Red Bull to run heavily revised RB8 in Australia 8 March, 2012 Christian Horner with Adrian Newey and Sebastian Vettel Mar.8 (GMM) Christian Horner has denied reports that Red Bull Racing is considering taking the old specification of its 2012 car, the RB8 ‘A’, to Melbourne for the season’s opening race. The reigning world champions arguably set the early pace thisWinter, but apparently struggled once a big package of upgrades – essentially a ‘B’ chassis – was brought to the final Barcelona test. Sebastian Vettel’s final day of running was dismissed by team advisor Dr Helmut Marko as no less than “sh1t”, ramping up speculation the team might revert to the initial RB8 specification. But team boss Horner told BBC radio: “It’s amazing how these things get construed. “Those [Barcelona] upgrades seem to be working OK, and they’ll certainly be on the car in Australia in ten days’ time.” Subbed by AJN.
