Vettel made it look easy in India as he clocked up his 11th win of the season --
but in doing so he demonstrated how the fine detail of tyre management has been
the difference at Red Bull this year.
processional race at the new Indian Buddh circuit, strategic thinking and
careful tyre usage played a vital part in some very close battles throughout
the field and resulted in two very different outcomes for Red Bull drivers
Vettel and Mark Webber.
the race, teams were predicting the hard tyre would be slow to warm up and
could be up to two seconds slower than the soft -- pointing towards a strategy
to use the softs for as long as possible without them going off then switch to
the hards late in the race.
enough, that was the tactic employed by all the front-running teams (Lewis
Hamilton and Felipe Massa only took a different approach because of their mid-race
collision) so success or failure came down to how drivers managed their tyres to
get that little extra bit of performance out of them.
case, after doing his usual trick of converting pole into an early race lead
and immediately building a big enough gap to keep out of DRS range from the
second-placed driver, he was in the perfect position to manage the race with
the target of maintaining a gap and staying on slightly fresher tyres than the
Button took second from Webber on lap one then stayed close to Vettel but his
first set of softs lasted one lap less than Vettel's and he had to come in on
lap 18. Vettel's five-second advantage at the time was enough to avoid the
undercut -- where Button would aim to pit first, put in a fast out-lap and take
the lead when Vettel pitted -- and the Red Bull driver came out three seconds
ahead after the opening stops.
second stints both lasted 28 laps and the gap was 4.8 seconds when Button came in for
a second time to change to hard tyres. Vettel pitted one lap later and came out
with a 2.8-second lead, despite the Red Bull being known to suffer more than the
McLaren in warming up the hard tyre. With one lap less running on the hard
tyre, it was then an easy run to the finish for Vettel as Button slowly dropped

difference in the battle for fifth.
Schumacher made an impressive start to jump from 11th to eighth (thanks to
saving his KERS until the back straight) and sat just behind team-mate Nico
Rosberg in the opening stint. He made his first stop one lap later than Rosberg
and his second five laps later, allowing him to set lap times of around 1:28.5
compared to Rosberg's 1:29.5 and jump him at the second stop -- taking fifth
and closing the championship gap between them to just five points with two
races to go.
