The fourth-generation Mazda3 (internal code: BP) marks a significant shift for the brand towards the premium segment. Introduced in 2019, it features a striking evolution of the 'Kodo' design language, a high-quality minimalist interior, and advanced NVH (Noise, Vibration, and Harshness) insulation.

The Mazda3 (BP) is a phenomenal compact car that punches above its weight in terms of design, interior quality, and driving feel. Regarding the 1.8 Skyactiv-D: It is a highly refined and reliable engine, completely avoiding the disastrous mechanical flaws of Mazda's older 2.2D. However, it is strictly suited for drivers who do long highway commutes. If you drive primarily in the city, the DPF will clog, and you will face expensive repairs. For most buyers, the naturally aspirated Skyactiv-G engines remain the safest and most logical choice, offering bulletproof reliability. The Skyactiv-X is a brilliant engineering feat but requires a buyer willing to accept slightly higher maintenance costs (spark plugs). Overall, a highly recommended purchase, provided you buy the right engine for your driving habits.
