Unlike the RS4's 4.2 engine, this new V8 doesn't actually sound or feel anything like a V8. As has been discussed many times before if they tried to build a 4 litre 6-cylinder engine they would have ended up with much larger pistons which would not have been able to attain the kinds of piston velocity that is the M-Division trade mark.
