Le Mans winner Marcel Fässler in the number 2 Audi R18 e-tron quattro and Loïc Duval in the number 1 sister car already noticed irregularities on the first timed laps of the qualifying session. The complex control systems for fuel consumption and the hybrid system were apparently receiving wrong signals that made optimal lap times impossible. As the reasons for the faulty lap trigger signal could not be found and corrected in the mere 25-minute qualifying session, Audi had to settle for grid positions four for Marcel Fässler/André Lotterer/Benoît Tréluyer (CH/D/F) and six for Lucas di Grassi/Loïc Duval/Tom Kristensen (BR/F/DK).
But the free practice sessions give Audi reason for hope. As soon as the defect has been corrected the hybrid sports cars should be able to battle for top positions. In the first free practice at Austin, Marcel Fässler achieved the best time ahead of his team-mate Lucas di Grassi. In the third free practice, Loïc Duval was in front of Marcel Fässler. In dry weather in the first and third practice sessions and heavy rain in the second one, Audi thoroughly prepared for the highly changeable conditions prevailing in the south of Texas this weekend. High humidity, temperatures of more than 30 degrees centigrade, rain showers and the chance of thunderstorms are making forecasts difficult. However, in a 6-hour endurance race top results are possible even from the current grid positions.
The starting signal in Texas will be given on Saturday at 17:00 local time (00.00 CEST). Eurosport in Germany will air full-length coverage of the race.
Quotes after qualifying
Dr. Wolfgang Ullrich (Head of Audi Motorsport): “We were not unfortunate but both of our cars failed to function the way they should have. There was a problem with the lap trigger signal. Given the complexity of the systems, a correct run of the lap is extremely important but that didn’t work in qualifying with either car.”
Chris Reinke (Head of LMP): “This is a sobering result for us because we didn’t have the chance to use our full potential. We’re going to correct the issue on both cars before the race. Then we’ll be able to attack with full strength.”
Ralf Jüttner (Team Director Audi Sport Team Joest): “We had problems with the lap trigger signal. The systems are very complex with these cars. For the drivers, it must have felt as if they were driving a totally different car than in the previous practice sessions. The race will be on Saturday, that’s when everything counts. By that time, we’re going to provide our drivers with flawless cars again.”
Marcel Fässler (Audi R18 e-tron quattro #2): “For me, qualifying was difficult because we had problems with the lap trigger signal. That distracted me a bit while I was driving. We were clearly beaten below our potential. We tried to make the best of the situation. That’s why I got into the car a second time in order to improve our average lap time. Of course it would have been great to start the race from the front row but from the second row a lot is still possible too. The race will be very interesting.”
André Lotterer (Audi R18 e-tron quattro #2): “It was a difficult qualifying session which, unfortunately, didn’t go smoothly due to problems with the lap trigger signal. That’s why we weren’t able to use our maximum potential. But the race is long and we’ve got a good car. I’m looking forward to Saturday.”
Benoît Tréluyer (Audi R18 e-tron quattro #2): “We had a problem with the lap trigger signal. That impaired us quite a bit because the car depends on it. We’re going to resolve the issue by tomorrow. It’s better to have such a problem in qualifying than in the race – because, obviously, it’s the race that counts.”
Lucas di Grassi (Audi R18 e-tron quattro #1): “We didn’t have a good qualifying session because we had problems with the lap trigger signal. That’s really very disappointing because we still set the best time in the third free practice and were fast in the other sessions as well. I’m sure that we’re going to correct the problems by tomorrow and have a clean race then. Then I’m sure we’ll be further towards the front again too.”
Loïc Duval (Audi R18 e-tron quattro #1): “We’d been looking forward to qualifying because our times in practice had been good. Unfortunately, we had problems with the lap trigger signal, which greatly impaired our qualifying. But I’m sure that we’re going to resolve everything by tomorrow. Even though we’re starting from position six, anything’s still possible with our competitive car. We’re determined to move forward.”
Tom Kristensen (Audi R18 e-tron quattro #1): “It’s great to finally be sitting in the car again after Le Mans – especially on such a nice and modern track as the Circuit of the Americas. The car was running perfectly in the practice sessions and the team did a great job – be it in the sessions on the muggy afternoon or during the thunderstorm in the night practice. That gives us hope for a great race that we’re looking forward to even though the qualifying session was less than perfect.”
