Detailed item info Model OverviewThe Sentra is offered in six models in all: 2. 0. 2. 0 S. 2. 0 SR and 2. 0 SL versions. all for the economically minded but with equipped with progressively more standard equipment. For those who want a compact sedan with more sporty character. there's also the Sentra SE-R and SE-R Spec V. With any of the 2. 0 models. a 140-horsepower. 2. 0L 4-cylinder engine. paired with either a 6-speed manual gearbox or Xtronic continuously variable automatic transmission comes standard. The SE-R gets an upgrade to a 177-hp. 2. 5L four and the CVT. while the SE-R Spec V comes only with a 200-hp version of the larger engine plus a 6-speed manual gearbox. All Sentra models have a strut-type front suspension and rear torsion beam setup with integral stabilizer bar; altogether it brings decent ride quality with good body control in cornering. Ride quality is quite good thanks to a front subframe and rear isolators. SE-R models get paddle-shifters to help add some driver control to the CVT. as well as an upgraded look and sportier trim throughout. But the Spec V is the true performance package. with its close-ratio 6-speed gearbox. available helical limited-slip differential. stiffer suspension. and 4-wheel disc brakes. Tires on the Spec V are also upgraded to V-rated 17-inchers. and in addition to the suspension upgrades a trunk-mounted V-brace helps make the body more rigid for better cornering control. The Spec V's engine is tuned for high-performance situations. with stouter connecting rods. a different cam profile and a raised 7. 00-rpm redline. The Sentra is a compact car. but there's enough space for four adults (or three across in back when needed) provided you don't have too many long-legged passengers. Leather upholstery is optional on the top 2. 0 SL. while most Sentras get a durable-looking cloth upholstery. Trunk space is surprisingly good for a compact as well. and the 60/40-split folding seats on all the trims allow you to easily expand the space for long items. Even the base Sentra includes power windows and locks and a 4-speaker sound system. The 2. 0 S upgrades to a 6-speaker sound system. iPod connectivity. cruise control. a trip computer and keyless entry. The SR model is the sporty way to go. with 16-inch alloy wheels. fog lamps. a rear spoiler. and sportier exterior trim; and at the top of the line. the 2. 0 SL brings an Intelligent Key entry and start system. Bluetooth hands-free. XM satellite radio. a color screen. and a leather-wrapped steering wheel. Options on the Sentra are grouped into just a few packages. A Leather Package adds leather seats and heated front seats to the SL. while a Special Value Package upgrades to a moonroof. Rockford Fosgate audio system. and navigation system with rear-view monitor. On the sportier-looking SR. you can get much of the SL's equipment through the recently introduced Special Edition package.
