Every customer I’ve talked to in the last 60 days has asked me some version of the same EPA 2027 truck pre-buy question: “Richard, do I lock in a 2026 now, or do I wait for the 2027s?” There’s no clean answer. But there’s a clear way to think about it \u2014 and one specific data point that’s telling us more than the press releases are. Let me walk you through it. This is a straight-talk look at what’s driving 2027 truck prices, why the warranty number is telling us something important, and what it means for your fleet planning over the next 18 months.<\/p>\n\n\n\n

\"EPA
The new Mack MP13 (2027) inside an EPA27-compliant Granite chassis at ACT Expo 2026. It looks the part. The question is what it costs you \u2014 and how it’ll run on a refuse route in year three. <\/figcaption><\/figure>\n\n\n\n

First, the facts as of today <\/h2>\n\n\n\n

Here’s what every fleet operator researching an EPA 2027 truck pre-buy needs to know as of today.. The standard cuts allowed NOx emissions by about 82 percent versus today’s trucks.1<\/sup> Every major OEM \u2014 Cummins, Volvo, Mack, Detroit, International, PACCAR \u2014 has now publicly committed engines for it. Order banks for Volvo D13 and Mack MP13 open in August 2026; Detroit Gen 6 starts production in January 2027. <\/p>\n\n\n\n

Don’t confuse this rule with the May 15 EPA announcement delaying light- and medium-duty Tier 4 <\/em>standards to MY2029.2<\/sup> That’s a different program. The 35 mg\/hp-hr heavy-duty NOx limit is not being repealed.<\/p>\n\n\n\n

One important caveat \u2014 <\/strong>Reuters reported May 5 that EPA is preparing a draft rule revision (NPRM) expected in late June 2026<\/strong>.3<\/sup> Industry reporting says the 35 mg NOx limit stays, but EPA may soften the new warranty and useful-life rules <\/strong>that have driven up 2027 truck pricing. If you have a major order pending, that NPRM is worth watching before you sign.<\/strong><\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n

The warranty number is telling us something<\/h2>\n\n\n\n

Here’s the data point I want every customer to understand. Under the current rules, an emissions-system warranty is 100,000 miles<\/strong>. Under EPA 2027, that warranty jumps to 450,000 miles<\/strong>. The defined useful life of the engine goes from 435,000 miles to 650,000 miles<\/strong>. This is the single biggest cost driver in any EPA 2027 truck pre-buy decision.<\/p>\n\n\n\n

Now think like a manufacturer. If I’m Cummins or Detroit and the government just told me I have to warrant an emissions system \u2014 which is one of the least reliable parts of a modern diesel \u2014 for 4.5 times longer <\/strong>than I do today, what do I do? I price the risk in. Every DPF failure, every DEF sensor, every SCR module, every EGR cooler that fails between 100,000 and 450,000 miles is now my problem<\/em>, not the customer’s. <\/p>\n\n\n\n

\u201cThe truck makers are telling us how nervous they are about these engines \u2014 by how much money they’re putting aside to warranty them.\u201d<\/strong><\/strong><\/p><\/blockquote>\n\n\n\n

That’s exactly what’s happening. Industry estimates for the 2027 sticker premium range from $8,000 to $25,000 per truck<\/strong>, with most vocational analysts landing in the $15,000-$20,000 range for refuse and roll-off configurations.5<\/sup> ACT Research said in February that those higher prices are now \u201ceffectively locked in\u201d even with regulatory uncertainty.6<\/sup> <\/p>\n\n\n\n

The thing I want you to sit with: that premium is not mostly the cost of new hardware<\/strong>. The 48-volt heaters, the dual-SCR modules, the extra sensors \u2014 those are real but they’re a fraction of the increase. The bulk of the premium is the OEMs pricing in repair risk <\/em>over the next 450,000 miles. That tells you exactly how confident they are in the new aftertreatment systems. Not very. <\/p>\n\n\n\n

