Motor Vehicle Manufacturing (United States) — NAICS 3361

A Histometrics rollup primer for public-market and private investors.

What this page is. NAICS (North American Industry Classification System — the standard the U.S. government uses to group businesses) code 3361 is a four-digit industry group that sits one rung above two five-digit industries: 33611 (cars and light-duty vehicles) and 33612 (heavy trucks). This primer's job is the contrast between those two children — how big each is, which way each is heading, who owns them, and how the money differs — and then the group as a whole. For company-by-company detail, go to the child primers (and the leaf 336110 / 336120 primers beneath them).

1. Overview

NAICS 3361 is "the factories that build complete motor vehicles" — everything from a battery-electric crossover to an 18-wheeler. It sits at the top of a much larger auto economy: the assembly plants here are a small, capital-intensive core resting on a far bigger web of parts makers (NAICS 3363), dealers, and lenders that federal data files under separate codes. Counting only the assemblers, the broader U.S. auto sector — parts, retail, service, and finance included — is on the order of 3–3.5% of gross domestic product (GDP, the total value of what the country produces) and supports roughly 11 million jobs [7].

The single most useful fact about this group is how lopsided it is. By revenue it is overwhelmingly a car-and-light-truck business — passenger cars, pickups, minivans, and sport-utility vehicles (SUVs) — with heavy trucks a small, very different sidecar. Cars and light-duty vehicles are about 92% of the group's shipments; heavy trucks are the other ~8% [1][3][5]. Revenue share understates the truck half's importance to everyone else: the American Trucking Associations puts truck-moved freight at 11.27 billion tons in 2024, 72.7% of national tonnage against a $906 billion freight bill [8]. The 8% builds the machines that carry the other 92% of the economy.

A trap both children now flag explicitly. This group counts domestic production, not the U.S. market. Americans bought about 16.2 million new light vehicles in 2025, but U.S. plants build only around 10 million a year, the balance imported [9][10]; on the truck side the standard market yardsticks span borders too — PACCAR reported 232,800 heavy-duty retail sales across the U.S. and Canada in 2025 [11]. Reading a sales number as a production number (or vice versa) is the commonest analytical error with this code, in both children.

One-line takeaway. Two capital-goods businesses under one roof: a giant, consumer-facing car-and-light-truck industry led by General Motors, Ford, Toyota, and Tesla, plus a small, freight-driven heavy-truck oligopoly led by Daimler Truck, PACCAR, Volvo, and Traton — with barely any company overlap between them.

2. What's inside — the two children and how they differ

NAICS 3361 contains exactly two industries. Each happens to be a "pass-through" with a single six-digit child of its own (336110 and 336120), so the five- and six-digit figures coincide; the real analysis is the comparison between the two families.

The contrasts worth internalizing:

• Cars dominate the money; trucks punch above their weight in plant count. Autos are ~92% of receipts from only ~67% of the plants — auto assembly plants generate roughly five times the revenue per plant of a truck plant, and pay their workers ~$118k versus ~$70k [3][4][5][6]. Yet the federal Small Business Administration sets "small" at 1,500 employees in both children [14]: on either side of the group, this is an industry of giants.

• Trucks are the more concentrated child, and it is not close. Four corporate groups build roughly 98% of North American Class 8 trucks [11][15], and the leader alone holds ~39.6% [13]; on the car side the leader holds ~17% and the top four hold 58.3% [3][12]. (Different measures and geographies — the point is the order of magnitude.) Crucially, the leaders don't overlap: the top car firms (GM, Ford, Toyota, Stellantis) are not the top truck firms (Daimler Truck, PACCAR, Volvo, Traton). The only company with a real foot in both is Tesla, via its electric Semi — a rounding error inside a far larger company. That non-overlap is why the combined group looks less concentrated than either child (see §8).

• Their cycles run on different fuel — and 2025 proved it. Car demand tracks consumers and rose 2.4% to 16.2 million units [9], while heavy-truck retail sales fell about 13% and truck-maker margins roughly halved [11]. Same year, opposite directions.

