Civic Hybrid Unique Body Features
The Civic Hybrid incorporates unique body features, they are:

Civic Sedan, Coupe and Si Fuel Tank
The Civic is equipped with a six-layer resin fuel tank that offers reduced weight, increased capacity, and reduced emissions. Capacity is maximized to 13.4 gallons because the resin tank can be molded to fit around various components. For 2006, the shape of the fuel tank was optimized to reduce fuel evaporation. This reduction lowered evaporative emissions by 75 percent, helping the Civic to achieve a LEV-2 rating. The Civic also incorporates a returnless fuel supply system that helps reduce vapor generation.

Civic Hybrid: Composite Zero Evaporative Emissions Fuel Tank
A critical component to complying with Advanced Technology Partial Zero Emission Vehicle (AT-PZEV) regulations involves having a zero evaporative emissions fuel tank. Traditionally, those tanks have used steel construction instead of composite construction because some extremely small amounts of fuel vapor (hydro carbon permeation) can escape from the polyethylene resin composite construction. Honda has pioneered a new six-layer polyethylene composite design that provides zero evaporative emissions performance while also decreasing weight and increasing fuel capacity. Compared to the previous PZEV steel gasoline tank, the new composite gas tank weighs approximately 8 pounds less and holds about a half-gallon more fuel (12.3 gallons total).

Available Colors
The Civic is available in thirteen exterior colors and four interior colors. Some of the colors are exclusive to a particular model such as the Si or Hybrid, and the interior colors are typically exclusive to a particular color and/or trim level.
