Safety

The UX Series has standard Whiplash Injury Lessening Front Seatbacks, which use a specially designed seat to protect the driver and front passenger from whiplash. During a rear-end collision, the Whiplash Injury Lessening Front Seatbacks system allows the backrest to travel backwards to cushion the occupants and the headrests move forward to prevent neck and spine injuries. The GLA doesn’t offer a whiplash protection system.

The UX Series has standard Secondary Collision Brake, which automatically apply the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The GLA 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.

Over 200 people are killed each year when backed over by motor vehicles. The UX Series offers optional Parking Support Brake that uses rear sensors to monitor and automatically apply the brakes to prevent a rear collision. The GLA doesn’t offer backup collision prevention brakes.

To help make backing safer, the UX Series’ optional cross-path warning system uses wide-angle radar in the rear bumper to alert the driver to vehicles approaching from the side, helping the driver avoid collisions. The GLA doesn’t offer a cross-path warning system.

Compared to metal, the UX Series’ plastic fuel tank can withstand harder, more intrusive impacts without leaking; this decreases the possibility of fire. The Mercedes GLA has a metal gas tank.

Both the UX Series and the GLA have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger knee airbags, side-impact head airbags, front and rear seatbelt pretensioners, front wheel drive, height adjustable front shoulder belts, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, rearview cameras, driver alert monitors, available blind spot warning systems and rear parking sensors.

Warranty

Lexus’ powertrain warranty covers the UX Series 2 years and 20,000 miles longer than Mercedes covers the GLA. Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 6 years or 70,000 miles. Coverage on the GLA ends after only 4 years or 50,000 miles.

The UX Series’ corrosion warranty is 1 year longer than the GLA’s (6 vs. 5 years).

Regenerative brakes improve the UX 250h’s fuel efficiency by converting inertia back into energy instead of wasting it. The GLA doesn’t offer a regenerative braking system.

To lower fuel costs and make buying fuel easier, the Lexus UX Series uses regular unleaded gasoline. The GLA requires premium, which can cost 20 to 55 cents more per gallon.

Transmission

The UX Series 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.

Tires and Wheels

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

Suspension and Handling

For better maneuverability, the UX Series’ turning circle is 1.8 feet tighter than the GLA 250’s (34.2 feet vs. 36 feet). The UX Series’ turning circle is 1.9 feet tighter than the AMG GLA 45’s (34.2 feet vs. 36.1 feet).

Passenger Space

The UX Series has 1.9 inches more front legroom, .9 inches more rear headroom and 6 inches more rear legroom than the GLA.

Cargo Capacity

The UX Series has a much larger cargo volume than the GLA with its rear seat up (21.7 vs. 17.2 cubic feet).

Servicing Ease

J.D. Power and Associates surveys of service recipients show that Lexus service is better than Mercedes. J.D. Power ranks Lexus third in service department satisfaction. With a 3% lower rating, Mercedes is ranked 6th.

Ergonomics

The UX Series’ optional easy entry system raises the steering wheel and glides the driver’s seat back when the door is unlocked or the ignition is switched off, making it easier for the driver to get in and out. The GLA doesn’t offer an easy entry system.

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

To improve rear visibility by keeping the rear window clear, the UX Series has a standard rear fixed intermittent wiper with a full on position. The rear wiper standard on the GLA only has an intermittent setting, so in a hard rain visibility isn’t as good.

In poor weather, headlights can lose their effectiveness as grime builds up on their lenses. This can reduce visibility without the driver realizing. The UX Series offers available headlight washers to keep headlight output high. The GLA doesn’t offer headlight washers.

While driving with high beams on, sensitive light sensors standard on the UX Series detect other vehicles which could be blinded and automatically switch to low beams. The GLA doesn’t offer automatic dimming high beams.

To help drivers avoid possible obstacles, the UX Series F SPORT has standard cornering lights to illuminate around corners when the turn signals are activated. The GLA doesn’t offer cornering lights.

To shield the driver and front passenger’s vision over a larger portion of the windshield and side windows, the UX Series has standard extendable sun visors. The GLA doesn’t offer extendable visors.

When the UX Series with available tilt-down mirrors is put in reverse, both rearview mirrors tilt from their original position. This gives the driver a better view of the curb during parallel parking maneuvers. Shifting out of reverse puts the mirrors into their original positions. The GLA’s mirrors don’t automatically adjust for backing.

Optional air-conditioned seats in the UX Series keep the driver and front passenger comfortable and take the sting out of hot seats in summer. The GLA doesn’t offer air-conditioned seats.

On extremely cold winter days, the UX Series’ optional heated steering wheel provides comfort, allowing the driver to steer safely and comfortably before the vehicle heater warms up. The GLA doesn’t offer a heated steering wheel.
