The Altima hasn’t changed much this year, though Nissan hasn’t brought back the coupe version. This leaves buyers with the sedan, available in five trim levels. All come with the same four-cylinder engine, except the 3.5 SL which has a 270-hp V6. A CVT equips each of them and transmits power to the front wheels in all cases. The hybrid was also pulled off the shelf for 2015.
