Honda Civic Si

1987 Honda Civic Si

Honda first adopted the Si badge for the Japanese domestic market (JDM) third-generation Civic in November 1984. Japanese and European Si's received a 120 PS (88 kW; 118 hp) DOHC engine, while US and Canadian cars were powered by a 91 hp (68 kW), 12-valve SOHC engine. The Civic Si also appeared in New Zealand and Australia in 1987, with specifications similar to those of the American-market Si.

Initially, the Civic Si hatchback was absent from the 1988 Civic lineup, with only the CRX Si offered this model year. In 1989, however, the Civic Si hatchback was reintroduced to the US market.

The 1992-1995 Civic Si model featured disc brakes, a power moonroof with tilt, cruise control, a dashboard clock, a 9,000 rpm tachometer with a 7,200 rpm redline, plastic wheel covers on 14 inch wheels, power side mirrors (body coloured, beginning in 1993), body-coloured door handles, and a 125 hp (93 kW) 1.6 L single-overhead cam D16Z6 VTEC engine with manual transmission. It enabled the car to hit 0–60 mph (97 km/h) in 7.5 seconds and a quarter-mile time of 16.3 seconds at 86 mph (138 km/h).[3] VTEC activated on the intake side and not the exhaust side, which was the result of the spark plug blocking the area where the cam follower would be. In 1994, rear speakers and optional ABS were also added.

1999 Honda Civic Si

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. After this brief hiatus, the Civic Si reappeared for 1999, available as a coupé only. With the adoption of the VTi badge in Europe and the SiR and Type R badges in Japan for the sports variants of Civics, the Si became primarily a US-specific badge, a branding trend that would continue in subsequent Civic generations.

The EP3 Civic Si of the USA and EP3 Civic SiR of Canada was marketed as the North American versions of the European EP3 Honda Civic Type R, manufactured in Swindon, England. Unlike other generations of the Civic Si, it does not share a body style or interior with the regular USDM Civic (offered only in sedan and coupé forms)

2002-03 Honda Civic Si (US)

The Civic Si continued to be the sportiest Civic on offer in North America, although the badge was used on a somewhat sporting model in Europe (where the Type-R sits atop the lineup). The US model has a 197 hp (147 kW; 200 PS) version of the K20 engine (K20Z3), a 6-speed manual transmission, sport seats, and different styling. The Civic Si coupe debuted a few months after the initial launch of the 2006 models, with the Civic Si sedan following in 2006 (2007 in Canada). The K20z3 engine found in the 8th generation civic si boasts an impressive revolution limit of 8300 RPM, a VTEC engagement point of 5800 RPM, and achieves peak horsepower at 7800 RPM.[4] In addition to being built at Honda's Alliston, Ontario plant, the car was also manufactured at Sumaré, São Paulo, Brazil by Honda Brazil from January 2008. A special version of the 8th generation civic Si, known as the Mugen Si debuted in 2008 and featured a slightly different body kit, a more free flowing exhaust, updated suspension, 18 inch forged wheels, a larger rear wing, and different interior components.[5] The Mugen Si was available as a 4 door only, exclusively in Fiji Blue Pearl and features front and rear MUGEN emblems. The suspension featured on the Mugen Si gives the vehicle a 0.6 inch lower ride height as well.[6] .

2012 Honda Civic Si Coupe (FG4 (US); pre-facelift)

The ninth generation was the first generation to use a different engine than other models of the Honda Civic. The ninth 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.[7] 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 7,000 rpm with a fuel cut at 7,200 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.[8] 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.

The 2017 Honda Civic Si (tenth generation) was revealed in a live YouTube broadcast on April 6, 2017. It is powered by a more powerful version of the 1.5L turbocharged four-cylinder engine used in other Civics. It went on sale during May 2017 in the United States as either a coupe or sedan. It is based on the 10th generation Honda Civic EX-T, both the sedan and coupe variants. A direct injected 1.5 liter turbocharged engine utilizes dual variable cam timing (dual VTC) to produce 205 horsepower and 192ft-lb of torque. Peak horsepower is reached at 5700 rpm, while low end maximum torque is available between 2,100 and 5,000 rpm. The suspension has been tuned and stiffened over the standard Civic.

The body includes highly upgraded chassis and drive components, including a dual-pinion adaptive electric power steering system with variable ratios, sport-tuned suspension, an adaptive damper system, a helical limited-slip differential, larger front brake rotors (12.3-inch) and wider 235/40 R18 tires. In addition to adaptive dampers, suspension upgrades over the Civic EX-T include stiffer spring rates, more rigid stabilizer bars (+7 percent front, +26 percent rear), and solid front and rear compliance bushings, the latter shared with the track-focused Civic Type R.
