2021 SEMA Show will open its doors on November 2nd, and, this year’s edition promises to be a very good show. As expected, Honda’s lineup for the Las Vegas show this year will be mostly about the new Civic Si.
A total of three different updates will be presented for the new sports sedan, including a racing prototype developed by Honda Performance Development (HPD). The car has been specially designed for SRO TC Americas, amateur touring car series, club racing and dedicated track day use.
2021 HPD Civic Si Race Car Prototype
What’s so special about the 2021 HPD Civic Si Race Car Prototype?
The new HPD Civic Si Race Car Prototype retains the essence of the Civic Si, but it received a major list of updates for both the exterior and the interior, but also for the drivetrain and the chassis.
Starting with the exterior, HPD wanted to give the Civic Si a more aggressive look.
It started with a race body-in-white and added front, side, and rear underbody spoilers.
A huge rear wing makes the car a lot more aerodynamic, and new bumper-mounted brake cooling ducts ensure better cooling.
The interior has also been modified to offer the best safety during racing. A roll cage was one of the first safety features added, but the new racing seats with HPD seat mounts also come equipped with a six-point racing harness. The car also gets a new aluminum steering wheel from OMP that can be quickly disconnected, a C125 center dash logger from Motec, and an MXP main display from AiM Technologies.
In its standard form, the 2022 Civic Si delivers a total of 200 horsepower. But the race car from HPD comes with a series of updates that will increase the final output. The only problem is that we do not know just yet to how much.
However, the updates announced by HPD include: a modified ECU, a new turbo-back dual-outlet exhaust, and a new, high-capacity aluminum radiator.
The car will also ride on a new set of 17-inch Momo wheels wrapped in 245/620-17 DHH Pirelli racing tires. The new wheels are combined with new 6-piston Superlite race calipers and 2-piece slotted floating rotors. As final updates, HPD is offering new Eibach race coil spring plus new inverted double-adjustable dampers from Bilstein.
A race car is supposed to be as light as possible, so the prototype from HPD foregoes a sunroof, soundproofing insulation, underbody coating, and seam sealer.
More details on this special Civic Si will be announced next week during its SEMA debut.
