F83 · M4 Convertible

What the F83 Chassis Is

The BMW F83 is the drop-top member of the F82/F83 M4 family, built from 2015 through 2020. Where the coupe carries the F82 code, the F83 designation is reserved exclusively for the M4 Convertible. It shares its bones with the F32 4 Series but receives the full M treatment: wider tracks, unique suspension geometry, a carbon-fiber-reinforced strut brace, and aggressive aerodynamic tuning. The result is a genuine M car that also happens to fold its roof away at the touch of a button.

You can confirm any F83's build details and options using our VIN decoder, which is especially useful given the range of packages and Competition-spec upgrades offered over the production run.

Models and Body Styles

In the US market, the F83 generation is refreshingly simple — a single model:

• M4 Convertible (2015-2020) — a two-door, four-seat convertible with a three-piece retractable hardtop

The retractable hardtop delivers coupe-like refinement and security with the roof up, at the cost of added weight and a smaller trunk when the top is stowed. For enthusiasts who want the fixed-roof experience and lower curb weight, the closely related coupe lives under a separate chassis code.

Engines and Drivetrains

Every F83 is powered by the S55, BMW M's 3.0-liter twin-turbocharged inline-six. Output starts at 425 horsepower, with Competition Package cars bumping that figure to 444 hp and adding retuned dampers, revised stability control, and a sharper exhaust note. Power reaches the rear wheels through either a 6-speed manual or a 7-speed dual-clutch (DCT) transmission — a rare case where the enthusiast's stick-shift dream survived into the turbo era. This is a true M powerplant in the lineage documented in our BMW DNA overview, a leap forward from the naturally aspirated units in earlier M convertibles like the E64 M6.

Ownership: Strengths and Weak Points

The F83 rewards owners with tremendous straight-line pace, an addictive turbocharged soundtrack, and the versatility of open-air motoring. As a used buy, it offers serious performance value.

Things to keep in mind:

• The hardtop mechanism adds weight and complexity — verify smooth, quiet operation before purchase
• S55 engines benefit from meticulous maintenance; budget for premium fuel, tires, and brakes
• Convertible-specific chassis reinforcement means it drives slightly softer than the coupe

Compared to the older grand-touring convertibles such as the E63/E64 6 Series, the F83 is far more focused and track-capable while remaining genuinely usable every day.
