2025 Honda Civic Si Updated

America's Si now sits closer in content to its Canadian cousin.

After yesterday's 2025 Odyssey news, Honda is swinging to the sporty side with info on the updated 2025 Civic Si. As part of the Civic's line-wide refresh, the Si gains new looks and a broader feature list—though that list might look familiar to Canadians.

First up, the Si naturally benefits from the tweaked styling found on the regular Civic sedan. This includes the revised front bumper, new grille insert, and darkened taillights. The Si maintains the unique, gloss black rear lip spoiler of before, and now features unique 18-inch alloys; no longer are they simply a different shade of those found on the sedan. They do still come wrapped in 235-width rubber, in either all-season or—for an extra $300—summer form. Honda's Urban Gray Pearl, seen elsewhere in the lineup, is now available on Si as well.

Honda's engineers have added additional bracing around the B-pillar and rear door sills, improving torsional rigidity. To complement that, the team has retuned the Si's dampers.

Inside, the Si gains a 10.2-inch, fully digital instrument cluster (complete with shift lights), a 12-speaker Bose audio system, and the return of heated front seats. Well, gains them in the US; the Canadian-spec Civic Si has had them since this generation launched three years ago. We talked about all the market differences late last year.

Civic Si models now feature a 9.0-inch touchscreen. Again, not new to Canada, but what is new is the Google Built-In platform. American buyers get a complementary three-year data plan with it. The rest of the interior is familiar, with the red-accented, cloth bucket seats and other splashes of red throughout the cabin.

Honda hasn't messed with the turbocharged 1.5-liter engine, which still puts out 200 horsepower and 192 pound-feet of torque. The company has tweaked the automatic rev-matching however, which now works on 2–1 shifts. A helical limited-slip differential is once again standard.
