Acura have released the first official photos and technical details of their upcoming ARX-06 prototype which will make its debut in the upcoming LMDh class at next January’s 24 Hours of Daytona alongside cars from Porsche, Cadillac and BMW.

The team have chosen to continue their partnership with ORECA into the LMDh era, building their new challenger around the French chassis manufacturer’s next-gen LMP2 chassis, which will also underpin the future Alpine LMDh offering.

The chassis is clothed by a bodyshell designed by the Acura Design Studio in Los Angeles with inputs coming from both HPD and ORECA. The overall car has kept much of the design language from Acura’s current DPI racer, although the loosening of the bodywork regulations for this new class has allowed the team to further sharpen and stylise their concept.

A brand new 2.4 litre twin-turbo V6 will be the beating heart of Acura’s new race car, a powerplant which the team promises will rev all the way up to an ear-splitting 10,000rpm. The engine will work alongside a spec hybrid system developed by Bosch and Williams Advanced Engineering as per the LMDh regulations, with the HPD team designing the internal combustion engine to make the most of this system.

Acura will make two cars available for the LMDh’s inaugural season in 2023, both competing in IMSA’s GTP class with established and highly successful customers, Wayne Taylor Racing and Meyer Shank Racing, both of whom are currently running Acura’s DPI cars to first and second in the IMSA championship with only a round left to run.

While the Japanese manufacturer has made no indication that it plans to run in either the FIA WEC or the 24 Hours of Le Mans, both its current customer teams have expressed an interest, although this is understood to not be an option until 2024 at the earliest.
