I'm sure that the battery factories and the cost energy and effort from retooling, and switching to more exotic materials every year or two isn't helping much.
Heaven forbid the manufacturers step up to an advanced computer running these things too. How about a 512 MB not BIT or KB computer that uses a fast processor and a wideband, EGT, variable fuel pressure, pulse widths, etc and ambient air to actually make these cars run perfectly in ALL conditions? There are plenty of reports of people taking their time to tune a CARBURETOR on their BIG BLOCK in a '55 Chevy getting 25MPG on the freeway at cruise with an overdrive. many of these cars have 7000-8500cc engines, 400-650 horsepower and can do 0-60 in 3 -4 seconds.
The OEM's are taking their time and trying to make as much money as possible. that's what it boils down to in my opinion. They will most likely get extra government funding within a few years if they can prove that they can't make the goals.
