We don't really know what happened. It was the same body and the same chassis. Benoit replaced the gears, the guide, the motor (rule change) and rerouted the wires (lead wire and light wiring) to make sure everything would be tough enough for a 24-hour race.
On our tracks in Québec, the car was as fast as last year, maybe even faster. But the tracks we have are very different than Area 51 so this is not a good point of comparison. We had 4 cars ready for the race this year, all were about the same overall speed on Area 51 but had different handling characteristics. We made the final choice one hour before the race to go with last year's Lancia as this was the car that offered us the easiest handling (very important in endurance racing).
Obviously, even if we knew that silicone tires could last the whole race, we had prepared 4 pairs on top of the pair we used last year (which was still perfectly good to go). During the race, we switched to other tires (identically prepared) with no change in the handling; we even tried last year's tires at one point. So, the tires were not the explanation for our diminished handling. The traction in and out the corners was the problem.
During my dusk heats, with the lighting change and my driver station's position, I started noticing that the reflection of the temporary silicone trace left on the track after the car passed in a corner was not a continuous line but rather a somewhat dotted line. This meant that we had some hop on the rear axle of the car, more pronounced in the left turns.
At this point, Benoit has not yet analyzed the car but it was probably a problem with a loose bushing or a very slightly bent axle. This is MY early diagnostic but Benoit is the car builder for us.
But as you say, car tuning at this level of competition is an art as much as it is a science. We were very (very!) proud last year when we won this race on Area 51 and we knew it would not be easy to win it again this year. I'm still convinced that our driving is good enough to win this race and we were probably the team with the less «offs» again this year. But just like in F1, you also need a perfect car to win against the other great teams and we didn't have it this year.
Loose bushings, not-perfectly-straight chassis, bent axle, bent motor pod, so many possibilities could explain what happened. This has just fueled our desire to do better next year. Watch for us!
