No major changes have been made to the little Mazda2 for 2012. Buyers can choose from the GX or GS trims, or go for the Yoroza edition. The only engine offered is a 4-cylinder that produces 100 hp and 98 lbs.-ft. of torque. It’s paired with a 5-speed manual transmission, though a 4-speed automatic is also available on option. The Mazda2 is up against some fierce competition, including the Ford Fiesta, Toyota Yaris, Kia Rio and Hyundai Accent.
