Given that Ford worked on direct gasoline injection combustion engines for >40 years before having them reach production (Yeah, M-B had done it in the 300SLs in the 50’s), Fusion might take a few more decades before reaching commercial success.

Agreed. Probably about 20 years. Sadly, I am no longer sure America, the only nation with the skill set to get there, will last the long. Sigh.

/Sorry, Putin, Brussels, and Japan, that is the truth. (No others are in the running.)
