Chevrolet promised to deliver 400-miles of range with the all-electric Silverado EV Work Truck. As it turns out, they’ve done a lot better than that.

This morning Chevrolet announced that the Silverado EV Work Truck would travel up to 450 miles on a single charge. That’s up from the 400-miles initially promised and a massive 100 miles of range over the top trim GMC HUMMER EV.

That’s also a big jump over the Ford Lightning, which can travel 320-miles on a single charge using its extended-range battery pack and only 230 miles on the standard battery pack.

It’s also worth noting that at 450-miles, the Silverado EV now exceeds the range of most traditional ICE Silverado models.

This huge 450-mile range is courtesy of GM’s 24-module Ultium Battery pack, the same you’d find in the Edition 1 GMC HUMMER EV Pickup and the largest the company has announced they will produce. The Silverado EV’s battery capacity is expected to land at the same 212 kWh figure in the HUMMER EV.

Chevrolet also announced they would make a “smaller” range Silverado EV that travel “only” 350 miles.

The Chevrolet Silverado EV Work Truck goes on sale this spring for fleet customers, with the 350-mile range option coming “soon after”.

The full-featured Silverado EV RST First Edition will go into production later this fall for retail sales to traditional customers.
