Compare the2023 Mercedes GLAVS 2022 Porsche Macan

The GLA’s pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The Macan doesn’t offer pre-crash pretensioners.

The GLA’s standard pretensioning seatbelts also sense rear collisions and remove slack from the seatbelts to help protect the occupants from whiplash and other injuries. The Macan doesn’t offer a whiplash protection system.

The GLA has a standard blind spot warning system which uses sensors to alert the driver to objects in the vehicle’s blind spots where the side view mirrors don’t reveal them. A system to reveal vehicles in the Macan’s blind spot costs extra.

To help make backing out of a parking space safer, the GLA’s standard rear cross-path warning system uses sensors in the rear bumper to alert the driver to vehicles approaching from the side, helping the driver avoid collisions. The Macan doesn’t offer a cross-path warning system.

The GLA’s driver alert monitor detects an inattentive driver then sounds a warning and suggests a break. According to the NHTSA, drivers who fall asleep cause about 100,000 crashes and 1500 deaths a year. The Macan doesn’t offer a driver alert monitor.

Both the GLA and the Macan 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, daytime running lights, rearview cameras, available all wheel drive, lane departure warning systems and around view monitors.

There are almost 2 times as many Mercedes dealers as there are Porsche dealers, which makes it much easier should you ever need service under the GLA’s warranty.

J.D. Power and Associates’ 2022 Initial Quality Study of new car owners surveyed provide the statistics that show that Mercedes vehicles are better in initial quality than Porsche vehicles. With 11 fewer problems per 100 vehicles, JD Power ranks Mercedes higher than Porsche.

On the EPA test cycle the GLA gets better mileage than the Macan:

An eight-speed automatic (SMG) is standard on the Mercedes GLA, for better acceleration and lower engine speed on the highway. Only a seven-speed automatic is available for the Macan.

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

The GLA’s drift compensation steering can automatically compensate for road conditions which would cause the vehicle to drift from side to side, helping the driver to keep the vehicle straight more easily. The Macan doesn’t offer drift compensation steering.

For better maneuverability, the GLA’s turning circle is 1.8 feet tighter than the Macan’s (37.4 feet vs. 39.2 feet).

The Mercedes GLA may be more efficient, handle and accelerate better because it weighs about 750 to 900 pounds less than the Porsche Macan.

The GLA is 1 foot shorter than the Macan, making the GLA easier to handle, maneuver and park in tight spaces.

The design of the Mercedes GLA amounts to more than styling. The GLA has an aerodynamic coefficient of drag of .3 Cd. That is significantly lower than the Macan (.35 to .37) and many sports cars. A more efficient exterior helps keep the interior quieter and helps the GLA get better fuel mileage.

For enhanced passenger comfort on long trips the GLA’s rear seats recline. The Macan’s rear seats don’t recline.

The GLA has a much larger cargo volume than the Macan with its rear seat up (19 vs. 17.2 cubic feet).

To make loading groceries and cargo easier when your hands are full, the GLA’s available liftgate can be opened and closed just by kicking your foot under the back bumper, leaving your hands completely free. The Macan doesn’t offer a hands-free gesture to open its liftgate, forcing you to put cargo down if your hands are full.

The GLA 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 Macan doesn’t offer a remote starting system.

The GLA’s standard easy entry system glides the driver’s seat back, making it easier for the driver to get in and out. An easy entry system costs extra on the Macan.

The GLA offers an optional heads-up display that projects speed and navigation instruction readouts in front of the driver’s line of sight, allowing drivers to view information without diverting their eyes from the road. The Macan doesn’t offer a heads-up display.

If the windows are left open on the GLA the driver can close them all at the outside door handle or from a distance using the remote. On a hot day the driver can lower the windows from a distance using the keyless remote. The driver of the Macan can only operate the windows from inside the vehicle, with the ignition on.

The GLA offers optional massaging front seats in order to maximize comfort and eliminate fatigue on long trips. Massaging seats aren’t available in the Macan.

The GLA offers an optional 115-volt a/c outlet on the center console, allowing you to recharge a laptop or run small household appliances without special adapters that can break or get misplaced. The Macan doesn’t offer a house-current electrical outlet.

The GLA’s optional Active Parking Assist can parallel park or back into a parking spot by itself, starting, stopping and changing direction automatically. The Macan’s automatic parking system requires operating the brakes and transmission to safely park.

The GLA is available in both front-wheel drive and four-wheel drive configurations. The Macan doesn’t offer a two-wheel drive configuration.

Insurance will cost less for the GLA owner. The Complete Car Cost Guide estimates that insurance for the GLA will cost $3230 to $6945 less than the Macan over a five-year period.

IntelliChoice estimates that five-year ownership costs (depreciation, financing, insurance, fuel, fees, repairs and maintenance) for the Mercedes GLA will be $14096 to $31056 less than for the Porsche Macan.

J.D. Power and Associates rated the GLA first among small premium suvs in owner reported satisfaction. This includes how well the vehicle performs and satisfies its owner’s expectations. The Macan was rated third in its category.
