2021 Acura NSX: What's New, Specs & Features
Last updated August 4, 2026
The 2021 Acura NSX is essentially a carryover, with one small equipment change: the rear spoiler became standard instead of optional. Its hybrid powertrain, chassis, safety equipment, and cabin technology otherwise stayed the same.
About the 2021 Acura NSX
2nd generation NSX (2017-2022), late-cycle year after the 2019 chassis and equipment update; last standard NSX before the 2022 NSX Type S finale.
Acura positions the NSX as a human-centered supercar: a halo model built to deliver real supercar speed without becoming intimidating or exhausting to drive. Its main selling point is the mix of a twin-turbo hybrid powertrain, torque-vectoring all-wheel drive, and a more usable day-to-day personality than many exotic rivals. Acura’s messaging centers on precision, instant response, and driver confidence, not just raw horsepower numbers.
Acura sold the 2021 NSX in one SH-AWD version, positioning it as a driver-focused hybrid supercar that was still usable on normal roads. Its signature hardware included a 573-hp twin-turbo V6 hybrid system with three electric motors, torque-vectoring all-wheel drive, a 9-speed dual-clutch automatic, and adjustable suspension. A 7-inch touchscreen, navigation, Apple CarPlay, Android Auto, and a nine-speaker ELS Studio audio system handled cabin technology.
