Compare the2025 Mercedes AMG GLBVS 2025 Acura MDX

The AMG 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 MDX doesn’t offer pre-crash pretensioners.

The AMG GLB 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 MDX 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.

To provide maximum traction and stability on all roads, All-Wheel Drive is standard on the AMG GLB. But it costs extra on the MDX.

When descending a steep, off-road slope, the AMG GLB’s standard Downhill Speed Regulation allows you to creep down safely. The MDX doesn’t offer Downhill Speed Regulation.

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

Both the AMG GLB and the MDX have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, front and rear seatbelt pretensioners, 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, driver alert monitors and available lane departure warning systems.

There are over 41 percent more Mercedes dealers than there are Acura dealers, which makes it easier should you ever need service under the AMG GLB’s warranty.

A hardened steel chain, with no maintenance needs, drives the camshafts in the AMG GLB’s engine. A rubber cam drive belt that needs periodic replacement drives the MDX’s camshafts. If the MDX’s belt breaks, the engine could be severely damaged when the pistons hit the opened valves.

The AMG GLB’s 2.0 turbo 4-cylinder hybrid produces 12 more horsepower (302 vs. 290) and 28 lbs.-ft. more torque (295 vs. 267) than the MDX’s standard 3.5 SOHC V6.

As tested in Car and Driver the Mercedes AMG GLB is faster than the Acura MDX:

On the EPA test cycle the AMG GLB gets better mileage than the MDX:

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

In its Green Vehicle Guide, the U.S. Environmental Protection Agency (EPA) rates the Mercedes AMG GLB higher (5 out of 10) than the Acura MDX (4). This means the AMG GLB produces up to 5.2 pounds less smog-producing pollutants than the MDX every 15,000 miles.

The AMG 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 MDX doesn’t offer an SMG or a conventional manual transmission.

The AMG GLB’s launch control uses engine electronics to hold engine RPM’s precisely in order to provide the most stable and rapid acceleration possible, using all of the available traction. The MDX doesn’t offer launch control.

The AMG GLB’s standard front and rear disc brakes are vented to help dissipate heat for shorter stops with less fading. The rear discs on the MDX are solid, not vented.

The AMG GLB stops much shorter than the MDX:

The AMG GLB’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 MDX’s standard 55 series tires. The AMG GLB’s optional tires have a lower 35 series profile than the MDX Type S’ 40 series tires.

The AMG 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 MDX doesn’t offer drift compensation steering.

The Mercedes AMG GLB may be more efficient, handle and accelerate better because it weighs about 400 to 900 pounds less than the Acura MDX.

The AMG GLB is 1 foot, 3.3 inches shorter than the MDX, making the AMG GLB easier to handle, maneuver and park in tight spaces.

The AMG GLB is 5.9 inches narrower than the MDX, making the AMG GLB easier to handle and maneuver in traffic.

The AMG GLB has 2.2 inches more front headroom and 1.2 inches more rear headroom than the MDX.

The power windows standard on both the AMG GLB and the MDX have locks to prevent small children from operating them. When the lock on the AMG GLB is engaged the driver can still operate all of the windows, for instance to close one opened by a child. The MDX prevents the driver from operating the other windows just as it does the other passengers.

The AMG GLB’s standard Keyless-Go allow you to unlock the doors from any outside door handle, open the cargo door, and start the engine, all without removing the key from the pocket or purse. Keyless Access System standard on the MDX doesn’t offer a sensor on the rear doors, so you’ll have to reach a front handle to unlock the rear door.

The AMG GLB’s rain-sensitive wipers adjust their speed and turn on and off automatically based on the amount of rainfall on the windshield. This allows the driver to concentrate on driving without constantly adjusting the wipers. The MDX’s standard intermittent wipers change speed with vehicle speed, but can’t turn on and off or change speed based on changing rainfall.

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

To help drivers avoid possible obstacles, the AMG GLB offers optional cornering lights to illuminate around corners when the turn signals are activated. The MDX doesn’t offer cornering lights. The AMG GLB also offers optional adaptive headlights to illuminate around corners automatically by reading vehicle speed and steering wheel angle.

The Mercedes AMG GLB has power folding mirrors that offer unparalleled convenience while maneuvering in tight places or parked. With the mirrors folded it’s easier to walk past and help prevent parking damage. The mirrors can be quickly unfolded when the driver is ready to leave. Power folding mirrors costs extra on the MDX.

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

The AMG GLB will cost the buyer less in the long run because of its superior resale value. The IntelliChoice estimates that the AMG GLB will retain 54.15% of its original price after five years, while the MDX only retains 50.63% to 53.63%.
