Based on the 11th-generation Civic Sedan, the turbocharged 2022HondaCivic Si sets a new benchmark for sport compact sedans, with improved dynamic performance and an updated manual transmission now featuring the rev-matching system from the Civic Type R.
The 2022HondaCivic Si is powered by an updated high-output VTEC 1.5-liter turbocharged 4-cylinder engine with usefully broader power curves than before. The engine’s peak torque of 192 lb.-ft. of torque at 1800-5000 rpm (SAE net) now arrives 300 rpm sooner for a quicker punch off the line and out of tight corners. Performance is also improved at the top of the tach where the engine maintains more output between its 200-horsepower power peak at 6000 rpm (SAE net) and its 6500 rpm redline.
Improving the sound of the engine is a new dual-coil silencer exhaust system that increases exhaust flow 27 percent compared to Civic Touring. To complement the engine’s natural exhaust note inside the cabin, Civic Si uses an improved Active Sound Control system that can produce high-quality sound over a wider range of engine rpm.
A new single-mass flywheel is 26 percent lighter than the dual-mass unit used in the previous Si. The flywheel’s 30 percent reduction in inertia gives the 1.5-liter turbocharged engine a snappier throttle response for an even sportier driving experience, while also improving drivability. To maximize available traction when accelerating, power is routed to the front wheels through a standard helical limited-slip differential.
Equipped exclusively with a manual transmission, Si’s 6-speed has been updated for enthusiast drivers with improved shift feel and 10 percent shorter throws. A new, more rigid shift lever mounting bracket and a new leather-wrapped aluminum shift knob similar to the Civic Type R’s contribute to the improved feel.
For the first time, Civic Si features a rev-matching system directly from the Civic Type R. With the same 430 m/s response time as Civic Type R in Sport mode, the new rev-matching system will “blip” the throttle when it detects a downshift, quickly and perfectly matching revs.
The net result of these changes is a notably richer and more engaging driving experience, made even more so with substantial dynamics improvements.
