I have a feeling most carmakers have been fiddling with the emission software in order in pass smog. I feel it's just a matter of time and testing, and I don't think it will just be diesels. I looked into Ford's GT-350 and it's, I believe, the fasted stock vechicle Ford has ever produced. It passes smog with flying colors. Engineers claim is just good engineering. I hope that's the case. I am for reasonable smog requirements. I know how hard I have to tune, and repair my 4 banger in order for it to pass every two years. My biggest fear is the federal will tighten smog requirements to the point where most older vechicles won't pass. I am poor. I drive a 4 cylinder vechicle. My vechicles are always in tune. I consider myself a enviormentalist. I still hope I can afford to drive in the future? I know I will probally never be able to buy a new vechicle.
