Cummins, maker of the beastly 6.7-liter inline-six diesels found beneath the hoods of various Ram Heavy Duty pickups, claims it is looking into its emissions certification and compliance process.

In a statement released Monday, the decision to investigate the process came after “conversations” with the Environmental Protection Agency and California Air Resources Board. Specifically, the probe targets the revamped engines used in Ram’s 2019 HD line, not the 5.0-liter V8 found in the Nissan Titan XD. (Read More…)

Yet another special edition Ram pickup has landed for your trucking enjoyment. With the freshly renewed half-ton truck finally finding its way into showrooms, FCA is continuing to throw premium materials at its heavy-duty brother in an attempt to tide it over until an all-new machine bows for 2020.

Aimed squarely at wealthy cowboys who tow a lot of stuff, the 2018 Ram Heavy Duty Longhorn Ram Rodeo Edition (yes, the word “Ram” appears twice in its official title) is laden with leather, chrome, trailering gear, and badges the size of Texas belt buckles.

Healthy competition lowers the price of consumer goods, the economists tell us, but it also raises torque ratings. Nowhere is this more apparent than among the Detroit Three automakers, with Ford, General Motors and Fiat Chrysler Automobiles locking horns, crossing swords (keep it clean…), and firing arrows at each other in a heavy-duty pickup war that’s only heated up in recent years.

It comes down to stump-pulling, gravel-hauling, trailer-towing twist. In 2015, the Ram 3500’s 6.7-liter Cummins inline-six turbodiesel topped the Ford F-350 SuperDuty’s 6.7-liter turbodiesel V8 by 5 lb-ft of torque — 865 to Ford’s 860. This clearly couldn’t stand, so for 2017 Ford upgraded the Power Stroke’s torque rating to 925 lb-ft, kiboshing Ram’s 2016 attempt to stay ahead with a 900 lb-ft rating.

With 2017 came further aggressions. This year saw GM pulling ahead to second place with its 6.6-liter Duramax V8, now upgraded to 910 lb-ft, knocking Ram down to third place.

Well, FCA’s having none of it. Just a day after Ford’s unveiling of a newly powerful second-generation 2.7-liter EcoBoost V6 and 5.0-liter V8, Ram fires this salvo: a Cummins with more grunt than any other rival. (Read More…)

2017 Ram Power Wagon

Impassioned calls for Ram to drop the Cummins 6.7-liter inline-six diesel into the Power Wagon are not new, nor is Ram’s response. I recently spoke with Jeff Johnson, Ram’s brand manager for heavy duty trucks, who unequivocally stated, “Ram has no plans to offer the Power Wagon with a diesel.”

Johnson pointed to the increased weight of the 6.7-liter Cummins versus the 6.4-liter Hemi V8 presently under Power Wagon hoods, as well as the difficulty of engineering the front end to accommodate both the diesel’s cooling requirements and the truck’s standard 12,000-pound winch.

We accept the reality of these challenges. But could Ram overcome them?

Absolutely, though Ram’s engineers have determined the cost outweighs the benefits. Even setting my enthusiast hat aside, I am not confident that bypassing this opportunity altogether is the best choice for Ram. (Read More…)

It’s hard to hear the name Cummins and not immediately think of a Ram pickup struggling valiantly to pull a gnarled tree stump out of the unyielding earth. Certainly, the company’s diesel inline-six and V8 engines are to the truck world what Nike is to professional sports.

While Cummins’ fossil fuel-powered engines and power systems show no signs of becoming passé, a company ignores the future at its own peril. The green revolution is afoot, we’re told, and internal combustion power will one day occupy the niche currently inhabited by electric propulsion. With this in mind, Cummins has a plan. (Read More…)

Since Dodge started producing trucks way back in 1921, it has never held the crown of the best-selling pickup truck in America. Not once. Not even when Dodge was the top brand in America.

It seems from the get-go Dodge has played third-fiddle in Ford versus General Motors pickup truck wars. But being third child meant that Dodge often struggled to be recognized in the market when compared to its more famous competitors.

For enthusiasts, that has always been a good thing.

It meant Dodge always had to be different. Dodge always had to be innovative, or more enthusiastic, or just plain shout more than anyone else. The result of all that was Dodge brought us some very trick trucks along the way that were cutting-edge, that defined a market, or were just plain cool.

With that in mind, let’s take a look at 40 years of pre-Y2K Dodge truck highlights (even when they haven’t been so successful).

5.6-liter Endurance® V8 Gasoline Engine to Power Nissan TITAN a

Nissan announced Tuesday that its new Titan and Titan XD pickups will be powered by an all-new 5.6-liter V-8 that makes 390 horsepower and 401 pound-feet of torque. The new V-8 replaces the aging mill that produced 317 hp and 385 pound-feet of torque.

According to Nissan, the new V-8 — dubbed Endurance — will be built at the automaker’s Decherd, Tennessee powertrain assembly that produces all powertrains for vehicles assembled in the U.S.

(Apparently, Nissan’s announcement broke the automaker’s press site. The site went down shortly after the announcement.) (Read More…)

In Part One we looked at Clessie Cummins’ development of the first practical and reliable diesel truck engines and his earliest attempts to race diesels in the Indy 500. Though he had succeeded in developing the technology, he still hadn’t achieved the ultimate proof of concept that market success brings. (Read More…)

(Note to readers: This was the piece on Clessie Cummins that should have appeared first. Unfortunately, Part 2 of the series ran first and will be rerun later this afternoon — Aaron.)

clessie-cumminsDiesel engines have been in the news lately, and not for good things. The admission by Volkswagen that it has been using a software device to cheat on government emissions testing of at least some of its diesels may taint compression ignition, oil-fired engines in the passenger car market. The trucking industry, however, will continue to use diesels. That’s mostly because of a guy named Clessie Lyle Cummins.

If you’re an automobile or truck enthusiast you likely know his last name, but just as likely know nothing about him.

His accomplishments date to building a working steam engine for his family’s Indiana farm as an 11 year old in 1899, casting the engine parts from molten iron poured into hand-carved molds. As a teenager, he started to take odd jobs including fixing machinery, which led to a job at the maker of Marmon automobiles — Nordyke and Marmon. He was also member of the pit crew of Ray Harroun’s Marmon Wasp that was the winner of the very first Indianapolis 500 race in 1911, and offered suggestions that made the car faster. Cummin’s loved the Indy 500 and his engines would eventually run there, with some measure of success. (Read More…)

WardsAuto reports that the next generation 2016 Toyota Tundra pickup will receive the Cummins 5.0L V8 turbodiesel for 2016, the same engine that will be powering the next Nissan Titan pickup, due for 2015. While Toyota had been working on a diesel engine with Hino, Toyota’s heavy-truck division, the economic crash of 2008 shelved the plans. With new found interest in light diesels and the new Ram EcoDiesel leading the way with favorable reviews and excellent fuel economy, Toyota looks to jump quickly into the light diesel truck market.

2014 RAM 1500 Eco Diesel Exterior-005

There’s just something about a diesel pickup truck that makes grown men regress into Tonka-loving children. Even my Prius-driving environmentalist friends in Berkeley admit they secretly want a diesel pickup. The problem of course is that diesel pickups are expensive (the cheapest diesel Ram 2500 is $36,975 and it doesn’t have an automatic transmission, the cheapest oil-burning F-250 is $38,250) and, for the majority of us, the high payload and towing capacities are overkill. While economical in a specific sense, the large diesel trucks aren’t “fuel-efficient” either. Until now. Mark your calendars folks, The 2014 Ram 1500 Eco Diesel is the half-ton truck in America sporting a small diesel engine.
