Well, from experience, I can say, the only thing I do not like about Diesels is the sound (and the fact that they need external heaters to get the cabin warmed up). If you pair a modern (European) Diesel with a proper gearbox, for example a DSG, you will be in full grunt mode all the time and still save a lot of money on fuel. I mean hey, my dad runs a "tiny" 130hp TDi in his A6, 5 speed manual. On the Autobahn, it uses ~5l/100km when driving normally, on my 240km run averaging 197km/h I used 9.2l/100km. Can't really argue with that.....then again, from the driving point, I just love engines like BMW's i6 petrols, the sound they make is just heavenly
