I'm from Austria and I'm still driving a VW Corrado
but I would like to get the A8 from Germany soon, as I like this car incredibly well. I still have the problem that I want to gain more general knowledge, so no detalized questions can ask and hope that you can help me and that I am wanted here than not A8 - driver 
So for the time being I want to make sure that I got the right idea that there is the A8 with the following motorizations:
- V6 2.5 TDI (179 hp)
- V6 2.8 Benz (193 hp)
- V8 3.3 TDI (224 hp)
- V8 3.7 Benz (don't I know 240? PS)
- V8 4.2 Benz (310 hp) / S8 (360 hp)
It would be important if I knew which motorizations there are, so that I can decide so half way in the VOrfeld. I would still be interested to know how difficult the lightest and the heaviest are with this also about the guideline. Can I also read somewhere like the individual of consumption/acceleration etc. I would also be very interested. Of course, I would like to get the S8, but in Austria the insurance is not quite so cheap. Is there a page or so where I can read the whole general something?
Thank you already in advance
