Porsche increases its Manthey Racing stake from 51 to 67 percent, registered on August 11, 2026. The move consolidates control and signals deeper integration, despite wider portfolio reviews.
The decision runs counter to expectations of a sale. Instead, Porsche doubles down on a proven performance partner to bolster product depth and protect capability in a challenging market.
Managing directors Nicolas and Martin Raeder see their combined holding fall from 40 to 33 percent. Each now owns 16.5 percent, preserving continuity in day-to-day operations.

Founder Olaf Manthey exits as a shareholder, relinquishing his nine percent stake. He remains an advisor, offering continuity of expertise while stepping back into retirement.
The mandate for Manthey expands beyond upgrade kits and track programs. It now covers highly limited “Few-Off” vehicle concepts, aligning road-car enhancements with competition-derived development.
The shift fits Porsche’s refocus under CEO Michael Leiters and the broader “Sportwagenschmiede ’35” strategy. Activities group into Performance, Exclusiveness, and Heritage, with Manthey central to Performance.
On the customer side, Manthey continues the popular Porsche Track Experience and manages the Porsche Endurance Trophy Nürburgring within NLS. It supports maintenance, parts, assembly, and delivery for the series.
The timing reflects disciplined consolidation. With the tuning market under pressure, tighter alignment offers economic stability and preserves specialist capability inside the brand’s ecosystem.
Broader motorsport headwinds offer context. Financial scrutiny is rising, evidenced by Williams’ recent financial focus and investigation concerns at Mercedes. Porsche’s move aims to preempt similar fragility.
Operationally, deeper integration should accelerate homologation, supply-chain leverage, and track-to-road feedback. The risk is cultural dilution, but advisory continuity and a clear remit mitigate that.
Expect more Manthey-branded kits, track-focused derivatives, and ultra-limited builds. The GT3-linked programs and Nürburgring activities remain core, reinforcing Porsche’s performance identity through difficult conditions.
