Please don't take this that I'm trying to rubbish your idea Phil - I'm not; I'm just interested in your opinion because it's a different angle on this long-standing diesel v petrol debate that I'd not really thought about before.
what you've said is not untrue

the essence of what I was saying is that for an identical driving speed, in an identical gear at full throttle the petrol turbo car in this example would give you more acceleration than the diesel
