On display at the Geneva motor show, the 1854kg single-seat supercar is for track use only, and packs a 1287bhp, 1725lb ft punch. At 1854kg, the car is 31kg lighter than the Aston Martin DB11, and has a power-to-weight ratio of 694bhp per tonne - over double that of the Aston.
Top speed is claimed to be 205mph, while 0-62mph passes in 3.0sec - the same as a Porsche 911 Turbo. Range is claimed to be around 727 miles from 80 litres of fuel thanks to the diesel-powered turbine range extender, with a 28.4kWh battery pack.
The car can recharge to 80% of this 28.4kWh capacity within 15min when connected to a DC fast charger, and Techrules targets a battery lifespan of 100,000 charging cycles. Diesel is the most efficient fuel, but the Ren is also able to run on gaseous fuels, suggesting the Ren RS will follow suit.
A choice of two powertrain options is available - the car is four-wheel drive, and the entry-level powertrain has two motors powering the front wheels and two for the rear, for combined power and torque of 846bhp and 1150lb ft. The six-motor powertrain, with two motors for the front wheels and four for the rear has 1287bhp and 1725lb ft.
