Quad Max · Electric· 1025 PS
2025 2025

Four all-new Rivian-designed oil-cooled motors, one per wheel — 764 kW / 1,025 hp peak, 1,198 lb-ft. The Gen 2 Quad replaced the Bosch units entirely with in-house hardware, adding real performance gains rather than just rebadging: +190 hp, +290 lb-ft over Gen1. In-house design also enabled the conserve-mode rear disconnect that the Gen1 Quad couldn't do. 0–60 in 2.5 seconds with Launch Mode — 0.1 sec quicker than the Cybertruck Cyberbeast. ECU count dropped from 17 to 7, wiring harness shed 1.6 miles. The 2025 R1T ran Pikes Peak in a fully stock configuration (race seat, roll cage only) and set the production electric truck record at 10:53.883 — driven by Rivian senior performance test engineer Gardner Nichols. Too new for long-term reliability data beyond the headlight recall 25V-085.

  • !! Headlights fail in cold weather — Recall 25V-085

    Same NHTSA Recall 25V-085 as Tri Motor. Affects early Gen2 production (April 2024 – February 2025). Free control module replacement.

Tri Max · Electric· 850 PS
2025 2025

Three all-new Rivian-designed motors — the first time Quad-class hardware has been replaced entirely by Rivian in-house units. Gen 2 motor architecture is oil-cooled throughout. Combined output 634 kW / 850 hp. No more Bosch assemblies anywhere in the drivetrain. The third motor (rear center) adds torque density without the full complexity of four-corner control. Wiring harness reduced from 1.6 miles to less time under the hood — ECU count dropped from 17 to 7. Max battery: up to 401 miles range, faster DC charging. The Rebelle Rally data that fed into Soft Sand mode updates is baked into the software stack at launch. Early Gen 2 deliveries generated HVAC failure headlines and body quality complaints — typical Rivian launch exposure. Factory warranty: 5 years/60,000 miles vehicle, 8 years/175,000 miles powertrain.

  • !! Headlights fail in cold weather — Recall 25V-085

    NHTSA Recall 25V-085 affects 17,260 R1T and R1S vehicles from 2025. Incorrectly configured headlight control modules from supplier OPmobility may not illuminate on cold startup. Affects vehicles built April 29, 2024 through February 3, 2025. Rivian replaces control modules at no cost.

    Symptoms: One or both low beams fail to light on cold startup

  • !! Drive unit failure — Gen2

    Too early for reliable long-term data. Individual reports of failures on new Gen2 vehicles. Same process as Gen1: complete unit replacement under warranty.

    Symptoms: System warning, power reduction
    4,000–12,000 $
