Time to hit the gas pedal. There will be no compromises in this battle of the pros. The Audi RS 5 DTM 'M. Ekstrom, No. 5' and the Audi RS 5 'R. Rast, No. 33' provide lots of action in the new Carrera GO 'DTM Master Class' set. The big race is on an 8.9-metre Carrera GO racing circuit that tests the limits of drivers of all ages. The two loops, a steep bend and a fly-over are great fun and require fans to master every handset skill in the book.
