Canadian GP Press conference

Lewis HAMILTON (McLaren), Pastor MALDONADO (Williams), Sergio PÉREZ (Sauber), Vitaly PETROV (Renault), Adrian SUTIL (Force India).
Q: Adrian, talk about this circuit as you have said it is one of your favourites.
Adrian SUTIL: Yeah, this is a very nice circuit. I like it here. I like the atmosphere here and it is a kind of street circuit. We have long straights here, some chicanes and there is always something happening in the race. It is usually good to overtake but also Montreal as a city is a nice place so I really enjoy the whole weekend.

Q: In terms of the car what sort of modifications have the team brought here for you to address the special qualities of this circuit?
AS: We are still trying to improve our upgrade package that we took to Barcelona. It is not easy to make it work, the blown diffuser, at the moment, the way it should be. But we are working on it. In Monaco I think we ran it for the first time in the race. We are not sure if it really was a big advantage but I am sure it was a little. But there is still more to come. We need now just time on the circuit to understand a lot of things and we also have some other updates on the car, not only the diffuser, especially for this race here. It should be good for us. We have a big straight-line speed. It is a very fast car on the straights. This circuit has fast straights and a few slow speed chicanes and hairpins so it is not such an aerodynamic circuit here.

Perez shows Sauber potential

Sergio Perez gave Sauber plenty to smile about over lunch on Thursday by setting the fastest time on the third morning of testing at Barcelona.

Late on Tuesday Perez lit up the timing screens with an unprecedented lap, but it turned out he had skipped the final chicane in order to avoid traffic. However, the lap on Thursday morning was genuine and set over a single flying lap, most likely on low fuel. The time was the best of the week, pipping the one set by Sebastian Vettel in the Red Bull on a seven lap run on Wednesday.

The track temperature certainly played its part, with the surface of the circuit peaking over 30C before lunch. It was the first day of the test so far with completely blue skies, something McLaren

Sauber sponsor Slim tops world rich list

Business magazine Forbes has named Sauber sponsor Carlos Slim the richest man on earth. 71-year-old Slim, the Mexican telecoms magnate who is backing the Swiss team and its rookie Sergio Perez this year through his company Telmex and its subsidiaries, grew his fortune over the past year by more than $20 billion to $74bn, the magazine said.

F1's chief executive and 'supremo' Bernie Ecclestone is 254th on the world rich list with $4.2bn, and Virgin figurehead Sir Richard Branson is reportedly equally rich.

Slightly wealthier is Red Bull Racing and Toro Rosso owner Dietrich Mateschitz with $5 billion, while Force India's Vijay Mallya is ranked 879th on the billionaire's list with $1.4bn.