EPA 2027 Truck Pre-Buy: The Honest Tradeoffs<\/h2>\n\n\n\n
PRE-BUY MY2026 NOW 
Pros <\/strong>
\u203a Known quantity. <\/strong>2026 trucks use engines that have been on the road for years. The X12, X15, DD15, MP8, D13 \u2014 we know their failure modes, their service costs, and which parts wear first. 
\u203a Lower acquisition cost. <\/strong>$8K-$25K less per truck means $80K-$250K saved on a 10-truck order. That’s real money for residual planning. 
\u203a Body builders are ready today. <\/strong>Heil, 
McNeilus, New Way, Galbreath \u2014 all have current chassis specs nailed down. No 
surprises on hoist clearance, PTO routing, or aftertreatment packaging. 
\u203a Residual value upside. <\/strong>History repeats itself. The 2006 pre-EGR Macks, the 2009 pre-DPF Petes \u2014 those trucks held value for a decade because operators trusted them. A clean 2026 has a good shot at the same story. 
\u203a Drivers know the trucks. <\/strong>Your techs are trained, your fleet software is configured, your parts inventory is right. 
Cons <\/strong>
\u203a Build slots are tight. <\/strong>If you wait until 
November to decide, you may not get a 2026 build slot at all. 
\u203a Older emissions hardware. <\/strong>Today’s 
DEF\/DPF\/SCR systems still cause downtime. You’re not buying a problem-free truck \u2014 you’re buying a known problem. 
\u203a You’re not future-proof. <\/strong>Eventually you have to transition. Pre-buying delays the 
learning curve, it doesn’t eliminate it.<\/td>		WAIT FOR THE 2027
Pros <\/strong>
\u203a Cleaner emissions performance. <\/strong>82% NOx reduction. Better story for municipal 
customers and ESG-conscious haulers. 
\u203a Longer warranty coverage. <\/strong>If the new 
systems hold up, you get 450K miles of 
emissions warranty instead of 100K. That’s the OEMs assuming repair risk you used to carry. 
\u203a Potential fuel economy gains. <\/strong>Mack says +3% on the MP13. Detroit and Volvo claim similar. On a refuse truck running 25,000 miles a year, that’s real. 
\u203a Modern electronics and software. <\/strong>Better diagnostics, predictive maintenance, 
telematics integration. 
Cons <\/strong>
\u203a First-year technology risk. <\/strong>No 
2027-compliant engine has a customer fleet pilot on the road as of today. Every one of these engines is new architecture \u2014 48V 
electric heaters, twin-module SCR, integrated DEF dosers. 
\u203a Higher upfront cost. <\/strong>$8K-$25K more per truck. On a 10-unit order that’s a 
quarter-million dollars. 
\u203a Body builder books not finalized. <\/strong>2027 vocational chassis layouts aren’t fully 
published. Roll-off hoist integration may have surprises. 
\u203a Reliability is a question mark. <\/strong>The warranty pricing tells us the OEMs are nervous. We can hope these engines run reliably over time \u2014 we can’t yet prove it.<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n

What happened to pre-emission truck prices<\/h2>\n\n\n\n
\"pre-emission
Trucks like this 2006 Mack CV713 still command strong prices 20 years later \u2014 because operators know they run.<\/figcaption><\/figure>\n\n\n\n

Look at the used market today. A clean, well-maintained pre-EGR Mack from 2006 <\/strong>or a pre-DPF Peterbilt from 2009 <\/strong>still pulls strong dollars two decades later. Why? Because the market has voted on reliability. Those trucks proved themselves, and proven reliability sets the price.<\/p>\n\n\n\n

Here’s what I expect to happen with current pre-2027 chassis prices: they go up, not down<\/strong>. As 2027 build slots tighten and customers see the warranty-driven premium on new trucks, demand for clean late-model 2024-2026 units will firm up. We saw exactly this pattern in 2007 and 2010 \u2014 every prior emissions transition has produced a 3-5 year window where pre-rule trucks held a meaningful price premium in the used market.<\/p>\n\n\n\n

If you own a fleet of 2024-2026 trucks today and you take care of them, that value is going to hold. And if you’re sitting on the fence about pre-buying, just understand that the 2026 you buy in August at $X is likely worth somewhere close to $X for the next two to three years on the used market \u2014 provided you keep the maintenance records clean.<\/p>\n\n\n\n

Can we trust the 2027 engines?<\/h2>\n\n\n\n

Honestly? We don’t know yet. As of today \u2014 May 18, 2026 \u2014 there is not a single 2027-compliant
heavy-duty engine in a paying customer’s fleet. Not one. Every truck the OEMs have shown is an
engineering or validation unit. There is no real-world refuse-route data, no roll-off duty cycle data, no
cold-start data outside controlled environments.<\/p>\n\n\n\n

The new aftertreatment systems are also more complex than what we run today. Each OEM took a different
route. Here’s how the major engines line up \u2014 and the truck brands you’ll see each one in:<\/p>\n\n\n\n

CUMMINS X10<\/span> \u2014<\/span><\/h3>\n\n\n\n

Peterbilt, Kenworth, Freightliner vocational, Mack (optional), Autocar refuse. Uses a 48-volt
electrical system to heat its emissions components quickly during cold starts. Useful for over-the-road, but
unproven on a refuse truck that spends its life at idle and low load.<\/p>\n\n\n\n

