Porsche has increased its stake in Manthey Racing to 67%, giving the sports-car manufacturer a two-thirds holding in the German motorsport and performance specialist.
The companies announced the ownership change on 8 October 2026. Porsche previously held 51% of Manthey, a position acquired in 2013, so the transaction increases rather than initiates the manufacturer's control of the business.
Ownership expands around Porsche's performance strategy
Porsche places the increased shareholding within its new Home of Sports Cars strategy and, specifically, the Sportwagenschmiede '35 programme. The company says the closer relationship will support additional special models, performance kits and exclusive track experiences.
Those plans connect Manthey's competition operation with road-car products and customer activities. The Meuspath business runs programmes in championships including the FIA World Endurance Championship and DTM, while its wider work includes vehicle development, track support and Porsche-approved performance parts.
Porsche says the partners have developed nine performance kits since 2020 across the 911, 718 and Taycan ranges. That is a company-supplied total. The official announcement does not provide sales volumes, revenue contribution or margins for those products, so MRI has not inferred the financial scale of the programme.
The two businesses also cite Manthey's 30 years of GT racing experience and a record including seven overall victories at the Nürburgring 24 Hours, six Le Mans class wins and championship titles in the World Endurance Championship and DTM. Those achievements explain the technical and commercial fit, but they do not establish the value of the latest transaction.
Two-thirds holding formalises a broader operating link
Moving from 51% to 67% gives Porsche a larger economic interest and a two-thirds ownership position. The announcement does not disclose the seller, purchase price, valuation, payment structure or whether the deal requires further approvals. It also does not explain any change to Manthey's board, management authority, workforce or remaining shareholders.
Porsche chief executive Michael Leiters described Manthey as an important partner in the company's plan to bring motorsport-derived products and experiences to customers. Nicolas and Martin Raeder, Manthey's managing directors, said the increased participation would enable the companies to intensify their collaboration. MRI has paraphrased those statements rather than reproducing the official quotations.
The companies plan to show an initial preview of future joint projects at the DTM event in Hockenheim on 9 October. That preview may provide the first indication of whether the next phase centres on a road-legal special model, an additional performance kit, a track product or another format. The release itself does not specify the project.
For the motorsport supply chain, the substantive change is the deeper integration of a manufacturer with a specialist that turns racing knowledge into competition programmes, engineered components and customer experiences. It potentially creates a more direct route from Manthey's track work into Porsche product planning, but neither company has announced new facilities, headcount, supplier awards or race entries as part of this transaction.
