Red Bull Racing were formed in 2005 when the Jaguar team (formerly Stewart) was purchased for the sum of US$1 by the Austrian drinks giant Red Bull. A management team was put in place featuring Arden International Motorsport team principal, Christian Horner, as team boss. The team continued the existing partnership with Ford who provided their Ford Cosworth TJ2005 engine to power the RB1, Red Bull's first car as a constructor. Also retained was Christian Klien, now partnered by David Coulthard. On four occasions, Klien was replaced by Vitantonio Liuzzi, an arrangement made between the drivers before the season had begun. This arrangement produced moderate success in 2005, ending the season in 7th place with 34 points, an improvement of 24 points on the last Jaguar season in 2004.
