The four versions that comprise BMW’s 6-Series include 650i coupe and convertible, and the V-10-powered M6 coupe and convertible. All models share a common profile, a 2+2 seating arrangement, and truly impressive performance, along with hefty 4,000-pound curb weights and a heavy feel at the controls.
Last year BMW reshaped the 6-Series' front and rear ends and decklid but it still looks thick and squat, especially from the back. ForbesAutos considers it a “sleek design,” and Car and Driver calls its “unique looks” a “high.” Cars.com says “the humplike trunk, probably my least favorite attribute, blends in from most viewing angles.” Edmunds refers to its “controversial styling” and defers on insults: “let's just say the 2009 BMW 6-Series has a great personality.”
There are additional style features, such as "taillights and front turn signals lit with LEDs, a third taillight integrated into the spoiler on the trunk hatch, and lengthier reverse lamps and reflectors," says ForbesAutos. Car and Driver points out the "vertical face of the trunklid grows more concave" as it curves up "to meet the trailing edge of the plateau." Road & Track notes the "unique profile" of the BMW 6-Series "remains essentially unchanged."
Cars.com says, “Side sills are aerodynamically contoured. Forged aluminum 19-inch wheels were developed specifically for the M6, and an 'M' logo is present in the ornamental side slats.” The M6 edition gets a carbon-fiber roof in coupe trim. “Changes to the basic 6 Series design include a modified front air dam with large secondary intake openings that provide additional engine-cooling air.”
The interior of the BMW 6-Series is more along the lines of what you’d expect from BMW. The 6-Series' "leather-wrapped dashboard comes across as a simplistic and elegant design festooned with add-on pods for iDrive," says J.D. Power. Cabins within the 2009 BMW 6-Series models possess an "elegance" that matches the "lofty pricing," says ConsumerGuide. Edmunds agrees, deeming the interior "elegantly crafted," though the cockpit has an "austere feel." Car and Driver calls minor tweaks to the BMW 6-Series "barely worth noting." Stereo controls are "minimalist" in this 2009 BMW, though, and without preset radio buttons, drivers are forced to contend with the iDrive, warns MyRide.com.
