GMC has unveiled the 2024 Sierra EV Denali, the third all-electric truck in its lineup following the Hummer EV pickup and SUV. Sharing the Ultium platform with the Hummer EV and 2024 Chevrolet Silverado EV, the Sierra EV will launch in early 2024 as a fully loaded Denali Edition 1 trim available in limited numbers.
Reservations open today for this particular model, which has a starting MSRP of $107,000 (plus an estimated destination shipping fee of $1,695). That said, the GMC Sierra EV lineup will add more affordable models for the 2025 model year, the Elevation and AT4, with the former starting around $50,000.
Back to the Sierra EV Denali Edition 1, it offers a GM-estimated range of 400 miles (640 kilometers) on a full charge, but GMC is not yet willing to reveal the battery capacity. When asked about it during a livestream briefing InsideEVs attended, GM Battery Electric Trucks chief engineer Nichole Kraatz said the Sierra EV shares “similar batteries to the Hummer EV,” without providing details.
The battery, which is also a structural element of the vehicle, powers a dual-motor drivetrain that delivers 754 horsepower and 785 pound-feet (1,063 Newton-meters) of torque via an e4WD system in Max Power mode. An interesting detail Kraatz revealed during the walkthrough is that the Max Power mode is available as long as the driver wants, making it different from the Hummer EV’s Watts to Freedom mode, which allows for maximum torque only for a short time.
Engaging Max Power results in 0-60 mph acceleration in less than 4.5 seconds, making the Sierra EV Denali the fastest Sierra ever. Max Power is one of five customizable driving modes, in addition to Standard, Tow/Haul, Off-Road and My Mode.
Another strong point of the GMC Sierra EV Denali Edition 1 is the 800-volt electrical architecture that enables DC fast-charging capacity of up to 350 kW, which allows about 100 miles (161 kilometers) of range to be added in just 10 minutes. The electric truck also includes a 19.2 kW onboard AC charging module for home and public charging, in addition to offering access to GM’s Ultium Charge 360.
As expected, the 2024 GMC Sierra EV uses many of the features introduced by the Hummer EV, such as 4-Wheel Steer, CrabWalk, Variable Regen on Demand Braking, One-Pedal Driving and Air Ride Adaptive Suspension.
It also comes with Power Station Pro bi-directional charging, which allows the truck to be used as a mobile power source in various situations. For example, with the available Ultium Power Bar accessory, the 2024 Sierra EV offers 10.2 kW of off-board power through up to 10 outlets that can help power tools and other accessories on the trail or at a campsite. When properly equipped, the Power Station Pro can also power another electric car and even a home – for up to 21 days combined.
When it comes to practicality, GMC says the Ultium platform provides “unparalleled flexibility and versatility for transportation and cargo storage never before available in a Sierra.”
As with the 2024 Silverado EV, the Sierra EV Denali Edition 1 will be offered exclusively as a Crew Cab model with an integrated 5-foot, 11-inch (1.80-meter) cargo bed. The MultiPro Midgate provides 9 feet (2.74 meters) of storage between the cab and tailgate when open, or nearly 11 feet (3.35 meters) when the standard MultiPro tailgate is down.
An available tonneau cover turns the bed into a second lockable weatherproof compartment after the roomy front eTrunk, which has two drains and a 120-volt power outlet.
Inside the cabin, the flat floor allows for more storage space, including a modular center console, while the second-row 60/40-split seat offers four configurations. In terms of towing, the 2024 Sierra EV Denali Edition 1 has up to 9,500 pounds (4,309 kg) of towing capacity and up to 1,300 pounds (590 kg) of payload. A trailer package is standard on the Denali Edition 1.
GMC’s luxury sub-brand is well represented by the Sierra EV Denali, which features a fixed panoramic glass roof that extends above both rows of the cabin, a new rich quilting pattern inspired by the vehicle’s bold front, and premium materials such as leather, authentic open-pore wood, aluminum and even etched stainless steel.
The Denali is also all about technology and the Sierra EV does not disappoint in that regard either. It features a smartphone-like 16.8-inch free-form infotainment touchscreen — the largest ever in a Sierra — along with an 11-inch reconfigurable Driver Information Center and a multi-color Head Up Display powered by GM’s Ultifi vehicle software platform.
The Sierra EV Denali also gets up to 14 available camera views to improve visibility around the vehicle, Hands-Free Start and Super Cruise hands-free driver assistance technology, which works even when towing.
The Denali Edition 1 will be built at GM’s Factory ZERO Detroit-Hamtramck Assembly in Michigan, but future Sierra EVs will also be assembled at the Lake Orion plant in the same state.
