Rinspeed iChange Concept
Rinspeed iChange Concept is the world’s first car whose body adapts to the number of passengers on board, it is more than just a clever concept car. 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.
When push of a button the rear end of the teardrop-shaped car magically pops up, in seconds a streamlined one-seater sports car transforms into a comfortable car with ample room for three.
Rinspeed claimed have designed and built an extremely flexible vehicle. Interior 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.
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 iChange’s 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 „iChange“ 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.
