Compare the2024 Acura RDXVS 2024 Mercedes GLC

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 GLC doesn’t offer a front passenger side knee airbag.

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

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 GLC.

Both the RDX and the GLC 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, 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 and available around view monitors.

Acura’s powertrain warranty covers the RDX 2 years and 20,000 miles longer than Mercedes covers the GLC. Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 6 years or 70,000 miles. Coverage on the GLC 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 GLC.

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

To lower fuel costs and make buying fuel easier, the Acura RDX uses regular unleaded gasoline (premium recommended for maximum performance). The GLC 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 GLC 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 GLC.

The RDX stops shorter than the GLC:

The RDX’s standard tires provide better handling because they have a lower 55 series profile (height to width ratio) that provides a stiffer sidewall than the GLC’s standard 60 series tires.

For better ride, handling and brake cooling the RDX has standard 19-inch wheels. Smaller 18-inch wheels are standard on the GLC.

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 GLC doesn’t offer vehicle monitored tire inflation.

The RDX offers an available driver-adjustable suspension system. It allows the driver to choose between an extra-supple ride, reducing fatigue on long trips, or a sport setting, which allows maximum control for tricky roads or off-road. The GLC’s suspension doesn’t offer adjustable shock absorbers.

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 GLC 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 GLC doesn’t offer active noise cancellation.

The RDX has .9 inches more front legroom, 2.4 inches more front shoulder room and 1 inch more rear legroom than the GLC.

The RDX has a much larger cargo volume with its rear seat up than the GLC with its rear seat up (31.1 vs. 21.9 cubic feet). The RDX has a much larger cargo volume with its rear seat folded than the GLC with its rear seat folded (79.8 vs. 56.3 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 GLC 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 GLC’s headlights, which were rated “Fair.”
