Sebastian Vettel finished the final practice session at Austin on top ahead of his teammate Mark Webber. The German lapped his RB9 in 1:36.733 to outpace Webber’s lap time of 1:36.936 by two tenths of a second. And there was more to come from the four time world champion, particularly in sector one, had his race engineer Rocky not told him to ‘minimise’ running for some unknown reason.An interesting thing to note from the session was that drivers were able to better their time on option tyres on their second flying lap.
