Corvette Racing Keeps Its Two-Car GTD PRO Lineup for 2027
Corvette Racing by Pratt Miller Motorsports will return to the IMSA WeatherTech SportsCar Championship with two Chevrolet Corvette Z06 GT3.R entries in 2027. IMSA confirmed on October 7 that the team’s four full-season drivers will remain in the same pairings for a fourth consecutive year.
Tommy Milner and Nicky Catsburg will share the No. 4 Corvette, while Antonio Garcia and Alexander Sims will continue in the No. 3. The announcement gives the factory-backed GTD PRO operation continuity as the Z06 GT3.R enters its fourth season of competition.
The 2027 full-season lineup
| Entry | Full-season drivers | Continuity note |
|---|---|---|
| No. 3 Corvette Z06 GT3.R | Antonio Garcia and Alexander Sims | Paired since 2024 |
| No. 4 Corvette Z06 GT3.R | Tommy Milner and Nicky Catsburg | Paired since 2024 |
IMSA’s announcement identifies those four as the full-season drivers. It does not name additional drivers for the longer endurance rounds, so any Rolex 24 at Daytona or other endurance additions remain unconfirmed in this report.
Why continuity matters
Garcia will begin his 19th year with the Corvette program in 2027, while Milner will start his 17th. Sims returned to Corvette Racing in 2024 after winning IMSA’s top-class championship with Cadillac in 2023. Catsburg moved from an endurance role into a larger IMSA program after racing Corvette machinery in both IMSA and the FIA World Endurance Championship.
Keeping the pairings intact reduces the adjustment work that often comes with a driver change. In a GT3 program, drivers must agree on seating, controls and setup direction while sharing a car across sprint and endurance formats. Familiarity does not guarantee results, but it allows the team to begin the season with an established technical vocabulary and a sizable base of race data.
A strong manufacturer result, but unfinished business
Chevrolet secured its second consecutive GTD PRO manufacturers’ championship at the 2026 Motul Petit Le Mans finale. IMSA says that was Chevrolet’s 16th GT-class manufacturers’ title since the Corvette Racing program began in 1999, and its sixth IMSA GTD PRO or GT Le Mans manufacturers’ crown since 2014.
The No. 4 crew entered the 2026 finale in the championship fight but finished the season third in the driver standings after contact sent the car into the gravel. The No. 3 won at Detroit during the season. Those results help explain the team’s decision to value continuity: both cars demonstrated winning pace, even though the year did not produce the drivers’ title the No. 4 team was chasing.
The Z06 GT3.R’s fourth season
The Z06 GT3.R first won in IMSA in 2024, when Garcia and Sims took the Chevrolet Grand Prix at Canadian Tire Motorsport Park. They added another victory at Virginia International Raceway in 2025 and won on the Detroit street circuit in 2026. A customer Corvette also won the GTD class at the 2025 Rolex 24 at Daytona.
Those milestones show the car can succeed on permanent road courses, street circuits and long-distance events. The 2027 challenge will be converting that range into a complete championship campaign while GTD PRO rivals continue refining their own established GT3 cars.
What comes next
This announcement settles Corvette’s two full-season pairings, but it is not a complete 2027 race plan. The team still has to confirm endurance additions and event-by-event details. Chiefs Review will treat those as separate news when the team, Chevrolet or IMSA publishes them.
