Compare the2024 Infiniti QX50VS 2023 Mercedes GLA

For enhanced safety, the front seat shoulder belts of the Infiniti QX50 are height-adjustable to accommodate a wide variety of driver and passenger heights. A better fit can prevent injuries and the increased comfort also encourages passengers to buckle up. The Mercedes GLA doesn’t offer height-adjustable seat belts.

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

Over 200 people are killed each year when backed over by motor vehicles. The QX50 has standard Rear Automatic Braking that uses rear sensors to monitor for objects to the rear and automatically applies the brakes to prevent a collision. The GLA doesn’t offer automatic braking for stationary objects directly to the rear.

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 GLA.

Both the QX50 and the GLA have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, front and rear seatbelt pretensioners, front wheel drive, 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.

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 GLA.

In its Green Vehicle Guide, the U.S. Environmental Protection Agency (EPA) rates the Infiniti QX50 higher (6 out of 10) than the Mercedes GLA (5). This means the QX50 produces up to 6.9 pounds less smog-producing pollutants than the GLA every 15,000 miles.

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 GLA doesn’t offer a CVT.

For better stopping power the QX50’s brake rotors are larger than those on the GLA:

The QX50’s standard front and rear disc brakes are vented to help dissipate heat for shorter stops with less fading. The rear discs on the GLA are solid, not vented.

For better ride, handling and brake cooling the QX50 has standard 19-inch wheels. Smaller 18-inch wheels are standard on the GLA.

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 GLA 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. Run-flat tires aren’t available on some tire packages on the GLA.

The QX50 AWD executes Motor Trend’s “Figure Eight” maneuver 1.1 seconds quicker than the GLA 250 4MATIC (26.7 seconds @ .66 average G’s vs. 27.8 seconds @ .61 average G’s).

For better maneuverability, the QX50’s turning circle is 1 foot tighter than the GLA’s (36.4 feet vs. 37.4 feet).

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 GLA uses conventional solid rubber engine mounts.

The QX50 uses computer-generated active noise cancellation to help remove annoying noise and vibration from the passenger compartment, especially at low frequencies. The GLA doesn’t offer active noise cancellation.
