The unique 6.5-liter V12 was developed by Cosworth, who was more than happy to share a few details with Carfection and let them record the engine’s sound on the dyno. Needless to say, it sounds phenomenal.
The angry buzzsaw-like soundtrack will definitely remind you of some older Formula 1 cars, back from the days when F1 engines sounded epic.
Bruce Wood, Cosworth’s managing director said that the process of creating this jewel of an engine started with an existing four-cylinder design they already had in order to speed up the development time. The company then designed a three-cylinder head for that engine, replicating three cylinders of the V12’s final form.
Since the finished item would feature four catalysts (one for each three cylinders), Cosworth worked on their three-cylinder engine to see if they could deliver on the targets set for power and emissions. Within five months, they had a naturally aspirated three-cylinder engine that made 250hp and passed emissions tests.
Another fascinating fact is that the engine is also a structural part of the Valkyrie, with Wood saying that engineering the correct mounts was a huge task. If you want to see on some of the Valkyrie V12’s gorgeous details, or just want to hear this beast roar, head to the video linked below.
