Alois Ruf Jr. (2010)

Key Information

Ruf Automobile GmbH (stylized as RUF) is a German car manufacturer. Formerly using Porsche bodies in white to build cars, today they build vehicles on their own bodies and chassis. They also manufacture performance parts for various Porsche models, including the 911, Boxster, and Cayman.

The company rose to fame when in 1987, its Porsche-derived CTR reached 339 km/h (211 mph), surpassing the Ferrari F40's claimed top speed of 321 km/h (199 mph).

History

[edit]

The company was founded in 1939 in Pfaffenhausen, Germany as "Auto Ruf" by Alois Ruf Sr. as a service garage and was eventually expanded to include a full-service gas station in 1949. Ruf began experimenting with vehicle designs of his own in the late 1940s, and in 1955 designed and built a tour bus, which he marketed around Germany. The positive response it received led to Ruf expanding his business again by starting his own separately owned bus company.

Alois Sr.'s involvement in the car industry had a distinct effect on his son, Alois Ruf Jr., who became a sports car enthusiast. In 1960, Alois Jr. began servicing and restoring Porsche automobiles out of his father's garage. Following Alois Sr's. death in 1974, 24-year-old Alois Jr. took control of the business and focused on his passion: Porsche vehicles, and especially the 911. A year later in 1975, the first Ruf-enhanced Porsche came to life.

Ruf debuted their first complete model in 1977, a tuned version of Porsche's 911 Turbo with a stroked, 3.3-litre motor. This was followed in 1978 by Ruf's first complete non-turbo Porsche, the 911 SCR. It was a naturally aspirated 911 with a stroked 3.2-litre motor producing 217 horsepower. Numerous customer orders were placed for this vehicle.[1]

In 1987, Ruf released the Ruf CTR, which achieved a top speed of 339 km/h (211 mph) in April 1987 and set the record as the world's fastest production car for its time; in 1988 it even reached 342 km/h (213 mph). Its successor, the 1995 Ruf CTR2, had clocked a top speed of 350 km/h (217 mph), making it for a brief moment the fastest road-legal production car in the world in the mid '90s, until the McLaren F1 broke the record in 1998 at 241 mph, thus making the CTR2 the second-fastest production car of the decade. However, the CTR2 cost only a fraction of the price of the F1.[2][3][4]

In April 2007, Ruf released the new CTR3 to celebrate the company's new plant in Bahrain, and as a 20th anniversary celebration of the original CTR and successor to the CTR2. The Ruf CTR3 was designed and engineered in a partnership with the Canadian engineering firm Multimatic.[5] The Ruf CTR3 was Ruf's first entirely unique model, built using their own chassis and body. The CTR3 differs from typical Ruf models in that it uses a Mid-engine design, as opposed to the 911's Rear-engine design. Automotive journalists have compared it to the Porsche 911 GT1, which similarly used a mid-engine layout with a body designed to resemble the Porsche 911.[6]

In 2017, Ruf unveiled the Ruf CTR Anniversary at the Geneva Motor Show, 30 years after the launch of the original Ruf CTR. The CTR Anniversary is Ruf's second model to use their own body and chassis design, which was designed and engineered in partnership with German engineering firm Vela Performance. The Ruf CTR Anniversary retains the Porsche 911's rear-engine layout, but does not use any major Porsche components. The only original Porsche parts are windows and windscreen wipers borrowed from the 964 and 993.[7] The CTR Anniversary uses a 3.6-litre water cooled twin-turbocharged flat-6 engine producing 700 hp (710 PS; 522 kW), and a custom 7-speed transmission built to Ruf's specification by ZF,[8] and is unrelated to any Porsche transmissions.

In 2018, Ruf unveiled the new Ruf SCR. The SCR uses the same in-house body and chassis design from the Ruf CTR Anniversary, although with a normally aspirated engine producing 510 PS (503 hp; 375 kW). The 2018 Ruf SCR borrows its name from the 1978 Ruf SCR.

Main article: eRuf Model A

The eRuf Model A is an all-electric sports car made by Ruf Automobile. The car is powered by a UQM Technologies[15] propulsion system (a UQM PowerPhase 150). The car has a top speed of 225 km/h (140 mph)[16] and is capable of producing 150 kW (204 PS; 201 hp) and 649 N⋅m (479 lb⋅ft) of torque.[17] Estimated range per charge is 250–320 km (155–199 mi), depending on performance level, using iron-phosphate, lithium-ion batteries built by Axeon of Great Britain.[18] The power and torque produced by the 3-phase motor can be used to recover almost as much power as it can put out. During coasting the engine works as a generator producing electricity to charge the batteries.[19] Ruf announced that it hoped to begin production of the eRuf in the autumn of 2009.[20] This did not happen, and at the 2009 Geneva Motor Show, Ruf announced a new model, the eRUF Greenster, with limited production planned to commence at the end of 2010.[21]

In video games

[edit]

