Commenters on this article are acting like loosening emissions and fuel-economy targets for cars sold in America will bring back dirty big-blocks that spew unburned hydrocarbons. They’re morons.
We already have 6-7L V8's that make twice the power as their 1960's predecessors and do it while achieving amazing mileage and burning cleanly. It’s actually amazing how good new engines are. Relaxing the environmental standards won’t make a new wave of performance cars or anything. It just means that every single shitty compact car driven by someone who just wants to get home will now pollute multiple times more than cars currently do.
I own a 1970 Corvette. I know pre-smog cars rule and I’m hardly an environmentalist. But when I hear about deregulating CAFE standards I just get nauseous. We have cities like LA with brown air and we’re going to tread backwards? My head.
