Mazda3 is part of a long line of groundbreaking Mazda vehicles that have helped make it the best-selling Mazda in the world. The 2019 Mazda3 sets a new milestone as the first production model to lead Mazda into a bold new era. 

All 2019 Mazda3s come equipped with a SKYACTIV-G 2.5-liter engine that is rated to deliver 186 horsepower at 6,000 rpm and 186 lb-ft of torque at 4,000 rpm. 

While front-wheel drive is standard, Mazda’s predictive i-ACTIV all-wheel drive is available on the Mazda3 hatchback and Mazda3 sedan option packages. To build upon the fuel efficiency Mazda’s SKYACTIV engines are known for, cylinder-deactivation technology is standard on all Mazda3 hatchbacks, Mazda3 Premium package sedans and Mazda3 sedans equipped with i-ACTIV all-wheel drive. 

Along with G-Vectoring Control Plus vehicle dynamic enhancements standard on all 2019 Mazda3 models, various improvements, such as redesigned seats, retuned body structure and an all-new suspension, absorb road vibrations to help provide a smoother and more enjoyable driving experience.