• Most of the value in this group is created outside it. Both children now quantify it: GM reports material cost at roughly two-thirds of automotive cost of sales [17], and PACCAR reports bought-in raw materials, processed materials, and finished components at roughly 85% of a new truck's cost [11]. NAICS 3361 is the final-assembly slice of a value chain filed mostly under other codes.

• Their customers are shaped differently. Cars sell to diffuse retail buyers; trucks sell to a customer base that is numerically very fragmented — nearly 580,000 active U.S. motor carriers as of June 2025, 91.5% of them running ten or fewer trucks [8] — but whose block orders come from a relative handful of large fleets.

• Both are being reshaped by the same policy levers (emissions rules, tariffs) on different clocks. Some shocks land on both at once — the EPA's February 2026 rescission of the greenhouse-gas endangerment finding covers highway vehicles of every size [16] — while the instruments that bite hardest differ: lost EV subsidies for cars, a pivotal 2027 emissions rule for trucks.

What the group excludes matters as much as what it includes: auto parts (NAICS 3363), truck bodies built on a purchased chassis (336211), truck trailers (336212), motor homes (336213), and motorcycles are all outside 3361 [18]. Read this group as "final vehicle assembly," not "the auto industry."

3. How big it is (this level's rollup figures)

These are the federal statistics for NAICS 3361 as a whole, from our ground-truth dataset. Reassuringly, the two children add up almost exactly to the group totals — a good sign the data is internally consistent.

"Plants" is a wider word than you think. The 331 establishments above are the federal establishment universe, not a count of vehicle assembly lines. On the car side alone, the Alliance for Automotive Innovation — using a narrower assembly-plant concept — counts 20 automakers operating 55 light-vehicle assembly plants in 15 states, against 222 Census establishments [4][7]. The gap is definitional, not an error: use Census figures for statistical comparison, industry counts when you mean physical assembly capacity.

Undercount caveat — it runs backward here. Many industries are undercounted because tiny or individual operators slip past the Census; motor-vehicle assembly is the opposite — a handful of huge, well-captured firms, so small/individual ownership is not a gap. The direction of error is understatement of footprint, not of firm count. These ~277,000 assembly jobs sit atop roughly a million total motor-vehicle-and-parts manufacturing jobs and an auto sector supporting ~11 million U.S. jobs [7]. Two further understatements specific to this group: much North American assembly (especially of trucks and of many light vehicles) happens in Mexico and Canada, outside U.S. counts; and the fattest profit pools — replacement parts and captive financing — are booked under other NAICS codes. No values above are suppressed; all are reported figures.

4. Investable universe — where value concentrates

Value in NAICS 3361 concentrates in two almost-separate rosters, one per child. There is no pure "motor-vehicle-manufacturing" exchange-traded fund (ETF — a fund that trades like a stock); you assemble exposure name by name or reach it through broad consumer-discretionary and industrial index funds.

On the car-and-light-truck side (33611), where ~92% of the money is [3]:

• U.S.-listed pure-play automakers: General Motors (GM) (~$185 billion of 2025 revenue [19], ~$68 billion of market value [20]), Ford (F) (a record $187.3 billion of revenue but an $8.2 billion net loss in 2025 [21], ~$56 billion of market value [20]), Tesla (TSLA) ($94.8 billion of revenue [22] and ~$1.3 trillion of market value [20]), and Stellantis (STLA) (~$30 billion [20]). Note the shape: revenue is spread across the legacy makers, market value is not.

• Speculative EV startups: Rivian (RIVN) and Lucid (LCID) delivered 42,247 and 15,841 vehicles in FY2025 [23] — rounding errors against a 16.2-million-unit market [9], and both burning cash.

• Foreign transplants that run some of America's biggest plants but list abroad or via American Depositary Receipts (ADRs — foreign shares wrapped to trade on U.S. exchanges): Toyota (TM), Honda (HMC). Their U.S. plants are inside the federal figures above; their shares are not part of the domestic auto-stock universe.

• Thematic funds (whole value chain, not pure assemblers): DRIV, KARS, IDRV.

