The fourth-generation Mazda3 (internal code BP) marks an assertive move upmarket for the Hiroshima-based manufacturer. Launched in 2019, it stands out with its very pure 'Kodo' design, an interior finish worthy of premium segments, and drastically improved sound insulation compared to the previous generation. Technically, it abandons the multi-link rear suspension for a torsion beam, a controversial but masterfully developed choice that preserves the brand's excellent dynamism. This generation also introduces the revolutionary Skyactiv-X engine (spark-controlled compression ignition) and generalizes mild hybridization (MHEV) across its gasoline engines in Europe. A slight technical revision (e-Skyactiv X update) occurred in 2021, followed by a technological update (infotainment) in 2024. O
The fourth-generation Mazda3 is an extremely relevant used (or new) choice for anyone looking for a reliable, elegant, and rewarding compact car to drive. The classic gasoline engines (Skyactiv-G 122/150 hp or 2.5L) are models of robustness and represent the safest choice. The Skyactiv-X engine is an engineering feat offering an excellent performance/consumption compromise, but it requires meticulous follow-up within the official network. Avoid 2019 models if you fear minor early defects (electronics, parasitic noises) and prioritize a model from 2021 onwards. The diesel should be avoided unless for exclusively highway use.
