The story is about the B-A-T-T-E-R-Y, not a C-A-R.
The BATTERY is a new type of rechargeable ("secondary") battery that has much greater capacity than current battery types.
This has NOTHING to do with an engine, gasoline or otherwise.
It may very well be installed in future hybrids, but that is a moot point to this article/discussion.
Sounds like they're talking about cars to me.
Does Toyota have a non-hybrid, all electric, car nobody knows about? ....that travels 120 miles per charge?
If so, please share the link.
