The seventh generation of the Nissan Sentra is a fairly large car, rated by the EPA as a midsize, yet still has a compact-class price. Even in this top-trim SL version, the base price is still less than 20 grand.
Nissan relies on variable valve timing to make this 1.8-liter engine efficient, but only manages to get 130 horsepower out of it. EPA fuel economy estimates sound promising at 30 mpg city and 39 mpg highway.
A badge on the rear of the Sentra reads Pure Drive, mimicking the badges on other cars denoting hybrid systems or other efficiency technology. However, the Sentra's engine is not particularly advanced when compared with others.
