Mechanical and aero set-up work for Button

F1 Test, Barcelona, Circuit de Catalunya

First day of the final test of the winter. 2009 Champion Jenson Button kicked off running in Barcelona this morning for the McLaren Mercedes F1 Team, concentrating primarily on mechanical and aerodynamic set-up work.

Despite not setting any headline laptimes, the team declared itself pleased with progress, gaining a greater understanding of the behaviour of the Bridgestone tyre over a long run.

For tomorrow, Lewis takes to the circuit. He continues today’s programme, developing set-up and working with the tyres.

Jenson returns to the cockpit on Saturday before Lewis concludes the running on Sunday.
