The Red Bull RB3 was an Formula One racing car designed and constructed by Red Bull Racing to compete in the 2007 Formula One season. Powered by a Renault V8 engine, the RB3 was driven by David Coulthard and Mark Webber. While it showed improvements over the previous year's car, the RB3 was ultimately not competitive enough to challenge for top positions against cars from Ferrari, McLaren, and BMW Sauber.
