"Porsche will explain in great detail that the new model is 4.5% stiffer than the previous one and 5.8 grams lighter because it has titanium wheel nuts, but those are not the sorts of fact that work well when you are competing for viewers with House of Cards and Billions and a lot of grunting sex on Sky Atlantic. I’m afraid it’s the same story with any AMG Mercedes. It may be a tiny bit quicker from zero to 62mph than the previous model, and the Comand system may allow you to check how economically you’ve driven over the past 30.8 miles. But all of this is overshadowed by the thunderous noise and the massive wiggly back end."
