Although expecting a "real challenge" at the Sepang circuit, Felipe Massa and Valtteri Bottas head to Malaysia targetting points... Felipe Massa: Malaysia is a nice place to race, it's a hot and humid race which makes it a physically tough one for the drivers. The heat also has a big effect on the tyres and how quickly degradation happens. These extreme temperatures means Malaysia is less like any other circuit we will race at. When you go to Malaysia you can never count out the weather either, there is always the chance of rain, its heavy rain too, and this can happen at the end of nearly every day. All of these factors mean the race is always exciting from a fans point of view but these changes are tough for the drivers. I'm looking forward to having a good race there. Valtteri Bottas: Malaysia will be a real challenge for us, but also something the other teams will have to deal with too. Cooling will be a major factor as the temperatures are so high, there is also still a lot to learn about the new power units, so this heat adds to this learning curve. It could be the hottest race this season and having it at the start of the season when people are trying to develop what they have isn't the easiest of tasks. Physically for the drivers it isn't easy; we have to work hard in the off-season so we are ready for times like this. The track itself is very nice; it has some great high speed sections which are my favourite parts of the circuit.
