Lightning ER vs Hummer 2X, HorsePower and Torque stats

[Lightning Rod]

A coworker if mine just bought a Hummer 2X. Looks really nice but I didn't have a chance to speak with him yet, so I did some research. My 2023 Lariat ER has 580 HP compared to his 570 HP, yet, take a look at these torque specs. Is this a typo? Google AI came up with this passage about the torque difference...

"When comparing torque between a 2023 Ford F-150 Lightning with the extended range battery and a GMC Hummer EV 2X, the Hummer has significantly more torque, with the Lightning producing 775 lb-ft of torque while the Hummer 2X delivers 7,400 lb-ft of torque; making the Hummer significantly more powerful in terms of torque despite having less horsepower overall."

7,400 lb-ft of torque? That just doesn't sound right. This is the lower HP hummer. The 3 motor version produces 830 HP!! Can this be a real torque spec?

The lightning has over 7500 ft lbs of torque.

These numbers are achieved by taking the motor torque and multiplying by the gear ratio of the drive.

Misleading, yes, big numbers gooder.

Sounds like Ai is off by a factor or 10 for the Hummer Tq.

That's what I thought, but going to Hummer site, they tout the same torque spec figures. It just doesn't make sense.... that's why I started this thread, to see what you guys think about these claims.

These "at the drive wheels" torque claims began with the Tesla Cybertruck, I believe. Then Hummer did the same slight of hand (or fraud, depending upon your perspective) afterwards.

The torque quoted for an automotive prime mover has been at the flywheel for about a century. Tesla wanted a more impressive figure than the other trucks, (despite having less torque at the motor shafts than the Ford and Chevy). So they quoted drive wheel torque, without making it clear that that is what they were doing. Sleezy. Some of the auto mags just naively repeated the figures, making it seem, to some gullible readers, that the Tesla actually had stunningly high torque. Most diesel 4WD pickups have more drive wheel torque than the Tesla, (or the Hummer) by a pretty wide margin. Even a fairly small John Deere tractor has more drive wheel torque than the Tesla, because of the huge total gear reduction.

Some sycophantic automotive journalists wrote wobbly words about the Tesla claim without calling it out for the fraud that it was (is).

Granted, having a single speed and a large total reduction (about 9.7:1 for the Ford and 15: 1 for the Cybertruck) means that the torque curve at the drive wheels is different than it is for a typical ICE with a ten-speed gearbox. However, the natural great low speed torque and diminishing high speed torque of an electric motor ends up being similar to the diminishing drive wheel torque that occurs as a ICE truck shifts up through the gears (going, in very rough terms from about 16:1 in first to 3.5:1 in the highest gear). As it turns out, just knowing the HP figure and weight is sufficient for predicting performance, and a 500 HP ICE truck performs about as well as a 500 HP electric truck: they are both crazy fast.

Most customers and many hot-rodders don't understand the way in which torque and rpm interact to produce horsepower... so we still have arguments about what you "Need" for a good 1/4 mile time. "Ya need torque for acceleration, and HP for top speed." That's BS. Torque does not imply any acceleration at all: How fast does a bolt that has been torqued to 100 lb ft accelerate when you apply 90 lb ft via a torque wrench?
