Powering the Honda Civic Si is a high-performance, high-torque 1.5-liter, directed-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 thrilling new driving experience with more low-end grunt and increased torque output across the engine's full rev range compared to the previous Si. Peak output of 205 horsepower1 arrives 1300 rpm lower in the rev range, and the greatly increased peak torque of 192 lb-ft2 (+18 lb-ft) is produced 2300 rpm earlier and sustained over 70 percent of the rev range. Allowing full utilization of the powertrain, the 2017 Civic Si's rigid body includes highly upgraded chassis and drive components, including a dual-pinion adaptive electric power steering system with variable ratios, sport-tuned suspension, an adaptive damper system, a helical limited-slip differential, larger front brake rotors (12.3-inch) and wider 235/40 R18 tires. In addition to adaptive dampers, suspension upgrades over the Civic EX-T include stiffer spring rates, more rigid stabilizer bars (+7 percent front, +26 percent rear), and solid front and rear compliance bushings, the latter shared with the track-focused Civic Type R. The 2017 Civic Si now features two driving mode options - Normal and Sport - allowing the driver to choose vehicle dynamic characteristics according to their tastes and the driving environment. From the more comfort-oriented yet well controlled default Normal Mode, the Sport Mode adjusts the suspension damping characteristics plus steering and throttle response for a more taut and direct driving experience.
Interior Comfort, Convenience and Connectivity The new Civic Si variants offer premium comfort and convenience features building off the EX-T Civic Sedan and EX-T Civic Coupe, including a 7-inch Display Audio touchscreen that serves as the nerve center for control of audio, HVAC and other functions. The Display Audio is integrated with Apple CarPlay™ and Android Auto™ platforms, providing seamless integration of smartphone features and functions, including app-based navigation, streaming audio, voice-controlled search capabilities, and access to a host of Apple- or Google-approved smartphone apps. All Si models feature a 450-watt, 10-speaker premium sound system with AM/FM, SiriusXM® Radio, HD Radio™ and Pandora® capability. 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 input and brake input application in a graphic percentage format, turbocharger boost in pounds per square inch (psi), lap time (intended for use on closed circuits), race-inspired Rev-limit indicators, and a graphical G-Force gauge that provides a representation of acceleration, braking and cornering forces In addition, the 2017 Honda Civic Si Coupe and Sedan gain several premium features for the first time ever on a Si model including heated front seats (both cushion and seat back), dual-zone automatic climate control, Walk Away Auto Lock® and an electric parking brake with hill start assist.
Interior 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. 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.
Powertrain For the first time in Civic Si history, an advanced turbocharged engine powers the Honda Civic Si Coupe and Si Sedan. An enhanced version of the 1.5-liter 16-valve DOHC direct-injected turbocharged powerplant that powers EX-T, EX-L and Touring Civics, the new Si engine pushes performance on multiple fronts. It's rated at 205 hp at 5700 rpm and offers an impressive 192 lb-ft. of torque between 2100 and 5000 rpm. That's an increase of 31 hp and 25 lb.-ft. of torque, as compared to other 1.5-liter turbocharged Civic models.
