Lewis Hamilton admits that McLaren has 'a lot of work to do' ahead of the opening round of the F1 season in Australia after the final day of pre-season testing was effectively washed out in Barcelona.
Heavy rain prevented the four teams still present at Catalunya from carrying out any meaningful running on Saturday, with Hamilton, Pastor Maldonado and Nico Rosberg the only three drivers to post a timed lap.
Hamilton was the only man to set a lap time during the morning and ultimately ended the day third quickest – admitting afterwards that conditions had been too risky to try and complete any longer runs on track.
With the MP4-26 having failed to deliver so far, poor conditions and limited running was the last thing McLaren needed on its final day of running and Hamilton admitted there was still work to do ahead of the Albert Park race, although a number of upgrades are still coming ahead of a season the Briton believes will be wide open.
"We tested a couple of things during some shorter runs, but it was very dangerous out there: very slippery and lots of aquaplaning,” he said. “This definitely isn't normal Spanish weather! We learnt a bit about the Pirelli Intermediates and Extremes, but there was so much aquaplaning that it was a bit too risky to do longer runs.
"As for the world championship, I'm excited - we've got a long season ahead of us. We've got a lot of work to do, but we have more updates coming for Melbourne.
"The championship is open, and we don't know what to expect. Our whole team will be pushing very, very hard."
