Did you see what happened to the vw golf diesel?
The engineers fudged how the fuel savings were obtained but it was much better than other vehicles on road. I was getting abou 48 to 52 mpg. Very nice.
The government had a target. The leftists in the agencies were delighted to wield their bureaucratic power.
There is the real problem.
We have an EcoDiesel Jeep, get’s 27.5mpg every week in mixed driving. Exploring the Florida Keys it got 35.5mpg. Our EcoDiesel Ram truck gets the same mileage. I am all for diesel tech being pushed but the libs in government have been killing diesels by demanding electrics.
