Like all 10th generation Civic models, the new Civic Si benefits from Honda's vehicle packaging expertise. The Civic interior – with its spaciousness, smart design, comfortable fit and intuitive controls – has always been a competitive strength. And in the Civic Si, that interior architecture has a clearly defined sporting flavor, with bold black seating with red accent stitching, racing inspired alloy pedals, leather-wrapped steering wheel, and red themed instrumentation. Performance driving is supported with selectable real-time information, including turbocharger boost gauge, G-Force gauge and Rev-limit indicator.

With 88.6 (Coupe) and 95.0 (Sedan) cubic feet of passenger cabin volume, the Civic Si Coupe and Si Sedan top the compact-class for interior space and comfort, with class-leading headroom, legroom, shoulder clearance and side head clearance. Rear-seat passengers will appreciate newly shaped front seats with a narrower upper profile (in the shoulder area) and smaller integrated head restraints that lend the rear cabin a more open, airy feel. In keeping with the Civic Si's sporting mission, both the Coupe and Sedan have special high bolstered front seats that enhance lateral support during aggressive cornering.

Both the Civic Si Coupe and Si Sedan offer roomy trunk utility. The Civic Si Coupe has a trunk capacity of 11.9 cubic feet and the Civic Sedan has a trunk capacity of 14.7 cubic feet – both among the largest in the competitive class. Spacious enough to easily accommodate four large golf bags, the trunk area in both Coupe and Sedan is easy to access and use, with a low lift-over height and wide opening. Both Civic Si models feature a 60/40 split and folding rear seatback.

Interior Materials The new Civic Si interior takes the refinement of Honda's most affordable sedan in an aggressive, sporting direction. The Civic Si interior features Si-exclusive front sport seats with red stitching, including stitched Si logos. The red sport stitching carries through to the doors, leather-wrapped steering wheel, shift boot, and aluminum and leather shift knob. The Si interior also features unique red instrumentation and audio system illumination. Alloy sport pedals, carbon-look accents and titanium silver details highlight the Si's performance attitude.

Interior Design In both Coupe and Sedan, the new Civic Si interior blends a dynamic and wide layout with smoothly integrated technology features and-high quality materials. Handsome new instrumentation with a red Si performance theme is paired with a full-color 7-inch Driver Information Interface (DII) display and a 7-inch color touchscreen Display Audio system with a clean and sleek appearance.

The Civic has always been known for its user-friendly design, and the new generation Si builds on that reputation. Like the other 10-generation Civic models with completely redesigned packaging, the Civic Si has a more open roomy feel. A redesigned instrument panel made possible a more compact climate control system that opens up added knee room, and the tandem distance (distance between the front and rear seat hip point) is increased 4 inches in the Si Coupe and by 1.8 inches in the Si Sedan versus the previous generation Civic Si models.

All important systems and controls in the Civic are positioned within easy reach of the driver. Controls for the systems used most frequently – audio, cruise control, Bluetooth®3 HandsFreeLink® and intelligent Multi-Information Display – are conveniently positioned on the Si's leather-wrapped steering wheel. The main instrumentation is an easy-to-read analog design, supplemented with digital and graphic displays. Typical of Honda interior design, the soft-touch switchgear of the Civic is engineered to deliver a high-quality feel and positive action.

Interior Color The Civic Si's performance oriented interior is offered in black fabric with black/gray carbon-pattern inserts on the front seats, highlighted by red stitching. Carbon-look trim and titanium silver painted accents adorn the instrument panel.

Front Seats The Civic Si's unique front bucket seats are designed to provide welcoming support for a wide range of body types, along with enhanced secure lateral support for aggressive cornering. Compared to the seats in other Civic models, the Si special seats feature added internal side structures in the base and seatback to better support the expanded side bolsters and integrated head restraints. Red stitched "Si" logos in the seatbacks also set them apart.

New seat frame designs are 17-percent lighter compared to the previous generation Si, and are more comfortable and more adjustable. A relocated seatback recline pivot point improves comfort, and the range of the seat bottom height adjustment has been increased by 10mm (0.4 in). To help improve the forward view and create a feeling of openness for rear seat passengers, the front seatbacks have a narrower upper profile and smaller integrated headrests. The Civic Si seats feature fabric seating surfaces for breathability and comfort.

The driver's seat is manually adjustable for fore-and-aft, seatback angle and height adjustment. Additionally, heated front seats are available for the first time on the Civic Si. The 3-level front seat heater controls are positioned within easy reach, just below the climate control system controls.

For easy access to the second row of seating, The Civic Si Coupe passenger-side seat has a convenient one-touch walk-in feature.

Split-Folding Rear Seats The Civic Si's roomy second-row seating is designed for maximum comfort and versatility, with a folding seatback. In both Coupe and Sedan Si models, a 60/40 split and folding design makes it easy to accommodate passengers or long cargo.

