EPA 2027 and Past: How Will New Low-NOx Guidelines Have an effect on Fleets? – Gasoline Smarts
Regulators have set aggressive discount targets for NOx, a byproduct of high-temperature combustion of fossil fuels. NOx is chargeable for the brown haze usually seen over massive cities, particularly through the summer season.

The trucking business is approaching a fork within the highway. Inside the subsequent 12 to 18 months, fleets seeking to place orders for brand spanking new vans or fleet renewals must determine whether or not to take a look at some type of propulsion apart from diesel or take an opportunity on diesel vans geared up with new emissions-reduction applied sciences.
New NOx (Nitrogen Oxides) discount mandates from the Environmental Safety Company, printed late final 12 months, kick in successfully in 2026 with the model-year 2027 heavy-duty vans. With order boards at truck makers at present near full and a wholesome backlog of unfulfilled orders, lead occasions are getting shut to 2 years in some circumstances.
Fleets that plan to order vans in 2024 might face the prospect of getting a model-year 2027 truck geared up with new NOx-fighting {hardware}, together with cylinder deactivation, close-coupled multi-stream twin aftertreatment programs (two selective catalytic discount converters), and presumably heated diesel exhaust fluid (DEF) dosers.
We aren’t dismissing these and different applied sciences that provide a pathway to lowering NOx emissions by greater than 80%. The OEMs imagine they’re good options. The issue is, they’re operating out of time for enough sturdiness and reliability testing. These programs are complicated, they usually should be warranted for durations as much as 435,000 miles — practically 4 occasions longer than present EPA-imposed guarantee necessities.
That’s a fairly tall order for the OEMs. And it’s asking loads of fleets that bear in mind solely too properly the issues we bumped into in 2007 once we added diesel particulate filters to engines and cranked up exhaust gasoline recirculation charges. The brief growth and testing occasions for the know-how imposed on the time value the business billions in repairs and downtime.
Truck and engine makers have expressed deep considerations in regards to the growth timelines for MY 2027-compliant engines.

“I believe the 2007 and 2010 transitions are instructive,” says Patrick Sofa, senior vp of technical providers and accomplice at clear transportation and power consultants GNA (Gladstein, Neandross & Associates). “These first-generation engines with SCR had loads of issues. It took the engine producers a few years to kind them out. That value the engine OEMs, however it additionally value the fleets who couldn’t depend on the brand new autos they had been buying.”
Upkeep guide Bruce Stockton of Stockton Options remembers that interval properly, and he doesn’t wish to see a repeat efficiency.
“I’ve reviewed the brand new emission laws, and whereas not stunned at EPA’s aggressive strategy, I believe the laws themselves and the corresponding timeline for implementation are unrealistic,” he says. “I don’t suppose they supply sufficient lab and/or field-testing time to show the brand new know-how.”
Price and Complexity of Decreasing Truck Emissions
There’s very broad settlement that these new guidelines are going to be pricey and tough to adjust to, beginning with the {hardware} required to make the 82.5% step down in NOx emissions from 2 milligrams to .035 mg.
Feedback submitted when EPA first proposed this rule final 12 months had references to value will increase from $25,000 to as a lot as $35,000. Thorough evaluation of the ultimate rule, nonetheless, has analysts agreeing the upfronts might be considerably much less.
“Newer considering — as a result of the EPA has pared issues again [from the proposed rule] — has everybody settling extra within the $20,000 to $25,000 vary on the nationwide degree,” says Tim Denoyer, vp and senior analyst at ACT Analysis.
Denoyer says about $5,000 might be direct gear prices, similar to the extra SCR system and the cylinder deactivation {hardware}. There are additionally some re-engineering prices. He warns that the most important piece of the fee enhance will come from the elevated helpful life and guarantee provisions within the laws.
The push to place compliant engines on the road in 2007 left the business with a legacy of failed elements and downtime from which some fleets by no means recovered.

“Having a protracted guarantee on the emission system might be a profit for the purchasers, however that is going to enter the upfront value of the truck,” he explains.
Denoyer additionally believes the dual-dosing SCR perform will imply shopping for extra diesel exhaust fluid.
“DEF consumption goes to go up, in all probability fairly a bit, however roughly double,” he says.
How Will the Trucking Business Realistically Attain EPA NOx Discount Mandates?
We don’t but know the precise path ahead, because the OEMs haven’t but opened up about their methods. However the main contenders are cylinder deactivation and dual-dosing SCR programs.
Cylinder deactivation is used to assist keep increased temperatures throughout the aftertreatment system, which improves its NOx conversion effectivity. Twin-dosing SCR programs primarily deal with the emissions twice, as soon as on the way in which into the SCR and once more on the way in which out.
In numerous feedback to final 12 months’s proposed rule, references had been made concerning the necessity to maintain the SCR system as shut as potential to the engine to attenuate thermal losses by way of the exhaust tube operating from the turbocharger to the inlet of the aftertreatment system.
Earlier much less stringent emissions requirements left some producers unable to ship compliant engines, forcing their withdrawal from the market.

