The 2017 Nissan Altima is part of the model's fifth generation. This midsize sedan is available in five trims: 2.5, 2.5 S, 2.5 SR, 2.5 SV, 2.5 SL, and 3.5 SL. The numbers designate the engine equipped, with most models using a 2.5L 4-cylinder that delivers 179 hp. The 3.5 SL, however, operates on a 3.5L V6 producing 270 hp. Both engines pair with a continuously variable automatic transmission (CVT). Noteworthy among the standard features are Bluetooth connectivity and push-button start, while higher trims benefit from advanced tech such as a 7-inch touchscreen, navigation, mobile app integration, and advanced safety equipment including forward collision warning and adaptive cruise control.
