Hungary Friday quotes: Honda

"The changes ensured that the car was a lot more responsive this afternoon and an improvement over how it has felt for much of this season. Our long run pace is looking okay but we have further work to do over one lap as the balance is not quite there yet."

Rubens Barrichello - 19th: "It has been a challenging day today, which we expected as we continue the set-up work with our revised rear suspension and new aero parts. Once the track had improved this morning, we worked on getting the right balance on the car and conditioning the tyres.

"Unfortunately we struggled with understeer and we need to look at the data closely this evening to confirm our direction before qualifying as the lack of overtaking opportunities here makes it important to get a good grid slot."

Steve Clark - Head of Race & Test Engineering: "This is always a demanding circuit for the brakes and engine due to the high ambient temperatures and low average speed. We also need to be mindful of the fact that we are expecting an equally hot weekend in Valencia in three weeks time, therefore engine management will be particularly important here.

"The nature of this circuit calls for the Bridgestone soft and super soft tyre compounds with which we will need to maintain a balance to prevent graining and overheating. Beyond that the heat will make this a tough race for the drivers, however ours are well prepared for these conditions.

"We have introduced some significant mechanical developments to the car this weekend as well as the final stage of our mid-season aerodynamic upgrade. Whilst we have a tangible improvement in terms of stability and improved grip in the high-speed corners, the developments have produced some significantly different characteristics and we are still developing the set-up of the car around these. We have some way to go to achieve the optimum balance and this is reflected in the timesheets today."
