The redesigned Mazda3 is offered in sedan or hatchback forms. The sole engine is a carryover 2.5-liter four-cylinder engine mated to a six-speed manual or automatic transmission. All-wheel drive is now available. The interior is nicely furnished and features a new infotainment system that drivers interact with by using a screen exclusively through a rotary knob. Handling is still nimble but less sporty than in the previous 3. Mazda has improved the ride; it’s firm, but absorbs impacts well. The cabin is relatively quiet and nicely finished. There is an available Driver Monitoring System that watches the driver's face and sounds an alert to warn of fatigue. For 2021 a new 2.0-liter became the base engine, and a much more powerful 2.5-liter turbo is optional. The latter is coupled to all-wheel-drive. The 2.0-liter engine was dropped in 2023. ACC is standard for 2025.