This, in accordance with some commenters, might require some re-engineering of the engine bay. It additionally might be a pinch level for sure chassis configurations the place house doesn’t at present exist for such programs.
There have been additionally references within the feedback to the problem of creating this work with quite a few scores inside an engine household.
EPA, nonetheless, did scale the ultimate rule again a bit from its authentic proposal, which might provide engine makers just a little extra latitude.
“There have been a number of technical modifications to the ultimate rule from the unique proposal that make for a really robust commonplace, however one which — talking strictly for DTNA — we imagine is achievable throughout numerous chassis configurations,” says Sean Waters, DTNA’s VP of compliance and regulatory affairs. “We’ve intensive expertise assembly earlier requirements and a larger understanding of the know-how that can permit us to satisfy these robust, enforceable requirements for NOx discount.”
Navistar officers additionally acknowledged the brand new guidelines are complicated, however that it’s assured its new S13 Built-in Powertrain might be as much as the problem.
“Any new regulation will problem the most effective producer to develop a cheap and sturdy product for his or her prospects,” says Jacqueline Gelb, Navistar’s VP of presidency relations. “We work cooperatively with all our stakeholders to develop merchandise that not solely meet the usual, but additionally exceed buyer expectations for efficiency, reliability and security.”
Analysts say measures to double-dose the SCR will double fleets’ DEF consumption.

