Compared to the previous generation, the 2013 Nissan Altima is 0.8 inches longer and 1.3 inches wider. Viewing the car from the side, it's clear the roofline has been more dramatically raked, with the new car now sporting a more coupe-like profile. But the most obvious changes can be seen in the headlights and taillights, which feature the signature Nissan kink also seen on the Maxima and 370Z. Those headlights are now more arrow-shaped, and use projector headlamps as standard, with HIDs available on 3.5 SL models.

Besides getting new sheet metal, the Altima also receives a completely redone interior with a curvier dash and more modern-looking center stack. The three circular HVAC vents that topped the center stack on the previous model are abandoned in favor of a sleeker pair of rectangular vents, which sit above an available seven-inch central touch screen. Nissan says the front seats are of a NASA-inspired "zero gravity" design, and are intended to relieve pressure points.
