Following Christian Klien's decision to pursue other options within Formula One, Red Bull Racing has agreed to release him from his contract with immediate effect.
. The team's test and reserve driver Robert Doornbos will contest the last three races of the season for the team, alongside David Coulthard.
"It's fantastic to know that I'm going to be racing again, I'm really looking forward to it. Friday testing and helping the team this year has been great experience, but to get back out on to the race track on Sunday is what it's all about. I've got to know the guys at Red Bull Racing really well this season, so I'll be working with them all closely to do the best job I can for the team and myself."
