Novelties in the motorsport propulsion: the American Lucid Motors has just unveiled its innovative electric motor for motorsport, which already equips Formula E cars as a standard front power unit.
Peter Rawlinson, CEO and CTO, Lucid Group, declared: «With incredible power density of 14.7 hp/kg and immense energy recuperation, this drive unit will once again transform electric motorsports, following in the footsteps of our revolutionary battery pack in prior race seasons. This new motorsports drive unit builds directly upon the groundbreaking powertrain technology developed in-house by Lucid and proven on the road in every Lucid Air. I’m excited by the prospect that some of the technical advancements introduced may in turn make their way to future Lucid road cars».
The new propulsion system can then supply 476 HP of power and is composed by motor, inverter, differential and transmission, everything for an overall weight of 32 kg. The rotor reaches a maximum speed of 19,500 rpm and an advanced high-voltage continuous-wave winding and an exclusive microjet cooling system are present.
There is already some literature about that: the new traction unit, positioned in the front part of Gen3 single-seaters of Formula E, allows recovering energy from front wheels while braking, notably increasing performances and efficiency.
