Rivian says its Gen 2 Quad has more than 1,000 horsepower and 1,198 pound-feet of torque. That made scaling up a rocky mound in Lake Tahoe a breeze.

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