Hamilton cautious on Hungary chances

LONDON, England (CNN) -- Despite leading the Formula One world championship, Lewis Hamilton is not overly confident of completing a hat-trick of wins in Hungary.

The McLaren racer took the checkered flag with ease in Britain and Germany to move four points clear in the standings.

But with the tight twists of the Hungaroring presenting a different kind of challenge, the Briton is not predicting another stroll.

"I'm wary about making any strong predictions; yes, we were strong in the last two races, but we encountered difficulties in the two before that, so it's impossible to call it this weekend," said Hamilton.

"I don't go into this weekend surfing any particular wave of confidence: it's such a different type of circuit that it's difficult for anybody to feel certain about their chances.

"All I can say is that our car feels fantastic at the moment and I'm really enjoying driving it."

In stark contrast to Hamilton's ebullience, times are hard for defending world champion Kimi Raikkonen. The Finn has suffered a race-winning drought stretching back to Spain in April, six races ago.

Since then, he has suffered bad luck plus a drop-off in performance of his Ferrari relative to Hamilton's McLaren.

He said: "Hopefully we can get the car back like it was in the previous races and we should be okay. We need to get the package right again and try to win races -- there's a long way to go.

"McLaren were very strong in Hungary last year compared to us, but it is like the Monaco circuit and we were quite strong there this year. So hopefully we can challenge them and try to win."

Somewhere between the emotions of the two is Robert Kubica, whose form earlier in the season saw him take his first F1 pole position and race win.

But since that breakthrough triumph in Canada last month, Kubica has found the going a little harder, with a fifth, a retirement and a seventh place in his last three outings for BMW.

Despite having his status as outsider for the title underlined, the Pole is relying on the familiar to reignite his challenge.

"For sure we can expect a lot of Polish fans in Budapest. The Hungarian Grand Prix is the closest race to my home country, so in some way it is my home race," he said.

"The Hungaroring is the track where I had my first Formula One race in 2006. As a driver you always have a special relationship with the track where you had your first grand prix."
