Underneath its hood, the front-wheel drive 2025 Honda Civic Si houses a turbocharged 1.5-liter four-cylinder engine that makes 200 hp and 192 lb.-ft. of torque. This is a performance variant and, as such, it is offered only with a six-speed manual gearbox. Adding to the behind-the-wheel experience are a sport-tuned suspension, a drive mode selector (Normal, Sport, and Individual), and a limited-slip differential. What’s more, the ’25 Civic Si achieves impressive fuel economy, with the EPA’s official estimates reporting 27 mpg in the city and 37 mpg on the highway.
The race-inspired ‘25 Civic Si gets a list of nice features that range from heated front sport seats to a moonroof. It also has proximity keyless entry, a leather-wrapped steering wheel and shift knob, push-button ignition, single-zone automatic climate control, sport pedals, striking red interior accents, a 10.2-inch digital driver interface, two front USB-C data ports, and a 60/40-split rear seatback with a folding center armrest. Its slick-looking exterior shows off a gloss-black decklid spoiler, a pair of chrome exhaust finishers, automatic LED headlights, LED daytime running lights and taillights, heated gloss-black side mirrors, and eye-catching 18-inch matte-black alloy wheels that can be outfitted with warm-weather performance tires as an upgrade. For those looking to do a bit of customization, the available accessories include front and rear underbody spoilers, illuminated door sills, and gloss-black exterior emblems.
The ’25 Civic Si is equipped with an array of safety features, most of which are part of the Honda Sensing suite. This comprehensive package bundles collision mitigation braking, road departure mitigation, adaptive cruise control with low-speed follow, lane keeping assist, forward collision warning, lane departure warning, blind-spot monitoring with rear cross-traffic alert, and automatic high beams. Beyond that, there’s a multi-angle rearview camera with dynamic guidelines, making it safer to parallel park or maneuver out of a parking space.
The 2025 Civic Si’s updated 9-inch touchscreen infotainment system features Google built-in (includes Google Assistant, Google Maps, and Google Play Store). Its other most prominent components are wireless Android Auto and Apple CarPlay, a Wi-Fi hotspot, SiriusXM satellite radio, HD Radio, a 12-speaker Bose audio system with 12 speakers, and Bluetooth technology for hands-free phone and audio streaming.
