Even though he covered 74 laps on Friday in Austria, Romain Grosjean failed to find a solution to the handling and set-up problems he experienced.
The Lotus driver finished Friday's second practice at the Red Bull Ring down in 19th place, even slower than Marussia's Max Chilton.
It was a disappointing day for him as no matter how much running he did, Grosjean was unable to find the pace needed on his short runs.
His 1:12.262 was 2.720s slower than the afternoon's P1 time.
The Frenchman said: "It was good to discover the circuit at the wheel of the E22 for the first time today.
"We have done a lot of work, completed 74 laps however it is fair to say that we have also struggled in the sessions.
"I wasn't happy with the handling and the set-up of the car but we will work hard to rectify the different areas that need working on.
"It was good to learn that the longer run pace was stronger, we just need to unlock that pace for qualifying tomorrow."
