The new 6.7-liter diesel V8 that is debuting in the 2011 Ford Super-Duty pickup trucks is the first such engine ever developed and built in house by that automaker. According to Ford, the new engine, which was code named Scorpion during development, is the cleanest diesel ever put into a Ford. It is the first Ford truck diesel with both a particulate filter and selective catalytic reduction (urea injection) for reduced emissions. This is added to a reverse flow (intake on the outside, exhaust in the valley) architecture and a new twin compressor turbocharger.
Compared to the outgoing 2010 models, Ford claims the diesel pickup trucks now get 18 percent better fuel efficiency and chassis cab models (like those used for tow-trucks and flat-beds) get a 25 percent boost. The EPA doesn’t provide official mileage values for vehicles with a gross weight rating over 8,500 pounds. During the recent first drive in Arizona, media averaged anywhere from 20 miles per gallon to as much as 29 mpg on a mixed driving loop with the new diesel Super Duty. The new trucks are also the first Fords officially rated for operation on B20 biodiesel.
