Lotus driver Romain Grosjean expressed his satisfaction after conducting a race simulation in his E21.
The Frenchman set the third fastest time in the morning and completed 119 laps.
"I think I’m ready for a sleep after so many laps in the car!"
"It’s good to see reliability today to add to the pace we’ve already seen in the car. We’re still at an early stage of development so it’s really promising to see where we are," he said.
"It was difficult out on track as temperatures were so low, but we’ve gained a lot of useful data. The 2013 tyres certainly feel different from last year’s but already we’re starting to understand them. I hope it’s dry tomorrow so we can get some more laps under our belt."
Trackside Operations Director Alan Permane added that it had been a perfect day for Lotus.
"From our perspective it was a perfect day. We ticked off every item on the checklist and even had time to spare at the end of the session," he said.
