That process is helped by Rivian's new system architecture introduced in the Gen 2 R1 platform last year. This not only greatly simplified the architecture of the vehicles, cutting cost and weight, but it enabled far more finite control over those motors.

Rivian officially introduces its new R1T and R1S Quad models with four internally developed motors together producing 1,025 hp.

Rivian already made the most compelling electric trucks in the world. But the new Quad-Motor versions raise the bar.
