Rolf Sprenger
A Pioneer in Porsche’s Customization Legacy
Introduction
Few names in Porsche’s history are as synonymous with exclusivity and bespoke craftsmanship as Rolf Sprenger. A visionary engineer and innovator, Sprenger played a pivotal role in shaping the personalization and limited-edition programs that define the Porsche brand today. His career spanned decades, leaving an indelible mark on the company through groundbreaking projects that turned customer dreams into reality.
Early Life and Passion for Porsche
Born in Stuttgart, Germany, Rolf Sprenger grew up in a city steeped in automotive excellence. From a young age, he was fascinated by the sleek sports cars that roamed the streets, particularly the Porsche 356. He dreamt not only of sitting in one but of one day owning a Porsche himself. This passion for the brand was the spark that would ignite a lifelong career in automotive engineering.
Education and Early Career
Pursuing his passion, Sprenger studied Mechanical Engineering at the Konstanz University of Applied Engineering. His early career saw him working as an automobile test engineer at Bosch in Stuttgart. His expertise in fuel injection technology led him to Simms in London, where he contributed to the development of diesel fuel injection systems.
Despite receiving an offer from Mercedes-Benz, he chose a different path, working briefly at NSU before joining Porsche in July 1967.

Joining Porsche: A Vision for Customization
Sprenger’s initial role at Porsche was within the motor test department in Zuffenhausen. He reported to senior engineer Hans Klauser, but it wasn’t long before his talent was recognized. At just 28 years old, he was promoted to lead the ‘Werksreparaturabteilung’—the factory repair department—where he handled special requests from Porsche customers worldwide.
Ferry Porsche himself entrusted Sprenger with the task of assisting customers who sought unique modifications and enhancements. This position allowed him to work closely with key figures such as Ernst Fuhrmann and Peter W. Schutz, further cementing his influence within the company.

Founding the Special Requests Department
As the demand for personalized Porsche vehicles grew, Sprenger envisioned a dedicated division that would cater exclusively to bespoke modifications. His persistence paid off, and in 1978, Porsche officially established the special requests department. This division laid the groundwork for what is now known as Porsche Exclusive Manufaktur, a program that continues to produce some of the most sought-after custom Porsche models today.
The department was responsible for executing unique customer requests, from custom interiors and paintwork to performance enhancements and one-off vehicle builds. This initiative solidified Porsche’s reputation as a brand that valued customer individuality and engineering precision.
Notable Projects and Limited-Edition Creations
Throughout his career, Sprenger oversaw numerous high-profile Porsche projects, including limited-series models and one-of-a-kind commissions. Some of the most remarkable vehicles associated with his tenure include:
- Porsche 993 Speedster (1995): Only two units of this rare model were produced. One was presented to Ferdinand Alexander “Butzi” Porsche for his 60th birthday, while the second became part of Jerry Seinfeld’s renowned Porsche collection.
- Street-Legal Porsche 935 (1983): This unique car started as a Porsche 930 Turbo before undergoing an extensive transformation to become a road-going version of the Porsche 935 race car. It was commissioned by Saudi businessman Mansour Ojjeh, a key figure in TAG Group, which later played a role in Porsche’s Formula 1 engine development. Though Porsche never publicly revealed the price, it is believed Ojjeh paid the equivalent of three brand-new 911 Turbos for this custom creation.
Sprenger’s ability to bring bold concepts to life helped Porsche develop a reputation for delivering bespoke, high-performance vehicles tailored to the individual preferences of discerning customers.
Legacy and Continued Influence
Even after retiring from Porsche, Rolf Sprenger remained an integral part of the brand’s heritage. His expertise in vintage models made him a sought-after consultant for restoration projects. Porsche frequently relied on his knowledge when restoring classic models, ensuring historical accuracy and mechanical precision.
Sprenger’s connection to the Porsche family remained strong throughout his life. He continued to attend prestigious Porsche events, such as the Strähle Swap Meet, the Porsche Rennsport Reunion, and the Porsche Race Car Classic, which was organized by the late Steve Heinrichs. Sprenger and Heinrichs also collaborated on The Porsche Carrera Bible, a definitive work detailing the history and evolution of the Carrera models.
This Porsche archive collaborated with two outstanding authors to document the history of this legendary racing engine and its cars. Rolf Sprenger, a Porsche employee for 40 years, provides an in-depth explanation of the technological evolution of the "Fuhrmann engine," which was in use from 1953 to 1965. His insights ensure that both enthusiasts and experts can appreciate its remarkable engineering sophistication.
