2021 Mazda MAZDA3: What's New, Specs & Features
Last updated August 4, 2026

The biggest change for the 2021 Mazda3 is a new turbocharged 2.5-liter engine paired with standard AWD. This is a trim-expansion year rather than a redesign, with the lineup growing at both the entry and upper ends.
About the 2021 Mazda MAZDA3
4th generation (2019-2024), third model year; not a redesign year, but the year Mazda expanded the range with a new 2.0 entry sedan and the first turbo trims.
Mazda positions the Mazda3 as a premium-leaning compact car and hatchback with elegant styling, a driver-focused feel, and a more upscale cabin than most mainstream rivals. Across Mazda’s own messaging, the themes are sophisticated design and engaging driving dynamics rather than raw value or max space. For most shoppers, the Mazda3’s identity is simple: it offers the practicality of a compact car but feels a step richer inside and more polished to drive than many competitors like the Corolla or Elantra.
The 2021 range stretches from a straightforward 155-hp 2.0-liter sedan to turbocharged sedan and hatchback models with standard AWD. The 2.5 S serves as the middle ground with smartphone integration, while Preferred adds everyday comforts such as heated seats and a power moonroof. At the top, Premium Plus combines turbo power with leather seats, navigation, a 360-degree camera and extra low-speed driver aids.

Frequently asked questions
What is the biggest change to the 2021 Mazda3?
The biggest change is the arrival of a turbocharged 2.5-liter engine with standard AWD. It powers the new 2.5 Turbo and Premium Plus trims and gives the Mazda3 much stronger acceleration than the non-turbo versions.
Is the 2021 Mazda3 a redesigned model?
No, the 2021 Mazda3 is not redesigned. It remains part of the fourth generation introduced for 2019, but its engine and trim range expands substantially for this model year.
What engines does the 2021 Mazda3 have?
The 2021 Mazda3 has three engine choices: a 155-hp 2.0-liter four-cylinder in the entry sedan, a non-turbo 2.5-liter four-cylinder in the middle trims, and a turbocharged 2.5-liter four-cylinder in the Turbo and Premium Plus trims. The turbo models have standard AWD.
How does the 2021 Mazda3 Premium Plus differ from the 2.5 Turbo?
The Premium Plus adds more luxury and driver-assistance equipment to the turbo powertrain and standard AWD. Its notable features include leather seats, navigation, a 360-degree camera, front and rear parking sensors, rear automatic braking and Traffic Jam Assist.
Is the 2021 Mazda3 worth choosing over the 2020 model?
Yes, if you want the turbo engine, the new 2.0-liter entry sedan or the expanded trim equipment. The 2021 is otherwise not a redesign, so shoppers satisfied with the earlier engine range may find the two years broadly similar.
