For enhanced safety, the front and second-row seat shoulder belts of the Mercedes EQS SUV have pretensioners to tighten the seatbelts and eliminate dangerous slack in the event of a collision and force limiters to limit the pressure the belts will exert on the passengers. The GMC Hummer EV SUV doesn’t offer pretensioners for its rear seat belts.

The EQS SUV’s pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The Hummer EV SUV doesn’t offer pre-crash pretensioners.

The Mercedes EQS SUV has a standard driver’s side knee airbag mounted low on the dashboard. The knee airbag helps prevent the driver from sliding under the seatbelts or the main frontal airbag; this keeps the driver better positioned during a collision for maximum protection. A knee airbag also helps keep the legs from striking the dashboard, preventing knee and leg injuries in the case of a serious frontal collision. The Hummer EV SUV doesn’t offer knee airbags.

The EQS SUV has a standard front seat center airbag, which deploys between the driver and front passenger, protecting them from injuries caused by striking each other in serious side impacts. The Hummer EV SUV doesn’t offer front seat center airbags.

The EQS SUV has a standard Post Collision Brake, which automatically applies the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The Hummer EV SUV doesn’t offer a post collision braking system: in the event of a collision that triggers the airbags, more collisions are possible without the protection of airbags that may have already deployed.

Earlier warning of stopped traffic, traffic signals, dangerous road conditions, weather, or accidents, can keep driver's safer and prevent crashes. The EQS SUV has Car-to-X Communication, a system that seamlessly communicates important warnings to the driver about impending danger, if they're available. The Hummer EV SUV doesn’t offer a system that can receive automated systems from infrastructure or other vehicles.

Both the EQS SUV and Hummer EV SUV have rear cross-traffic warning, but the EQS SUV has Active Brake Assist (automatically applies the brakes) to better prevent a collision when backing near traffic. The Hummer EV SUV’s Rear Cross Traffic Alert doesn’t automatically brake.

Both the EQS SUV and the Hummer EV SUV have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, height adjustable front shoulder belts, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, lane departure warning systems, blind spot warning systems, around view monitors, rear cross-path warning and driver alert monitors.

Warranty

The EQS SUV comes with a full 4-year/50,000-mile basic warranty, which covers the entire truck and includes 24-hour roadside assistance. The Hummer EV SUV’s 3-year/36,000-mile basic warranty expires 1 year or 14,000 miles sooner.

The EQS SUV’s corrosion warranty is unlimited miles longer than the Hummer EV SUV’s (unlimited vs. 100,000 miles).

The EQS SUV has a standard locking charge port which locks and unlocks with the power locks. The Hummer EV SUV doesn’t have a locking charge port. A locking charge port prevents tampering and damage.

Brakes and Stopping

For better stopping power the EQS SUV’s brake rotors are larger than those on the Hummer EV SUV:

	EQS SUV 450	EQS SUV 580 4MATIC	Hummer EV SUV
Front Rotors	15.3 inches	16.3 inches	14 inches
Rear Rotors	14.9 inches	14.9 inches	14 inches

The EQS SUV stops much shorter than the Hummer EV SUV:

	EQS SUV	Hummer EV SUV
60 to 0 MPH	108 feet	142 feet	Motor Trend

Tires and Wheels

The EQS SUV’s tires provide better handling because they have a lower 45 series profile (height to width ratio) that provides a stiffer sidewall than the Hummer EV SUV’s 70 series tires. The EQS SUV’s tires are lower profile than the Hummer EV SUV’s 55 series tires.

For better ride, handling and brake cooling the EQS SUV has standard 21-inch wheels. Smaller 18-inch wheels are standard on the Hummer EV SUV.

Changing a flat tire near traffic can be dangerous and inconvenient. The run-flat tires available on the EQS SUV can be driven up to 50 miles without any air pressure, allowing you to drive to a service station for a repair. The Hummer EV SUV doesn’t offer run-flat tires.

Suspension and Handling

The EQS SUV’s drift compensation steering can automatically compensate for road conditions which would cause the vehicle to drift from side to side, helping the driver to keep the vehicle straight more easily. The Hummer EV SUV doesn’t offer drift compensation steering.

The EQS SUV 450+ handles at .86 G’s, while the Hummer EV SUV 3X pulls only .70 G’s of cornering force in a Motor Trend skidpad test.

The EQS SUV 450+ executes Motor Trend’s “Figure Eight” maneuver 2.2 seconds quicker than the Hummer EV SUV 3X (26 seconds @ .7 average G’s vs. 28.2 seconds @ .64 average G’s).

