As the hottest-performing member of BMW's current lineup, the 2009 M6 picks up where the regular 6 Series leaves off, adding more power, edgier styling details and enhanced handling capabilities to an already impressive baseline mix. Combining a Formula One-inspired 500-horsepower V10 engine, M-spec chassis tuning and distinctive interior appointments with a choice of Coupe or Convertible configurations, this stunning 2+2 from BMW's legendary Motorsport division offers buyers with a six-figure budget an ultimate grand touring experience. Key rivals for potential owners to ponder include the Aston Martin V8 Vantage, Jaguar XKR, Maserati GranTurismo S, and Porsche 911 Turbo, although in this rarefied automotive atmosphere, everything from a Corvette ZO6 or Nissan GT-R to AMG versions of the Mercedes-Benz CL-Class and SL-Class also could end up on an individual's short list.
