- The ARX-05 competed in the 2022 IMSA championship, powered by a 600-hp twin-turbo V-6 mounted to a carbon-fiber monocoque and sending the power exclusively to the rear wheels.
- Finding a recent race winner up for sale so soon after its competitive career has ended is a rare occurrence, especially since the car is offered directly by Honda Performance Development.
- The ARX-05 is up for sale on Bring a Trailer, with the online auction ending on December 23.
The 2023 IMSA SportsCar Championship will kick off an exciting new chapter in American endurance racing. A new set of rules for the top class, now called GTP, has brought increased interest from major manufacturers, with Cadillac, Porsche, Acura, and BMW all set to compete in iconic events including the 24 Hours of Daytona. Only a few dozen of the world's top drivers will have the chance to pilot one of the new GTP race cars, but now there is the opportunity to get the next best thing: a 2022 Acura ARX-05. This prototype ran in the predecessor to the GTP class, called DPi, and is now up for auction on 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 around an Oreca 07 LMP2-class carbon-fiber monocoque. Power comes courtesy of a twin-turbocharged 3.5-liter V-6 that is based on the J35 production-car engine, variations of which appear in vehicles including the Acura MDX and the Honda Odyssey. Unlike those family haulers, however, the ARX-05's V-6 churns out 600 horsepower at 6500 rpm and sends that shove to the rear wheels through an Xtrac six-speed sequential transaxle.
The black 18-inch Rotiform forged aluminum wheels, shod in Michelin Pilot Sport P2L tires, are mounted onto an unequal-length control arm pushrod suspension. Brembo six-piston calipers combine with carbon brake rotors haul the ARX-05 down from a top speed of around 200 mph. The car also has a built-in air-jack system for rapid pitstops. Open the butterfly doors and you'll find a stripped-out, focused cockpit with an abundance of buttons, a yoke-style steering wheel, a fire suppression system, and a six-point harness.
This particular ARX-05, chassis number seven, was built by Wayne Taylor Racing in December 2021 and competed in the 2022 season, securing pole positions at Daytona, Laguna Seca, and Road America and notching victories at Laguna Seca, Mid-Ohio, Watkins Glen, and Road America. Filipe Albuquerque and Ricky Taylor, who have each won the 24 Hours of Daytona twice, were 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 spent time behind the wheel.
The car still wears the blue, black, and silver #10 Konica Minolta livery. It's being offered for sale by Honda Performance Development, which works closely with privateer teams such as Wayne Taylor Racing to run top-class endurance racers. While old race cars occasionally come up for auction, it's unusual to see one available for sale so soon after its final race, and even rarer to find one that collected so many trophies. This unique piece of history would make for a head-turning track day. With a week remaining until the auction ends on December 23, bidding is currently at $320,000.
