Singapore - Formula One in general and the Renault team in particular must restore faith in the sport when it returns to last year's crime site for the Singapore Grand Prix on Sunday. The race comes six days after Renault received a suspended two-year ban from racing and their former boss Flavio Briatore was banned indefinitely over a deliberate crash of their then driver Nelson Piquet Jr to allow teammate Fernando Alonso to win.
It was one of the most infamous incidents in a sport rich with intrigue.
The Renault team is now headed for the rest of the season by former technical director Bob Bell as it aims to put past behind and aims "to concentrate on the future."
Alonso is not the favourite to win the only night race on the calendar again as that role is likely to go to Brawn GP.
Rubens Barrichello and Jenson Button claimed a convincing one-two finish in Italy and seem determined to fight out the title among themselves.
The Briton Button tops the bill with 80 points into the final four season races and the Brazil veteran Barrichello has 66. German Sebastian Vettel is a distant third with 54 points and his Red Bull team-mate Mark Webber has 51.5.
Barrichello has won two of the last three races while Button's confidence is back after making the podium following a five-race drought.
The five-time season winner Button insists he doesn't feel any pressure as the title race comes down to the wire.
"I know I'm in a very good situation, I am driving the best car on the grid at the moment, and I have probably got one of the most competitive team-mates on the grid at the moment.
"So there are lots of positives and a couple of negatives there, but why shouldn't I be positive? I have got a 14-point lead with four races to go. That's it really," said Button.
Button has not fully written off the Red Bulls and Vettel will not throw in the towel even though it will be tough to make up 26 points in four races.
"It's true the gap is quite big and it will be very difficult to catch up, but be sure we will try. I will fight to the last breath and minute," said Vettel.
Vettel's task is even more difficult because he used all eight engines he was allocated for the season. He can rotate them, but another replacement would lead to a 10-place drop on the grip and ruin is chances for good.
The action on the 5.067-kilometres street course starts on Friday with two rounds of free practice. Qualifying is Saturday and the race on Sunday.
It remains to be seen how much the "crashgate" scandal overshadows the racing, or the growing speculation that Alonso will move on to Ferrari next year to replace ex-champion Kimi Raikkonen.
The issue will not be settled in Singapore as Ferrari president Luca di Montezemolo said: "We are mulling the best choice but we still have time. We will decide in a few weeks."
