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 720S 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 720S 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 720S doesn’t offer a lane departure warning system.

The Mercedes AMG GT’s optional blind spot warning system uses digital cameras monitored by computer to alert the driver to moving objects in the vehicle’s blind spots where the side view mirrors don’t reveal them and moves the vehicle back into its lane. The 720S doesn’t offer a system to reveal objects in the driver’s blind spots.

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 720S doesn’t offer a driver alert monitor.

The Mercedes AMG GT has standard Mercedes-Benz Emergency Call, which uses a global positioning satellite (GPS) receiver and a cellular system to get turn-by-turn driving directions, remotely unlock your doors if you lock your keys in, help track down your vehicle if it’s stolen or send emergency personnel to the scene if any airbags deploy. The 720S doesn’t offer a GPS response system, only a navigation computer with no live response for emergencies, so if you’re involved in an accident and you’re incapacitated help may not come as quickly.

Both the Mercedes AMG GT and the 720S have standard driver and passenger frontal airbags, driver and front passenger knee airbags, side-impact head airbags, front seatbelt pretensioners, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, daytime running lights and rearview cameras.

The Mercedes AMG GT offers a 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 720S doesn’t offer a remote starting system.

The Mercedes AMG GT’s standard easy entry system raises the steering wheel, making it easier for the driver to get in and out. An easy entry system costs extra on the 720S.

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 720S can’t use the remote to operate the windows.

The Mercedes AMG GT’s power window, power lock, power mirror and cruise control switches are lit from behind, making them plainly visible and easier to operate at night. The 720S’ cruise control switches are unlit, making them difficult to find at night and operate safely.

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 720S doesn’t offer automatic dimming high beams.

To shield the driver and front passenger’s vision over a larger portion of the windshield, the Mercedes AMG GT offers optional extendable sun visors. The 720S doesn’t offer extendable visors.

The Mercedes AMG GT’s optional sun-visors swivel front-to-side to block glare from the side windows. The 720S’ visors are fixed into the windshield header.

The Mercedes AMG GT’s power mirror controls are mounted on the armrest for easy access. The 720S’ power mirror controls are on the dash where they are possibly hidden by the steering wheel and are awkward to manipulate.

The Mercedes AMG GT has standard automatic dimming rear and side view mirrors which automatically darken quickly when headlights shine on them, keeping following vehicles from blinding or distracting the driver. The 720S has an automatic rear view mirror, but its side mirrors don’t dim.

Optional air-conditioned seats in the Mercedes AMG GT keep the driver and front passenger comfortable and take the sting out of hot seats in summer. The 720S doesn’t offer air-conditioned seats.

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 720S doesn’t offer an adaptive cruise control.

To help keep the driver’s hands on the wheel, the Mercedes AMG GT has standard steering wheel controls for the radio. The 720S doesn’t offer steering wheel audio controls.

With standard voice command, the Mercedes AMG GT offers the driver hands free control of the radio, climate controls and the navigation computer by simply speaking. The 720S doesn’t offer a voice control system.
