Top-performing versions of the GMC Hummer EV will use a powertrain similar to Tesla's Cybertruck.
GM's first confirmed pure-electric truck, the forthcoming GMC Hummer, is still mostly shrouded in mystery. We know that it will deliver up to 1,000 horsepower, with as much as 11,500 lb-ft of torque, but apart from that, most everything - including the design - is up in the air.
But thanks to some comments made during the automaker's recent fourth-quarter earnings webcast, things are starting to come into focus - slightly. During the cast, GM President Mark Reuss revealed that the forthcoming Hummer electric pickup will ship with up to three electric motors, powering both axles and allowing for the possibility of some sophisticated torque-vectoring.
Note that we said "up to" three motors. This is because the GMC Hummer will offer a number of different configurations, accounting for a range of consumer preferences relating to price and capability. For those that want it, Reuss says, the Hummer will offer a "basic package" without the same penchant for towing and off-roading as the top-spec models will have.
We imagine that GM will offer at least two different battery packs, as well - one short-range, and one long-range - and that the more "basic" trim levels won't be capable of the same 3-second 0-to-60 sprint as the top-performing version.
The news that GM's new battery-electric Hummer will pack up to three electric motors is notable, if for no other reason then because it's remarkably similar to the approach Tesla will take with the top-performing versions of the Tesla Cybertruck. With two motors powering one axle, each motor driving a single wheel, engineers will be able to very effectively vector torque at that axle for superior traction no matter the situation.
The forthcoming GMC Hummer battery-electric truck is scheduled for a proper unveiling on May 20th, long before its expected on-sale date in the fall of 2021. Until then, we guess we'll just have to get by.
