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 helps 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.

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.
