The Austrian – former test driver for Honda and BMW Sauber, and former racing driver for Jaguar and Red Bull – made his HRT debut in the opening practice session of the Spanish Grand Prix after being confirmed at the squad just a week before.
The team’s other test and reserve driver, Sakon Yamamoto, took the driving duties at the Turkish Grand Prix.
Neither Klien nor regular drivers Bruno Senna or Karun Chandhok have driven on the Valencia circuit at all, so the team will be pinning its hopes on Klien to find an ideal chassis set-up to benefit the rookie drivers.
The car, as yet, still remains undeveloped since the start of the season, and it remains all the more impressive that they have been able to keep pace with the rest of the grid in spite of this.
“It is the exact same chassis I drove in Barcelona. Unfortunately, there are no major upgrades yet,” Klien confirmed.
“It is difficult when you are five or six seconds off the pace, but we are moving forward. And I am quite thankful to the team to give me this opportunity to prove my worth.”
Klien confirmed that he still harbours hopes for a full-time return to a racing seat.
