Fantastic engines; awesome long-distance cruiser; high-quality interior; plenty of tech; available all-wheel drive
Less athletic than you might expect; useless back seat; convertible isn't offered with a retractable hardtop
The 2015 6 Series gets a standard digital instrument cluster and touchpad iDrive controller, while an M Sport exhaust system is standard on 650i models. Also, the automatic transmission gets a launch-control mode.
We're amazed by the 640i's fuel economy, but that's not what a car like this is all about. You might buy a 6 Series to reward yourself for a job well done or a life well lived, and the best reward is the fantastically powerful yet refined 650i. Find a BMW 6 Series for sale
The 2015 BMW 6 Series is offered as a coupe or a soft-top convertible in two trim levels: the 6-cylinder 640i and the 8-cylinder 650i.
The 640i coupe ($77,050) and 640i convertible ($84,550) come standard with a turbocharged inline 6-cylinder engine, 18-inch alloy wheels, adaptive xenon headlights with LED fog lights, a sport-tuned suspension with adaptive dampers, front and rear parking sensors, a tilting glass roof panel (coupe), keyless entry/start, a digital instrument cluster, leather upholstery, 10-way power front seats with driver memory settings, a power adjustable steering wheel, dual-zone automatic climate control, iPod/USB and Bluetooth connectivity, a 9-speaker audio system and the hard-drive-based iDrive infotainment system with a 10.2-in widescreen display, a touchpad-equipped controller knob, digital music storage, a navigation system and a rearview camera.
The 650i coupe ($88,350) and 650i convertible ($95,850) add a twin-turbocharged V8 engine, an available manual transmission, 19-in alloy wheels, a Harman Kardon audio system, 20-way multicontour power front seats with memory and Nappa leather upholstery.
Some of the 650i's extra features are available on the 640i as options. Notable add-ons include 20-in wheels, adaptive cruise control, side- and top-view cameras and a 16-speaker Bang & Olufsen audio system. The kitchen-sink M Sport Edition package contributes aerodynamic tweaks, M-design 19-in wheels, adaptive LED headlights, LED fog lights, high-gloss shadowline trim, black-painted brake calipers, dark chrome exhaust tips, extensive M interior modifications (including extended Alcantara and Nappa leather trim) and a full range of technology features.
The 6 Series model's back seat isn't big enough for passengers unless the folks sitting in front have short inseams. Even then, headroom is severely limited unless you're in the convertible and the top's down. Speaking of which, we can't complain about the vinyl roof's rapid power operation. It's important to note, however, that soft-tops are inherently vulnerable to break-ins and harsh weather in ways that retractable hardtops simply aren't.
As for cargo space, the coupe boasts a reasonable 13 cu ft., while the convertible offers 12 cu ft. with the top up and a couple fewer with it folded.

2015 Audi S5 -- The S5 coupe and convertible are much cheaper than their 6 Series counterparts, but they have many of the same traits. The S5 is fast and composed, with a beautiful interior and more nimble handing. We prefer its looks, too.
2015 Chevrolet Corvette Stingray -- The base Corvette Stingray is a true bargain at barely half the price of a 650i, and the convertible's a similarly excellent value.
2015 Porsche 911 -- The current 911 has morphed into more of a GT car, but it's still much more engaging than the sedate 6 Series. The 6er has a better ride, though.
Used Mercedes-Benz SL63 AMG -- The astoundingly capable V8-powered SL63 is ordinarily in a different price range, but a certified pre-owned example of this retractable-hardtop roadster could fall into 6 Series territory.
