Honda totally revamped the Civic lineup in its entirety for the latest model year, with the updates extending to the sporty Civic Si Sedan. Changes to this driver-focused four-door include a subtly updated look inside and out as well as a enlarged engine that provides more torque but doesn't rev as high as its predecessor.
The Civic Si Sedan is the slightly more practical option of the sporty Si twins thanks to its extra set of doors, but it still packs the same potent punch as its slightly shorter Coupe lineup mate. Despite the "grocery getter" four-door layout on the Si Sedan, Honda remains true to the sporty heritage of the Si line, only offering the model with a manual transmission.
While Honda calls its entire Civic lineup "all-new," only the Civic Si and Hybrid models were lucky enough to be gifted entirely new engines. For the Si, Honda's sportiest Civic, the difference was .4-liters of added displacement that added just four horsepower, but more importantly, 31 lb-ft of torque.
While the peak numbers being larger are of course a welcome change, the real key change is that the power comes at lower engine speeds. The outgoing model required 7,800 rpms to hit its peak horsepower and 6,100 rpm for peak torque, now the Civic Si engine requires just 7,000 rpm for peak hp and 4,400 rpm for max torque. This change in the usable power band equates to a much more street-friendly driving experience, although some Si fans will miss thrill of running the outgoing motor to its stratospheric redline.
This upgraded engine - a transplant from the Acura TSX - is mated exclusively to a six-speed manual transmission and benefits from a helical-type limited-slip differential (LSD) to get power to the ground. Fuel economy is rated at 22 mpg in the city and 31 mpg on the highway.
Unique styling abounds on the Civic Si Sedan to convey its sporty nature, ranging from more menacing front and rear fascias, side skirts, a body-color deck lid spoiler with an LED center brake light, fog lights and a chrome exhaust finisher. Wheels come at a sporty 17-inches with 215/45R17 tires.
Inside, Honda continued its heavy dose of sport with bolstered perforated cloth sport seats with suede-like trim and red stitching as the main attraction, accented by a matching leather-trimmed and red stitched steering wheel and gearshift knob. The unique touches are extended to several pieces of aluminum accents, including the shift knob base and pedals.
The latest Civic Si Sedan also features a new "intelligent" Multi-Information Display (i-MID) that includes an exclusive Power Monitor (as one of its screens) that can indicate the percentage of total horsepower generated by the engine. Honda also added a Sequential Rev-limit Indicator in the upper instrument panel to show when the i-VTEC high-lift camshaft profile is engaged, as well as to show incrementally when the engine redline is approached and reached.
The Honda Civic Si Sedan's safety features include two-row side curtain airbags, dual-stage, multiple-threshold driver's and front passenger's airbags, driver's and front passenger's side airbags, Vehicle Stability Assist (VSA), anti-lock braking (ABS) with Brake Assist and a new Motion Adaptive Electric Power Steering system that helps the driver steer in the ideal direction to mitigate oversteer or understeer situations.
Key Competitors
Competition to the Civic Si Sedan comes from turbocharged compacts like Volkswagen Jetta GLI, the Subaru Impreza WRX and the somewhat awkwardly named Mazda Mazdaspeed3.