On the heavy-truck side (33612), the other ~8% [5]:

• PACCAR (PCAR) — the one large, liquid, U.S.-listed truck maker (Kenworth, Peterbilt, DAF); $33.7 billion of revenue, $4.16 billion of net income and 185,300 trucks delivered worldwide in 2024 [11][24]. The cleanest direct way to own a heavy-truck original-equipment manufacturer (OEM).

• Daimler Truck (DTRUY), Volvo Group (VLVLY), Traton (8TRA) — the other three oligopoly groups, foreign-listed. Traton is 87.52% Volkswagen-owned with a 12.5% free float, which belongs in any governance or liquidity analysis [25].

• Cummins (CMI) and Allison Transmission (ALSN) — supplier-side exposure (engines and emissions aftertreatment; automatic transmissions weighted to vocational work).

• Rush Enterprises (RUSHA/RUSHB) — the dealer/service/aftermarket angle, and the largest U.S. commercial-truck dealer.

For private investors, note that direct ownership of an assembler is rare in both children — building vehicles is too capital-intensive. Private capital almost always sits around the OEM: parts suppliers, dealer and service groups, body/up-fit builders, leasing and rental fleets, and venture/private-equity stakes in EV, battery, charging, and autonomy startups. See §4 of each child primer for the full tables and scale figures.

5. How the money works

Both children are high-fixed-cost, cyclical assembly businesses: an owner earns the spread between a vehicle's price and its build cost, times volume, minus enormous fixed costs for plants, tooling, engineering, and labor. Because those fixed costs don't flex, capacity utilization is the swing factor — and the revised child pages now put hard numbers on that leverage:

• Cars & light-duty (33611): volume-driven, ~170 firms, average transaction prices that crossed $50,000 for the first time in September 2025 and set a record near $50,326 in December [26]. Mix decides everything: GM discloses that trucks, crossovers, and cars run at roughly 160%, 40%, and 60% of its weighted-average North American vehicle profit [17]. A good year is mid-single digits — GM's North America adjusted operating margin was 6.8% in 2025 (9.2% in 2024) [27] and Ford's company-wide adjusted margin 3.6% [21]. The live drag is EVs: Ford's Model e segment ran at −72.1% [21] and GM took $7.6 billion of EV-related charges in 2025 [19]. Captive finance (GM Financial, Ford Credit) smooths the cycle; regulatory-credit sales are near-pure margin but shrinking as rules loosen — Tesla booked ~$1.99 billion, down 28% [22]. Detail in the 336110 primer §5.

• Heavy trucks (33612): build-to-order capital goods; a new Class 8 sleeper runs roughly $170,000–$200,000, and building it earns thin margins that vanish at the bottom of the cycle. PACCAR's worldwide truck gross margin fell from 13.9% in 2024 to 7.5% in 2025, truck pretax return on revenue from 11.5% to 4.5%, on U.S./Canada truck revenue down from $15.39 billion to $11.35 billion [11]; at International Motors, adjusted operating return on sales fell from 6.5% to 0.1% as unit sales dropped from 79,300 to 50,112 [25]. The durable profit is aftermarket parts — PACCAR Parts turned over $6.67 billion in 2024, about 24% of company revenue — plus captive financing (PACCAR Financial financed 27.0% of new PACCAR truck sales in 2025) [11][24]. Detail in the 336120 primer §5.

Common thread for investors: in both children the manufacturing is the low-margin part, and the parts-and-finance annuity is where steady money hides — much of it, unhelpfully, booked outside NAICS 3361. The 2025 results also show the two children can compress margins in the same year for completely different reasons: tariffs and EV write-downs on the car side, a freight recession on the truck side.

---

6. Demand drivers

The two children run on different demand engines, which is why the group's revenue is steadier than either child alone:

• Cars & light-duty: the consumer economy and jobs, interest rates and affordability (most vehicles are financed, and with transaction prices above $50,000 the mass-market buyer is stretched [26]), the replacement cycle (the average U.S. vehicle reached 12.8 years in 2025 [28]), fuel prices shifting the car-versus-truck mix, and tax/incentive policy. Policy moves demand violently: the federal EV purchase credit expired September 30, 2025 [29], battery-EV share spiked to a record 12% that month and then fell below 6% in each remaining month of the year; for 2025 as a whole, hybrids, battery-EVs, and plug-in hybrids together made up about 22% of light-duty sales [30]. Full-year volume was nonetheless calm — up ~2.4% to 16.2 million [9]. The mix whipsawed; the total did not.

