Safety

The Allroad has standard Secondary Collision Brake Assist, which automatically apply the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The GLC 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.

To provide maximum traction and stability on all roads, All-Wheel Drive is standard on the Allroad. But it costs extra on the GLC.

When descending a steep, off-road slope, the Allroad’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 Allroad’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 Allroad and the GLC have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, front and rear 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 lane departure warning systems, blind spot warning systems and around view monitors.

Warranty

The Allroad’s corrosion warranty is 7 years longer than the GLC’s (12 vs. 5 years).

Reliability

The Audi Allroad’s engine uses a cast iron block for durability, while the GLC’s engines use an aluminum block. Aluminum engine blocks are much more prone to warp and crack at high temperatures than cast iron.

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 Allroad’s reliability 26 points higher than the GLC.

J.D. Power and Associates’ 2018 survey of the owners of three-year-old vehicles provides the long-term dependability statistics that show that Audi vehicles are more reliable than Mercedes vehicles. J.D. Power ranks Audi 13th in reliability, above the industry average. With 6 more problems per 100 vehicles, Mercedes is ranked 15th.

From surveys of all its subscribers, Consumer Reports’ December 2018 Auto Issue reports that Audi vehicles are more reliable than Mercedes vehicles. Consumer Reports ranks Audi 10 places higher in reliability than Mercedes.

Engine

The Allroad’s 2.0 turbo 4 cyl. produces 7 more horsepower (248 vs. 241) than the GLC 300’s standard 2.0 turbo 4 cyl.

As tested in Motor Trend the Audi Allroad is faster than the GLC 300 2.0 turbo 4 cyl.:

Fuel Economy and Range

To lower fuel costs and make buying fuel easier, the Audi Allroad uses regular unleaded gasoline (premium recommended for maximum performance). The GLC requires premium, which can cost 20 to 55 cents more per gallon.

Transmission

The Allroad offers a standard sequential manual gearbox (SMG). With no clutch pedal to worry about and a fully automatic mode, an SMG is much more efficient than a conventional automatic but just as easy to drive. The GLC doesn’t offer an SMG or a conventional manual transmission.

The Allroad’s launch control uses engine electronics to hold engine RPM’s precisely in order to provide the most stable and rapid acceleration possible, using all of the available traction. The GLC doesn’t offer launch control.

Brakes and Stopping

The Allroad stops shorter than the GLC:

Tires and Wheels

For better traction, the Allroad has larger tires than the GLC (245/45R18 vs. 235/60R18).

The Allroad’s tires provide better handling because they have a lower 45 series profile (height to width ratio) that provides a stiffer sidewall than the GLC’s standard 60 series tires.

The Allroad 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.

Suspension and Handling

The Allroad Premium Plus handles at .81 G’s, while the GLC 300 4MATIC pulls only .80 G’s of cornering force in a Motor Trend skidpad test.

The Allroad Premium Plus executes Motor Trend’s “Figure-Eight” maneuver 1 seconds quicker than the GLC 300 4MATIC (26.3 seconds @ .69 average G’s vs. 27.3 seconds @ .65 average G’s).

For better maneuverability, the Allroad’s turning circle is .6 feet tighter than the GLC’s (38.1 feet vs. 38.7 feet). The Allroad’s turning circle is 1.6 feet tighter than the AMG GLC 43’s (38.1 feet vs. 39.7 feet).

For greater off-road capability the Allroad has a 1.5 inches greater minimum ground clearance than the GLC 300 (6.5 vs. 5 inches), allowing the Allroad to travel over rougher terrain without being stopped or damaged.

Passenger Space

The Allroad has 1.3 inches more front headroom and .5 inches more front legroom than the GLC.

Cargo Capacity

The Allroad has a much larger cargo volume with its rear seat up than the GLC with its rear seat up (24.2 vs. 19.4 cubic feet). The Allroad has a much larger cargo volume with its rear seat folded than the GLC with its rear seat folded (58.5 vs. 56.5 cubic feet).

A low lift-over cargo design makes loading and unloading the Allroad easier. The Allroad’s cargo lift-over height is 26.1 inches, while the GLC’s liftover is 28.8 inches.

Servicing Ease

J.D. Power and Associates surveys of service recipients show that Audi service is better than Mercedes. J.D. Power ranks Audi third in service department satisfaction. With a 3% lower rating, Mercedes is ranked 6th.

Ergonomics

Heated windshield washer nozzles are standard on the Allroad to prevent washer fluid and nozzles from freezing and help continue to keep the windshield clear in sub-freezing temperatures. Heated windshield washer nozzles cost extra on the GLC.

In poor weather, headlights can lose their effectiveness as grime builds up on their lenses. This can reduce visibility without the driver realizing. The Allroad has standard headlight washers to keep headlight output high. The GLC doesn’t offer headlight washers.

Economic Advantages

Insurance will cost less for the Allroad owner. The Complete Car Cost Guide estimates that insurance for the Allroad will cost $50 to $4725 less than the GLC over a five-year period.

The Allroad will cost the buyer less in the long run because of its superior resale value. The IntelliChoice estimates that the Allroad will retain 50.32% to 50.79% of its original price after five years, while the GLC only retains 46.24% to 49.68%.
