Newey says late 2013 Red Bull is not a problem 7 December, 2012 Dec.7 (GMM) Red Bull designer Adrian Newey has confirmed reports that the team’s RB9 chassis, the successor to his F1 World Championship title winning RB8 will be launched slightly late. Red Bull team boss Christian Horner admitted this week that progress with the Renault-powered RB9 is running “a little late”. “We will be ready later than we would like,” Newey is now quoted by Spain’s El Mundo Deportivo. “We had to focus until the last moment on development of the RB8 in order to retain the two titles. “But it’s not a serious problem, because the RB9 is an evolution of the [RB8].” Subbed by AJN.
