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 Lexus NX Series doesn’t offer pretensioners for the rear seat belts.

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

There are over 58 percent more Mercedes dealers than there are Lexus dealers, which makes it much easier should you ever need service under the GLA’s warranty.

The GLA’s 2.0 turbo 4-cylinder produces 27 more horsepower (221 vs. 194) and 59 lbs.-ft. more torque (258 vs. 199) than the NX 300h’s standard 2.5 DOHC 4-cylinder hybrid.

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 NX Series.

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 NX Series doesn’t offer an SMG or a conventional manual transmission.

Tires and Wheels

For better traction, the GLA has larger tires than the NX Series (235/55R18 vs. 225/65R17).

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 NX Series’ standard 65 series tires. The GLA’s optional tires have a lower 50 series profile than the NX Series F Sport’s 55 series tires.

For better ride, handling and brake cooling the GLA has standard 18-inch wheels. Smaller 17-inch wheels are standard on the NX Series. The GLA’s optional 20-inch wheels are larger than the 18-inch wheels optional on the NX Series.

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 NX Series 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 NX Series doesn’t offer drift compensation steering.

For a smoother ride and more stable handling, the GLA’s wheelbase is 2.7 inches longer than on the NX Series (107.4 inches vs. 104.7 inches).

For better handling and stability, the track (width between the wheels) on the GLA is 1.2 inches wider in the front and 1.2 inches wider in the rear than the average track on the NX Series.

The Mercedes GLA may be more efficient, handle and accelerate better because it weighs about 550 to 700 pounds less than the Lexus NX Series.

The GLA is 9.1 inches shorter than the NX Series, 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 NX Series (.34) 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 NX Series doesn’t offer active grille shutters.

Unlike the driver-only memory system optional at extra cost in the NX Series, the GLA has standard driver and passenger memory, so that when drivers switch, the memory setting adjusts the driver’s seat and outside mirror angle and the front passenger seat also adjusts to the new passenger’s preset preferences.

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 NX Series.

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 NX Series doesn’t offer a heads-up display.

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 NX Series’ standard manually variable intermittent wipers have to be constantly adjusted.

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 NX Series.

To quickly and conveniently keep personal devices charged without cables tangling and wearing out, the Mercedes GLA offers an optional wireless phone charging system (Qi) in the center console. The NX Series doesn’t offer wireless personal charging.

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 NX Series 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 NX Series doesn’t offer an automated parking system.
