EPA estimates come from standardized lab tests so cars can be compared fairly; real-world mileage depends on speed, weather, load, tires and driving style.
2021 Acura NSX crash-test ratings
NHTSA 5-Star Safety Ratings for the tested versions. More stars mean a lower chance of serious injury in that type of crash. Rollover risk is NHTSA's estimated chance of rolling over in a single-vehicle crash.
| Tested vehicle | Overall | Frontal | Side | Rollover | Rollover risk | Forward collision warning |
|---|---|---|---|---|---|---|
| 2021 Acura NSX 2 DR AWD | Not rated | Not rated | Not rated | Not rated | — | No |
Source: NHTSA 5-Star Safety Ratings (New Car Assessment Program), checked Oct 26, 2026.
Star ratings compare vehicles of similar size and weight; a frontal rating for a large pickup is not directly comparable with one for a small car.
