Three World Premieres for BMW at the 2011 Detroit Show

In less than three weeks from now, the 2011 North American International Auto Show [NAIAS] will open its doors at the Cobo Hall in Detroit, and BMW will be there with three world premieres. These include the new 6-Series Convertible, the punchy 1-Series M Coupe and the revitalized for the 2011MY, 1-Series Coupe and Convertible. We've already had a chance to see all three models, so no surprise there, that is, unless the Bavarians have something else up their sleeves.

In more detail, the first version of the next generation 6-Series sports car is the Convertible, which will launch as the 650i equipped with a 400HP 4.4-liter turbocharged V8 linked to either a six-speed manual or an 8-speed automatic transmission. The new 650i Convertible will go on sale in the spring of 2011 as a 2012 model for the United States, while the Coupe model will follow shortly after.

Next in line is the beefed up 1 Series M Coupe boasting a twin-turbocharged, all-aluminum, 3.0-liter inline-6 with 335 ponies driving the rear wheels through a standard close ratio 6-speed manual transmission. The new 1 Series M Coupe will be available in limited quantities next spring.

Finally, the 1 Series Coupe and Convertible enter the 2011 model year with some subtle styling tweaks and interior improvements, while keeping the same hardware. As with the other two BMWs, the updated 1s go on sale in spring of 2011.
