Are foreign automakers more environmentally-conscious about fuel efficiency than their American counterparts?  Well many believe so, but if  recent trends are any indication, it appears it may be Japanese, not American, gas guzzlers that are making more traction with the general public.  This, according to the New York Times, which notes that while Japanese automakers are gaining much publicity about their hybrid vehicles, like the 55 mile per gallon prius, in actuality it’s the sales of new Japanese SUV’s and light trucks that are growing the fastest.  Indeed, Toyota’s carbon emissions increased the most, by 72 percent, compared with 33 percent for the entire market. Facts like these may force the Green image of Japanese cars to commit hari-kari.
