The Tesla Cybertruck’s tough character can help address a horrible emissions trend
An emissions problem that seems worse than Dieselgate may be brewing in the United States, and it would likely take a perception shift to battle it well. As indicated by a new federal report from the Environmental Protection Agency’s Office of Civil Enforcement, over half a million owners and operators of diesel pickup trucks in the US have been illegally disabling their vehicles’ emissions control technology during the past decade. This trend, which continues to be popular, have allowed excess emissions equivalent to around 9 million extra trucks on the road.
Intentional Emissions
The EPA’s findings in its report echo the shocking revelations of the Dieselgate scandal, which involved Volkswagen admitting to illegally installing defeat devices in millions of passenger cars worldwide to cheat emissions tests. About half a million of these vehicles were sold in the United States. Yet inasmuch as Dieselgate was shocking, what makes the EPA’s recent report quite alarming is the fact that truck owners themselves are the ones–as well as small auto shops–who are willingly installing the illegal emissions-increasing devices on their pickups.
This makes it extremely difficult to accurately measure the scope of the US pickup truck market’s emissions problem. The EPA’s report estimates that there are over half a million pickup trucks in the US equipped with emissions-increasing devices over the past decade. However, the EPA’s study only focused on devices that were installed in heavy pickup trucks like the Chevy Silverado and the Dodge Ram 2500, which weigh between 8,500 to 14,000 pounds. Considering that some owners of smaller trucks like the Ford Ranger may also be engaged in the same practice, there is a good chance that the US’ pickup truck emissions problem may very well be far bigger, involving millions of vehicles nationwide.
“One reason it is difficult to estimate the full extent of tampering nationwide is that the Air Enforcement Division has reason to believe this conduct occurs within most or all categories of vehicles and engines, including commercial trucks, passenger vehicles, pickup trucks, motorcycles, forestry equipment, and agricultural equipment,” the report read.
Worse than Dieselgate
According to the report, the modifications that “diesel tuners” in the US place in pickup trucks could result in the release of over 570,000 tons of nitrogen dioxide, a substance associated with diseases like heart and lung disease, over the lifetime of the vehicles. This is more than 10x the excess nitrogen oxide emissions attributed to Volkswagen’s Dieselgate vehicles that were sold in the United States. The report further stated that the modified pickup trucks will hit 5,000 excess tons of industrial soot over their lifetime. Industrial soot, also known as particulate matter, is linked to respiratory diseases and higher death rates for COVID-19 patients.
John Walke, an expert in air pollution law at the Natural Resources Defense Council, noted in a statement to The New York Times that the EPA’s findings came at the worst time possible. “A global respiratory pandemic is the worst time to find out that there is this massive cheating by the makers of these devices. That is an astronomically high level of smog-forming pollution. It’s happening at ground level where people are breathing the fumes. And if the problem extends to other vehicles it’s almost unimaginable what the health impact will be,” he said.
Phillip Brooks, a former EPA emissions investigator and a veteran of the Dieselgate case, shared his thoughts on the US pickup truck market’s budding emissions controversy. “The aftermarket defeat device problem is huge. A lot of people just don’t understand what the problem is — your average person buys a vehicle and says, it’s my vehicle, I can do what I want with it. They may not even be aware that these devices are illegal,” he said. “But the real question is impact. If 10 people do it, there’s no impact. But these are numbers that are meaningful for air quality. This is not a great way to express how to be a free American, but there are a lot of people out there who think that way.”
The Need for a Diesel Pickup Predator
To battle such a horrible emissions trend, a change of perception is needed that is not that different from what the Model S ushered in for the high-performance sedan market. Diesel tuners, after all, equip vehicles with illegal emissions-increasing equipment largely to improve a pickup truck’s performance. If a vehicle were to be introduced in the pickup truck market that is so far ahead in durability, power, and performance compared to the veterans of the pickup segment, then large diesels could end up going the way of horse-drawn buggies. There are few vehicles that are better at leading this charge than the Tesla Cybertruck.
Similar to the next-generation Roadster, the Tesla Cybertruck has the potential to be a “smackdown” of sorts to the diesel pickup truck market. It’s a large vehicle with a domineering stance designed to look like a futuristic armored personnel carrier. Avid diesel aficionados tend to poke fun at EVs due to their tame, sleek, looks. There’s nothing of that in the all-electric pickup. The Cybertruck, with its XY, origami-like exoskeleton, is a steel beast: tough, unapologetic, and it looks like something that even a large diesel truck should not cross. This trend continues to the Cybertruck’s performance and utility, with its 0-60 mph time of 2.9 seconds, its 6.5-foot truck bed, its 14,000-lb towing capacity, and 500+ miles of range.
Assuming that Tesla does release the Cybertruck with specs that meet those that were announced during the vehicle’s unveiling, the all-electric pickup could utterly outperform diesel rivals to such a degree that it would be embarrassing for traditional trucks to stand toe-to-toe against the steel monster. And once this is established, perhaps the time would soon come when diesel-powered modified trucks could become laughable in the face of superior vehicles that just happen to have zero emissions. Such a time, while unfortunate for the US’ long history of large diesel trucks, would likely be appreciated by the environment and the populace as a whole.

