F1 testing: Lewis Hamilton sets the pace for Mercedes

Mercedes driver Lewis Hamilton sets the pace on the penultimate day of pre-season Formula 1 testing in Barcelona.

The world champion describes the team's performance as "exceptional" after underlining the impression that Mercedes have a clear advantage by beating Williams's Felipe Massa despite using slower tyres.

Reserve McLaren driver Kevin Magnussen, standing in for Fernando Alonso as the Spaniard recovers from concussion, managed only 38 laps before an oil leak ended the team's day shortly after lunch.
