With Indianapolis still to come and Petit Le Mans looming on the horizon, the No. 4 Corvette Z06 GT3.R remains just 23 points from the GTD PRO championship lead while Chevrolet controls the manufacturer standings.
The 2026 IMSA WeatherTech SportsCar Championship is approaching its decisive final weeks, and Corvette Racing remains firmly positioned to leave the season with considerably more hardware. Only the Battle on the Bricks at Indianapolis Motor Speedway and the 10-hour Motul Petit Le Mans at Michelin Raceway Road Atlanta remain, with championships still within reach for Chevrolet, Corvette Racing by Pratt Miller Motorsports and the drivers of the No. 4 Corvette Z06 GT3.R.
Road Atlanta may be the race everyone is already anticipating, but Indianapolis cannot be treated simply as a stop along the way. The September 20 event is the penultimate round of the championship, and its points could determine whether Corvette arrives at Petit Le Mans chasing the title, defending the lead or attempting to recover from a costly afternoon at the Brickyard.
Milner and Catsburg Remain Within Striking Distance
In the GTD PRO Drivers Championship, Tommy Milner and Nicky Catsburg enter Indianapolis second with 2,409 points. The No. 4 Corvette pairing trails championship leaders Connor De Phillippi and Neil Verhagen by only 23 points, leaving Milner and Catsburg close enough to erase the entire deficit with one strong qualifying session and race result.
Behind them, the championship picture is even more compressed. Andrea Caldarelli and Sandy Mitchell are third with 2,376 points, followed by Harry King and Nick Tandy at 2,365. Christopher Mies and Frederic Vervisch also have 2,365 points, meaning five driver pairings are separated by only 67 points at the top of the standings.
That lack of separation leaves little room for error. A slow pit stop, poorly timed caution, contact in traffic or mechanical problem could dramatically change the order before the championship reaches Road Atlanta. Conversely, a clean Indianapolis weekend could allow Milner and Catsburg to begin Petit Le Mans from the strongest possible position.
The No. 4 Corvette has reached the podium three times this season, including a second-place finish at WeatherTech Raceway Laguna Seca. Although its campaign has included some difficult weekends, the team has continued collecting enough points to remain a championship threat with two races remaining.
No. 4 Corvette Holds Second in the Team Championship
The GTD PRO Teams Championship mirrors the battle between the drivers. Paul Miller Racing’s No. 1 BMW leads with 2,432 points, while the No. 4 Corvette Racing by Pratt Miller Motorsports entry occupies second with 2,409.
Pfaff Motorsports is third with 2,376 points, followed by the No. 77 AO Racing Porsche and No. 65 Ford Racing Mustang, which are tied at 2,365. Just as in the Drivers Championship, five teams remain packed within 67 points of the lead.
Qualifying will also carry added importance because IMSA awards championship points based on starting position. With the margins this narrow, the championship work will begin before the green flag falls. Every position gained—or lost—during qualifying could follow the team all the way to the final hours of Petit Le Mans.
Chevrolet Controls the Manufacturer Battle
Chevrolet’s strongest position can be found in the GTD PRO Manufacturers Championship. According to the official post-VIR IMSA standings, Chevrolet leads with 2,648 points, giving the Bowtie an 87-point advantage over BMW.
Ford sits another 11 points behind BMW with 2,550, followed by Porsche at 2,512 and Lamborghini at 2,484. Chevrolet therefore holds a 98-point advantage over Ford, a 136-point lead over Porsche and a 164-point margin over Lamborghini.
The manufacturer championship awards points based on the highest-finishing car from each brand, making both factory Corvettes important to Chevrolet’s position. The No. 3 Corvette of Antonio Garcia and Alexander Sims delivered Chevrolet’s GTD PRO victory on the streets of Detroit, while Milner and Catsburg have kept the No. 4 near the front of the championship throughout the season.
