When you graduate to heavy-duty pickup trucks, towing capacity becomes one of the most important aspects of any truck you may, or may not, buy. Most folks who buy something like a Ford F-350 or a Chevrolet Silverado 3500 HD need a truck that can't shy away from hauling extremely heavy loads. Because of this, the Detroit Big Three spend big bucks on trying to out-do one another when it comes to engine power, towing capacity, and payload capacity.As of 2023, Ford is currently in the lead when it comes to both power output and towing capacity. That year, an all-new iteration of Ford's Power Stroke diesel V8 hit the market, and its power output jumped by quite a bit. Not to mention, its towing capacity reached 40,000 pounds, higher than any factory-produced pickup ever on the market to date. If you need those 40,000 lbs of capacity, you need to take a look at the 2023 Ford F-450 Super Duty. Here's How Much It Costs Cars & BidsFord's Super Duty lineup first hit the market at the turn of the millennium and is now firmly within its fifth generation, which launched in 2023. That same year, Ford took the heavy-duty pickup truck market by storm with the introduction of the 6.7-liter Power Stroke diesel High-Output V8. From the factory, the hopped-up engine could be optioned onto the F-250, F-350, and F-450 Super Duty models. Those who opt for the engine add an extra $2,500 to the truck's MSRP right off the top.These days, a 2023 model-year F-450 Super Duty has managed to retain a good chunk of its value. When it was sold new, the cheapest possible price you could get a High-Output Power Stroke diesel V8-equipped F-450 was about $60,995 for the base-level "XL" trim without any options added on.These days you can find the exact same truck in your driveway for approximately $52,510 on the current used market. While it doesn't seem like much of a difference, that's still nearly $8,500 below the original price. However, when you factor inflation into its original price, it's actually around $66,625 in today's money. So, after some roundabout math, you're saving over $14k by buying used.Cars & Bids At this point, we'd like to do a price comparison between our Ford F-450 Super Duty and some of its main competitors. However, it's not exactly straightforward. The reason being, there simply aren't any apples-to-apples adversaries. The Chevrolet Silverado 4500 HD and the Ram 4500 HD both aren't sold from the factory with a standard eight-foot pickup bed. Instead, most are sold as chassis cabs, and whoever buys one brand-new outfits them with whatever sort of bed or add-ons are needed. How It Makes All Its Power Cars & BidsThe High-Output 6.7-liter Power Stroke diesel V8 builds its power off the bones of the standard engine. This means the core of the motor is the same, such as its Compacted Graphite Iron (CGI) block. It also boasts a nearly indestructible pair of heads featuring six head bolts per cylinder. The mill's fuel system is also the same, along with the turbocharger itself. In its standard iteration, the current Power Stroke diesel V8 produces 475 horsepower and 1,050 pound-feet of torque.However, to get the powerplant to squeeze out an extra 25 hp, Ford engineers did just a little bit of fine-tuning and part-swapping. For starters, the High-Output variant comes with an improved state of tune, which shoots just a little bit more fuel into the combustion chamber. In addition, its cooling system is slightly improved for better high-demand performance. Its exhaust manifolds are also slightly altered, having a more performance-oriented design that dissipates heat more reliably. How The Rest Of The Truck Gets On Cars & BidsHandling the High-Output Power Stroke's massive gob of torque is a 10-speed automatic transmission. It's called the "10R140", and it's the most robust gearbox built for a civilian Ford model. As for drivetrain, the F-450 Super Duty can be optioned with either rear-wheel drive or four-wheel drive, with the former serving as the standard setup for base models carrying the XL trim.On all F-450 models, a unique wide-track front axle is featured that's meant to improve its turning circle over F-350 Super Duty models. Its suspension consists of a live rear axle supported by 10 leafs on either side. Up front is also a leaf spring setup.When properly equipped, the F-450 Super Duty can tow up to 40,000 lbs, a best-in-class number. However, it's not as simple as hooking that much weight up to its trailer hitch. The 40,000-lb capacity refers to the amount of weight it can handle when using its in-bed-mounted gooseneck or fifth-wheel hitch.Those who are simply looking to hook a trailer on the rear-mounted hitch and go can expect a maximum towing capacity of 30,000 lbs. Its payload capacity can reach up to 6,482 lbs, again when properly equipped. How Ford's Power Stroke-Powered Super Duty Came To Be Bring A TrailerIn 1999, Ford unleashed its Super Duty lineup as a standalone model for the first time. Prior to its release, the Super Duty namesake was reserved for trucks that were destined for a dedicated purpose, such as a stakebed or flatbed assignment. However, Ford was looking for a way to better differentiate its heavy-duty lineup from the standard F-150 and, at the time, F-250 models. When it debuted, the Super Duty lineup consisted of the F-250, F-350, F-450, and F-550 trucks.Ford's gamble on differentiating its trucks ended up paying off, as the Super Duty quickly became America's bestselling heavy-duty truck. In the early days, and until 2003, the Super Duty also had the privilege of offering one of the most iconic and famously reliable diesel engines to-date: the 7.3-liter Power Stroke diesel V8. That engine, coupled with the Super Duty's good looks and capable specs, carried the name straight into the spotlight, where it remains to this day.Bring A Trailer Over the years, the Ford Super Duty suffered some slight hiccups, especially during the late 2000s and early 2010s. At the time, Ford had begun offering the infamous 6.0-liter Power Stroke diesel V8 halfway through the 2003 model year, which ended up being a PR disaster for heavy-duty Ford trucks thanks to the mill's popularized unrelibaility. The engine that followed it, the 6.4-liter twin-turbocharged Power Stroke diesel V8, wasn't much better in terms of dependability.However, in 2011, Ford launched its current diesel engine, the 6.7-liter. There were some teething pains early on, but these were, reportedly, sorted by 2012 or so. Since then, the mill has undergone several changes to keep it relevant in today's diesel world, including the introduction of the 500-hp High-Output version.
