Acura ARX-06 GTP
Built to the IMSA WeatherTech SportsCar Championship's new GTP regulations, the Acura ARX-06 debuted at the 2023 24 Hours of Daytona as a replacement for the ARX-05 that had run for five years under the previous DPi rule set. Acura continued its previous relationship with constructor Oreca to build the new car, which would debut in the hands of Meyer Shank Racing with Curb-Agajanian and Wayne Taylor Racing with Andretti Autosport; the teams would come roaring out of the gate by finishing 1-2 at Daytona.
The ARX-06 features a 2.4-liter, twin-turbocharged V6 engine, smaller than its predecessor but packing a powerful punch at over 670 horsepower. As with other GTP cars, the car weighs 1,030 kg and features a spec 50kW hybrid system.
