For the first time ever, the GMC HUMMER EV has been caught undergoing testing. GM-Trucks.com has a huge 48-photo gallery of what we caught, what’s notable, what’s different and what it all means for the fully electric truck coming out this fall.
Our spy photographer relayed these details:
Up until now, just about every view available of the Hummer EV has been on its own, and in a controlled, public relations context. In our first shots of the electrified Hummer undergoing tests show the EV truck sharing image-space with a prototype for the 2022 Silverado’s mid-cycle facelift, a Chevy Tahoe, and a GMC Acadia. The Hummer EV on the flatbed is being pulled by a Chevrolet 4500-6500 HD, providing some measure of comparison between the new Hummer and the commercial-grade beast. There is also some traffic around the trailered Hummer, providing further points of comparison.
Some observations of the Hummer EV prototypes recently caught testing:
- A trim piece has been removed on the front bumper to show the mounting position of a front license plate.
- Hummer EV prototypes are equipped with redesigned tailgates, adding what appears to be a new back-up camera.
- Some initial photos of the Hummer EV were missing the shark-fin-style, roof-mounted antenna, but the initial prototypes are equipped with the antenna.
- Changes are visible on the prototypes’ rear control arms.
- Prototypes showcase new running boards, which have been changed to add steel tube protection for the rocker panels.
- Side mirrors are sleeker, and different from from what was revealed on the initially-revealed Hummer EV.
- Prototype interiors are covered in camouflage, but visible details appear to have screens consistent with official Hummer EV imagery.
