Nissan Altima Overview

The Altima comes in five trim levels: The 2.5, 2.5 S and 2.5 SL are equipped with a 2.5-liter four-cylinder engine, while the 3.5 SE and 3.5 SL feature the powerful 3.5-liter V6. Four, five, and six speed automatic and manual transmissions are available depending on the trim. Safety features include dual-stage frontal airbags. Optional side-impact airbags and roof-mounted curtain airbags are available.

For 2006, Nissan has added four new option packages, and the optional satellite radio receiver is now factory-installed. Models with the V6 and automatic transmission can be ordered with traction control and the side-impact and curtain airbag.
