The Lewis Hamilton-Jenson Button partnership will not just be the focus of attention for British F1 fans this season: it’s the first time two world champions have shared a team in 21 years.
Testing restrictions mean the pair are yet to appear together in action but McLaren recently put their two world champions on track for a photo shoot in their MP4-25s.
This is the first time two former champions have shared a team since Ayrton Senna and Alain Prost lined up at McLaren in 1989.
As the reigning champion, Button carries the number one and Hamilton has number two as he did in his debut season alongside Fernando Alonso in 2007.
Here are the first pictures of the pair on track together. When it comes to driving their cars in anger it remains to be seen whether they will be racing at the front or back of the pack in 2010.
