2026 Honda Civic Si Sedan

The 2026 Civic Si maintains its singular trim as the performance-focused variant of the Civic Sedan lineup. Its exterior is distinguished by 18-inch matte-black alloy wheels, aggressive styling accents such as blacked-out trim and a reworked front fascia, sport seats visible through a performance-oriented cabin silhouette, and typically a power moonroof. The overall stance is lowered and more muscular compared to standard Civics, signaling its track-ready credentials while remaining street-sensible.

Under the hood, the 2026 Civic Si is powered by a 1.5-liter turbocharged inline-4 engine producing 200 horsepower at 6,000 rpm and 192 lb-ft of torque between 1,800-5,000 rpm. It pairs exclusively with a 6-speed manual transmission featuring rev-match control and a helical limited-slip differential for confident power delivery and driver engagement. This engine and gearbox combination keeps the Civic Si at the heart of the performance sedan segment.

The Civic Si delivers a sharp and engaging driving experience. With front-wheel drive and performance-tuned suspension, it balances everyday ride comfort with spirited handling. The manual transmission keeps the driver connected and in control, while drive modes (Normal, Sport, Individual) allow adjustments to steering feel and throttle response. Fuel economy is solid for a sport sedan, rated at approximately 27 mpg city and 37 mpg highway, making it practical for longer drives as well as fun runs.

Inside the Civic Si you’ll find seating for five with a focus on sporty refinement. Standard cloth upholstery is paired with red contrast stitching, aluminum sport pedals, and a leather-wrapped steering wheel. A premium Bose 12-speaker sound system raises the audio experience, and the cockpit design emphasizes driver focus. Larger trims add optional upgrades but even the base Si presents a well-equipped, intuitive interior.

Honda's full suite of safety technology, Honda Sensing®, comes standard on the Civic Si. Included are Collision Mitigation Braking System with Pedestrian Detection, Lane Keeping Assist, Road Departure Mitigation, Adaptive Cruise Control with Low-Speed Follow, Blind Spot Information System with Rear Cross Traffic Alert, and upgraded parking sensors and camera systems. This ensures that performance doesn’t come at the cost of safety.
