Udell to start second in GTD, Catsburg third in GTD PRO qualifying ahead of Six Hours
WATKINS GLEN, NY (June 21, 2025) – Corvette Z06 GT3.Rs will start on the first and second row of the GTD and GTD PRO grids after qualifying for the Sahlen’s Six Hours of The Glen on Saturday at Watkins Glen International.
Alec Udell was the quickest Corvette driver in the 15-minute qualifying sessions Saturday for DXDT Racing. For the second GTD race in a row, he will start on the outside of the front row after a lap of 144.999 (116.572 mph) in the No. 36 Chevrolet Corvette that he will share with factory driver Charlie Eastwood and Salih Yoluc.
Udell also was second in GTD qualifying in the last race for the class in the IMSA WeatherTech SportsCar Championship at WeatherTech Raceway Laguna Seca. He also was second-quickest in Friday’s opening practice session and fastest in GTD following Saturday morning’s final practice session.
In GTD PRO, Nicky Catsburg led the attack for Corvette Racing by Pratt Miller Motorsports. He qualified third in the No. 4 Corvette that he’ll drive with Tommy Milner after a lap of 1:45.296 (116.243 mph). He was less than two-tenths of a second and three positions ahead of teammate Alexander Sims in the No. 3 Z06 GT3.R – a year after he and Antonio Garcia finished the Sahlen’s Six Hours third in class.
Watkins Glen also serves as the third of five rounds in the IMSA Michelin Endurance Cup with the Corvette program already having a victory this year courtesy of GTD team AWA, which will start 19th in class Sunday. At Watkins Glen, points will be awarded at the three-hour mark as well as the race’s end.
In addition to more IMEC points, the Corvette Racing program will go for a third – and perhaps fourth – class victory in the Sahlen’s Six Hours.
The Sahlen’s Six Hours of The Glen is scheduled for 12:10 p.m. ET on Sunday, June 22. The race will air live on NBC from noon to 3 p.m. with full streaming coverage on Peacock. IMSA Radio will stream audio coverage at IMSA.com along XM 206, SiriusXM Online 996.
CORVETTE Z06 GT3.R POST-QUALIIFYING DRIVER QUOTES
ALEC UDELL, NO. 36 CORVETTE Z06 GT3.R – SECOND IN GTD:
“Not a bad place to start. I don’t know how much more was in the car. It was a good lap, but I think maybe a tenth was what I feel like I left on the table there with the tire prep and putting it all together. The second push lap, I think, was a little bit better but I just lost a little in the last corner because I put a bit too much heat in the tire and then that was kind of it. We went for one more but it wasn’t there. I’m happy, really happy. I think the DXDT guys are showing consistency with pace and prep for the car and everything, so it’s nice to be at the front and nice to show that we’ve got the speed to be where we consistently put ourselves. It’s a long race and we just have to focus on the execution for the next six hours tomorrow.”
NICKY CATSBURG, NO. 4 CORVETTE Z06 GT3.R – THIRD IN GTD PRO:
“It wasn’t bad in qualifying although the gap will make for a difficult race. Usually we are pretty strong in qualy and then we struggle in race. So we need to keep looking at trying to make a fast race car for tomorrow. I wasn’t really expecting P3 in that session so it’s kind of okay… same as this morning. It’s just that the gap (to the front row) surprises me. We knew the Lambo was fast but we didn’t know the BMW was going to be that fast. Let’s see, although I’m afraid that in the long run, we might not be so strong. So it’s something we have to work on overnight and make sure to get in the right window.”
ALEXANDER SIMS, NO. 3 CORVETTE Z06 GT3.R – SIXTH IN GTD PRO:
“It feels like we’ve got a nice racecar. I felt pretty confident driving it. I was just a little bit behind the curve in terms of the amount of laps that I’ve been able to do today and none yesterday. I just wasn’t really able to attack that first lap. I was building up to it a touch, which honestly, in the circumstances, I’m perfectly happy with what we’ve done. It seems about right. It’s a long race tomorrow with a bunch of pit stops. Like always… trying to keep a clean car, trying to be smart on strategy and just play a smart race because it seems like others have got more pure pace than us. We’re still in the mix so let’s have a smart race and get a good result.”
OREY FIDANI, NO. 13 CORVETTE Z06 GT3.R – 19TH IN GTD:
“Not exactly where we hoped to be on the grid, but the Sahlen’s Six Hours is a long race and anything can happen. We’ve got a solid car, a strong lineup, and a team that knows how to fight. We’ll keep our heads down, stay clean, and push forward tomorrow.”
