Audi won the 12 Hours of Sebring 2012 at Sebring International Raceway. The #2 Audi R18 of Audi Sport Team Joest covered 325 laps over 12 hours, a race distance of 1,956 km. The winning crew: Dindo Capello, Tom Kristensen and Allan Mcnish. The margin to second place was 4 laps — a clear, controlled win. The fastest manufacturer also produced the winner.

How the Lead Was Won

Across the race we counted 2 lead changes among 2 different cars in the LMP1 class. At the closest point, first and second were only 0.7 s apart. For 6 of 10 measured hours the gap stayed under 30 seconds.

The leader was never fully out of reach, but the pressure came in waves rather than all race long.

Figure 1 shows how that gap moved over the distance.

Manufacturer Pace

We rank pace by the average of each manufacturer’s fastest lap. That measures real speed over the distance instead of one lucky lap. The order at the top: Audi (202.1 km/h), Lola (197.4 km/h), Honda (197.1 km/h).

Between the fastest and the slowest manufacturer in the LMP1 class lie 6.2 km/h. That is a wide spread. At this track, the concept differences show clearly.

Reliability by Class

4 of 29 cars did not make the finish — an overall retirement rate of 14%. The heaviest toll fell on LMGTE Pro with 40%, while LMP1 came through best at 0%.

Over this distance, reliability is a result in itself. A car that stops scores nothing, no matter how fast it was.

Figure 3 compares the classes directly.

Efficiency Over the Distance

Our efficiency score multiplies average lap speed by laps completed and compares that to the class average. It rewards cars that were fast and stayed out of trouble. A value of 1.000 is exactly class average.

The top score goes to #2 Audi with 1.091. That is the winning car — speed and durability came from the same package.

The Closing Phase

In the final hour, 76% of the field held position within ±1 place (n = 29). Most of the order was set, but a few fights ran to the end. The biggest single move came from #12 Lola, 6 places back.

Fastest Lap and Class Gaps

The fastest single lap of the race belongs to #1 Audi (Audi Sport Team Joest): 1:46.567 at 203.3 km/h. Crew: Marcel Fässler, André Lotterer and Benoit Tréluyer.

Between LMP1 and LMP2 sits a pace gap of 4.3 s per lap. That number decides how much traffic the leaders have to work through.

Class winners — LMP1: #2 Audi (Audi Sport Team Joest), LMP2: #44 Honda (Starworks Motorsports), LMGTE Pro: #71 Ferrari (Ferrari AF Corse), LMGTE Am: #88 Porsche (Team Felbermayr-Proton).

Putting the Race in Context

The winner averaged 163.0 km/h across 1,956 km. On a 6.019 km lap, that is the pace the whole strategy had to sustain.

We calculate the same metrics for every race in the archive: pace order, reliability by class, lead changes, winning margin, closing stability and efficiency. That makes this race directly comparable with every other round of the 2012 season — and with the seasons before it.

All figures are derived from the full classification of every race hour and are recalculated with each build.
