LEWIS HAMILTON'S chances of winning in Singapore on Sunday have been given a major boost as his McLaren will feature a host of new tweaks.
And the reigning world champion vowed to go all-out for victory.
McLaren team principal Martin Whitmarsh said: "For this race, we are introducing our last major upgrade package of the season before fully devoting our efforts and resources towards next year's car."
Hamilton, now out of the title chase after starting the season with an uncompetitive machine, said he would push hard after playing safe in last year's inaugural night race.
He added: "I remember my race in Singapore last year was all about damage limitation.
"I was driving with one eye on the world championship and wasn't going to take too many risks. I was happy to finish on the podium.
"This year it's very different. I know I'm out of the title hunt and I want to attack these last four races, pushing for as many victories as I can."
At the last race in Italy, Hamilton crashed on the last lap while chasing championship leader Jenson Button for second place.
But he won in Hungary in July and finished second in Valencia in August.
