How does Rivian towing capacity stack up compared to other options on the market? The towing capacity of the Rivian truck comes courtesy of three powertrain options for the 2026 model year, namely, Dual-Motor, Tri-Motor, and Quad-Motor. The Rivian SUV towing capacity is delivered through the same Dual, Tri, and Quad-Motor configurations. However, the SUV’s maximum towing capacity of 6,000 lbs is significantly lower than the Rivian R1S’s 7,700 lbs. When equipped with the AWD powertrain and towing package, the Kia EV9 has a maximum towing capacity of 5,000 lbs.
