EV trucks sound good but you can't haul anything heavy or your range plumments. Unless the battery is huge but that is weight. A truck that can't haul is just for show.

Even gasoline trucks are stupid no low end torque, you need to rev it. I had a 6 cylinder Cummins diesel and at 500rpm idle on a hill it could move the 10,000 pound truck up the hill.

I feel like this is less true nowadays. Or at least, less of a concern.

I have a Rivian and my 400mi range gets cut significantly (down to 200 or 300, depending on the trip) when I have 7k lbs on the back, but never enough to stop me from towing. And with good charging in the area, it's a non issue. And waaaaayyyyy cheaper than diesel.

Maybe if I was towing daily, I'd feel different. Your mileage may vary. (Couldn't resist the closer!)

Edit: btw instant torque is a game changer. You can't beat an EV on that front

I used to think this way, but it turns out that EV trucks hold up on range better than one would expect thanks to regenerative breaking. The added weight of cargo requires more energy to get up to speed, but you get most of that back when breaking, so it's not lost energy. Meanwhile, a gas or diesel truck's range plummets when hauling since all the energy used to accelerate the load is lost in breaking. I'm not saying that EV hauling is perfect or a solved problem, but that the trades offs aren't as intuitive as they might seem.

You should watch this video - aero dominates vs weight (factors very little), especially with strong regen

I borrow my brother’s truck all the time to transport various DIY supplies. I could probably get a roof rack for my car for things like plywood and drywall, but borrowing the truck is easier.

First, the intended customers of the Cybertruck don’t need to haul anything; it’s a lifestyle vehicle. Second, EVs have solved the torque problem.

Are you from 2010?

My EV has 470PS, it can hauul plenty heavy for long range. Weights 2.2 tons.

Even the Ford F-150 Lightning was already able to pull 4.5t and has a range of 300 miles.

A huge fraction of the truck owners barely (if ever) haul anything, so that's not a dealbreaker for an EV truck.

It just has to look manly and rugged, any actual offroad or hauling capabilities are at best a nice-to-have.

Some gas engines have low end torque, big block V8s and anything turbo. But yeah if hauling uphill is your thing diesel is a no brainer. It would be great if our half ton and midsize trucks had diesel options but as usual other countries have better options.

Personally I'm going hybrid truck next time. The advantages of electric (torque, 240V inverter) with the flexibility of gas. Payload is lower but I'm hoping they fix that by the time I need a new truck
