Orange guy, it may "appear" to be an EPA issue but in reality its a $$$$ market share issue. The biggies like GM and Ford whom I worked for(can't speak for chyrsler/Daimler etc) played the legal fight game after the Toyota and Honda groups as a last ditch effort. Instead of really trying to compete they just went the "political" route. GM lost such a percentage that they will never recover. The writing was on the wall but they did not want to read it. Hasn't changed never will. NH is no different in my humble opine, they can try to slow it in the courts but the inevitable end can be seen, just a bunch of legal BS, but the laywers make out. Look what happened when Kubota came out,,,,,,,,you know, superior product with lower price tag. They are now about the "prize" of the market. I'm not saying the china stuff is anyway near the Kubota quality just the $ tag is lower and that means lost possible sales which equals market share.
Instead of having a humongous legal department to handle issues/lawsuits like "color" infringements maybe the BIG and I mean all Big corps should think about quality as well as the price tag and not the net profit per quarter.
Just my opine.
