According to GM, the Silverado EV is going have an estimated range of more than 400 miles on a full charge with their Ultium platform.

I'm going to assume that will be the max range since it's around the same as the Hummer EV pickup's max range of 350 miles.

400 miles is more than plenty for me with the driving that I do. Does anyone want/need more range from GM?

I read that GM is working on battery pack rated for over 200 kWh. If true, then over 400 miles is very possible but without going over 200 kWh I really doubt they'll get any exciting range numbers, EPA estimated or real-world.

Yeah they're already working on it for the Hummer I believe. Since the Silverado should be lighter than the Hummer it should better range with that battery.

Ford F150 Lightning seems to be getting 2.1 miles / watt and doesnt look to be quite as aerodynamic as Silverado EV. So, assuming Silverado EV gets ~2.0 miles / watt, with a 200kW battery pack, thats right at 400 miles, depending on load and conditions. I am pretty sure the EPA tests are done on a completely flat track so if you are in Colorado or PNW, you will not get that; if you are in Kansas or Texas, it might be pretty close.

No, even in winter (say 25% loss, 300 miles) it would work for me personally- adding one 30 min stop to a 600mi one-way is totally fine. There's a reasonable conversation to have with folks who want to tow trailers, boats, etc for long haul/touring trips. I've heard anecdotally that towing cuts range roughly in half (so 200 mi, best-case), which is about 3hrs @ 60mph, with a thin margin. 3 hrs is a fine interval to stop for a bathroom/snack/stretch break, provided it's quick, say 30 min or less. (15 or less would be ideal.) Longer stops could mean adding 2 charging hrs to a 10 hr trip (before traffic) making it into a 12 hr slog. So while more range would be nice, until energy densities really increase, I think the real-world DCFC charge rates/curve will be what people come to care about.

That's my use-case. Maine to Virginia and back, for Christmas, then again for a month from Feb-Mar. It's about a 13 hour drive on it's own, and depending on the EV range and charging speed, I'll add between 2 and 4 hours to the trip. I'm on this waiting list, because the 800v/350kW setup puts me at the low end of that extra time spent charging.

I've done the trip in an older Model S with 150kW max, I've done it in a Model 3 Performance with 250kW max, and a Performance Model X with 200kW max (one of their in-between battery pack revisions).

The 3 and the X were tolerable. The charging speed and curve on the S made it a pretty miserable time.

But now, we've got 2 dogs and a kid, so we're used to building in slightly longer stops anyway. 20 minutes is about the sweet spot per 3 hours of driving.

I cancelled my reservation after watching the F-150 Lightning videos regarding towing. A 73% loss of range while towing is not acceptable. So, the 300 mile pack turns into an 80 mile pack with simply connecting a trailer.

That means that the WT version of the Silverado EV which will likely come with a 250 mile range or so is going to be a 50-75 mile range pickup with a trailer in tow. Absolutely not practical.

GM says they're going to offer a version with "up to 20,000 lbs. towing" a year after launch. That'll be one hell of a circus trick! Can't wait to see the miserable range on that. 20k down the road for 10 miles.

You cancelled your reservation for the F150 or cancelled your reservation for the Silverado EV?

The F150 Lightning Extended Range has a 131 kWh battery pack... but if the Silverado EV has the claimed 200 kWh battery pack, your range may still be ok between stops.

Also, I thought Class IV towing with a normal ICE truck or SUV increases MPG fuel consumption by like 40%. Were EV truck buyers expecting 300 miles range while maxing out their GVW?

Honestly, after seeing that the stepped the blazer’s range so you had to pay more to get more I wouldn’t be surprised to see that with the Silverado. 😞 i guess with this new tax credit about to go through at least it’ll knock 7,500 off the price to upgrade it, if the dealerships don’t screw you out of it.

I sure as hell they weren't. Kinda self-explanatory, really, but some might have been caught up in the heat of the moment and now regret their decision. 🤷‍♂️ EV truck really isn't convenient for towing long distances. At least not yet. That's still for ICE to take care of.

Yes, for towing. I'm getting a Silverado because of this, with 400 miles you can eyeball it at say 200 miles towing depending on the details. That's enough to make it work. Kind of funny, we bought a Bolt just because it was the first decently priced EV with > 200 mi range, which is the minimum.

Anyhow I'm expecting 425-450 real world, as GM under promises and over delivers on range historically. But in reality you won't want to 100% charge or 0% discharge, so the extra 25-50 miles (if real) will basically be the 90%ish buffer you want.
