Since the proposed 2025 CAFE standards are, well, proposed, VW still hopes to negotiate some modifications before the fuel economy guidelines become official. Jonathan Browning, chief executive officer of Volkswagen Group of America, told Ward's Auto (sub. req.) that, "We still have a dialogue going on with the administration in terms of how we think the policy needs to be adjusted."
VW says the current proposed rules allow "special compliance flexibility for heavier light trucks" while placing too high a burden on passenger cars. More specifically, VW cries foul, stating, "The proposal encourages manufacturers and customers to shift toward larger, less-efficient vehicles, defeating the goal of reduced greenhouse-gas emissions."
Diesel engines, according to VW, are ignored by the proposed rules. Clearly, that statement isn't true, but the German automaker argues that since diesels are growing at twice the rate in terms of U.S. sales compared to electric and hybrid vehicles, oil-burning mills, "should be part of the landscape going forward." As we see it, even though VW says its diesel mills should be given preferential treatment for being superior to an equally fuel-efficient gasoline engine, that's just not how CAFE works.
