Safety

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 Cayenne doesn’t offer pre-crash pretensioners.

The AMG GLC 63’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 Cayenne doesn’t offer a driver alert monitor.

Both the AMG GLC 63 and the Cayenne have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, height adjustable front shoulder belts, four-wheel antilock brakes, all wheel drive, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, rearview cameras, available lane departure warning systems and rear parking sensors.

Warranty

There are over 2 times as many Mercedes dealers as there are Porsche dealers, which makes it much easier should you ever need service under the AMG GLC 63’s warranty.

Engine

The AMG GLC 63’s 4.0 turbo V8 produces 134 more horsepower (469 vs. 335) and 147 lbs.-ft. more torque (479 vs. 332) than the Cayenne’s standard 3.0 turbo V6. The AMG GLC 63’s 4.0 turbo V8 produces 35 more horsepower (469 vs. 434) and 73 lbs.-ft. more torque (479 vs. 406) than the Cayenne S’ standard 2.9 turbo V6. The AMG GLC 63’s 4.0 turbo V8 produces 14 more horsepower (469 vs. 455) than the Cayenne E-Hybrid’s standard 3.0 turbo V6 hybrid.

Fuel Economy and Range

On the EPA test cycle the AMG GLC 63 gets better fuel mileage than the X6 Cayenne Turbo (16 city/22 hwy vs. 15 city/19 hwy).

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 Cayenne.

15.4 inches

13.8 inches

Rear Rotors

Tires and Wheels

For better traction, the AMG GLC 63 has larger tires than the Cayenne (F:265/45R20 & R:295/40R20 vs. F:255/55R19 & R:275/50R19).

The AMG GLC 63’s standard 265/45R20 front and 295/40R20 rear tires provide better handling because they have a lower 45 series front and 40 series rear profile (height to width ratio) that provides a stiffer sidewall than the Cayenne’s standard 55 series front and 50 series rear tires.

For better ride, handling and brake cooling the AMG GLC 63 has standard 20-inch wheels. Smaller 19-inch wheels are standard on the Cayenne.

Suspension and Handling

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

Chassis

The AMG GLC 63 is 9.4 inches shorter than the Cayenne, making the AMG GLC 63 easier to handle, maneuver and park in tight spaces.

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 Cayenne doesn’t offer automatic folding seats.

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 Cayenne doesn’t offer a remote starting system.

The AMG GLC 63’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. An easy entry system costs extra on the Cayenne.

If the windows are left open on the AMG GLC 63 the driver can close them all at the outside door handle or from a distance using the remote (remote must be aimed at door sensor). On a hot day the driver can lower the windows from a distance using the keyless remote. The driver of the Cayenne can only operate the windows from inside the vehicle, with the ignition on.

Heated windshield washer nozzles are standard on the AMG GLC 63 to prevent washer fluid and nozzles from freezing and help continue to keep the windshield clear in sub-freezing temperatures. The Cayenne doesn’t offer heated windshield washer nozzles.

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 Cayenne doesn’t offer extendable visors.

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 Cayenne doesn’t offer a house-current electrical outlet.
