Compare the2024 Infiniti QX50VS 2023 Mercedes GLC

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 QX50 are reminded to check the back seat if they opened the rear door before starting out. The GLC doesn’t offer a back seat reminder.

The Infiniti QX50 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.

The QX50’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 QX50 and the GLC 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, available all wheel drive and around view monitors.

The QX50 comes with a full 4-year/60,000-mile basic warranty, which covers the entire truck and includes 24-hour roadside assistance. The GLC’s 4-year/50,000-mile basic warranty expires 10,000 miles sooner.

Infiniti’s powertrain warranty covers the QX50 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.

The QX50’s corrosion warranty is 2 years longer than the GLC’s (7 vs. 5 years).

Infiniti pays for scheduled maintenance on the QX50 for 3 years and 24,000 miles. Infiniti 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 QX50’s 2.0 turbo 4-cylinder produces 13 more horsepower (268 vs. 255) than the GLC’s 2.0 turbo 4-cylinder hybrid.

The QX50 has a standard continuously variable transmission (CVT). With no “steps” between gears, it can keep the engine at the most efficient speed for fuel economy, or keep it at its peak horsepower indefinitely for maximum acceleration. The GLC doesn’t offer a CVT.

The QX50’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 QX50 has standard 19-inch wheels. Smaller 18-inch wheels are standard on the GLC.

The QX50 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.

Changing a flat tire near traffic can be dangerous and inconvenient. The run-flat tires standard on the QX50 can be driven up to 50 miles without any air pressure, allowing you to drive to a service station for a repair. The GLC doesn’t offer run-flat tires.

The QX50 AWD executes Motor Trend’s “Figure Eight” maneuver quicker than the GLC 300 4MATIC (26.7 seconds @ .66 average G’s vs. 27.3 seconds @ .65 average G’s).

For better maneuverability, the QX50’s turning circle is 2.3 feet tighter than the GLC’s (36.4 feet vs. 38.7 feet).

The Infiniti QX50 may be more efficient, handle and accelerate better because it weighs about 100 to 300 pounds less than the Mercedes GLC.

To almost totally eliminate engine vibration in the passenger area, the QX50 has an electronically controlled liquid-filled front 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 design of the Infiniti QX50 amounts to more than styling. The QX50 has an aerodynamic coefficient of drag of .32 Cd. That is significantly lower than the GLC (.39) and many sports cars. A more efficient exterior helps keep the interior quieter and helps the QX50 get better fuel mileage.

The QX50 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 QX50 has .6 inches more front shoulder room, 1.3 inches more rear legroom and .5 inches more rear shoulder room than the GLC.

The QX50 has a much larger cargo volume with its rear seat up than the GLC with its rear seat up (31.4 vs. 21.9 cubic feet). The QX50 has a much larger cargo volume with its rear seat folded than the GLC with its rear seat folded (65.1 vs. 59.3 cubic feet).

J.D. Power and Associates surveys of service recipients show that Infiniti service is better than Mercedes. J.D. Power ranks Infiniti 9th in service department satisfaction (above the industry average). With a 13% lower rating, Mercedes is ranked 18th.

The QX50 has a standard remote vehicle starting system, so the vehicle can be started from inside the driver's house. This allows the driver to comfortably warm up the engine before going out to the vehicle. The climate system will also automatically heat or cool the interior. The GLC doesn’t offer a remote starting system.

To improve rear visibility by keeping the rear window clear, the QX50 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.
