Electrical automobiles have come a good distance. As soon as nothing however standing symbols for folk attempting to make a degree about local weather change, they finally become kings of the drag strip due to their neck-breaking torque and superior acceleration. There’s all the time room for enchancment, although, particularly in a world so closely weighed down by batteries. Now, Lucid Motors has a plan for that.
The EV startup revealed its newest electrical motor that packs a critical punch in a really tiny bundle. Weighing in at 70.5 kilos and producing 469 horsepower because it spins as much as 19,500 rpm, the tiny unit has discovered its dwelling as the usual drive unit contained in the nosecone of each automobile in “the world’s main single-seater electrical racing collection”—higher often known as Formulation E.

I do know what you are considering—what in regards to the different items wanted to finish a drive unit just like the single-speed transmission, differential, and inverter? Nicely, that is all included within the 70.5-pound official determine, which makes this all of the extra spectacular.
Lucid can also be no stranger to Formulation E. Actually, the electrical automaker provided the battery system for Formulation E’s Gen 2 automobiles, although Williams Superior Engineering took the torch for the Gen 3 automobiles. At this time’s announcement was a tongue-in-cheek means of claiming that they are again, this time manufacturing simply the entrance drive unit for the Gen 3 automobiles. It is also a delicate reminder that its engineers know learn how to pack some critical energy in a small bundle, proving that it isn’t the scale of the motor that counts.
The Drive was capable of affirm the precise measurements of the unit, revealing that it is just 10.2 inches broad, 10.5 inches tall, and 13.5 inches lengthy—that means that it will probably slot in practically the identical house usually occupied by a big differential.
For comparability, the efficiency drive unit from a Tesla Mannequin S or X weighs 290 kilos, in line with Stealth EV. These items, which are available a considerably bigger bundle, produce as much as 536 horsepower, or round 1.85 hp/lb, or 645 hp within the so-called Ludicrous fashions. The Tesla Mannequin 3 drive unit is barely smaller than the Mannequin S and X, although nonetheless bigger than Lucid’s and weighs round 200 kilos. This unit produces round 283 hp, or 1.4 hp/lb. Lucid’s drive unit is packaged considerably extra compact and dials in at a decent 7.1 hp/lb.
It is value noting that these business drive items serve a distinct objective than Lucid’s new Formulation E motor, and are seemingly constructed to completely different requirements—you have obtained consumer-facing autos that want longevity and on-road reliability, versus a purpose-built racing equipment that should shave off kilos and take fairly a little bit of abuse throughout a race.
Regardless of the completely different wants, the motor really makes use of some tech from the Lucid Air street-going automobile. The automaker says that its racing drive unit makes use of the identical high-voltage steady wave winding within the motor’s development, plus the identical microjet cooling system because the Air. Peter Rawlinson, CEO and CTO of Lucid, says that he believes that among the new tech discovered within the racing motor will finally trickle all the way down to Lucid’s highway automobiles sooner or later—simply because it does with many different automakers.
