I think i really comes down to driving styles. The tdi prob feels faster because the boast comes on really quick and is a breeze for overtaking so your more likly to use its performance The petrol will suit the driver who likes to plan ahead and loves to rev to the red line
Oh the Tdi sounds like a tractor on tickover
I like tractors, driving a diesel is a different experience, which I've come to like. It doesn't seem to matter how loaded up you are with passengers and luggage, the diesel car doesn't suffer in the performance and economy stakes. Even with 6gears you will have trouble finding the correct gear to get the max performance. The wife always comments that it doesn't matter which gear you are in it always pulls away sufficiently for her driving style, having been a passenger with her she doesn't ever know which gear she is in
" there too many gears in this car" she usually says.
