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 0.90
g (8.8 m/s
2) 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, but with some tests posting times as quick as 6.3 seconds.
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), darker silver wheels, body-color grille, a deck lid spoiler, reversed red/black coloring on the secondary gauge cluster, 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, 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.
2009 refresh
Changes for the 2009 Si included a revised front bumper and grill, a new split five-spoke 17-inch wheel design, fog lamps and a USB MP3 player input as standard equipment, clear-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).
