The Rivian R1S Large Pack, equipped with a 135 kWh battery and quad-motor all-wheel drive system producing 835 horsepower, represents the flagship configuration of Rivian’s all-electric SUV. Introduced in 2022, the R1S is Rivian’s entry into the premium SUV segment, directly competing with vehicles like the Tesla Model X, Mercedes-Benz EQS SUV, and Cadillac Lyriq. It builds upon the “skateboard” battery platform shared with the Rivian R1T pickup truck, prioritizing both on-road comfort and substantial off-road capability. The R1S is notable for its spacious seven-passenger seating, advanced technology, and focus on sustainable materials.

Powertrain & Engine Architecture
The R1S Large Pack utilizes a fully electric powertrain, eschewing the internal combustion engine entirely. Its core is a 135 kWh lithium-ion battery pack positioned low in the vehicle’s chassis, contributing to a low center of gravity and improved handling. This battery powers four independent electric motors – one for each wheel – enabling true all-wheel drive capability and precise torque vectoring. Each motor is a synchronous design, chosen for its efficiency and power density. The combined output of these motors is 835 horsepower and 907.94 lb.-ft. of torque. Rivian employs a sophisticated thermal management system to regulate battery temperature, optimizing performance and longevity. The single-speed automatic transmission is integrated directly into each motor, simplifying the drivetrain and maximizing efficiency. The 400V architecture allows for relatively fast DC fast charging, though charging times vary depending on the charger’s output.
Driving Characteristics
The quad-motor configuration of the R1S Large Pack delivers astonishing acceleration – 0 to 60 mph in approximately 3 seconds. The instant torque available from the electric motors provides a responsive and engaging driving experience. The air suspension system, standard on this trim, offers adjustable ride height, allowing for both comfortable on-road cruising and increased ground clearance for off-road adventures. The torque vectoring system enhances stability and agility, particularly in challenging conditions. Compared to potential future lower-trim R1S models with smaller battery packs or fewer motors, the Large Pack offers significantly greater range and performance. The single-speed transmission provides seamless acceleration, though it lacks the gear changes found in traditional automatic transmissions. The R1S feels substantial in size, but the precise steering and responsive handling make it surprisingly manageable.
Equipment & Trim Levels
The R1S Large Pack is positioned as the premium offering in the R1S lineup. Standard equipment includes the aforementioned air suspension, a large touchscreen infotainment system with over-the-air update capability, a panoramic glass roof, premium vegan leather upholstery, heated and ventilated front seats, and a comprehensive suite of advanced driver-assistance systems (ADAS) including adaptive cruise control, lane keeping assist, and automatic emergency braking. Optional extras include a third-row seating configuration (increasing passenger capacity to seven), a powered frunk (front trunk), and a premium audio system. Rivian offers a high degree of customization, allowing buyers to select from a range of interior and exterior colors and finishes.
Chassis & Braking
The R1S utilizes a robust chassis designed to handle both on-road and off-road demands. The independent suspension, featuring double wishbones at the front and a multi-link setup at the rear, is paired with the adjustable air suspension. This combination provides a comfortable ride and excellent wheel articulation for off-road traversal. Ventilated disc brakes are fitted to all four wheels, providing ample stopping power. The anti-lock braking system (ABS) and electronic stability control (ESC) further enhance safety. The R1S’s relatively high weight (5842.25 lbs) is mitigated by the low center of gravity afforded by the battery pack’s placement.
Market Reception & Comparison
The Rivian R1S has been generally well-received by automotive critics, praised for its innovative technology, luxurious interior, and impressive performance. Its range of 311.93 miles on a single charge is competitive within the premium electric SUV segment. Compared to the Tesla Model X, the R1S is often lauded for its more refined interior and superior off-road capability. However, the Model X benefits from Tesla’s extensive Supercharger network. The R1S’s price point places it firmly in the luxury segment, and its initial production ramp-up experienced delays, impacting availability. Reliability data is still emerging, given the vehicle’s relatively recent introduction, but early reports suggest a generally high level of build quality.
Legacy
The Rivian R1S Large Pack represents a significant step forward in the electric SUV market. Its combination of performance, luxury, and off-road capability sets it apart from many competitors. The vehicle’s innovative design and focus on sustainability are likely to influence future electric vehicle development. As Rivian expands its production capacity and service network, the R1S is poised to become a prominent player in the premium SUV segment. The long-term reliability of the quad-motor powertrain and battery pack remains to be seen, but Rivian’s commitment to over-the-air software updates suggests a proactive approach to addressing potential issues and improving vehicle performance over time. On the used car market, early R1S models are holding their value well, reflecting the strong demand and limited supply.
