This is an interesting article which describes what has been mentioned here before; Nissan claims it's made a more thermally efficient gas engine, but there's a catch. Apparently Nissan has been offering it for about 5 years, just not on this side of the pond.
A couple of things which weren't mentioned; they've been doing this with locomotives for years, sans the battery. And what's more efficient than a gas engine? The same engine which is powering many of our tractors.