A Tesla Semi caught fire in Hayward, California, which caused both directions of traffic to shut down for hours before being completely reopened early on Wednesday, the California Highway Patrol said.
The fire occurred just after 5:30 local time in Hayward on Tuesday, as the Semi caught fire in the southbound lanes of I-880 before CHP officials made the decision to shut down both lanes of traffic due to potential risks from hazardous chemical smoke.
There were no injuries reported.
🚨 A Tesla Semi reportedly caught fire, with California Highway Patrol confirming. The Semi was on I-880 SB
An estimated 5,000 to 7,000 semi-truck and large commercial vehicle fires occur on U.S. roadways every year

The cause of the fire is currently unknown, as neither Tesla nor the CHP have not determined a cause.
However, some images taken before the Semi was completely destroyed by the fire seem to indicate this might have been an older unit, as it appears to be one of the designs that Tesla shipped as part of its pilot program, before revising it and starting mass production just a month ago.
@Tslachan From on of the videos looks like it’s an old Semi (not the refresh version that recently started production) https://t.co/KzwmR2kXow

At the time of publication, CHP had not returned our request for a comment for additional details, including the Semi involved and any potential collaboration on an investigation between the CHP and Tesla. We will update this story when we hear back from them.
The southbound lanes were reopened at 3:30 a.m. on Wednesday, with the northbound lanes opening last night a few hours after the fire began. The CHP did state that the lithium batteries were “incredibly difficult to extinguish,” according to NBC Bay Area.
The truck’s driver said that the Semi caught fire, but he did not have an explanation.

Tesla’s launch of the “Emergency Drive Away” function a few months back offered owners a safe option to evacuate an area if they were in reasonable danger. The function finally got its first use in the real world, but it appears it was by mistake.
A video shared by u/Joshalander in the r/TeslaLounge subreddit recorded the instance from his vehicle and said the incident took place in Austin this past weekend during the city’s F1 Race.
“Was charging around 6 AM this past Sunday in Austin before heading to the F1 race and heard a pop. Looked over and saw the new emergency drive-away feature in action. Genuinely felt bad for the dude when he got out and realized what happened, since he looked exhausted and only seemed to half-read the prompts.”
🚨 Here’s the first look at Tesla’s Emergency Drive Away function in action:
Apparently this driver accidentally enabled it and drove forward; you can see the Supercharger pull with the car.
Tesla said previously this would cost up to $25k if not used properly. https://t.co/B4qQRrsO6B

Emergency Drive Away unlatches the Supercharger connector from the vehicle, but still causes damage to both the car and the Supercharger. Tesla has said that it will cost up to $25,000 in repairs to have everything fixed back to normal.
Additionally, the company said that if it were not used in an emergency situation, the driver of the vehicle who activated the Emergency Drive Away feature would be responsible for all repair costs.
Tesla constitutes the following situations as reasonable justifications for activating the feature:
- You face an immediate threat to your life or personal safety.
- You must leave the area immediately.
- Exiting the vehicle is unsafe.
- Unplugging the charge connector would unreasonably delay your departure or expose you to a risk to your personal safety.
After using the feature, Tesla requires the driver to schedule Service so the car can be inspected.

Tesla’s Cybercab battery design could make robotaxis even cheaper
Tesla built the Cybercab’s battery pack with spare room for a future switch to LFP.
Tesla built the Cybercab’s battery pack with empty space inside it on purpose, and the reason points to a cheaper robotaxi down the road.
Robert Sumpf, Tesla’s director of mechanical design engineering for battery modules and packs, said the extra room beside and beneath the Cybercab’s modules was left there so the company can move to lithium iron phosphate cells later. “So, we protected this pack to go to an even lower energy dense chemistry as we scale and need to bring LFP into the platform,” Sumpf said in a Cybercab deep dive with Munro Live.
The Cybercab runs on Tesla’s own 4680 cells with a nickel chemistry today. LFP cells store less energy for their size, so a straight swap would cut range. The reserved space lets Tesla add more LFP cells to make up the difference. In return, Tesla would get cells that cost less, run cooler and survive more charge cycles. LFP became the most used EV battery chemistry in the world last year.
Not all of that room was planned for a chemistry change. Lars Moravy, Tesla’s Vice President of Vehicle Engineering, said part of it exists because “we didn’t need as many batteries as we thought we did.” Tesla told Sandy Munro in early 2025 that it was targeting a Cybercab pack under 50 kWh with close to 300 miles of range.
The pack also breaks from the structural design Tesla used in some Model Y and Cybertruck builds. Instead of potting hundreds of cells into one block, the Cybercab uses four separate, individually sealed modules, so a bad module can be replaced without scrapping the whole pack. Sumpf was blunt about the older approach, giving the Model Y structural battery “a grade D” because it was hard to build and nearly impossible to repair. He estimated a fully structural pack gains about 10% more cell volume, but said “the issue is the service cost.”
That cost matters more for a car that rarely sits parked. Cybercab chief engineer Eric Earley said replacing an entire pack “before half a million miles is a killer on cost,” which is why remanufacturing and serviceability were built into the design from the start.
The same Munro Live tour produced Moravy’s admission that the Cybercab line at Giga Texas is now outpacing Robotaxi deployments, along with a look at the robotaxi’s unorthodox paint process. Tesla is aiming to deliver the first Cybercabs to outside customers by the end of 2026, though Elon Musk has said the vast majority will stay owned by Tesla and run as a transport service.
Sumpf did not give a date for an LFP version, name a cell supplier or say how a chemistry change would affect range. For now, the 4680 cars keep piling up: Texas DMV records from Tuesday list 544 Cybercabs authorized for Tesla’s Robotaxi fleet, more than the 507 Model Ys on the same roster for the first time.
