McLaren rookie Kevin Magnussen admits he is feeling a few nerves as he prepares for next week's first test.
The 21-year-old Dane has joined Jenson Button at McLaren for this year's Championship, the first rookie to climb into a McLaren since Lewis Hamilton in 2007.
But with his arrival in F1 coinciding with a host of new regulations, Magnussen believes he is now more nervous than the rest of the field.
"Naturally, sure," he said when asked if there was a 'sense of nervousness going into the first test.'
"You never reach a point where you feel completely 'ready' - there's always more you can do. But I think every team and driver is going to be feeling uncertain going into the pre-season."
The 2013 Formula Renault 3.5 Series Champion has already done some work towards being prepared for the upcoming season having spent time at McLaren getting to know the systems he will be working with.
"I'm just working hard to make sure that I'm as ready as I realistically can be - so I've learned the cockpit systems inside-out, I've been in the gym at the MTC every day, and I've worked hard with my engineers to understand just what to expect from this new formula.
"In a way, the regulation changes makes things a little easier: at that first test in Jerez, everybody will be easing themselves into something new, rather than just getting in the car and driving away, so I'll really be no different from any other driver.
"It'll be how we react during the season that will define how successful we are. I know the engineers are working on new things all the time, but I think there's still plenty of scope to move forward.
"I don't think you'll get a definitive read on who's competitive and who's not until at least the Bahrain tests - maybe even later."
