After 2002 Altima offers two types of engine: the new 4 cylinder 2.5 L QR model engine which is fairly powerful (175 horsepower) and, I believe, one of the best engine in its class the 3.5L V6 VQ model engine with 240 horsepower. The same V6 model as in in the Nissan Maxima, Pathfinder and Murano. Both engines feature continuously variable valve timing using a silent chain instead of timing belt. Throttle cable is gone - the throttle operates electronically by wire based on gas pedal sensor readings. This design provides smoother transmission shifting and lower emission. The 2007 Nissan Altima 3.5L Sedan, has a Timing Chain, and an Ignition Coil Pack. NO DISTRIBUTOR.
