London Motorexpo competition shows future EVs

London's 2012 Motorexpo show has showcased the work of the winners in its competition to design an electric vehicle of the future. The brief, to create a circa 2032 zero-emmission city car capable of transporting four adults and luggage, was won by Michael Vlcek, a first-year student at London's Royal College of Arts' (RCA) Vehicle Design department. Vehicles of the future Vlcek's proposal displayed a car with electric motors mounted in the wheel housings to maximise interior space, and a front-hinged opening to allow access via the rear of the car, where Vlcek positioned the rear lights on vertical vanes to improve aerodynamic stability.
