Completely redesigned for 2020, the Nissan Sentra understandably returns for 2021 with no major changes—unless you consider the addition of a six-speed manual transmission in SR trim to be big news. Every other model uses a continuously variable transmission. As for the engine, we’re dealing with a 2.0-litre four-cylinder that produces 149 horsepower. The Sentra’s looks are pretty sharp, while protection for all occupants comes from Nissan’s Safety Shield 360.
