Overview
RUF Automobile GmbH is a German specialist sports-car manufacturer based in Pfaffenhausen, Bavaria. The company began in 1939 as Auto Ruf, a service garage established by Alois Ruf Sr., and gradually developed from automotive repair into a broader engineering and manufacturing business. Although RUF became closely associated with Porsche-based performance cars, it is legally recognized in Germany as a vehicle manufacturer rather than merely a tuning workshop. Its independently assigned vehicle identification numbers, proprietary engineering, and later use of in-house bodies and chassis distinguish its products from ordinary modified Porsches. The company’s early development included the expansion of the original garage into a full-service filling station in 1949. Alois Ruf Sr. also experimented with vehicle design and built a tour bus in 1955, later establishing a separate bus business after the project attracted commercial interest. His son, Alois Ruf Jr., developed a strong interest in sports cars and began servicing and restoring Porsche automobiles at the family business in 1960. After his father’s death in 1974, the younger Ruf assumed control at the age of 24 and redirected the company toward high-performance Porsche 911 engineering. RUF produced its first enhanced Porsche in 1975 and introduced its first complete model in 1977, based on the Porsche 911 Turbo but equipped with a larger 3.3-liter engine. The 1978 SCR followed as a naturally aspirated, 3.2-liter 911-based model. These projects established the company’s characteristic combination of discreet styling, substantial power, handcrafted construction, and detailed chassis and drivetrain development. RUF achieved international recognition with the 1987 CTR, commonly associated with the nickname “Yellowbird.” During high-speed testing in 1987, the car reached 339 km/h, exceeding the claimed top speed of the Ferrari F40 and making the CTR one of the defining performance cars of its era. The later CTR2 extended the concept in the 1990s, reaching a reported 350 km/h and briefly occupying the top tier of road-legal production cars before the McLaren F1 surpassed it. The company subsequently expanded beyond Porsche-derived architecture. Introduced in 2007, the CTR3 was developed with Canadian engineering firm Multimatic and used a mid-mounted engine, a dedicated chassis, and an original body. It was presented in connection with the opening of RUF’s Bahrain facility and the twentieth anniversary of the original CTR. In 2017, RUF unveiled the CTR Anniversary, its second major model with a wholly proprietary body and chassis. While its proportions recalled the 911, the car used very few Porsche components and featured a RUF-specified powertrain and transmission. The 2018 SCR adopted the same general in-house platform with a naturally aspirated engine. RUF’s business today spans complete sports cars, restoration and conversion work, and performance components for Porsche models including the 911, Boxster, and Cayman. Its limited-production vehicles target collectors, driving enthusiasts, and customers seeking bespoke engineering rather than mass-market volume. RUF has also explored alternative propulsion, most notably through the eRUF Model A and eRUF Greenster programs. Outside the physical automobile market, the brand gained broad visibility through racing video games, where RUF models were often used as alternatives to Porsche vehicles during periods of exclusive Porsche licensing. The company remains defined by low-volume craftsmanship, extreme performance, and technical independence from Porsche.
