F1 : Bahrain GP Pit Stop Analysis

by on April 23, 2013

Here is a quick chart on the pit stops in Bahrain that I compiled. It shows who pitted when and what compound was fitted.  If nothing else, it shows the overall consistency of compound life.  It also gives us a brief overview of who was more gentle or harsh on their tyres on this particular circuit.

As we can see, Kimi Raikkonen and Paul Di Resta were able to get away with running a two stop strategy.  This makes a strong argument supporting that the Pirelli tyres may not be as sinister as they are being made out to be.  Given the right setup, it is possible to make better use of the P-Zeros.

I also did a quick analysis of pit stop delta timing between race winner SebastianVettel and Fernando Alonso.  Vettel had a total pit stop delta time of 1:04.856  vs Alonso’s 1:26.803.  This is a difference of 21.947 seconds.  Alonso finished the race in 8th position, 37.5 seconds behind Vettel.

If we were to assume that Alonso would not have had to make an additional stop for his malfunctioning DRS, (providing all other circumstances being equal) we can assume that Alonso would have been (approx.) 15.553 seconds behind Vettel.  That gap would have put the Spaniard six seconds behind Räikkönen and four seconds ahead of Grosjean.  The issue Alonso experienced with his DRS may have well cost him a podium finish in Bahrain.

Of course this is all theoretical.  There is no way to know what else may have happened. I wouldn’t know how to calculate how much time Alonso lost running the better part of two laps with his DRS flap wide open. I don’t know if Alonso might have been able to run in clear air or if he would have spent more or less time in traffic.  His battles with Perez and Button may have cost him time as well.

Could he have challenged Räikkönen or Vettel? I suppose we’ll never know.
