Nissan packs the 2007 Sentra with decent power that's perfectly acceptable for this type of car and price point. The 140-horsepower 2.0-liter engine is high-revving like most four cylinders, yet it feels refined and delivers what power it has fluidly. The clutch is a little stiff compared to the competition and has a high take up point, though the six-speed manual transmission is precise and offers moderately short throws. At the end of our one-week run, we were recording 24.7 mpg, but that was after a final weekend with our heavy-footed editor. On highway excursions, the Sentra easily climbed near 30 mpg, and would likely have surpassed that figure had those drives been longer.
