F1 drivers and engineers canvassed Karun Chandhok for his impression of this weekend’s new grand prix venue in Korea, the Indian has revealed.

Chandhok, 26, contested the first half of 2010 with the HRT team, and was later deployed by Red Bull to the new – then incomplete – Yeongam layout for a demonstration in an F1 car.

So, as the only driver in the world to have completed real laps in Korea, Chandhok revealed to Reuters that title contenders Mark Webber and Jenson Button have asked him about the circuit’s nuances.

“You’d expect people to be calling, really,” said Chandhok, who is not travelling to Korea this week.

The report said technical people from various teams, and his former teammate Bruno Senna, also asked Chandhok questions about his laps in Korea.

“To be fair, a lot of people have very good simulators and they have a lot of faith in their simulators and simulation software,” he explained.

“I think a lot of them tend to believe that more than anything else.”

But he said Australian Webber spoke to him about Korea.

“Obviously he was very curious to see what I thought about the place and what the circuit was like,” said Chandhok.

And a more recent discussion was with Button.

“We were chatting about this and that and he was quite curious about Korea,” added the Indian, revealing that the McLaren driver asked him about the camber of the corners.

“I think some of that stuff is not so apparent until you get there. So he had questions about that sort of stuff,” said Chandhok.
