Former BMW tester Christian Klien has joined HRT as the Spanish team’s reserve and third driver.
He will participate in the Friday practice sessions in Barcelona this weekend.
Klien made his F1 debut at Jaguar in 2004 alongside Mark Webber. The Austrian remained at the team when it became Red Bull, initially sharing his drive with Vitantonio Liuzzi, but was dropped late in 2006 and replaced by Robert Doornbos.
He has started 46 F1 races and last appeared at a Grand Prix weekend driving for Honda as a substitute for Jenson Button in practice for the 2007 British Grand Prix.
Klien will continue to drive for Peugeot in the Le Mans Series. He joins Sakon Yamamoto as HRT’s two reserve drivers. Team principal Colin Kolles said:
He is a young and fast driver. I have been keeping a close eye on him since his first races in the ADAC series as I believe he has great potential. We look forward to having Christian alongside us in Barcelona later this week so he can spend some valuable familiarization time with the team. As a young team we are looking or drivers who can grow with us.
