The 2023 IMSA Sports Car Championship will kick off an exciting new chapter in American endurance racing. A new set of rules for the high-end class, now called the GTP, has increased interest from major manufacturers, with Cadillac, Porsche, Acura and BMW poised to compete in iconic events including the 24 Hours of Daytona. Only a few dozen of the world’s top racers have had the chance to drive one of the new GTP race cars, but now there’s a chance to get the next best thing: the 2022 Acura ARX-05. This prototype runs on the GTP class’ predecessor, called the DPi, and is now being auctioned off at Bring a Trailer, which—like Car and Driver—is part of Hearst Autos.
The Acura ARX-05 DPi was introduced for the 2018 season and is based on the Oreca 07 LMP2 grade carbon fiber monocoque. Power comes from a twin-turbocharged 3.5-liter V-6 engine based on the production car’s J35 engine, a variation of which appeared in vehicles including the Acura MDX and Honda Odyssey. Unlike those family haulers, the V-6 ARX-05 produces 600 horsepower at 6500 rpm and sends that boost to the rear wheels via Xtrac’s six-speed sequential transaxle.
18-inch black Rotiform forged aluminum wheels, shod in Michelin Pilot Sport P2L tires, mounted to unequal-length control arm pushrod suspension. Brembo six-piston calipers combined with carbon brake rotors bring the ARX-05 down from a top speed of around 200 mph. The car also has a built-in air-jack system for quick pitstops. Open the butterfly doors and you’ll find a stripped-down focused cockpit with lots of buttons, a yoke-style steering wheel, a fire suppression system and six-point safety belts.
This particular ARX-05, chassis number seven, was built by Wayne Taylor Racing in December 2021 and is competing in the 2022 season, securing pole positions at Daytona, Laguna Seca and Road America and posting wins at Laguna Seca, Mid-Ohio, Watkins Glen, and American Street. Filipe Albuquerque and Ricky Taylor, who have each won the 24 Hours of Daytona twice, are the car’s full-time drivers, while Indy 500 winner Alex Rossi, three-time Le Mans winner Brendon Hartley and former F1 driver Will Stevens also spend time. . behind the wheel.
The car still uses the Konica Minolta blue, black and silver #10 livery. It is offered for sale by Honda Performance Development, which partners with privateer teams such as Wayne Taylor Racing to run high-end endurance racers. While old race cars occasionally appear for auction, it’s unusual to see one available for sale so soon after its last race, and it’s even rarer to find one that has amassed so many trophies. This unique piece of history makes for a stunning track day. With one week left until the auction ends on December 23, bidding is currently at $320,000.
