Perez scored three podiums in 2012 to grab the attention of McLaren as they sought a replacement for Mercedes-bound Lewis Hamilton.
"Of course, I am fully aware of the steep slope ahead of me: it has already been an intense couple of weeks, getting to grips with a new team, meeting my engineers and mechanics, learning new ways of working and, of course, learning all about a brand new car – something I’ll need to do with just six days of on-track testing. It’s a big challenge," said the Mexican.
"But it’s definitely going to be an exciting few weeks: although I’ve been racing in Formula 1 for the past two seasons, every racing car is different and it always takes a little time to adjust. Firstly, I’ll need to understand the different characteristics of the car; secondly, I’ll learn how to best work with my engineers to make the car suit my personal driving style. It’s going to be an interesting and exciting journey."
"But I’m more prepared than I’ve ever been for the start of a new season. I feel extremely fit, focused and refreshed – there’s still a lot to do, but my aims are to feel confident, comfortable and ready to race by the time I land in Australia in just a few weeks’ time."
