The All-Electric GM Hummer: A Revolutionary Off-Road Experience

General Motors has yet to reveal in-depth details about the all-new, all-electric Hummer until May 20. Nonetheless, a recent photo presented at an electric vehicle showcase reveals that this innovative vehicle will feature four-wheel independent suspension with air springs.

Exceptional Suspension Design

The Hummer, available in both pickup and SUV body styles, will utilize a cutting-edge control-arm suspension design at all four corners. More importantly, while some variants will come standard with robust steel springs, higher trim levels are expected to incorporate advanced air springs.

Powerful Motor Configurations

This particular electric chassis represents a top-tier trim level, equipped with three motors, which can be identified by their three sets of distinct orange cables—one located at the front and two at the rear. The Hummer’s offerings will include:

• A single rear motor for standard operation.
• One front and one rear motor to facilitate all-wheel drive.
• One front and two rear motors for high-performance all-wheel drive.

The three-motor configuration promises an impressive output of up to 1000 horsepower, powered by a substantial battery system securely placed underneath the vehicle, likely fortified by heavy, armor-like plating for off-road protection.

Advanced Off-Road Capabilities

In contrast to competitors like Rivian, the Hummer is reported to lack a four-motor configuration that enables independent control of wheels, a highly desirable feature for precision during diverse driving conditions. Moreover, whether the Hummer will incorporate mechanically locking front differentials or rely on brake-based torque vectoring for optimal off-road traction remains unclear.

When it comes to traction, the Hummer appears to utilize BF Goodrich Mud Terrain T/A KM3 tires, which are available in sizes ranging from 28 to 39 inches. While it remains unconfirmed, it’s unknown whether these tires will be a factory option or solely part of this prototype.

Reflecting on Legacy

Unlike the previous Hummer H2, which was founded on a conventional ladder frame from the Chevy Tahoe and incorporated a live rear axle, this electrified model is returning to its roots. The original AM General HMMWV featured a four-wheel independent suspension with portal axles for enhanced ground clearance. The transition to a modern EV skateboard platform allows for an efficient design, positioning the electric motors inline with the axles, thereby optimizing space and energy transfer to the wheels.
