You wouldn't know the 2006 Sentra is Nissan's compact economy car based on its power, performance, and premium features. Though the base model is relatively bare-boned, the other trims pack in a lot of elements of convenience and comfort at an affordable price. For 2006, Nissan makes minimal changes to the Sentra, as it prepares a major overhaul for 2007.
The 2006 Sentra comes in four trims. The 1.8 and 1.8S feature a 1.8-liter, 4-cylinder engine at 126-hp, available with either a standard 5-speed manual or optional 4-speed automatic. The 1.8S is essentially a Special Edition package that adds most of the cosmetic features of the sportier SE-R trims, such as power front seats, keyless entry, a trip computer, foglights, and rear spoiler. The fun and fast SE-R uses the same engine but tuned to get 165-hp and comes only with the auto tran. The SE-R Spec V hits 175-hp with a 6-speed manual transmission and comes with sport seats and Brembo brakes. The SE-R models are standard with ABS brakes, performance shocks, front side airbags, and either 16 or 17-inch tires (to the 15-inch tires on the 1.8 models).
Drivers love the 2006 Sentra SE-R, because it is fast and quick off the line. The detuned engines are adequate, if not quite as responsive. Owners love the comfortable seats, gas mileage, and overall budget savings. Complaints point out the limited rear legroom and the inadequate cupholders that are located too close to the CD player.
