2020 Diesel Heavy Duty Truck and Van Buyer's Guide
We're now several months beyond the September 2019 announcement of Ford's '20 Super Duty pickup, and the all-new 7.3L (gas), and third-generation 6.7L Power Stroke (diesel) V-8 engines that power it.
While initial details focused on the highlights of both engines, the diesel's advertised torque is the statistic that immediately set the Internet ablaze with comments and speculation about maximum-towing capability, and the 6.7L's overall performance potential. Blue Oval's 1,050-lb-ft proved to be the decade's (unofficial) final statement in the Big 3 truck manufacturers' ongoing efforts to one-up each other in the battle for horsepower (the new Ford puts out 475 hp), but moreso, torque supremacy.

One thing that's important to note is that manufacturers' engine-output statistics are typically presented as "crankshaft" data that is recorded by an engine dyno. However, while those values are plenty legitimate, a truck's power and torque "at the rear wheels" is the information that matter most to enthusiasts and potential buyers.
Truck Trend was given an opportunity to put a '20 Ford F-250 Limited through rigorous tests as part of its Pickup Truck of the Year program; an evaluation in which the 6.7L-powered rig prevailed as the overall winner.
While detailed specifics and judges' insights on the truck and its performance at #PTOTY are found here, we also have exclusive rear-wheel-performance results, recorded by Tyler Brancifort of North Coast Diesel Performance, using his brand-new (246 miles) Velocity Blue '20 F-450.

The tests were performed on the Dyno Star chassis dyno at Mass Diesel Performance in Bellingham, Massachusetts, with the truck in 100 percent stock trim (the '20 F-450 is equipped with 4.30 gears), and for aftermarket-performance's sake, after baseline runs, a fog of nitrous oxide was introduced to the airflow, to see how the third-generation 6.7L Power Stroke responds to increased oxygen.

Here are the impressive rear-wheel results. Seventh gear was used (selected with the 10R140 ten-speed transmission's manual mode for a direct 1-to-1 drivetrain ratio) for all recorded dyno runs.
