I got beat up when I proposed that the GX Civic was a cleaner car... but somebody posted a link to a gov site indicating that the hybrid was better (in that in produced less emmissions) what wasn't clear is what kind of emmissions. I still haven't heard anybody tell me which is truly cleaner. A GX (natural gas) civic or the HCH? The GX articles that I find flaunt the fact of how clean the car emmissions are (more so than any other fueled car out there).
