Representing the sporting side of the Sentra family, the hot SE-R and hotter SE-R Spec V each boast bigger, more powerful engines, tauter suspensions and lots more attitude than their "normal" Sentra kin. Sharing basic "C" platform front-drive architecture with the core Sentra models, these scintillating sedans each skew towards a slightly different kind of enthusiast. Buyers who demand the convenience of an automatic will find it in the SE-R's Xtronic Continuously Variable Transmission (CVT) with sport mode, while the Spec V offers its extra adrenaline rush only with a six-speed manual gearbox. Either of these rakish road warriors warrants a comparison drive if you're considering the Honda Civic Si or even the pricier Volkswagen Jetta GLI sedan.
