Electric GMC Sierra EV Efficiently Towed a 3,500-pound Boat 116 Miles, Leaving 54% Battery Remaining, Showcasing Capability of Electrified Vehicles for Demanding Tasks
2025 GMC Sierra EV Denali Extended Range: Impressive Towing Capabilities and Efficiency
The 2025 GMC Sierra EV Denali Extended Range has made a significant impact in the electric pickup truck market, showcasing impressive towing capabilities and practicality.
With a tow rating of 10,500 pounds, the Sierra EV Denali Extended Range matches GM's highest trailering rating for the Sierra EV lineup. In a real-world test, David Kuperberg towed a 3,500-pound boat for 116 miles, leaving the truck with 54% battery remaining without the need for a recharge [1].
For those seeking a more range-focused option, the Max Range pack offers a slightly smaller battery (170 kWh compared to the Extended Range's 170 kWh) and a towing capacity of 10,000 pounds. However, the Extended Range pack provides an additional 500 lbs of towing capacity, offering extra flexibility under heavier loads [1].
Both versions come equipped with GM's ProGrade Trailering System, which includes features such as Hitch Guidance, trailer light testing, custom trailer profiles, and multiple camera views to assist with towing safety and convenience [1][2].
While towing large loads can slightly reduce driving range, real-world tests show that towing roughly 9,000 lbs at highway speeds can reduce the Max Range pack’s estimated 460 miles down to about 440 miles, with similar proportional impact expected for the Extended Range pack [1].
The Sierra EV handled the tow with great efficiency, starting with a 100% charge and ending with an 81% State of Charge (SOC) and a 203-mile range [1]. The truck's Super Cruise feature also managed stop-and-go traffic with ease during the tow.
Other Sierra EV and Silverado EV owners have reported similar successful towing experiences, with one user even stating that their RSX Silverado EV tows routinely and performs better than a Ford 450 Diesel [1].
The Sierra EV's spacious interior offers generous rear accommodations: 38.7 inches of headroom, 44.3 inches of legroom, 63.3 inches of shoulder room, and 60.8 inches of hip room. The front cabin dimensions are equally impressive, with 43.9 inches of headroom, 44.8 inches of legroom, 64.0 inches of shoulder room, and 61.3 inches of hip room [1].
David Kuperberg's Facebook post documented the tow, and his post highlighted a shift in mindset, expressing that the Sierra EV's performance addressed his previous hesitation about electric trucks compared to internal combustion engine trucks [1]. Another user mentioned achieving 1.4 miles per kWh while towing a 2,000-pound trailer [1].
The present state of electric pickups is defined by the ability of a 9,000-pound electric pickup to perform tasks previously dominated by diesel dually trucks, marking a significant milestone in the electric vehicle revolution.
