Background

In January 2021, Acura formally announced they would participate in IMSA's new GTP class in 2023 using an LMDh-compliant racing design.[10] On December 6, 2021, Acura announced it would work with Oreca as their chassis supplier, making Acura the first manufacturer in the LMDh ruleset to select Oreca as their partner.[11] It was also confirmed on the same day that Meyer Shank Racing and Wayne Taylor Racing would campaign the ARX-06 in the 2023 IMSA SportsCar Championship season.[12]

The ARX-06 completed its first shakedown at Circuit Paul Ricard in July 2022.[13] It was followed by the car's first full test at Circuit de Nevers Magny-Cours on 16 & 17 July 2022.[14] The car was revealed on August 17, 2022. It was also announced that the car would use a hybrid powertrain, consisting of a 90° twin-turbocharged V6 internal combustion engine and standardized hybrid drivetrain components provided by Williams Advanced Engineering, Bosch and Xtrac, for maximum possible combined output of 671 hp (500 KW).[15] No 24 hour tests were conducted due to supply-chain issues.[16]
