Adrian Sutil was left frustrated after yet another retirement following his early exit from the Chinese Grand Prix.
The Force India driver's car developed a problem soon after the start of the race and the German was forced to retire after 14 laps.
It was Sutil's 11th retirement in 17 races.
"Very early on in the race my car developed a problem," said Sutil. "I couldn't select gears anymore and had to pull off just before the main straight and park the car.
"Until that point I was quite happy in the car, even though the traction and grip was very low so it's disappointing not to finish yet again. I really hope for more in Brazil now."
Teammate Giancarlo Fisichella managed to make it to end of the race, albeit in last position a lap down.
"We knew our pace was not really good enough today so we just tried to find a different solution to gain places," said Fisichella. "We went for a one-stop strategy but I was really struggling with the grip to start with.
"In the last 10 laps before the end of the race I was able to do reasonable laptimes, but it was a fairly lonely race for me at that point. Anyway, we now go onto Brazil and the last race."
