Safety

The NSX has all-wheel drive to maximize traction under poor conditions, especially in ice and snow. The Mercedes AMG GT doesn’t offer all-wheel drive.

Both the NSX and the Mercedes AMG GT have standard driver and passenger frontal airbags, front side-impact airbags, driver 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 and rearview cameras.

Warranty

Acura’s powertrain warranty covers the NSX 2 years and 20,000 miles longer than Mercedes covers the AMG GT. Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 6 years or 70,000 miles. Coverage on the Mercedes AMG GT ends after only 4 years or 50,000 miles.

Reliability

From surveys of all its subscribers, Consumer Reports’ December 2018 Auto Issue reports that Acura vehicles are more reliable than Mercedes vehicles. Consumer Reports ranks Acura 4 places higher in reliability than Mercedes.

Fuel Economy and Range

On the EPA test cycle the NSX gets better fuel mileage than the AMG GT (21 city/22 hwy vs. 16 city/22 hwy). The NSX gets better fuel mileage than the AMG GT R (21 city/22 hwy vs. 15 city/20 hwy).

Regenerative brakes improve the NSX’s fuel efficiency by converting inertia back into energy instead of wasting it. The Mercedes AMG GT doesn’t offer a regenerative braking system.

The NSX has a standard cap-less fueling system. The fuel filler is automatically opened when the fuel nozzle is inserted and automatically closed when it’s removed. This eliminates the need to unscrew and replace the cap and it reduces fuel evaporation, which causes pollution. The Mercedes AMG GT doesn’t offer a cap-less fueling system.

Transmission and Drivetrain

A nine-speed automatic (SMG) is standard on the Acura NSX, for better acceleration and lower engine speed on the highway. Only a seven-speed automatic is available for the Mercedes AMG GT.

All wheel drive, available in the NSX, provides the best traction for acceleration in wet, dry, and icy conditions. In corners, all wheel drive allows both outside wheels to provide power, balancing the car. This allows for better handling. The Mercedes AMG GT is not available with all wheel drive.

Brakes and Stopping

For better stopping power the NSX’s standard brake rotors are larger than those on the Mercedes AMG GT:

Tires and Wheels

For better traction and acceleration, the NSX has larger rear tires than the Mercedes AMG GT (305/30R20 vs. 295/30R19).

For better ride, handling and brake cooling the NSX has standard 20-inch rear wheels. Smaller 19-inch wheels are standard on the Mercedes AMG GT Coupe.

The NSX has a standard easy tire fill system. When inflating the tires, the vehicle’s integrated tire pressure sensors keep track of the pressure as the tires fill and tell the driver when the tires are inflated to the proper pressure. The Mercedes AMG GT doesn’t offer vehicle monitored tire inflation.

Chassis

The NSX is 3 inches shorter than the Mercedes AMG GT, making the NSX easier to handle, maneuver and park in tight spaces.
