The Mercedes AMG GT’s pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The Shelby GT500 doesn’t offer pre-crash pretensioners.

The Mercedes AMG GT has standard Active Brake Assist, which use forward mounted sensors to warn the driver of a possible collision ahead. If the driver doesn’t react and the system determines a collision is imminent, it automatically applies the brakes at full-force in order to reduce the force of the crash or avoid it altogether. The Shelby GT500 doesn't offer collision warning or crash mitigation brakes.

The Mercedes AMG GT’s optional lane departure warning system alerts a temporarily inattentive driver when the vehicle begins to leave its lane and gently nudges the vehicle back towards its lane. The Shelby GT500 doesn’t offer a lane departure warning system.

The Mercedes AMG GT’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 Shelby GT500 doesn’t offer a driver alert monitor.

Both the Mercedes AMG GT and the Shelby GT500 have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger knee airbags, side-impact head airbags, front seatbelt pretensioners, plastic fuel tanks, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, daytime running lights, rearview cameras and available blind spot warning systems.

The Mercedes AMG GT 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.

For better handling and stability, the average track (width between the wheels) on the Mercedes AMG GT is 3 inches wider in the front and 2.2 inches wider in the rear than the track on the Shelby GT500.

The Mercedes AMG GT’s front to rear weight distribution is more even (47.8% to 52.2%) than the Shelby GT500’s (56.6% to 43.4%). This gives the Mercedes AMG GT more stable handling and braking.

The Mercedes AMG GT R Coupe handles at 1.12 G’s, while the Shelby GT500 pulls only 1.01 G’s of cornering force in a Motor Trend skidpad test.

The Mercedes AMG GT R Coupe executes Motor Trend’s “Figure Eight” maneuver 1.3 seconds quicker than the Shelby GT500 (22.8 seconds @ .96 average G’s vs. 24.1 seconds @ .85 average G’s).

The Mercedes AMG GT may be more efficient, handle and accelerate better because it weighs about 400 to 550 pounds less than the Ford Shelby GT500.

The Mercedes AMG GT is 10.8 inches shorter than the Shelby GT500, making the Mercedes AMG GT easier to handle, maneuver and park in tight spaces.

To almost totally eliminate engine vibration in the passenger area, the Mercedes AMG GT has an electronically controlled liquid-filled main engine mount. A computer-controlled electric current in the liquid changes its viscosity, allowing the mount to dampen the engine completely at all RPMs. The Shelby GT500 uses conventional solid rubber engine mounts.

As tested by Car and Driver, the interior of the Mercedes AMG GT Coupe is quieter than the Shelby GT500:

With its convertible body style, valet key and remote trunk release lockout, the Mercedes AMG GT offers cargo security. The Shelby GT500’s non-lockable folding seat and non-lockable remote release defeat cargo security.

To make loading groceries and cargo easier when your hands are full, the Mercedes AMG GT’s available trunk can be opened just by kicking your foot under the back bumper, leaving your hands completely free. The Shelby GT500 doesn’t offer a hands-free gesture to open its trunk, forcing you to put cargo down if your hands are full.

Unlike the driver-only memory seat and mirrors optional at extra cost in the Shelby GT500, the Mercedes AMG GT 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 Mercedes AMG GT’s standard easy entry system raises the steering wheel, making it easier for the driver to get in and out. The Shelby GT500 doesn’t offer an easy entry system.

If the windows are left open on the Mercedes AMG GT the driver can close them all at the outside door handle or from a distance using the remote. On a hot day the driver can lower the windows from a distance using the keyless remote. The driver of the Shelby GT500 can only close the windows from inside the vehicle, with the ignition on.

The Mercedes AMG GT’s rain-sensitive wipers adjust their speed and turn on and off automatically based on the amount of rainfall on the windshield. This allows the driver to concentrate on driving without constantly adjusting the wipers. The Shelby GT500’s intermittent wipers change speed with vehicle speed, but can’t turn on and off or change speed based on changing rainfall.

While driving with high beams on, sensitive light sensors standard on the Mercedes AMG GT detect other vehicles which could be blinded and automatically switch to low beams. The Shelby GT500 doesn’t offer automatic dimming high beams.

To help drivers avoid possible obstacles, the Mercedes AMG GT has standard cornering lights to illuminate around corners when the turn signals are activated. The Shelby GT500 doesn’t offer cornering lights.

The Mercedes AMG GT’s standard outside mirrors include heating elements to clear off the mirrors for better visibility. Ford charges extra for heated mirrors on the Shelby GT500.

When the Mercedes AMG GT is put in reverse, the passenger rearview mirror tilts from its original position. This gives the driver a better view of the curb during parallel parking maneuvers. Shifting out of reverse puts the mirror into its original position. The Shelby GT500’s mirror doesn’t automatically adjust for backing.

The Mercedes AMG GT’s standard rear and side view mirrors have an automatic dimming feature. These mirrors can be set to automatically darken quickly when headlights shine on them, keeping following vehicles from blinding or distracting the driver. The Shelby GT500 has an automatic rear view mirror, but its side mirrors don’t dim.

To keep a safe, consistent following distance, the Mercedes AMG GT offers an optional Active Distance Assist Distronic, 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 Shelby GT500 doesn’t offer an adaptive cruise control.
