Safety

For enhanced safety, the front and rear seat shoulder belts of the Mercedes AMG GLC 63 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 X6 M doesn’t offer pretensioners for the rear seat belts.

For enhanced safety, the front seat shoulder belts of the Mercedes AMG GLC 63 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 X6 M doesn’t offer height-adjustable seat belts.

Both the AMG GLC 63 and the X6 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, available lane departure warning systems and rear parking sensors.

Transmission

A nine-speed automatic is standard on the Mercedes AMG GLC 63, for better acceleration and lower engine speed on the highway. Only an eight-speed automatic is available for the X6 M.

Suspension and Handling

The front and rear suspension of the AMG GLC 63 uses air springs for a smoother, controlled ride than the X6 M, which uses coil springs in front. Air springs maintain proper ride height and ride more smoothly.

The AMG GLC 63’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 X6 M doesn’t offer drift compensation steering.

For better maneuverability, the AMG GLC 63’s turning circle is 2.3 feet tighter than the X6 M’s (39.7 feet vs. 42 feet).

Chassis

The Mercedes AMG GLC 63 may be more efficient, handle and accelerate better because it weighs about 700 pounds less than the BMW X6 M.

The AMG GLC 63 is 9.5 inches shorter than the X6 M, making the AMG GLC 63 easier to handle, maneuver and park in tight spaces.

Passenger Space

The AMG GLC 63 has .5 inches more front legroom, .6 inches more rear headroom and 1.7 inches more rear legroom than the X6 M.

For enhanced passenger comfort on long trips the AMG GLC 63’s rear seats recline. The X6 M’s rear seats don’t recline.

Cargo Capacity

Pressing a switch automatically lowers or raises the AMG GLC 63’s rear seats, to make changing between cargo and passengers easier. The X6 M doesn’t offer automatic folding seats.

Servicing Ease

J.D. Power and Associates surveys of service recipients show that Mercedes service is better than BMW. J.D. Power ranks Mercedes fifth in service department satisfaction. With a 23% lower rating, BMW is ranked 11th.

Ergonomics

The AMG GLC 63 has a standard remote vehicle starting system, so the vehicle can be started from inside the driver's house. This allows the driver to comfortably warm up the engine before going out to the vehicle. The climate system will also automatically heat or cool the interior. The X6 M doesn’t offer a remote starting system.

To improve rear visibility by keeping the rear window clear, the AMG GLC 63 has a standard rear wiper. The X6 M doesn’t offer a rear wiper.

To keep a safe, consistent following distance, the AMG GLC 63 offers an optional Distronic Plus, which alters the speed of the vehicle without driver intervention. This allows the driver to use cruise control more safely without constantly having to disengage it when approaching slower traffic. The X6 M doesn’t offer an adaptive cruise control.

The AMG GLC 63 has a 115-volt a/c outlet, allowing you to recharge a laptop or run small household appliances without special adapters that can break or get misplaced. The X6 M doesn’t offer a house-current electrical outlet.

Model Availability

The Mercedes AMG GLC 63 comes in traditional 4-door sport utility and 4-door coupe bodystyles; the BMW X6 M isn’t available as a conventional sport utility.
