After more than a decade of teasing, Ford Motor Company finally introduced a diesel engine option to their flagship F-150 truck line. The 3.0L Power Stroke is a narrow 60 degree, six cylinder vee engine based on the Ford Lion engine platform, which is employed in various European applications. At its peak, the engine achieved up to 22 mpg city and 30 mpg highway fuel mileage, as rated by the EPA.

It competed with the long running 3.0L EcoDiesel produced by FCA and the 3.0L Duramax available in Chevrolet and GMC vehicles. Producing a peak 250 horsepower and 440 lb-ft of torque, the 3.0L Power Stroke trailed both its closest competitors in horsepower, torque, and fuel economy figures (albeit by a small margin). The 3.0L Power Stroke was available in various trims and drivetrain configurations with the exception of the 2021 model year, in which is was only offered in four wheel drive trucks.

Ford Lion Engine Family

Ford's "Lion" engine family includes a pair of V-6 engines produced in 2.7 and 3.0 liter displacements in addition to a pair of V-8 engines displacing 3.6 and 4.4 liters respectively. When news broke that Ford was considering a Lion engine for the Ford F-150, many speculated that the V-8 would be chosen due to its higher power ratings and the importance that performance holds with truck buyers in the U.S. The smaller 3.0 V-6 was ultimately chosen, likely because the larger V-8 could not compete with the fuel economy ratings of competing products in the segment. Lions diesels can be found in various European applications, including cars and small SUVs from Citroën, Peugeot, Jaguar, and Land Rover.

3.0 Power Stroke Retired After 2021

Ford Motor Company's ultimate statement regarding the dissolution of the 3.0L Power Stroke engine option within the F-150's lineup was that the EcoBoost engine platform was exceedingly popular with buyers and the Power Stroke's low sales figures were the source of its demise. While this is presumably accurate, the larger story may be that the 3.0L Power Stroke was not a leading engine within its class; General Motors was leading in horsepower and fuel economy while Ram was leading in torque.

Although it was a close race in the domestic market, Ford was coming in last place. Certainly, the automaker had the capital to invest into the little Power Stroke and dominate the segment, but if EcoBoost powered trucks are outselling the diesel three to one there is little incentive to invest in market domination. For comparison, one could argue that Ford dominates the 3/4 and 1 ton segment with its 6.7L Power Stroke, which has boasted best-in-class titles repeatedly.

The shortcomings of the 3.0L Power Stroke may very well be competing products within Ford's own portfolio, and although we're sad to see it go it doesn't appear that Ford was prepared to give it the attention that it needed to flourish.

[1] - 3.0L Power Stroke only available in 4 wheel drive configurations for the 2021 model year.

Since the 3.5L PowerBoost is a full hybrid, it's not necessarily fair to assess the Power Stroke's strengths and weaknesses against this powertrain configuration. However, the long running 3.5L EcoBoost remains the F-150's crown jewel and for the 2021 model year produced a peak 400 horsepower and 500 lb-ft of torque; 60% more power and 14% more torque than the 3.0L Power Stroke. While the diesel offers a significant improvement in highway fuel economy, its combined figures are only 3 mpg (~13%) greater than the EcoBoost powered F-150. Would the average truck buyer sacrifice 60% greater horsepower for a 13% improvement in average fuel economy?

Note that at the time of the Power Stroke's retirement, the EcoDiesel led the segment in torque, the Duramax led the segment in horsepower and fuel economy, and the 3.0L Power Stroke failed to claim any best-in-class positions during its tenure. From a competitive perspective, this niche segment is a close race; all two wheel drive vehicles achieved a minimum 30 mpg on the highway and all four wheel drive vehicles were within 1 mpg of each other in highway and combined fuel economy averages.

Horsepower & Torque Curves

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.
