Honda Civic Si

|Body and chassis|
The Honda Civic Si is a sport compact trim of Civic by Honda. The Si (Sport Injected) trim was introduced for the third generation of Honda Civics in both Japan and North America. In Canada and elsewhere 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 Honda-branded vehicles (only the Acura Integra), 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. The Civic Si has been positioned as more of a full-featured sport trim, featuring luxury options such as a sunroof and a seven speaker audio system.
The Honda Civic Si was not sold in the US during model years 1996-1998. It started production again for the 1999 and 2000 model years. All Honda Civic Si models from 1999 and 2000 were manufactured with a Denso type A/C compressor.

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. Some new features include a moonroof, a seven-speaker 360-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.
In Europe the Si and the Type-S models were offered, with the Type-S in the 3 door configuration the Type-R is based on and the Si in the 5 door, but bother going without the 198bhp 2.0L engine. No saloon version was offered in Europe.
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 grille, 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. Testing by Car and Driver magazine determined that the acceleration of the Mugen Si was roughly equivalent to that of the standard Civic Si coupe.
Changes for the 2009 Si included a revised front bumper and grille, a neclear-lensed and amber bulbs for the front and rear turn signals, a clear instead of red third brake light in the rear spoiler, and chrome trunk trim for the sedan. Several new colors were also introduced, such as Redline Orange Pearl, Dyno Blue, Polished Metal Metallic, and Crystal Black Pearl, replacing the previously similar colors.
The 2010 Civic Si saw no significant changes, save for a black engine cover (instead of silver).

The 9th generation Civic Si is available as a Coupe and as a Sedan. Honda uses a new 2.4L K-Series (K24Z7) which has increased displacement through longer piston stroke than the K20Z3 from the 8th generation Civic Si, yet the K24Z7 retains the 11.0:1 compression used in the K20Z3. The K24Z7 produces 201 hp and 170 lb·ft (230 N·m) of torque. Honda retuned the exhaust system in early 2014, increasing the output to 205 hp and 174 lb·ft (236 N·m) of torque. The K24Z7 is different than the K24Z7 found in the Honda CR-V; the CR-V has lower compression and a different, efficiency-oriented VTEC design.
The redline of the K24Z7 is 7000 rpm with a fuel cut at 7200 rpm. A 6 speed manual transmission with a helical LSD (Limited Slip Differential) is still offered as the only available transmission option for the Civic Si. The wing spoilers are different from the 8th generation, and the interior of the car received slight updates with the addition of a rev limit indicator and a power meter displayed in the new i-MID (intelligent Multi-Information Display). Sway bars have been changed to F18mm/R15mm from the F28mm/R17mm in 8th generation. The chassis is more rigid, and the curb weight is slightly lower than the 8th generation.
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 sized in 215/40-18
- 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. After the 2015 model year Honda did not produce the Civic Si for 2016, citing poor sales.  However, the 2017 Civic Si has been announced. 
In Insurance Bureau of Canada's report on top 10 most stolen vehicles in 2005, 2000 Honda Civic Si 2-door, 1999 Honda Civic Si coupe, 1994 Honda Civic Si 2-door Hatchback, 1995 Honda Civic Si 2-door Hatchback are listed as ranks #1, #2, #5, #8 respectively. However, it should be noted that the sixth and seventh generation Civic Si was badged as a Civic SiR in Canada. The Canadian Si was equivalent to a US market EX.
