2018 Acura NSX

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2018 NSX.

Body PASSENGER CARTransmission Automatic (AM-S9)

The 2018 Acura NSX is a passenger car equipped with a 9-speed automated manual transmission and an EPA fuel economy rating of 21/22/21 mpg. Viewed against the model's complaint history spanning 1991 to 2021, the 2018 model year follows a 2017 peak of just six issues—a modest high when the lowest year, 1994, saw only a single complaint. Because the worst year across three decades only reached single digits, the 2018 NSX sits within an exceptionally stable reliability record, offering researchers a low-complaint data point in a historically consistent lineage.
