Honda Civic Si
The Honda Civic Si is a sport compact / hot hatch version of the Civic built by the Japanese automaker Honda. The Si (Sport Injected) trim was introduced for the third generation of Honda Civics in both Japan and North America. In Canada the trim became known as the SiR for the sixth and seventh generations, and the Si trim was equivalent to the USDM EX model.
For the Japanese and European markets, the Civic Type R was adopted as the high-performance variant of the Civic, starting with the EK9 hatch for Japan in 1996 and then with the EP3 hatch for Europe in 2001. In North America the Type R name has never been used for Civics, and the Si/SiR badge continues to signify the highest performance trim. The Civic Si contrasts with the more track-oriented and spartan Type R, which has less sound deadening and amenities in return for better performance, and has been positioned as more of a full-featured sport trim, featuring luxury options such as a sunroof and a seven speaker audio system.
1984–87 3rd generation Si
1989–91 4th generation Si
1992–95 5th generation Si
1996–2000 6th generation Si
2002–05 7th generation Si
2006–2011 8th generation Si (FA5/FG2)
The Si was redesigned for the 2006 model year along with all other Civic trims, bringing about significant changes from the previous generation. The car comes with a 2.0-liter K20Z3 i-VTEC engine that produces 197 hp (147 kW; 200 PS) and 139 lbf·ft (188 N·m) of torque, while also including a 6-speed manual transmission with a helical limited slip differential. Forty percent stiffer spring and dampening rates from the non-Si trims and stiffer sway bars have bolstered the Civic Si's handling with the car achieving 0.90g (8.8 m/s2) of lateral acceleration on the skidpad. It is also the quickest Civic Si off the line, with a factory 0–60 time of 6.7 seconds according to Honda[Standard features include a moonroof, a seven-speaker 350-watt sound system, 17-inch alloy wheels with 215/45R17 Michelin all-season tires, and key-less trunk access.
In Canada, the Acura CSX Type-S was offered in 2007, borrowing the engine and drivetrain from the Civic Si but offering additional luxury options such as leather seating. The CSX features similar front and rear fascias to the JDM Civic, but with slight differences—the CSX has a crease running along the center of the hood and front bumper, whereas the JDM does not.
The 2007 model changes for the Civic Si include the addition of the Si trim for sedans, vehicle stability assist (VSA) (not available on Canadian models. The 2010 and 2011 Canadian models had VSA), darker silver wheels, body-color grille, a deck lid spoiler, reversed red/black coloring on the odometer, and Si-embroidered front floor mats. The introductory price of the Si Coupe increased by $800 to the MSRP of $21,090.
For the 2008 model year, the Civic Si received minor tweaks that include even darker wheels than the 2007 model and a new shift boot with red stitching. Mechanical changes included a new tire pressure monitor system, a new rear upper arm that decreases the amount of rear camber, and a lowered spring rate for the coupe to match the sedan. This was also the first year Canada sold the Civic Si Sedan.

Civic Si Sedan
Honda introduced the Civic Si Sedan for North America in 2007; previously, only the Japanese market had been offered Si Sedans. Debuted at the Chicago Auto Show, the Si sedan concept featured larger 18-inch alloy wheels than its coupe counterpart, along with 4-piston Brembo brakes, and large cross drilled brake rotors. The production version lacked such concept accouterments, and the Si Sedan is mechanically almost identical to the coupe. Performance of the Si sedan is roughly equivalent to the Si coupe; the sedan's 60-pound (27 kg) weight increase is offset by a slightly more balanced front/rear weight distribution (60/40 for the sedan versus 61/39 for the coupe).
Civic Mugen Si Sedan
The 2008 model year also brought into production the limited-edition 2008 Civic Mugen Si Sedan, which was announced at the 2007 SEMA auto show The Mugen sedan came only in Fiji Blue Pearl, and featured a higher-flowing cat-back exhaust, track-tested sport suspension, an exclusive Mugen grill, an exclusive shift knob, Mugen Si badges on the exterior and interior, Mugen forged GP wheels, and a Mugen body kit custom designed for the American trim. Production was limited to only 1000 units, and the car carried an MSRP of $29,500. Even with additional features, the road tests at Shannonville showed the performance of the Mugen Si to be roughly equivalent to the standard Civic Si coupe.
2012 Ninth generation Si (FB6/FG4)
The 9th generation Civic Si comes in a Coupe and a Sedan. The most notable difference from the previous generation is the engine upgrade. The Civic Si now features a K24Z7, 11.0:1 Compression, 2.4L 201 hp engine (a higher compression version of the one found in the Honda CR-V) capable of producing 170 lb·ft (230 N·m) of torque. The peak torque can be achieved at a much lower rpm as well, 4400 rpm vs the previous 6000 rpm. Due to the increased stroke implemented to increase midrange torque, the redline has been reduced to 7000 rpm, with a fuel cut at 7200 rpm. Retained is the 6 speed manual transmission with a slightly different final drive ratio. An automatic transmission is not available. The wing spoiler found on the previous generation is replaced by a slightly more subtle deck-lid spoiler. The interior of the car gets a slight refresh as well, in the form of a rev limit indicator and a power meter, displayed in the all-new i-MID (intelligent Multi-Information Display). While the sway bars are noticeably slimmer than the previous generation's (18.0/15.0, down from 28.0/17.0 (F/R in mm)), the chassis is more rigid, the result of an increased amount of high-strength steel. This also results in lighter weight compared to the previous model. It is also notable that the vehicle remains the same size as the outgoing model. Still included is the Helical LSD (Limited Slip Differential) found on the previous model.
Announced at the 2011 SEMA Show in Las Vegas a HFP (Honda Factory Performance) Version of the civic was made available in a limited production of dealer installed performance parts which included:
- Lowered Suspension
- 18" HFP Diamond Cut Alloy Wheels
- Michelin Pilot Super Sport 18x215x40
- Full body Kit including front, rear and side skirts
- HFP Badging
- HFP Branded Floor mats
In Canada the production was limited to 400 (200 Black Coupes, 200 White Coupes). In the USA the production was limited to 500 available in all of the colors Honda Offered the Civic Si Coupe in.
