2020 Diesel Heavy Duty Truck and Van Buyer’s Guide

Four-Digit Torque Is Here

Austin Lott
Oct 28, 2019
Well, everyone, the day has finally come: 1,000 lb-ft of torque can be had straight off the showroom floor, and two out of the three -ton pickups achieve an astonishing 30-plus-mpg rating from the EPA (one is pending but likely to hit that number as well). For 2020, there is a diesel-powered pickup truck for nearly every possible experience level.
From the Chevrolet and GMC trucks that are light on driver-assistance technology but big on towing capability to the Ford and Ram trucks that heap on the features, this year's diesel segment is more capable and powerful than ever before. Vans have become even more efficient, and, in what we think is a positive sign of things to come, Ford introduces a new four-cylinder diesel engine in the Transit. Diesel is now more competitive, and the vehicles you have to choose from are better than years past.
We detail changes for the 2020 model year in the following pages, in addition to an overview of strengths and weaknesses for each truck and van. Whether you're looking to tow or just want to experience the superior driveability and economy of a diesel-powered vehicle, 2020 is a great year to get out and drive something.

Ford

F-150
Rumor has it there's a bunch of changes coming to Ford's F-150, but not until 2021. We don't expect the truck to change drastically this year, which is certainly not a bad thing. The current F-150 is available with a 3.0L Power Stroke V-6 engine, which makes 250 hp and 440 lb-ft of torque. The smallest Power Stroke is paired with a silky-smooth 10-speed automatic transmission and is plenty capable: maximum trailer towing capacity is 11,400 pounds. However, the F-150 has serious competition from the other -ton pickups: the '20 Ram 1500 and Chevrolet Silverado. All three now offer six-cylinder diesel power.

Notably, the diesel option is now available in the XLT trim level—not just the more expensive Lariat, King Ranch, and Platinum models. Though Ford still doesn't offer the diesel in long-wheelbase regular-cab models, with the expansion to the XLT trim, the Power Stroke is now available in 75 percent of all F-150 variants. Not half bad! Fuel economy is rated at 22/30 mpg city/highway by the EPA. Editors from Diesel Power and Truck Trend have reported real-world mileage in the mid-20s when driving "normally" and into the low 30s when making a serious effort to driving conservatively. Read that again: A -ton pickup is rated at 30 mpg and can tow more than 11,000 pounds of trailer. Though, with the trailer it doesn't get nearly 30 mpg. Driveability of the Power Stroke F-150 is good, though the abundance of torque and relative lack of horsepower is noticeable on the highway, where passing maneuvers are slow.

Pricing for the Power Stroke-powered '19 F-150 starts at $46,225. Starting prices for the '20 F-150 are not confirmed but also aren't expected to change drastically.
Super Duty F-250/F-350/F-450
With the heavy-duty pickup segment really heating up, Ford is upping the ante with its '20 Super Duty lineup, which includes F-250, F-350, and F-450 trucks. The truckmaker asserts that Super Duty, with the 6.7L Power Stroke V-8 engine, will be its most powerful and capable, iteration yet, and that the truck is equipped with an all-new 10-speed automatic transmission. With that being said, Ford has been quiet about exactly how much better the truck is. Last year's Power Stroke diesel produced 450 hp and 935 lb-ft of torque and allowed drivers to pull 21,000 pounds of conventional trailer (or up to 35,000 pounds with a gooseneck hitch). "More capable" could be as mundane as 35,001 pounds of towing capacity, but we're confident Ford will take a serious shot at the current leader: General Motors. Most people probably won't be towing that much, since anything beyond a combined weight of 26,000 pounds (that's the weight of the truck, trailer, and load) gets into commercial driver's license territory.
Despite the marketing hype from Ford, Chevy, and Ram, there's more to these trucks than the headline numbers detailing who can pull what. On the contrary, each manufacturer's heavy-duty pickup offers features that make it a unique value proposition for different buyers. There are four carefully positioned cameras, and a handful of views they enable, giving you more confidence when piloting trucks this big (and expensive). In addition to the 360-degree view of the truck, the Super Duty is the first rig in the Heavy Duty segment to offer Pro Trailer Backup Assist, which allows drivers to twist a knob and back a trailer up, letting the computer take care of the steering part. For pros, it's redundant, but for those just stepping up to the bigger rigs—and perhaps towing—it's a nice feature to have.

