Barcelona F1 test: Alonso sets early day-three pace

Fernando Alonso led the way on Thursday morning in Barcelona Formula 1 winter testing

The Ferrari was quickest for the majority of the four-hour session.

Alonso and Williams's Pastor Maldonado swapped the top spot for a spell as both did short runs on soft tyres, but Alonso then started edging clear with repeated small improvements.

Nico Hulkenberg ultimately got closest for Sauber, lapping 0.286s adrift of Alonso on a quick soft-tyre run of his own.

Romain Grosjean took the Lotus over from Kimi Raikkonen and completed the top three.

Mercedes made a slow start to the morning, focusing on data-gathering. That meant a long garage sojourn while the various measuring appendages were removed, after which Nico Rosberg got up to fourth.

Following his early dice with Alonso, Maldonado concentrated on much longer runs, completing an ample 79 laps before lunch.

He will hand over to team-mate Valtteri Bottas for the remainder of the day.

Jenson Button completed the top six for McLaren.

Adrian Sutil's return with Force India gathered plenty of interest. The German was fully engaged with the team's development programme, starting off with aerodynamic tests before lapping a second off the pace in seventh.

Mark Webber was back in eighth at the end of a low-key morning for Red Bull.

The session ran smoothly, with no red flag interruptions.
