Background

WeatherTech Raceway Laguna Seca, where the race was held.

International Motor Sports Association's (IMSA) president John Doonan confirmed the race was part of the schedule for the 2023 IMSA SportsCar Championship (IMSA SCC) in August 2022. ^[1] It was the tenth consecutive year it was part of the IMSA SCC. ^[2] The 2023 Motul Course de Monterey was the fourth of eleven scheduled sports car races of 2023 by IMSA, and the second of seven races of the WeatherTech Sprint Cup. ^[3] The race was held at the eleven-turn 2.238 mi (3.602 km) WeatherTech Raceway Laguna Seca on May 14, 2023. ^[4]

After the Grand Prix of Long Beach four weeks earlier, Nick Tandy and Mathieu Jaminet led the GTP Drivers' Championship with 955 points, ahead of Pipo Derani and Alexander Sims with 954 points followed by Filipe Albuquerque and Ricky Taylor with 934 points. ^[5] With 375 points, the LMP2 Drivers' Championship was led by John Farano, Scott McLaughlin, and Kyffin Simpson with a twenty-five point advantage over Scott Huffaker, Mikkel Jensen, and Steven Thomas. ^[5] Ben Barnicoat and Jack Hawksworth led the GTD Pro Drivers' Championship with 1067 points ahead of Jules Gounon and Daniel Juncadella with 994 points. ^[5] In GTD, the Drivers' Championship was led by Bryan Sellers and Madison Snow with 1008 points, ahead of Roman De Angelis and Marco Sørensen with 909 points. ^[5] Cadillac, Lexus, and BMW were leading their respective Manufacturers' Championships, while Porsche Penske Motorsport, Tower Motorsports, Vasser Sullivan Racing, and Paul Miller Racing each led their own Teams' Championships. ^[5]

On May 4, 2023, IMSA released the latest technical bulletin outlining Balance of Performance for the GTP, GTD Pro, and GTD classes. In GTP, both Cadillac and BMW received weight reductions, whilst Porsche and Acura received weight increases compared to Long Beach. The Cadillac ran at 1030 kg, the BMW ran at 1031 kg, the Porsche ran at 1038 kg, and the Acura ran at 1049 kg. As a result, the Cadillac ran on 511 kilowatts of power, the BMW on 512 kW, the Porsche on 514 kW, and the Acura on 520 kW. Maximum stint energy figures were also adjusted. ^[6] In GTD Pro and GTD, the only changes in BoP are a 10 kg weight increase for BMW and a 5-liter decrease of fuel tank capacity for McLaren. ^[6]

Qualifying

Matt Campbell (pictured in 2024) helped take the No. 7 Porsche's first pole position of 2023.

Saturday’s afternoon qualifying was broken into three sessions, with one session for the GTP, LMP2, and GTD Pro and GTD classes, which lasted for 20 minutes for the GTP session, and 15 minutes for the LMP2, and GTD Pro/GTD sessions. ^[10] The rules dictated that all teams nominated a driver to qualify their cars, with the Pro-Am LMP2 class requiring a Bronze rated driver to qualify the car. The competitors' fastest lap times determined the starting order. IMSA then arranged the grid to put GTPs ahead of the LMP2, GTD Pro, and GTD cars. ^[20]

Qualifying was broken into three sessions. The first was cars in the GTD Pro and GTD classes. Klaus Bachler qualified on pole in GTD Pro driving the #9 Pfaff Motorsports entry. Alec Udell qualified on pole in GTD driving the #92 Kelly-Moss with Riley entry, besting Roman De Angelis in the #27 Heart of Racing Team entry. ^[21]

The second session of qualifying was for cars in the LMP2 class. George Kurtz qualified on pole for the class driving the #04 car for CrowdStrike Racing by APR. ^[22]

The final session of qualifying was for the GTP class. Matt Campbell qualified on pole driving the No. 7 car for Porsche Penske Motorsport, beating Mathieu Jaminet in the sister #6 car for Porsche Penske Motorsport by less than one tenth of a second. ^[23]
