...okay, not really. You won't be shocked at all. https://www.epa.gov/sites/productio...mte-final-determination-notice-2018-04-02.pdf Ford: "Various comments raised questions about how to predict the impacts of the standards on vehicle sales. The Alliance and NADA argued that EPA has not yet conducted an “appropriate analysis” of the sales impacts of the standards, and NADA asks the agencies to “fully understand” consumer vehicle purchase decisions. The Alliance referenced work by Ford suggesting that the standards would reduce sales volumes by four percent using cost estimates from the draft TAR. Other commenters provided that neither EPA nor NHTSA has found vehicle demand modeling methods robust enough to predict sales impacts; and EDF stated EPA and NHTSA could consider using a static forecast (that is, assuming market shares to be unaffected by the standards)." Toyota: "Toyota provided comment that “compliance with the current requirements through the 2025 MY require gasoline hybrid electric vehicles or more sophisticated forms of vehicle electrification at sales volumes significantly higher than the agencies’ estimates and at levels the market is unable or unwilling to support absent significant changes in market signals.” Toyota further provided that they continue to disagree with EPA’s past assessment that lighter, more aerodynamic vehicles powered by less expensive conventional gasoline powertrains will be sufficient to comply with the standards." "Toyota’s information stated that “[n]ot yet implemented technologies, such as advanced cylinder deactivation and 48V mild hybrid systems, can play a role in improving efficiency and reducing CO2 emissions moving forward; however, we do not project these technologies as sufficient to meet the 2025 MY requirements.” Fiat: Fiat Chrysler Automobiles (FCA) similarly indicated, “FCA continues to provide data that shows more technology is necessary than the agencies have assumed for 2022-2025MY compliance. The advanced technologies needed, including higher levels of electrification will negatively affect affordability, lowering sales, and ultimately impacting jobs.” Mercedes: "Mercedes Benz estimated that it will need more than 25 percent battery electric vehicles (BEVs) and around 5 percent PHEVs in its fleet to meet the standards in MY 2025, noting that these estimates are significantly higher than the 7 percent BEV and 3 percent PHEV shares projected by EPA for the overall fleet." Mitsubishi: "Mitsubishi expressed concern that it would have to add electrification to already efficient low-priced vehicles and the increased price could drive buyers to less efficient used vehicles."
