Lewis Hamilton enjoyed a positive end to testing in Barcelona after completing the largest number of laps in a single day for McLaren 's new MP4-26.
The Briton managed 107 laps of the Catalunya circuit en-route to the fifth quickest time as he worked through a lengthy programme focused on tyre development.
That meant Hamilton wasn't focused on chasing lap times but was instead keen to see how the Pirelli tyres would work throughout a race stint.
“It was very encouraging to log over 100 laps with MP4-26 today – an impressive conclusion to our four days in Barcelona,” McLaren test team manager Indy Lall said.
“We're still working through a very lengthy development programme – today wasn't about pure performance, it was about conducting a disciplined series of long-runs – but it's been a positive end to our test here.”
