Cadillac Racing driver lineup for Grand Touring Prototype class
No. 01 Cadillac (qualified fourth)
Sebastien Bourdais: “I think (qualifying) is a strong start; obviously not the pole but as close as we can get without getting it. I think it bodes well for the race. Now it’s just about executing, making no mistakes. It’s like a crash course of learning. There’s so much to absorb, so much to figure out, so much to strategize with the new car because up until not long ago we were completely in practice mode trying to get the car reliable, tire testing, this and that and the other and then all of a sudden get ready for the biggest race of the season. It’s a big adjustment, mind switch and get into the racing vibe for a 24-hour race with my two great teammates. We’ve learned a lot of the car and we’re gaining confidence.”
Renger van der Zande: “I’m excited how close the field is; everybody is within a couple of tenths (of a second) and that’s an impressive effort for a new class, new regulations and for the systems that have been put in place to go racing for the future. Starting fourth is an amazing achievement and a compliment to whole team.”
Scott Dixon: “I’m looking forward to the race this weekend. It’s kind of crazy when you look at the preparation from when the first car arrived to its development of it and how the technology has shifted. It’s been fun to work with it, so I think everyone is excited to finally get to the race. There’s been a lot of prep and lead time and expectations for this one. It’s one of my favorite races of the year. You get to drive the car a lot, you get to have some fantastic racing. I think this year one of the largest fields that we’ve seen in years. It’s going to be fun, but I think it will possibly a race of reliability as well. Knock on wood that we’ve done as much as we can as a group between Cadillac, GM and Chip Ganassi Racing that we can make it to the win and be fighting for the win.”
No. 02 Cadillac (qualified fifth)
Richard Westbrook: “We had a productive three days at the Roar. We got exactly what we were searching for, which is more miles, more knowledge about the car, more knowledge about the tire and more knowledge about the whole new formula that we’re going into. Now we’re all out there together, we can see our pace against everyone else and it just makes us all more even more determined and excited with one eye on the future.”
Earl Bamber: “A good qualifying with everyone learning these cars. We can see already that it’s ultra-competitive and it’s a true credit to IMSA, the manufacturers, the teams and everyone who’s been involved to make for a great race.”
Alex Lynn: “I really am enjoying driving this car and it’s giving me really good feedback. We’re improving so much with each session and it’s a really enjoyable job when you start making huge strides on improving this brand-new vehicle that we got, so I’m excited for the race."
No. 31 Whelen Engineering Cadillac (qualified sixth)
Pipo Derani: “The car is working well and the most is that it looks like we have a good car for the race. That’s our goal. We’re trying to use every session that we have, even qualifying, to learn more about our equipment. Any time we can be on track it helps us get better and improve the car. Not the fantastic final result in qualifying but lots of data has been gathered that will help us next week.”
Alexander Sims: “We’re working through things in the practice sessions and there are still some things for us to learn with these new cars. We have time this week to try a few things. In the first part of the race we have to take it step by step and try to improve, even if it means making changes during the pit stops – just tweaks we can do during the race – because it’s about being fast at the end and being there at the end. It’s an incredibly tight field and Pipo (Derani) was compromised in qualifying with the red flag, not getting a reference beforehand while others did.”
Jack Aitken: “We didn’t get a huge amount of mileage (during the Roar) just with red flags and weather, so this week we’ll keep building on what we’ve learned and get the car dialed in more on specifics. We’re all disappointed with the quals, but it’s probably the least important qualifying of the year for us. I’m looking forward to getting track time in practice and excited to compete for the first time in the race with this team.”
