McLaren-Mercedes

You have to go all the way back to 1998 for McLaren's last constructors' championship and that hurts badly at Woking, even though they have taken a few drivers' crowns during the interim. Although determined to make amends for last year, when it spent much of the season fractionally off the pace of Red Bull, the team endured a difficult birth of its innovatively packaged MP4-26, which has been unreliable and off the pace of Red Bull's RB7. But as it has proved on many occasions - most recently in 2009 - McLaren has the development might to turn an underperforming car around.
