Compare the2025 Mercedes GLBVS 2025 Cadillac XT4

The GLB’s optional 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 GLB’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 GLB 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, height adjustable front shoulder belts, 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 Motor Trend the Mercedes GLB is faster than the Cadillac XT4:

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

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

The GLB 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 GLB 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.

For better stopping power the GLB’s brake rotors are larger than those on the XT4:

The GLB’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 GLB 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 GLB’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 a smoother ride and more stable handling, the GLB’s wheelbase is 2 inches longer than on the XT4 (111.4 inches vs. 109.4 inches).

The GLB 250 4MATIC handles at .83 G’s, while the XT4 Sport AWD pulls only .81 G’s of cornering force in a Motor Trend skidpad test.

For greater off-road capability the GLB has a 1.2 inches greater minimum ground clearance than the XT4 (7.9 vs. 6.7 inches), allowing the GLB to travel over rougher terrain without being stopped or damaged.

The GLB offers optional seating for 7 passengers; the XT4 can only carry 5.

The GLB has 1.3 inches more front headroom and 1 inch more rear headroom than the XT4.

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

The GLB’s cargo area provides more volume than the XT4.

A low lift-over cargo hatch design makes loading and unloading the GLB easier. The GLB’s cargo hatch lift-over height is 28.5 inches, while the XT4’s liftover is 30.5 inches.

The GLB’s cargo area is larger than the XT4’s in almost every dimension:

Unlike the driver-only memory system in the XT4, the GLB has standard driver and passenger memory, so that when drivers switch, the memory setting adjusts the driver’s seat, suspension setting, power steering assist, outside mirror angle, climate settings and radio stations and the front passenger seat also adjusts to the new passenger’s preset preferences.

The GLB’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 GLB 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 nozzles are optional on the GLB to prevent washer fluid and nozzles from freezing and help continue to keep the windshield clear in sub-freezing temperatures. The XT4 doesn’t offer heated windshield washer nozzles.

The XT4’s optional cornering lamps activate a lamp on the front corner when the turn signal is activated. The GLB’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 GLB has a standard wireless phone charging system (Qi) in the center console. Wireless charging costs extra on the XT4.

The GLB 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 GLB’s Active Parking Assist can parallel park by itself, stopping and changing direction automatically. The XT4 doesn’t offer an automated parking system.

The GLB will cost the buyer less in the long run because of its superior resale value. The IntelliChoice estimates that the GLB will retain 61.32% of its original price after five years, while the XT4 only retains 52.41% to 53.95%.
