Acura ARX-06

The Acura ARX-06 is a sports prototype racing car designed by Honda Racing Corporation USA, formerly known as Honda Performance Development (HPD), and built by Oreca. It is designed to the Le Mans Daytona h regulations, and competes in the GTP class in the IMSA SportsCar Championship since 2023. The car has a bespoke 2.4-liter twin-turbocharged V6 engine designated as the AR24e. The ARX-06 debuted alongside the BMW M Hybrid V8, Cadillac V-LMDh and Porsche 963 at the 2023 season opener of the IMSA SportsCar Championship at the Daytona International Speedway.

Background
In January 2021, Acura formally announced they would participate in IMSA's new GTP class in 2023 using an LMDh-compliant racing design. 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. 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.

The ARX-06 completed its first shakedown at Circuit Paul Ricard in July 2022. It was followed by the car's first full test at Circuit de Nevers Magny-Cours on 16 & 17 July 2022. 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). No 24 hour tests were conducted due to supply-chain issues.
