F23 · 228i Conv SULEV

What the F23 Chassis Is

The BMW F23 is the convertible variant of BMW's first-generation 2 Series, produced from 2015 through 2021. It shares its underpinnings with the F22 coupe but swaps the fixed roof for a fully automatic soft top, preserving the classic cloth-roof feel that many enthusiasts prefer over a folding hardtop. Compact, rear-drive by default, and available with xDrive all-wheel drive, the F23 slots in as an affordable, tossable open-air BMW that draws directly on the brand's small-coupe heritage.

Models & Body Styles

The U.S. F23 range spanned twelve variants, all convertibles, including SULEV emissions versions sold in certain states:

• 228i Convertible and 228i xDrive Convertible (plus SULEV variants)
• 230i Convertible and 230i xDrive Convertible (plus SULEV variants)
• M235i Convertible and M235i xDrive Convertible
• M240i Convertible and M240i xDrive Convertible

The 228i/230i cars are the volume sellers, while the M235i and M240i are the performance flagships—closely related to, but distinct from, the full M2 (which was never offered as a convertible).

Engines & Drivetrains

The F23 launched with the 228i powered by BMW's 2.0-liter turbocharged four-cylinder. A 2016 update replaced the 228i with the 230i, still four-cylinder but revised for more output and refinement. The six-cylinder cars are the enthusiast picks: the M235i used the turbocharged N55 inline-six, later succeeded in the M240i by the modular B58—one of BMW's finest modern engines. Rear-wheel drive is standard, with xDrive available across the range. Most cars pair the engine with the ZF 8-speed automatic, while manual transmissions were offered on select rear-drive models.

Ownership, Strengths & Weak Points

The F23 is a rewarding used buy: strong performance, everyday practicality, and a lively chassis. Standout strengths include the exceptional B58-powered M240i, secure xDrive traction, and a compact footprint that makes the car genuinely fun on back roads. As with any turbocharged BMW, watch for typical maintenance items such as cooling-system components, oil leaks from valve-cover and oil-filter-housing gaskets, and normal soft-top wear on higher-mileage cars. Enthusiasts cross-shopping open-top BMWs may also look at earlier convertibles like the E64 6 Series and its E63 coupe sibling for a larger grand-touring alternative. Overall, a well-maintained F23—particularly an M240i—remains one of the most engaging affordable convertibles BMW has built.
