"I'm feeling really confident. I had quite a good race here last year and we've been consistently on the pace in testing; never out of the top ten," he said.
Both drivers are wary of the weather, with rain greeting the GP2 and F1 drivers and teams touching down in Istanbul on Wednesday and the forecasts suggesting more of the same ahead.
"It's been wet here so far, so I think we could have an interesting weekend ahead of us if the rain continues, said Chilton. "Istanbul is a fairly high speed circuit, especially the famous turn 8 which is challenging, especially for the tyres as it's a long loading corner. The track is also quite undulating, which means that there are a lot of blind corners and crests.
"That will also make it more interesting if it's wet as there could be quite a bit of standing water," Chilton added. "Wet or dry I'm really looking forward to this weekend."
"The weather could be a big factor this weekend," agreed Aleshin. "But for sure we have a team that can deal with the changing conditions and I'll be pushing to do my best as well."
