Part 4/7:
The heart of the review comes when the Sierra EV is hitched to a 24-foot trailer weighing around 8,000 pounds. This hands-on experience highlights GMC's intelligent towing technologies, including a trailer app visible on the infotainment screen that offers real-time analytics and adjustments.
GMC's proprietary "Super Cruise" feature permits hands-free driving while towing, an industry first. The technology continuously monitors the truck's position, even adapting to the presence of a trailer, creating an effortless driving experience.
