BMW'S HYDROGEN V12 ENGINE IS A HILARIOUS ENGINEERING STUNT

EV Channels Review

This video delves into the ambitious BMW Hydrogen 7, a dual-fuel V12 sedan based on the 760i, capable of running on either liquid hydrogen or gasoline. While BMW touted it as progress without compromise, the reality presented is a significant performance deficit when running on hydrogen, with power dropping from 438 hp to 260 hp due to the use of port injection instead of direct injection. The storage of liquid hydrogen at -253°C presents considerable challenges, including boil-off that necessitates venting, limiting the car's ability to be parked in enclosed spaces and resulting in a usable hydrogen range of only 125 miles. Despite these drawbacks, the reviewer highlights BMW's extensive safety testing, including extreme fire exposure, and commends the engineering effort and risk-taking involved in developing such a novel, albeit ultimately impractical, vehicle. The video concludes by noting BMW's shift towards gaseous hydrogen in fuel cells and electric vehicles.
