Video Description

I went to the Italtecnica workshop in Northern Italy to find the most powerful road car engine in the world – the Giamaro 7.0-litre quad turbo V12. Rated at 2,000hp, this brute of an engine is now out-performing both Bugatti and Koenigsegg. I delve into its geeky engineering, as well as nerding over the other beautiful engines in Italtecnica's workshop.
