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: annual convertible and retractable-roof vehicle production by body style and roof type, multiplied by the average realized price of each roof system as fitted at the factory. Volumes are taken by vehicle platform and cross-checked against known model-year production runs for the sports-car and specialty-vehicle segments that carry most of this category. Realized prices are set per mechanism type, since a power-operated hardtop system commands a materially higher unit price than a manual soft top. The build is then checked against the roof-and-closure-systems revenue Webasto, Magna International and Inalfa Roof Systems disclose in their own segment reporting; where the two diverge, the bottom-up unit-price or volume assumption is the one 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.

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

Primary input comes from three roles: engineering and procurement contacts at OEMs who set roof-system specifications and sourcing volumes, commercial and program managers at the tier-one roof suppliers who see order books across multiple vehicle platforms, and aftermarket and bodyshop contacts who see replacement and retrofit demand once vehicles age past warranty. Sampling weights toward Germany and Italy, where most sports-car and convertible-platform sourcing decisions are made, with additional coverage in the United States for the North American mid-size convertible segment and in China for the fast-growing premium segment there. Regulatory contacts are included only where roof-system or rollover-protection standards affect design choices.

Secondary sources, this report

Desk research draws on vehicle homologation and type-approval filings that record roof-system configuration by model variant, national vehicle registration statistics broken out by body style, and the supplier segment disclosures Webasto, Magna International and Inalfa Roof Systems publish in their annual reporting. Import and export customs data under the relevant automotive parts tariff codes is used to cross-check component trade flows between the European supplier base and assembly plants in North America and Asia Pacific. Trade-body production statistics from national automotive manufacturer associations supply the vehicle-platform volumes that anchor the unit 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 the pace at which OEMs convert convertible platforms from manual and simple soft-top mechanisms to power-operated and retractable hardtop systems, and from the rate at which premium and mid-size sports-car production expands in Asia Pacific relative to its established base in Europe and North America. Pricing is held to decline gradually in real terms as mechanism manufacturing scales, offsetting some of the volume gain. The 2020-2021 production trough tied to pandemic-era output disruption is treated as an anomaly and is not projected forward; the base year onward assumes production volumes normalize to their pre-disruption trend.

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

Outputs are back-tested against recorded convertible and retractable-roof vehicle production growth over 2020-2025 to confirm the forecast slope is consistent with the category's actual recovery path. Segment-share shifts, including the move toward power-operated mechanisms and the rising share of Asia Pacific production, were reviewed against supplier order-book commentary to confirm direction and rough pace. Sensitivities were run on the two assumptions most likely to move the total: the pace of hardtop conversion and the rate of premium-segment growth in China, since a slower conversion pace or a China slowdown would each pull the 2034 total down by a similar order of magnitude.

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 strongest for the Europe and North America totals and for the power-operated mechanism share, where supplier disclosures and vehicle registration data point the same direction. It is weaker for the Asia Pacific build, where fewer suppliers report roof-system revenue separately from broader closure-systems segments, and for the aftermarket channel, where replacement volumes are not centrally reported. A shift in premium-vehicle production policy in China, or a faster-than-modeled move away from convertible body styles generally, are the two risks most likely to force a revision.
