The 2023 IMSA SportsCar Championship (known for sponsorship reasons as the 2023 WeatherTech SportsCar Championship) is a planned motor racing championship, set to be the 53rd racing season sanctioned by the International Motor Sports Association, which traces its lineage back to the 1971 IMSA GT Championship. It will also be the tenth season of the IMSA SportsCar Championship since the merger between the American Le Mans Series and the Rolex Sports Car Series in 2014, and the eighth under the sponsorship of WeatherTech. The 2023 season marks an overhaul season for the championship, with a change in class structure and a new race on the season calendar at Indianapolis Motor Speedway.

Classes

Grand Touring Prototype class logo
The Porsche 963 (pictured at the 2022 Goodwood Festival of Speed) is one of the prototype race cars that are allowed to compete under IMSA’s new GTP class. It complies with the LMDh regulations.

At the end of the 2022 season, IMSA retired the Daytona Prototype International (DPi) class, which was the premier racing class in the WeatherTech Championship from 2017 until 2022, spanning six seasons. IMSA replaced it with a new class called GTP, named such in tribute to the GTP class from the IMSA GT Championship in the 1980s.

GTP is the new flagship class of the championship, and consists of two sister technical regulations: LMDh (Le Mans Daytona hybrid), and LMH (Le Mans Hypercar). LMDh allows choosing from a base chassis, of which there are four choices, from Dallara, Ligier, Multimatic and Oreca, as well as a specification hybrid system on all cars, with freedom on aerodynamics, bodywork and engine configuration. The LMH regulation allows bespoke hybrid designs, and offers more mechanical design freedom in exchange for elevated development costs. As with the DPi class, GTP is regulated by a Balance of Performance (BoP) system to keep the performance range of each of the cars close together and regulate spending.

The GTP class is made of the same framework as the Hypercar class of the FIA World Endurance Championship, in accordance with the collaborative alliance between IMSA and the French racing organizers ACO, which resulted in the convergence of the two organizer's top class regulations.[1]

After initially announcing discontinuing the sub-championship entirely on August 5, IMSA later declared on September 1 that they would continue the WeatherTech Sprint Cup, a championship comprising only sprint rounds for the GT Daytona (GTD) class. The only difference was that there would be no Sprint Cup-only rounds for 2023, to combat situations such as the record-low six-car GTD entry at the 2022 Chevrolet Grand Prix.[2][3]

Schedule

Indianapolis Motor Speedway is set to return to the championship's schedule for the first time since 2014.

The provisional schedule was released on August 5 2022, and features 11 rounds.[4][5]

  • Mid-Ohio Sports Car Course was dropped from the calendar due to poor track facilities not up to IMSA standards [citation needed]. The track had been on the championship since 2018. The event was replaced with a sprint race at Indianapolis Motor Speedway, marking IMS' return to the championship for the first time since the series' inaugural season in 2014.[4]
  • The Raceway on Belle Isle was also dropped from the calendar as a result of the Belle Isle circuit being replaced in favor of the Detroit street circuit. The track was a part of the championship for every season of the IMSA SportsCar Championship since its inception in 2014, with the exception of 2020 due to the COVID-19 pandemic.[4]

Notes

  1. ^ Race awards qualifying points and sets the starting lineup for the Rolex 24 at Daytona only.
