Compare the2025 Cadillac LyriqVS 2025 GMC Hummer EV SUV

For enhanced safety, the front and rear seat shoulder belts of the Cadillac Lyriq 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 Cadillac Lyriq has standard driver and front passenger side knee airbags mounted low on the dashboard. These airbags help prevent the driver and front passenger from sliding under their seatbelts or the main frontal airbags; this keeps them better positioned during a collision for maximum protection. Knee airbags also help 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.

In a Vehicle-to-Vehicle Frontal Crash Prevention 2.0 test conducted by the Insurance Institute for Highway Safety (IIHS), the Cadillac Lyriq achieved a “Good” rating - the highest possible - for its performance in forward collision warning and automatic braking systems, demonstrating its excellent capabilities in preventing collisions. The GMC Hummer EV SUV has not been tested.

Both the Lyriq and Hummer EV SUV have Rear Cross Traffic Alert, but the Lyriq has Rear Cross Traffic Braking (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 Lyriq 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 available driver alert monitors.

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

Cadillac’s powertrain warranty covers the Lyriq 1 year and 10,000 miles longer than GMC covers the Hummer EV SUV. Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 6 years or 70,000 miles. Coverage on the Hummer EV SUV ends after only 5 years or 60,000 miles.

The Lyriq’s 6 year corrosion warranty has no mileage limitations, but the corrosion warranty on the Hummer EV SUV runs out after 100,000 miles.

J.D. Power and Associates’ 2024 survey of the owners of three-year-old vehicles provides the long-term dependability statistics that show that Cadillac vehicles are more reliable than GMC With 10 fewer problems per 100 vehicles in the first three years of ownership, J.D. Power ranks Cadillac higher than GMC.

On the EPA test cycle the Lyriq gets better mileage than the Hummer EV SUV:

The Lyriq can travel longer on a full charge than the Hummer EV SUV on a full charge:

The Lyriq stops much shorter than the Hummer EV SUV:

The Lyriq’s standard tires provide better handling because they have a lower 50 series profile (height to width ratio) that provides a stiffer sidewall than the Hummer EV SUV’s 70 series tires. The Lyriq’s optional tires have a lower 40 series profile than the Hummer EV SUV’s 55 series tires.

For better ride, handling and brake cooling the Lyriq has standard 20-inch wheels. Smaller 18-inch wheels are standard on the Hummer EV SUV.

Having a flat tire is dangerous, inconvenient and expensive. The self-sealing tires standard on the Lyriq can automatically seal most punctures up to 3/16 of an inch, effectively preventing most flat tires. The Hummer EV SUV doesn’t offer self-sealing tires.

The Lyriq’s front to rear weight distribution is more even (50% to 50%) than the Hummer EV SUV’s (48% to 52%). This gives the Lyriq more stable handling and braking.

The Lyriq AWD handles at .82 G’s, while the Hummer EV SUV pulls only .76 G’s of cornering force in a Car and Driver skidpad test.

The Lyriq Luxury AWD executes Motor Trend’s “Figure Eight” maneuver 1.8 seconds quicker than the Hummer EV SUV 3X (26.4 seconds @ .71 average G’s vs. 28.2 seconds @ .64 average G’s).

The Cadillac Lyriq may be more efficient, handle and accelerate better because it weighs about 3050 pounds less than the GMC Hummer EV SUV.

The Lyriq is 10 inches shorter than the Hummer EV SUV, making the Lyriq easier to handle, maneuver and park in tight spaces.

The Lyriq is 8.7 inches narrower than the Hummer EV SUV, making the Lyriq easier to handle and maneuver in traffic.

The Lyriq is 13.5 inches shorter in height than the Hummer EV SUV, making the Lyriq much easier to wash and garage and drive (lower center of gravity).

The Lyriq offers available computer-generated active noise cancellation to help remove annoying noise and vibration from the passenger compartment, especially at low frequencies. The Hummer EV SUV doesn’t offer active noise cancellation.

The Lyriq’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 Lyriq’s available 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.

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

The Lyriq’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.

To help drivers avoid possible obstacles, the Lyriq has standard cornering lights to illuminate around corners when the turn signals are activated. The Hummer EV SUV doesn’t offer cornering lights.

The Lyriq offers optional massaging front seats in order to maximize comfort and eliminate fatigue on long trips. Massaging seats aren’t available in the Hummer EV SUV.

The Lyriq’s Enhanced Automatic Park Assist can parallel park or back into a parking spot by itself, starting, stopping and changing direction automatically. Remote Auto Parking 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.

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

The Cadillac Lyriq outsold the GMC Hummer EV by over two to one during 2024.
