Drivers who prefer a coupe to a sedan can always turn to the BMW 4 Series, which shares most of the same features as the 3 Series but comes with two doors instead of four. No significant changes are planned for the 2026 lineup. Engine output still ranges from 255 to 523 horsepower, with the formidable M4 Competition serving as the top-of-the-line model. In addition to the coupe, the 4 Series remains available as a convertible.
