Introduced in 2019, the third-generation BMW 1 Series F40 marked a profound architectural shift by adopting BMW’s modular FAAR front-wheel-drive platform. While purists lamented the departure of rear-wheel drive, the change yielded 33 mm more rear knee room and a larger 380-litre boot, transforming the 1 Series into a far more practical everyday family car. Maintaining an F40 in top condition requires regular BMW 1 Series maintenance, focusing on modern transverse powertrains and software updates.
The powertrain lineup consists of the modular 1.5-litre three-cylinder B38 (118i), 2.0-litre four-cylinder B48 (128ti, M135i xDrive), and efficient B47 diesels (116d, 118d, 120d). Lower output models utilize a seven-speed dual-clutch Steptronic transmission, while high-torque diesels and the 306 hp M135i xDrive employ an eight-speed Aisin automatic gearbox. Upper hydraulic engine mounts represent a frequent wear item that causes cabin vibration if ignored.