Photo 7/52   |   The new Super Duty Tremor borrows a few tricks from the smaller Raptor but splits the difference between capability off the highway and towing on it.
Ford also introduces the Tremor off-road edition on the '20 Super Duty, and, unlike Ram's Power Wagon, the Ford is available with its diesel-engine option. Ford explains in its introduction of the Tremor that customers use their trucks for more than work, so something like the off-road trim makes more sense now. The modified Super Duty rides 2 inches higher, with 35-inch Goodyear tires, and has upgraded shocks and springs. Additionally, the truck gets skidplates, a locking rear differential, and a Dana limited-slip front axle. Selectable drive modes include a Rock Crawl and Trail Control, which is basically off-road "cruise control," a feature borrowed from the Raptor. Pricing for the Tremor had not been confirmed by our deadline.

Prices for a '19 Super Duty start at $43,765 for an F-250, $44,935 for an F-350, and $48,870 for an F-450.
Transit
Ford's Transit van gets a few updates this year, including a new diesel powerplant. The old 3.2L Power Stroke I-5 is discontinued and in its place is the 2.0L EcoBlue compound-turbocharged I-4. Power, torque, and fuel efficiency is claimed to be "more" than the outgoing 3.2L, though Ford had not published specifics by our deadline. The global Raptor Ranger gets a variant of the same engine, which makes 210 hp and 369 lb-ft of torque and is paired with the 10-speed automatic transmission. That's "more" in our book.
Photo 9/52   |   By introducing a new, more efficient diesel engine, Ford has us thinking it is moving in the right direction.
Other notable changes for 2020 include the addition of power-sliding side doors on cargo and wagon versions, in addition to revised grilles. Overall, the minor changes are driven by functionality, even the grilles, which increase airflow. Though an all-wheel-drive system was introduced this year, it is limited to gasoline models. For now. We hope it finds its way to the diesel, which would only serve to widen Transit's reach. Also, thanks to consumer demand, Ford also introduces a Crew Van version of the Transit, combining five seats in the front two rows with an open rear cargo area. Though it's aimed at businesses that want to haul crews and cargo, we see an opportunity for upfitters and the overland segment.

Pricing has not been confirmed for the lightly refreshed '20 model, but a 2019 Transit with the diesel starts at $45,060 for the passenger van and $38,625 for a cargo van.

