It’s no secret that former Formula One driver Ralf Schumacher has recently tested a DTM Mercedes at Estoril. Meanwhile, a bunch of new DTM teams were testing at Mugello without any media attention.
One grey Audi Sport car (apparently driven by Alan McNish) was joined by several unknown cars, one of them fielded by Audi Sport Spain. The other cars were driven by unknown drivers looking to make their way into the 2008 DTM season.