History
RUF Automobile traces its origins to 1939, when Alois Ruf Sr. established Auto Ruf as an automotive service garage in Pfaffenhausen, Germany. The business expanded into a full-service filling station in 1949. Ruf Sr. was not limited to repair work: during the late 1940s he experimented with vehicle concepts, and in 1955 he designed and built a tour bus. The favorable response to that project led him to create a separately operated bus company, giving the family an early connection with vehicle design and manufacturing. Alois Ruf Jr. grew up around the business and developed a particular interest in sports cars. Beginning in 1960, he serviced and restored Porsche automobiles from his father’s premises, with the Porsche 911 eventually becoming the central focus of his professional work. When Alois Ruf Sr. died in 1974, his 24-year-old son took over the company. Under the younger Ruf’s direction, the business moved away from being primarily a general repair operation and concentrated on engineering faster, more capable versions of Porsche sports cars. The first RUF-enhanced Porsche was completed in 1975. In 1977, the company introduced its first complete model, a 911 Turbo-based car with a modified 3.3-liter engine. A naturally aspirated model called the SCR followed in 1978, using a stroked 3.2-liter engine and attracting substantial customer interest. These cars established RUF’s reputation for combining Porsche foundations with its own powertrain development, gearing, suspension work, body modifications, and assembly standards. The decisive breakthrough came with the 1987 CTR. Its high-speed testing result of 339 km/h, and a later reported run of 342 km/h in 1988, made it internationally famous. The CTR exceeded the claimed top speed of the Ferrari F40 and became an icon of the emerging supercar performance era. RUF followed it with the CTR2 in 1995. With a reported top speed of approximately 350 km/h, the CTR2 briefly ranked among the fastest road-legal production cars before the McLaren F1 took the title later in the decade. The CTR2’s performance was notable not only for its speed but also because its price was substantially below that of the McLaren. RUF continued to evolve from a Porsche specialist into an independent manufacturer. The CTR3, revealed in 2007, was developed with Multimatic and used a mid-engine layout, an original body, and a dedicated chassis. This architecture separated it technically from the rear-engine 911 format and demonstrated that RUF could create a distinct supercar rather than only modify an existing Porsche shell. At the 2017 Geneva Motor Show, RUF presented the CTR Anniversary. Developed with Vela Performance, it used a RUF-designed body and chassis and incorporated very limited Porsche-sourced components. Its 3.6-liter twin-turbocharged flat-six and RUF-specified seven-speed transmission reinforced the company’s independent engineering identity. The following year, RUF showed the new SCR, a naturally aspirated model using the same broad proprietary platform and reviving the name of the 1978 car. Alongside combustion-engine sports cars, RUF explored electrification through the eRUF Model A, which used an electric propulsion system and lithium-ion batteries, and the later eRUF Greenster concept. The company also manufactures performance parts for Porsche models and has maintained a significant cultural presence in racing games. During periods when Porsche licensing was exclusive to particular publishers, RUF’s status as a recognized manufacturer allowed game developers to include RUF vehicles as distinct marques. RUF remains a low-volume, specialist manufacturer whose identity rests on hand-built construction, extreme road-car performance, and technical autonomy.

High-performance sports car · 1987
RUF CTR
The 1987 CTR, widely nicknamed Yellowbird, was a heavily engineered 911-derived performance car. Its combination of low weight, turbocharged power, revised aerodynamics, and RUF-developed running gear enabled a landmark 339 km/h test speed. The car became the defining symbol of RUF’s engineering reputation and remains one of the most recognizable German supercars of the 1980s.
High-performance sports car · 1995
RUF CTR2
Introduced in the mid-1990s, the CTR2 developed the original CTR formula for a later generation of Porsche-based performance engineering. It achieved a reported top speed of approximately 350 km/h, placing it briefly among the world’s fastest road-legal production cars. Its performance demonstrated that RUF could compete with far more expensive contemporary supercars while retaining a relatively discreet visual identity.
Mid-engine supercar · 2007
RUF CTR3
The CTR3 was developed with Multimatic and represented a major technical departure from RUF’s traditional rear-engine, 911-derived format. It used a mid-mounted engine, a dedicated chassis, and an original body designed to evoke the visual language of the 911 without being a conventional Porsche conversion. The model established RUF as a constructor of independently engineered supercars.

RUF SCR
The 2018 SCR is a modern naturally aspirated sports car built on the general in-house body and chassis architecture introduced with the CTR Anniversary. It revives the name of RUF’s 1978 SCR while pursuing a different character from the turbocharged CTR: linear engine response, high-revving performance, and a more traditional driver-focused experience. The model illustrates RUF’s ability to reinterpret its historical nomenclature through proprietary engineering.
Electric sports-car prototype
eRUF Model A
The eRUF Model A was an electric sports-car program using a UQM electric propulsion system and lithium-ion batteries. RUF stated performance targets including a 225 km/h top speed, 150 kW of power, and an estimated range varying with driving conditions. The proposed production schedule did not proceed as initially announced, but the project represented an early exploration of battery-electric performance vehicles by a specialist manufacturer.
Electric sports-car concept · 2009
eRUF Greenster
The eRUF Greenster was presented as a subsequent electric performance-car concept after the Model A program. RUF announced limited-production intentions at the 2009 Geneva Motor Show, positioning the vehicle as an environmentally oriented interpretation of the company’s sports-car philosophy. Publicly available reference material does not establish that series production occurred.
