Rubens Barrichello made an excellent start to take the lead of the Spanish Grand Prix from third on the grid.
With more fuel on board than second-placed Jenson Button, and overtaking very difficult at the Circuit de Catalunya, he should have been very hard to beat.
But a strange strategy call left Barrichello second behind Button at the chequered flag. Did his team call it wrong – or was he put on an inferior strategy because Brawn has decided to back Button for the championship?
After the first round of pit stops we heard a clip of Brawn’s radio broadcast where Barrichello was told that Button had switched “to plan A.” It soon became clear Barrichello was running a three-stop strategy, while Button would only be stopping twice.
After the race Ross Brawn said: “three stops was always going to be the quickest strategy particularly with [the hard tyres] being so slow”
Brawn also said that Barrichello had problems on his third set of tyres. Barrichello said the same in the press conference (although he referred to his second set of tyres, it’s likely he meant the third). The lap times support this explanation:
After the race, Barrichello said: “Before the race the agreement was that both the cars would be doing three stops.”
According to Brawn, Button was switched onto a two-stop strategy “to avoid leaving him behind Rosberg”. This also makes sense: Rosberg was 18.646s behind Button when Button made his first pit stop on lap 17, so whatever happened Button was going to come out behind the Williams. Putting him on a two-stop strategy ensured Rosberg did not hold him up.
Barrichello stuck to his three-stop strategy and came out narrowly ahead of Rosberg. But Button was able to stay close enough to Barrichello during his second stint to move ahead of his team mate after the final pit stops.
What I don’t understand about Brawn’s version of events is this: Having seen Button change onto a different strategy, why did Barrichello’s crew not change his strategy to cover Button’s, when that was the only car likely to take the win off them?
A strategy with fewer stops is always the safest options. It makes the car less vulnerable to a safety car period. It is highly unusual to see a driver leading a race gamble it on a strategy that involves relinquishing track position.
Also, few other teams reached the conclusion that the three stop-strategy was superior. The only other driver to stop three times was Williams’ Kazuki Nakajima – and he had made an early pit stop during the first safety car period.
And if the purpose of the three-stop strategy was to reduce the amount of time spent on the unfavourable hard tyre, why did Barrichello make his final pit stop only two laps after Button?
Going into today’s race Barrichello was 12 points behind Button with 130 still to be won. Would Brawn really decide to sacrifice Barrichello’s season to Button’s at this early stage? Many people would suspect that they would – and point to Brawn’s treatment of Barrichello at Ferrari in the 2002 Austrian Grand Prix as a perfect example.
A poll during the live blog showed 69% of people believed Brawn had deliberately put Barrichello on an inferior strategy. I’m not convinced yet – after all the called Barrichello’s strategy wrong at Bahrain with no obvious ulterior motive. What do you think?
How do you explain Barrichello's strategy?
- The team wanted Button to win (53%)
- The team made a mistake / Barrichello was slow (47%)
