Buy a truck that can pull weight for your workday needs and reduce carbon emissions. The 2025 GMC Sierra EV is a revolutionary pickup truck with an impressive electric four-wheel drive system. Explore the specs and key features of this EV truck today.

The output of the dual-motor 4WD electric powertrain varies based on trim level. The Extended Range Motor has an output of 645 horsepower and 785 lb-ft of torque, as well as a 390-mile electric range. The Max Range model produces 760 horsepower and 785 lb-ft of torque. A 460-mile range is estimated for the upper trim. The Sierra EV can haul up to 10,500 lbs in the Max Towing mode. 

MultiPro Midgate

The Sierra EV comes with a MultiPro Midgate, a signature GMC feature that allows the truck bed to extend on demand. You may rely on this midgate feature for extra-long plywood or other long cargo. This feature works by first folding down the 60/40 split-folding bench seat in the cabin and removing the glass panel from the back of the passenger area. 


When these changes are made, the length of the truck bed increases to 9.1 feet. Drivers can extend the truck bed length even further to 10.10 feet by using the MultiPro Tailgate load stop. 

Advanced Braking Systems

This truck is equipped with advanced braking technology to mitigate an accident. The enhanced automatic emergency braking system keeps an eye on the vehicle ahead to determine the likelihood of an accident when you drive above 2 MPH. If a collision is detected, the system can increase braking power. 


The reverse automatic braking system is paired with rear cross-traffic braking. When the pickup is in reverse, back-facing cameras and sensors can detect collisions with other vehicles or obstacles. An alert will warn you about an impending collision, and the system will enhance emergency braking power to bring your truck to a hard stop. 

Google Built-In Infotainment

The Sierra EV has a 16.8-inch central touchscreen with Google Built-In technology, which optimizes in-cabin convenience with personalized driver profiles, connected apps, and voice-activated technology. Google Built-In gives drivers the advantage of Google Maps and data like Google’s points of interest to map fast routes, find charging stations, and more. A Bose seven-speaker audio system and a SiriusXM 360L trial are standard. 

Climate-Controlled Cabin

This pickup is prepared for all weather conditions with heated and ventilated front bucket seats, each with individual temperature controls. The seat ventilation settings can be linked to the climate system to automatically cool the cabin when the EV motor is remotely started. Heated rear outboard seats are also standard.

The Sierra EV has high-tech connectivity and safety systems, as well as an adaptable truck bed to haul long items. Ask about model availability at AutoNation Buick GMC West in Golden, CO.
