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 NSX doesn’t offer a remote starting system.

Unlike the driver-only memory seat and mirrors in the NSX, 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. An easy entry system costs extra on the NSX.

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 NSX’s power window switches are unlit, making them difficult to find at night and operate safely.

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 NSX 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 NSX’s visors are fixed into the windshield header.

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 NSX 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 NSX 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 NSX doesn’t offer an adaptive cruise control.
