Lewis Hamilton feels he is driving better than ever

The Briton's title challenge has been struck down by poor reliability since his dominant win in the Italian Grand Prix last month.

The McLaren driver suffered a gearbox failure while leading in Singapore, rear suspension issues in Japan which limited him to fifth position and an anti roll-bar failure in Korea last time out that meant he only scraped a point for tenth position.

This poor run has realistically eliminated Hamilton from contention in the 2012 drivers' championship, but he insists he will deliver on his form at the Buddh International Circuit this weekend.

"I feel I've been driving better than ever recently - even if the results haven't quite shown it - so I'm headed to India determined for another good result," he said.

"I think we'll have a car that's a match for the circuit and I can't wait to get out there and start practicing on Friday."

McLaren's constructors' title hopes took a hit in Korea with Jenson Button also being taken out on the first lap, and the team is now 83 points behind leaders Red Bull in the standings.

But team principal Martin Whitmarsh is optimistic McLaren can recover some ground over the India/Abu Dhabi double-header.

"Our two weekends in Japan and Korea weren't particularly prosperous. But while fortune certainly didn't smile on Vodafone McLaren Mercedes during those two races, it's proof if it were needed that no team or driver is immune from tides of good or bad luck," he said.

"Of course, luck flows both way, and I'm positive that, after two disappointing races, this next double-header will be a more profitable affair for Jenson, Lewis and the whole team."
