Porsche 911GT3R Hybrid

Porsche Intelligent Performance – high efficient racing!

Porsche 911GT3R Hybrid

The GT3 R Hybrid utilizes two electric motors to drive the front wheels. Braking energy is

stored in a flywheel. A steering wheel-mounted boost button allows the driver to bring additional

150 kilowatts –204 horsepower – to the front wheels for acceleration.

1 DUAL Inverter for traction motors

2 Portal axle with two e – motors

3 High voltage cables

4 Flywheel storage

5 Inverter for flywheel storage

911GT3R Hybrid: drivetek components

Double-motor, 2×75kW continuous power

high-performance, compact, efficient.

Motors Position Sensor

Position sensor with redundancy for both motors. Only 7mm wide in axial direction.

Each inverter is designed for 75kW continuous power. Total mass 11.5kg.
