Nico Hulkenberg was left "quite frustrated" after he was punished for the collision with Felipe Massa in Singapore while the Williams driver is adamant the German was at fault.
Both drivers were running safely in the top 10 when the first round of pit stops came up, and Hulkenberg was first to get a fresh set of tyres with Massa doing likewise a lap later.
However, they made contact as Massa was about to rejoin the track. Although Hulkenberg appeared to be ahead of the Williams driver, stewards found that he cut across and gave him a three-place grid penalty for the Japanese GP.
The Force India driver, whose car was too badly damaged to continue, was not happy with the punishment.
"I’m quite frustrated for two reasons, obviously," he is quoted as saying by Motorsport.com. "The race looked promising, so to finish it that early with that incident is very disappointing and annoying.
"I was on the racing line, ahead going into Turn 3, and he’s coming out of the pits and touches me on the back. It’s a bit strange, I don’t understand also why the penalty is given right away and they weren’t even listening to what the different views were.
"I saw him coming out of the pitlane, but afterwards I knew I was in front. And then I got hit in the back."
Massa continued after the incident, but he also retired later in the race and he feels "for sure it was Hulkenberg's mistake".
"I was going out of the pits, and I was inside [for the corner], so braked inside, he braked outside, he just turned like I wasn't there and he hit me," he said. "Even if he stayed on the right, and left me the space, it would have been possible to get better traction and overtake me at the next corner.
"I don't understand why he turned in on my car, so for sure it was his mistake."
