The 2009 Nissan Altima is part of the sedan's fourth generation and comes in both sedan and coupe body styles. Under the hood, it sports a 2.5-liter four-cylinder engine producing 175 horsepower, or an optional 3.5-liter V6 generating a potent 270 horsepower. Both engines are paired with a continuously variable transmission (CVT). The Altima is front-wheel-drive, with two main trims available: the 2.5 S and 3.5 SE. The 2009 model showcases key safety features such as anti-lock brakes, stability control, front-seat side airbags and full-length side curtain-type airbags. Its tech highlights include an available navigation system, rearview camera, and a premium Bose stereo system. The coupe version, redesigned this year adds a more aggressive look and sporty suspension tuning. The 2009 Altima prioritized comfort, performance, and style, solidifying Nissan's reputation for quality mid-size vehicles.
