Hydrogen as a car gas, significantly hydrogen as a flamable relatively than as part of a gas cell system as in a Hyundai Nexo or Toyota Mirai, is form of contentious. It’s not a brilliant environment friendly approach to make energy, and whereas Toyota is tinkering with the expertise in race automobiles as of late, BMW tried to make it a factor within the early aughts with the Hydrogen 7.
What’s the Hydrogen 7, and why have you ever most likely not heard of it, and, extra importantly, how dumb of an thought and implementation was it approach again in 2005? Well, fortunately, we have now Engineering Explained’s Jason Fenske to assist us with these final two components.
As you’ll see, BMW made a number of actually bizarre decisions that required some main sacrifices that no person would have been keen to reside with in the actual world, particularly not with a V12-powered luxurious land yacht that was already based mostly on an unpopular platform (Bangle Butt E65, anybody?). Things like a vacuum-insulated liquid hydrogen tank that empties itself over the course of 10-12 days of sitting, which additionally meant that this massive boy wasn’t imagined to get parked indoors.
The lack of energy in comparison with the common gasoline V12 was fairly egregious too, however what was extra egregious had been BMW’s spurious claims as to the hydrogen unit’s efficiency and vary. It was a neat proof of idea, however it’s one which the advertising division shouldn’t have been allowed to run with.
If there’s a pot of gold on the finish of the rainbow, it’s that Sreten from M539 Restorations on YouTube is taking the lengthy block from considered one of these Hydrogen 7 V12s and utilizing it in a efficiency construct on a six-speed-manual E31 BMW 850i, and E31s are at all times cool.
