Both the Altima sedan and coupe earn "good" ratings from the Insurance Institute for Highway Safety (IIHS) in front- and side-impact crash tests, but they rate only "acceptable" for rear impacts and for roof strength.
In the newly revised testing performed by the National Highway Traffic Safety Administration (NHTSA), introduced for 2011, the Altima sedan earns four stars overall, including four stars in frontal impact and five stars for side protection. The coupe has not yet been rated.
Front, side, and curtain airbags are all standard across the Altima lineup. So are electronic stability control and anti-lock brakes, along with active head restraints that should help reduce the chance of whiplash. A rearview camera is available, but its vision of the world behind you is displayed on a smaller 4.3-inch LCD screen, versus the larger screens you'd find on vehicles like the Fusion, Optima and Sonata. Blind-spot warning systems are not available on the Altima.
