Under the hood lies an enhanced 1.5-liter turbocharged four-cylinder engine good for 200 horsepower and 192 lb-ft of torque. Peak hp kicks in at 6,000 rpm while peak torque is between 1,800 and 5,000 rpm. A short-throw six-speed manual with rev-matching from the Type R, the sole gearbox option, routes power to the front wheels through a limited-slip diff. Honda says the manual has 10 percent shorter throws and a more rigid shift lever mounting bracket.
Engineers added a dual-coil silencer exhaust system capable of increasing exhaust flow by 27 percent compared to the Civic Touring. An Active Sound Control system improves engines noises inside the cabin. Additional upgrades include a new single-mass flywheel that’s 26 percent lighter than the previous Si’s dual-mass unit. Inertia has been reduced by 30 percent for better throttle response.
The new rev-matching system comes straight from the Type R. When in Sport mode, driver’s will get a “blip” when the system detects a downshift. Better handling is achieved by an 8 percent increase in torsional rigidity and a 13 percent increase in bending rigidity. Rear spring rates are 54 percent stiffer compared to the standard Civic. Steering is enhanced by 60 percent thanks to a torsion bar.
