Electric Suburban / Electric Tahoe / Yukon / Escalade EV

Lol u pretty much proved my point on the lightning with towing. And all your battery range in cold weather is ev cars. This forum is about big suv EV’s weighing probably 6000 lbs+? With 4-6 people and possibly luggage weighing it down as well. I’m just saying the first 5-10 years of GM and Ford doing EV’s is not going to go well. Majority of people on this forum will look at big suvs and trucks, and the f-150 lightning is not doing well so far when u wana use it for truck stuff. If u just drive back and forth to work and never tow and charge at home then sure it’s ok. But long distance travel and or tow, bad news.

Find me an EV charging station that can accommodate an EV pickup truck with a 16+ foot trailer hooked up lol.

This is a shortsight for sure because most dont have pass thrus. Partly due to space. But something that needs to be thought of for sure. Good point.

Bob Lutz (my favorite auto industry executive) has a great perspective on this debate. EV's aren't the solution for most of us. Plug-in hybrids are. 30-50 miles of range on battery power will cover 90% of the trips that most folks have running around town and commuting. But the gasoline engine is there when needed to extend the range or help handle towing duty in a truck. The problem? Complexity. Cost. Maintainability.

I am a fan of plug ins. And just hybrids in general. Toyota hybrids are stupid reliable. Seems like they found a way to keep it reliable even when it is complex. A diesel hybrid would be so sweet

Agreed. And, adding 30-50 miles of range can be done with a standard 20A household circuit overnight, simplifying the infrastructure requirements.

I've said it before and I'll say it again.
I don't see full electric getting my attention until a next gen battery is utilized. Range, especially with respect to towing, is the main detractor for me. I'd be all over a plug in hybrid with ~50 miles of on board electric range and the 3.0L diesel coupled to a generator to keep batteries topped up and motors humming when range is exceeded or towing. Tune the engine to run at a fixed RPM that has been optimized for efficiency.

Locomotive EMDs have been doing this for decades.

Hydrogen is even more embryonic than full electric so, despite what is hyped, it isn't a viable option for decades. There is no cost effective way to generate hydrogen, compress it, etc. Doesn't make sense to even discuss it. Manufacturers are wasting their time even developing engines for it. (I have 15 years in generating power from renewables. 90% of our business is ICE engines fueled by biogas, landfill gas, etc. So I pay a lot of attention to new renewable fuel tech.)

For me, I need to be able to go at least 400 miles on a single charge while towing because there are no EV charging stations that can accommodate a EV truck with a trailer at the moment. Also, they need to account for battery age based degradation. I think we're looking at 900-1200 miles of range unloaded.

If memory serves, American diesel generators run at 60 Hz and so the generators turn 1800 rpms or 3600 rpms and the Euro standard is 50 hertz and those generators turn 1500 and 3000 rpms. I think a 60hz genset can also turn at 2400 rpms but it's been a long time since I thought about such things.

Mostly correct, but what is cool about EV is that they don't use AC, so RPM/frequency doesn't matter. The battery and motor side is all DC. Therefore, the manufacturers could design the engine around an optimum RPM and then design the inverter to handle whatever that is. Inverters can handle any range of incoming voltage and frequency that they are designed for.

You tow up a steep mountain loaded in a gas or diesel? Hate to break it to you but range becomes abysmal.

It's evident some don't here so they think the ev with less range in those conditions is some outliers.

It's typical for a gasser to get 6mpg when loaded towing. Sometimes less.

That's why I said it's misinformation because it is.

Say what? I thought mileage went up when towing a heavy load up a step grade! How could I be so wrong, and who mislead me along the way?
