Jenson Button believes his superior Formula One experience will count for nothing when he takes to the test track with new Vodafone McLaren Mercedes team-mate Sergio Perez for the first time.
The 2009 World Champion from Frome joined Mexican Perez, known by nickname Checo, in unveiling the new MP4-28 at the team's Woking base.
Former Sauber man Perez replaces Lewis Hamilton, who ended a 14-year association with McLaren in the winter to join Mercedes AMG.
Button, 33, said the ten-year age gap between himself and Perez, and his career that has seen him win 999 points, gives him on obvious advantage.
However, Button added that both drivers will arrive in Barcelona next week with the same limited knowledge about how their new car will behave on the track.
"I'm obviously the more experienced driver in the team and obviously experienced in the sport," said Button after arriving at the launch in the new McLaren P1 road car that ended a procession of the race team's most historic vehicles.
"We have 12 days of testing before the first race and I do six and Checo does six. The feedback from both of us is very important, neither of us can do it on their own.
"Checo will listen in to me and I will be listening in to him. I'm sure we will be listening in to each other and understanding where the car is going.
"Even though I come to the season with more experience, in terms of the car that means nothing."
And despite a move at South Korea that led to Button's race retirement and an apology from Perez, the keen triathlete believes his latest team-mate showed plenty of encouragement last year.
Button said: "In a very difficult race in Malaysia he had a fantastic result, finishing second, so close to the victory and I'm sure he thinks about that moment even now.
"Obviously at Monza I wasn't in the race at the end so I was able to watch Checo come through the field and chase down Lewis (Hamilton) at the end. They are two very good races he should be proud of.
"The consistency through the year was good as were the results that didn't come but should have done. Working with a top team that has achieved so much really will bring the best out of you."
