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

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

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

The GLB stops much shorter than the MDX:

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 MDX doesn’t offer drift compensation steering.

The GLB 250 4MATIC handles at .89 G’s, while the MDX Type S pulls only .87 G’s of cornering force in a Car and Driver skidpad test.

For better maneuverability, the GLB’s turning circle is 2.1 feet tighter than the MDX’s (38.4 feet vs. 40.5 feet).

For greater off-road capability the GLB has a greater minimum ground clearance than the MDX (7.9 vs. 7.3 inches), allowing the GLB to travel over rougher terrain without being stopped or damaged.

The Mercedes GLB may be more efficient, handle and accelerate better because it weighs about 650 to 900 pounds less than the Acura MDX.

The GLB is 1 foot, 4 inches shorter than the MDX, making the GLB easier to handle, maneuver and park in tight spaces.

The 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 GLB and the MDX have locks to prevent small children from operating them.

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

The GLB’s standard rear and side view mirrors have an automatic dimming feature. These mirrors can be set to automatically darken quickly when headlights shine on them, keeping following vehicles from blinding or distracting the driver. The MDX has an automatic rear view mirror, but its side mirrors don’t dim.

The GLB’s Active Parking Assist can parallel park by itself, stopping and changing direction automatically. The MDX 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 MDX only retains 50.63% to 53.63%.

IntelliChoice estimates that five-year ownership costs (depreciation, financing, insurance, fuel, fees, repairs and maintenance) for the Mercedes GLB will be $10874 to $30515 less than for the Acura MDX.
