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:
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.”

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.
The Chevrolet Fan Experience
Chevrolet aficionados will have no shortage of things to see and do at the Rolex 24. That’s because three locations around Daytona International Speedway – the Chevrolet Experience Center, the Chevrolet Injector and Chevrolet Motorsports Display – will be full of Chevrolet vehicles that spectators can learn more about throughout the weekend.
Each location will open at 9 a.m., Friday and Saturday; and 8 a.m., Sunday.
The Chevrolet Experience Center is located next to Victory Lane. The main attraction for Corvette enthusiasts is the 2023 Chevrolet Corvette Z06 – a nearly mirror image of the Corvette C8.R race car. Among its features is a 5.5L, flat-plane V8 capable of reaching 8,600 rpms. The 670hp output is the highest for any naturally aspirated V8 produced by any production car in the world.
In addition, Chevrolet vehicles on display at the Experience Center include the 2022 Corvette Stingray IMSA GTLM Championship Edition, Camaro ZL1, Tahoe High Country and Colorado ZR2, plus a Corvette Z06 chassis.
The Chevrolet Motorsports Display in the Fan Midway will have a number of attractions:
• Production vehicles such as the Corvette Stingray with the Z51 package, Tahoe RST, Blazer RS, Colorado Z71, Silverado 2500 HD Crew Carhartt, Camaro ZL1, a Corvette C8.R showcar and a Stingray cutaway chassis.
• Samples of Chevrolet engines, performance parts and accessories available to fans for purchase from local Chevrolet dealers
• Corvette Racing t-shirts for fans who sign up with Chevrolet
At the Chevrolet Injector, nearly 20 different Chevrolet vehicles are on display throughout the four levels of fan access. Models include Trax LT, Equinox RS, Traverse Premier, Trailblazer ACTIV and RS, Blazer Premier and RS, Silverado 1500 Trailboss, Silverado HD and 2500 Crew Cab LTZ, Corvette Stingray Convertible, Camaro ZL1 and 2SS Coupe, Colorado Z71 Crew Cab and ZR2, Suburban 4WD High Country and Tahoe LTZ
As at the Chevrolet Motorsports Display and Chevrolet Experience, Chevrolet product specialists will be on-hand to answer questions on each model of Chevrolet vehicle throughout the weekend.
Corvette Z06 at Barrett-Jackson
Also of note, the first 70th Anniversary Edition 2023 Corvette Z06 off the production line will be auctioned Saturday at the annual Barrett-Jackson event in Scottsdale, Ariz. Corvette Racing veterans Oliver Gavin and Ron Fellows will be on-hand and take part in the auction.
