Tonio Liuzzi is predicting a very tough weekend for him after failing to complete any significant running in Friday practice.
The HRT driver managed just four laps in the afternoon session before his car suffered a water pressure problem. Liuzzi had been replaced by Narain Karthikeyan in the morning, so the Italian completed nearly no running today, and he believes he will pay the price during the weekend.
"Unfortunately, today was too short to have any information on the car," said Liuzzi. "After three laps we had an issue with the water pressure so we had to stop the car on the track.
"Two laps aren't enough to judge how the car is but the good thing is that in those two laps we were up to pace. It's a shame because this is a circuit where you need to do kilometres to get some rhythm going so it won't be an easy weekend after this short practice session but we'll see where we are tomorrow morning."
Teammate Daniel Ricciardo enjoyed a better session, the Australian finishing in 22nd position after over 60 laps today.
"My day went pretty well; luckily it went better than Tonio's, who unfortunately had to retire early on. So I'm happy to have completed both sessions. The car doesn't feel too bad but we're still quite a bit off the pace of our closest rivals so we need to make a big step to close the gap on them.
"I'm not sure where we'll find this lost time; some of it could be in my driving. But we all need to work together on this to close that gap and hopefully we can achieve it to have a competitive race."
