Somebody made a comment a while ago about the F10 520d being underpowered, and it got me thinking.

The 520d is now the most common BMW on the roads and a very popular car. The F10 is more comfortable than the e60 but its also a lot heavier. Has the new 520 become underpowered.

I have test driven them, and I have to say mated to the auto gearbox, its a bit of a slug. The 20d engine in a e92 is well powered but in the F10 I think its just not enough. Also the claimed fuel consumption is just a fantasy.

What are other peoples thoughts, and I realise that underpowered is a subjective thing.
