Between the no hatchback and dpf issues I'm unlikely to be replacing my 6 with another. The new skyactiv-d engine has really good reviews, but with the way my oil level is going up at the moment I'm 99.9% certain my next car will be petrol and the skyactiv-g seems to have been less well received and doesn't really seem to be the revolutionary step forward that the diesel is. Other manufacturers seem to be doing a much better job with improving the efficiency and refinement of petrol engines (for example, the new A3 1.4 with cylinder deactivation claims 140hp and 60mpg). I'm hoping for similar technology in slightly more powerful engines before I replace my car (looking forward to more details of the new Seat Leon at the Paris motor show...).
