With the Paris Motor Show in full swing we take a look at some of the homegrown concept cars that are making the headlines. Renault revealed its super sexy all-electric Trezor concept. Featuring a power unit borrowed from the Renault Formula E team, it boasts 350 brake horse power and can accelerate from 0 to 62mph in under four seconds. Not to be outdone, Peugeot brought along its Fractal concept which has an electric motor on each axle delivering a combined total output of just over 200bhp. Described as an urban coupé, it comes with a removable roof to turn it into a stylish cabriolet. Citroën meanwhile, debuted its new CXPERIENCE petrol-electric plug-in hybrid concept. At just 1.37m tall, the low slung prototype features rear-hinged doors and a concave rear window for improved aerodynamics.
