Peugeot The iOn is a two-door car with four seats that is only 2.5m long – the four seats have been made feasible with some clever packaging that includes seats that provide just the basic backrest, a bit like a motorbike. The iOn is based on the Mitsubishi i-Car, has an electric range of 75 miles and will go on sale in 2010. www.peugeot.com