Chassis

The Mercedes EQS SUV may be more efficient, handle and accelerate better because it weighs about 2250 to 2850 pounds less than the GMC Hummer EV SUV.

The EQS SUV is 4.9 inches shorter than the Hummer EV SUV, making the EQS SUV easier to handle, maneuver and park in tight spaces.

The EQS SUV is 6.4 inches narrower than the Hummer EV SUV, making the EQS SUV easier to handle and maneuver in traffic.

The EQS SUV is 10 inches shorter in height than the Hummer EV SUV, making the EQS SUV much easier to wash and garage and drive (lower center of gravity).

Passenger Space

The EQS SUV offers optional seating for 7 passengers; the Hummer EV SUV can only carry 5.

Cargo Capacity

The EQS SUV’s liftgate lifts up in one piece, completely out of the way of loading and unloading, while sheltering the cargo loading area. The Hummer EV SUV’s swing out door blocks loading from the passenger’s side.

To make loading groceries and cargo easier when your hands are full, the EQS SUV’s liftgate can be opened and closed just by kicking your foot under the back bumper, leaving your hands completely free. The Hummer EV SUV doesn’t offer a hands-free gesture to open its cargo door, forcing you to put cargo down if your hands are full.

Servicing Ease

An ASSYST PLUS is standard on the EQS SUV to save the owner time and money by calculating maintenance intervals based on odometer mileage. This takes the guesswork out of keeping your vehicle in top condition and helps it last longer. GMC doesn’t offer a maintenance reminder on the Hummer EV SUV.

Ergonomics

Unlike the driver-only memory system in the Hummer EV SUV, the EQS SUV has standard driver and passenger memory, so that when drivers switch, the memory setting adjusts the driver’s seat, steering wheel position, outside mirror angle and climate settings and the front passenger seat also adjusts to the new passenger’s preset preferences.

The EQS SUV offers an optional heads-up display that projects speed and navigation instruction readouts in front of the driver’s line of sight, allowing drivers to view information without diverting their eyes from the road. The Hummer EV SUV doesn’t offer a heads-up display.

The EQS SUV’s front and rear power windows all open or close with one touch of the switches, making it more convenient at drive-up windows and toll booths, or when talking with someone outside of the car. The Hummer EV SUV’s power windows’ switches have to be held the entire time to close them fully.

If the windows are left open on the EQS SUV the driver can close them all at the outside door handle or from a distance using the remote. On a hot day the driver can also lower the windows the same way. The driver of the Hummer EV SUV can only close the windows from inside the vehicle, with the ignition on.

Heated windshield washer fluid is optional on the EQS SUV to defrost the washer nozzles and quickly clear ice and frost from the windshield without scraping. The Hummer EV SUV doesn’t offer heated windshield washer fluid.

To improve rear visibility by keeping the rear window clear, the EQS SUV has a standard rear wiper. The Hummer EV SUV doesn’t offer a rear wiper.

To help drivers avoid possible obstacles, the EQS SUV has standard cornering lights to illuminate around corners when the turn signals are activated. The Hummer EV SUV doesn’t offer cornering lights. The EQS SUV also has standard adaptive headlights to illuminate around corners automatically by reading vehicle speed and steering wheel angle.

To better shield the driver and front passenger’s vision, the EQS SUV Maybach has standard dual-element sun visors that can block glare from two directions simultaneously. The Hummer EV SUV doesn’t offer secondary sun visors.

Manual rear side window sunshades are available in the EQS SUV to help block heat and glare for the rear passengers. The Hummer EV SUV doesn’t offer rear side window sunshades.

The EQS SUV has standard front air conditioned seats and the EQS SUV Maybach also has them in the second row. This keeps the passengers comfortable and takes the sting out of hot seats in summer. The Hummer EV SUV doesn’t offer air-conditioned seats in the rear.

The EQS SUV offers optional massaging front and rear seats (rear massaging seats standard on Maybach). Massaging seats aren’t available in the Hummer EV SUV.

The EQS SUV’s Active Parking Assist can parallel park or back into a parking spot by itself, starting, stopping and changing direction automatically. Remote Parking Assist will park and retrieve your car remotely: press a button and watch it park itself. This is ideal for tight locations. The Hummer EV SUV’s automatic parking system does not offer parking by remote control.

Model Availability

The EQS SUV is available in both rear-wheel drive and four-wheel drive configurations. The Hummer EV SUV doesn’t offer a two-wheel drive configuration.
