Electric drivetrains fit for hypercars
Integral Powertrain Ltd

If you follow the news of electric hypercars and record breakers, there’s a name that keeps popping up. Integral Powertrain will be supplying the two e-motors, inverters and transmissions for the upcoming Lotus Evija all-electric hypercar, as well as the e-drives on the Aston Martin Valkyrie hybrid hypercar. Integral Powertrain also supplied the motors for the VW I.D. R, which has been racking up a slew of records in recent times, including on the Goodwood and Pikes Peak hill climbs, and around the Nordschleife.

On show at PMW Expo will the company’s SPM motor family, as used in the VW I.D. R. Alongside this will be motors, silicon carbide inverters and an innovative e-axle configuration encompassing inverter, motor and gearbox – all design-optimized for high-performance motorsport applications.

The weight of Integral’s e-Drive motors is extremely low for the torque and power. This is commonly at around 18kW and 23Nm per kilogram. For specific applications this figure can be even higher: a recent product development produced an electric motor with 45kW/kg. In addition, the high CPSR (constant power speed range) of the motors means that single-speed gearboxes can be used while still maintaining superior efficiency across the whole speed range. Integral e-Drive motors typically operate at 99% peak efficiency.
