How the estimates were built: data sources, modelling approach and validation steps.
Research approach
A market size is a claim about the world, and a claim is only as good as the route to it. Every study is built upward from units and prices — what is actually produced, sold or performed, at what it actually changes hands for — rather than from a headline figure divided downwards. Disclosed company revenue is then used to check that build, not to produce it.
The estimate is built upward from unit volumes and realised prices for off-road vehicle engines, starting with annual production and shipment counts by power band (under 50 horsepower, 50 to 100 horsepower and above 100 horsepower) drawn from engine manufacturers' reported unit shipments and construction and agricultural equipment production statistics. Average selling prices for each power band and fuel type are applied to convert those volumes into revenue, then adjusted for the mix of OEM-fitted versus aftermarket replacement units. That bottom-up build is then checked against the engine-segment or power-systems revenue disclosed by major manufacturers in annual filings; where the two diverge, the unit-volume or price assumption feeding the bottom-up build is corrected, not averaged against the disclosed figure.
The four stages
The same sequence runs behind every published study, whatever the industry. The order matters as much as the steps: the segment axes are fixed before any number is collected, so the model is never reshaped to fit whatever data happens to turn up.
What the build rests on, and what checks it
The two are not interchangeable. The left column produces the number; the right column tests it. When the check disagrees with the build, the answer is to find which bottom-up assumption is wrong — a unit count, a price, a take-up rate — not to split the difference between them.
- Volume actually transacted — units produced, installed, dispensed or procedures performed, counted at the level each is genuinely recorded
- Realised pricing by tier and channel, rather than one blended average applied across the whole market
- Take-up and frequency: how much of the addressable base buys, and how often it repeats
- Disclosed revenue of the companies serving the market, where filings separate it far enough to be usable
- Buyer-side spending totals — capital budgets, procurement lines, or the output of the end market the product is bought against
- Trade and customs flows, where the product crosses borders in a separately recorded form
Data sources
Published data establishes what happened. Only the people transacting in a market can say why, and what is about to change — so the two are collected separately and weighted differently.
- Commercial and product leadership at the companies that supply the market
- Procurement and specification leads at the organisations that buy it
- Distributors, integrators and channel partners, where the market is served indirectly
- Regulatory and standards specialists, where approval governs what can be sold at all
- Company filings, annual reports and investor disclosure
- Government statistics, customs records and regulatory registers
- Trade association output and standards-body publications
- Technical and peer-reviewed literature, where the market rests on a clinical or engineering claim
Interviews target procurement and fleet-engineering managers at construction and agricultural equipment manufacturers, engine product planners at OEMs, and channel managers at engine distributors and authorized service dealers who set specification and replacement decisions in this market. Regulatory affairs contacts at emission-certification bodies are also consulted to confirm compliance-tier timelines that affect replacement demand. Sampling emphasizes North America and Europe, where engine manufacturers and Tier 4 Final and Stage V certification activity concentrate, alongside China and India, where local engine producers and machinery assemblers serve the largest unit volumes. Aftermarket and rebuild-channel contacts in Latin America and the Middle East supplement this to capture regional replacement-cycle behavior outside the primary manufacturing centers.
Desk research draws on emission-certification registers maintained by the US EPA and the European Union's Stage V type-approval database, which list certified engine families and power ratings by manufacturer. Global trade data is reviewed under the relevant HS code for compression-ignition engines to track cross-border shipment volumes. Construction and agricultural equipment production statistics published by industry associations, including figures on machinery units built by power class, are cross-referenced against engine-fitment ratios. Publicly filed annual reports and segment disclosures from listed engine and equipment manufacturers supply revenue benchmarks used in the top-down check described above.
Desk research runs across proprietary research databases including Factiva, OneSource and Hoovers alongside the public sources above. Modelling and statistical validation are run in SAS and SPSS.
Forecasting
The forecast is not a growth rate applied to a base year. It is built from the drivers that are expected to change, each one stated so a reader can disagree with it.
The forecast is built from projected construction and agricultural equipment production volumes by power band, adjusted for the pace at which Tier 4 Final and Stage V compliance timelines force replacement of older engines in markets still transitioning to those standards. Pricing assumptions hold average selling prices close to flat within each power band, with mix shift toward higher-power and electronically controlled units driving most of the revenue growth. The forecast normalizes for the equipment-order backlog built up during recent supply constrained years, treating that catch-up demand as a temporary addition rather than a new baseline. For the forecast to hold, construction and farm capital spending must continue at a pace broadly consistent with the historical five-year average.
Triangulation and validation
No figure enters a report on the strength of one source. Where the two sizing routes disagree the difference is not averaged away — the assumption causing it is isolated, tested against a third independent measure, and either corrected or carried forward as a stated limitation. Historical years are back-tested against the growth actually recorded before any forecast is allowed to run forward from them.
Historical output for 2020 through 2024 is back-tested against recorded construction and agricultural machinery production growth for the same years to confirm the bottom-up build tracks realised equipment output instead of drifting from it. Segment-level share shifts, including the move toward higher power bands and Tier 4 Final and Stage V compliant engines, are reviewed against the primary interview findings described above before being carried into the forecast. Sensitivities are tested on the pace of emission-standard-driven replacement and on construction and agricultural capital spending growth, since those two assumptions account for most of the variance between the bull and bear cases.
Confidence and limitations
Where an estimate is firm and where it is not is stated rather than left to be inferred from the precision of the number.
Confidence is firmest for the power-band and fuel-type splits in North America, Europe and China, where emission-certification registers and listed manufacturers' disclosures give a direct read on unit volumes and revenue. It is weaker for aftermarket and rebuild-channel volumes in Latin America, the Middle East and Africa, where replacement activity is reported inconsistently and much of it passes through unlisted regional distributors. A structural risk to this estimate is a faster than assumed shift of compact equipment to electric or hybrid-electric power, which would pull unit volumes out of the under-50-horsepower band faster than current adoption data suggests.
