Rivian’s R2 Drive Unit Brings Major Efficiency Upgrades

Rivian’s R2 is shaping up to be a game-changer, and CEO RJ Scaringe just shared a key upgrade. The new Maximus drive unit uses continuous winding in the stator, cutting welds per stator assembly from 264 (on Enduro) to just 24.

Fewer welds mean faster production, lower costs, and improved reliability—exactly what Rivian needs to make the R2 more affordable. With innovations like this, Rivian is clearly pushing to optimize efficiency while keeping performance high.
