Serious question time: Do the auto manufacturers actually have in their R&D pipeline engines that achieve California's 54.5 mpg target that they can bring to market before 2026? Europe's measuring standards are very different from here and the "80-mpg" economy figures you see touted actually work out to be more like 50 real world...similar to what happens here. Auto manufacturers aren't set to increase standards for the EU until 2030.
