It appears that the Ralf Schumacher-Mucke Motorsport collaboration may not be competing in 2012. In a preview of the 2012 season, the latest issue of The GP2 Insider states that “twenty-five of the twenty-seven seats available have been filled”. One week from the first race in Barcelona, RSC Mucke is the only team not to have confirmed any drivers for the season; both Jenzer and Trident still have one vacancy apiece.
This is yet to be confirmed, though. A few months ago a proposed set of rules was put forward that would see teams reduced to two-car outfits, with a third car optional. Whether or not these changes were accepted is unknown, but if they were, then it is equally-plausible that RSC Mucke, Jenzer and Trident will each run two cars, rounding the field out at the aforementioend 27 cars.
