Rinspeed iChange Concept
From Rinspeed press: The Swiss auto powerhouse Rinspeed presents the ‘iChange,’ 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 "iChange“ 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 gasguzzling behemoths are coming to an end: “The "iChange“ 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 ‘iChange:’: 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 1’050 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 "iChange“ 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.
An initial walk-around reveals that the concept car has no doors. The entire electrically powered roof section of the car measuring just 1.03 meters in height tilts forward to allow passengers to board. Also gone are such mundane things as a key. Its role is filled by an Apple iPhone, which also controls the most important vehicle functions. The "iChange“ is drastically different than ordinary cars in every detail: At the heart of the concept car lies the groundbreaking next-generation Harman/Kardon infotainment system. The system uses an innovative Intel processor technology that guarantees minimized power consumption. The same is true for the Harman/Kardon high-efficiency audio system. This revolutionary technology meets highest demands on sound quality, weighs much less than ordinary systems and at the same time uses only a fraction of energy. This opens the door to a new dimension of energy efficiency. The route guidance of the navigation system is also especially ecofriendly: 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.
