3.2L Power Stroke Diesel

Ford 3.2L Power Stroke I-5 Engine Specs & Information

The 3.2L Power Stroke is an inline 5 cylinder turbodiesel produced by Ford Motor Company and is an asset of Ford's global operations. The engine was offered in the Ford Transit van (cargo and passenger series) from 2015 to 2019 and did not return the Transit's engine lineup for the 2020 model year. It is an adaption of the DuraTorq engine platform, which Ford manufacturers primarily for European applications. Many of the subtle differences between the U.S. 3.2L Power Stroke and European 3.2L DuraTorq were necessary revisions in order to meet strict emissions regulations in the United States.

The 3.2L Power Stroke was targeted towards customers whom required an economic alternative to available gas engines. It produces a peak 185 horsepower and 350 lb-ft of torque; 90 percent of peak torque is maintained from 1,500 to 2,500 RPM at full load. The 3.2L Power Stroke is coupled to Ford's 6R80 six speed automatic transmission, which features dual overdrive ratios. There was no official statement from Ford Motor Company regarding the retirement of the engine from the Transit; it was the lowest powered engine offered in the Transit from 2015 to 2019, with the 3.5L EcoBoost being the highest rated engine option at 310 horsepower and 400 lb-ft of torque. For 2020, the 3.7L V-6 gas engine was also dropped from the list of available engines, being replaced by the 3.5L V-6 (naturally aspirated, non-EcoBoost).
