Can I just impart a small measure of disgruntlement. Something's not right here. In the category above 4 litres am I to believe that the extraordinary 6.2 litre AMG V8 engine only comes fifth?

Lightweight and compact, undersquare, bonkers power and torque, a soundtrack to die for; this AMG engine is as charismatic as it is versatile and ubiquitous. It does superb duty in a CLS 63 as it does in an ML 63. It ought to come in in second or third place, objectively, because in my humble opinion it is the best V8 engine in the world. By no means do I agree with its ranking.
