Whoopsy:

In reality the G500 is not that much better in fuel economy than the G63. You might last a couple hrs more, that's about it laugh

I think the same. That beast took 27 liter/100km and we really been driving decent. Question is anyway why not taking a G63.

@Bjoern - believe it or not, but I read on some Forums that the Diesel is also taking up to 20 liter. So there is not really a huge difference and you still lack the sound and the power.
