The second-generation Mazda3 (BL code), marketed from 2009, succeeds the very popular BK generation. Based on an evolution of the C1 platform (shared with the Ford Focus II and Volvo C30), it stands out for its particularly dynamic road handling, precise steering, and excellent manual gearbox control. Aesthetically, it adopts the "Nagare" design characterized by its famous smiling grille. A facelift occurred in late 2011, bringing subtle aesthetic touches, improved sound insulation, optimized suspension settings, and the introduction of the first Skyactiv-G engines in certain markets (North America, Japan). Overall, it is an extremely reliable compact car with gasoline engines, but it suffered from the whims of its diesel engines (shared with PSA/Ford or developed in-house).
The Mazda3 (BL) is a compact car with two faces. If you opt for a gasoline engine (1.6, 2.0, 2.5 or Skyactiv), you are buying one of the most reliable and enjoyable cars to drive of its generation. Maintenance is limited to classic consumables. However, diesel versions require extreme caution: the 1.6 109 hp is to be absolutely avoided due to its design flaws (turbo/injectors), while the 2.2 MZR-CD requires rigorous monitoring of its timing chain and DPF. The 1.6 115 hp (post-2010) remains the only recommendable diesel. Prioritize a facelifted gasoline model (post-2011) to benefit from better sound insulation.
