 I have been generally amazed at how much I like my Golf TDI. I came from an Audi S4 so less power is very obvious but the diesel torque curve is so good this car is really enjoyable up in the Rockies. MPG is about 36-38 in winter and 38-40 in summer. Longer trips will average 41-44 but I have seen 52 mpg on a 120 mile freeway trip and 5-8 mpg on a really cold morning commute:} I think the Fuel Injection and Engine Management electronics are very rudimentary and you can feel it compensating all the time for hills and other situations. Turbo lag is nothing like as bad as in a Mini but is still very noticeable. Putting it in Sport certainly helps but then mpg plummets.
