was attractive to Red Bull because of his American nationality which would raise the profile of both Red Bull and Formula One in America, a market where the sport has traditionally struggled to make an impact. Ferrari engines (2006) 2006 season On 23 April 2005, the team announced a deal to utilise customer Ferrari engines in . This coincided with a rule change mandating the use of V8 engines, making it likely that both Red Bull Racing and Ferrari would use the same specification engine. Red Bull Racing continued to use Michelin tyres, rather than the Bridgestones used by Ferrari. On 8 November 2005, Red Bull Racing hired Adrian Newey, the highly successful McLaren technical director. On 15 December 2005, the team's second car, the Red Bull RB2, hit the track for the first time. David Coulthard completed a handful of laps of the Silverstone circuit in England, and declared the new car was a "sexy looking thing".
