Let me answer each point made by you as best I can.
Firstly agreed we don't rally our cars every time we take them on the road, but the point was more that awd is the choice of all leading manufacturers so proves it advantage over rwd especially on road use and in all weather conditions. As for easier power on corrections,
hello, if you have ever watched the FifthGear video of the M3 vs RS4 you will see the M3 produced a 38degree slid angle where as the RS4 recovered from a 90degree slid angle, now which is the easier to power on correct.
Secondly Porsche reference was used to prove that you don't need 50/50 weight balance to produce a perfect driving experience. As for your argument that BMWs understeer less than Audis do because of this perfect balance you talk about. Audi engineer understeer in for safety, something that BMW are starting to do, fwd or awd don't have to understeer because of this weight balance, the Integra Type-R doesn't and neither does the EVOs, it is Audi's choice to have understeer something I think most people are thankful of.
Thirdly the S6 vs M5 debate. As I have already said the S6 can't match the M5 on out right performance but on a recent test around a test track it all but matched the M5 and all this with an extra 150kgs and 80 less horsepower. If you put the test to a twisty road where there is no run off areas or gravel traps then yes I do think the S6 will be more than a match for the M5. You keep forgetting that most of the people who buy this cars aren't Arton Senna etc, they are normal and this is where the extra safety and confidence of awd pay big time and no 50/50 weight balance, rwd or all the might of your Ultimate Driving Machine will ever beat that.
And lastly you say that the S6 shouldn't be in the same leagues of the M5 or E63amg, well you are back to your pub figures argument, mines quicker than yours. If that's your only defense then you can keep your M5 etc and good luck to you, but no thanks I prefer quality not quantity.
Sticky, I don't know where all this argumentative side has come from but at last count I think you has got the back up on about 6 people and that's the ones that are replying to you. Take some QuietLife and watch some fish, you really need to take it easy.
