The 2010 Nissan Altima is a mid-size sedan from its fourth generation, also offered as a coupe variant. It features a 175-hp 2.5-liter four-cylinder engine as standard, with a robust 270-hp 3.5-liter V6 option for those seeking extra power. All engines are mated to a continuously variable transmission (CVT), driving the front wheels. There are three trims available - 2.5 S, 3.5 SR and Hybrid. The Altima offers a decent list of standard features, including keyless entry/ignition, a power-adjustable driver's seat, and cruise control. Unique to this model year is the revised trim level structure, with the sporty 3.5 SE replaced by the luxury-oriented 3.5 SR. The Altima Hybrid, featuring a 2.5-liter four-cylinder engine paired to an electric motor, provides a combined 198 horsepower and noteworthy fuel economy. It also includes a rearview camera and dual-zone automatic climate control. The 2010 Altima incorporates safety features including anti-lock brakes, stability and traction control, front-seat side airbags and full-length curtain-type airbags. Nissan's reputation for high-quality touchpoints is evident in Altima's comfortable and user-friendly interior, featuring a well-integrated navigation system with real-time traffic and digital music storage.
