3.2L Power Stroke Diesel

Ford Transit Inline 5 Diesel Option

Ford Motor Company introduced the 3.2L Power Stroke diesel for the 2015 Transit. The engine is an adaptation of Ford’s European DuraTorq platform, but with revisions that make it compliant for use in the United States, including an advanced selective catalytic reduction system and combination diesel oxidation catalyst/diesel particulate filter. It is targeted towards customers who need an economic alternative to the current lineup of gas engines, though the Power Stroke’s fuel economy is not required to be advertised. The inline 5 cylinder Power Stroke produces 185 horsepower and 350 lb-ft of torque; Ford’s specifications suggest peak torque is maintained from 1,500 to 2,500 rpm.  Backing the engine is Ford’s 6R80 six speed automatic transmission, which features two overdrive speeds. Ford of Europe’s DuraTorq is only slightly more powerful than the Power Stroke, which is surprising considering the extensive emissions equipment required to meet Federal and State level emission laws in the U.S.

There has been much speculation that the 3.2L Power Stroke may indeed find its way into the Ford F-150, although solid clues as to the possibility have yet to surface from any official source. The inherent problem with this concept is that the Power Stroke is slightly underpowered for the half ton application, which would limit it to being an option for favorable fuel economy, but at the expense of reduced capability. Considering that the Power Stroke is currently used in a commercial vehicle, it is likely detuned to more conservative power levels in an effort to maximize fuel economy. However, meeting emissions regulations while maintaining fuel economy standards and increasing power to attract prospective buyers presents a series of challenges for Ford if they wish to pursue such a feat in the future. Alternatively, rumors are surfacing that the F-150 will eventually be powered by an engine from the company's "Lions" engine platform.
