Granted, it’s most essential in the top-performing version of the future GMC Hummer, which will employ an all-wheel-drive system powered by one front motor feeding into a conventional differential, and two rear motors, each driving one rear wheel apiece.
As for the Hummer’s other powertrain options, we can look forward to a more basic AWD configuration with two motors total – one front, and one rear – as well as a RWD configuration with a single rear-mounted motor. And the air springs shown in GM’s published photos from the event? Most likely, those will be extra-cost optional equipment, for buyers who demand more smoothness and adjustability than steel coil springs can offer, but it’s possible they could come standard.
Unfortunately, there’s little chance we’ll learn the answer to that particular question when GM reveals the forthcoming Hummer EV on May 20th.
