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.

Over 200 people are killed each year when backed over by motor vehicles. The XT5 Premium Luxury/Sport offers optional Reverse Automatic Braking that uses rear sensors to monitor for objects to the rear and automatically applies the brakes to prevent a collision. The GLC doesn’t offer automatic braking for stationary objects directly to the rear.

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.

New test not comparable to pre-2011 test results. More stars = Better. Lower test results = Better.

Warranty

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.

Reliability

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.

A reliable vehicle saves its owner time, money and trouble. Nobody wants to be stranded or have to be without a vehicle while it’s being repaired. Consumer Reports rates the XT5’s reliability 18 points higher than the GLC.

J.D. Power and Associates rated the XT5 third among midsize premium suvs in their 2023 Initial Quality Study. The GLC isn’t in the top three in its category.

J.D. Power and Associates’ 2023 Initial Quality Study of new car owners surveyed provide the statistics that show that Cadillac vehicles are better in initial quality than Mercedes vehicles. J.D. Power ranks Cadillac above average in initial quality. With 31 more problems per 100 vehicles, Mercedes is rated below average.

J.D. Power and Associates’ 2022 survey of the owners of three-year-old vehicles provides the long-term dependability statistics that show that Cadillac vehicles are more reliable than Mercedes vehicles. J.D. Power ranks Cadillac above average in long-term dependability. With 24 more problems per 100 vehicles in the first three years of ownership, Mercedes is rated below average.

From surveys of all its subscribers, Consumer Reports’ January 2023 Auto Issue reports that Cadillac vehicles are more reliable than Mercedes vehicles. Consumer Reports ranks Cadillac 7 places higher in reliability than Mercedes.

Engine

The XT5’s optional 3.6 DOHC V6 produces 55 more horsepower (310 vs. 255) than the GLC’s 2.0 turbo 4-cylinder.

As tested in Motor Trend the Cadillac XT5 V6 is faster than the Mercedes GLC:

	XT5	GLC
Zero to 60 MPH	6.4 sec	6.9 sec
Quarter Mile	15 sec	15.2 sec
Speed in 1/4 Mile	91.4 MPH	89.6 MPH

Fuel Economy and Range

On the EPA test cycle the XT5 2.0 turbo 4-cylinder FWD gets better fuel mileage than the GLC 300 RWD (22 city/29 hwy vs. 22 city/27 hwy).

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.

Brakes and Stopping

The XT5 stops much shorter than the GLC:

	XT5	GLC
60 to 0 MPH	111 feet	126 feet	Motor Trend

Tires and Wheels

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.

Suspension and Handling

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.

For better handling and stability, the track (width between the wheels) on the XT5 is .9 inches wider in the front and 1.1 inches wider in the rear than on the GLC.

The XT5 AWD handles at .82 G’s, while the GLC 300 4MATIC pulls only .80 G’s of cornering force in a Motor Trend skidpad test.

For greater off-road capability the XT5 has a 2.8 inches greater minimum ground clearance than the GLC (7.8 vs. 5 inches), allowing the XT5 to travel over rougher terrain without being stopped or damaged.

Passenger Space

The XT5 has 1.9 inches more front headroom, .4 inches more front legroom, 1 inch more front shoulder room and 1.7 inches more rear legroom than the GLC.

The front step up height for the XT5 is 1.5 inches lower than the GLC (18.5” vs. 20”). The XT5’s rear step up height is 2.5 inches lower than the GLC’s (20” vs. 22.5”).

Cargo Capacity

The XT5 has a much larger cargo volume with its rear seat up than the GLC with its rear seat up (30.2 vs. 19.4 cubic feet). The XT5 has a much larger cargo volume with its rear seat folded than the GLC with its rear seat folded (63 vs. 56.5 cubic feet).

The XT5’s cargo area is larger than the GLC’s in almost every dimension:

	XT5	GLC
Length to seat (2nd/1st)	41.5”/75”	36.6”/61.3”
Max Width	51”	49.4”
Min Width	41.6”	43.3”
Height	30”	31.1”

Towing

A Trailer Sway Control is standard on the XT5, using the StabiliTrak® sensors to detect trailer sway, then uses individual brakes to counteract any swaying and help keep the tow vehicle and trailer steady. A trailer sway program costs extra on the GLC.

Servicing Ease

J.D. Power and Associates surveys of service recipients show that Cadillac service is better than Mercedes. J.D. Power ranks Cadillac second in service department satisfaction. With a 31% lower rating, Mercedes is ranked 18th.

Ergonomics

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.

Economic Advantages

Insurance will cost less for the XT5 owner. The Car Book by Jack Gillis rates the XT5 with a number “8” insurance rate while the GLC is rated higher at a number “10” rate.

According to The Car Book by Jack Gillis, the XT5 is less expensive to operate than the GLC because typical repairs cost much less on the XT5 than the GLC, including $336 less for a water pump, $145 less for front brake pads, $284 less for a starter, $122 less for fuel injection, $163 less for a fuel pump, $319 less for front struts and $429 less for a power steering pump.

Recommendations

Consumer Reports® recommends the Cadillac XT5, based on reliability, safety and performance. The Mercedes GLC isn't recommended.
