The Civic Si Coupe and Sedan models prioritize handling and performance with a sport-tuned suspension and a 2.4-liter i-VTEC 4-cylinder engine. More powerful than the 2.0-liter engine in the previous generation, the new engine produces 201 horsepower @ 7000 rpm and 170 lb-ft. torque @ 4400 rpm, an improvement of 4 peak horsepower and 31 lb-ft. of peak torque compared to the previous model. A sport-minded 6-speed manual transmission with a helical-type limited-slip differential (LSD) is standard. The LSD helps the Civic Si accelerate powerfully when exiting corners as both wheels can deliver more equal torque distribution to the road compared to a conventional open differential. The tall sixth-gear ratio allows for relaxed highway cruising. Unique Civic Si exterior features include fog lights, 17-inch alloy wheels with 215/45R17 tires (summer tires available), a body-color deck lid spoiler with an LED center brake light, and a chrome exhaust finisher. Inside is an exclusive aluminum shift knob with leather, textured aluminum pedals, and firmly bolstered perforated cloth sport seats with suede-like trim and red stitching. The steering wheel is leather-trimmed with red stitching. The i-MID on the Civic Si includes a new Sequential Rev-limit Indicator and Power Monitor.
