EPA Considering Tougher Emission Rules for Big Trucks

General Motors Says Heavy Duty Electric Pickups Are Coming

General Motors has made another proclamation at CES 2022, this time providing a timeline for electric variants of its heavy-duty pickups. HD EVs are scheduled for 2035, which just happens to be the same time it has promised to have phased out gasoline engines. Presumably, that means the hardest working of GM’s work vehicles will also be the very last models to go all-electric.

“As previously announced, our plan is to have all new light-duty vehicles be electric by 2035,” GM CEO Mary Barra said during her keynote address. “And today, I’m pleased to announce that we’ll introduce all-electric heavy-duty vehicles on that same timetable.”

Heavy Duty Recall: Ram Rescinding 131,000 Pickups Over Fire Risk

Ram has been subjected to numerous investigations over the last few years, especially in regard to its heavy-duty diesel pickups. We can throw another item onto the list, as the manufacturer has opted to recall 131,177 HD trucks from the 2021 and 2022 model year.

While we recently covered an investigation launched by the National Highway Traffic Safety Administration (NHTSA) to assess whether reports citing that late-model HD pickups using the 6.7-liter Cummins turbo diesel had motive issues, the current recall appears unrelated. The former investigation is centered around slightly older trucks and a loss of motive power presumed to be the result of defective fuel pumps that could warrant a recall. This issue is a full-blown recall surrounding a potential fire risk originating from an issue with the solid-state heater intake grid relay.

NHTSA Investigating Ram's Diesel Pickups

The National Highway Traffic Safety Administration has opened an investigation into nearly 605,000 heavy-duty Ram trucks. A report from the regulator’s Office of Defects Investigation has tabulated 22 complaints from the 2019 and 2020 model years, all of which use 6.7-liter Cummins turbo diesel engines, spurring the NHTSA to launch a formal investigation. Complaints revolve around loss of motive power, with most incidents occurring above 25 mph and resulting in the “permanent disablement of the vehicle.”

While the public was not made aware of the investigation until Monday, the agency launched its probe last Thursday on October 14th. The goal will be to establish how widespread the presumed defect is, what exactly caused it, and any potential safety hazards relating to the issue. Some headway has already been made, however.

Ford Says Electric Super Duty Trucks Aren't Happening

While Ford’s F-150 is slated for electrification, Super Duty versions of the F-Series are not. On Monday, the automaker told industry analysts that HD EVs weren’t in the cards — adding that customers can still expect all-electric versions of the Mach-E “Mustang” and Transit van.

“Our goal is to build a profitable electric vehicle portfolio,” John Lawler, Ford chief financial officer, explained during the forum hosted by Dan Levy of Credit Suisse. “To do that, we need to leverage our strengths and the scale that we have. We’re being very strategic about the platforms that we choose.”

Diesel's Not Done Yet: Cummins Explores Cylinder Deactivation

Despite the switch to low-sulfur fuel and ever more stringent emissions regulations around the world, compression ignition technology still gets a bad rap, tarnishing the remaining crop of diesel engine offerings despite their fuel economy advantages.

In the world of heavy duty pickups and large commercial vehicles, it’s a case of diesel or what else? Electric motors powered by battery banks the size of a refrigerator warehouse? Gotta use what works.

Diesel engine maker Cummins sees plenty of life left in the technology, and believes better is possible. If gasoline engines can shut down cylinders at will to conserve fuel, why not oil burners?

2020 Ford Super Duty First Drive - Long May You Truck

It’ll not have escaped your notice that the pickup truck segment is a murderously competitive arena. In fact, if it were an actual arena, it would be much like the Roman Coliseum — or at least the upcoming 49er/Chiefs tilt in Miami — with bodies strewn across the playing field and the crowd roaring for more.

This helps explain why the Detroit Three are intent on beating each other over the head with towing and torque numbers that have climbed to dizzying heights. For 2020, Ford has unleashed a Super Duty pickup with available four-figure torque or a monster V8 the size of which hasn’t been produced by Motown in decades.

Fans of heavy duty trucks with grilles the size of Texas have a lot to celebrate this year. Ram dropped its new HD in Detroit and GM previewed its alarmingly styled Heavy Chevy late last year. All signs point to Ford unfurling a new Super Duty very soon, possibly at the Chicago show next month.

Last year was a bountiful season for truck fans, with two of the Detroit Three introducing new iterations of their half-ton pickups. The twelve months ahead promise an equal amount of abundance – except this time, OEMs are doling out treats from the Heavy Duty cupboard.

Back in September, your humble author opined on this website that he would “not be surprised if Ram is the first manufacturer to crest 1,000 lb-ft of torque in a consumer truck.” Color us unsurprised, then, as the new 2019 Ram Heavy Duty pickup will indeed be available with four-figure torque.

Question Of The Day: What The Truck Do You Want?

Yesterday I told a story about a colleague of mine who was lookin’ for love in all the large places. Because this is TTAC, the conversation in the comments quickly turned to the traction merits of various drivetrain systems. You crazy kids. I bet that when most of you think about Fast Times At Ridgemont High, your minds immediately go to the one scene where we get a good look at the voluptuous curves of … Judge Reinhold’s 1960 LeSabre.

We’ve had a lot of conversations about trucks lately, whether it’s a Nissan Frontier, a Toyota Tacoma, or a Honda Ridgeline. You could say that we’re in some kind of trucking phase, and that it might be a while before we get the truck out of here.

So, what the truck do you want?

Ford Super Duty Parts Issue Makes It 'Impossible to Build' Lost Units

Ford was supposed to start rolling out their 2017 Super Duty trucks much earlier than they eventually did. The holdup, attributed to a parts issue, is over, but Ford isn’t out of the woods yet.

Rodney Janes, UAW chair for the affected Louisville truck plant, told The Wall Street Journal it would be “impossible to build all the lost units” that were held up during this summer’s parts snafu.

Powell Crosley does not get enough recognition and is largely forgotten even in his hometown of Cincinnati although the Greater Cincinnati and Northern Kentucky Airport has 2 Crosley cars on display. Crosley revolutionized radios by making an affordable radio that the masses could afford similar to what Henry Ford did with the Model T. Both Crosley and Ford did not invent the radio and the car but they made them widespread by making them affordable. I did not know about the Icyball but I did know about Crosley refrigerators, airplanes, cars, and radios.
