The easing of the White House plan stems from a concession to makers of light trucks and SUVs, and particularly larger vehicles in that segment, such as Ford's F-150, sources said. The latest White House proposal, the most definitive of any it has put forth, calls for a 5 percent annual mileage increase for cars from 2017-2025, said industry and congressional officials who asked not to be named because their discussions with the White House are confidential.

But it’s starting to look like Mercedes may be bucking the trend with slightly surprising plans to take a V12 version of the new SL to the New York Auto Show next month – the Mercedes SL 65 AMG.
