On a company perspective, our job, as well as the job of other companies, is that we have a fleet performance obligation. It is not per vehicle; each vehicle has to meet standards, yes, but we also have to look at how our fleets perform. There are going to be incremental changes across a lot of vehicles right now, such as eight-speed transmissions or nine-speed transmissions, which will make incremental improvements to the fleet, but that will give the benefits of huge changes, game-changing technologies, for a few vehicles. We have to get in that first.
On the fleet perspective, as Dr. Frise mentioned, we have this CAFE or GHG obligation of almost 54 miles per gallon in the future. That is the manufacturing obligation, but in the whole scheme of things, you also have to look at the fuel itself.
We can run on gasoline or natural gas or whatever it is, but what is the life cycle of that fuel? Is there a better way to process that fuel? You can make diesel from biomaterials. You can make methane from biomaterials. How can we do ethanol with second-generation? It's a very encompassing view on how we bring that technology out there, and there will be those increments.
For hybrids and electric, given the standards, we have to get there in some form. It could be a range-extended electric vehicle still having small gasoline power to it. It could be electric vehicles; we've announced a Fiat 500—
