In just three years the Singapore Grand Prix, F1’s only night race, has established itself alongside Monaco as one of the two most important races on the calendar for the sport, the teams and sponsors.
But the race on the Marina Bay Circuit is also one of the longest and toughest of the year for cars and drivers. The race can last up to two hours and with high temperatures, humidity and constant braking and turning, it is a real marathon.
Strategy wise it was a three stop race last season and this year Pirelli is again bringing the soft and supersoft tyres. However we have seen a trend this year of races taking one less stop than in 2011, so two stops will probably be the most common strategy.
Last year there was a problem with tyres getting cut by bolts set into the plastic kerbs, this will have been remedied for this year.
As the track is at sea level, the air pressure is higher, the air is more dense and this means that the fuel consumption is higher. The stop and start nature of the track further adds to this. So the cars start heavier than at many places with around 155 kilos of fuel on board -10 kg more than the average. This adds to the punishment of the tyres in the early stages of the race.
The 2012 FORMULA 1 SINGTEL SINGAPORE GRAND PRIX is the 14th round of the 2012 FIA F1 World Championship.
McLaren has won the last three Grands Prix from pole position, making a total of five wins from 13 races for the team this season. Ferrari were strong in Monza, but that is a high downforce circuit so the carry-over to Singapore cannot be guaranteed. Red Bull has been struggling for qualifying pace lately and must urgently address this to revive the drivers’ championship campaign.
Lotus were strong in Monaco, Hungary and Valencia, which is normally a good indicator for Singapore and were good on the supersofts on Montreal, as were Sauber, with Perez taking a podium.
As far as drivers’ and teams’ form at Singapore is concerned; Alonso won the race in 2008 with Renault and 2010 with Ferrari, Lewis Hamilton won the 2009 edition for McLaren and Sebastian Vettel won last year.
The weather forecast for the weekend is for high temperatures, around 31 degrees, with little chance of rain forecast. However in four previous events rain hasn’t affected the race, so we must be due a wet race soon, given the nature of the weather in Singapore.
Pirelli tyre choice for Singapore: Soft (yellow markings) and supersoft (red markings). This combination was seen in Monaco and Montreal.
In Singapore the great challenge is to look after the rear tyres, which get damaged by the constant stopping and starting at the circuit’s 23 corners. Pirelli found in its first year that it’s quite an aggressive track and the risk here is overheating the tyres, leading to the thermal degradation we saw in many of the early races this season.
It is one of the hardest races of the season for the brakes, not because of big stops from high to low speeds, but because of the frequent brake use and no straights to cool the brakes. This places an extra strain on the tyres as the red hot brakes inside the wheels cook the tyres from the inside, so tyre management is difficult.
The supersoft is expected to be around 0.8 secs faster on a lap than the soft tyre and is more heat resistant with a higher working temperature range. Last year teams tended to do more stints on the supersoft than the soft, although Ferrari favoured the soft tyre.
Last year the top four finishers made three stops, with first and last stints on supersofts and the two middle stints on softs.
However Paul di Resta got a sixth place finish from 10th on the grid by saving a new set of softs from qualifying to start the race on and then doing a two stop strategy with a middle stint on supersofts.
He was able to keep up a good pace on softs and leapfrog several cars who stopped three times. Sauber and Lotus will be in a position to try a similar tactic this year. Perez did something similar in Canada and Italy this year. If they can qualify well they could pose a threat in the race.
The time needed for a pit stop in Singapore is very long, which helps cars able to make one less stop. A safety car is likely to feature at some point and this can change the game, allowing cars which lost ground to close up and, if deployed around the time of pit stops, can change the order significantly.
Five or six laps behind a safety car also moves teams into a window of making one less stop, by extending the tyre life.
The chance of a Safety Car at Singapore is very high. There has been at least one Safety Car at every Singapore GP so far with an average of 6 laps spent under Safety Car. This will further encourage teams hoping to do less stops in the races.
Starts are a critical part of the race and strategy can be badly compromised by a poor start, while good starts can make strategists change their plans in the hope of a good result. Much can change. In Hungary, for example, only three drivers completed lap 1 in the same position as their grid slot.
As far as 2012 start performance is concerned drivers have gained (+) or lost (-) places off the start line this season on aggregate as follows:
Gained:
+26 Massa
+21 Alonso, Glock
+19 Perez, Kovalainen
+18 Senna
+13 Vergne
+12 Raikkonen
+11 Pic
+8 Karthikeyan
+7 Kobayashi, Maldonado
+5 Schumacher, Hulkenberg
+4 Hamilton
+3 Di Resta
+2 Button, De la Rosa
+1 Petrov
Held position: Vettel
Lost:
-3 Grosjean, Webber
-6 Rosberg
-14 Ricciardo
Of course good strategy planning also requires good pit stop execution by the mechanics and we have seen tyre stops carried out in less than two and a half seconds by F1 teams. The record is a 2.31s stop in the German GP by McLaren.
It is clear that the field has significantly closed up in pit stops.

