     Aug 29 2006 - The 2006 Honda Civic establishes new segment standards for safety, technology and performance. 

        Clean and efficient i - VTEC(TM) engine technologies deliver more power than ever before while still achieving an EPA-estimated fuel economy rating of 40 miles per gallon. In keeping with Honda's "Safety for Everyone" initiative, the Honda Civic features advanced standard safety equipment including side curtain airbags, front side airbags and the Advanced Compatibility Engineering(TM) (ACE(TM)) Body Structure, regardless of price or trim level.

          High revving power, quick shifting precision and tenacious grip describe the Civic Si powertrain. The 16-valve 2.0-liter engine uses Honda's i-VTEC "intelligent" valve control system that combines Variable Timing Control (VTC) to continuously adjust camshaft phase with Variable Valve Timing and Lift Electronic Control (VTEC) that adjusts valve lift, timing and duration. Combining these two systems results in impressive horsepower and high torque with good fuel economy and low exhaust emissions. The Civic Si utilizes VTEC and VTC for both intake and exhaust valve control to produce 197 horsepower (11) at 7800 rpm and 139 lb-ft. of torque (11) at 6200 rpm. The air intake system and the exhaust system are tuned to provide a deep sound and resonance, adding a level of performance feedback more commonly found on racecars. Further refinement is found in the drive-by-wire throttle body for smooth acceleration response and a chain driven balancer unit in the oil pan minimizes engine vibration.

The Civic Si is available exclusively with a 6-speed manual transmission. Designed to be exceptionally compact and lightweight, this 6-speed has also been engineered to shift with extremely short and precise throws. A final drive ratio of 4.76:1 promotes aggressive acceleration while a tall 6th gear provides for relaxed highway cruising. The short-throw clutch has an innovative torsion mechanism that considerably reduces noise. Multiple synchronizers are utilized, and 5th and 6th gears feature single carbon synchronizers for a direct shift feel.
