What It Is
The Rivian R3X is an upcoming high-performance electric crossover SUV from the American EV startup Rivian. It is based on the R3 midsize SUV platform and will be positioned as the top-tier performance variant.
Why It Matters
The R3X represents Rivian’s foray into the lucrative high-performance electric SUV segment, competing with models like the Tesla Model X Plaid and upcoming rivals from legacy automakers. Its performance credentials and Rivian’s adventure-focused branding could appeal to buyers seeking an electrified alternative to gas-powered performance SUVs.
Structural Design and Lightweight Engineering
Rivian’s R3X features an innovative three-layer side panel structure, enhancing the strength around the door frames while utilizing a hollow design to reduce weight. This lightweight yet robust construction contributes to improved range and overall vehicle efficiency.
Powertrain and Dynamics
The R3X incorporates an advanced four-motor setup, with a compact 415 hp unit driving the front axle and a higher-torque 420 hp unit at the rear, delivering a combined output of over 800 hp and 900 ft-lbs of torque. This configuration enables precise torque vectoring for optimal traction and handling across various terrains, from high-speed cornering to low-speed rock crawling. The vehicle can accelerate from 0-60 mph in just 3 seconds and reach 100 mph in 7 seconds, while boasting an impressive 11,000 lbs towing capacity.
Skateboard Platform and Suspension
The R3X is built on Rivian’s innovative skateboard platform, which houses the battery pack, drive units, suspension, brakes, and thermal systems below the wheel level. This architecture lowers the center of gravity, enhancing stability and agility. The suspension features unequal-length double wishbones in the front and a multi-link setup at the rear, complemented by dynamic roll control, adaptive dampers, and an adjustable air suspension for optimized on-road comfort, performance, or off-road capability.
Battery and Range
The R3X offers three range options: 250 miles, 314 miles, and 400+ miles, powered by a 392V high-voltage battery pack. The battery management system incorporates advanced cooling techniques, with a cooling plate between each pair of cylindrical 2170 lithium-ion cells for optimal thermal management.
Innovative Features and Functionality
The R3X boasts ample storage spaces, including a front trunk, a gear tunnel beneath the cargo bed, and a vast underfloor compartment for outdoor equipment like fishing rods and camping gear. It also features a tank turn mode (enabled by the four-motor setup) and a comprehensive suite of driver assistance systems, including 11 cameras, 5 radars, and 12 ultrasonic sensors.
Pricing and Availability
Rivian has not announced pricing for the R3X, but it is expected to carry a significant premium over the standard R3 models, which could start around $45,000. Production is slated to begin in 2026 after the launch of the R2 and R3 models.
With its cutting-edge engineering, impressive performance capabilities, and innovative features tailored for adventure enthusiasts, the Rivian R3X is poised to redefine the electric vehicle landscape, particularly in the pickup truck and SUV segments.
