Compare the2024 Mazda CX-30VS 2023 Mercedes GLA

For enhanced safety, the front seat shoulder belts of the Mazda CX-30 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 CX-30 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 Mazda CX-30 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 CX-30 Turbo Premium Plus has standard Rear Smart Brake Support that use rear sensors to monitor for objects to the rear and automatically apply the brakes to prevent a collision. The GLA doesn’t offer automatic braking for stationary objects directly to the rear.

To provide maximum traction and stability on all roads, All-Wheel Drive is standard on the CX-30. But it costs extra on the GLA.

The CX-30’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 CX-30 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, 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 and available around view monitors.

For its performance in IIHS driver-side and passenger-side small overlap frontal, moderate overlap frontal, updated side impact, headlight, daytime pedestrian crash prevention, and nighttime pedestrian crash prevention testing, the Insurance Institute for Highway Safety grants the CX-30 its highest rating: “Top Safety Pick Plus” for 2023, a rating granted to only 58 vehicles tested by the IIHS. The GLA has not been tested, yet.

Mazda’s powertrain warranty covers the CX-30 1 year and 10,000 miles longer than Mercedes covers the GLA. Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 5 years or 60,000 miles. Coverage on the GLA ends after only 4 years or 50,000 miles.

There are over 41 percent more Mazda dealers than there are Mercedes dealers, which makes it easier should you ever need service under the CX-30’s warranty.

The CX-30 stops shorter than the GLA:

The CX-30 has a standard space-saver spare tire so you can replace a flat tire and drive to have the flat repaired or replaced. A spare tire isn’t available on the GLA; it requires you to depend on its run-flat tires, which limits mileage and speed before they are repaired. If a run-flat is damaged beyond repair by a road hazard your vehicle will have to be towed. Some tire options on the GLA don’t have a run-flat feature, either.
