The Good Old Days
Several years back, the 1975 Honda Civic CVCC became the first vehicle to pass the emissions requirements of the Clean Air Act without using a catalytic converter.
The Good New Days
The 2010 Civic features technological achievements that are every bit as impressive as its predecessor’s. Today's Civic Coupe sports a 1.8-liter engine that provides exceptional fuel economy (25 mpg city/36 mpg highway)[1], and qualifies as an Ultra-Low-Emission Vehicle (ULEV-2)[2].
