Based on the road-going Ren, the Ren RS employs the same turbine-recharging electric vehicle powertrain technology. As a result you can specify the Ren RS with four or six motors (two on the front axle and two or four on the rear axle). The latter motor combination develops 1287bhp and an astonishing 7,722Nm of torque, which yields a 0-62mph time of 3sec and a 205mph V-max.
The powertrain comprises four elements: a turbine, a generator, a battery pack and the electric motors. The turbine burns diesel fuel to drive the generator, which in turn charges up a 28kWh battery pack that supplies power to the electric motors. Brimmed with 80 litres of diesel, the Ren RS has a range of 727 miles.
Fabrizio and Giorgetto Giugiaro have redesigned the Ren’s body with the motosport-biased design brief – and hence aerodynamics – clearly in mind. A new front splitter, aggressive rear diffuser and fixed rear wing now feature on the Ren RS.

However, the biggest exterior change sees the cockpit canopy slimmed down to a slipperier shape, akin to a fighter-jet-style canopy. As a result, the Ren RS only has room for one occupant, not three like the Ren.
The chassis layout is as per the Ren, which debuted at the 2017 Geneva motor show. So aluminum subframes, which house the electric motors and provide the mounting points for the double-wishbone pushrod suspension, are secured to a carbonfibre tub. Continuing the theme of high-grade race-spec componentry are AP Racing carbon-ceramic brakes and KW dampers.
