It was another quiet race bringing up the rear for HRT.

While their closest rivals were able to get away with two stops, both HRTs had to make three due to high tyre wear.

“We struggled the whole weekend with the tyres, especially on the rear end of the car” said team principal Colin Kolles.

“We had to go for a three stop strategy since the wear of the tyres was too high; our main competitors were on two stops. The pace overall was good but due to the additional stop we could not gain positions.”

Narain Karthikeyan

Finished in his customary last position after dropping back with a flat-spotted tyre early in the race: “At the beginning I was trying to keep with the pack, with Liuzzi and [Jerome] d’Ambrosio, but after seven laps I locked the front and after that I had a lonely race.”

Karthikeyan became the first driver to finish a race in 24th place.
