But here is what we should take a look at. For this example let's look at the BMW 3 series coupes, one with diesel the other with gasoline engine. Both have inline 6 cylinder engines with twin turbos. The diesel one is 2993cc and the gasoline twin turbo displaces 2979cc. http://www.bmw.co.uk/bmwuk/pricesand...-bmwuk,00.html

The diesel makes 286 horsepower @ 4400 RPM and 580 NM torque @ 1750 RPM. 0-62 acceleration is in 6.1 seconds, combined fuel economy of 37.7 (British) mpg.

The gasoline engine makes 306 horsepower @ 5800 RPM and 400 NM of torque @ 1300 RPM. 0-62 acceleration in 5.7 seconds (with automatic like the diesel engine) Combined fuel economy of 29.7 (British) mpg.

The diesel 3 series coupe is 30 kg heavier and probably runs more boost.
I'm honestly not quite sure what you are trying to say here, or what this proves. But maybe it's just me and I've missed your point (so forgive me if that's the case).

Let me just add to the figures you have presented:

BMW 330 petrol 50-75 mph in 4th gear 6.5 seconds
BMW 330 diesel 50-75 mph in 4th gear 4.9 seconds
