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

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.

The Rivian R1T would like to tell everyone that there's only one sheriff in town, and it's got four electric motors.
