McLaren plans further upgrades for the Hungarian Grand Prix

A major package of updates, which included allowed McLaren to return to race-winning contention in the German Grand Prix.

It is hoped that further aerodynamic upgrades at the Hungaroring will build on that progress after team principal Martin Whitmarsh stressed the importance of ongoing development work.

"There are some more updates for Hungary," said sporting director Sam Michael. "We will definitely be bringing parts there and then to Spa.

"For Monza, we will probably just have Monza-specific parts and then [another upgrade] at Singapore. That's where we are at.

"Without question, we made a big step at Hockenheim. We saw that in FP1 and FP3 in the dry and if we can get on top of our performance in the wet then we will have the complete article.

"We had competitive race pace and super-competitive qualifying pace if it was going to be dry. I'm sure that we can be really competitive [in Hungary]."

Michael has no doubts that McLaren had the quickest car in Germany and that Jenson Button would likely have won had he qualified better

But for the wet conditions during Q3, in which both Button and Lewis Hamilton struggled for tyre temperature, he believes that a win was on the cards.

"If we had qualified better, we wouldn't have used up so much energy, particularly in the tyres, to get back to where [Fernando] Alonso and [Sebastian] Vettel were. We would have been able to use our pace against them.

"If we had qualified around them and then we would not have been held up by [Michael] Schumacher and [Nico] Hulkenberg for a few laps at the beginning, which costs us the time. If we were racing next to them, there's no question we would have had the ability to race for the win."

Michael also admitted that there might not be any quick fix for McLaren's problems with tyre temperature in wet conditions, although much depends on the track characteristics.

At Silverstone, both drivers struggled on intermediate rubber, while at Hockenheim the cars were quick on those tyres, but uncompetitive on wets.

"Getting on top of wet problems is quite difficult, especially when you are inconsistent," he said. "You don't replicate the conditions anywhere.

"Then there are other factors such as load at Spa. You could have a warm-up problem at Spa, but it's such a high-load track that we could probably overcome it anyway because of the high-speed corners and long out laps."
