Could Synthetic Fuels Save The Internal Combustion Engine?

Automakers like BMW and Porsche are investigating synthetic fuels as a way to keep internal-combustion engines alive in the face of stricter emissions standards. But Engineering Explained host Jason Fenske is skeptical of this new fuel technology.

While gasoline and diesel are refined from naturally occurring stocks of crude oil, synthetic fuels are made by combining different molecules into a substance that performs like a conventional fossil fuel in a combustion engine.
