After the overwhelmingly positive reaction to the racing Civic Si concept shown at last year’s Performance Racing Industry show, Honda Performance Development (HPD) is pleased to launch the HPD Civic Si Race Car program. HPD plans to build, sell and support a turnkey, current-gen Honda Civic Si race car to registered Racing Line members, and create additional opportunities in racing series such as the 2019 Pirelli Challenge TCA, Canadian Touring Car Championship (CTCC) Touring Class, SCCA T3, and NASA H2 classes.

HPD Civic Si Profile

As last year’s Pirelli World Challenge TCA champion race car driven by Tom O’Gorman, the Civic Si is a dynamic and proven racing platform that is affordable and fun to drive. Like HPD’s other Civic touring car race cars, the HPD Civic Si race car will be built from the HPD Civic Body-in-White, which debuted at the 2016 SEMA show. HPD will include a full complement of race-tested performance parts used in running the car during the past two seasons in the Pirelli World Challenge, as well as technical support and documentation through its HPD Racing Line program.

HPD CIvic Si Rear

The complete race car is priced at $52,500 (excluding delivery from Santa Clarita, CA) and includes an installed roll cage, HPD-developed and homologated parts including engine, suspension, exhaust, and electronics packages.
