Singapore GP: Lotus's Romain Grosjean vents frustration at Renault

Grosjean was hit by engine issues during the second qualifying segment, which the Frenchman ended as the slowest driver in 16th position.

Both he and team-mate Pastor Maldonado suffered turbo wastegate issues that meant they lacked full power during their qualifying runs.

Grosjean made his feelings clear after being hit by the problem, screaming on the radio: "I cannot believe it! Bloody engine! Bloody engine! We break our balls for this?"

The Frenchman admitted the frustration had got the better of him.

"I had it [the same problem] in FP3, twice in the lap, which wasn't too bad," Grosjean said. "Then it was just worse. That's why I was a bit annoyed.

"Everybody is working so hard. Then you go into qualifying and you know it's your best shot in a long time, and you know the race is crazy, and P13 is not that far from the points, and then you lose time on the straightline...

"I don't like to openly complain, but sometimes it's so hard for all of us. Everybody is trying to do their best.

"It's hard, it's hot, it's humid. We work hard. I take every single risk that I can on the track.

"Last year I was third in qualifying and that lap was probably as good as last year's in terms of driving. And that was 13th, and 13th is much better than 16th.

"It's just the amount of problems that we've had over the weekend, which is big. Sometimes driveability is not good.

"In free practice it was the downshift, and then this morning it was the same problem as in qualifying.

"We are asking for one clean lap."

Team-mate Maldonado went out in Q1 and will start the race from 18th position.
