I was being sarcastic.It's just ONE factor in what could be MANY factors. Without comparing it with a similar age M5 you can only guess. Who's to say it isn't the higher torque and 9-speed gearbox of the E 63? Maybe the E 63 has been "tuned"? A similar age M5 still may not win. You're drawing conclusions without sufficient evidence. And that goes the same for the E 63 too. Even a half-baked scientist will tell you that these tests are anything BUT scientific.
