Mercedes-Benz celebrates numerous world premieres at the 2011 Frankfurt International Motor Show. The centrepiece of its show presentation is the new Mercedes-Benz B-Class. Another highlight will be the F 125! The research car demonstrates how in the long term entirely emission-free individual mobility can be made possible in the luxury segment. Roadster performance in perfection is shown by the new SLS AMG Roadster, which also is making its first public appearance at the show. Two roadsters also have their world premieres, the SLK 250 CDI and SLK 55 AMG