VOLVO D13 (2027) \u2014<\/span><\/h3>\n\n\n\n

Volvo VHD and VNR vocational. Dual-SCR modules with electric heaters. Order
banks open August 2026, MY2028 production.<\/p>\n\n\n\n

MACK MP13 (2027) \u2014<\/span><\/h3>\n\n\n\n

Mack Granite, LR refuse, Pinnacle. Same dual-SCR family as the Volvo D13 (shared
Volvo Group architecture). Order banks August 2026, MY2028 production. Mack claims roughly +3% fuel
economy.<\/p>\n\n\n\n

DETROIT DD13 \/ DD15 GEN 6 \u2014<\/span><\/h3>\n\n\n\n

Freightliner Cascadia, M2, 114SD, 122SD vocational, Western Star
47X\/49X. Went the opposite direction with a pre-SCR architecture that skips the 48V system altogether.
First production January 2027 \u2014 the hardest delivery date in the industry.<\/p>\n\n\n\n

INTERNATIONAL S13 INTEGRATED POWERTRAIN \u2014<\/span><\/h3>\n\n\n\n

International HV, HX vocational, MV medium-duty.
Built on Scania DNA out of Huntsville. Single dosing module, no EGR cooler \u2014 a simpler design they argue
will be more reliable in vocational duty. Dealer training late 2026.<\/p>\n\n\n\n

PACCAR MX-13 (2027) \u2014<\/span><\/h3>\n\n\n\n

Peterbilt 567\/520, Kenworth T880\/T280 vocational. Architecture details still
under wraps. PACCAR is the quietest of the group on 2027 specifics, but order banks are expected in the
second half of 2026.<\/p>\n\n\n\n

Five different design philosophies. Five different bets<\/strong><\/h3>\n\n\n\n

All launching in the same twelve-month window. Somebody is going to be wrong<\/strong> about which approach holds up best in vocational and refuse service \u2014 and
we won’t know who until trucks have 100,000 miles on them.<\/p>\n\n\n\n

We can hope that all five architectures prove reliable over time. We can hope that the warranty premium is
just nervous OEMs over-pricing the risk. But if these manufacturers are building that much cost into the
sticker to cover a 450,000-mile warranty obligation \u2014 what are they telling us about the reliability they
expect? That’s a question worth asking your dealer rep directly.<\/p>\n\n\n\n

So What Should You Actually Do About Your EPA 2027 Truck Pre-Buy?<\/h2>\n\n\n\n
If you operate\u2026<\/span><\/td>What I’d do<\/td><\/tr>
High-uptime municipal refuse routes
Strict SLA, can’t tolerate downtime<\/td>		Pre-buy MY2026 chassis now. Lock in 2026 builds for your
critical fleet. Don’t put first-year 2027 tech on your most
important routes.<\/td><\/tr>
Growing fleet with mixed routes
Some flex, some learning tolerance<\/td>		Split your order. Pre-buy MY2026 for the core fleet, pilot 2-3
MY2027 units in less-critical service to build operational
familiarity before full transition.<\/td><\/tr>
New fleet build or long-term residual
focus
10-year horizon, ESG-aware customers<\/td>		Wait for the August order banks. Watch the late-June EPA
NPRM first \u2014 warranty rules may relax, repricing the deal.
Then commit to MY2028 builds with the new engines.<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n

The bottom line<\/h2>\n\n\n\n

2027 emissions are coming. The 35 mg NOx limit is staying. But the warranty number and the sticker
premium together are telling us a real story: the truck makers themselves are pricing in significant reliability
uncertainty. That doesn’t mean the new engines will fail \u2014 it means even the people building them aren’t
sure yet.<\/p>\n\n\n\n

For most of my refuse and roll-off customers, my recommendation is the same as it was in 2006 and 2009:
pre-buy what you need for the next 24 months, then pilot the new tech carefully before you commit your
whole fleet to it. Watch the late-June EPA rule revision. And keep your 2024-2026 trucks running clean \u2014
that fleet is going to be worth more than you think.<\/p>\n\n\n\n

I’m watching the order banks, the spec sheets, and the first customer deliveries every week. The moment a
real 2027 truck hits a real refuse route, I’ll let you know how it’s running. Until then \u2014 call me, and we’ll spec
your next order around what you actually need, not what a press release says you should want.<\/p>\n","protected":false},"excerpt":{"rendered":"
