based on driving range, acceleration, and connected features. However, it's equally important to focus on the drive system since that component is critical to determining how powerful a car will be. Automakers often provide buyers with more than one option. Although tri-motor and quad-motor powertrains are significantly more expensive compared to single and dual-motor choices, they offer the best driving experiences.
Rivian buyers can choose from three all-wheel-drive (AWD) configurations. They include Dual-Motor AWD, Dual-Motor Enhanced AWD, and Quad-Motor AWD. Despite their differences, both the Dual-Motor and Quad-Motor systems are built to supply on-road and off-road adventures. Rivian’s Dual-Motor system features two single-motor drive units that send power straight to the EV, while the Quad-Motor AWD combines two drive units with an autonomous motor for each of the four wheels.
Rivian AWD Systems Compared
While Dual-Motor is a standard feature, drivers need to shell out $8,000 to get the Quad-Motor AWD. When it comes to performance, the Rivian Quad-Motor AWD outshines the Dual-Motor AWD, but there are still a few things about the latter to consider. While the Dual-Motor AWD can deliver a max output of 600 horsepower and 600+ lb-ft of instant torque, the Quad-Motor drive system promises a combined output of 835 horsepower and 908 lb-ft of torque. The Dual-Motor AWD can accelerate from 0-60 mph in 4.5 seconds, but it's not enough to outdo the Quad-Motor’s record of 3 seconds.
Another factor that places the Quad-Motor system ahead of its counterpart is independent torque vectoring. This refers to the proficiency of each wheel to autonomously help with acceleration and deceleration. Additionally, each wheel can turn the vehicle thanks to this feature which guarantees the greatest standards of on-road performance and off-road power. Meanwhile, the Dual-Motor AWD does offer torque vectoring (front to rear) but not with the same self-sufficiency as the Quad-Motor option. The third AWD system, Enhanced Dual-Motor, is another option to consider for those who want more power without paying for Quad-Motor. It offers a faster acceleration time of 3.5 seconds, 700 horsepower, and 700 lb-ft of torque.
Based on their respective capabilities, the Quad-Motor AWD is the clear winner. For those interested in equipping their R1S or R1T with the Quad-Motor option, only the large battery pack is currently available. It costs an additional $6,000 and should turn the EV into a backup power source, just like the Ford F-150 Lightning. Rivian says Enhanced Dual-Motor AWD will be added as an option in early 2023, but pricing is yet to be announced.
