The XC40’s pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The GLA doesn’t offer pre-crash pretensioners.

Both the XC40 and GLA have child safety locks to prevent children from opening the rear doors. The XC40 has power child safety locks, allowing the driver to activate and deactivate them from the driver's seat and to know when they're engaged. The GLA’s child locks have to be individually engaged at each rear door with a manual switch. The driver can’t know the status of the locks without opening the doors and checking them.

The XC40 has a standard Whiplash Protection System (WHIPS), which use a specially designed seat to protect the driver and front passenger from whiplash. During a rear-end collision, the WHIPS allows the backrest to travel backwards to cushion the occupants and the headrests move forward to prevent neck and spine injuries. At the same time the pretensioning seatbelts fire, removing slack from the belts. The GLA doesn’t offer a whiplash protection system.

The XC40 has standard Automatic Braking After Collision, 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 XC40 offers an optional CTA Auto Brake that use 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 XC40’s 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.

Both the XC40 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, 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 and available around view monitors.

For its top level performance in IIHS driver and passenger-side small overlap frontal, moderate overlap frontal, side impact, roof strength and head restraint tests, its standard vehicle-to-vehicle front crash prevention system, its standard vehicle-to-pedestrian front crash prevention system, and its available headlight’s “Good” rating, the Insurance Institute for Highway Safety grants the XC40 the rating of “Top Pick” for 2020, a rating granted to only 32 vehicles tested by the IIHS. The GLA has not been tested, yet.

The XC40’s power window, power lock, power mirror and cruise control switches are lit from behind, making them plainly visible and easier to operate at night. The GLA’s cruise control switches are unlit, making them difficult to find at night and operate safely.

Heated windshield washer nozzles are optional on the XC40 to prevent washer fluid and nozzles from freezing and help continue to keep the windshield clear in sub-freezing temperatures. The GLA doesn’t offer heated windshield washer nozzles.

To improve rear visibility by keeping the rear window clear, the XC40 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.

Consumer Reports rated the XC40’s headlight performance “Very Good,” a higher rating than the GLA’s headlights, which were rated “Poor.”

In poor weather, headlights can lose their effectiveness as grime builds up on their lenses. This can reduce visibility without the driver realizing. The XC40 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 XC40 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 XC40 has standard cornering lights to illuminate around corners when the turn signals are activated. The GLA doesn’t offer cornering lights. The XC40 also has standard adaptive headlights to illuminate around corners automatically by reading vehicle speed and steering wheel angle.

When the XC40 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.

Both the XC40 and the GLA offer optional heated front seats. The XC40 also offers optional heated rear seats to keep those passengers extremely comfortable in the winter. Heated rear seats aren’t available in the GLA.

On extremely cold winter days, the XC40’s 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.
