Curvy, dramatic styling mimics bigger brother Maxima and gives the Altima an upscale vibe. Engine choices are either a 182-hp 2.5-liter four or a 270-hp 3.5-liter V-6, both with a CVT. The SR infuses a little fun by adding stiffer suspension tuning, paddle shifters, and unique wheels. Forward emergency braking with adaptive cruise control creates a robust active-safety bundle. Overall, the Altima is a capable sedan with a decent options list and a roomy, comfortable cabin. "CarandDriver.com"
