Red Bull Racing's Mark Webber has accused some of his rivals of 'sandbagging' following practice today for Sunday's F1 2010 British Grand Prix at Silverstone.

Webber, who was quickest overall - on a 1 minute 31.234 seconds, 0.392 seconds up on Fernando Alonso's Ferrari, added though that he was pleased with his day's work.

Indeed while he had an electrical problem, that meant he missed the final 15 minutes of FP2, the Aussie was on good form and seemingly had no ill-effects following that monster crash at the European GP two weeks ago.

"A pretty good day apart from the electrical problem at the end, which was a shame - we lost a few laps," Webber noted.

"The car seems to be going pretty well here otherwise - I think a few of the other teams were sandbagging a bit, but we're happy with our programme and looking forward to qualifying.

"The new section of the track is pretty difficult, but they got it right I think - it's a good challenge for the drivers."

Team-mate Sebastian Vettel meanwhile was also right on the pace and having been quickest this morning in FP1, he was third fastest this afternoon, his best a 1m 31.875s, 0.641 seconds slower than Webber.

Vettel, like Webber, was pretty happy with his Renault-powered RB6 and he too gave the revised Silverstone the big thumbs up.

"The sessions were okay today - in the afternoon I had a bit of a spin and flat-spotted a set of hard tyres. We also had a problem with the brake pedal, but nothing big," Vettel noted. "The pace of the car was good.

"The new section of the track is quite low speed, but it's not as slow as we expected and doesn't kill the rhythm. It adds something new and makes if more of a challenge. The track here is magnificent; it's good fun, so I'm looking forward to tomorrow."