If the OEMs appear assured of their skill to satisfy the rule, sentiment within the trenches seems a bit completely different.
Stockton says he has performed some evaluation on the ultimate rule and has conferred together with his suppliers on the problem. He doesn’t sound fairly so assured.
“I’m unsure that is achievable with out utilizing some sort of a hybrid resolution, presumably diesel-electric or diesel-hydrogen,” he says. “The OEMs I’ve spoken with inform me they do not but know which applied sciences or mixture of applied sciences might be required to satisfy the brand new laws. My sources inform me that there’s no technique to meet the brand new laws utilizing diesel-powered engines alone.”
Hybrid know-how isn’t out of the query at this level, however emissions credit might additionally present engine makers with the respiration room they should obtain the 0.35 mg commonplace by 2027.
That leaves one questioning if compliance is even potential with divine intervention.
Banking Emissions Credit
GNA’s Sofa thinks emissions credit might be key to compliance.
“I believe you’re right that a lot of the engine producers don’t imagine that diesel engines can meet what we name the direct commonplace in 2027,” he says. “The direct commonplace is the 35 mg commonplace you would need to adjust to with out credit. However EPA has constructed into this rule the flexibility to generate credit for NOx, which can be utilized to certify engines above the direct commonplace from 2027 by way of 2034.”
Within the close to time period, he expects various diesel engine producers will start certifying their engines beneath the present 200 mg commonplace however not as clear because the 0.035 mg direct commonplace by 2027. That, he says, will allow them to financial institution a sure variety of credit over the subsequent few years.
“They might additionally make use of a couple of different mechanisms to generate credit,” he says. “That can permit them to not all of a sudden should cease promoting diesel engines in 2027, but additionally be capable to lengthen the gross sales lifetime of these engines and hopefully present sufficient time for the market to get to the purpose the place we are literally capable of bridge the hole and transition to zero-emission or another considerably cleaner combustion options.”
Diesel Alternate options Are Scarce
Considerably cleaner options, at this level, are few and much between.
EPA’s low-NOx regulation is meant to push diesel fleets towards electrification, however at this early stage of that push, electrification isn’t a viable possibility for many fleets. Vary stays a problem, however the greatest stumbling block, presently, is the charging infrastructure.
“Overwhelmingly, infrastructure is slowing us down by way of EV deployment,” DTNA President and CEO John O’Leary mentioned. “Website prep, allowing, and building delays all contribute to deployment occasions being measured in years, not weeks or months.”
Talking to a gaggle of trucking journalists in Las Vegas forward of the revealing of the corporate’s SuperTruck II undertaking, O’Leary mentioned prospects are having to shelve enlargement plans for his or her BEV fleets due to the shortage of charging infrastructure.
“There’s loads of will within the regulatory and political arenas to make that occur, however whenever you begin speaking about shifting giant megawatt strains of electrical energy round and constructing new substations, it simply takes time,” he mentioned.
So, if electrification isn’t a sensible possibility proper now, what’s? Hydrogen faces at the least as lengthy an uptake interval as battery-electric, doubtless longer.
Which leaves pure gasoline.
“I believe pure gasoline proper now could be type of the incumbent different,” says GNA’s Sofa, noting that engines for Class 7 and eight in long-haul, vocational and transit functions are already licensed at or beneath the 2027 commonplace.
“They appear to be the pure go-to engine, and we may very well see engine producers selling the sale of the low-NOx pure gasoline engines within the close to time period as a technique to not solely put together fleets for pending transition, but additionally to construct a credit score financial institution in order that they’ve choices post-2027,” he says.”
Sofa can also be watching Hyliion’s Hypertruck ERX pure gas-powered range-extender electrical truck.
“That’s an attention-grabbing platform and, relying on the way it will get licensed the below the rule, it might additionally generate substantial further credit [for the OEM],” he says.
Pure gasoline is probably not a preferred different in the intervening time, however impressions might change when Cummins brings its X15N 15-liter pure gasoline engine to market in 2024.
Puneet Jhawar, the overall supervisor of Cummins’ world pure gasoline enterprise, informed HDT final summer season that curiosity within the new 15L engine from current prospects — in addition to those that had by no means thought-about pure gasoline — surged following the announcement of the brand new engine.
Is a Truck PreBuy on the Horizon?
The 800-pound gorilla on this dialogue, after all, is fleets’ worry of the unknown, coupled with the reminiscence of what occurred in 2006-2007. Stockton believes meaning a serious pre-buy.
“Along with a pre-buy over the subsequent 36 months, it’s additionally inevitable that we’ll see a ‘no-buy’ beginning in January 2026,” he asserts. “The upside to that’s spare components will now not be briefly provide. The OEMs and components suppliers might be in over-supply mode with truck manufacturing down considerably.”
Certainly, the obstacles to a easy transition are piling up. EPA’s 2027 low-NOx mandate might be difficult sufficient, however the California Air Assets Board might add an extra NOx discount requirement in 2024.
“The nationwide pre-buy that we’re anticipating is admittedly prone to decide up mid-year 2025 and undergo 2026, forward of the 2027 requirements,” says ACT’s Denoyer. “On prime of that, California is planning on going forward with its low-NOX laws for 2024. There are nonetheless some query marks within the business about if and the way that is going to occur. If it does, I believe there might be some pre-buying in California this 12 months.”
Based on GNA’s Sofa, the CARB rule is extra stringent than the EPA rule. It has a 0.02 gram (2 mg) commonplace in 2027, whereas the EPA rule is 0.035 mg.
“CARB additionally has an interim milestone, they usually have some further helpful life necessities within the heavy-duty engine group,” he says. “So, sure, there are some important variations between the 2 guidelines.”
Sofa provides: “The CARB rule would permit for producers to realize a 50-state compliant engine by certifying their complete nationwide diesel engine fleet to a better commonplace than what’s known as for within the ’24 to ’26 model-year interval below the present rule.”
A major pre-buy is the very last thing the truck and engine makers need. Each Daimler and Navistar informed HDT they count on minimal disruption.
“The Clear Truck Plan was drafted in a fashion that ought to considerably cut back the magnitude of any regulatory pre-buy,” DTNA’s Waters says. “Nonetheless, it’s exhausting to have a definitive concept of the complete impacts till EPA proposes after which finalizes GHG Section 3.”
Navistar’s Gelb says the corporate is collaborating with sellers, prospects and suppliers early within the regulatory course of to make sure know-how options which might be being developed for the market align with prospects’ enterprise wants.
“Via this partnership, Navistar believes that any know-how launched might be market-accepted and decrease any pre-buy/no-buy in 2026,” she says.
We’ve barely talked about GHG Section 3, which might apply to model-year 2027 and later vans. It might require truck and engine makers to decrease GHG emissions by primarily enhancing gasoline effectivity. GHG reductions might be good for fleets in that they create down gasoline consumption, however they could fear that the price of reaching these enhancements will outweigh the gasoline financial savings.
Advance Planning: Commerce Cycles and Acquisition Plans
There are a couple of upsides to a nationwide pre-buy. It creates short-term over-capacity, which has a destabilizing impact on capability and charges. It forces producers to double up on manufacturing, which might result in declines within the high quality of the completed product. Submit-prebuy, producers are sometimes compelled to put off staff, and that has a ripple impact all the way in which alongside the availability chain.
“The most important concern I’ve for the trucking business is including loads of capability in a pre-buy is simply inherently dangerous for charges and hurts truckers’ profitability,” ACT’s Denoyer says. “However over the long run, from a five- or 10-year perspective, I believe the upper value base for the business, and the elevated complexity, goes to truly assist pricing energy for fleets and assist them to boost charges. And finally, I believe it’s going to be a constructive.”
He says now could be the time to start out desirous about commerce cycles and future acquisition plans. We all know from expertise how pricey prolonged commerce cycles might be. Do you deal gear now that’s due for commerce in 2025-2026, or dangle on to it and trip out the storm? Smaller fleets that rely totally on used vans could be the least affected by a pre-buy, however that can actually drive up the price of secondhand gear.
“We’re in a really generational transition time,” GNA’s Sofa says. “The transition to zero-emission goes to occur. It will be tough and messy. And it is not going to occur on the timelines that individuals would really like or undertaking.
“My message for fleets is to essentially take note of what is going on on right here. Attempt to dig into how your fleet would look below a zero-emission operation and begin utilizing this time to prepare for when it’s important to do what it’s important to do. Do not wait ‘til the final minute to attempt to comply.”
