[cars name="BMW"]‘s M6 convertible trades the coupe’s sweet carbon-fiber roof for a power-folding soft top, but even that lid is somewhat unconventional. As with the standard 6-series convertible, the M6’s folding top features a flared design and a vertical rear window that powers up and down independently from the roof. Putting the top down provides unfiltered exposure to the 500-hp V-10’s full song (which peaks at a sky-high 7750 rpm). Regrettably, as with the M6 coupe, BMW’s servo-shifted, seven-speed SMG manual is the only transmission available. Still, the combo will send the four-seat convertible from 0 to 60 mph in 4.5 seconds, according to BMW, making it essentially as quick as its hardtop sibling. The M6 convertible is expected to go on sale in November (turn the heat up high and keep that top down) at a price of about $103,000.