• Heavy trucks: freight volumes and carrier profitability (ACT Research describes 2025 as a prolonged downcycle of weak freight, poor carrier margins, and defensive replacement-only buying [31]), the fleet replacement cycle, and regulatory pre-buys (fleets ordering ahead of a costly new emissions rule). One caution the revised child adds: the order board is not a clean leading indicator — it has to be decomposed into regulatory pull-forward, cancellations, and genuine fleet expansion. Vocational demand (construction, refuse, utility) is steadier than long-haul freight.

See §6 of each child primer.

7. Regulation

Motor-vehicle assembly is among the most heavily regulated industries in America, and both children are being reshaped by the same 2025–26 policy swings — on different clocks. One action hit both at once: in February 2026 the Environmental Protection Agency (EPA) finalized the rescission of the greenhouse-gas endangerment finding and repealed federal GHG standards for highway vehicles, leaving traditional air-pollutant rules in force [16]. Beyond that, the instruments diverge:

• Cars & light-duty: the National Highway Traffic Safety Administration proposed in December 2025 rolling Corporate Average Fuel Economy (CAFE) standards back to roughly 34.5 mpg by model year 2031, from a prior trajectory near 50 mpg [32]; Congress revoked California's Clean Air Act waivers in June 2025, ending the basis for state EV sales mandates [33]; a 25% Section 232 tariff took effect on imported vehicles April 3, 2025 and many parts May 3 [34], costing GM alone $3.1 billion in 2025 material and freight [17]; the $7,500 EV credit ended September 30, 2025 [29]; and United Auto Workers contracts (roughly 25% base-wage increases through April 2028) govern Detroit Three plants [35]. Detail: 336110 primer §7.

• Heavy trucks: the EPA 2027 NOx rule (a 0.035 g/hp-hr oxides-of-nitrogen limit from model-year 2027) keeps its start date and limit [36], though EPA published proposed amendments on July 14, 2026 to useful life, warranty, testing and penalties that are not yet final [37]; Congress's 2025 revocation of EPA waivers also killed California's Advanced Clean Trucks and Omnibus low-NOx rules [38]; and a separate 2025 proclamation imposed a 25% tariff on covered imported medium- and heavy-duty trucks and parts, with an offset tied to U.S. assembly [39]. Detail: 336120 primer §7.

The shared lesson for investors is that regulatory whiplash is itself a risk in this group — the rules governing product design, cost, and the timing of demand changed sharply in a single year, in both directions, and parts of the truck framework remain unsettled.

---

8. Consolidation

At the group level the federal data reads as moderately concentrated:

Why the group looks less concentrated than either child — the counter-intuitive part. Combining two industries with different market leaders dilutes the top-4 share: the four biggest carmakers and the four biggest truck makers are eight different companies, so no single four-firm set dominates the merged $390B. That's why the group's CR4 (53.3%) sits below the car child's (58.3%) and well below the truck child's (76%), and why the group HHI (~1,018, the low end of "moderately concentrated") is below the car child's ~1,186. (The truck child's HHI is suppressed in federal data, so we do not state a value.)

The revised children make the shape of each market concrete. In cars, no one is close to dominant: registration data puts GM at 17.4%, Toyota at 16.5%, and Ford at 12.6% [12] — and even that depends on the yardstick, since GM's own 10-K reports 17.2% on a sales basis [17]; manufacturer sales, registrations, and fleet deliveries are not interchangeable. In trucks, four groups build roughly 98% of North American Class 8 [11][15], with approximate 2025 U.S./Canada retail share of Daimler ~39.6% [13], PACCAR ~29.9% and Volvo plus Mack ~17.8% [40], and International ~11–13% [25]. The takeaway: this group is not one market but two adjacent oligopolies — Detroit-plus-transplants in cars, a four-group oligopoly in trucks — whose competitive stories are told separately in the child primers §8.

