Used 2020 Ford F-250 Super Duty Diesel

How does it drive?

The Ford Super Duty is comfortable, quiet and, if you get either of the optional powertrains, effortless to drive. The 6.7-liter diesel and 10-speed transmission might just be the most enjoyable powertrain combo that's available in this class. The relentless torque and surging-but-butter-smooth power delivery are worth the cost of entry alone — and the gargantuan towing figures are just icing on the cake.

As far as the 7.3-liter V8 goes, it's impressive, sure. It's quieter than the diesel at idle, but it doesn't accelerate as hard as you'd expect from such a giant engine. Power is a bit more immediate at slow speeds, but that's about the only place it sees an advantage.

At highway speeds, you don't get too much rumble from the diesel engine or the 7.3-liter V8. Road noise is always present, and it's louder than average when you go with the Tremor because of its off-road tires. Wind noise is ever present too, especially with the big towing mirrors, but this is typical for the heavy-duty truck class.

Both the F-250 and the F-350 feel confident around corners, especially considering their mass. Steering is as you'd probably expect from such a big truck: numb. But the steering wheel resistance loads up well as you go around corners, and the hefty steering wheel feels good in your hands.

Go with the standard FX4 off-road package and you'll have an easy time going far off the beaten path. But with the Tremor package, the F-250 reaches a whole new level. The extra ground clearance and impressive approach and departure angles make a noticeable difference. The knobby tires also provide plenty of grip on slippery rock surfaces, and the Tremor's electronically controlled off-road aids (such as the new rock-crawl drive mode) can make even off-road novices feel like a pro.

What's the interior like?

Even though the 2020 F-Series Super Duty receives plenty of upgrades under the skin, it's hard to distinguish between the old and new models. The cabin, for instance, is practically a carbon copy unless you opt for the top-trim Limited. That primo Super Duty now includes additional leather throughout the interior, black ash wood trim, and a faux suede headliner.

A set of newly standard and optional technology and safety features will appeal to owners and businesses alike. Every Super Duty now includes a 4G LTE modem and Wi-Fi hotspot that supports up to 10 connected devices. This tech seems like an unusual feature to standardize on a truck that comes with crank windows, but it makes sense given the Super Duty's popularity in fleets. Ford offers a telematics suite for fleet operators so they can keep track of various vehicle data points, but it's currently only available on Lariat models and above. By including it on every Super Duty, even the fleet-oriented XL can be equipped with the suite.

Ford's Pro Trailer Backup Assist feature is now available on the Super Duty. First introduced in the 2018 Ford F-150, it helps drivers reverse with ease while towing a trailer. Drivers turn a dash-mounted knob to the left or right, and the system rotates the wheel to point the trailer in the correct direction. In our experience, the Pro Trailer Backup Assist takes a while to set up and has a bit of a learning curve, but first-timers will be happy to have it.

A number of advanced safety features are now standard on XLT models and above, including lane departure warning for the truck and attached trailer, automatic high-beam control, a blind-spot monitor with trailer coverage, and forward collision warning with automatic emergency braking and pedestrian detection. The forward collision system and blind-spot monitor are also available on XL and XLT models as part of option packages. Rounding out the tech features are standard USB-C ports and an available wireless charging pad.

How practical is it?

Want to tow? For pulling trailers, the Super Duty is one of the most practical vehicles on the planet. Need to load a few-thousand-pounds-of-whatever in the bed and haul it away from the job site or to the farm? The Super Duty is excellent at that. Feel like parking it at your local grocery store? Well, good luck with that. The 2020 Ford Super Duty is meant to be practical for those with big tasks. You can learn to maneuver it in tight spots with some experience (and help from items such as the rearview camera) but it's unapologetically big — just as it should be. Thankfully, features such as the Pro Trailer Backup Assist will help you place your trailer exactly where you want it.

Edmunds says

New engine options, an updated interior on the top trim levels, and plenty of modern tech help move the Ford Super Duty to the front of the pack. The Ford isn't alone in offering chart-topping capability with near-luxury levels of comfort, though. It faces stiff competition in what is probably the most competitive heavy-duty segment ever.
