Williams duo Pastor Maldonado and Bruno Senna are confident that improvements to their car will lead them to success at the British Grand Prix.

The team will be adding improvements to their car this weekend ahead of the event at Silverstone as they look to add to Maldonado's victory in the Spanish Grand Prix from earlier this year.

Williams are also encouraged by Pirelli's tyre selection of the hard and soft compounds being the same choice that was used for the Barcelona race, and both drivers are optimistic going into the circuit.

"I think the track will suit our car because it's similar to Barcelona and it's also very fun to drive with sections like Maggots and Becketts which really test you as a driver," said Maldonado.

The pace of the car in Valencia was very promising and we have a number of updates expected for this race as well so hopefully we can give the home fans a good result."

Teammate Senna is also happy with the changes to his car, adding: "Silverstone is one of my favourite tracks because it's high speed and flows really well.

"Our car has good pace at the high down force tracks and is good on high speed corners as well so it should suit Silverstone."

The British Grand Prix takes place at Silverstone on Sunday.
