The second-generation Audi S8 is the epitome of a wolf in sheep's clothing. The full-fat 5.2-litre V10 motor - a derivative of the same engine you'll find in the Lambo Gallardo - produces no less than 444bhp and 398lb ft of torque. Despite its near two-tonne kerb weight, it's good for a 0-62mph sprint time of just 5.1sec and a top speed of 155mph (limited).
While the standard car growls and sings rather nicely, the S8 you'll hear in this video barks, pops and cracks as if it's just been driven out of the gates of hell by Satan himself.
The reason? This S8 comes fitted with a new Meisterschaft exhaust system (stainless steel by the looks of it), which has given that engine a very, very bad lease of life. Watch, listen, leave us your thoughts.
