A redesigned 2007 Sentra bows this fall with fresh styling, more standard power, and added features. The sporty SE-R model is on furlough. A new platform adds 5.9 inches to wheelbase, 2.3 inches to overall length, and 3.2 inches to width vs. the 2000-2006 generation. A 135-hp 2.0-liter 4-cyl engine and 6-speed manual transmission replace a 126-hp 1.8 and 5-speed manual. A continuously variable automatic transmission (CVT) providing near-infinite drive ratios is optional; it replaces a conventional 4-speed automatic. ABS is optional, but front side and curtain side airbags are standard. Also standard are air conditioning and power windows/locks. Sentra's rear seat cushion can be flipped up, allowing the split seatback to fold flat with the floor. Optional are leather upholstery, wireless cell phone link, and keyless entry/starting. Prices won't be announced until just before sales begin, but Nissan says MSRPs will start around $15,000. Keep checking back with us for further news.
