205-Horsepower, 2.4-Liter, 16-Valve DOHC i-VTEC® Engine
The 2.4-liter, dual-overhead camshaft NP2 engine produces 205 horsepower at 7000 rpm (SAE net) and 174 pound-feet of torque at a low 4400 rpm (SAE net).
6-Speed Manual Transmission
The performance-oriented, close-ratio 6-speed transmission is lightweight, compact and has a solid feel. It includes special features like close ratios for 1st through 5th gears, and a low final drive for faster acceleration. A stiff cast-aluminum transmission case helps reduce noise, while carbon-faced single-cone synchronizers on 5th and 6th gears enhance the shift feel. Finally, a low-ratio 6th gear provides a quieter and more fuel-efficient mode for highway cruising.

Textured Aluminum Pedals
The Civic Si pays respect to its racing heritage with drilled-aluminum pedals.
Helical Limited-Slip Differential
Usually found only on high-performance and race cars, the limited-slip unit helps give the driver more steering control and enhanced steering response when accelerating and cornering, even when the road surface is less than ideal.
MacPherson Strut Front/Multi-Link Rear Suspension
The MacPherson strut and multi-link rear suspension improves feedback and provides a great balance of taut performance and overall ride comfort.
Sequential Rev-Limit Indicator
Every shift counts. The sequential rev-limit indicator displays lights that indicate rising engine rpm. When you find the right rev range, an i-VTEC® light also flashes on, accompanied by more power from the engine.
