3.0 Powerstroke 2018-2021

The 3.0-liter V-6 has an international pedigree. Commonly referred to as the Lion engine, it was jointly developed by Ford with PSA Peugeot Citroën years ago and is currently used in some Land Rover products. We previously detailed how Ford beefed it up for domestic truck duty, but here's a brief refresher: The block is a compacted graphite-iron casting, and new components include a forged crankshaft with specific rod and crank bearings and a variable-geometry turbocharger. The common-rail fuel injection runs at 29,000 psi, while twin fuel filters and a dual-stage oil pump address purity and lubrication issues. Although its 250-hp figure may seem a little weak in the knees, it's the 440 lb-ft of torque that is of interest to those who work their trucks hard. A 10-speed automatic is the sole transmission option.
