Compare the2023 Mercedes AMG GLC CoupeVS 2023 BMW X3 M

For enhanced safety, the front and rear seat shoulder belts of the Mercedes AMG GLC Coupe have pretensioners to tighten the seatbelts and eliminate dangerous slack in the event of a collision and force limiters to limit the pressure the belts will exert on the passengers. The BMW X3 M doesn’t offer pretensioners for its rear seat belts.

For enhanced safety, the front seat shoulder belts of the Mercedes AMG GLC Coupe are height-adjustable to accommodate a wide variety of driver and passenger heights. A better fit can prevent injuries and the increased comfort also encourages passengers to buckle up. The BMW X3 M doesn’t offer height-adjustable seat belts.

Over 200 people are killed each year when backed over by motor vehicles. The AMG GLC Coupe 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 X3 M doesn’t offer backup collision prevention brakes.

Both the AMG GLC Coupe and X3 M have rear cross-traffic warning, but the AMG GLC Coupe has Active Brake Assist (automatically applies the brakes) to better prevent a collision when backing near traffic. The X3 M’s Cross Traffic Warning doesn’t automatically brake.

Both the AMG GLC Coupe and the X3 M have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, four-wheel antilock brakes, all wheel drive, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, blind spot warning systems, rearview cameras, rear cross-path warning, driver alert monitors and available lane departure warning systems.

There are over 9 percent more Mercedes dealers than there are BMW dealers, which makes it easier should you ever need service under the AMG GLC Coupe’s warranty.

On the EPA test cycle the AMG GLC Coupe gets better mileage than the X3 M:

In its Green Vehicle Guide, the U.S. Environmental Protection Agency (EPA) rates the Mercedes AMG GLC Coupe higher (5 out of 10) than the BMW X3 M (3). This means the AMG GLC Coupe produces up to 16.5 pounds less smog-producing pollutants than the X3 M every 15,000 miles.

A nine-speed automatic is standard on the Mercedes AMG GLC Coupe, for better acceleration and lower engine speed on the highway. Only an eight-speed automatic is available for the X3 M.

The AMG GLC Coupe 63 S offers optional heat-treated ceramic brake rotors, which last ten to twenty times as long as conventional cast iron rotors, don’t rust, don’t fade during repeated high speed braking, and their lighter weight contribute to better braking, handling and acceleration. The X3 M doesn’t offer ceramic brake rotors.

For better traction and acceleration, the AMG GLC Coupe has larger rear tires than the X3 M (285/40R20 vs. 265/45R20).

The AMG GLC 43 Coupe’s standard 285/40R20 rear tires provide better handling because they have a lower 40 series profile (height to width ratio) that provides a stiffer sidewall than the X3 M’s standard 45 series tires. The AMG GLC 43 Coupe’s optional 285/35R21 rear tires have a lower 35 series profile than the X3 M Competition’s 40 series tires.

Changing a flat tire near traffic can be dangerous and inconvenient. The run-flat tires available on the AMG GLC Coupe can be driven up to 50 miles without any air pressure, allowing you to drive to a service station for a repair. The X3 M doesn’t offer run-flat tires.

The front and rear suspension of the AMG GLC Coupe uses air springs for a smoother, controlled ride than the X3 M, which uses coil springs. Air springs maintain proper ride height and ride more smoothly.

The AMG GLC Coupe has a standard automatic front and rear load leveling suspension to keep ride height level with a heavy load or when towing. The AMG GLC Coupe’s height leveling suspension allows the driver to raise ride height for better off-road clearance and then lower it again for easier entering and exiting and better on-road handling. The X3 M doesn’t offer a load leveling suspension.

The AMG GLC Coupe’s drift compensation steering can automatically compensate for road conditions which would cause the vehicle to drift from side to side, helping the driver to keep the vehicle straight more easily. The X3 M doesn’t offer drift compensation steering.

For better handling and stability, the track (width between the wheels) on the AMG GLC Coupe is .6 inches wider in the front and 2.1 inches wider in the rear than on the X3 M.

For better maneuverability, the AMG GLC Coupe’s turning circle is 1.7 feet tighter than the X3 M’s (39.7 feet vs. 41.4 feet).

The Mercedes AMG GLC Coupe may be more efficient, handle and accelerate better because it weighs about 400 pounds less than the BMW X3 M.

The AMG GLC Coupe has .5 inches more front legroom, .8 inches more rear legroom and .5 inches more rear shoulder room than the X3 M.

Optional Trailer Stability Assist on the AMG GLC Coupe 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 X3 M doesn’t offer electronic trailer sway control.

Unlike the driver-only memory system in the X3 M, the AMG GLC Coupe has standard driver and 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 AMG GLC Coupe’s standard easy entry system raises the steering wheel and glides the driver’s seat back, making it easier for the driver to get in and out. The X3 M doesn’t offer an easy entry system.

Heated windshield washer nozzles are standard on the AMG GLC Coupe to prevent washer fluid and nozzles from freezing and help continue to keep the windshield clear in sub-freezing temperatures. The X3 M doesn’t offer heated windshield washer nozzles.

The AMG GLC Coupe has a 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 X3 M doesn’t offer a house-current electrical outlet.
