Ford F-150 With Power Stroke Diesel EngineWe’d be hard-pressed to choose a single best diesel engine to ever power a diesel truck, but there are certainly a few we’d immediately put forward for that honor — it goes beyond just Duramax, Cummins, and Power Stroke — and they each have their own strengths and drawbacks.

Top Contenders for Best Diesel Engine in Trucks

  • Chrysler 3.0L EcoDiesel: Making up to 240 hp and 420 lb-ft of torque, the small but potent EcoDiesel has been seen in SUVs like the Jeep Grand Cherokee and trucks like the Ram 1500. It’s also the industry’s only light-duty diesel engine.
  • Cummins 5.9L: Making up to 215 hp and 440 lb-ft of torque, this 12-valve Cummins engine kickstarted the modern turbodiesel-pickup movement. It was the first to be a truly viable alternative an alternative to Dodge’s big-block V8 gasoline engine.
  • Cummins 6.7L: Making up to 385 hp and 865 lb-ft of torque, the latest high-output 6.7L offers the most torque ever available in a non-specialty pickup truck. It’s also a common choice at Diesel Power Challenge events.
  • Duramax 6.6L LBZ: Making up to 360 hp and 650 lb-ft of torque, the Duramax LBZ is one of GM’s best diesel engines for pickup trucks, mostly because it’s a modifier’s dream and beats its competitors in horsepower and torque output.
  • Duramax 6.6L LML: Making up to 397 hp and 765 lb-ft of torque, the LML is seen in Chevrolet and GMC 2500HD and 3500HD pickups. Everything from redesigned oiling strategy to next-level PCM calibration helped boost performance, and it’s also the cleanest Duramax to date.
  • Navistar/Ford 7.3L Power Stroke: Making up to 275 hp and 525 lb-ft of torque, this legendary powerplant adopted a no-nonsense attitude that makes it one of the top-performing workhorse engines around.
  • Ford 6.7L Power Stroke: Making up to 440 hp and 860 lb-ft of torque, Ford’s own Power Stroke features a large, single variable-geometry turbocharger, 19mm injector tips, and new “Cobra Head” downpipe to deliver exceptional performance.
