Renault Twin’Z Concept previews 2014 Renault Twingo

The Renault Twin’Z Concept, designed by British designer Ross Lovegrove, is an electric city car previewing the 2014 Renault Twingo. The Renault Twin’Z Concept is a small, just 3623mm long, urban runaround with a small electric motor good for 67bhp and 167lb/ft of torque  and weighing in at 980kg, complete with a fairly sophisticated double wishbone suspension and relatively long wheelbase with a wheel at each corner stance. The Twin’Z is very much a concept car - designed by British designer Ross Lovegrove – and comes complete with the usual concept fripperies like electric suicide doors, cameras instead of rear view mirrors, sweeping LED lights, a solid crystal rear spoiler and big, complicated alloys.

The top five sellers all eclipsed the magical million-dollar figure with the auction broadcast live on Speed TV.
