For enhanced safety, the GMC Terrain’s rear seat shoulder belts have child comfort guides to move the belt to properly fit children. A better fit can prevent injuries and the increased comfort also encourages children to buckle up. The Mercedes GLC doesn’t offer comfort guides on its rear 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 Terrain 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.

When descending a steep, off-road slope, the Terrain’s standard Hill Descent Control allows you to creep down safely. The GLC doesn’t offer Hill Descent Control.

To help make backing safer, the Terrain (except SL)’s 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 GLC doesn’t offer a cross-path warning system.

Both the Terrain and the GLC have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front seatbelt pretensioners, 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 and around view monitors.

The National Highway Traffic Safety Administration does 35 MPH front crash tests on new vehicles. In this test, results indicate that the GMC Terrain is safer than the Mercedes GLC:

GMC’s powertrain warranty covers the Terrain 1 year and 10,000 miles longer than Mercedes covers the GLC. Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 5 years or 60,000 miles. Coverage on the GLC ends after only 4 years or 50,000 miles.

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

There are almost 5 times as many GMC dealers as there are Mercedes dealers, which makes it much easier should you ever need service under the Terrain’s warranty.

The Terrain’s optional 2.0 turbo 4-cyl. produces 11 more horsepower (252 vs. 241) than the GLC 300’s standard 2.0 turbo 4-cyl.

As tested in Motor Trend the GMC Terrain 2.0 turbo 4-cyl. is faster than the GLC 300 2.0 turbo 4-cyl.:

To lower fuel costs and make buying fuel easier, the GMC Terrain uses regular unleaded gasoline (premium recommended with the 2.0 turbo 4-cyl. engine for maximum performance). The GLC requires premium, which can cost 20 to 55 cents more per gallon.

The Terrain 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 Terrain 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 GLC doesn’t offer vehicle monitored tire inflation.

The Terrain SLE/SLT/Denali has a standard 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 GLC; it requires you to depend on its run-flat tires, which limits mileage and speed before they are repaired. If a run-flat is damaged beyond repair by a road hazard your vehicle will have to be towed.

For better maneuverability, the Terrain w/17” wheels’ turning circle is 1.3 feet tighter than the GLC’s (37.4 feet vs. 38.7 feet).

For greater off-road capability the Terrain SLE has a 1.9 inches greater minimum ground clearance than the GLC 300 (6.9 vs. 5 inches), allowing the Terrain to travel over rougher terrain without being stopped or damaged. The Terrain SLT/Denali’s minimum ground clearance is 1.2 inches higher than on the AMG GLC 43 (7.9 vs. 6.7 inches).

The GMC Terrain may be more efficient, handle and accelerate better because it weighs about 350 to 450 pounds less than the Mercedes GLC.

The Terrain uses computer-generated active noise cancellation to help remove annoying noise and vibration from the passenger compartment, especially at low frequencies. The GLC doesn’t offer active noise cancellation.

The Terrain has a much larger cargo volume with its rear seat up than the GLC with its rear seat up (29.6 vs. 19.4 cubic feet). The Terrain has a much larger cargo volume with its rear seat folded than the GLC with its rear seat folded (63.3 vs. 56.5 cubic feet).

The Terrain’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 Terrain 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.

Insurance will cost less for the Terrain owner. The Complete Car Cost Guide estimates that insurance for the Terrain will cost $2180 to $7110 less than the GLC over a five-year period.

According to The Car Book by Jack Gillis, the Terrain is less expensive to operate than the GLC because typical repairs cost much less on the Terrain than the GLC, including $381 less for a water pump, $28 less for front brake pads, $237 less for a starter, $86 less for fuel injection, $4323 less for front struts and $479 less for a power steering pump.

IntelliChoice estimates that five-year ownership costs (depreciation, financing, insurance, fuel, fees, repairs and maintenance) for the GMC Terrain will be $14943 to $22375 less than for the Mercedes GLC.
