I've begun following the news in Europe surrounding the recent of approval passed down by German courts to ban diesel in German cities. Apparently Rome is following suit, and there are rumblings in the UK news of potential bans and/or additional taxation on diesels. In heavier news, some outlets are claiming that diesel is dead (Diesel is DEAD: World’s biggest car maker says it is SCRAPPING diesel cars FOREVER) in the wake of Toyota's announcement that they will no longer sell diesel vehicles in Europe. Needless to say, a cursory Google search will reveal that diesel is getting a lot of bad press in Europe at the moment. Meanwhile in the USA, Popular Mechanics is over there writing about the US diesel revival (The Fledgling Revival of American Diesel). Ford, GM Nissan all continue to offer diesels in their trucks, with a handful of European auto makers still bringing diesel offers to the states. It would seem the the US and European market are presently trending in opposite directions on diesel. Of course these seem like pretty different markets from one another, but still interesting. I collect all this information above to contextualize the following question: In light of recent developments in Europe, what, in your opinion, is the future of diesel in the USA? Will the USA follow suit in terms of regulation and possible banning of diesel vehicles, or will diesels continue to roam free within our borders for the foreseeable future? Do you believe diesel vehicles will continue to be operable under the 25 year rule and antiquing, or will older vehicles soon be banished from the roads? I know no one can predict the future, but I'm very interested to hear the opinions of the MUD community on this matter, particularly those of you that drive these rigs everyday and are also likely more keyed-in to the US automobile sector as a whole than myself. What are your thoughts on the viability of diesel vehicle ownership in the USA over the next 10-20 years?
