Mark Webber remained on top of the pile during second free practice for the Spanish Grand Prix as times tumbled at Catalunya.

The Red Bull driver made the most of a switch to the softer Pirelli tyres to vault to the top of the times mid-way through the session with team-mate Sebastian Vettel also setting a series of impressive times as the pair lapped noticeably quicker than the remainder of the field.

However, Webber's benchmark time of 1min 22.470secs was almost beaten by the McLaren of Lewis Hamilton as the Briton was able to split the Red Bulls on the times once he too had switched over to the softer tyres.

Hamilton would eventually end the session second to Webber but was only 0.039secs down on the Australian, with Vettel three-tenths of a second off the pace in third.

Jenson Button was fourth quickest in the second McLaren and the final driver within a second of the quickest time while Fernando Alonso and Nico Rosberg completed the top six.

Michael Schumacher, Felipe Massa, Kamui Kobayashi and Nick Heidfeld completed the top ten.

Massa was one of the drivers to take a trip off track during the session as he ran through the gravel, as did the Hispania of Narain Karthikeyan. Both however were able to stay out of the barriers and rejoin.

Down towards the rear of the field, there was encouragement for Lotus - and disappointment for Force India - after Heikki Kovalainen was able to outpace Adrian Sutil. Kovalainen did have a small scare during the session however when he came across the slow Williams of Pastor Maldonado while on a quick lap, with the Venezuelan appearing to get in the way of the Lotus despite trying to stay offline.
