The 2021 Mazda3 is a compact sedan offering a standout combination of sporty handling and premium, almost-luxury details. It comes in six trims: 2.0, 2.5 S, Select, Preferred, Premium, and Turbo. The 2.0 and 2.5 S trims come standard with a 155-hp 2.0-liter and 186-hp 2.5-liter four-cylinder engines respectively, while the top-of-the-line Turbo gets a potent 250-hp 2.5-liter turbo four. The Mazda3 offers both front- and all-wheel drive. Its six-speed automatic transmission offers smooth shifts and quick responses. Inside, it features an 8.8-inch central display, Apple CarPlay, Android Auto and a well-rounded suite of driver aids, such as adaptive cruise control and lane-keeping assist. For the 2021 model year, a new base 2.0 engine option and a Turbo model were added.
