Romain Grosjean is expecting an emotional final race weekend at Lotus as he brings down the curtain on his 10-year association with the Enstone operation.
Grosjean, who will switch to Haas next year, joined Renault's driver development programme prior to the 2006 season and became the outfit's test driver in 2008, graduating to a race seat mid-2009.
Grosjean was not retained by the operation after Renault's exit but, having won the GP2 title, he returned to the team under its Lotus guise as a test driver in 2011 and has occupied a race seat since 2012.
"It’s the first time of my career that I have had to change teams in Formula 1, so it’s something new," he said.
"The first time I went to Enstone was September 2005, as one of the driver development and I learned everything from there.
"So it’s going to be… switching off the car on Sunday, jumping out of the E23 and thinking that was the last race with the team is certainly going to be quite hard.
"On the other hand I really want to push hard all weekend long to score good points, do a good result, thank the guys for all the support, through tough times, better times as well and I think we did both learn from those years, so it was a nice experience.
"[I'm] very much looking forward to the next one as well, it’s going to be very exciting with Haas. It’ll be good to have a good weekend and say goodbye in a proper way."
