Honda Civic Si Research

The Civic Si is the flagship example of Honda's si technology in an efficient practical package. It is based off the regular gas-powered Civic that has been a best seller in the compact car market for years.

The Civic Si is only available in a sedan model. It is powered by a 1.3-liter four-cylinder gas engine and a light-weight, brushless electric motor that is sandwiched between the engine and the CVT transmission. Combined, the gas engine and electric motor produce 110 horsepower and close to 45 mpg on the highway. Standard safety features include anti-lock brakes, six airbags, tire pressure monitoring system and active front head restraints.