General Motors

Chevrolet/GMC Silverado/Sierra 1500
General Motors brings a diesel back to the -ton segment in the Chevrolet Silverado and GMC Sierra 1500, and we couldn't be more excited. The last time a -ton Chevy or GMC came with a diesel engine, the veritable Detroit Diesel V-8 is the powerplant that was used. The 3.0L Duramax I-6 is a brand-new engine that combines the inherent smoothness and refinement of an inline-six with the torque and efficiency of a diesel. The Duramax produces 277 hp and 460 lb-ft of torque, with 430 lb-ft available right off idle at 1,250 rpm. The engine is paired with an excellent 10-speed automatic transmission. When we drove the Silverado diesel, the new gearbox's quick and very smooth upshifts and downshifts immediately impressed us. With the truck loaded—towing or void of any payload—the 10-speed's gearing is spaced (on the tight side) to help keep the engine in the sweet spot of its torque range.
Photo 13/52   |   012 Diesel Buyers Guide 2020 Chevrolet Silverado Diesel
Photo 14/52   |   The 3.0L Duramax diesel I-6 is a "clean sheet" design that delivers not only more power, but better efficiency than the 2.8L Duramax I-4 in the Colorado!
Towing capacity with the diesel is a maximum of 9,300 pounds, which is less than the comparably priced gasoline V-8 engines. The other side of the argument in favor of the diesel is the fact that the EPA-estimated 23/33 mpg city/highway (two-wheel drive) blows even the four-cylinder turbocharged gas engine out of the water. During our first drive, we saw an indicated 33-mpg average. Get this: The Silverado 1500's fuel economy figures are even better than the smaller Colorado diesel with its 2.8L I-4 diesel.
Photo 15/52   |   014 Diesel Buyers Guide 2020 Chevrolet Silverado Diesel
Photo 16/52   |   015 Diesel Buyers Guide 2020 Chevrolet Silverado Diesel Interior
The redesigned Silverado has an all-new interior and a heavily redesigned exterior, with styling that certainly stands out. For 2020, the Silverado adds the option of adaptive cruise control, something we missed when the truck debuted in 2019. Inside the Silverado, the styling is clean, and the trailer-brake controller is moved to the center stack, where it should have been all along. Like several other trucks this year, the Silverado is now available with 360-degree view cameras, a feature that's not new to the industry but certainly welcome in fullsize pickups. The truck also gains a few new tricks from the Heavy Duty lineup, with a camera package that offers 15 different views, including trailer-mounted cameras that stitch images together for an "invisible" trailer view, letting drivers see exactly what's behind the trailer when towing. Everything from hooking up a trailer to towing and backing is covered.
Pricing for a '20 Chevrolet Silverado 1500 diesel starts at $45,200.
Photo 17/52   |   The '20 Chevrolet Silverado 1500 borrows the same camera technology found in the HD trucks. They enable 15 unique views, including many that are helpful while towing, including an "invisible"-trailer presentation.
Chevrolet/GMC Silverado/Sierra 2500HD/3500HD
For 2020, Chevrolet and GMC also introduced all-new versions of their popular Silverado and Sierra HD pickups. Basically, the only thing that isn't changed is the 6.6L Duramax L5P V-8 turbodiesel engine. The powerplant still puts out 445 hp and 910 lb-ft of torque, but thanks to the addition of a fantastic new 10-speed automatic transmission and upgrades to the chassis and suspension, HD Silverados and Sierras can now tow an astonishing 35,500 pounds when properly equipped. That's more than the Ram 3500 Heavy Duty, despite the Ram's higher torque figure. Though few will ever put that headline number to the test, the improvements make towing better across the board, no matter how much weight you're pulling.
Changes in technology include the addition of more camera angles. The truck features 360-degree views, in addition to cameras that can be mounted on the trailer, giving the driver a look at what's behind, or combining a few views to make the trailer "invisible" on a display screen. When Truck Trend drove a Silverado HD, Editor Jason Gonderman says he loved the view when merging onto the highway but notes it is canceled when a turn signal is activated. Perhaps the biggest change, and improvement, is the new 10-speed Allison automatic transmission. Truck Trend wrote, "One word: amazing. We went into our drive with high hopes for this new transmission, and we were immediately impressed." There's no more hunting for gears, like in a six-speed-equipped truck, and 100 percent of the torque is available in First gear, meaning better acceleration from a stop, which is most noticeable when towing.
Photo 21/52   |   020 Diesel Buyers Guide 2020 Chevrolet Silverado 2500hd Highcountry
Photo 22/52   |   Though the HD Chevy Silverado and GMC Sierra lack some of the automated driver aids of the competition, for 2020, General Motors packed in usable features that make towing even easier for novices and seasoned drivers alike.
When deciding which truck to get, Chevy and GMC have the notable distinction of offering 30,000-plus pounds of towing capacity in all its 3500 dualie trucks, from the regular cab to the crew cab High Country and Denali. While certainly usable, don't get us wrong, the interior on Chevy's all-new truck feels dated when put up against the Ram and Ford competition. Step over to the GMC side, and you have the Denali and AT4 models, which offer a different take on their Chevrolet counterparts. The Denali is an incredibly capable downright luxurious pickup, while the AT4 bridges the gap between mild off-road trim and something dedicated like the Ram Power Wagon, except with a diesel engine option.

Prices for '20 Silverado 2500HD diesel models start at $48,260, and 3500HDs at $49,660. Pricing for the top-of-the-line 3500HD with the 35,500-pound tow rating had not been confirmed by our deadline, but a '19 model with dual rear wheels starts at $51,790.
Photo 25/52   |   The 2020 Chevrolet Silverado 3500 takes the crown for big-ticket towing, with an astonishing 35,500 pounds of fifth-wheel capacity.
Photo 26/52   |   Software stitches together the images of several cameras mounted throughout the Silverado and Sierra HD, including one installed on the trailer, to create an "invisible"-trailer effect that can be displayed on the center infotainment screen.
Photo 27/52   |   Want an off-road trim that does more than just add lockers and tires? Well, the Sierra AT4 is worth a look then.
Photo 28/52   |   If you want to tow in absolute luxury and bring everything with you, the '20 GMC Sierra HD Denali should be on your short list.
Chevrolet/GMC Express/Savana
Chevrolet Express and GMC Savana fullsize vans continue to soldier on unchanged for 2020. The two are body-on-frame fullsize vans, while most of the segment has moved to unibody construction. The vans represent a known value for companies looking for function and value. Though, when considering cost, it's worth noting the Express starts just $1,000 less than a Ford Transit with a diesel, making the entry-level price hard to justify on its own. Depending on the application, the only advantage the Express and Savana hold over their competitors is a more entrenched (and thus cheaper) upfit market, for businesses that need a custom solution for their vans. Both models can be equipped with the same 181hp, 369-lb-ft-of-torque 2.8L Duramax I-4 engine that's paired with a six-speed automatic transmission and found in the Colorado/Canyon duo.
Pricing for the '20 Chevrolet Express cargo starts at $37,165 when equipped with the diesel, and $40,090 for the passenger van.

