Renault reserve driver Sergey Sirotkin sampled a 2017 new-spec Formula 1 car for the very first time on Wednesday in Bahrain, ending his day longing for more.
The Russian hopeful completed 90 laps in the French team's RS17, running through a range of suspension, tyre and aero programmes, and positing the ninth fastest lap of the day.
"It was quite a good, and quite a busy day, and it was great to be out in action as I’ve been waiting for this day a very long time!" said Sirotkin.
"I enjoyed every second of being in the car, even if the programme was not the most exciting for the driver.
"The car is amazingly quick and I noticed the difference in grip immediately from the previous generation.
"That said, you soon get used to the extra speed. I can’t wait to get to Sochi."
Renault sporting director Alan Permane was delighted with Sirotkin's contribution.
"Today went completely to plan. Sergey impressed us as he was quickly up to speed and didn’t put a foot wrong despite having not driven since the end of last year.
"As with yesterday, we weren’t chasing particular headline times for the day, rather building a basis for further pace at the forthcoming races and we’re confident that the work done here will be highly beneficial in that aim."
