Newey could hardly influence the design of the 2006 car and Red Bull's season started with poor results, having scored only two points from six races. However, the team's lead driver, David Coulthard, who had driven Newey-designed cars for years for both Williams and McLaren, managed to secure third place and six points in the Monaco Grand Prix. Although assisted by retirements of other competitors, indications were that the team was eventually beginning to pick up where it left off in 2005 when they finished a close seventh overall. The 2007 Red Bull of his design was powered by the Renault RS26 engine as the Ferrari 056 contract was transferred to Scuderia Toro Rosso, Red Bull Racing's "B team". The car was reasonably fast but rather unreliable, with each driver retiring seven times in a season of 17 races. Nevertheless, with the disqualification of McLaren-Mercedes, Red Bull achieved fifth place in the 2007 Constructors' Championship as targeted.
