Alonso, Raikkonen, Button missing from Spanish line-up
Formula One testing resumed on Tuesday, with the bulk of the teams in action at Barcelonas Circuit de Catalunya. This weeks test is the first of three major sessions scheduled to take place in Spain ahead of the Christmas break.
Ten of the 11 teams are expected to run during the course of this week, all of them on Bridgestone rubber ahead of the move to a single tyre supplier for 2007. For those teams who competed on Michelins this season, the focus of the test will be adapting their cars set-up to their new Japanese tyres.
Notable absentees in Barcelona will be world champion Fernando Alonso and Kimi Raikkonen. Neither is expected to be released from their respective Renault and McLaren contracts until the end of 2006, meaning they will have to wait until the New Year to begin testing for new teams McLaren and Ferrari.
No such problems for Mark Webber, who made his testing debut for new team Red Bull on Tuesday morning, after getting clearance from 2006 employer Williams. Webber is no stranger to the team, having driven for them during their previous incarnation as Jaguar.
Another man missing from this weeks line-up - though for very different reasons to Alonso and Raikkonen - is Hondas Jenson Button. The British driver managed to crack two of his ribs in a recent karting accident and has opted to sit out the test to avoid aggravating the injury.
Honda are running their car with a black livery in Spain, and do not be surprised if other teams are sporting new graphics this week in light of the ban on tobacco advertising from 2007.
