Compare the2023 Cadillac XT4VS 2022 Mercedes GLA

For enhanced safety, the front seat shoulder belts of the Cadillac XT4 are height-adjustable to accommodate a wide variety of driver and passenger heights. A better fit can prevent injuries and the increased comfort also encourages passengers to buckle up. The Mercedes GLA doesn’t offer height-adjustable seat belts.

In the past twenty years hundreds of infants and young children have died after being left in vehicles, usually by accident. When turning the vehicle off, drivers of the XT4 are reminded to check the back seat if they opened the rear door before starting out. The GLA doesn’t offer a back seat reminder.

The Cadillac XT4 has standard driver and front passenger side knee airbags mounted low on the dashboard. These airbags helps prevent the driver and front passenger from sliding under their seatbelts or the main frontal airbags; this keeps them better positioned during a collision for maximum protection. Knee airbags also help keep the legs from striking the dashboard, preventing knee and leg injuries in the case of a serious frontal collision. The GLA doesn’t offer a front passenger side knee airbag.

Over 200 people are killed each year when backed over by motor vehicles. The XT4 Premium/Sport offers optional Reverse Automatic Braking 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.

For better traction, the XT4’s optional tires are larger than the largest tires available on the GLA (245/45R20 vs. 235/55R18).

The XT4 has a standard easy tire fill system. When inflating the tires, the vehicle’s integrated tire pressure sensors keep track of the pressure as the tires fill and tell the driver when the tires are inflated to the proper pressure. The GLA doesn’t offer vehicle monitored tire inflation.

The XT4 offers an optional space-saver spare tire so you can replace a flat tire and drive to have the flat repaired or replaced. A spare tire isn’t available on the GLA; it requires you to depend on its run-flat tires, which limits mileage and speed before they are repaired.

The XT4’s instruments include an oil pressure gauge and a temperature gauge - which could save your engine! Often ‘idiot lights’ don’t warn you until damage has been done. The GLA does not have an oil pressure gauge.

To improve rear visibility by keeping the rear window clear, the XT4 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.
