“…a perfectly engineered high-performance track car…”William Jin, Founder and CEO, Techrules
The drivetrain can be configured with either four or six axial flux, liquid-cooled electric motors manufactured by YASA in the UK. The four-motor set-up will drive all four wheels while the highest-power six-motor configuration has two motors for each rear wheel, and one for each front wheel. The four motors will produce 858 hp and 1,150 lb-ft of torque and the six motors will generate 1,287 hp and 1,725 lb-ft of torque and has a range of 1,170 km from 80 litres of diesel fuel. With its one forward gear, the Ren RS can accelerate from 0-100 km/h (0-62 mph) in 3 seconds and has a top speed of 330 km/h (205 mph). The car weighs in at 1,854 kg or 4,087 lbs.
The aerospace-inspired design of the 2017 Ren supercar was developed by world-renowned automotive designers, Fabrizio and Giorgetto Giugiaro, with a unique three-seat Le Mans-style configuration. The new Ren RS has been developed further by L.M. Gianetti to create the more driver-focused single cockpit layout beneath the distinctive fighter jet-style canopy, which rises from the centre of the car to allow driver access.
Inside, the driver sits comfortably in a protective carbon fibre race seat, manufactured by OMP to FIA-approved standards. To comply with FIA regulations, a fire extinguisher and six-point harness are also included.
“With electric vehicles, an electric motor is used to drive the wheels, which effectively frees the combustion engine to exclusively convert chemical energy into mechanical energy and finally into electric energy,” said Matthew Jin, Techrules Chief Technology Officer. “This is a major breakthrough, making it possible for us to use the highly efficient turbine engine as a superb range extender on our vehicles.”
Techrules first presented its TREV technology at the 2016 Geneva Motor Show in its GT96 and AT96 concept cars. The ground-breaking range extender system uses a turbine to drive a generator which charges the battery pack. This provides electricity to drive the traction motors. Unlike many previously developed turbine powertrain systems, there is no direct electrical feed from the generator to the electric motors in normal operation. Only when the battery is depleted can the turbine be used to propel the car.
The 28.4 kWh battery packs installed in the two lateral pods are designed and manufactured specifically for the Ren RS and incorporate battery management technologies that enable superior charging efficiency and power balancing between battery cells. The battery management system (BMS) is integrated and designed to optimise the performance and life of the battery while ensuring absolute safety. There are three water cooling circuits for the motors, battery and inverter. A heat exchanger (radiator) pack is attached to the front aluminium chassis plate and the cooling circuits are supplied by six electric pumps also mounted on the front plate.
The Ren RS will be available for track use only and will begin customer deliveries within two years.
