Red Bull have the edge on race pace in Singapore

“Not too bad” was Sebastian Vettel’s typically understated assessment of his car’s performance around the streets of Singapore.

But with the fastest time of the day and promising race pace at the end of the second session, Vettel must be eyeing a potential ninth win of the season.

Here’s all the data from the second practice session:

Longest stint comparison

  • Red Bull’s stint pace looks strong, with Ferrari and McLaren not quite able to match it.
  • While Fernando Alonso and Lewis Hamilton maintained a similar pace over their first five laps, Vettel was able to gain lap time as his fuel load came down. All three were on super soft tyres.
  • For a clearer comparison, look at Nico Rosberg’s stint in the Mercedes – he was running a higher fuel level than his team mate and clearly lost pace throughout the stint. “The critical element will be the longevity of the tyres and understanding how to work them to the maximum for as long as possible,” said Ross Brawn.

This chart shows all the drivers’ lap times (in seconds) during their longest unbroken stint:

Ultimate lap times

An ultimate lap is a driver’s fastest three sector times combined.

  • Alonso had a little more time in hand on his fastest run.
  • However both Vettel and Hamilton aborted earlier runs on super soft tyres due to traffic, suggesting they could have gone quicker on fresher tyres.

Complete practice times

  • Despite the gap to his team mate, Mark Webber believes he knows where he can find time on his set-up: “I need to find a bit more pace, but there?s a bit of low hanging fruit which we can grab tonight, which will be good for us. Seb’s going alright, so I just need to find a bit more and get into it tomorrow.”
  • Michael Schumacher said: “the difference between the tyres is quite big”. Drivers were finding improvements of one second per lap or more when switching from the soft to the super soft tyres.
  • Jerome d’Ambrosio and the two HRTs were both outside 107% of Vettel’s time (1’53.820). Liuzzi was furthest away, 1.3 seconds off the notional 107% time. But in the circumstances of qualifying, with the front runners likely to do their times on soft tyres, they have a good chance of getting into the race.
  • The removal of some kerbs around the track may have helped drivers reduce their times. These are likely to be reinstated tomorrow.
  • However not everyone everyone was using the extra space offered by the removal of the kerbs. Hamilton said: “We don?t yet know whether or not the kerbs will be reinstated tonight, so I continued driving as though the kerbs were there. If they?re not replaced, then we should gain an extra couple of tenths by being able to run as wide as some of the others did.”

  1. PJ (@pjtierney) said on 23rd September 2011, 17:46

    Jerome d’Ambrosio and the two Virgins HRTs were both outside 107% of Vettel’s time (1’53.820). Liuzzi was furthest away, 1.3 seconds off the notional 107% time.

    Minor error in an otherwise awesome article :)

  2. I’d have thought that this track would be all about max downforce, yet once again FI are at the top of the speed times and are looking none to shabby for a midfield team overall.

  3. Vettel looks like he’s going to annihilate all this weekend, Webber is nowhere by comparison.

  4. The “ultimate lap times” are most informative, showing apparently Vettel and Alonso in a class of their own. But has anyone had the time to compare these numbers with the “quali” times afterwards? It would be interesting to know which drivers have the skill to approach their “ultimate” on a single lap that really counts.

    • raymondu999 (@raymondu999) said on 24th September 2011, 1:46

      That’s what the “Deficit to best” stands for. It’s basically their current lap time as on the P2 scoreboards, minus their ultimate lap. These would all be from their quali simulations on the supersofts; as all of them set green or purple sectors on those tyres

    Interesting to see what McLaren is doing in practice…

    It appears (from the practice pics at least, since I havent had a chance to watch the practice sessions yet) that Lewis is running the small-flap wing that they had on at Spa and Monza, and Jenson is running the large-flap wing that they’ve used at every other race.

    Being that the small-flap wing seems to offer better qualifying pace for them (due to more effective DRS), and the large-flap wing has seemed to offer better race pace, my guess is that they are trying to figure out if they can afford to sacrifice race pace for better qualifying position. This is somewhat supported by Lewis’ trap speed being nearly 4km/h faster than Jenson’s (although that isnt taking into account the multitude of other variables that could contribute to this).

    Just speculation on my part of course, but I love when we get any insight into how teams run their practice strategies!

    • bosyber (@bosyber) said on 23rd September 2011, 20:33

      Interesting observation!

      I also think it will be fascinating to see how the midfield fight – here Mercedes, FI, Renault, Sauber (to some extent) will turn out. Even Williams seems to be in it somewhat, if they can get through Q2, that is. STR didn’t do a long stint, due to that shunt by Buemi and a problem on Alguesuari’s car so they are harder to judge, but should be about there too.

    • After looking at the pictures I think you are absolutely right. Lewis rear wing clearly has a much smaller flap compared to the one on Jenson’s car.

    • raymondu999 (@raymondu999) said on 24th September 2011, 1:47

      I would think it’s the reverse; if they could sacrifice quali position for a bit more race pace

  6. unoccprost said on 24th September 2011, 4:46

    Vettel vs Alonso.

    Alonso seems able to match.

  7. AndrewTanner (@andrewtanner) said on 24th September 2011, 11:16

    So that’s pretty much both sessions where Vettel has had almost 1s his team mate. Crushing stuff there.
