Methodology

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.

Market size estimation, this report

The estimate is built upward from unit volumes: global vehicle production and parc size by region, the average number of steering and suspension parts fitted or replaced per vehicle, and realized OEM and aftermarket prices for each part category. That bottom-up build is then checked against disclosed revenue from the named suppliers active in steering and suspension. Where the two disagreed, the correction was made to the bottom-up assumption, most often the per-vehicle fitment rate or the replacement-cycle length, rather than to the supplier revenue figures used as the check. Passenger and commercial vehicle production are modeled separately because fitment rates and part durability differ materially between the two.

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.

The bottom-up build rests on
  • 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
The build is checked against
  • 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.

Primary — who is interviewed
  • 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
Secondary — what is read
  • 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
Primary research design, this report

Interview targets are the roles that actually set volumes and prices in this market: procurement and product-planning staff at OEMs and tier-one suppliers, engineering leads responsible for steering and suspension platform decisions, and purchasing managers at aftermarket distributors and large fleet operators who drive replacement-cycle timing. Sampling is weighted toward the regions carrying most vehicle production and component sourcing, Asia Pacific, North America and Europe, with additional coverage in Latin America and the Middle East and Africa to capture replacement-channel behavior in markets with older vehicle parcs.

Secondary sources, this report

Desk research draws on vehicle production and registration data from national transport authorities and OICA, HS trade-code records for steering and suspension component imports and exports, supplier annual filings for the named companies in this market, and aftermarket benchmark data published by industry trade bodies such as MEMA. Component-type-approval and safety registers were used to cross-check which part categories are mandated across regions, which affects fitment-rate assumptions used in the bottom-up build.

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.

Forecast approach, this report

The forecast is built from vehicle production trajectories by region, the pace of electric power steering and adaptive suspension adoption, replacement-cycle length by vehicle age, and the rate of material substitution toward aluminum and composites. The 2020-2021 production disruption is normalized out of the historical base so that recovery-driven growth in those years does not overstate the underlying forecast trend. The forecast holds if vehicle production continues its regional pattern and electric steering adoption proceeds at the pace observed in recent platform launches.

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.

Validation, this report

Historical 2020-2024 estimates were back-tested against recorded vehicle production and parts trade volumes to confirm the bottom-up build tracks actual activity. Segment share shifts, particularly the move toward independent suspension and electric steering, were reviewed against platform-level product plans. Sensitivity was tested against two variables most likely to move the forecast: vehicle production growth by region and raw material price movement, since both feed directly into the unit-price assumptions underlying the build.

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 framing, this report

Confidence is firmest for the overall 15-year total and the product-category split, since both rest on production-based unit counts checked against disclosed supplier revenue. It is softer for the country-level splits within each region and for the 2020-2025 growth rate on the four secondary segmentation axes, which rely more on proxy trade-flow and production-share data than on direct disclosures. A sustained multi-year decline in vehicle production, or an electric power steering transition materially faster than current platform launches suggest, are the two developments most likely to require a revision.
