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. The SI was redesigned for the 2006 model. 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.
