Although Rivian's R1T truck and R1S SUV are relatively new, the EV manufacturer felt it was necessary to give them some noteworthy enhancements. You'll need to be an extreme Rivian enthusiast to notice visible changes, but there's a lot going on behind the scenes. Updated driver-assist technologies, a new tri-motor powertrain option, a new infotainment system, and a significant power bump for the quad-motor model are all included.

The EV startup now offers two cars with more than 1,000 horsepower. The 835 horsepower quad-motor powertrain is increased to 1,025 horsepower. The R1T's torque output peaks at 1620 Nm when launch control is used, and Rivian reports a 2.5-second 0-100kph run. With two rear motors and one front motor, the tri-motor powertrain produces 850 horsepower and 1370 Nm of torque, which should be more than enough. The two-motor drivetrain is unaltered.

Additionally, batteries have been updated. The regular pack incorporates improved cell chemistry, while certain structural improvements to the Large and Max packs help save some weight. The Max pack's range increases to 675 km from 660 km in the R1T, but some of this can be attributed to a new heat-pump design. To reduce the amount of cable and ECUs needed, the R1 models' core electrical design has also been updated.

Rivian also made adjustments to the R1S's suspension, which was criticized for being a little too rigid and aggressive. It receives updated hydraulic roll-control system calibration, dampers, and springs. Along with new tires to match, both models have new wheel designs. For the quad-motor vehicles, they include Michelin "ultra-high performance" tires.

Rivian's new "Autonomy" platform standard, which includes five radars and eleven cameras for improved driver-assist software and hardware, is available for both the R1S and R1T. Additionally, a future software update will offer autonomous lane change capability to the optional Rivian Autonomy Platform+.