Ruf models have historically appeared in many large racing video game franchises as a substitute for the Porsche models they are based on due to Porsche's exclusive licensing in video games.[22] Starting with the release of Need for Speed: Porsche Unleashed in 2000, Porsche entered an exclusivity deal with Electronic Arts (EA) which meant that Porsche models would only appear in EA's titles, most notably the Need for Speed franchise and the Real Racing series. The only exceptions to this were a number of games in the Forza and Project Gotham Racing series due to sub licensing arrangements made between EA and their games' respective developers, Turn 10 Studios and Bizarre Creations. Other large video game franchises, however, including Gran Turismo, Project CARS, Assetto Corsa, Asphalt, Test Drive, The Crew, Driver: San Francisco, Driveclub and a few Forza games used Ruf models in place of Porsche. This circumvented Porsche's licensing as Ruf is considered by the German government to be a full-fledged manufacturer, and as such Ruf models have unique VINs.[23] The exclusivity deal between Porsche and EA ended in 2016, leading many franchises to stop featuring Ruf models in favor of Porsche.[24] Though it has never been publicly confirmed, it has been speculated that Porsche and RUF can no longer co-exist in games due to interference from Porsche. For instance, in Asphalt 8: Airborne, RUFs and all other vehicles resembling Porsches became unobtainable for purchase in a Porsche-themed update, but users who had them before the update kept them, until an update in 2023 The Crew 2 features both brands, but neither competes against each other due to the game's car classification system. However, Gran Turismo Sport, Gran Turismo 7, Gear.Club Unlimited 2, a few Forza titles and Nitro Nation feature both brands that can compete against each other at any time.

Building on the Model A, the Stormster debuted in 2009 as Ruf's electric take on the platform, targeting urban luxury with all-wheel-drive capability. Equipped with a electric motor delivering 270 kW (367 hp) and all-wheel distribution, it achieved 0-100 km/h in about 10 seconds despite its 2,670 kg weight, with a top speed limited to 150 km/h for efficiency. The vehicle used a Li-Tec ceramic-separator pack, providing a 200 km range and supporting a full charge in one hour via 400V supply, underscoring Ruf's aim for practical electric SUVs. That same year, at the Motor Show, Ruf presented the Greenster, a variant evolving from the Model A on the Targa chassis, conceptualized as an open-top electric . It incorporated a motor tuned to 270 kW (367 hp) and 950 Nm of torque, achieving 0-100 km/h in approximately 4.9 seconds (0-60 mph) and a 250 km range with its lithium-ion batteries. While early Greenster iterations drew from internal combustion tuning expertise for chassis refinement, the eRuf version prioritized electric propulsion to blend performance with emissions-free operation. Central to these developments was Ruf's partnership with UQM Technologies for the Model A's propulsion system, later expanding to Siemens for higher-output applications in the Stormster and Greenster. Engineers emphasized lightweight materials like carbon fiber components to mitigate battery mass—totaling around 1,500-1,700 kg for the sports car prototypes—ensuring agile handling despite added weight. However, all eRuf concepts remained limited to prototypes, with no series production pursued due to the nascent state of battery technology, which constrained range and charging infrastructure in the late .

Evolution and Current Status

Following the unveiling of early eRuf concepts in the late 2000s, Ruf Automobile entered a hiatus in its electric vehicle development, with no series production of fully electric models materializing after 2009 due to the immature state of the EV market and a strategic pivot toward high-performance internal combustion engine (ICE) vehicles. Prototypes from this era were retained for research and development purposes, informing later engineering insights without leading to commercialization. Throughout the and , Ruf pursued no full electric vehicles, instead conducting limited testing with electrified prototypes in 2011 to evaluate high-performance EV applications, while emphasizing efficient technologies such as the emissions-compliant in the 2025 model. This period saw Ruf's resources directed toward thermodynamic powertrains, aligning with client demand for traditional driving experiences over electrification. As of 2025, Ruf maintains no active electric models in production, prioritizing through alternative means like support for synthetic fuels over battery-electric systems, as articulated by CEO Alois Ruf, who described past EV efforts as "just an idea" and affirmed the company's commitment to "stay[ing] thermodynamic" to preserve driving purity. While Ruf incorporates carbon fiber in and body components for models like the SCR and to reduce weight and enhance performance, there is no emphasis on recycled materials in public disclosures. Looking ahead, any potential revival of Ruf's EV program remains unconfirmed and tied loosely to ongoing Porsche collaborations, though Ruf's leadership has expressed skepticism about battery scalability without breakthroughs in sustainable sourcing. This stance contrasts with growing collector enthusiasm for rare Ruf vehicles, including early prototypes, amid skyrocketing auction values for the brand's limited-edition ICE models. Ruf's electric endeavors have faced persistent challenges, including high battery costs, limited range under demanding conditions—such as failing to reach on the during prototype testing—and performance trade-offs from added weight that compromise the agile handling central to the brand's identity. These factors have reinforced Ruf's focus on ICE innovation to meet modern emissions standards without sacrificing core engineering principles.

