Noob question
For the uninitiated, I would like to better understand the key differences between the 4.2 V8 A8 and the S8.
From what it obvious :-
The engine has had a tweak to give it the extra bhp but is it just ECU mapping or are there differences in the engine, exhaust, etc?
I gather the S8 has 4 pot Brembo front calipers with 345/30 discs.
Suspension wise, presumably bigger ARBs and better shocks/springs?
Anything else...?
Thanks in advance
