EPA finalizes first clean trucks rule in 21 years, but it could be better
The EPA has finalized a long-awaited update to their truck emissions rules, the first update to US truck clean air standards since 2001, though environmental groups say the EPA could do better.
The new rule starts in model year 2027 and is up to 80% stronger than the current standard. It will reduce smog-forming Nitrogen Oxide (NOx) emissions from trucks by almost half by 2045.
NOx is one of the primary components of smog, and is emitted by the combustion of gasoline and diesel. Diesel engines tend to produce much more NOx than gasoline engines, so heavy diesel trucks have significant NOx impacts. About 16-18% of NOx emissions come from heavy duty trucks (though in some states it’s higher, like in California at 32%), despite them accounting for a smaller percentage of total road traffic.
So, regulating the relatively smaller amount of trucks can have outsized influence on overall NOx emissions.
The EPA claims this new regulation will result in several benefits by 2045:
- Up to 2,900 fewer premature deaths
- 6,700 fewer hospital admissions and emergency department visits
- 18,000 fewer cases of childhood asthma
- 3.1 million fewer cases of asthma symptoms and allergic rhinitis symptoms
- 78,000 fewer lost days of work
- 1.1 million fewer lost school days for children
- $29 billion in annual net benefits
The regulations will also “increase useful life of governed vehicles by 1.5–2.5 times, and will yield emissions warranties that are 2.8–4.5 times longer,” according to the EPA.
But not everyone is happy with the new rule. While it’s a big step forward for diesel truck emissions regulation, environmental groups had hoped the rule would focus more on zero-emissions trucks, rather than merely making cleaner versions of dirty diesels.
The Natural Resources Defense Council hailed the EPA for finally updating these rules after 20 years of inaction, but claimed that “these standards fall short, and the agency missed a critical opportunity to slash soot and smog and accelerate the shift to the cleanest vehicles” – by which it means fully-electric trucks. And the American Lung Association praised the rule, looking forward to the EPA’s plans to issue more rules on cleaner trucks starting next year.
On the other side, the Diesel Technology Forum, an industry group in favor of expanded diesel trucking, seemed quite happy with the new rule. They claim this will help accelerate the turnover of old diesel trucks to newer, more efficient models – and think that electric trucks are not the ideal solution for trucking.
Thankfully, this isn’t the end, as far as the EPA goes. The EPA plans to release further rules for greenhouse gas emissions in heavy duty vehicles starting spring of 2023, and these rules will also go into effect in 2027. Today’s rule change focused on NOx emissions, but CO2 is another important emission to regulate in order to fight climate change.
Transportation is the largest source of emissions in the US. Medium- and Heavy-duty trucks combined are responsible for 26% of US transportation CO2 emissions. Light-duty vehicles are responsible for more – 57%, a majority of transport emissions – but there are a lot more of them than there are of trucks.
The world is currently well-above pre-industrial CO2 levels. Any carbon-positive technology, such as diesel, can only make CO2 levels go up when they need to be going down. The first step towards getting back to ~350ppm CO2 from our current measure of 416ppm (and rising) is to move to zero-carbon technology in every sector, particularly the most-polluting ones like transportation. Putting more new diesel engines on the road just ensures that they will continue polluting for decades into the future, and which will eventually need to be replaced by zero-emission trucks anyway.
The EPA had planned to issue truck CO2 rules this year, but due to new incentives for zero-emission vehicles in the Inflation Reduction Act, they pushed back their decision until this coming spring. With up to $40,000 available for commercial zero-emission vehicles and several new electric trucks just recently coming to market, the EPA seems confident that it can issue stricter CO2 rules than previously planned.

With the launch of the first-ever Class 8 vocational EV in the North American market, PACCAR Kenworth is raising the battery-electric bar and underscoring just how far the market has come since the Tesla Semi made its debut nearly a decade ago.
When Tesla pulled the wraps off its all electric Semi truck all the way back in November of 2017, the rest of the industry was hardly thinking about BEVs. Nearly a decade later, the world is still waiting for the Semi to begin regular production, and PACCAR is launching its second generation of HDEVs with the debut of this, the all-new Kenworth T880E vocational truck.
“The Kenworth T880E marks a groundbreaking milestone in Kenworth’s history as we bring to market the first Class 8 battery-electric solution built for vocational applications,” explains Kevin Haygood, Kenworth assistant general manager for sales and marketing. “The T880E is engineered to meet the evolving needs of operators and vocational fleets while still providing the durability, reliability and customization our customers expect.”
The new electric K-whopper is motivated by PACCAR’s in-house ePowertrain platform, capable of putting up to 605 hp and 1,850 lb-ft of peak torque to work, while delivering the same levels of drivability and dependability fleets expect from a Kenworth – but power and torque are only part of the T880E’s work-ready résumé.
Open to work
In addition to a stout, Class 8 electric chassis fitted with heavy-duty Kenworth brakes and axles, the T880E’s central drive eMotor allows for significant wheelbase flexibility so fleet buyers can spec out exactly the machine they need to get the job done. The T880E was also designed to enable lift axle installations from trusted Kenworth upfitters for a vocational-friendly BEV integration.
Additionally, the T880E features a wide selection of factory-installed options that include both high- and low-voltage ePTO (electric Power Take Off) ports, mechanical ePTOs, and the same wide array of body configurations as the ICE version.
Speaking of the ICE version, the electric T880E also can also be had in the same set-back front axle and set-forward front axle configurations with the same multi-piece hood construction. Inside the cab, the latest in driver-focused technology includes the Kenworth SmartWheel and a new 15″ DriverConnect digital touchscreen. Dash and vocational features like RAM Mounts and factory-installed PTO switches are available. The T880E is also offered with Kenworth ADAS packages for customers interested in DigitalVision Mirrors, Bendix Fusion, and Lane Keeping Assist.
It’s so big, you guys
The T880E was on static display at last week’s ACT Expo in Anaheim, California. Check with your local Kenworth dealer for availability.

