The latest in the string of car launches ahead of the 2008 Formula One World Championship is the Red Bull-Renault RB4, which was quietly unveiled – rather contrary to typical Red Bull glitz – while undergoing testing at the Jerez track in Spain.
Stability is what Red Bull Racing is banking on this year. An evolution of last year's RB3, the new RB4 is the second Red Bull car designed by celebrated technical director Adrian Newey, powered by the same Renault engine and driven by the same experienced drivers (David Coulthard and Mark Webber) from last season, when reliability issues cost the team 24 points in the constructors' championship.
Red Bull Racing also took the opportunity to announce another Sebastien as their third driver. Sebastien Buemi – not to be confused with the Sebastien Bourdais or Sebastian Vettel, who will be driving for RBR's Ferrari-powered B-squad Scuderia Toro Rosso – comes on as a test driver and stays on reserve in case Coulthard or Webber can't race, while simultaneously driving for Arden Racing in the GP2 feeder series.
