Here’s what the Hummer EV tells us about the Chevy Silverado EV

It’s a fairly secure bet that the fully electric Chevrolet Silverado that was confirmed on Tuesday—due by the middle of 2023, with a variety of additional than 400 miles—will appear like a Silverado. 

The Silverado is GM’s longtime bestselling pickup nameplate, and 1 of the leading-promoting trucks in a industry exactly where GM, Ford, and Stellantis hold the advantage. Mid- and complete-size pickups make up additional than 1 out of each and every six U.S. new-car sales.

Meanwhile, if you haven’t noticed, pickups evolve extremely, extremely gradually. And do not assume the Tesla Cybertruck will alter that course a lot. Automakers have stagnated in innovation paralysis since so a lot is at stake. An electric Silverado will need to have to appear like a Silverado, as gasoline versions continue to be constructed for a extended time, but also represent the future. 

It roughly compares to the level of stress that the group establishing the GMC Hummer EV currently faced. To pull off the revival of Hummer in an electric car, it necessary to develop a halo truck that nonetheless looked like a Hummer but showed its innovation in its on-road and off-road functionality.

Although the Hummer EV is an electric equivalent to physique-on-frame trucks, it does not have that layout. Neither will the Silverado EV that GM will develop in Hamtramck alongside the Hummer EV lineup. Earlier this week, GMC Hummer EV chief engineer Al Oppenheiser reasoned out why the extended-variety Chevy electric truck will just about undoubtedly share the Hummer EV platform rather than use the current Silverado physique-on-frame style. 

Working back from the targets—especially variety

It’s down to packaging. To get the 350 miles of variety anticipated for the Hummer EV SUT pickup—or additional than 400 miles for a leaner, significantly less off-road-focused Silverado EV, for instance—the cells necessary to attain that variety merely wouldn’t match.

GM “wouldn’t have been capable to stack as quite a few modules in between standard truck frame rails,” confirmed Oppenheiser, so they opted for a “structural sandwich” beginning with two rectangular plates of steel and two stout-searching side supports that could partly take the spot of frame rails. The battery pack also has its personal structure, with the front and rear cradle tied off from the front and rear of what’s efficiently a frame about the battery. 

“So it is type of a blend of physique-frame integrated, versus a regular physique-on-frame pickup,” stated Oppenheiser. “It enables us to hold our center of gravity low and the mass low, and we can package fundamentally any size module.”

With this layout, as GM pointed out final March at a presentation showcasing its Ultium Battery technology, it can mix or match modules in which cells are packed horizontally or vertically.

How large is that large battery?

Mathematically, primarily based on our notes and what GM has stated about its Ultium battery method, the modules add up to just below 9 kwh every. The 24-module battery—likely about 213 kwh gross—in the Hummer SUT is the biggest feasible for the architecture, although the 20-module pack (~178 kwh gross) is the biggest provided in the Hummer SUV, and a smaller sized 16-module pack (~142 kwh gross) is also on supply in the base 2X.

If GM offers the Silverado EV that biggest pack, it would need to have to achieve about two miles per kwh—a feasible target, potentially. For instance, GM could have the solution of creating the gearing of the electric motors taller than in the Hummers—roughly a ten.five:1 reduction ratio in back, and 13:1 in front to allow Ludicrous-mode-like Watts To Freedom launches—or of downsizing some of the propulsion systems from the Hummer EV SUV and SUT models’ 830-hp and 1,000-hp ratings, respectively.  

Other “like-segmented automobiles” to come

Although Oppenheiser didn’t mention or confirm the ‘BT1’ system name that is been reported in current months, and recommended as the prevalent glue in between electric trucks for GMC, Chevy, and Cadillac, he confirmed that the Hummer EV is “the initially of other like-segmented automobiles that can come off of it.”

“Our hope is that the Hummer is a halo car for the automobiles that will comply with us,” he stated, when we asked if a diverse project or platform will generate other electric trucks. “Our hope is that we use that halo philosophy to get them interested in…the future variants off of this electric truck architecture.”

Even prior to its launch, we’d venture to say the Hummer EV currently has generated a groundswell of interest. Will a Silverado do the same—and possibly an electric revival of the classic Blazer SUV

GM, and the group establishing these trucks, nonetheless has a lot to test and prove about the towing and hauling capacity, and longevity and endurance, in these trucks. Stay tuned as GMC will most likely be teasing additional of these traits in the Hummer EV this summer time.
