Real world highway range 70 mph

InsideEV just did a range test on the Hummer EV at 70 mph and nearly got 350 miles! At 1.6 miles per kWh. This is above the combined EPA range rating of 329. This is a really impressive result, I think it’s very likely the large pack in the Silverado will go over 400 miles. I’m also hopeful the base pack will get over 300.

It will come down to the battery pack size. Hummer EV has 212kw, which is huge but then again the Hummer is huge.

I doubt the std. battery in the WT will get > 300 miles.

If battery technology improves and higher kw can be achieved in the same footprint then maybe but no indication of that so far.

I think EV manufacturers are counting more on EV charger proliferation over the next 2-5 yrs than on a major battery technology breakthrough.

The hummer and Silverado will share a pack, for the higher range model. The lower range model will have the same room with fewer modules installed, there’s no size or room limits.

Good to know.

It’s wait and see.

400+ would be nice, but since that will probably not be an easy or cheap option for WT, I’m okay with 300 miles too. It’s not too much less than what I get from my current Silverado.

At a recent EV engineering conference, GM‘s lead battery engineer Andy Oury showed 3 Ultium EV truck pack sizes - 16 24-cell modules, 20 modules, and 24 modules. All 24-cell modules will have the same kWh rating, so just do the math to estimate the usable kWh and proportion the approximate range for each size. Note that trucks w/ smaller packs will be lighter, so may get slightly better miles/kWh efficiency.
