Bahrain Friday quotes: Brawn

Rubens Barrichello - 9th: "We had different set-ups running on both cars today to gather as much information as possible and compensate for our lack of testing before the season began. It's very hot here in Bahrain obviously and it was quite difficult to find a good balance today but overall I am comfortable with the work that we have achieved. We are running quite competitively but have further work to do before qualifying tomorrow as other cars around us were also quick."

Ross Brawn: "Whilst the super soft and medium tyre compounds that we are using for the Bahrain Grand Prix weekend are familiar to us, the unique conditions found at this circuit mean that they are working in a very different range. The track is always very dusty at the start of each session and the track temperatures today are by far the highest that we have experienced this year.

"We have therefore focused our efforts on understanding the behaviour of the tyres and are happy with the progress made through the two practice sessions. The intense heat here ensures that on-car temperatures are closely monitored and although we do not have any concerns, it will be a challenging weekend for the drivers."
