Yes—Ford once installed Cummins engines in its medium-duty trucks (F-650/F-750) built in Mexico from 1998–2015 under a joint venture with Navistar, but Ford has never put a Cummins in its F-Series pickup line.
When did Ford stop using Cummins?
Ford ended its use of Cummins engines in 2016 when it switched the F-650 and F-750 to its own 6.7L V8 diesel.
That year marked a big shift—Ford pulled the plug on the Cummins ISB 6.7 that had been under the hoods since 1998. They brought everything in-house, wanting tighter control over engineering and warranties. Honestly, this move made a lot of sense for a company trying to streamline its operations.
Did Ford ever use Cummins engines?
Yes—Ford installed Cummins 6.7L inline-six turbodiesels in the F-650 and F-750 medium-duty chassis from 1998 through 2015 under a partnership with Navistar in Escobedo, Mexico.
These trucks rolled off the line as Ford badged vehicles, complete with Cummins ISB 6.7 engines mated to Ford’s own transmissions and chassis. Meanwhile, Ford’s consumer pickups—F-150, Super Duty, and Ranger—never got the Cummins treatment during those years.
Has Ford used Cummins Motors?
Yes—Ford used Cummins inline-six diesel engines exclusively in its F-650/F-750 medium-duty trucks between 1998 and 2015 as part of a joint venture.
The engines came straight from the Escobedo plant, then got paired with Ford’s driveline bits. Ford’s consumer trucks and vans? No Cummins there—just Ford’s own powerplants.
Can you get a Ford with a Cummins?
No—since 2016, Ford no longer offers any model with a Cummins engine installed from the factory in any retail, fleet, or medium-duty lineup.
Looking for a Cummins in a Ford? You’d have to go the aftermarket route—engine swaps or retrofits. Just be ready for some serious engineering legwork and compliance headaches.
Why did Nissan get rid of Cummins?
Nissan discontinued the Cummins 5.0L V-8 in 2020 after just four model years because it failed to achieve meaningful sales volume in the Titan XD segment.
Turns out, fewer than 10% of Titan XD buyers went for the diesel option. The extra $6,000–$7,000 price tag just didn’t make sense for most folks, especially when the fuel savings weren’t all that impressive.
Who currently owns Cummins?
Cummins remains an independent, publicly traded company (NYSE: CMI) as of 2026; its founders were Clessie L. Cummins and J. Irwin Miller.
Caterpillar doesn’t call the shots anymore, though the two companies still team up on engine tech. Cummins has been flying solo since the late ‘90s, and it’s doing just fine.
Is Cummins or Duramax better?
The current Duramax 6.6L L5P produces 445 hp and 910 lb-ft, beating the latest Cummins 6.7L Ram’s 420 hp and 1,075 lb-ft in peak ratings.
Duramax wins on pure horsepower, but Cummins flexes its muscles with way more torque down low. Real-world towing? Depends on the truck, load, and where you’re driving.
Does Caterpillar own Cummins?
No—Cummins is an independent, publicly traded company as of 2026 and has not been owned by Caterpillar since the late 1990s.
Caterpillar used to hold a big stake and even had a seat on the board, but Cummins clawed back its independence decades ago. They’ve been going it alone ever since.
What is the best diesel engine ever made?
The Cummins B-Series inline-six (circa 1984–present) is widely regarded as the most influential and durable diesel engine ever built for light- and medium-duty trucks.
This thing is a legend—a simple pushrod design that’s still chugging along after a million miles. Other heavy hitters? The GM 6.6L Duramax, the International 7.3L Power Stroke, and the monstrous Wärtsilä-Sulzer RTA96-C two-stroke marine beast.
What is the best Cummins engine?
The current 6.7L Cummins Turbo Diesel (ISB 6.7) is the most powerful and capable Cummins offered in a consumer pickup, delivering up to 420 hp and 1,075 lb-ft in the 2026 RAM 2500/3500.
It’s basically the B-Series architecture on steroids, with modern fuel injection and emissions tech. If you’re towing or hauling heavy loads, this engine doesn’t mess around.
Why was the 7.3 Powerstroke discontinued?
The 7.3L Power Stroke was discontinued after the 2002 model year because it could not meet tightening California noise regulations, not due to emissions standards.
Ford swapped it out for the 6.0L Power Stroke in 2003, which kept the torque but dialed down the racket. Noise rules got stricter, and the 7.3 just couldn’t keep up.
What makes Cummins engines so good?
Cummins engines excel due to their robust inline-six architecture, conservative power tuning for longevity, and legendary low-end torque that simplifies towing and hauling.
Their simple valvetrain and forged internals mean these things can run forever in the right hands. We’re talking million-mile service lives in vocational work—no wonder they’re so respected.
Is Nissan discontinuing the Cummins?
Yes—the Nissan Titan XD with the Cummins 5.0L V-8 turbodiesel was discontinued after the 2020 model year and is not available in any 2021–2026 model year.
Nissan pulled the plug on diesel Titans entirely, focusing instead on gas-powered turbo setups. The Cummins experiment lasted just a few years before they decided to move on.
Did Nissan discontinue the Cummins?
Yes—the Nissan Titan XD Cummins turbodiesel (5.0L V-8) was discontinued after the 2020 model year and has not returned as of 2026.
It was a bold idea—light-duty Cummins power in a full-size truck—but sales never took off. Nissan’s diesel chapter closed fast, and they haven’t looked back.
