Le Mans 2013: Audi vs. Toyota Analysis

Le Mans 2013 was very special in many ways and will be in our minds for very sad moments, but also for a very tough battle between the two manufacturers Audi and Toyota. As always during the last years I’ve done some analysis of the race afterwards with some interesting details.

The Audis were quick, that was no suprise and Toyotas chance was better fuel consumption. To be precise, the petrol car had a larger fuel tank capacity compared to the diesel, so they were able to stay longer.

How quick is quick?
Having a look at the topspeed shows a really fast #1 Audi, but on the average speed, the #3 makes a significantly more constant performance. During the race different sources told the story of one Audi didn’t take advantage of the blown diffusor or maybe the blown-diffusor-engine-maping. If this is correct, I guess it was the #3 car and I will explain later why. LM2013_Topspeed_Audi_Toyota Remarkable: Audi #2 did slower speeds and also the expected quicker Toyota #7 had slower topspeeds than the sister car #8. There could be different reasons why. Depending on the position of the speed trap on the track, some cars could already be under braking while others were still flat out. There are good reasons, that the #2 Audi tried to save fuel and one opportunity is early throttle lift and rolling through the corners(sounds funny „rolling“ with more than 300kph).

To find out how quick quick is, looking at the topspeed is only one tiny bit on the way to the answer. Drag and topspeed are usually no friends, so a closer look at the highspeed handling part of the track should be the next step. Porsche curves – the „wow“ part of the track. An onboard on a clear lap from one of the prototypes is really breath taking. No matter what car, it is very impressive, but there are still differences. Highspeed and a good handling by a lot of downforce these are the key factors for this part of the track.

Take a look at the timing at this part of the track. The Audis fastest times were over half a second quicker of… wait… only the #1 and #2 Audis were lightspeed quick in this part.LM2013_PorscheCurves_Audi_Toyota The #3 car was in the same region as the Toyotas and over the race even slower. Isn’t that interesting? Let me remind you of the rumours a bit above of this text and make your own thoughts. Anyway noone is surprised that Audi in general was able to go a lot faster here than Toyota.

And they had to. After quailfying it was said Toyota could go 12 laps while Audi had to refill after 10 laps. In that case, Audi had to go around 1.5s per lap faster than Toyota. Looking at the pitstops, the Toyotas were not able to use their advantage. The wining #2 car wining #2 car stood just 3:50min longer in the pits – that is just 0,67s per lap.

There are different reasons for this. The weather made almost every calculation to a kind of guessing, very many and long safety car periods didn’t help as well. In opinion the use of three safety cars t the same time is wrong. During the SC period they should try to bring all three groups together and form one complete group. But back to the analysis…

I have to say at this point, that the pitcrews did an awesome job – from every team! They did change tires like clockworks and it is a pleasure to watch these guys dancing around the cars! Very well done, boys!

After the details looking at the total lap and the single sectors let get to the result, that the #1 car was the set to make the pace. The guys are young, quick, already very Le Mans experienced and two times winners. Without the alternator/generator failure I think they would have won the race by far. The #2 the most experienced team was the backup crew. Quick, but set to be just a bit faster than the opponent, fuel saving compared to the #1 car. Audi #3 was on a different strategy I think. Setupwise closer to the Toyotas than to their sister cars. Interestingly was the #8 the faster car than the #7 and I think they had more problems than said. Maybe the hybrid systems didn’t have the performance(temperature of the supercaps?).

These are all my thoughts and I may be wrong, but I would love to set these assumptions for discussions – feel free to say your opinion!

The terrible crash at the beginning made everyone feel sad, but the teams did, what Allan loved most and from my point of view is this the best way to show his respect. The battle between Audi and Toyota was awesome, but there is something unsaid, but you can feel the deep respect both teams have for the work, the knowledge and the spirit. It is far, far more respectful than years ago. You can feel it and you can see it during fights on the track. And that’s the way we want to see the competition!