Marina Bay Circuit, September 23 2012
The 2012 FORMULA 1 SINGTEL SINGAPORE GRAND PRIX can definitely be classed as a “what might have been” race, as the intervention of two safety cars meant that we were denied an exciting and unpredictable finish. Also the retirements of Lewis Hamilton and Pastor Maldonado spoiled the intense competition at the front.
None of this will have bothered Sebastian Vettel, who took his second win of the season, nor Fernando Alonso, who extended his championship lead over all his rivals bar Vettel.
But despite the anti-climactic ending, the behind the scenes strategy decisions and conditions that shaped the race are very interesting and worth a deeper analysis.
Pre-race expectations
One of the key factors in the weekend was that the gap in performance between the Pirelli soft and supersoft tyres was greater than expected. In qualifying it was as much as 1.6 seconds on some cars. In the race, many teams found that the soft tyres were not working to the optimum; they were designed to be more resistant to high temperatures, but didn’t perform grip wise on the slippery surface.
Degradation was always going to be the limiting factor in Singapore, especially with the rear tyres, so the opening stint was crucial. Everyone expected high degradation in the opening stint. Teams which were unable to get to around lap 13 or 14 on the set of used supersofts from qualifying were going to have to stop three times. And as the pit lane in Singapore is the slowest of the year at 29 seconds, there was a premium to being able to extend the tyre life and do the race in two stops.
So most of the top teams went out aiming to do two stops but waiting to see how bad the tyre degradation would be in reality. Among the rival team strategists there was a suspicion that Red Bull would put Mark Webber, seventh on the grid, on a three stop strategy, as this would gather information on the supersoft tyres in the opening stint and once he moved onto the new softs, which would help Sebastian Vettel’s race effort.
Webber’s tyres were two laps older than Vettel’s so the team could monitor the degradation. However there were also signs that Webber had an over-steering car and this led to higher rear tyre degradation, so he was obliged to do a three stop in any case.
Second Safety car spoils the show
There is always a safety car at Singapore and this year we had two. The first, on lap 33 for Narain Karthikeyan, fell in the window for the second stops and lasted six laps. Most of the front runners took advantage of it to make a stop, although Fernando Alonso and Pastor Maldonado were slightly caught out by it as they had stopped five laps earlier.
But the second one, on lap 40 for Michael Schumacher hitting Jean Eric Vergne, really changed the game. It meant that the cars were able to spend another three laps at reduced speed, making it a total of nine laps behind the safety car. Add in the fact that because of the safety car delays the race ran to two hours so only 59 of the 61 laps were covered and it meant an 18% reduction in the number of racing laps - a real boost for drivers who were gambling on reaching the end without stopping.
This saved quite a few cars, which would otherwise have run into serious trouble in the closing stages of the race without making a third stop.
We would have seen the cars with higher wear coming under pressure from those with better wear, as we saw in Valencia, for example and it would have made for a very exciting finish.
Sebastian Vettel and Fernando Alonso certainly fall into this category. Vettel stopped on lap 10 with clear signs of tyre degradation and Alonso a lap later. Red Bull were on a three stop plan with Webber and may have been obliged to do the same with Vettel without the nine laps of safety car; it certainly helped them to make it to the end in two stops and it’s likely that Alonso would have had the same problem. Ferrari had some issues with overheating the rear tyres in Singapore, so the safety cars were a blessing.
In contrast Jenson Button had been conserving tyres in the opening stint and managed to get to lap 14 before the first stop.
He was preparing the ground for the end of the second stint and the end of the race, when he would be able to attack Vettel on tyres that were four laps newer. The McLaren seemed to be working very well in Singapore and even Hamilton would probably have made the finish in two stops, despite pushing hard in the opening stint and a front tyre issue that forced him to make his first stop on lap 12, slightly earlier than planned.
The first safety car took Button’s advantage away and the second one meant that Vettel had no tyre issues at the end.
Force India – strong result with one car, disappointment with the other
For the second year in a row in Singapore, Force India’s Paul di Resta got a very strong result, in this case a career best fourth place. Di Resta is another driver who was able to make it safely with two stops; he pitted on lap 12 and then took advantage of the first safety car to stop a second time, losing only one track position to Alonso, who had already stopped. He followed him to the flag. He had stayed with the Ferrari for most of the race, but in the final stint the Ferrari was a little faster on the new soft tyres.
Without the second safety car Di Resta too might have struggled on 28 lap old tyres. Luckily for him there were no fast three stopping cars coming up behind. Di Resta benefitted from the Mercedes of Rosberg holding up cars behind him, in the run up to the second stop, creating a gap for him to drop back into.
Team mate Hulkenberg was one of those who tried a three stopper and lost out due to the second safety car.
Hulkenberg had qualified 11th and started on the soft tyre. His strategy was to run a long first stint but he lost time behind Raikkonen and Schumacher in the second stint, just before the safety car. The second safety car meant he couldn’t take advantage of track position and he stopped when it came out, then tried to do two ten lap sprints on new supersoft tyres, but it didn’t work out and he lost further track positions with a third stop on lap 50.
