White House pushes automakers toward 54.5-mpg target by 2025

The White House is pushing automakers to agree by Wednesday to a corporate average fuel economy target of 54.5 mpg by 2025--a figure 1.7 mpg less than the 56.2 mpg standard it floated earlier this month. 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.

Aston Martin V12 Zagato: First production car photos

Ahead of a debut in Kuwait in two weeks, we have the first official photos – interior and exterior – of the production version of the Aston Martin V12 Zagato.  So far we’ve had just one outside picture of the production version of the Aston Martin V12 Zagato, and we know that it will make its production debut at the Kuwait Concours d’Elegance on 15th February. But now we’ve got more pictures. Aston Martin has quietly published a PDF on the V12 Zagato (link to Aston Martin V12 Zagato PDF) which gives us some of the history behind the development of the V12 Zagato, tells us how it’s made (with craftsmen and hammers) and, for the first time, gives us a look at bothy the inside and outside of the new Zagato.
