Compare the2024 Acura RDXVS 2024 Mercedes GLE

The Acura RDX 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.

The RDX’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 RDX and the GLE have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, front seatbelt pretensioners, height adjustable front shoulder belts, plastic fuel tanks, four-wheel antilock brakes, all wheel drive, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, blind spot warning systems, rearview cameras, rear cross-path warning and available 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 RDX 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 RDX is safer than the GLE:

Acura’s powertrain warranty covers the RDX 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.

Acura pays for scheduled maintenance on the RDX for 2 years and 24,000 miles. Acura will pay for oil changes, tire rotations, air filter replacements, cabin filter replacement, brake fluid replacement, inspections, and any other required maintenance. Mercedes doesn’t pay scheduled maintenance for the GLE.

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 RDX’s reliability 44 points higher than the GLE.

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.

The RDX’s 2.0 turbo 4-cylinder produces 17 more horsepower (272 vs. 255) than the GLE 350’s standard 2.0 turbo 4-cylinder hybrid.

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

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

To lower fuel costs and make buying fuel easier, the Acura RDX uses regular unleaded gasoline (premium recommended for maximum performance). The GLE requires premium, which can cost on average about 82.8 cents more per gallon.

The RDX 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 RDX, for better acceleration and lower engine speed on the highway. Only a nine-speed automatic is available for the GLE.

The RDX stops much shorter than the GLE:

The RDX 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.

The RDX A-Spec handles at .82 G’s, while the GLE 350 pulls only .78 G’s of cornering force in a Motor Trend skidpad test.

The RDX executes Motor Trend’s “Figure Eight” maneuver 1 seconds quicker than the GLE 350 (27.2 seconds @ .64 average G’s vs. 28.2 seconds @ .62 average G’s).

For greater off-road capability the RDX has a greater minimum ground clearance than the GLE (8.2 vs. 7.9 inches), allowing the RDX to travel over rougher terrain without being stopped or damaged.

The Acura RDX may be more efficient, handle and accelerate better because it weighs about 900 to 1700 pounds less than the Mercedes GLE.

The RDX is 6.9 inches shorter than the GLE, making the RDX easier to handle, maneuver and park in tight spaces.

To almost totally eliminate engine vibration in the passenger area, the RDX has an electronically controlled liquid-filled main engine mount. A computer-controlled electric current in the liquid changes its viscosity, allowing the mount to dampen the engine completely at all RPMs. The GLE uses conventional solid rubber engine mounts.

The RDX 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.

The RDX has 1.3 inches more front legroom, .4 inches more front shoulder room and 1.4 inches more rear headroom than the GLE.

The RDX has a larger cargo volume with its rear seat folded than the GLE with its rear seat folded (79.8 vs. 74.9 cubic feet).

J.D. Power and Associates surveys of service recipients show that Acura service is better than Mercedes. J.D. Power ranks Acura 6th in service department satisfaction (above the industry average). With a 22% lower rating, Mercedes is ranked 18th.

To improve rear visibility by keeping the rear window clear, the RDX 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 RDX’s headlight performance “Good,” a higher rating than the GLE’s headlights, which were rated “Poor.”

Insurance will cost less for the RDX owner. The Complete Car Cost Guide estimates that insurance for the RDX will cost $3210 to $8890 less than the GLE over a five-year period.

The RDX will cost the buyer less in the long run because of its superior resale value. The IntelliChoice estimates that the RDX will retain 53.7% to 55% of its original price after five years, while the GLE only retains 49.45% to 53.48%.

According to The Car Book by Jack Gillis, the RDX is less expensive to operate than the GLE because it costs $146 less to do the manufacturer’s suggested maintenance for 50,000 miles. Typical repairs cost much less on the RDX than the GLE, including $461 less for a water pump, $361 less for a muffler, $142 less for a starter, $326 less for fuel injection, $26 less for a fuel pump, $199 less for front struts and $39 less for a timing belt/chain.

IntelliChoice estimates that five-year ownership costs (depreciation, financing, insurance, fuel, fees, repairs and maintenance) for the Acura RDX will be $19138 to $41189 less than for the Mercedes GLE.
