Jenson Button says that no team can feel secure that they have mastered the 2014 regulations.
Formula 1 has undergone some of the biggest technical changes in decades for the 2014 season.
Button reckons that the complexities of the rule changes means that no-one can be confident approaching the new campaign.
"I think every single person in Formula 1 is sitting on the edge of the unknown," he said.
"That’s both exciting and unsettling in equal measure. There will be lots of things going through my mind when I settle myself into the cockpit for the first time in Jerez next week, but, above all else, what I’ll be looking for is that simple, positive feeling you get from knowing that the car beneath you is a solid platform; one you can work with, and one you can develop throughout the season.
Button will sample the McLaren MP4-29 at the Spanish circuit next week but does not believe that the first test will provide conclusive answers.
"I don’t think anybody will be coming out of this first test feeling certain that they’ve cracked this new formula."
"I think it’ll be more of a case of slowly peeling away successive layers as the engineers and designers gather more information and gain an understanding of how the cars and power-units are behaving; and we’ll see that being gradually refined throughout the forthcoming tests and into the opening races."
"I think this formula is too big, and too complex, for a single team to feel secure about getting everything right and quickly establishing an advantage. It’s about diligently chipping away at it that we’ll get there."
Button says that while McLaren must improve on a disappointing 2013 season, they simply need to approach the opening races feeling comfortable with the MP4-29.
"Our aim must be to have a smooth and productive winter; I’m very keen to learn all about the new formula and our new car, and I want us to be in a position where we head to the opening flyaways feeling comfortable with our package, yet still ready to absorb and learn more as we go."
"I don’t think anybody’s anticipating the next few months to be easy – I can’t imagine anybody in the pitlane would admit to that – but our aim must be to make progress all the time, and to learn positively as we go."
