2021 Mazda CX-3: What's New, Specs & Features
Last updated August 4, 2026
The 2021 Mazda CX-3 is a light update, led by night pedestrian detection for its standard low-speed automatic emergency braking system. An improved automatic on/off function for the LED headlights is the only other notable change; the trim lineup and powertrain carry over from 2020.
About the 2021 Mazda CX-3
1st generation CX-3 (2016-2021 US), after the 2019 update, final US model year
Mazda positions the CX-3 as a stylish, city-sized crossover for drivers who want a more upscale feel than many small SUVs. Mazda’s own messaging emphasizes contemporary design, engaging driving dynamics, and premium features made standard, so the CX-3 works as an entry point to the brand rather than a stripped-down basic model. Its main draw is maneuverability, standard safety tech, and a cabin and feature set that feel richer than many subcompact rivals.
The 2021 CX-3 is a city-focused small crossover sold in one well-equipped Sport trim, with front-wheel-drive and all-wheel-drive versions. Its 148-hp 2.0-liter engine and six-speed automatic are joined by a 7-inch touchscreen with Apple CarPlay and Android Auto, a head-up display, automatic climate control, and a broad set of driver-assistance features.
