The iChange concept car uses an iPhone as the ignition to start and stop the car. It is a concept car created by Rinspeed in Switzerland. The car uses a 3D navigation system to calculate eco-friendly routs. The car has a 150 kilowatt Siemens electric motor and can go from 0-62MPH in 4.2 seconds. Looks like it can fit about 3 people in it. It is highly unlikely that this car will be available for purchase to consumers.
The iPhone also controls the turning signals, blinkers, high-beams, and music for the car. Harmon/Kardon speakers are built-in.
