For the second day running seven-time world champion Michael Schumacher has set the fastest lap in Ferrari's testing session in Barcelona.
Schumacher impressed in testing for the second day running
The German, who says he has no plans for a competitive comeback, is helping the team as a technical advisor.
They are using his experience of cars without electronic driver aids as such systems will be banned next year.
"It's good to see I'm still able to do it. It was great fun and I really like it a lot," said the German.
On Tuesday Schumacher topped the unofficial timesheets at the Circuit de Catalunya, completing 64 laps in the F2007 car with a fastest lap of one minute 21.922 seconds.
His best time on Wednesday was 1:21.489.
"It took me a bit of time at first, maybe two laps, and then I was back into the groove," said the 38-year-old.
"I have to say I surprised myself I was so quickly on it again."
"It was probably a bit like being a little kid. I felt like I did when I was 18 again, but being out on the track is still a very good feeling."
Schumacher had not taken part in a test since he retired in October 2006, though he did drive the F2007 for a few laps in the wet at Ferrari's Fiorano track at the end of last month.
His times are likely to catch the eye of plenty of team bosses, but Schumacher insists he has no intention of returning to racing.
"I don't think so," he said.
"There's nothing free at the moment."
This is not strictly true, as Ferrari's bitter rivals McLaren have a vacancy, and Toyota are looking for a replacement for his brother Ralf.
"It's probably a one-off," Schumacher's spokeswoman told BBC Sport when his input in the sessions was announced.
"Michael does not intend at all to go back to F1.
"He's testing just as part of his contract, which is to help Ferrari in whichever area he can.
"He is much more experienced than the other drivers in cars without electronic aids, this will be good input for Ferrari."
Schumacher retired from F1 at the end of 2006 after winning 91 Grands Prix in the most successful career in the sport's history.
The German attended several races this season in his new role as Ferrari technical adviser.
The team won both the drivers' title with Kimi Raikkonen and the constructors' championship this year.
F1's rules are changing next season, with the introduction of a common electronic control unit (ECU) to be used by all teams.
The new ECUs will not include electronic driver aids such as traction control, which was re-introduced to the sport in 2001.
Although Schumacher said in May he had no desire to step back into a F1 car, team boss Jean Todt made it clear the offer was always there.
"Todt said that if Michael had the desire to drive the car, he would be happy to fulfil it," said Schumacher's spokeswoman.
"It's half for pleasure, half for technical reasons."
