Lucid details the drivetrain on the Lucid Air, will present the vehicle on September 9Lucid Motors has unveiled details of its proprietary, in-house developed electric drivetrain that will power the forthcoming pure-electric luxury Lucid Air the production version of which will be unveiled on September 9 along with available configurations and pricing.

The Lucid Air will have a dual-motor AWD system with 1,080 hp output for quarter-mile times as low as 9.9 seconds on a consistent, repeatable basis. To date, it is the only electric sedan able to achieve a quarter-mile time under 10 seconds. The power of the Lucid Air is complemented by an available extended-range capability that achieves an estimated EPA range of up to 517 miles on a single charge.

Lucid has been able to create powerful, compact, and ultra-efficient permanent magnet electric motors which together with an inverter and an integrated transmission and differential create a state of the art, 900V+ electric drive unit that weighs just 163lb (74kg) and is small enough to fit inside a standard airline carry-on roller bag. Each drive unit packs over 650hp, with a power density that is well beyond anything else offered on the EV market at 41hp per liter. This compactness allows for one, two, or even three units to be used to power a Lucid Air. In total, Lucid's drive units are 45% lighter and up to 59% more powerful than the closest competitor. For their power, the motors are two and a half times more volumetrically compact than the closest competitor. Also notable is the fact that the motors can spin up to 20,000 rpm, a significant performance advantage over the competition.

Lucid has achieved this through a number of innovations, including a new motor winding technology to maximize power output and reduce electrical losses. The motor also features an innovative cooling system that more effectively removes heat from the stator winding, minimizing losses and boosting efficiency. Meanwhile, Lucid leverages a high voltage, silicon-carbide MOSFET system in its inverters to maximize efficiency, especially in real-world driving conditions.

An ultra-high, 900V+ architecture combined with Lucid's Wunderbox onboard charging unit serve as the heart of the Air's electrical platform. The Wunderbox is a unique, multi-function unit, developed entirely in-house to ensure compatibility with, and the maximizing of, charging systems of differing voltages, specifically boost-voltage charging. It also allows the Lucid Air to charge at rates of up to 300 miles in 20 minutes and up to 20 miles in one minute when connected to a DC Fast Charging network (such as those offered by Lucid's charging partner, Electrify America, on its nationwide network). The Wunderbox also enables a wide array of future-ready, bi-directional power delivery features from the vehicle to the grid (V2G) for situations such as managing home power outages. It can also enable vehicle to vehicle charging (V2V).
