With sharp styling and performance to match, the 2013 BMW M6 coupe and convertible is easily one of the best touring cars on the market. Exceptionally powerful engine; responsive dual-clutch automated manual transmission; wide range of comfort and performance settings; roomy front seats. After a two-year hiatus, the M6 is back. Besides the benefits that come with the new 6 Series (sharper styling, roomier front-seat accommodations and more useful trunk space), the M6 provides more power under the hood — a lot more power. Output from the M6's twin-turbo V8 even tops that of its predecessor's high-revving V10 engine. With 560 horsepower and 500 pound-feet of torque at your command, one might assume that the M6 is a handful to drive and a bit of an untamed beast. In classic M style, though, all of this power has been beautifully balanced by not only a well-tuned chassis but also an abundance of electronic assistants which together deliver a manageable and civilized ride. The 2013 BMW M6 is available as either a coupe or convertible, both of which are offered in one, very well-appointed trim level.
