The Sentra SE-R and SE-R Spec V are sporty variants with a 2.5-liter four-cylinder. The SE-R is built for mainstream consumers who want a sportier feel; the Spec V is geared toward the enthusiast crowd.

Both SE-Rs are distinguished from regular Sentras by exterior enhancements, including different nose and tail treatments, side sill extensions and a rear spoiler. The SE-R boasts numerous interior upgrades, including an oil pressure gauge, lateral g-force meter and cloth sport seats embroidered with the SE-R designation. The SE-R Spec V adds red seat belts.

The Sentra's MacPherson strut front suspension and, particularly, the semi-independent torsion-beam rear suspension are unlikely to please sport enthusiasts, but performance, not construction, is what matters most. The Spec V has a firmer suspension and larger brakes. Features include:

Standard stability system and traction control 200-hp, 2.5-liter four-cylinder with 180 pounds-feet of torque (Spec V) 177-hp, 2.5-liter four-cylinder with 172 pounds-feet of torque (SE-R) Standard six-speed manual transmission (Spec V) Standard CVT with paddle shifters (SE-R) Premium gas recommended for Spec V Standard 17-inch aluminum-alloy wheels Optional 340-watt Rockford Fosgate stereo Optional moonroof, limited-slip differential, backup camera and navigation system
