Compare the2025 Acura MDXVS 2024 Mercedes GLE

In the past twenty years hundreds of infants and young children have died after being left in vehicles, usually by accident. When turning the vehicle off, drivers of the MDX are reminded to check the back seat if they opened the rear door before starting out. The GLE doesn’t offer a back seat reminder.

The Acura MDX has standard driver and front passenger side knee airbags mounted low on the dashboard. These airbags helps prevent the driver and front passenger from sliding under their seatbelts or the main frontal airbags; this keeps them better positioned during a collision for maximum protection. Knee airbags also help keep the legs from striking the dashboard, preventing knee and leg injuries in the case of a serious frontal collision. The GLE doesn’t offer a front passenger side knee airbag.

Over 200 people are killed each year when backed over by motor vehicles. The MDX offers an optional Low-Speed Braking Control that uses rear sensors to monitor for objects to the rear and automatically applies the brakes to prevent a collision. The GLE doesn’t offer automatic braking for stationary objects directly to the rear.

The MDX’s standard lane departure warning system alerts a temporarily inattentive driver when the vehicle begins to leave its lane and gently nudges the vehicle back towards its lane. A lane departure warning system costs extra on the GLE.

Both the MDX and the GLE 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, available all wheel drive and around view monitors.

The National Highway Traffic Safety Administration does side impact tests on new vehicles. In this test, which crashes the vehicle into a flat barrier at 38.5 MPH and into a post at 20 MPH, results indicate that the Acura MDX is safer than the Mercedes GLE:

New test not comparable to pre-2011 test results. More stars = Better. Lower test results = Better.

Side impacts caused 23% of all road fatalities in 2018, down from 29% in 2003, when the Insurance Institute for Highway Safety introduced its side barrier test. In order to continue improving vehicle safety, the IIHS has started using a more severe side impact test: 37 MPH (up from 31 MPH), with a 4180-pound barrier (up from 3300 pounds). The results of this newly developed test demonstrates that the Acura MDX is safer than the GLE:

Acura’s powertrain warranty covers the MDX 2 years and 20,000 miles longer than Mercedes covers the GLE. Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 6 years or 70,000 miles. Coverage on the GLE ends after only 4 years or 50,000 miles.

A reliable vehicle saves its owner time, money and trouble. Nobody wants to be stranded or have to be without a vehicle while it’s being repaired. Consumer Reports rates the MDX’s reliability 15 points higher than the GLE.

J.D. Power and Associates’ 2024 Initial Quality Study of new car owners surveyed provide the statistics that show that Acura vehicles are better in initial quality than Mercedes vehicles. J.D. Power ranks Acura above average in initial quality. With 13 more problems per 100 vehicles, Mercedes is rated below average.

J.D. Power and Associates’ 2024 survey of the owners of three-year-old vehicles provides the long-term dependability statistics that show that Acura vehicles are more reliable than Mercedes With 2 fewer problems per 100 vehicles in the first three years of ownership, J.D. Power ranks Acura higher than Mercedes.

From surveys of all its subscribers, Consumer Reports’ January 2024 Auto Issue reports that Acura vehicles are more reliable than Mercedes vehicles. Consumer Reports ranks Acura fourth in overall reliability. Mercedes is ranked 29th.

As tested in Motor Trend the Acura MDX V6 is faster than the GLE 350 2.0 turbo 4-cylinder:

On the EPA test cycle the MDX gets better mileage than the GLE running its gasoline engine:

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

To lower fuel costs and make buying fuel easier, the Acura MDX uses regular unleaded gasoline (premium recommended for maximum performance). The GLE requires premium, which can cost on average about 84.9 cents more per gallon.

The MDX has 1.3 gallons more fuel capacity than the GLE 450e’s standard fuel tank (18.5 vs. 17.2 gallons), for longer range between fill-ups.

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 GLE doesn’t offer a cap-less fueling system.

A 10-speed automatic is standard on the Acura MDX, for better acceleration and lower engine speed on the highway. Only a nine-speed automatic is available for the GLE.

For better stopping power the MDX’s standard brake rotors are larger than those on the GLE:

The MDX stops shorter than the GLE:

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 GLE doesn’t offer vehicle monitored tire inflation.

For better handling and stability, the track (width between the wheels) on the MDX is 2.1 inches wider in the front and 1.3 inches wider in the rear than on the GLE.

The MDX Type S handles at .87 G’s, while the GLE 450 pulls only .84 G’s of cornering force in a Car and Driver skidpad test.

The MDX Type S executes Motor Trend’s “Figure Eight” maneuver 1.2 seconds quicker than the GLE 350 (27 seconds @ .66 average G’s vs. 28.2 seconds @ .62 average G’s).

For greater off-road capability the MDX Type S has a greater minimum ground clearance than the GLE Airmatic (9.4 vs. 9.2 inches), allowing the MDX to travel over rougher terrain without being stopped or damaged.

The Acura MDX may be more efficient, handle and accelerate better because it weighs about 650 to 1000 pounds less than the Mercedes GLE.

The MDX uses computer-generated active noise cancellation to help remove annoying noise and vibration from the passenger compartment, especially at low frequencies. The GLE doesn’t offer active noise cancellation.

As tested by Car and Driver while at idle, the interior of the MDX Type S is quieter than the GLE 450 (36 vs. 38 dB).

The MDX has 1.3 inches more front legroom, 2.6 inches more front shoulder room, 1.2 inches more rear headroom and 2 inches more rear shoulder room than the GLE.

The MDX’s cargo area provides more volume than the GLE.

A Trailer Stability Assist is standard on the MDX, using the Vehicle Stability Assist sensors to detect trailer sway, then uses individual brakes to counteract any swaying and help keep the tow vehicle and trailer steady. A trailer sway program costs extra on the GLE.

J.D. Power and Associates surveys of service recipients show that Acura service is better than Mercedes. J.D. Power ranks Acura 9th in service department satisfaction (above the industry average). With a 12% lower rating, Mercedes is ranked 17th.

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 GLE only has an intermittent setting, so in a hard rain visibility isn’t as good.

Consumer Reports rated the MDX’s headlight performance “Very Good,” a higher rating than the GLE’s headlights, which were rated “Poor.”

The MDX is available in both front-wheel drive and four-wheel drive configurations. The GLE doesn’t offer a two-wheel drive configuration.

Insurance will cost less for the MDX owner. The Complete Car Cost Guide estimates that insurance for the MDX will cost $1955 to $7930 less than the GLE over a five-year period.

IntelliChoice estimates that five-year ownership costs (depreciation, financing, insurance, fuel, fees, repairs and maintenance) for the Acura MDX will be $10856 to $17855 less than for the Mercedes GLE.

Consumer Reports® recommends the Acura MDX, based on reliability, safety and performance. The Mercedes GLE isn't recommended.
