Fabio Leimer has completed a test with Lotus as his prize from Pirelli for winning the 2013 GP2 Series.
Leimer, who is racing for Rebellion in the World Endurance Championship this season, completed 78 laps at Paul Ricard in the E20.
"It was an absolutely fantastic experience and I really enjoyed myself," said Leimer, who ran on Pirelli's demonstration tyres.
"In the morning we had a bit of understeer due to the conditions, but during the long runs in the afternoon I developed a really good feeling with the car and tyres."
"It was a great opportunity and I could certainly see the difference in the various compounds I tested.
"I’d like to thank Pirelli for this chance that will definitely help me in future. Now I’m just looking forward to driving a Formula One car again!"
Leimer previously tested a Formula 1 car at the end of 2011 when he sampled a Sauber.
