RACING AND STREET CARS
HPD Civic Si Race Car Prototype
Honda Performance Development (HPD) will debut the prototype for a new turn-key, race-ready version of the all-new 2022 Honda Civic Si, which features a turbocharged engine and 6-speed manual transmission. Created, developed and tested in-house by HPD engineers, the HPD Honda Civic Si race car draws upon HPD’s extensive production car and race vehicle engineering experience, including the development and incredible success of the 10th-generation HPD Civic Si TCA race car program.
Built from a body-in-white for SRO TC Americas, amateur touring car series, club racing and dedicated track day use, the race car foregoes a sunroof, sound proofing insulation, underbody coating and seam sealer to reduce weight and aid in roll cage installation. The car is then specifically modified for racing using a selection of HPD, and other performance and safety components.
Founded in 1993, HPD is Honda’s official North American motorsports company and the technical operations center for Honda’s high-performance racing programs, with products supporting multiple levels of motorsports, from karting to IndyCar, IMSA and SCORE off-road racing.