Mercedes-Benz/Freightliner

Sprinter
The '20 Mercedes-Benz Sprinter van is available in two main variants: Cargo and Passenger, with a Crew van splitting the difference between the two. Under the hood, the Benz van has just one turbodiesel engine option, a 3.0L V-6, which is paired with a seven-speed automatic transmission and rear- or all-wheel drive. The I-4 from last year is dropped. Though Ford introduced all-wheel drive on the Transit this year, only Mercedes makes the option available with its diesel engine as well. The V-6 produces 188 hp and 325 lb-ft of torque, giving the van a towing capacity of 7,500 pounds and a maximum payload of 6,735 pounds, when properly equipped.
Photo 32/52   |   Mercedes-Benz discontinued the four-cylinder engine option for 2020, likely on account of a low take rate. The 3.0L V-6 engine has power and reasonable efficiency, making the smaller, less powerful I-4 rather redundant.
Photo 33/52   |   032 Diesel Buyers Guide Mercedes Benz Sprinter
When the editors of Truck Trend, our sister magazine, sampled a '19 Sprinter with the turbodiesel engine, they liked the changes Mercedes made when it introduced the redesigned van. The Sprinter carries quite a bit of technology with it, including active safety features you would expect to find in Mercedes-Benz passenger cars rather than commercial vans often destined for airport-shuttle duty. Some of the features, like blind-spot alerts, rear cross-traffic warnings with automatic braking, and surround-view cameras with guide lines while reversing, make perfect sense for a big box-shaped van. Adaptive cruise control, lane-keep assistance, traffic-sign recognition (to keep track of changing speed limits), and a driver-attention monitoring system help keep drivers alert and safe. A thoughtfully designed telematics system allows fleet managers to remotely monitor fuel levels, maintenance, and mundane things, such as the doors being left unlocked.
Photo 34/52   |   Yeah, we'd ride in this airport shuttle.

Pricing for the '19 Mercedes-Benz Sprinter starts at $40,985 for a cargo van, with four-wheel drive being a $7,800 premium over rear-wheel-drive models.
 

