Autospies ran a story last week that the S8 isn't quite what it may appear to be. In a nut shell they said despite the 444 horse Lambo sourced engine, it can't touch the acceleration of an AMG Merc, and despite the change to 40/60 torque split and the performance suspension, it can't touch the handling of the M5 (no big surprise). They did say the interior, as always with Audi, is top notch and the ride quality is well preserved. In other words, the S8 is more comparable to a 760i than an M5 despite the V-10 engine and impressive wheels.
