Three all-new motors and five interchangeable drive units to create the “Ultium Drive” system.

• A 241 HP permanent magnet motor for front wheel drive applications.

• A 342 HP permanent magnet motor for front and rear wheel drive applications. The Hummer uses 3 of these to make 1,000+ HP.

• An 83 HP induction “assist” motor for AWD application.

is there a peak torque rating? (that's what's going to move these 2 1/2-4 ton lumps)
 
We'll have to wait on the Munro tear down to see if there is actually anything unique in these motors, or if there was copying of other innovaters.

GM hasn’t said, but the Hummer pickup will do 0-60MPH in 3.0 seconds and allegedly weighs 9,000 lbs. So the torque will be massive.

no good at math. but that's probably 1,200 ft/lbs & the booster motor they mention. so 300+ extra? 1,500 ft/lbs I guesstimate.
 
Will be interesting to see if an entrepreneur makes a refit pkg that bolts these into older cars or other vehicles.

Seeding a new era of consumer E-Rodding is a vector GM could use to assault the proprietary death grip Tesla maintains on its product. Going mainstream would gain market share, widen EV acceptance and leverage efficiencies of scale at the same time. Like VHS vs Beta-Max or PC clone vs Apple a more open platform could be a winner.

GM has already started.

The stator already looks unique. Like the Toyota stator looks unique. Weber will do an analysis sometime I hope. In ten years or so a lot will happen. From the nursing home window what will I care “there goes another them ev’s back in the day we had them that burned up right as we was driving.” “What’s for supper enchiladas again?”
 
The conversion business is going to be interesting. A motor and transmission coupled with a black box controller and sensors, mated with generic “ in the trunk “ battery pods could make this a viable business for some young mechanics out there. ;)
 
They are on the right track. But how well they will execute remains to be seen. If their system turns out to be an unreliable POS and works about as well as their V8-4-2 or their V8 converted to diesel or their auto transmission that was supposed to lock up into some kind of overdrive at a certain speed but just wandered around most of the time, that will continue to keep GM several years behind the industry leaders.
 
Pretty sure we've seen these before?

Electric "performance" is a tricky balance between motors, batteries, and charging.

These motors look great , but overall performance isn't determinable outside of the holistic package.

None of these mean much if the battery subsystem is unreliable, ages too quickly, or is unable to charge quickly on a trip.
 
From the last detail photo it appears the motor may be intended to run "wet" for cooling the stator with oil. The hairpin-type wiring is a modern automation-friendly feature that the Bolt and a few others already use, but notably not yet Tesla. The integral pinion on the stout motor shaft means only two bearings are required rather than the more common three (Tesla and others) or four (Leaf, Kona, Niro).

Designing new vehicles will be easier for GM's engineers with these items available in the company store.
 
I wish GM luck. So far, the incredible legacy car companies have fell short in comparison to Tesla, at least in EV technology.
All they really have is their name. I hope they live up to it.

I want to emphasize, probably ad nauseam at this juncture, lol, that in terms of actual CARS, the e-tron and Mach-E are fantastic. I've not driven the Taycan but I expect it is what one would expect from Porsche. No, they don't have Tesla's Auto Pilot, but they have nicer interiors (particularly the e-tron) and materials selection that one would expect from those brands.

GM's Bolt Gong Show has me a bit wary of their efforts, the others have managed to avoid this.

The Audi has a HUD, leather, a beautiful cluster, CarPlay...etc. Things you expect coming from a luxury ICE. The Tesla has none of the above, but it does have some amazing tech in its own right. The Tesla is also faster. The Audi is HEAVY.

I'd still choose an e-tron over a Model 3 at this juncture, having owned one and driven the other, it's just a nicer car/SUV. Tesla needs to add a HUD, I'd forgive them for their lack of CarPlay if they did that.
