Renault TwinRun hot hatch concept (2013) first official pictures

Renault will show off this mid-engined supermini concept at the 2013 Monaco Grand prix race weekend. Called the TwinRun, the R5 Turbo-inspired creation is powered by a mid-mounted 3.5-litre V6, and will hit 155mph flat out. The TwinRun is the latest in a series of wacky Renault concept cars, following the Twizy RS F1 and Twin-Z supermini into the limelight.

Meanwhile, this first tuned and tweaked version of the A1 uses the same engine as the VW Polo GTI, Skoda Fabia vRS and Seat Ibiza Cupra.
