The increased displacement contributes to a substantial 22-percent increase in peak torque, reaching 170 lb-ft. A key difference is the 0.4-liter larger displacement, which helps put the peak power at a more accessible 7000 rpm instead of the previous engine's 7800 rpm peak. The Civic Si produces 201 horsepower, up 4 horsepower versus the 2.0-liter engine it replaces. The Civic Si engine is a dual overhead cam (DOHC) all-aluminum, 2.4-liter inline 4-cylinder design that uses 16 valves, the i-VTEC system and a specially tuned high-volume intake manifold. With the i-VTEC "intelligent" valve-control system and new friction-reducing technologies and the Civic Si has prioritized exhilarating acceleration, improved fuel economy and low exhaust emissions. A range of innovative features help this new powerplant deliver a cutting-edge combination of performance, fuel efficiency, and low emissions.
