Compare the2024 Cadillac XT5VS 2023 Mercedes GLC

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 XT5 are reminded to check the back seat if they opened the rear door before starting out. The GLC doesn’t offer a back seat reminder.

A passive infrared night vision system optional on the XT5 Premium Luxury/Sport helps the driver to more easily detect people, animals or other objects in front of the vehicle at night. Using an infrared camera to detect heat, the system then displays the image on a monitor in the dashboard. The GLC doesn’t offer a night vision system.

The XT5’s standard lane departure warning system alerts a temporarily inattentive driver when the vehicle begins to leave its lane and gently nudges the vehicle back towards its lane. A lane departure warning system costs extra on the GLC.

Both the XT5 and the GLC have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, front seatbelt pretensioners, 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, available all wheel drive, blind spot warning systems, around view monitors and rear cross-path warning.

For its top level performance in all IIHS frontal, side, rear impact and roof-crush tests, and its standard front crash prevention system, the Insurance Institute for Highway Safety grants the XT5 the rating of “Top Safety Pick” for 2017, a rating granted to only 231 vehicles tested by the IIHS. The GLC has not been tested, yet.

Cadillac’s powertrain warranty covers the XT5 2 years and 20,000 miles longer than Mercedes covers the GLC. Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 6 years or 70,000 miles. Coverage on the GLC ends after only 4 years or 50,000 miles.

The XT5’s corrosion warranty is 1 year longer than the GLC’s (6 vs. 5 years).

There are over 46 percent more Cadillac dealers than there are Mercedes dealers, which makes it easier should you ever need service under the XT5’s warranty.

To reliably power the ignition and other systems and to recharge the battery, the XT5 has a standard 170-amp alternator (155-amp - XT5 V6 without Towing Package). The GLC’s 150-amp alternator isn’t as powerful.

An engine control system that can shut down some of the engine’s cylinders helps improve the XT5’s fuel efficiency. The GLC doesn’t offer a system that can shut down part of the engine.

To lower fuel costs and make buying fuel easier, the Cadillac XT5 uses regular unleaded gasoline (premium recommended with the 2.0 turbo 4-cylinder engine for maximum performance). The GLC requires premium, which can cost on average about 82.8 cents more per gallon.

The XT5 FWD’s standard fuel tank has 2 gallons more fuel capacity than the GLC (19.4 vs. 17.4 gallons), for longer range between fill-ups. The XT5 AWD’s standard fuel tank has 4.3 gallons more fuel capacity than the GLC (21.7 vs. 17.4 gallons).

The XT5 has a standard cap-less fueling system. The fuel filler is automatically opened when the fuel nozzle is inserted and automatically closed when it’s removed. This eliminates the need to unscrew and replace the cap and it reduces fuel evaporation, which causes pollution. The GLC doesn’t offer a cap-less fueling system.

The Cadillac XT5’s wheels have 6 lugs for longer wheel bearing life, less chance of rotor warping and greater strength. The Mercedes GLC only has 5 wheel lugs per wheel.

The XT5 offers an available 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 GLC’s suspension doesn’t offer adjustable shock absorbers.

The Cadillac XT5 may be more efficient, handle and accelerate better because it weighs up to about 250 pounds less than the Mercedes GLC.

The front grille of the XT5 2.0 Turbo uses electronically controlled shutters to close off airflow and reduce drag when less engine cooling is needed. This helps improve highway fuel economy. The GLC doesn’t offer active grille shutters.

The XT5 has a standard remote vehicle starting system, so the vehicle can be started from inside the driver's house. This allows the driver to comfortably warm up the engine before going out to the vehicle. The climate system will also automatically heat or cool the interior. The GLC doesn’t offer a remote starting system.

The XT5’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 GLC does not have an oil pressure gauge.

To improve rear visibility by keeping the rear window clear, the XT5 has a standard rear fixed intermittent wiper with a full on position. The rear wiper standard on the GLC only has an intermittent setting, so in a hard rain visibility isn’t as good.
