Compare the2025 Mercedes GLAVS 2025 Cadillac XT4

The GLA’s pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The XT4 doesn’t offer pre-crash pretensioners.

The GLA offers an optional Post Collision Brake, which automatically applies the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The XT4 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.

The GLA’s driver alert monitor detects an inattentive driver then sounds a warning and suggests a break. According to the NHTSA, drivers who fall asleep cause about 100,000 crashes and 1500 deaths a year. The XT4 doesn’t offer a driver alert monitor.

Both the GLA and the XT4 have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, front and rear seatbelt pretensioners, front wheel drive, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, blind spot warning systems, rearview cameras, rear cross-path warning, available all wheel drive, lane departure warning systems and around view monitors.

J.D. Power and Associates’ 2024 Initial Quality Study of new car owners surveyed provide the statistics that show that Mercedes vehicles are better in initial quality than Cadillac vehicles. With 8 fewer problems per 100 vehicles, JD Power ranks Mercedes higher than Cadillac.

As tested in Consumer Reports the Mercedes GLA is faster than the Cadillac XT4:

On the EPA test cycle the GLA gets better mileage than the XT4:

Regenerative brakes improve the GLA’s fuel efficiency by converting inertia back into energy instead of wasting it. The XT4 doesn’t offer a regenerative braking system.

The GLA has a standard locking fuel door which locks and unlocks with the power locks. The fuel filler door is not lockable on the XT4. A locking fuel door helps prevent fuel theft and vandalism, such as sugar in the tank.

The GLA offers a standard sequential manual gearbox (SMG). With no clutch pedal to worry about and a fully automatic mode, an SMG is much more efficient than a conventional automatic but just as easy to drive. The XT4 doesn’t offer an SMG or a conventional manual transmission.

The GLA stops shorter than the XT4:

The GLA’s standard tires provide better handling because they have a lower 55 series profile (height to width ratio) that provides a stiffer sidewall than the XT4’s standard 60 series tires.

Changing a flat tire near traffic can be dangerous and inconvenient. The run-flat tires available on the GLA can be driven up to 50 miles without any air pressure, allowing you to drive to a service station for a repair. The XT4 doesn’t offer run-flat tires.

The GLA’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 XT4 doesn’t offer drift compensation steering.

For better maneuverability, the GLA’s turning circle is .6 feet tighter than the XT4’s (37.4 feet vs. 38 feet).

The Mercedes GLA may be more efficient, handle and accelerate better because it weighs about 300 to 400 pounds less than the Cadillac XT4.

The GLA is 7.3 inches shorter than the XT4, making the GLA easier to handle, maneuver and park in tight spaces.

The GLA has 2.8 inches more front hip room and 7.5 inches more rear hip room than the XT4.

For enhanced passenger comfort on long trips the GLA’s rear seats recline. The XT4’s rear seats don’t recline.

The GLA has a larger cargo volume with its rear seat folded than the XT4 with its rear seat folded (50.5 vs. 48.9 cubic feet).

Unlike the driver-only memory system in the XT4, the GLA has standard driver and passenger memory, so that when drivers switch, the memory setting adjusts the driver’s seat and outside mirror angle and the front passenger seat also adjusts to the new passenger’s preset preferences.

The GLA’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 XT4’s rear power window switches have to be held the entire time to close them fully.

If the windows are left open on the GLA 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 lower the windows from a distance using the keyless remote. The driver of the XT4 can only close the windows from inside the vehicle, with the ignition on.

Heated windshield washer fluid is optional on the GLA to defrost the washer nozzles and quickly clear ice and frost from the windshield without scraping. The XT4 doesn’t offer heated windshield washer fluid.

The XT4’s optional cornering lamps activate a lamp on the front corner when the turn signal is activated. The GLA’s optional adaptive cornering lights turn the actual headlight unit up to several degrees, depending on steering wheel angle and vehicle speed. This lights a significant distance into corners at any speed.

To quickly and conveniently keep personal devices charged without cables tangling and wearing out, the Mercedes GLA has a standard wireless phone charging system (Qi) in the center console. Wireless charging costs extra on the XT4.

The GLA offers an optional 115-volt a/c outlet on the center console, allowing you to recharge a laptop or run small household appliances without special adapters that can break or get misplaced. The XT4 doesn’t offer a house-current electrical outlet.

The GLA’s Active Parking Assist can parallel park or back into a parking spot by itself, starting, stopping and changing direction automatically. The XT4 doesn’t offer an automated parking system.
