The biggest problem was that the F60 was a much more complicated animal than the Force India, with many more electronic tools available to the driver. Learning how to make the best use of them all, while getting on with the basics such as steering the thing and getting it stopped, was a big job.
"It was not easy at all, especially for the first couple of races. I was really struggling on that, losing two or three tenths just on concentration, because I was used to driving just concentrating on driving the car, and now I was switching many buttons.
"It was tougher than I expected. The car was completely different from what I expected to drive, completely different from the Force India. With the KERS system you need to drive differently, and it's not easy because I hadn't done this kind of driving for 15 years.
"You have to concentrate on braking and do different things, especially on the downshift you have to be later on that, because of the KERS, or there is a lot of rear locking. The car was quite inconsistent and the fact that there was no testing at all didn't help me. Starting from the 16th, 17th, the back of the grid, you need to change the strategy and try to overtake. It's not easy. But my pace at Suzuka in the second stint, when I was alone, was exactly the same pace as Kimi. That was very encouraging."
