The GMC Hummer EV won't officially launch until fall 2021, but it's already throwing down some impressive numbers -- most notably, 1,000 horsepower and a whopping 11,500 pound-feet of torque. Thing is, that second number isn't necessarily an accurate representation.

It all comes down to what specification you use. GMC's massive number appears to correspond to wheel torque, which is traditional motor torque multiplied through the transmission's drive ratio. Jason Fenske from Engineering Explained has a great video that spells out the difference, a piece he published following Tesla's claim that the Roadster 2.0 will produce more than 7,000 lb-ft of torque. Fenske used a Dodge Challenger SRT Demon as an example. That model produces 972 Newton-meters of engine torque (770 lb-ft). However, multiplied through its gear ratios, you get 14,000 Nm of wheel torque (10,325 lb-ft) in first gear.
