The GLC has standard NECK-PRO front head restraints, which use a specially designed headrest to protect the driver and front passenger from whiplash. During a rear-end collision, the NECK-PRO front head restraints system moves the headrests forward to prevent neck and spine injuries. The Q3 doesn’t offer a whiplash protection system.

Over 200 people are killed each year when backed over by motor vehicles. The GLC has a standard Maneuvering Brake Function that uses rear sensors to monitor for objects to the rear and automatically applies the brakes to prevent a collision. The Q3 doesn’t offer automatic braking for stationary objects directly to the rear.

The GLC’s driver alert monitor detects an inattentive driver then sounds a warning and suggests a break. According to the NHTSA, drivers who fall asleep cause about 100,000 crashes and 1500 deaths a year. The Q3 doesn’t offer a driver alert monitor.

Both the GLC and the Q3 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, blind spot warning systems, rearview cameras, rear cross-path warning, available all wheel drive, lane departure warning systems and around view monitors.

Warranty

There are over 25 percent more Mercedes dealers than there are Audi dealers, which makes it easier should you ever need service under the GLC’s warranty.

Reliability

To reliably power the ignition and other systems and to recharge the battery, the GLC has a standard 150-amp alternator. The Q3’s 140-amp alternator isn’t as powerful.

J.D. Power and Associates’ 2022 Initial Quality Study of new car owners surveyed provide the statistics that show that Mercedes vehicles are better in initial quality than Audi vehicles. With 50 fewer problems per 100 vehicles, JD Power ranks Mercedes higher than Audi.

J.D. Power and Associates’ 2022 survey of the owners of three-year-old vehicles provides the long-term dependability statistics that show that Mercedes vehicles are more reliable than Audi With 37 fewer problems per 100 vehicles in the first three years of ownership, J.D. Power ranks Mercedes higher than Audi.

Engine

The GLC’s 2.0 turbo 4-cylinder hybrid produces 27 more horsepower (255 vs. 228) and 37 lbs.-ft. more torque (295 vs. 258) than the Q3’s 2.0 turbo 4-cylinder.

As tested in Car and Driver the Mercedes GLC is faster than the Audi Q3:

	GLC	Q3
Zero to 60 MPH	5.7 sec	7.4 sec
Zero to 100 MPH	16.2 sec	19.3 sec
5 to 60 MPH Rolling Start	6.6 sec	8.3 sec
Quarter Mile	14.4 sec	15.7 sec
Speed in 1/4 Mile	95 MPH	91 MPH

Fuel Economy and Range

On the EPA test cycle the GLC gets better mileage than the Q3:

			MPG
GLC
	RWD	2.0 turbo 4-cyl. Hybrid	25 city/32 hwy
	AWD	2.0 turbo 4-cyl. Hybrid	23 city/31 hwy
Q3
	AWD	2.0 turbo 4-cyl.	21 city/28 hwy

Regenerative brakes improve the GLC’s fuel efficiency by converting inertia back into energy instead of wasting it. The Q3 doesn’t offer a regenerative braking system.

The GLC has 1.5 gallons more fuel capacity than the Q3 (17.4 vs. 15.9 gallons), for longer range between fill-ups.

Transmission

A nine-speed automatic is standard on the Mercedes GLC, for better acceleration and lower engine speed on the highway. Only an eight-speed automatic is available for the Q3.

Brakes and Stopping

For better stopping power the GLC’s brake rotors are larger than those on the Q3:

	GLC	GLC	Q3
Front Rotors	13.5 inches	14.6 inches	13.4 inches
Rear Rotors	12.6 inches	12.6 inches	11.8 inches
Opt Rear Rotors			12.2 inches

Suspension and Handling

For a smoother ride and more stable handling, the GLC’s wheelbase is 7.6 inches longer than on the Q3 (113.1 inches vs. 105.5 inches).

For better handling and stability, the track (width between the wheels) on the GLC is 1.7 inches wider in the front and 2.7 inches wider in the rear than on the Q3.

