The 2007 Nissan Sentra gets to come out of its shell a bit and experiment. Now that the upcoming Versa will be filling the economy compact role, the Sentra becomes a little bigger and lot more high-end, offering a lot more features, but retaining its budget price, good reliability record, and fuel economy. The 2007 Sentra gets a total makeover this year and borrows most of its exterior lines from the upscale Maxima. Right now only available in base, S, and SL trims (the sportier SE-R should come out late in 2007), a new 2.0-liter, DOHC I4 engine hitting 140-hp sits under the hood. This comes standard with a 6-speed manual or optional CVT continuously variable automatic transmission, for imperceptible gear changes. The CVT is standard in the SL. Stretched in all directions, the 2007 Sentra is longer, taller, and wider, offering more overall interior room for four adults. Power locks, windows, electronic steering, air conditioning, and lots of side airbags are all standard. ABS is standard on all but the base model. A long list of options decks the Sentra out in style, offering leather seats (standard on SL), keyless entry, MP3 player, and Bluetooth capability. A new "floating shifter" juts out from the center panel. The rear seats split-fold 60/40 flat, and unique trunk compartments allow for even more storage. The 2007 Sentra still rates high for gas mileage, overall build quality, and durability. Owners also like the extra room. Some say it could use more power, as the weight of the car has increased, but they love the CVT and say the ride is generally smooth. There is some noise at high speeds, and many owners aren't fond of the chunky exterior style.
