Italian GP: Vettel flies in second Monza practice

The world champion was barely headed during the session, pulling clear of his rivals with an early 1m24.7s lap before improving to his final benchmark 1m24.453s after half an hour.

Vettel's long-run times also proved comfortably quicker than the pack in the latter half of the session.

Underlining Red Bull's ominous form, Mark Webber completed a one-two in the second car.

The times were much closer in Webber's region, though, as Lotus pair Kimi Raikkonen and Romain Grosjean were equal on 1m25.116s just 0.040s behind.

Their identical times came despite Raikkonen using the upgraded long-wheelbase version of the car while Grosjean remained in the standard specification Lotus.

Fernando Alonso was fifth in the best of the Ferraris. Like Grosjean, the Spaniard had a brief trip through the gravel during the session.

Felipe Massa put the second Ferrari eighth behind Mercedes duo Lewis Hamilton and Nico Rosberg, but had to park in the pits early with a gearbox issue.

The McLarens of Jenson Button and Sergio Perez filled the final top-10 places.
