In 2009 McLaren Applied Technologies was tasked with developing the electric drive system for the McLaren P1 supercar. Key to the requirements of the world’s first hybrid supercar was that the addition of an electric drive system must improve the car’s performance on the racetrack and this demanded power-to-weight ratios that were only just starting to be seen in Formula 1 KERS systems.
McLaren Applied Technologies took on the challenge of developing an E-Motor, Motor Control Unit (MCU) & 14V DC-DC Converter capable of bringing unrivalled performance advantage to the road.
When the McLaren P1 went into production four years later McLaren Applied Technologies had established a strong position as a supplier of automotive-qualified electric drive systems. The E-Motor and MCU-500 used in the P1 provides up to 120 kW of mechanical output power with a total mass of 42 kg. This includes an integrated 14V DC-DC converter – subtracting the weight of this device, the MCU-500 is capable of delivering more than 20 kW/kg. The E-Motor produces approximately 4.5 kW/kg.
Our E-Motor reduces fuel consumption while providing instant torque, and was used by all Formula E teams, demonstrating the fluid transfer and application between our motorsport and automotive technology. Further development of the system resulted in the E-Motor achieving more than 7 kW/kg.
