Nico Hulkenberg celebrated what he labelled as a "mega" result after finishing in sixth position in the Korean Grand Prix.
The Force India driver completed one of his strongest races of the season after battling with Romain Grosjean and Lewis Hamilton during the event.
Hulkenberg's race highlight came when he managed to overtake both men over two corners to move into sixth position.
The German admitted the move had left him with a smile on his face.
"That race was a lot of fun and it's great to get such a mega result," said Hulkenberg.
"It wasn't easy though, and for most of the race I had the Lotus of Romain [Grosjean] pushing me and some great battles.
"Even the first pitstop was very close with Romain, but the team did a great stop because it was important to stay ahead at that stage.
"I think the best moment of the race was the fight with Lewis [Hamilton] and Romain in the final stint when I got ahead of both of them in turn four.
"They both went to the inside so I just saw the opportunity to use the outside line and made the move work. That certainly put a big smile on my face.
"So a very positive day, an amazing job by the whole team and lots of positives to take as we head to India for our home race."
Team-mate Paul di Resta, on the other hand, endured a difficult day, finishing in 12th position.
The Scot admitted his chances of a good result had been compromised on Saturday, when he qualified in 14th.
"A tough race in many ways and it's fair to say that the result in qualifying hampered us quite badly," he said. "We expected the supersoft to be a better race tyre and so we saved it for the second stint.
"As it happened, the soft tyres did not last long enough at the start of the race and when I switched to the supersofts they started graining straight away.
"So we were not on the ideal strategy and that impacted the whole race, and after that I was always struggling with traffic and couldn't make any progress.
"On the positive side the car seemed competitive here with the points for Nico, but it's just a bit frustrating that we couldn't maximise it."
