The 2018 Honda Civic Si Coupe and Sedan has rolled out to dealerships in the U.S.A. At a starting price of USD $23,900 for either the Si Coupe or Si Sedan, the exciting and dynamic Civic Si duo, revealed just last month, are the latest and sportiest additions to the 10th-generation Civic lineup.

At a glance, the Civic Si features an aggressive front fascia with gloss black Honda “wing” and large lower air intakes, along with 18-inch split 5-spoke alloy wheels featuring a model-exclusive machined finish, low-profile tires and a chrome center-mounted polygonal exhaust finisher. From the rear, the Si Coupe continues the Civic Coupe’s distinctive full-width light bar and adds a prominent raised wing spoiler, while the Si Sedan includes an exclusive rear fascia and decklid wing spoiler incorporating a LED brake light.

Inside, the Civic Si features exclusive bolstered front sport seats with red stitching, including stitched Si logos, which carries through to the doors, leather wrapped steering wheel, shift boot and sporty leather and aluminum shift knob. The red color scheme carries through to the driver’s TFT meter as well as audio system illumination. Finally, aluminum sport pedals and carbon-look instrument panel trim finish off the Civic Si’s unique interior appearance.

New for the 2017 Civic Si is a Driver Information Interface (DII) that adds a range of selectable real-time information designed to support performance driving. The 7-inch color TFT can display throttle and brake application in a graphic percentage format, turbocharger boost in pounds per square inch (psi), lap time (intended for use on closed circuits), race inspired shift lights and a graphical G-meter that provides a representation of acceleration, braking and cornering forces.

Accommodating modern connectivity needs, the new Civic Si includes a 7-inch Display Audio touchscreen that serves as the nerve center for control of audio, HVAC and other functions. The Display Audio features CarPlay and Android Auto platforms, providing seamless integration of smartphone features and functions. All Si models take up a 450-watt, 10-speaker premium sound system with AM/FM, SiriusXM Radio, HD Radio and Pandora capability.

Powering the Civic Si is a high-performance, high-torque 1.5-liter, direct-injected and turbocharged DOHC in-line 4-cylinder engine with dual variable cam timing (dual VTC). Mated to a short-throw, 6-speed manual transmission, the powertrain provides a dynamic driving experience with a much broader power band and significantly increased torque output compared to the previous Si. Peak output of 205 horsepower2 arrives 1,300 rpm lower in the rev range (5,700 vs. 7,000 rpm) and peak torque of 260 Nm (192 lb-ft) is produced 2,300 rpm earlier (2,100 vs. 4,400 rpm) and sustained over 70 percent of the engine’s rev range.

Both Si Coupe and Sedan feature a more rigid body and upgraded chassis components, including a dual-pinion adaptive electric power steering system with variable ratios, sport-tuned suspension featuring a two-mode adaptive damper system, a helical limited-slip differential, larger 12.3-inch front brake rotors (+0.5 inches) and wider 235/40 R18 tyres. In addition to adaptive dampers, suspension upgrades include stiffer spring rates, more rigid stabilizer bars (+30 percent front, +60 percent rear), solid front and rear compliance bushings, and ultra-rigid front upper control arms shared with the track-ready Civic Type R. Wheel track for the new Si Sedan and Coupe has increased 1.2 inches at the front and 0.3 inches at the rear, offering improved stability, a lower center of gravity and improved cornering performance. The Civic Si Coupe and Sedan offer two dynamic driving modes: Normal and Sport.

The 2017 Civic Si Coupe and Sedan are designed to provide a high level of collision safety performance in a wide variety of collision scenarios, including offset and oblique-angle frontal collisions as well as side and rear impacts. The Civic’s safety performance starts with its class-leading forward visibility and precise, stable and predictable steering, handling and braking performance. Standard four-channel anti-lock brakes (ABS) with Electronic Brake Distribution (EBD), Vehicle Stability Assist (VSA) with traction control and Agile Handling Assist further enhance dynamic stability and emergency maneuvering and braking performance.
