Though still recognizable as a Civic, Honda designers pushed the enveloped a little farther with the latest redesign, adding a bolder front fascia that includes a chrome grille bar, optional LED headlight and lower air inlets.
The coupe takes the new design language even further than the sedan does, with a lower roof and slightly wider body to accentuate its shorter overall length, making it look more hunkered-down and aggressive than its four-door sibling. A further-lowered hip point for the front seat passengers also gives the coupe a more cockpit-like feel. The Coupe's longer doors get unique interior trim topped off by appropriately enormous grab-handles.
In addition to more room, passengers will also enjoy a redesigned cabin that includes a conventional gauge cluster and an available 7-inch touchscreen infotainment system that can run both Android Auto and Apple CarPlay. Soft-touch materials have been employed through the Civic's interior, giving the compact a more premium feel.
The 1.5L turbo-four has been tinkered with a bit, giving it a new output of 205 horsepower and 192 lb-ft of torque; that represents a 25-horsepower increase over the Sport hatchback and 31 over the standard tune of the 1.5L. As is tradition, the Civic Si is exclusively a front-wheel-drive model, and power gets to those wheels by way of a six-speed manual transmission outfitted with a helical limited-slip differential.
The honor of stand-out upgrade goes to the suspension, where Honda is employing two-mode adaptive dampers. The dampers are tied to the Civic Si's two drive modes ("Normal" and "Sport"), with the latter narrowing the tension and compression ranges of the adaptive system for sharper, more precise response.
The Si also gets bigger brakes, a beefier electric power steering system, stiffer anti-roll bars, upgraded bushings, some shared rear suspension components with the Type R, and a higher-flowing exhaust with a perpendicular muffler layout.
Inside, the Si also gets unique seats (well-bolstered and heated) and a short-throw shifter. Content-wise, the Si is essentially loaded. The larger touchscreen with Android Auto and Apple CarPlay is standard, along with a moonroof and premium audio.
Standard and Optional Equipment
The Si Sedan comes standard with A/C, Bluetooth connectivity, a premium audio system, Android Auto and Apple CarPlay, the aforementioned heated sport seats and most of the rest of the bells and whistles which are standard on Touring trims of the base Civic.
The only significant feature absent is navigation, but smartphone integration is meant to account for that. Summer tires are available at an additional cost. No other options are available.
All Civic models ship standard with advanced front, side, and side curtain airbags. The Civic's front and side airbags are equipped with a new venting technology that helps reduce the risk of injury for passengers "out of position" during the time of a collision.
Since the Civic Si is sold exclusively with a manual transmission, some of the semi-autonomous features available on the basic Civic Sedan and Coupe are unavailable.
Performance-oriented compacts that square off against the Honda Civic Si Coupe include the more powerful seven-generation Volkswagen GTI, the smaller MINI Cooper S, the Kia Forte Koup and the quirky Hyundai Veloster Turbo.
