For the 2015 Civic Si, Honda engineers worked diligently to optimize the engine's output, ensuring it provides an exhilarating experience for the driver. Moreover, the engine's design incorporates Honda's renowned i-VTEC technology, which enhances both power delivery and fuel efficiency.

This means you get strong low-end torque for everyday driving and a surge of power when you rev the engine higher. This balance makes the 2015 Civic Si a versatile car that's equally at home on city streets and winding roads.

Horsepower and Engine Details

So, what's the magic number? The 2015 Honda Civic Si boasts 205 horsepower at 7,000 rpm.

Along with the 205 horsepower, the 2.4-liter engine also produces 174 lb-ft of torque at 4,400 rpm. Torque is what gives the car its pulling power, especially from a standstill or when accelerating in gear. The combination of high horsepower and ample torque results in a car that feels responsive and eager to perform. The engine's redline is set at around 7,200 rpm, encouraging drivers to explore the upper reaches of the rev range. This is where the i-VTEC system truly shines, providing a noticeable boost in power as the engine approaches its peak output. To further enhance the driving experience, the 2015 Civic Si is exclusively available with a 6-speed manual transmission. This not only gives the driver full control over gear selection but also adds to the car's sporty character.
