EV Channels Review
The 2026 GMC Sierra EV AT4 trim offers a compelling blend of off-road styling and capability, though it stops short of being a hardcore off-roader. While it boasts a 2-inch lift, 35-inch all-terrain tires, and enhanced skid plates, its true off-road prowess is somewhat limited by the lack of locking differentials and disconnecting sway bars. The reviewer highlights the impressive on-road comfort and quietness compared to previous iterations, and praises the massive 217 kWh battery pack offering exceptional range (476 miles estimated) and fast charging (up to 380 kW). Key criticisms include the continued use of a CCS charge port instead of NACS, the lack of a 'dog mode', and the artificial EV motor noise piped into the cabin when full power is engaged. The rear charge port is also noted as inconvenient for towing. Despite these drawbacks, the AT4's standard features, spacious interior, and the overall capability of the Sierra EV platform, particularly its towing and range, make it a strong contender, especially for those prioritizing a comfortable and capable electric truck for work or outdoor adventures.
