The biggest inefficiency in and internal combustion engine is heat.
About twice the HP of the engine is wasted in heat... So if you had a 100hp car 200hp is lost in heat.
Have you ever seen an exhaust manifold glowing red hot?

If you could capture and use that heat it would make a huge difference in economy.
