Apart from the Zonda engine. Probobly the greatest engine of all time:
1. BMW S70B56
2. 60° 6.1 L V12, 627PS @ 7400rpm, 651Nm @ 5600rpm. Wrapped in gold.
3. Used in the legendary McLaren F1
4. Many and countless compliments.
5. I chose this engine because it's legendary and in my opinion unmatched even to this day, at least the version that sits in the LM version. An engine that is impressive still to this day is a feat in itself. The greatest engine of all time and it's N/A.
