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 X5 M doesn’t offer pretensioners for the rear seat belts.

The AMG GLC 63’s pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The X5 M doesn’t offer pre-crash pretensioners.

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 X5 M doesn’t offer height-adjustable seat belts.

Both the AMG GLC 63 and the X5 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, daytime running lights, rearview cameras, available lane departure warning systems and rear parking sensors.

Fuel Economy and Range

On the EPA test cycle the AMG GLC 63 gets better fuel mileage than the X5 M (16 city/22 hwy vs. 14 city/19 hwy).

Environmental Friendliness

In its Green Vehicle Guide, the U.S. Environmental Protection Agency (EPA) rates the Mercedes AMG GLC 63 higher (5 out of 10) than the BMW X5 M (3). This means the AMG GLC 63 produces up to 16.5 pounds less smog-producing pollutants than the X5 M every 15,000 miles.


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 X5 M.

Suspension and Handling

The front and rear suspension of the AMG GLC 63 uses air springs for a smoother, controlled ride than the X5 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 X5 M doesn’t offer drift compensation steering.

For better maneuverability, the AMG GLC 63’s turning circle is 2.3 feet tighter than the X5 M’s (39.7 feet vs. 42 feet).


The Mercedes AMG GLC 63 may be more efficient, handle and accelerate better because it weighs about 800 pounds less than the BMW X5 M.

The AMG GLC 63 is 8.4 inches shorter than the X5 M, making the AMG GLC 63 easier to handle, maneuver and park in tight spaces.

Passenger Space

The AMG GLC 63 has .4 inches more front legroom, .2 inches more rear headroom and .7 inches more rear legroom than the X5 M.

For enhanced passenger comfort on long trips the AMG GLC 63’s rear seats recline. The X5 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 X5 M doesn’t offer automatic folding seats.

The AMG GLC 63’s liftgate lifts up in one piece, completely out of the way of loading and unloading, while sheltering the cargo loading area. The X5 M’s tailgate’s top part raises up, but the bottom part lowers, getting in the way of loading and making an uneven surface for sliding cargo.

To make loading groceries and cargo easier when your hands are full, the AMG GLC 63’s available liftgate can be opened and closed just by kicking your foot under the back bumper, leaving your hands completely free. The X5 M doesn’t offer a hands-free gesture to open its tailgate, forcing you to put cargo down if your hands are full.

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.


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 X5 M doesn’t offer a remote starting system.

To shield the driver and front passenger’s vision over a larger portion of the windshield and side windows, the AMG GLC 63 has standard extendable sun visors. The X5 M doesn’t offer extendable visors.

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 X5 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 X5 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 X5 M isn’t available as a coupe style sport utility.
