F06 · 640i Gran Coupe

What the F06 Chassis Is

The BMW F06 is the Gran Coupe body style within BMW's F06/F12/F13 6 Series generation, sold in the US from 2013 through 2019. Where the F13 was a two-door coupe and the F12 a convertible, the F06 added a frameless-door four-door layout that BMW positioned as a lower, sportier alternative to the 7 Series. It shares its underpinnings with the contemporary 5 Series-derived architecture and continues the grand-touring philosophy first established by the E63 and E64 coupes and convertibles.

Models & Body Styles

Every F06 is a four-door Gran Coupe, offered in rear- and all-wheel-drive forms:

• 640i Gran Coupe and 640i xDrive Gran Coupe — inline-six power
• 650i Gran Coupe, 650i xDrive Gran Coupe, and 650xi Gran Coupe — V8 performance
• ALPINA B6 xDrive Gran Coupe — the tuned, luxury-focused super-sedan
• M6 Gran Coupe — the full M-division flagship

Engines & Drivetrains

The 640i models use BMW's turbocharged N55 3.0-liter inline-six, delivering smooth, efficient thrust ideal for long-distance touring. The 650i, 650xi, and ALPINA B6 rely on the twin-turbo N63 4.4-liter V8, with ALPINA extracting formidable output for effortless high-speed cruising. The M6 Gran Coupe is powered by the high-strung S63 V8, paired with the M-tuned dual-clutch transmission. Most F06s use an eight-speed automatic, with xDrive all-wheel drive widely available.

Owning & Buying an F06

The F06 offers genuine four-seat usability with true coupe presence, making it a compelling used luxury buy. Prospective owners should budget for the N63/S63 V8s, which reward diligent maintenance—cooling system, coil packs, and oil-consumption items deserve attention. The N55-powered 640i is generally the most cost-conscious choice.

Strengths and Watch Points

• Strengths: striking styling, refined ride, strong turbocharged powertrains, and available xDrive traction.
• Watch points: V8 maintenance costs, complex electronics, and premium tire and brake expenses.

For enthusiasts wanting a rarer grand tourer with everyday practicality, a well-documented F06 remains one of BMW's most elegant used flagships.
