Model History

2022-Present

Current Generation

Available only as a sedan, this Si is based on the 11th generation Civic. Honda refreshed the Civic for 2025. Thanks to suspension tweaks, most Civics get a ride comfort improvement but not the Si. The stiff and choppy ride can send big jolts into the cabin on rougher roads. The sporty Si comes only with a six-speed manual transmission and a 200-hp turbo engine. The precise shifter is a delight to operate. The cabin is relatively roomy, but the car's low-slung stance makes it awkward to get in and out. The Civic features a less cluttered interior and a simpler infotainment system. The touchscreen infotainment system is very easy to use. The Si gets standard BSW and RCTW which are available only on the top Civic trims. The high-performance Type R with a 315-hp, 2.0-liter turbo engine returns for 2023.

2017-2021

2017 Redesign Year

Redesigned for 2017, the Civic Si, available as either a coupe or a four-door sedan, uses a powerful 205-hp, 1.5-liter four-cylinder turbocharged engine that revs easily, sounds invigorating. The high- performance Type R with a 306-hp, 2.0-liter turbo engine also debuted in the U.S.. The standard six-speed manual transmission has ideally spaced gear ratios and shifts crisply. It gets a commendable 32 mpg overall in our tests. However, the Si falls short as a sports sedan. While the handling is capable, it is uninspiring and lacking in finesse, and the steering lacks feel and response. The ride is very stiff and noise levels are extremely high. The Honda Sensing suite of safety and driver assisted technologies became standard for 2020.

2012-2016

2012 Redesign Year

Available as either a coupe or a four-door sedan, the Civic Si uses a powerful 201-hp, 2.4-liter four-cylinder engine that revs easily, sounds invigorating, and delivers a commendable 29 mpg overall. The six-speed manual transmission has ideally spaced gear ratios and shifts crisply. However, the Si falls short as a sports sedan. While the handling is capable, it is uninspiring and lacking in finesse, and the steering lacks feel and response. The ride is very stiff and noise levels are extremely high. The Si also feels insubstantial, with subpar interior quality.

2006-2011

2006 Redesign Year

The Civic Si is a sporty coupe based on the top-rated small Civic sedan. It comes with a smooth, powerful 197-hp 2.0-liter four-cylinder engine that revs easily and sounds invigorating. The five-speed manual transmission is replaced by a six-speed manual. It has ideally spaced gear ratios and shifts crisply. Handling is fairly nimble with tenacious tire grip. But the electric steering feels a bit vague and short on feedback. Its response is not linear, detracting from the car's agility and sporty character. The ride is stiff and choppy and road noise is pronounced. The Si manages to deliver spirited acceleration as well as commendable fuel economy.