The tire-blistering SU7 Ultra has been the Xiaomi brand’s flagship super sedan since its launch, but a controversial software setting has limited the car to “just” 900 hp in regular driving – resulting in an outcry from owners who ponied up for the big boy numbers. With its latest software update, that missing 648 hp is back on tap!
The SU7 Ultra made waves throughout the performance car world when a bright yellow striped example lined up alongside a white quarter mile king, the 1,000+ hp Tesla Model S Plaid, and promptly smoked it.
That wasn’t all. A preproduction SU7 Ultra prototype lapped the legendary Nürburgring circuit in just 6 minutes and 46.874 seconds, firmly stamping the 1,500+ hp Xiaomi’s alphanumeric into the track’s record books with a time nearly fifteen seconds quicker than a Rimac Nevera or, on the ICE front, either a Corvette ZR1, Viper ACR, or Porsche 918 (take your pick).
It’s hardly any wonder, then, that the customers who signed up – in droves, too – were disappointed to learn that the SU7 they were allowed to buy had been neutered by the safety nannies to the tune of nearly 650 hp. (!)
We’re so back
The outrage from SU7 Ultra owners was immediate. And, facing mounting pressure online and on social media, Xiaomi ultimately decided to withdraw the performance-limiting features while acknowledging the need for more transparent communication about future software updates they messed up, saying in a statement, “we appreciate the passionate feedback from our community and will ensure better transparency moving forward.”
So, rich people can rocket themselves down the road in 9 second hypercars again and all is right with the world. A happy ending – but one that sort of illuminates a fresh set challenges for automakers peddling “software-defined vehicles” to a market that still thinks of their cars as very much hardware defined products.
That’s evidenced by the resistance to pay for features by subscription and complaints by more informed customers that “software locked” range and convenience features just subsidize the cost of more expensive trim levels and pad profits for manufacturers and suppliers.
The new reality is playing out in real time now, and the Jeff Bezos-backed $20,000 electric compact pickup from Slate Auto is going the other way entirely – time will tell whether more, or less tech is the answer.

Tesla (TSLA) has started offering reduced interest rates on the new Model Y in the US — this equates to a direct discount on the brand new vehicle that was supposed to spark Tesla’s demand back.
The automaker has announced “1.99% APR or $0 Due at Signing available for well-qualified buyers” on the new Model Y in the US for the first time:
This amounts to a direct discount worth a few thousand dollars. It is the first widely available discount on the new Model Y coming just weeks after the cheaper non-Launch Edition launched in the US.
It follows a $2,000 direct discount that Tesla offered to early Model Y owners last week.
These discounts and subsidized financing point to soft demand for the updated best-selling vehicle in the US. Tesla just delivered a disastrous first quarter, which it mostly blamed on the Model Y changeover, resulting in lower inventory.
However, industry watchers, including Electrek, noted many signs that the Model Y changeover was not the only issue. Tesla added significantly to its inventory in the first quarter, and the wait times for the new Model Y were extremely short.
Now, the discount weeks after launching the new Model Y confirm the soft demand in the US.
It’s not as bad as Europe and China, where Tesla has already been offering 0% financing on the new Model Y for weeks.
Electrek’s Take
I think it’s clear by now: the new Model Y is not coming to save Tesla.
Let’s be honest: It will still be a significant vehicle program by volume. It just won’t help Tesla return to growth this year.
The RWD Model Y is still coming and has a chance to help in the US. It is already available in China, and it’s not helping Tesla much there, but that’s in a hyper-competitive market, especially at lower prices where the RWD Model Y operates.
Tesla’s performance in Q2 in China will be interesting since it is basically back to its regular lineup for the whole quarter.
The US appears to have been Tesla’s least affected market, but Q3 will be the real test with the full lineup and no backlog of demand for new Model Y.
