The GM Ultium platform is rigid—rigid enough to allow Chevy to revive the notion of a unitized cab and box with an open bed that can expand into the truck’s interior by folding down a midgate, as popularized on the Chevy Suburban-based 2002-2013 Chevrolet Avalanche and Cadillac Escalade EXT.

The bespoke electric architecture allows the front seats to move closer to the front axle and farther away from the rear seats, while still leaving room for a 5-foot-11-inch box. That bests the combustion Silverado’s by an inch and the Ford F-150 Lightning’s by 4 inches. Fold the midgate down, and you get 9 feet of floor space to the closed tailgate—10 inches more than on a regular-cab, long-box pickup.

Open the optional Multi-Flex tailgate and pop up its load limiter, and the floor measures 10-foot-10. As on the original Avalanche, the midgate can fold down, with the rear window and optional tonneau cover sealing the cabin from the elements. Or doff the tonneau, pop the rear glass out, stow it on the lowered midgate, and fully open the cab to the bed.

One major difference between the Silverado EV and the Avalanche: The midgate and seat are split 60/40, and everything folds forward into the cab either 60 or 100 percent. The original Avalanche midgate folded backward to stow in the bed floor.

The 2024 Chevrolet Silverado electric truck is roughly the same size outside as its crew-cab/short-box combustion-powered counterpart, but it’s considerably larger inside. Substantial differences in width and length between the Silverado electric and the GMC Hummer EV serve to illustrate the GM Ultium platform’s range of adjustability.

The Silverado EV’s 145.7-inch wheelbase is 10.1 inches longer than the Hummer pickup’s and 1.7 inches shorter than a comparable crew-cab, short-box Silverado—while sharing the costly-to-develop crash safety structures. Varying the width of the suspension crossmembers and length of the control arms alters the track width affordably.

The F-150 Lightning’s frunk is way bigger—like V-8 big. Chevy shrunk the Silverado EV’s nose and then moved the HVAC componentry out of the dash and into the nose to free up cabin stowage space. Chevy’s smaller “eTrunk” does feature tie-down hooks and a 120-volt power outlet, however, and on RST models the lid will open and close electrically. The storage capacity should match the Hummer EV’s 9.0 cubic feet, well down from the 14.1 cubes available in the Ford electric truck’s frunk.

The top-trim models of the 2024 Chevrolet Silverado EV will share the Hummer EV pickup’s 24-module 200-kWh battery pack. Estimated range is 400 miles for both the RST and the work truck. Chevy will offer smaller battery packs, with the Hummer SUV’s 20-module 167-kWh pack seeming like one obvious option. Two permanent-magnet-type motors will power all first-year Silverado EVs via single-speed reduction gearboxes.

They’re similar to the Hummer motors, and neither can be declutched during low-demand cruising. In First Edition RST models set to Chevy’s Wide-Open Watts (WOW) mode, they’ll be tuned to produce “up to 664 hp and 780 lb-ft of torque.”

Relative to the Hummer’s Watts to Freedom (WTF) mode, WOW does without the sound-effects fanfare, and it propels the 2024 Chevrolet Silverado EV to 60 mph in a claimed 4.5 seconds. The more basic AWD commercial-fleet work trucks will produce “up to 510 hp and 615 ft-lb of torque.” (Fleet managers are rightfully reluctant to arm employees with 600-plus-horsepower trucks.) Lower-powered and single-motor two-wheel-drive model variants are expected in the coming years.

The GM Ultium platform’s 800-volt system can accept 350-kW DC fast charging. We’re told this will add 100 miles of range in 10 minutes. RST owners will have access to Ultium Charge 360, GM’s holistic EV charging plan, which is designed to simplify the overall charging experience, providing access to more than 100,000 publicly available charging points across the U.S. and Canada. WT customers get access to a similar fleet service plan.

It will be possible to plug devices into 10 AC plugs found in the 2024 Chevrolet Silverado EV electric pickup. There are four 120-volt outlets in the pickup box plus one each in the frunk and center console. There’s a single 240-volt outlet in the pickup box, and an accessory “Power Bar” that plugs into the CCS charge port will provide two additional 120-volt outlets and one 240-volt socket. The Power Bar also enables buddy-charging of another EV, with the charging rate approaching that of a Level 2 home charger.

In total, the system can export 10.2 kW of electric power, and the driver can specify a minimum remaining state of charge or driving range to stop exporting power to ensure safe return to a charging station. Probably not coincidentally, that just eclipses the 9.6-kW power-export limit of Ford’s F-150 Lightning. All of this means it should be just as easy to power your house during an electricity outage with an electric Silverado EV as it is with an F-150 Lightning.
