The BMW 3-Series F30/F31/F34/F35, launched in 2012 and produced until 2019, represented the sixth generation of the iconic 3-Series model line. This iteration brought a suite of significant updates, further solidifying its reputation for driving dynamics, luxury, and technological advancements. The F30 chassis designated the sedan, F31 the touring wagon, F34 the Gran Turismo, and F35 the long-wheelbase version of the F30 sedan primarily marketed in China.

Under the hood, the F30/F31/F34/F35 offered a diverse range of powerful and fuel-efficient engine options, encompassing both gasoline and diesel powerplants, ranging from the entry-level 316i to the high-performance M3. The engines were paired with either a six-speed manual transmission or an eight-speed automatic gearbox. A key highlight was the introduction of the first ever diesel-electric hybrid powertrain in a 3-Series model, with the 320d EfficientDynamics Edition. On the exterior, the F30/F31/F34/F35 adopted a more aggressive and sporty design language, characterized by sharp lines, a larger kidney grille, and sculpted bodywork. The interiors were revamped with premium materials, enhanced ergonomics, and the introduction of the iDrive infotainment system, offering navigation, entertainment, and vehicle settings. The F30/F31/F34/F35 also boasted advanced safety features such as lane departure warning, blind spot monitoring, and adaptive cruise control.
