This video from AutomotiveTV shows how a Ferrari V12 engine is made. Ferrari is world renowned for their big engines and meticulous design and manufacture. Every Ferrari off the line is a work of art made largely by hand by craftspeople who take great pains to ensure it’s as perfect as it can be.
The video starts with the casting of the major engine parts: block, heads, etc. Then these are scrutinized, cleaned, modified, and carefully detailed before being assembled together into a working V12 powerhouse.
