The word

Ford has improved the fuel economy of its gasoline engine F-series trucks by 15% and its diesel engine trucks by 25% thanks to improvements in both engine technology and a new transmission.
The 6.7L Power Stroke V8 diesel (turbocharged) averages 18% in fuel economy improvements and 25% for chassis cabs over the 2010 models. The 6.2L V8 gas engine delivers 15% over its 2010 counterparts.
Both are mated to a new 6R140 heavy-duty TorqShift 6-speed auto-transmission which is credited with much of the boost to overall efficiency, especially at highway speeds.
And so ...
With pickups still one of the largest segments in U.S. sales, improvements like this are excellent news.
