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

To help make backing safer, the MDX’s optional cross-path warning system uses wide-angle radar in the rear bumper to alert the driver to vehicles approaching from the side, helping the driver avoid collisions. The GLB doesn’t offer a cross-path warning system.

Both the MDX and the GLB have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, front 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, rearview cameras, available all wheel drive, blind spot warning systems and around view monitors.

For its top level performance in all IIHS frontal, side, rear impact and roof-crush tests, its standard front crash prevention system, and its headlight’s “Acceptable” rating, the Insurance Institute for Highway Safety grants the MDX the rating of “Top Pick” for 2018, a rating granted to only 153 vehicles tested by the IIHS. The GLB has not been tested, yet.

The MDX’s standard 3.5 SOHC V6 produces 69 more horsepower (290 vs. 221) and 9 lbs.-ft. more torque (267 vs. 258) than the GLB’s 2.0 turbo 4-cylinder.

An engine control system that can shut down some of the engine’s cylinders helps improve the MDX’s fuel efficiency. The GLB doesn’t offer a system that can shut down part of the engine.

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

The MDX Sport Hybrid’s standard fuel tank has 3.5 gallons more fuel capacity than the GLB (19.4 vs. 15.9 gallons), for longer range between fill-ups. The MDX’s standard fuel tank has 3.6 gallons more fuel capacity than the GLB (19.5 vs. 15.9 gallons).

The MDX has a standard cap-less fueling system. The fuel filler is automatically opened when the fuel nozzle is inserted and automatically closed when it’s removed. This eliminates the need to unscrew and replace the cap and it reduces fuel evaporation, which causes pollution. The GLB doesn’t offer a cap-less fueling system.

For better traction, the MDX has larger standard tires than the GLB (245/60R18 vs. 235/55R18). The MDX A-Spec’s tires are larger than the largest tires available on the GLB (265/45R20 vs. 235/55R18).

The MDX A-Spec’s tires provide better handling because they have a lower 45 series profile (height to width ratio) that provides a stiffer sidewall than the GLB’s optional 50 series tires.

The MDX has a standard easy tire fill system. When inflating the tires, the vehicle’s integrated tire pressure sensors keep track of the pressure as the tires fill and tell the driver when the tires are inflated to the proper pressure. The GLB doesn’t offer vehicle monitored tire inflation.

To improve rear visibility by keeping the rear window clear, the MDX has a standard rear fixed intermittent wiper with a full on position. The rear wiper standard on the GLB only has an intermittent setting, so in a hard rain visibility isn’t as good.

Manual rear side window sunshades are available in the MDX to help block heat and glare for the rear passengers. The GLB doesn’t offer rear side window sunshades.

The MDX has standard heated front seats. Heated front seats cost extra on the GLB. The MDX also offers optional heated second row seats to keep those passengers extremely comfortable in the winter. Heated second row seats aren’t available in the GLB.

The MDX SH-AWD 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 GLB doesn’t offer a house-current electrical outlet.
