"Austria exposed the biggest vulnerability of our car and it meant we couldn't challenge for the win at any point of the weekend.
"We've been working on our cooling for a while, but the combination of high temperatures and altitude in Spielberg ultimately meant that we had to do too much temperature management to be competitive.
"We will continue to work on this to have a better fighting chance at future races in the heat.
"Fortunately, the English summer is known for more moderate temperatures, so cooling should not be a major issue for us in Silverstone - although we've learned in the past that the weather at the British GP can be highly changeable.
"Silverstone is a sensational track and the sweeping corners demand a lot from the drivers and the car. We've had some of our best performances this year on tracks with a wide range of corner speeds, so on paper we should be in relatively good form.
