Play F1 | Grosjean: You cannot drive most of the grand prix at 90 per cent as before, sometimes now it is only 30 per cent

Although clearly not happy with the frustrations of getting his race car where he wants it to be in the shortest possible time, Romain Grosjean is quick to see the positives and potential as Lotus F1 Team heads to the second race of the 2014 season in Sepang, Malaysia, this weekend.

How different is the driving experience in a grand prix now after the technical changes?
Grosjean: It is not quite as pleasant as before to be honest. There is a lot of energy recovery to deal with and optimise. You cannot drive most of the grand prix at 90 per cent as before, sometimes now it is only 30 per cent. We just have to get used to it. When you win you love it and when you retire [from a race], you don’t. At the moment it feels a little frustrating as a driver but these are the rules, we will adapt and make the best of them.

What will be the main challenges at Sepang?
Grosjean: The first challenge in Malaysia will be the heat, humidity and usual rain storms at 4pm!
