The Sentra has six trims available: the 2.0, 2.0S, 2.0SL, 2.0SR, SE-R, and the SE-R Spec V. The 2.0-liter four-cylinder engine produces 140-hp and is mated to either a six-speed manual or a continuously variable transmission. The SE-R and SE-R Spec V both have a 2.5-liter four-cylinder engine which produces 177-hp in the SE-R and 200-hp in the Spec V. The SE-R is offered only with a CVT transmission, while the Spec V is paired with a six-speed manual transmission. Safety equipment is extensive on all trims, including dual-stage front airbags, front side airbags, full length curtain airbags, active front seat headrests, and a tire pressure monitoring system. For 2010, the Nissan Sentra receives a number of content and packaging changes. The exterior has been enhanced with new taillights and headlights, and certain models receive new front fascia and grille.
