And that is, indeed, the truth. Broad, flat torque curves with lots of "area under" not only improve driveability, but improve fuel mileage, due to the reduction in time spent with large amounts of throttle input.

Hence, this is probably why the traditional "diesel versus petrol versus turbocharged petrol" seems to favor diesel until technology catches up on the turbocharged petrol side of the house.

Interesting. Thanks for bringing a engineer's perspective into the discussion. I know a fair amount about things like this, but it was good to hear another side of the story, rather than gas purists screaming at diesel enthusiasts, and vice versa.
