SEPANG, Malaysia - Whether Brawn GP can sustain its sensational start to the season will be the key focus of the Malaysian Grand Prix on Sunday, along with the fate of heavyweights McLaren and Ferrari.
Jenson Button and Rubens Barrichello handed the rookie team a 1-2 finish in Melbourne last weekend in the team's maiden race, upsetting the established order.
New rules that have allowed the return of slick tyres and an increase in the aerodynamic downforce to help cars grip the track worked in Brawn's favour, and set the stage for an intriguing race around the 56-lap Sepang circuit.
Ross Brawn, who bought the team from Honda Racing in March, is confident their run will continue. But Britain's Button is not getting carried away, warning that other teams are hot on their heels with encouraging competitive signs from Toyota, Williams, Red Bull and BMW Sauber.
"I have a feeling that other teams are going to be on us very quickly and when we get to a different type of circuit, maybe in Malaysia, some other cars which weren't so competitive in Melbourne will be," Button said.
He expects those that are using the new Kinetic Energy Recovery System, which recovers the energy generated by the car's braking process for extra power, will do better at Sepang.
The intense heat and humidity will also be a factor. - Sapa-AFP
