The 6-series is the next BMW in line for a redesign, as evidenced by this prototype captured during winter testing in Scandinavia. Codenamed F13, the new 6-series will launch in late 2010 as a 2011 model. As with the current model, the new car will share much of its platform and mechanical hardware with the next generation 5-series.
The canvas drop-top is likely a ruse. Our spy photographer noted that it didn't fit well, and with both the Z4 and 3-series convertibles having been given folding metal hardtops, it's likely the new 6-series convertible will go the same way. The shape of the rear window suggests a hardtop.
The sheetmetal of the new 6 Series will, much like that of the redesigned 2009 7 series, be inspired by the 2007's Concept CS. Although European buyers will be offered diesel versions, U.S. cars will be powered by the twin-turbo V-8 currently in the 7 Series and X6. The engine will drive the rear wheels through the new ZF eight speed automatic transmission.
The new 6-series is may make its debut at the 2009 Frankfurt Motor Show in September, prior to its 2010 launch. A new M6 is expected to follow in early 2011, though its V-10 could make way for a more aggressively tuned version of the twin-turbo V-8.
