Jenson Button believes McLaren can look forward to a strong showing in Hungary thanks to their latest batch of updates.
McLaren introduced new sidepods and rear wing as well as other less noticeable updates at the previous race in Germany which Button finished in second place.
The Woking team carried that pace through to Friday's first practice in Hungary with Lewis Hamilton finishing quickest ahead of his team-mate
"I feel the parts we put on the car work for us and I think maybe they're getting the tyres to work more in the dry conditions," Button said.
"The dry is much better. There's still some areas where I feel we're weak compared to the Ferrari and the Red Bull.
"I got to look at their cars quite a lot at Hockenheim, but there are areas where we're stronger also.
"In the wet it's still tough, because we struggle to get temperature into the tyres.
"If the conditions are slightly wrong, slightly too wet for that tyre, it doesn't work and we're four seconds off the pace like we were at Hockenheim."
