Based on the GM Ultium platform shared with the Hummer EV, the Sierra EV will launch as an innovative, premium six-figure pickup truck. Over time, GMC will introduce lower trims at more attainable prices, descending to a $50,000 base price. The Denali Edition 1 boasts 754 hp. GMC says the crew cab truck can launch from 0-60 mph in under 4.5 seconds and achieve an estimated 400-mile range. The unified bed and body allows a midgate to open up into the cab, extending enclosed cargo space from a 5-foot 11-inch bed to 9 feet. Other clever features include crab walk, allowing the truck to move diagonally at low speeds, and all-wheel steering, enabling a tight turning circle. The Denali Edition 1 and the off-road focused AT4 come with a towing-compatible version of the Super Cruise hands-free driver assistance technology. For 2025 two Denali versions are offered: an Extended Range with 645 hp and 390 miles of range; and a Max range with 754 hp and 460 miles of range.
