The 3 Series coupe, spun off as its own line. The 440i and M440i bring the B58 six.

The BMW 4 Series is the coupe, convertible, and Gran Coupe counterpart to the 3 Series sedan, split into its own line in 2014. It shares engines and platform with the 3 Series but adds sleeker two-door bodywork. The 440i and current M440i use the B58 turbo inline six for strong performance. The current generation (G22) is known for its large vertical kidney grille, a polarizing design choice. Beneath it, the 4 Series remains a capable rear-drive (or xDrive) sport coupe, with the M4 as the high-performance flagship. On WhipJury, 4 Series submissions favor the 435i, 440i, and M440i coupes.

BMW's electric M3 is expected in production next year on a dedicated EV platform, and a combustion M3 is lined up for 2028 using a modified version of today's S58 twin-turbo inline-six with mild-hybrid help. M boss Frank van Meel has hinted the gas car may even keep a manual.

The next-generation BMW 3 Series, an M350 xDrive, has been photographed undisguised in Munich. The clearest change is at the back, with wide taillights that stretch almost to the center of the trunk and a busier, heavily creased bumper borrowed from the electric Neue Klasse i3. Production starts in the second half of this year.

A sleeper is a car with serious performance hiding under a completely unremarkable exterior. The classic formula is an economy car, family sedan, wagon, or even a minivan built to embarrass sports cars while looking like it is on its way to a dentist appointment. The whole point is that nothing warns you.
