The 2024 GMC Sierra EV Denali Edition 1, which is the highest-possible spec for GMC’s latest battery-powered truck, got a slight bump in the range and towing capacity departments ahead of this summer’s start of deliveries.
Now, GMC estimates that the top-trim Sierra EV can travel up to 440 miles on a full charge–40 miles more than initially estimated–and can tow up to 10,000 pounds–500 more than before. The maximum payload has also been increased by 150 pounds for a total of 1,450 pounds on the Sierra EV Denali Edition 1.