Passenger Space

The GLC has 1.7 inches more front headroom, .7 inches more front legroom, .6 inches more front shoulder room, 2.1 inches more rear headroom, 1.3 inches more rear legroom and 1.5 inches more rear shoulder room than the Q3.

Cargo Capacity

The GLC has a larger cargo volume with its rear seat folded than the Q3 with its rear seat folded (59.3 vs. 48 cubic feet).

A control in the cargo area automatically lowers the GLC’s rear seats, to make changing between passengers and cargo easier. The Q3 doesn’t offer automatic folding seats.

Towing

The GLC’s standard towing capacity is much higher than the Q3’s (5291 vs. 1500 pounds).

Standard Trailer Stability Assist on the GLC uses the Electronic Stability Program sensors to detect trailer sway, then uses individual brakes to counteract any swaying and help keep the tow vehicle and trailer steady. The Q3 doesn’t offer electronic trailer sway control.

Servicing Ease

The engine in the GLC is mounted longitudinally (North-South), instead of sideways, as in the Q3. This makes it easier to service and maintain, because the accessory belts are in front.

Ergonomics

Unlike the driver-only memory seat and mirrors optional at extra cost in the Q3, the GLC offers an optional passenger memory, so that when drivers switch, the memory setting adjusts the driver’s seat, steering wheel position and outside mirror angle and the front passenger seat also adjusts to the new passenger’s preset preferences.

The GLC’s standard easy entry and exit feature raises the steering wheel and glides the driver’s seat back, making it easier for the driver to get in and out. The Q3 doesn’t offer an easy entry system.

The GLC offers an optional heads-up display that projects speed and navigation instruction readouts in front of the driver’s line of sight, allowing drivers to view information without diverting their eyes from the road. The Q3 doesn’t offer a heads-up display.

The GLC’s power window, power lock, power mirror and cruise control switches are lit from behind, making them plainly visible and easier to operate at night. The Q3’s cruise control switches are unlit, making them difficult to find at night and operate safely.

The Q3 Premium Plus’ cornering lamps activate a lamp on the front corner when the turn signal is activated. The GLC’s optional adaptive cornering lights turn the actual headlight unit up to several degrees, depending on steering wheel angle and vehicle speed. This lights a significant distance into corners at any speed.

Manual rear side window sunshades are available in the GLC to help block heat and glare for the rear passengers. The Q3 doesn’t offer rear side window sunshades.

When the GLC is put in reverse, the passenger rearview mirror tilts from its original position. This gives the driver a better view of the curb during parallel parking maneuvers. Shifting out of reverse puts the mirror into its original position. The Q3’s mirror doesn’t automatically adjust for backing.

Both the GLC and the Q3 have standard heated front seats. The GLC also offers optional heated rear seats to keep those passengers extremely comfortable in the winter. Heated rear seats aren’t available in the Q3.

Optional air-conditioned seats in the GLC keep the driver and front passenger comfortable and take the sting out of hot seats in Summer. The Q3 doesn’t offer air-conditioned seats.

On extremely cold winter days, the GLC’s optional heated steering wheel provides comfort, allowing the driver to steer safely and comfortably before the vehicle heater warms up. The Q3 doesn’t offer a heated steering wheel.

To quickly and conveniently keep personal devices charged without cables tangling and wearing out, the Mercedes GLC has a standard wireless phone charging system (Qi) in the center console. Only the Q3 Premium Plus offers wireless charging.

The GLC offers an optional 115-volt a/c outlet on the center console, allowing you to recharge a laptop or run small household appliances without special adapters that can break or get misplaced. The Q3 doesn’t offer a house-current electrical outlet.

The GLC’s Active Parking Assist can parallel park or back into a parking spot by itself, starting and stopping automatically, with the driver only responsible for switching from reverse to drive. The Q3 doesn’t offer an automated parking system.

Model Availability

The GLC is available in both rear-wheel drive and four-wheel drive configurations. The Q3 doesn’t offer a two-wheel drive configuration.

Recommendations

Motor Trend selected the GLC as their 2017 Sport Utility of the Year. The Q3 has never been chosen.

The Mercedes GLC outsold the Audi Q3 by almost three to one during 2022.
