Lewis Hamilton rounded off his pre-season preparations at Barcelona last week with a spring in his step - as new car updates from his McLaren team left him not only at the top of the timesheet, but confident that he has underneath him an MP4-25 that is good enough to challenge right at the front.

The former world champion was certainly in an upbeat mood as he flew back to McLaren's Woking factory straight after the test to kick start another busy week - this time with off-track media and promotional events.