Chevrolet is pursuing its second consecutive GTD PRO manufacturer title and its 16th manufacturer championship in IMSA competition. Holding the lead is encouraging, but with two races and qualifying points still available, the title is far from secure.
The No. 3 Corvette Still Has a Job to Do
Garcia and Sims stand seventh in the GTD PRO Drivers Championship with 2,238 points, matching the position of the No. 3 Corvette in the team standings. Their chance of winning the driver and team titles has ended, but their role in Corvette Racing’s championship pursuit remains significant.
A strong performance by the No. 3 can take points away from Chevrolet’s manufacturer rivals while helping the No. 4 in its battle with the leading BMW. Corvette Racing has spent decades demonstrating the value of operating as a complete team, and the final two races will demand that same coordinated effort.
Garcia and Sims will also have their own unfinished business. Neither driver has won at Indianapolis or Road Atlanta in the current IMSA configuration, and another victory would provide a satisfying conclusion to a season that has already included their triumph at Detroit.
Customer Corvettes Continue Their Own Championship Pursuits
Corvette will have five Z06 GT3.Rs competing at Indianapolis, with three customer entries joining the two factory-supported Pratt Miller cars. The group includes the No. 13 Corvette from 13 Autosport, DXDT Racing’s No. 36 and DragonSpeed’s No. 81.
Matt Bell and Orey Fidani stand seventh in the GTD driver and team standings with 1,888 points. Fidani, however, remains involved in a much closer individual battle as he pursues a third consecutive Bob Akin Award.
The award recognizes the highest-ranked Bronze-rated driver in GTD and includes an automatic invitation to the following year’s 24 Hours of Le Mans. Fidani enters Indianapolis second in the Akin standings, only 20 points behind Brendan Iribe.
DragonSpeed’s No. 81 Corvette stands 10th in the GTD Teams Championship with 1,698 points, while the No. 36 DXDT Racing entry occupies 13th with 1,552. Giacomo Altoè and Casper Stevenson will share the DragonSpeed Corvette at Indianapolis, where Stevenson returns after earning the GTD pole at the circuit one year ago. Mason Filippi will be joined in the DXDT Corvette by Canadian racer Robert Wickens.
Indianapolis Comes First
The TireRack.com Battle on the Bricks is scheduled for Sunday, September 20, at 3:10 p.m. ET. Unlike the six-hour Indianapolis races held during the previous two seasons, the 2026 event returns to a two-hour, 40-minute sprint format.
That shorter distance will leave less time to recover from an early mistake or an unfavorable strategy call. Teams will need to execute cleanly from the opening lap, and the crowded multiclass field around Indianapolis Motor Speedway’s 2.439-mile, 14-turn road course will make traffic management another constant concern.
The race will air live on NBC beginning at 3 p.m. ET, with streaming coverage available through Peacock in the United States. IMSA’s official YouTube channel will provide international coverage.
Everything Leads to Road Atlanta
After Indianapolis, the championship will move to Michelin Raceway Road Atlanta for the season-ending Motul Petit Le Mans, scheduled for September 30 through October 3. The 10-hour endurance race will place the championship contenders into one of the most demanding environments on the IMSA calendar.
Road Atlanta combines elevation changes, heavy traffic, limited passing opportunities and the transition from daylight into darkness. Strategy can change repeatedly over 10 hours, but the championship may ultimately come down to the final pit stop, the final restart or one pass through the circuit’s high-speed closing sequence.
Corvette Racing will arrive with a legitimate chance to claim the GTD PRO Drivers and Teams championships, while Chevrolet remains in control of the Manufacturers Championship. The margins are close enough to create uncertainty, but the opportunity is unmistakable.
Before Corvette can fight for everything at Road Atlanta, it must first survive Indianapolis. If Milner, Catsburg and the No. 4 team can deliver a clean weekend at the Brickyard, Corvette Racing could enter Petit Le Mans with all three championships directly in front of it—and 10 hours remaining to finish the job.
