Safety

For enhanced safety, the front and rear seat shoulder belts of the Mercedes AMG GLC 63 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 Jeep Grand Cherokee SRT doesn’t offer pretensioners for the rear seat belts.

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

The AMG GLC 63 Coupe offers an optional Surround View System to allow the driver to see objects all around the vehicle on a screen. The Grand Cherokee SRT only offers a rear monitor and front and rear parking sensors that beep or flash a light. That doesn’t help with obstacles to the sides.

The AMG GLC 63 Coupe’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 Grand Cherokee SRT doesn’t offer a driver alert monitor.

Both the AMG GLC 63 Coupe and the Grand Cherokee SRT 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, blind spot warning systems, rearview cameras and available lane departure warning systems.

Warranty

The AMG GLC 63 Coupe comes with a full 4-year/50,000-mile basic warranty, which covers the entire truck and includes 24-hour roadside assistance. The Grand Cherokee SRT’s 3-year/36,000-mile basic warranty expires 1 year and 14,000 miles sooner.

Tires and Wheels

The AMG GLC 63 Coupe’s standard 295/40R20 rear tires provide better handling because they have a lower 40 series profile (height to width ratio) that provides a stiffer sidewall than the Grand Cherokee SRT’s standard 45 series tires. The AMG GLC 63 Coupe’s optional 265/40R21 front and 295/35R21 rear tires have a lower 40 series front and 35 series rear profile than the Grand Cherokee SRT’s 45 series tires.

For better ride, handling and brake cooling the AMG GLC 63 Coupe offers optional 21-inch wheels. The Grand Cherokee SRT’s largest wheels are only 20-inches.

Suspension and Handling

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

The AMG GLC 63 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 Grand Cherokee SRT doesn’t offer drift compensation steering.

The AMG GLC63 S Coupe handles at .96 G’s, while the Grand Cherokee SRT pulls only .88 G’s of cornering force in a Motor Trend skidpad test.

The AMG GLC63 S Coupe executes Motor Trend’s “Figure Eight” maneuver 2.3 seconds quicker than the Grand Cherokee SRT (24.1 seconds @ .85 average G’s vs. 26.4 seconds @ .71 average G’s).

Chassis

The Mercedes AMG GLC 63 Coupe may be more efficient, handle and accelerate better because it weighs about 650 to 700 pounds less than the Jeep Grand Cherokee SRT.

The AMG GLC 63 Coupe is 3 inches shorter than the Grand Cherokee SRT, making the AMG GLC 63 Coupe easier to handle, maneuver and park in tight spaces.

Cargo Capacity

Pressing a switch automatically lowers the AMG GLC 63 Coupe’s rear seats, to make changing between passengers and cargo easier. The Grand Cherokee SRT doesn’t offer automatic folding seats.

To make loading groceries and cargo easier when your hands are full, the AMG GLC 63 Coupe’s available liftgate can be opened and closed just by kicking your foot under the back bumper, leaving your hands completely free. The Grand Cherokee SRT doesn’t offer a hands-free gesture to open its liftgate, 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 Jeep. J.D. Power ranks Mercedes fifth in service department satisfaction. With a 67% lower rating, Jeep is ranked 28th.

Ergonomics

Unlike the driver-only memory system in the Grand Cherokee SRT, the AMG GLC 63 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 63 Coupe offers an optional heads-up display that projects speed and other key instrumentation readouts in front of the driver’s line of sight, allowing drivers to view information without diverting their eyes from the road. The Grand Cherokee SRT doesn’t offer a heads-up display.

The AMG GLC 63 Coupe’s front and rear power windows all open or close fully with one touch of the switches, making it more convenient at drive-up windows and toll booths, or when talking with someone outside the car. The Grand Cherokee SRT’s rear power window switches have to be held the entire time to open or close them fully.

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