The fourth-generation Mazda3 (internal code: BP) marks a significant shift upmarket for the Japanese manufacturer. Introduced in 2019, it aims to compete not just with mainstream compacts, but with premium offerings from Audi, BMW, and Mercedes-Benz. Available as a 5-door hatchback and a 4-door sedan, it boasts a striking 'Kodo' design, a whisper-quiet cabin, and high-quality interior materials. Mechanically, it controversially replaced the previous generation's multi-link rear suspension with a torsion beam setup, though Mazda's tuning ensures it remains one of the best-handling cars in its class. The powertrain lineup is heavily focused on naturally aspirated petrol engines (Skyactiv-G), the innovative spark-controlled compression ignition engine (Skyactiv-X), and a potent 2.5L Turbo for
The Generation IV Mazda3 is an outstanding choice for buyers who prioritize design, interior quality, and driving dynamics over outright practicality. By sticking to proven naturally aspirated engines and a traditional 6-speed automatic transmission, Mazda has created one of the most reliable compact cars on the market. The 2.0L and 2.5L Skyactiv-G engines are virtually bulletproof, provided the early 2019-2020 recalls have been addressed. The 2.5L Turbo is a fantastic sleeper, though 2021 models require checking for the valve stem seal oil consumption issue. The Skyactiv-X is an engineering marvel but adds complexity for marginal real-world gains over the standard engines. Avoid the diesel unless you exclusively drive on highways. Overall, a highly recommended purchase.