Ram Trucks

Ram 1500 EcoDiesel
The redesigned Ram 1500 was introduced in 2019, and for 2020 it is available with an updated version of the 3.0L EcoDiesel V-6 engine. There's a lot to like, but one big difference over the previous truck stands out: the diesel is available in every model and configuration. Yes, that includes everything from the humble Tradesman work truck to the luxurious Limited—and even the Rebel off-road edition.
Photo 36/52   |   For the first time ever, the '20 Ram 1500 Rebel is available with a diesel engine. It's not the same as the Hemi, of course, but it's darn good in its own way.
The 3.0L turbodiesel V-6 is significantly worked over for the Ram 1500, with a laundry list of new or upgraded items in the cylinder head and fuel system, in addition to a new turbocharger. The result is 260 hp and 480 lb-ft of torque at 1,600 rpm, which is more torque that comes in sooner than it does in the previous engine. The towing capacity is increased as well, with a headline number of 12,560 pounds. Fuel economy figures weren't available by our guide's deadline, but Ram says it will be class-leading. It has to beat the Silverado 1500's 23/33 mpg city/highway to take the crown. Who would have thought we would see all three of the segment's most popular trucks get 30-plus mpg on the highway?
When Diesel Power drove the '20 Ram 1500 EcoDiesel, Editor KJ Jones found the available technology makes it more pleasant to live with on a day-to-day basis. The Rebel, which wasn't previously available with a diesel option, is very capable, from general trail running to rock climbing and hill-descent. With the diesel engine and the optional 33-gallon fuel tank, 800 miles of range between fill-ups seems possible with our back-of-the-napkin calculating.
Pricing for the '20 Ram 1500 with the EcoDiesel starts at $38,585, making the Ram the cheapest (by more than $6,000) way to get into a -ton diesel this year.
Photo 43/52   |   The third generation of the EcoDiesel V-6 engine has more power and more torque. By the time you read this, fuel-economy numbers will be out, too, and we expect they'll be even better than before.
Ram 2500/3500
Though four-digit torque numbers are nothing new for Diesel Power readers, Ram finally turned the volume up to 11 on its 3500 and gave it 1,000 lb-ft of torque. No ECM tuning, just turnkey from the showroom floor. The Heavy Duty Rams are now enjoying their status as King of the Torque Hill. Power for the highest-output 6.7L Cummins I-6 engine is up to 400 hp. When the redesigned Heavy Duty trucks were introduced in 2019, they offered a whole lot more than new grilles and more boost—the trucks are upgraded across the board.
Photo 44/52   |   With the aftermarket squeezing quadruple-digit torque numbers from the Cummins I-6L, it was only a matter of time until Ram did it—with a full complement of emissions equipment, too.
Exterior styling and interior comfort matches the class-leading 1500. It's much quieter than the previous truck. When Truck Trend drove the HD trucks last year the editors said, "The seats are comfortable, sound system incredible, and uConnect is one of the best infotainment systems available today. And with the amount of real leather, wood, and metal used in the higher trims, these work trucks are putting many luxury brands on notice." How about towing? While driving the most powerful Ram 3500, Diesel Power's KJ Jones raved about the high-output 6.7L's ability to get 35,100 pounds moving from a dead stop, up a steep hill, with relatively no effort whatsoever. This truck is capable.
Photo 45/52   |   One notable feature of the Heavy Duty Ram trucks is the availability of an automatic emergency-braking system that can apply the trailer brakes as well.
Changes for 2020 are minimal but include the expansion of technological options across more trims. Active safety features, such as lane-keep assist and adaptive steering, are now available on all trim levels, while features like adaptive cruise control, forward-collision warning, and automatic emergency braking can also be ordered. Notably, automatic emergency braking is also applicable with trailer brakes. Adding to the thoughtful trailer features is support for tire-pressure monitoring for up to 12 trailer tires and four trailer profiles.
Other changes for 2020 include a 50-gallon fuel tank on Crew Cab models with the 8-foot bed, and two new exterior-paint-color options: Olive Green and Hydro Blue.
Photo 46/52   |   The Ram trucks have what many people believe are the best interiors in the segment right now.
Pricing for the '19 Ram Heavy Duty pickups starts at $44,440 for a 2500 and $45,890 for a 3500 with the "lower"-output Cummins, and $48,585 for the 3500 with 1,000 lb-ft of torque.
Photo 47/52   |   A gooseneck hitch, which uses a traditional tow ball instead of the fifth-wheel system (also used on tractor trailer trucks), might be a better option for people who want to tow heavy trailers but want to use the bed of their truck without removing a bunch of hardware.

Comings and Goings in the Diesel Segment
With so many diesel engines and truck models coming and going, it's hard to keep track sometimes. For 2020, there are exactly zero new passenger cars available with a diesel, and the trend of rigs coming and going hit the truck market as well. First off, the Ford Transit Connect diesel ended up being a non-starter. The small van was slated to get a 1.5L turbodiesel I-4 engine, which we thought would be a boon for businesses operating in urban environments. Then Nissan announced it was dropping the Cummins 5.5L turbodiesel V-8 option for the Titan XD. With competition heating up in the -ton segment, and with the Ram 1500 EcoDiesel reaching deep into the "tweener" capability category in which Nissan had positioned the Titan, it seems they decided to bow out.
With the reintroduction of the EcoDiesel V-6 at Ram, we're hopeful the automaker will bring back a few old faces to go with the two new ones introduced this year (Jeep Wrangler and Gladiator diesel): the Jeep Grand Cherokee and possibly a Ram ProMaster with the same third-generation EcoDiesel. Though we'd hesitate to call it a prediction, the introduction of a new four-cylinder EcoBlue diesel from Ford—one that also powers a Ranger overseas—points to the possibility of another diesel-powered entrant in the light-duty-pickup segment.
