As the Formula 1 teams head back to Europe, Red Bull took time out to entertain fans in Austria. A crowd of 60,000 turned out to watch Daniel Ricciardo put his RB8 through its paces in a specially-constructed arena in front of the historic Vienna Rathaus. Marking the return of the Austrian Grand Prix to the F1 calendar, he gave fans a doughnut master-class, while junior GP2 driver Pierre Gasly shredded the tyres of a borrowed NASCAR racer. Ricciardo and Red Bull will be back on the starting grid at the Spanish Grand Prix on May 10.
