What's the point of putting 30,000 mile hub motors on a million mile battery?
Even the lowly Nissan leaf gear box will go at least 160,000 miles if you never check or change the oil.

I like the motor per wheel approach and the availability of the space between the wheels for lowering the bed or batteries or whatever.
But the same could be achieved with a swingarm suspension with hypoid gears and the motor in between the main bearings of each swingarm. The motors could rev higher, the hypoid gear set would add less unsprung weight than a rim motor would, and the motors would be less vulnerable.
It would be no good for the front suspension as you cannot steer, obviously, but neither is a rim motor any good there as the the motor and steering pivots get in each others way and the total weight gets out of hand.

This truck is never getting produced.
Workhorse spun off Lordstown Motors to put their unprofitable truck project and associated R&D money sinkhole somewhere it won't bother their core focus on more profitable last-mile delivery vans. For more evidence, here's the drivetrain on Workhorse's C1000/650 vans:

NOT the unworkable hub motor BS.

The machining on that looks expensive

Back in the days of black and white photography they did it like that.

I'm not a hub motor expert but I'm pretty sure that's not a hub motor.

He's saying this is the Workhorse axle motor. Workhorse dropped the hub motor design and another investor bought it and created Lordstown motors named after the Lordstown GM plant he also bought to make his pickup.
To me the Lordstown guy seems serious about making the EV, and it seems all the prototypes have hub motors. Maybe they have figured out the shortcomings or know nobody else is making pickups that last much more than 200,000 either without a $5000 motor or a $3000 transmission or $4000 worth of fuel injector work or all of the above. Even if it needed $10,000 worth of new hub motors after that it's still under what and average new pickup is going to bleed you.

200k pickups are fairly common, mostly the ford /chevy big block diesel. most achievements not requiring motor tranny or FI rebuilds. Brakes, tires, suspension otoh, yup common.

Well my supposedly "bulletproof" 5.9 Cummins needed injectors in under 200,000 miles and the parts alone were over $4000 (new Bosch injectors, new harness, and new gaskets) installed would have been $5000 even. So great, the Cummins goes 500,000 miles but I could have dropped a whole new Hemi in there at that point for less than just the Cummins injectors. My 3.0 TDI just got all new injectors at 80,000 miles and they are similar $400 each just for the part. Luckily that was done 100% under the extended dieselgate warranty. It's always something, expecting zero high dollar maintenance after 200,000 miles is unlikely.

Considering a brushless motor will have fewer wear and tear, I wouldn't expect it to be made to a much lower standard.
