The 2007 Sentra is larger than the car it replaces and will fit into the Nissan lineup above the recently introduced subcompact Versa. The Sentra is built on a new and larger platform and boasts 98 cubic feet of passenger space (up from 88 cubic feet). Horsepower figures weren't finalized, but Nissan expects to generate at least 135 ponies and 140 pound-feet of torque from its new 2.0-liter four-cylinder engine. A six-speed manual is the base transmission, and a continuously variable automatic is optional. The redesigned Sentra will go on sale this fall with a base price of about $15,000.
