197-hp, 2.0-Liter, DOHC i-VTEC® 4-Cylinder Engine
The 2.0-liter, dual-overhead camshaft K20Z3 engine produces 197 horsepower at 7800 rpm and 139 lb-ft of torque at 6100 rpm. Thanks to special Honda–developed performance technologies, such as the ultra-precise Drive-by-Wire™ throttle system, 3-rocker i-VTEC® variable valve timing, a cold-air intake and high-flow, low-heat exhaust manifold, the K20Z3 engine boasts a flat torque curve from 2000 rpm all the way to its race car-like 8000-rpm redline. Plus, the K20Z3's intake and exhaust system is quieter and less obtrusive when cruising at highway speed, but produces an aggressive, sporty sound at full throttle.
Close-Ratio 6-Speed Manual Transmission
The performance-oriented close-ratio 6-speed transmission is lightweight and compact, with a quick, precise shift action and solid, direct feel. Special features of this transmission include close gear ratios for first through fifth gears and a low 4.765:1 final drive, for faster acceleration, a stiffer cast-aluminum transmission case for reduced noise, carbon-faced single-cone synchronizers on fifth and sixth gears for enhanced shift feel and a low-ratio sixth gear for quieter, more fuel-efficient[1] highway cruising.

Drive-by-Wire™ Throttle System
The Drive-by-Wire™ system helps enhance the driving character of the Civic Si. With smart electronics connecting the throttle pedal to the throttle butterfly valve in the intake manifold, the engine response can be optimized to suit the driving conditions and to better match the driver's expectations.
Helical Limited-Slip Differential
Usually found only on high-performance and racing cars, the limited-slip unit helps give the driver more steering control and enhanced steering response when accelerating and cornering.
MacPherson Strut Front/Multi-Link Rear Suspension
The geometry of the Civic's MacPherson strut and multi-link rear suspension improves responsiveness and feedback that provide a good balance of taut performance and overall ride comfort.
