CORVETTE RACING AT DAYTONA: Pre-Race Notes


DAYTONA BEACH, Fla. (Jan. 26, 2022) – Corvette Racing begins its 24th season of competition this weekend with the Rolex 24 At Daytona to start the IMSA WeatherTech SportsCar Championship. It’s a new season in more than one way as it marks the team’s first foray into GT Daytona (GTD) PRO competition.
The team logged three days of testing plus Sunday’s 100-minute qualifying race to set the Rolex 24 grid. Throughout the weekend, Corvette Racing engineers gathered useful data on a number of new items that are unique to the GTD-spec version of the Chevrolet Corvette C8.R.
The twice-around-the-clock endurance race around at the 3.56-mile road course inside the Daytona International Speedway presents a number of challenges and elements that aren’t found anywhere else in racing, according to two members of Corvette Racing:
NICKY CATSBURG, NO. 3 MOBIL 1/Sirius XM CHEVROLET CORVETTE C8.R: “I love this event and being at Daytona. You’re going to straight into it and starting the season with one of the most important races. There’s no way to ease into things. You have to be on it, and this sets the tone for the season. It’s a unique situation compared to Europe. I’ve done this event several times now, so I’m used to it. Plus it’s a unique setting. The track is cool and fun with the banking. Plus you have a GT class that is this big. It’s an event we all look forward to every year.”
NICK TANDY, NO. 4 MOBIL 1/SiriusXM CHEVROLET CORVETTE C8.R: “Daytona is always cool because it’s this big, standalone event. Yes, it’s part of a points-scoring championship but it’s still the Daytona 24 Hours. So it’s always cool. It’s different this year, especially for us on the 4 Corvette side for two reasons. For one, we have this new-spec C8.R GTD car so that’s different and new. I was telling someone the other day that Corvette Racing have been coming here for years and years and years with the same kind of formula and the same knowledge about how things should play out. This year it’s all a bit different and new. It’s fresh and very interesting to go into something new while learning and experimenting while not really knowing how things will work. Plus it’s a single event for our side of the garage before we go off to the WEC. But Daytona still has that big atmosphere and big levels of anticipation of what’s coming and what’s ahead of you.”

To put that in perspective, Corvette Racing is more than halfway to the distance traveled by Apollo 13 – the longest manned spaceflight in history: 622,268 miles. That means Corvette Racing has raced to the moon!
What’s New on the GTD PRO Corvette?There have been lots of questions about changes to the Corvette C8.R for the IMSA GTD PRO class. There is quite a bit of work the Corvette Racing team has undertaken to transition the car from GTLM spec to meet GTD technical regulations. Here are a handful of key areas:
1. The mass of the C8.R is increased by 65 kilograms (143 lbs.) relative to Daytona 2021. To accommodate the ballast box required by the GT3/GTD regulations to hold the extra weight, the Corvette Racing team had to reconfigure the entire passenger side floor compartment. This required the move of the air conditioning unit, fire bottle, battery box and other electronics. This was no small feat with integration requiring significant effort by the Corvette Racing engineering team.
2. The 2022 Corvette GTD entry is running on customer Michelin tires, which are required for the category. This is a change from GTLM where the C8.R ran on confidential tires – ones that were specifically designed for Corvette Racing.
3. The power output of the C8.R’s flat-plane V8 is significantly reduced under GTD rules. The difference between the size of this year’s Daytona air restrictor and 2021 is nearly 1.7 mm.
4. Related to that, the GTD PRO Corvette is running with a higher angle of attack on the rear wing than previous years. This creates a greater level of drag on the race car and significantly reduces top speed.
5. The addition of ABS is required under GT3/GTD rules. As many observers are aware, Corvette Racing tested this in competition for the first time last year at Belle Isle in the GTLM Corvette. The system continued to be improved throughout testing late last year and early this season both virtually and in the real world.
6. The differential of the Corvette C8.R must now comply with GT3/GTD regulations. A limited slip differential configuration is permitted with a single homologated set of ramps. This required removal of some tuning options previously available on the GTLM Corvette.
7. Unlike other GTD teams, the C8.Rs are required to run with torque axle sensors. These directly measure the output of the Corvette engine and the data is used by IMSA for the BOP process.
