What the F13 Chassis Is

The BMW F13 designates the coupe body of the third-generation 6 Series, produced for the US market from 2012 through 2017. It arrived as the fixed-roof companion to the convertible (F12) and later the four-door Gran Coupe (F06), sharing much of its architecture with the contemporary 5 Series lineage that preceded the F10. Longer, lower and wider than the outgoing E63 coupe, the F13 leaned harder into the grand-touring role while keeping BMW's rear-biased driving character intact.

Models and Body Styles

All F13 cars are two-door coupes. The US lineup covered a clear hierarchy from six-cylinder comfort to full-blown M performance:

Engines and Drivetrains

The 640i pairs the smooth N55 single-turbo 3.0-liter inline-six with either rear-wheel drive or xDrive all-wheel drive. The 650i steps up to the N63 twin-turbo 4.4-liter V8, offering effortless torque befitting a grand tourer. At the top, the M6 uses the S63 high-output twin-turbo V8, transforming the coupe into a serious 500-plus-horsepower machine. Most F13s use ZF's eight-speed automatic, while the M6 offers a seven-speed dual-clutch transmission. This layering of engines is a good illustration of how BMW builds a range within a single platform—more in our BMW DNA overview.

Owning and Buying an F13

The F13 delivers a compelling used-car proposition: striking looks, a premium cabin and strong performance for the money. As with any modern turbocharged BMW, buyers should budget for maintenance rather than assume it. The N63 and S63 V8s reward diligent oil service and cooling-system care, while the N55 six is generally the simpler, more forgiving choice. Look for complete service history, healthy tires and brakes, and functioning electronics across the large iDrive-equipped dash.

Strengths and Considerations

Highlights include a genuinely refined ride, potent drivetrains and everyday usability that its E64 predecessor couldn't match. The trade-offs are typical of a heavy luxury coupe—higher running costs and thirsty V8s. Chosen carefully and maintained properly, the F13 remains one of the most rewarding modern BMW grand tourers to own.
