Ford F-150's 3.0L Power Stroke Diesel

3.0L Power Stroke Diesel Specs

Ford Motor Company made us wait a long time for a diesel powered F-150, but it finally become available for the 2018 model year. The 3.0L Power Stroke V-6 boasts 250 horsepower and 440 lb-ft of torque from a mere 183 cubic inches, slightly edging out their strongest competitor, FCA’s 3.0L EcoDiesel. Furthermore, Ford's new powertrain combination earned a 30 mpg highway rating, ousting the EcoDiesel by 3 mpg and even passing the midsize Colorado/Canyon twins from GM (based on 2019 model year).

The new diesel from Ford competes primarily with the EcoDiesel equipped Ram 1500, although General Motor's diesel Canyon/Colorado models and possibly the Cummins powered Nissan Titan XD attract buyers from the same pool. The 3.0L Power Stroke marginally surpasses the Ram 1500 EcoDiesel’s 240 horsepower and 420 lb-ft of torque. Ford achieved their 30 mpg target, edging out the EcoDiesel by 3 mpg on the highway (based on 2019 fuel economy ratings).

The F-150 does have a significant advantage over the Ram 1500 in the departments of maximum tow and payload ratings, coming in at 11,400 lb towing and 2,020 lb maximum payload to the 2018 Ram 1500's 9,240 lb tow and 1,600 lb payload ratings. These figures far surpass the Chevrolet Colorado and GMC Canyon's capabilities, but don't quite reach the 2018 Nissan Titan XD's 2,420 lb payload capacity and 12,760 lb 5th wheel tow ratings. The Titan XD, however, is somewhat of an odd platform that, in our opinion, has not and will not pose a serious threat for Ford in the segment.

3.0L Power Stroke engine blocks are manufactured from weight saving compacted graphite iron, similar to that of Ford's 6.7L Power Stroke V-8. Additional weight savings are captured using cast aluminum allow cylinder heads. The 3.0L Power Stroke features a dual overhead camshaft (DOHC) design with 4 valves per cylinder. Particulate and NOx emissions are controlled by routine equipment - a diesel particulate filter (DPF), selective catalytic reduction system (SCR) using diesel exhaust fluid (DEF), and exhaust gas recirculation (EGR).

Engine power is transmitted by a 10 speed automatic transmission featuring a 4.69 to 1 first gear and three separate overdrive gears, the tallest of which comes in at a 0.63 : 1 ratio. It features an integrated electric fluid pump that permits the use of stop-start technology. But despite the transmissions complexity and sophistication, it requires maintenance only at 150,000 mile intervals.

3.0L Power Stroke Diesel Horsepower and Torque Curve

At full load, peak engine torque is produced at 1,750 rpm and, according to Ford's torque curve, is maintained until 2,250 rpm. It then appears to taper off slowly as horsepower builds steadily through 3,250 rpm.

* 4x2 models, max MPG available. F-150 models equipped with the 3.0L Power Stroke had not yet been rated by the EPA at time of publishing and thus Ford's "target" mpg was use for comparison purposes.

The diesel powered F-150 leads the pack in fuel economy but won't be the mule in the platform's workforce - both the 5.0L and 3.5L EcoBoost equipped trucks feature higher (albeit marginal in some instances) payload and tow capacities. This is due in part to the diesels additional weight; despite its CGI engine block and aluminum cylinder heads, the diesel comes with additional heft from its DEF tank and emissions equipment. Neither come close to the Power Stroke's targeted fuel economy and thus, in a sense, the Power Stroke is an economical balance between weekend warrior and daily driver (negating its premium over gas engine options).

The new Power Stroke outshines the other engines in low end torque, peaking at 1,750 RPM and maintaining its peak torque through 2,250 RPM, at which point it drops favorably slow as it approaches the top end of its operating range. The 10 speed transmission is standard on the Power Stroke, 2.7L EcoBoost V-6, 3.5L EcoBoost V-6, and 5.0L V-8, meaning that three of Ford's four gas engine options take advantage of its three overdrive gears to reduce engine RPM under cruising conditions and maximize fuel economy.
