I'm sure they mean gasoline-based (aka petrol), not diesel. Here in the US we have almost no diesel options at all. VW and Audi have TDIs but they're very few and hard to find. Even the Chrysler 300 turbo diesel was never sold here.

This is a serious issue for modern diesels, whereas diesels of old could handle any hydrocarbon approximation without much fuss.The other major factor is that the quality of diesel throughout your country is very different.

That's because of your crazy regulations regarding diesel imports and exhaust limits (or shall we say protectionism?). The other major factor is that the quality of diesel throughout your country is very different (most of it being worse than McDonalds frying oil after three days in the pot), so you can't have a proper reference or ensure any consistancy as far as "guaranteed" exhaust limits go.
Modern diesels have way lower consumption than gasoline cars, but will never drive nearly as responsive. So there is still no be-all-end-all solution.
EDIT: as for that consumption figure, while it does sound impressive at first, it's not the real-life consumption. All of us lie there, the tests are rigidly defined and there's lots of cheating going on everywhere. Modern engine ECU will even recognize the test pattern and adjust accordingly.
Doesn't most of the passing happens in pit stops.Totally just saying, but diesels have won the Le Mans 24hr for the last few years.
Are you sure thats not because you've been driving turbo diesels?I'm not so sure how well a diesel engine would work for an American sports car. I've driven a few normal diesel cars and you always have to rev their nuts off in the lower gears.
Well the last one was a turbodiesel Jaguar station wagon. My point is that driving them is pretty different and probably just isn't a realistic engine change for an established American car like the Mustang.Are you sure thats not because you've been driving turbo diesels?
One of these days, you'll turn over the page of the calendar, and you won't need to be reminded that it's not 1991 anymore. Well, I suppose if you'd like to fantasize that you're still a teenager, then wanting to continue living in that time period might explain your need to delude yourself that you're still in the era when exotic sports cars could be had for under the price of an average home, and diesels still spewed clouds of noxious black smoke. You might as well continue to indulge in that delusion... but be careful where you tread. Espousing a personal delusion as a truth claim is the realm of religion, not automotive engineering.In fairness though Mize we have solid reasoning behind our lack of diesel cars, diesel cars do suck and all.![]()
Not in the U.S. The US doesn't measure emissions based on mileage the way other countries do. They really only measure air quality per unit volume of exhaust, not total quantity of exhaust gas components per unit of distance traveled. Yes, I suppose if the EPA actually understood that people drive distances rather than cubic meters of exhaust, they might put two and two together, but the domestic manufacturers are probably also happy to be able to keep certain competition out of the picture, and since gov't agencies are invariably ruled by the highest bidder, I think that pretty much defeats that idea.Diesel has lower emissions if you use the same rules as for gasoline cars.
That part, I think is slowly being rectified in some states, but it is true that it's not yet implemented nationwide. Then again, there are some grades of regular petrol that aren't even available in all 50 states just because they don't want to encourage people to purchase cars that demand such fuels.The other major factor is that the quality of diesel throughout your country is very different (most of it being worse than McDonalds frying oil after three days in the pot), so you can't have a proper reference or ensure any consistancy as far as "guaranteed" exhaust limits go.
Well, even without that, it would certainly explain why a 300 hp+ vehicle, petrol or diesel would score better than 30 mpg since much of what constitutes the testing schedule falls in the range of daily driving, where you're really not pushing into massive engine load. Diesel especially, would probably benefit here since it has the capacity to limit fuel flow rates to points far leaner than gasoline spark ignition. Closest that gasoline engines can do is cylinder deactivation under low load, which is quite feasible to produce good results in the highway driving schedule (also a good reason why the Mustang sees such a large gap between its city and highway rating).EDIT: as for that consumption figure, while it does sound impressive at first, it's not the real-life consumption.

Responsive on what scale?_xxx_ said:New turbos are either two-stage turbo (a little fast rotor for lower engine rpm and a big one for high rpm), or adjustable blades, so that is not a problem any more. But still it's way less responsive than a gasoline engine.

Have you guys tested biodiesels? These seem promising, at least from a health perspectve because they have no aromatics so they are less carcinogenic than petroleum diesels.
I don't know what the obsession with diesel is about. When we refine oil, we get diesel and gas in a fixed ratio. Right now we have a good balance between the two types of vehicles, making the price roughly similar.
If there were many more diesel vehicles, demand for diesel would go up, price would go up while gasoline cost would go down, and you'll have pressure to restore the balance back to the way it is now. It would be pointless for car manufacturers to make push for diesel cars in North America.
