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.

The 3.2L Power Stroke is targeted towards customers who require an economic alternative to the current lineup of gas engines. 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 ratios. Upon reception, there was much speculation that the 3.2L Power Stroke would find its way into the Ford F-150 platform. However, Ford has since released the 3.0L Power Stroke for F-150 applications and there are no plans to offer the inline 5 cylinder in Ford's best selling pickup.
