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

Share on:

It’s a very safe and sound bet that the thoroughly electric powered Chevrolet Silverado that was confirmed on Tuesday—due by the center of 2023, with a assortment of much more than 400 miles—will seem like a Silverado. 

The Silverado is GM’s longtime bestselling pickup nameplate, and one of the best-advertising vans in a market place exactly where GM, Ford, and Stellantis keep the edge. Mid- and complete-dimensions pickups make up additional than a single out of each individual six U.S. new-car or truck revenue.

Meanwhile, if you haven’t noticed, pickups evolve really, really slowly. And don’t imagine the Tesla Cybertruck will alter that course a lot. Automakers have stagnated in innovation paralysis simply because so significantly is at stake. An electric powered Silverado will require to glimpse like a Silverado, as gasoline versions continue to be created for a extensive time, but also stand for the future. 

It around compares to the level of tension that the crew acquiring the GMC Hummer EV presently faced. To pull off the revival of Hummer in an electrical motor vehicle, it desired to create a halo truck that nevertheless looked like a Hummer but showed its innovation in its on-street and off-highway efficiency.

Though the Hummer EV is an electric equivalent to physique-on-body vehicles, it does not have that structure. Neither will the Silverado EV that GM will establish in Hamtramck along with the Hummer EV lineup. Previously this week, GMC Hummer EV main engineer Al Oppenheiser reasoned out why the long-selection Chevy electrical truck will nearly surely share the Hummer EV platform relatively than use the present Silverado overall body-on-frame layout. 

Operating back from the targets—especially array

It’s down to packaging. To get the 350 miles of assortment expected for the Hummer EV SUT pickup—or more than 400 miles for a leaner, much less off-road-targeted Silverado EV, for instance—the cells needed to achieve that variety merely wouldn’t in shape.

GM “wouldn’t have been able to stack as many modules among typical truck frame rails,” verified Oppenheiser, so they opted for a “structural sandwich” starting up with two rectangular plates of metal and two stout-searching aspect supports that may well partly get the location of frame rails. The battery pack also has its have framework, with the entrance and rear cradle tied off from the front and rear of what is efficiently a body about the battery. 

“So it is type of a blend of overall body-frame integrated, compared to a traditional human body-on-body pickup,” said Oppenheiser. “It permits us to maintain our middle of gravity lower and the mass lower, and we can offer in essence any measurement module.”

With this structure, as GM pointed out previous March at a presentation showcasing its Ultium Battery technologies, it can blend or match modules in which cells are packed horizontally or vertically.

How big is that big battery?

Mathematically, based on our notes and what GM has stated about its Ultium battery approach, the modules include up to just less than 9 kwh each and every. The 24-module battery—likely all over 213 kwh gross—in the Hummer SUT is the biggest achievable for the architecture, even though the 20-module pack (~178 kwh gross) is the premier supplied in the Hummer SUV, and a smaller sized 16-module pack (~142 kwh gross) is also on present in the foundation 2X.

If GM presents the Silverado EV that greatest pack, it would will need to achieve about 2 miles for each kwh—a feasible concentrate on, perhaps. For instance, GM may have the possibility of creating the gearing of the electric powered motors taller than in the Hummers—roughly a 10.5:1 reduction ratio in back again, and 13:1 in entrance to empower Ludicrous-manner-like Watts To Liberty launches—or of downsizing some of the propulsion techniques from the Hummer EV SUV and SUT models’ 830-hp and 1,000-hp rankings, respectively.  

Other “like-segmented motor vehicles” to appear

Whilst Oppenheiser didn’t point out or validate the ‘BT1’ software title which is been described in latest months, and recommended as the popular glue among electric powered trucks for GMC, Chevy, and Cadillac, he confirmed that the Hummer EV is “the 1st of other like-segmented automobiles that can appear off of it.”

“Our hope is that the Hummer is a halo auto for the automobiles that will abide by us,” he explained, when we questioned if a diverse task or system will create other electric powered trucks. “Our hope is that we use that halo philosophy to get them fascinated in…the future variants off of this electric powered truck architecture.”

Even just before its start, we’d venture to say the Hummer EV now has generated a groundswell of interest. Will a Silverado do the same—and most likely an electrical revival of the common Blazer SUV? 

GM, and the crew building these vehicles, continue to has a lot to exam and show about the towing and hauling potential, and longevity and endurance, in these trucks. Continue to be tuned as GMC will most likely be teasing more of these attributes in the Hummer EV this summertime.
