Renault Twin’Run gets 316bhp & pays homage to the Renault 5 Turbo

The Twin’Run is an extreme version of the next Twingo and manages to pay homage to the old Renault 5, with a thumping great V6 bolted in the middle and pumping out 316bhp and 280lb/ft of torque, enough to get to 62mph in 4.5 seconds and on to 155mph. The Nissan-sourced V6 gets mated to a SADEV six-speed sequential gearbox and comes with a limited slip diff to stop the tyres burning off when the going gets brisk. As well as endowing the Twin’Run with lots of power, Renault has also kept weight down to 950kg by using a tubular chassis, glass-polyester composite for the bodywork, lumps of carbon fibre and not a hugely laden interior.
