The Rivian quad motor R1T and R1S models pack a formidable 1,025 horsepower and 1,198 lb-ft of torque, thanks to four independently controlled in-house motors powered by a 149 kWh battery. According to MotorTrend’s September 2024 testing, the R1S accelerates from 0–60 mph in just 2.6 seconds, making it the fastest SUV they’ve ever tested, beating traditional high-performance SUVs by over a second, such as the BMW XM and GLS63 AMG.
Quarter-mile sprints clock in at 10.5 seconds at 128.2 mph, while a 60–0 mph stop takes 107 feet, outperforming dual- and tri-motor R1 variants. Although these models weigh a hefty 6,824 lbs, the Rivian quad motor setup still deliver a 0.88 g skidpad and a 25.1-second figure-eight lap, showcasing exceptional composure in a nearly 7,000-pound SUV.
Even more remarkable, these innovations come via Rivian’s second-generation hardware: proprietary motors, upgraded software, zonal wiring saving 1.6 miles of cable and cutting 20 kg of weight—a move reducing carbon footprint and costs by ~15–20%.
Kick Turn: Tactical Precision in Off‑Road Maneuvering
The new “Kick Turn” feature, formerly dubbed “Tank Turn,” provides controlled on-the-spot rotation by spinning inside wheels in reverse while the others drive forward. It’s far more than a stunt: drivers can regulate rotation speed via accelerator and steering-wheel buttons, and a 20-second limit safeguards the environment and drivetrain integrity.
Rivian’s enhanced zonal electronic architecture and in-house motors deliver millisecond torque-vectoring accuracy, crucial for slippery or uneven terrain. The feature will be available via an OTA “Kick Turn” update this fall, along with a “RAD Tuner” that offers customizable drive modes and adaptive dynamics settings.
Halo Strategy Backed by Robust Specs and Practical Features
The Rivian quad motor variants, positioned as “halo” models, start at $115,990 for the R1T and $121,990 for the R1S, while Launch Edition trims with exclusive features—like “Launch Green” paint, upgraded interiors, and additional tech—start near $125,990. Rivian confirms deliveries begin later this month.
Despite the impressive performance, efficiency trade-offs are notable: EPA estimates indicate up to 374 miles of range in Conserve Mode and around 338–360 miles in Launch Editions, while real-world EPA combined range drops to 274 miles in spirited driving. Charging peaks at 220 kW, taking about 55 minutes to go from 5% to 80% battery—adequate but slower than some rivals.
Rivian CEO RJ Scaringe has termed these hyper-capable Rivian quad motor models an “exercise in unnecessary capability,” aimed at showcasing brand innovation and attracting attention, even though affordable volume depends on the forthcoming $45,000 R2 platform and expanded Rivian Adventure Network chargers.
In sum, Rivian’s second-gen quad-motor R1T and R1S deliver supercar-beating acceleration, torque-vectoring control, and off-road tactility, wrapped in a halo package that bolsters brand prestige. With OTA-enhanced features like Kick Turn and customizable drive tuning, these Rivian quad motor models represent Rivian’s bold push into elite EV territory, while setting the stage for broader market growth.
