Leasing Demand Rises as Fleets Confront 2027 NOx Rule

For fleet operators weighing equipment purchase or lease options, the Environmental Protection Agency’s 2027 NOx emissions rule is adding another layer of uncertainty to an already complex decision. Rising truck prices, unclear maintenance implications and a soft freight market are also forcing fleets to reassess the amount of long-term risk they are willing to carry on their balance sheets.

The EPA’s tighter emissions standards for heavy-duty engines produced starting on Jan. 1, 2027, will make leasing more attractive, said Dean Vicha, president of NationaLease.

But he added that broader economic conditions, not just the 2027 emissions rule, play an even larger role in how fleets approach capital decisions. Long-term issues such as the economy, rising truck costs and the ongoing technician shortage remain the biggest forces shaping buy-versus-lease choices, Vicha said.

“All those things together are making the leasing solution more attractive than the ownership solution,” he said.

Under the EPA rule finalized during the Biden administration, allowable NOx emissions would drop from 200 milligrams per horsepower hour to 35 during normal operation, with limits of 50 milligrams at low load and 10 grams at idle. The rule also would extend emissions-related warranties from five years or 100,000 miles to 10 years or 450,000 miles and increase the useful-life requirement to 11 years or 650,000 miles.

While these standards aim to reduce emissions, fleets and leasing providers say their greater concern is how the changes may translate into ownership risk, including higher upfront costs, added complexity and uncertainty about residual values in the secondary market.

The regulatory environment remains unsettled. The Trump administration’s EPA committed last March to reconsider the standards as part of a broader deregulatory effort. American Trucking Associations requested a delay, while manufacturers opposed one because they were already retooling production lines and securing materials, said Patrick Kelly, ATA’s vice president of energy and environmental affairs.

EPA later informed ATA that it would still proceed with the 2027 NOx implementation while reevaluating warranty and useful-life provisions.

Kelly said manufacturers indicated the rule could add $10,000 to $20,000 to the cost of a new truck, although revisions under consideration could lower that figure.

“We were glad to see EPA commit to pulling that aspect back to what the warranties had been previously,” he said, noting that ATA has not yet seen a proposal.

That uncertainty makes long-term planning difficult for fleets that rely on predictable lifecycle costs. Until final rules are set, many operators are reluctant to commit capital to equipment that might carry higher maintenance exposure or weaker resale value later in its service life.

Manufacturers have told NationaLease they do not expect to finalize 2027 pricing until late in the third quarter or early in the fourth. Vicha said he does not anticipate a dramatic leap in technology but believes fleets will still approach the transition cautiously.

“I’ve experienced enough [cycles] to know it’s probably not going to be as good as they say it is, and it’s probably not going to be as bad as we think,” he said.

How fleets respond depends heavily on their scale, in-house capabilities and tolerance for risk. Larger leasing and rental providers are positioned differently than operators without nationwide service networks or extensive engineering resources.

Jim Lager, executive vice president of sales and rental at Penske, said fleets are paying close attention to the upcoming rule. The added cost and complexity could reinforce a trend toward leasing that has been building for years.

Still, he said tariff-related uncertainty and a soft freight market remain the bigger near-term concerns. Excess capacity continues to pressure the industry, although he believes conditions may be moving toward balance.

Penske’s early access to new equipment allows the company to evaluate serviceability, operational performance and resale implications. As emissions systems grow more complex, many customers prefer to rely on Penske’s maintenance infrastructure so they can focus on freight.

“[Customers are] going to continue to have a vehicle to operate,” Lager said. “We’re going to be the ones with the down trucks.”

The company does not plan to adjust its buying cycle and is not expecting a widespread pre-buy.

Still, Penske is watching maintenance and resale risks closely. New one-box aftertreatment systems will be sealed and nonserviceable, meaning a failure could require full replacement at significant cost. Such issues could surface deep into a truck’s life and affect resale demand.

For fleets considering ownership, that long-tail exposure is a significant part of the buy-versus-lease calculation. Leasing shifts responsibility for unexpected component failures and resale uncertainty from the fleet operator to the leasing provider, offering more predictable costs as new emissions technology rolls out.

Race Against the Clock

Beyond technology concerns, fleets also face timing pressure as manufacturers prepare for the 2027 transition and order boards tighten.

Vicha said some fleets may be better off buying trucks this year rather than waiting and being pushed into higher-priced, less-proven models manufactured in 2027. But he emphasized that NationaLease will not place orders without firm commitments.

If economic conditions improve this spring, he warned, order boards could fill quickly.

“I kind of see it as a game of musical chairs, and there’s four chairs and there’s six of us walking around,” Vicha said. “When is this going to happen? Because the OEMs aren’t going to crank up production. It’s too late.”

Brian Antonellis, senior vice president of fleet operations at Fleet Advantage, said his company expects to order 6,000 to 7,000 trucks this year. About 40% are pull-forward orders, purchasing 2026 equipment that otherwise would have been bought in 2027.

Those orders reflect rising capital costs and reliability concerns.

Pull-forward buying also fits a broader strategy: lock in known costs and proven equipment before new emissions systems arrive. That same risk-management logic is driving interest in shorter-term lease structures.

Antonellis said he does not expect the kind of widespread issues seen during earlier emissions transitions, although training needs and first-generation system challenges are likely.

“There’s going to be training,” he said. “There’s going to be technology adoption. I’m sure there’ll be a version one and a version two at a bare minimum.”

Daimler Truck Financial Services North America has not seen a major shift toward leasing as the primary acquisition method, CEO Kevin Bangston said. Many fleets continue to mix purchasing and financing approaches while remaining cautious.

With freight markets still soft, some fleets are delaying capacity additions and extending trade cycles, which results in older equipment and higher maintenance costs. Bangston said replacement strategies vary by segment, with refrigerated and flatbed demand recovering faster than box trucks.

“As these conditions normalize, we expect these trends to translate into increased interest in leasing,” Bangston said.
