CVT. Real gas sipper! Super gas saver! Be the talk of the town when you roll down the street in this fuel-efficient 2009 Nissan Altima. New Car Test Drive said it ...offers a sporty alternative to the other midsize sedans and we think it's a good choice... This 2009 Altima 2.5 SL may be an economical 4-cylinder but don't think this is some bare bones base trim. The SL package comes with heated leather seats premium interior finishes built-in HomeLink integration for garage doors and home automation etc adding to an extensive list of features included in the 2.5 S series. J.D. Power and Associates gave the 2009 Altima 4 out of 5 Power Circles for Overall Initial Quality Mechanical.
