For enhanced safety, the front and rear seat shoulder belts of the Mercedes GLA have pretensioners to tighten the seatbelts and eliminate dangerous slack in the event of a collision and force limiters to limit the pressure the belts will exert on the passengers. The Hyundai Tucson doesn’t offer pretensioners for the rear seat belts.

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 Tucson doesn’t offer pre-crash pretensioners.

The GLA has a standard Post Collision Brake, which automatically applies the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The Tucson doesn’t offer a post collision braking system: in the event of a collision that triggers the airbags, more collisions are possible without the protection of airbags that may have already deployed.

Both the GLA and the Tucson have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front wheel drive, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, rearview cameras, driver alert monitors, available all wheel drive, lane departure warning systems and around view monitors.

In heavy traffic or at stoplights the GLA’s engine automatically turns off when the vehicle is stopped, saving fuel and reducing pollution. The engine is automatically restarted when the driver gets ready to move again. (Start/Stop isn’t accounted in present EPA fuel mileage tests.) The Tucson doesn’t offer an automatic engine start/stop system.

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

The GLA offers a standard sequential manual gearbox (SMG). With no clutch pedal to worry about and a fully automatic mode, an SMG is much more efficient than a conventional automatic but just as easy to drive. The Tucson doesn’t offer an SMG or a conventional manual transmission.

Tires and Wheels

For better traction, the GLA has larger tires than the Tucson (235/55R18 vs. 225/60R17).

The GLA’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 Tucson SE/Value’s standard 60 series tires.

For better ride, handling and brake cooling the GLA has standard 18-inch wheels. Smaller 17-inch wheels are standard on the Tucson SE/Value. The GLA’s optional 20-inch wheels are larger than the 19-inch wheels on the Tucson Sport.

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 Tucson doesn’t offer run-flat tires.

The GLA offers an optional 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 Tucson’s suspension doesn’t offer adjustable shock absorbers.

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 Tucson doesn’t offer drift compensation steering.

For a smoother ride and more stable handling, the GLA’s wheelbase is 2.3 inches longer than on the Tucson (107.4 inches vs. 105.1 inches).

The design of the Mercedes GLA amounts to more than styling. The GLA has an aerodynamic coefficient of drag of .3 Cd. That is lower than the Tucson (.33) and many sports cars. A more efficient exterior helps keep the interior quieter and helps the GLA get better fuel mileage.

The front grille of the GLA uses electronically controlled shutters to close off airflow and reduce drag when less engine cooling is needed. This helps improve highway fuel economy. The Tucson doesn’t offer active grille shutters.

A standard locking glovebox (which can’t be accessed with the valet key) keeps your small valuables safer in the GLA. The Tucson doesn’t offer locking storage for small valuables.

The GLA uses gas struts to support the hood for easier service access. The Tucson uses a prop rod to support its heavy hood. It takes two hands to open the hood and set the prop rod, the prop rod gets in the way during maintenance and service, and the prop rod could be knocked out, causing the heavy hood to fall on the person maintaining or servicing the car.

J.D. Power and Associates surveys of service recipients show that Mercedes service is better than Hyundai. J.D. Power ranks Mercedes fifth in service department satisfaction. With a 52% lower rating, Hyundai is ranked 22nd.

When three different drivers share the GLA, the memory seats and mirrors make it convenient for all three. Each setting activates different, customized memories for the driver and front passenger’s seat positions and outside mirror angle. The Tucson doesn’t offer a memory 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. The Tucson doesn’t offer an easy entry system.

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 Tucson doesn’t offer a heads-up display.

The GLA’s front and rear power windows all open or close fully with one touch of the switches, making it more convenient at drive-up windows and toll booths, or when talking with someone outside the car. The Tucson’s standard power window switches have to be held the entire time to close them fully. Only its driver’s window opens automatically.

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 Tucson can only operate the windows from inside the vehicle, with the ignition on.

The GLA’s rain-sensitive wipers adjust their speed and turn on and off automatically based on the amount of rainfall on the windshield. This allows the driver to concentrate on driving without constantly adjusting the wipers. The Tucson’s standard manually variable intermittent wipers have to be constantly adjusted.

The GLA’s standard outside mirrors include heating elements to clear off the mirrors for better visibility. Hyundai only offers heated mirrors on the Tucson Value/SEL/Sport/Limited/Ultimate.

When the GLA is put in reverse, the passenger rearview mirror tilts from its original position. This gives the driver a better view of the curb during parallel parking maneuvers. Shifting out of reverse puts the mirror into its original position. The Tucson’s mirror doesn’t automatically adjust for backing.

The GLA’s optional rear and side view mirrors have an automatic dimming feature. These mirrors can be set to automatically darken quickly when headlights shine on them, keeping following vehicles from blinding or distracting the driver. The Tucson offers an automatic rear view mirror, but its side mirrors don’t dim.

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 Tucson.

The GLA has a standard dual zone air conditioning allows the driver and front passenger to choose two completely different temperatures so people with different temperature preferences won’t have to compromise. This makes both the driver and front passenger as comfortable as possible. Dual zone air conditioning is only available on the Tucson SEL/Sport/Limited/Ultimate.

Both the GLA and the Tucson offer rear vents. For greater rear passenger comfort, the GLA has standard rear air conditioning vents to keep rear occupants cool in summer or warm in winter. The Tucson doesn’t offer rear air conditioning vents, only heat vents.

The GLA has a 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 Tucson 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 Tucson doesn’t offer an automated parking system.
