3WT/4WT Range Revealed by Natural Resources Canada now EPA Certified

Looks like the article has been taken down, good thing you captured the information.

If these numbers are accurate, that is a massive battery! If range is calculated from highway, 261 kWh, but most likely is calculated from combined, so 242 kWh. I think I saw 245 kwh somewhere else, so that would make sense.

To put the numbers another way, that is 1.72 mi/kWh on the highway.

450 miles range is likely calculated as "combined." Since it is 450 miles range ... on a per 100 miles basis that is 4.5 * 53.9 kWh = a battery pack usable capacity of 198 kWh. A Hummer EV has a 212 kWh usable pack... so this seems in line with expectations.

That's what I did, check your math. Looks like you did 4.5 x 43.9 not 53.9.

Does 1.724mi/kWh seem low for a ground up EV build? I was expecting much higher 2.2ish?

GM also does their EPA testing with about 1000 lbs of payload and they are still being conservative.

1.7 mi/kWh is more like Hummer EV highway efficiency. There are Hummer owners averaging over 2 mi/kWh mixed driving.

I see this quoted everywhere, but never any firm evidence this is the case. Also payload has very little effect on range, I would think 1000 lbs might lower it by 3-4% at most.

1.7 mi/kWh is pretty low, pretty much on par with the Lightning, especially for what seems like a much more efficient package compared to a Lightning.

I routinely get 2.5 mi/kWh in my R1T, and can get 2.7-2.9 mi/kWh at highway speeds using conserve (2WD) mode. That is driving as normal, and not trying to be more efficient (typically flow of traffic or 5-7 mph over), suspension set at normal ride height. It is a smaller truck though, so I would expect it to get higher efficiency.

Assuming the same 212 usable kWh pack as the Hummer, that’s over 2.1 miles/kWh

Also, both Hummer SUT and Lyriq owners are now seeing real-world ranges well over EPA ranges in mixed highway/city/secondary road trips. This bodes well for future Silverado owners’ range concerns. Too bad so many may decide to pass on this amazing e- truck because they are married to their phone apps.
