All-New 2022 Honda Civic Si – Powertrain & Handling

October 22nd, 2021 by

The best-handling, best-equipped and most fun-to-drive Civic Si ever is coming to Honda dealers later this year to entice a new generation of young driving enthusiasts.

Based on the all-new 11th-generation Civic Sedan, the turbocharged 2022 Civic 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.

More Responsive Powertrain

The 2022 Civic 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.

Sharper Handling

2022 Honda Civic Si

In terms of body stiffness, this is the most rigid Civic Si ever, with an 8 percent increase in torsional rigidity and a 13 percent increase in bending rigidity compared to the outgoing Si. Like the 2022 Civic Sedan, the new Civic Si also benefits from a 0.5-inch wider rear track for additional stability, and a 1.4-inch longer wheelbase for a smoother ride, as well as greater high-speed stability. The Si’s 107.7-inch wheelbase is the longest in its class.

To maximize handling and driver enjoyment, spring rates are 8-percent stiffer in front and 54-percent stiffer in the rear compared to Civic Sedan. New dampers also have been tuned specifically for the Si. The front MacPherson struts feature reinforced upper mounts to handle the increased cornering loads, and thicker front (27 mm hollow) and rear (18 mm solid) stabilizer bars compared to Civic Sedan to minimize body roll.

To improve stability, the front compliance bushings, sourced from the Civic Type R, are 79-percent stiffer than the Civic EX Sedan. Stiffer rear compliance bushings, upper arms and lower B-arms are also sourced from Type R. Steering feel is improved using a 60-percent stiffer torsion bar connecting the steering shaft to the steering rack pinion gear.

Civic Si features larger brakes than the standard Civic Sedan. Oversized 12.3-inch front rotors (+1.2-inches vs. Sedan), and 11.1-inch rear rotors (+0.9-inch vs. Sedan) are standard along with 235/40R18 all-season performance tires. For drivers looking for maximum performance, summer tires will be available as a factory option.

In addition to Normal and Sport driving modes, Si’s updated Drive Mode system now features an Individual mode that allows the driver to individually select engine response, steering effort, and instrument panel display color parameters for a customized driving experience. Sport mode adds throttle response, decreases steering assist, deactivates the idle stop system, allows drivers to select rev match on or off, and changes the instrument accent lighting from white to red.
