Start times, TV schedule: The IMSA WeatherTech SportsCar Championship will conclude the 2022 season this weekend with the Motul Petit Le Mans at Michelin Road Atlanta, which also will mark the end of the line for the DPi class.
The premier Daytona Prototype international category, which started in 2017, will be replaced by the new Grand Touring Prototype (GTP) class with its LMDh cars that will establish a bridge to Le Mans.
For the third time in four years, an Acura will be crowned the champion in DPi as the No. 10 of Wayne Taylor Racing holds a 19-point edge over the No. 60 of Meyer Shank Racing.
Last year, WTR’s No. 10 entered the season finale with a 19-point lead but lost the title to the No. 31 Cadillac of Action Express.
Full-time WTR drivers Filipe Albuquerque and Ricky Taylor (who will be joined by Brendon Hartley in the No. 10 this weekend) have a series-leading four victories this season. The MSR duo of Tom Blomqvist and Oliver Jarvis (who will be joined by Helio Castroneves this weekend) won the Rolex 24 at Daytona and have five runner-up finishes this year.
Championship scenarios in the other four categories:
—GTD Pro: Points leaders Matt Campbell and Mathieu Jaminet will clinch the title by starting in their No. 9 Pfaff Motorsports Porsche 911 GT3 R.
–GTD: There are 140 points separating the top four teams with Roman De Angelis and the No. 27 Heart of Racing Aston Martin Vantage GT3 leading by 45 points.
–LMP2: John Farano is first in the driver standings by 33 points over Dwight Merriman and Ryan Dalziel. In the team standings, the No. 52 PR1 Mathiasen Motorsports leads by 19 points over the No. 8 Tower Motorsport (Farano’s team).
–LMP3: No. 54 CORE autosport drivers Jon Bennett and Colin Braun lead by 83 points over the No. 74 Riley Motorsports of Gar Robinson.
With the 10-hour race requiring an extra driver, several stars from other racing series have been added. In addition to Castroneves, Scott Dixon and Ryan Hunter-Reay will serve as third drivers in Chip Ganassi Racing’s pair of Cadillacs.
Jimmie Johnson also will be making his last DPi start in the No. 48 Ally Cadillac with Mike Rockenfeller and Kamui Kobayashi. Petit Le Mans could mark the last start in an IMSA prototype for Johnson, who has said limited inventory likely will keep him out of the GTP category in the Rolex 24 next year.