Center Console The Civic Si interior offers a range of convenient storage features for the driver and passengers. The center console is specially engineered to offer a sporty appearance coupled with versatile usability. With the prevalence of smartphones in most people's lives, the console is engineered around a "tech center" theme. Up front, it has a 2-tier smartphone tray with a wire management pass-through for organized connectivity. A rubber mat helps secure a phone and LED lighting is included for nighttime visibility. There's also an additional phone storage pocket on the driver's side.

An electronic parking brake replaces a conventional manual parking brake lever, freeing up more console space for a larger armrest and greater storage space. The main storage compartment is topped by a sliding, deeply padded armrest. A pair of cup holders are centrally located, and can accommodate large 42-ounce cups when the padded armrest is placed in the rearmost position. By sliding the adjustable cup holder rearward, there's space to accommodate even a large sports drink bottle. Inside the console, a small item tray slides fore and aft the full length of the console. With the cup holder removed, the console offers a class leading 7.2-liters of storage, enough to accommodate iPads and other large items.

Trunk The Civic Si Coupe has a trunk capacity of 11.9 cubic feet and the Civic Si Sedan has a trunk capacity of 14.7 cubic feet – both among the largest in the competitive class. Spacious enough to easily accommodate four large golf bags, the trunk areas in both the Si Coupe and Si Sedan are easy to access and use. Inside, the cargo floor is longer front to rear, and the vertical height of the cargo compartment has increased when compared to the previous generation Si models. A 60/40 split and folding rear seatback makes it easy to expand the cargo area. The trunk is carpeted and lined, and a temporary spare is located in a well under a removable section of the cargo-area floor.

Steering Wheel The leather-wrapped Si steering wheel incorporates the most commonly used controls, allowing the driver to keep their hands on the wheel and their attention on the road. Bluetooth® HandsFreeLink® and audio system controls are located on the left side of the steering wheel, and include a touchpad control that makes is easy to scroll and select items that appear on the audio screen. Cruise control controls are on the right and Driver Information Interface (DII) controls are located on the left side. The steering wheel offers manual tilt and telescopic adjustment.

Shift Lever Historically, all Civic Si models have had manual transmissions, to give the driver maximum control for performance driving. In the 2017 Civic Si the shift knob is crafted from aluminum alloy and leather, for a performance look and feel. The drive mode selector button nearby lets the driver choose between NORMAL and SPORT driving modes.

Power Windows, Lock and Mirrors

Power windows are standard equipment on all Si models and include auto-up and -down operation on the driver's and front passenger's windows. Power door locks and power mirrors are also standard equipment on all Si models and include heated exterior mirrors. Smart entry is also standard.

One-Touch Power Moonroof with TiltFeature All Civic Si models have a standard one-touch power moonroof with tilt feature that will fully open or close with a single touch of the switch. (See the Exterior section for more information.)

Climate Control Systems All Civic Si models have a standard automatic climate control system now featuring a refrigerant with a much lower GWP (Global Warming Potential). To help conserve energy, the system employs a Variable Displacement Compressor (VDC). Unlike a conventional compressor which can only operate at 100-percent and must be switched on and off frequently to conserve fuel when the cooling load is relatively low, the VDC can vary its output based on the cooling needs, resulting in greater efficiency, reduced drag on the engine and smoother climate-control performance.

For the optimal comfort of both the driver and front-seat passenger the system features dual-zone operation. In addition to physical controls, the Display Audio touchscreen also incorporates climate control functions.

Sliding Sunvisors To provide more flexible shading from the sun, all Civics Si models come standard with sliding sunvisors. The driver and front passenger sunvisors can now be moved along their mounting shafts, with 3.9 inch range of motion, to provide perpendicular shade for the eyes even when the front seats are in their rear-most position.

Meters All Si models have a unique red-themed central Thin-Film Transistor (TFT) Driver Information Interface (DII) color display that depicts an analog tachometer, digital speedometer and additional selectable information. The instrumentation offers two distinct looks, depending on which drive mode has been selected using the console-mounted switch, NORMAL or SPORT.

In SPORT mode, the Ambient Meter (located above the Driver Information Interface) illuminates Red and flashes as the engine nears the rev-limit.

Driver Information Interface (DII) The Civic Si instrument panel provides important vehicle information via a Driver Information Interface (DII) positioned centrally in the meter panel. Controls positioned on the left side of the steering wheel allow the driver to cycle the DII display through multiple screens of information.

On the 2017 Civic Si, the Driver Information Interface includes a range of selectable real-time information designed to support performance driving. The 7-inch TFT screen can display throttle input and brake input application in a graphic percentage format, turbocharger boost in pounds per square inch (psi), a race-inspired Rev-limit indicator, a graphical G-Force gauge providing a representation of acceleration, braking and cornering forces, and a lap timer (intended for use on closed circuits). The lap timer is activated using the directional pad on the left side of the steering wheel.
