THE 2026 GMC SIERRA EV AT4 SURPRISED ME ON AND OFF-ROAD!

EV Channels Review

The 2026 GMC Sierra EV AT4 presents a compelling, albeit not perfect, entry into the electric off-road truck segment. The reviewer highlights its impressive 725 horsepower, substantial 205 kWh battery, and a respectable real-world efficiency of 2.5 miles per kWh on the highway. Off-road capabilities are bolstered by a 35-inch Goodyear Wrangler Territory AT tire, a slightly higher ride height than other Sierra EVs, and unique Terrain and Off-Road drive modes that significantly alter the driving dynamics. The reviewer praises the Super Cruise system for its advanced navigation integration and ease of use, even while towing. However, notable drawbacks include the absence of a spare tire and the lack of a mechanical rear locking differential, relying instead on brake-based torque vectoring. The fixed-height coil suspension, while durable, offers a firmer ride than some might expect, with some harshness over bumps and expansion joints. Despite these points, the initial impression is overwhelmingly positive, positioning the Sierra EV AT4 as a competitive and capable electric truck within its price range.
