high-tech wool by Schoeller using state-of-the-art processes. The wool is spun and died in accordance with the highest eco standards. It provides an extremely extravagant ambiance in the Rinspeed iChange Concept, looks stunning and is delicate to the touch. The competence partner Strähle + Hess transformed this natural product into a striking interior.

The Swiss Federal Ministry for Energy (Bundesamt für Energie) supports the „iChange" project as a groundbreaking research and development project. Solar panels on the top and sides of the roof provide electricity to the fan to keep temperatures in the Rinspeed iChange Concept comfortably low on hot summer days. The large Sharp solar panels also provide additional eco-friendly charging of the batteries.

With the Rinspeed iChange Concept Rinderknecht, a passionate C. F. Bucherer watch wearer, and his partners once more want to provide food for thought for the automotive industry. The Swiss car visionary: "If we want to maintain our individual mobility in the future we have to rethink the car in its entirety, without taboos. Most of all, we have to take its ecological aspects into consideration." And in the end everyone has to personally answer the same question: Am I ready and willing to change myself, do and can 'I change'?
