Nissan's compact car, the Sentra, needed to get back in shape to remain competitive in a segment where every manufacturer strives to offer the best car of the group. The 2017 Sentra offers an updated, sportier ride. In addition to the 130-horsepower, 1.8-litre four-cylinder engine, there's now a 188-horsepower, 1.6-litre turbo four available in the SR Turbo and NISMO variants.
