Whitmarsh: Red Bull have yet to show their hand

It will be hot in Malaysia - and not just where the temperature is concerned, the action out on the track will be 'hot' too. McLaren team boss Martin Whitmarsh is certain of that: "Sepang is a challenging high-speed circuit that will show which cars have the best grip and downforce. It will be very hard on cooling systems and impinge a great deal on tyre management." Pirelli reckon that drivers will make an average of four pit stops each.
