Florence: Even split seconds could not separate Romain Grosjean and Kamui Kobayashi at the top of the Formula One test timesheets at Italy's Mugello circuit on Wednesday.
After a day of rain and thunder on Tuesday, the sun shone over the track north of Florence and allowed the 11 teams present to put down some serious mileage.
Lotus' Grosjean and Sauber's Japanese driver both posted a best time of one minute 21.603 seconds.
"It's always good to end the day on top but we have to remember that, in testing, lap times mean very little," said the Frenchman, who took his first podium finish for Lotus at the last race in Bahrain when he was third.
"Having said that, the car felt great and I was very comfortable from the start."
Mercedes' Michael Schumacher, a regular at the Ferrari-owned circuit in his glory years with the Italian team, did the greatest distance with 144 laps or 755km and was eighth quickest.
"We were able to gather really a lot of data and like this we are learning more and more about our car which is absolutely positive," said the 43-year-old seven times champion.
