Mercedes Benz, in their efforts to appeal to a younger demographic, is developing smaller models.  

At the Frankfurt motor show this week, Mercedes unveils its B-class compact model.  The German automaker also has plans for an A-class hatchback, a small coupe and a compact sport-utility car.  Mercedes has spent billions of dollars developing these smaller, sportier vehicles in the hopes of attracting younger buyers.  This will keep them competitive with other auto manufacturers such as Mini Cooper and Audi.  These smaller cars will also have an easier time meeting emission standards, which are tightening.
