They also got/get taxed on the displacement of their engines....more CC = $$

Main trend here now in diesel powered cars is 1.4 - 1.5 liter (85-91 cu in) 70-90hp for small city cars, 1.6 liter (98 cu in) up to 110 hp, and 2 - 2.2 liter (122 - 134 cu in) over 110 hp, with consumption 4-7 liter of diesel/100 km (60-33 mpg).
And of course, manual shift in 95% in that car class (5 or 6 speed) /forums/images/graemlins/grin.gif
I'm driving 2.0 liter 90hp common rail diesel, about 4mpg, ususal at 1750-2500rpm.

This reminds me of the conversation I had with a gentleman when I was in England several years ago. I noticed that engine dispalcement of most cars was 2 liter or less. I told him that the pick-up truck I drove had a 5.7 liter engine, he almost dropped his teeth exclaiming why do you need such a large engine.
I thought about it for a minute and didn't really know wht to say except that I tend to put alot of weight in the truck and pull heavy things with it. We also like to reach 60 MPH in less than 10 seconds.
Today I am happy driving a car with a 1.7 liter engine manual shift and getting 44 miles per gallon. As for lugging a diesel which was the main topic is black smoke always an indication of lugging? I aways thought that lugging and low RPM went together.
There are times when going along the road and heading up hill at 1800 RPM when I see a trace of black smoke coming from the exhaust. I think more fuel is going in than can be burned for just 10 to 15 seconds, but does this hurt in the long run?
What about low RPM and heavy work and no black smoke is this still lugging?

Black smoke or even white smoke (raw unburned fuel) is evidence of overfueling which is what occurs when you lug the engine.
It is not a problem for momentary operation, but if you are going up a long steep grade with a heavy load at elevated altitudes it sure is a major problem due to the extremely high EGT generated and the hot spots in the combustion chamber where raw fuel is touching cylinder walls and piston crowns. If you have a turbocharger, the turbine housing will be way hot and the tips of the turbine will be melting away.....
Low RPM heavy load and no black smoke is not lugging.
