2025 Honda Civic Si Gets More Aggressive Styling, Improved Dynamics, Added Tech

The refreshed 2025 Honda Civic Si arrives this summer, with a more aggressive front design, revised taillights, improved dynamics and a host of new standard features, including heated front seats and Google built-in, as the brand continues to offer young driving enthusiasts more affordable high-performance.

“The best only get better at Honda, and this year we’re taking the Civic to an even higher level with our new and desirable Civic Si,” said Jessika Laudermilk, assistant vice president of Honda Auto Sales, American Honda Motor Co. “Civic Si is a performance icon in the sport compact segment, and the 2025 Civic Si continues that legacy as the most fun-to-drive Si we’ve ever offered to our customers.”

More Fun-to-Drive
The turbocharged 2025 Civic Si is one of the best performing cars in its class with an excellent power-to-weight ratio, lively handling and fun-to-drive feel – all while remaining comfortable for everyday driving. With this refresh, the sedan’s legendary fun-to-drive dynamics and class-leading ride comfort are further improved by body structure and suspension improvements.

The new SICE-compliant body makes this the most rigid Civic Si ever. New lower B-pillar and rear door sill supports increase torsional and bending rigidity.

To further amplify driver enjoyment and take advantage of the increased body stiffness, the Si suspension dampers have been retuned to match the increased body stiffness. And for drivers looking for maximum performance, sticky summer tires are now available as a factory option.

The performance of the standard Si rev-matching system has been enhanced by expanding its function to include downshifts from 2nd to 1st gear. The rev-matching system will “blip” the throttle when it detects all downshifts, perfectly matching revs with a lightning quick 430ms response time.

Civic Si delivers high levels of driver exhilaration and engagement with a precise short-throw 6-speed manual transmission, complemented by a light single-mass flywheel, which helps give the sport sedan’s high-torque VTEC 1.5-liter Turbo engine snappy throttle response. To maximize available traction during acceleration, the engine’s 200-horsepower and 192 lb-ft of torque is routed to the front wheels through a standard helical limited-slip differential.

Furthermore, Civic Si comes standard with larger brakes than the standard Civic Sedan, along with 235/40R18 all-season performance tires, or the aforementioned optional summer tires.

In addition to Normal and Sport driving modes, the Drive Mode system features an Individual mode that allows the driver to individually select engine response, steering assist level, and instrument panel display color parameters for a customized driving experience. Sport mode adds throttle response, decreases steering assist, deactivates the idle stop system, and changes the instrument accent lighting from white to red.

Exhilarating Design
The refreshed styling of the 2025 Honda Civic Si adds considerable attitude to the sport sedan with a more aggressive front fascia, new hex-pattern grille, and revised taillights with a darker appearance. Redesigned Civic Si-specific V-spoke 18-inch alloy wheels finished in matte black further enhance the sporty look.

Si features standard LED headlights and taillights, and sporty gloss black trim on its exterior mirrors and window surrounds. Functional aerodynamic aids unique to the Civic Si improve its performance over other Civic Sedan models. A front spoiler hidden under the vehicle and a gloss black rear spoiler add downforce to improve high speed stability.

The 2025 Civic Si is available for the first time in Urban Gray Pearl, which has become popular on other Honda models, including Accord and CR-V.

More Intuitive Tech
Intuitive technology has been integrated into the Civic Si with a focus on driver engagement, creating the most technologically advanced Si ever. In addition to the sport sedan’s 9-inch touchscreen, and wireless Apple CarPlay and Android Auto compatibility, the Civic Si gains the model’s first integration of Google built-in and new front USB-C ports, all standard. And to better support performance driving, the Si gets a new LED shift indicator light.

For additional comfort, the 2025 Civic Si exclusive body stabilizing sport seats are now heated, adding to features that include built-in head restraints, and prominent shoulder and lower thigh side supports. The 3-level front seat heater buttons are positioned within easy reach, alongside the high-quality knurled knobs of the climate control system.

Sport pedals and red contrast stitching on the doors, steering wheel, center arm rest, shift boot and leather-wrapped aluminum shift knob add a performance edge to the Si cabin. Racy red accents also adorn the signature metal honeycomb dash trim and red stitched “Si” logos dress its front seatbacks.

Civic Si comes standard with a moonroof and the best audio system in the class – a 12-speaker Bose premium sound system with Bose Centerpoint 2 technology and SurroundStage digital signal processing.

Civic Si Gets Google built-In
Standard on the refreshed Civic Si is the performance sedan’s first integration of Google. This includes apps like Google Assistant, Google Maps and more on Google Play for a personalized and connected driving experience with a complimentary 3-year unlimited data plan.

With Google Assistant, users can get things done while keeping their eyes on the road and their hands on the wheel. Talk to Google to easily call or text a friend, set reminders, or even change the temperature in the car. Users can also navigate to the next destination or look up what’s nearby. For example, Google Assistant enables users to set their destination in Google Maps using just their voice, with the route map then displayed in the instrument cluster.

Drivers can control their media by asking Google to skip to the next track or rewind a podcast using their favorite media apps with just their voice. Google Play enables users to download various 3rd-party apps for music, podcasts and audiobooks, just like they would on their smartphone.

Enhanced Honda Sensing
The Honda Sensing suite of safety and driver-assistive technologies is standard on all Civic models, with enhanced safety performance for 2025.

The upgraded Civic Si includes increased system visibility for motorcycles and bicycles for the Collision Mitigation Braking System (CMBS) with Pedestrian Detection, and smoother, more natural feeling to the functions of both Adaptive Cruise Control (ACC) and Lane Keeping Assist System (LKAS). Forward Collision Warning; Road Departure Mitigation (RDM) incorporating Lane Departure Warning (LDW); are standard. All Civic Sport models and Civic Si are equipped with blind spot information system with Rear Cross Traffic Alert.

Every Civic includes the proprietary Advanced Compatibility Engineering (ACE) body structure Honda designed to help protect occupants in a wide variety of frontal collisions, along with advanced supplemental restraint systems.

The 2025 Honda Civic Si goes on sale in early August with a starting price of $31,045. Optional high-performance summer tires that maximize grip and handling add just $300. That sounds like a seriously good deal, and I can’t wait to get some seat time with one. Stay tuned!
