Well, first of all, if you've privately engineered your 1999 Taurus to get 51 MPG, that's not quite the same thing as saying that you have a 1999 Taurus which gets 51 MPG. If you've really been able to squeeze out 25 extra MPG out of your car, I'm very proud of you, but I have to wonder why you didn't mention this from the beginning.
At any rate, private citizens have been able to reach MPG levels over 200 by converting ordinary cars:

About your other questions: I didn't realize this was Quiz Show. Cars pollute less now than in the 1970's for one obvious reason: they're required to pollute less now than in the 1970's. Why does diesel cost as much as or more than gasoline? Because of the Marshallian Cross. Really, what are you getting at? If you have some larger point to make, I'd prefer to hear it--rather than playing guessing games.

The problem with todays cars and gas mileage is the engine is built wrong for gas mileage.Todays engines are high rpm horsepower engines.For good gas mileage we need low rpm torque engines.They put in overdrive transmissions that lower the rpms at highway speeds.When they do this it puts the engine in the torque rpm range.But they are a low torque engine.Torque is what accelerates the car and horsepower is what maintains speed.Torque is produced at low rpm and horsepower at high rpm.The closer you can get the horsepower and torque range together the better gas mileage you will get.And a low rpm torque engine will get better mileage in the city than a rpm horsepower engine.
I could make a big old Cadilac engine from the 70s get 30mpg.It is not hard to do.They got about 16-20 mpg back then in a big car.
I am asking you a serious question now.
Do you know why a 2005 car or truck pollutes less than say something from the 1970s?
I will not give you a hard time about this.But you are an enviromentalist so I am asking you.Again I will not give you a hard time.
Do you know why Diesel fuel costs as much or more than gasoline?
Anyone can answer.But it is directed to Lordandmaster.
I didn't change anything on my car.
I didn't want it to be a quiz show.I thought you would know the answers.
Yes,you are correct.Even more so than you think. Todays engines pollute slightly less than older engines because of computerized fuel injection.Over all they still pollute almost as much as the older engines.But the reason why they pass the emissions test is the catolitic converter and the fresh air that is either pumped,or sucked into the catolitic converter.They dilute the exhaust with fresh air and measure the results coming out the tailpipe in parts per million.And the reason for this is as you said they are required to pollute less. If an older car gets 20 mpg and a newer car gets 20 mpg they use the same amount of gas and pollute pretty much the same.They can reburn the exhaust to burn the fuel that didn't burn but the engine still pollutes the same.
The reason why Diesel costs as much or more than gasoline is greed. In the process of refining crude into gasoline the first refind fuel is Kerosene.Then I can't remember the exact order because I am always going on memory. Not something I read yesterday but years ago. Kerosene,Jet fuel,home heating oil,Diesel fuel,gasoline,white gas like is used in Colemen stoves and lanterns.So it costs less to produce Diesel fuel and the reason why they don't sell it for less money is people would run more Diesel cars and pickups and less need for Gasoline cars and pickups.Plus they add a lot of additives to gasoline to make it pollute less.So that drives up the cost of Gasoline.And as long as Gasoline is inflated then they can inflate Diesel fuel.All for greed and the lack of people pushing for the truth and lower cost fuel.Instead people push for fuel alternatives.And that allowes for them to keep the prices up.
I wanted to add that when I said poor driving habits I didn't mean poor driving.
