Prototype Hydrogen BMW V12 Engine Teardown - E31 850i - Project Marseille: Part 6

Hydrogen-powered V12 engine. Fascinating thing. In this episode, we learn more about the prototype BMW 7 Series, E38 750hL that BMW made back in the 2000s. I stumbled upon one of these engines that appears to be very clean and very low mileage, so naturally, we take it apart. This engine is going to be the basis for our M73B54 OEM+ build for project Marseille, E31 850i 6-speed.