---

9. Risks

The group inherits both children's risks, and they largely rhyme:

• Deep cyclicality amplified by high fixed costs — different cycles, comparable amplitude. Car sales ran 16.2 million units in 2025 against a 10.2 million trough in 2009 [9][41]; heavy-truck margins roughly halved in a single year, and 2026 is forecast lower still [11][31].

• Trade and tariff exposure — two separate 25% tariff regimes now cover light vehicles and parts [34] and medium/heavy trucks and parts [39], on top of heavy cross-border (Mexico/Canada) assembly.

• Money-losing, uncertain-payoff EV transition — acute for cars now (GM's $7.6 billion of charges; Ford Model e at −72.1%) [19][21]; earlier and differently constrained for trucks, where the grid is the binding limit: a Department of Energy assessment puts an 80% recharge in twenty minutes at up to 3.5 megawatts per truck and 25–125 megawatts for a full site [42].

• Regulatory reversals — the same whiplash that helps one year can hurt the next, and the truck side still faces unfinished rulemaking.

• Foreign competition and ownership — cost-advantaged Chinese makers pressure cars in export markets; three of the four truck groups are foreign-owned, and Traton's 12.5% free float is its own governance and liquidity question [25].

• Supply-chain single-point failures and labor — a single aluminium-supplier fire cost Ford about $2 billion in 2025 [43]; the truck child adds engine, semiconductor, axle and rare-earth dependencies, and both face collective-bargaining risk, with the next UAW contract expiry in 2028 [35].

• Customer structure — the revised truck child sharpens the parent's old claim. The truck customer base is not concentrated at all (~580,000 carriers, 91.5% running ten or fewer trucks [8]); what concentrates is order flow, in the large fleets whose block orders swing a quarter. Car demand is diffuse retail with fleet buyers at the margin.

The one genuinely diversifying feature is in §6, and 2025 is the proof: cars up 2.4% while heavy-truck retail fell ~13% [9][11]. Because cars and trucks answer to different demand engines, a bad freight year and a bad consumer year don't always coincide. See §9 of each child primer for the detail.

10. How to invest & outlook

How to invest. There is no single-ticker or single-ETF way to own NAICS 3361; you build it from the two children.

• Public, car side: cheap dividend-paying legacy makers (GM, Ford, Stellantis), growth-priced Tesla, speculative EV pure-plays (Rivian, Lucid), foreign makers via ADRs, or thematic EV funds (DRIV, KARS, IDRV).

• Public, truck side: PACCAR (PCAR) as the clean pure play, Cummins (CMI) and Allison (ALSN) for supplier exposure, Daimler Truck / Volvo / Traton via ADRs or European listings, Rush Enterprises for the dealer/aftermarket angle.

• Private: rarely the assembler itself — reach the group through suppliers, dealer groups, leasing fleets, body builders, used-vehicle remarketing, and EV/battery/charging/autonomy ventures.

Outlook (forward-looking judgment, not a forecast of record). The two halves are on offset clocks. Cars are a mature, cyclical industry with real crosscurrents: a cost tailwind from looser fuel-economy and emissions rules, offset by higher tariffs, lost EV subsidies, stretched affordability, and money-losing EV programs — net, choppy; the winners hold pricing, keep plants full, and tilt mix toward trucks and SUVs. Trucks are climbing out of one of their deepest downcycles: ACT Research projects roughly 171,000 Class 8 units in 2026 (down ~18%) before recovery, even as December 2025 order boards hit a three-year high on EPA-2027 pre-buying [31][44] — expect soft deliveries into 2026, a pre-buy bump around 2027, then an air-pocket. Through all of it the structural story holds: two stable oligopolies whose parts-and-finance profits cushion a brutal new-vehicle cycle, with electric-vehicle adoption on both sides now markedly less policy-driven than it looked two years ago. Because the money is ~92% cars, the group's fortunes will track the consumer-vehicle story first and the truck cycle second.

For the full detail on either half, read the child primers — this page is the bridge between them.