Cultural Impact

Media and Video Games

Ruf Automobile has gained significant cultural visibility through its appearances in media, particularly via the iconic 1987 promotional video "Faszination," featuring test driver Stefan Roser piloting the CTR Yellowbird around the Nordschleife. Originally produced as an internal company presentation, the roughly 20-minute film captured the car's dynamic handling and speed in a raw, unscripted style that resonated widely, earning acclaim as one of the earliest viral automotive videos and inspiring subsequent segments on shows like Top Gear as well as automotive documentaries. By 2025, various uploads of the footage had collectively amassed millions of views, underscoring its enduring influence on car enthusiast culture. Documentaries have further highlighted Ruf's history and engineering prowess. In 2020, Kahn Media released "RUF: Love at the Red Line," a tracing the company's evolution from a Porsche service garage to a manufacturer, with heavy emphasis on the Yellowbird's legacy; it was promoted through platforms like Hagerty Media. An earlier 2015 documentary, "Porsche Ruf Faszination," provided an in-depth look at Ruf's operations and vehicle development. More recently, in 2025, interviews with CEO Alois Ruf appeared on Motor1, discussing the company's innovations and future directions, while channels like Big Car Channel and The Smokin' Tire featured extended conversations on Ruf's family-run ethos and iconic models. Ruf vehicles have been prominently featured in video games, often serving as high-performance stand-ins for Porsche models due to licensing arrangements. The Gran Turismo series included Ruf cars starting with Gran Turismo 2 in 1999, with the CTR Yellowbird appearing as a top-tier vehicle across multiple entries, including Gran Turismo 6. In the Forza Motorsport franchise, Ruf debuted in Forza Motorsport 4 (2011) with exclusive DLC packs, continuing in subsequent titles like Forza Horizon 2, which helped elevate brand recognition among gamers. Need for Speed games incorporated tunable Ruf-based 911 variants during periods of Porsche exclusivity deals with Electronic Arts. By 2025, Ruf models had appeared in over 20 racing titles, including Project CARS, Assetto Corsa, Asphalt, Test Drive, The Crew, and Driver: San Francisco, typically positioned as premium unlocks for their superior speed and handling simulations. Beyond documentaries and games, Ruf has appeared in feature films and print media. Tuned Porsche variants with Ruf engineering featured indirectly in the franchise, notably through the in (2015), which utilized a 3.7-liter twin-turbo developed by Ruf. Automotive publications like have covered Ruf extensively, including a 2025 feature on the Tribute model—an air-cooled homage to classic 911s—with Aloisa Ruf demonstrating its twin-turbo at events like The Quail. These media portrayals have notably boosted Ruf's brand awareness, with video game inclusions credited for positive exposure and modest sales upticks in the late 1990s following Gran Turismo releases, as enthusiasts sought real-world equivalents to their digital favorites.

Legacy and Market Presence

Ruf Automobile's legacy as a pioneer in extreme performance tuning dates back to the 1980s, when the company achieved the first production car speed exceeding 300 km/h with the CTR "Yellowbird" in 1987, setting benchmarks that elevated tuning from modification to engineering innovation. This milestone not only outpaced contemporaries like Porsche and Ferrari but also established Ruf as an independent manufacturer, issuing its own VINs since 1981 under German regulatory approval, which solidified its status as an original equipment manufacturer (OEM) rather than a mere tuner. Ruf's approach influenced the broader restomod and high-performance Porsche modification landscape, paving the way for specialists like Singer Vehicle Design, which adopted similar philosophies of bespoke engineering on 911 platforms, though focusing on air-cooled variants. The collectibility of Ruf vehicles has surged in the 2025 market, driven by their rarity and historical significance, with vintage models commanding premium prices at auctions. For instance, a 1989 Ruf CTR "Yellowbird" sold for $6.055 million at Gooding & Company's Amelia Island auction in March 2025, marking the highest price ever for a Ruf at public sale and underscoring values well exceeding €1 million. Similarly, another Yellowbird fetched $4.68 million at Broad Arrow's Air|Water Auction in April 2025, reflecting a broader trend where Ruf-tuned classics appreciate significantly due to limited production—often fewer than 30 units per model—and investor demand for authenticated performance icons. Models like the , one of Ruf's earliest self-VIN'd designs from the late , have seen values climb, with a 1994 estimated at $800,000–$1.2 million for the September 2025 auction but ultimately not sold, highlighting annual appreciation fueled by scarcity and provenance. Newer Ruf models continue this trajectory, with the 2026 —an air-cooled homage to classic 911s—priced at approximately $1.7 million, limited to 50–100 units over five years to maintain exclusivity. Market trends in 2025 show a price surge for vintage Rufs, exemplified by the Yellowbird's 41-fold increase over its original value, as collectors seek alternatives to standard Porsches amid rising classic car investments. Ruf maintains a strong global presence, with the majority of its 30–35 annual production centered in , where its Bavarian in Pfaffenhausen serves as the core hub for engineering and sales. The company has expanded into via its first dedicated import and distribution center in , opened in 2023, which has boosted U.S. through dedicated showrooms, service, and dealer networks, accounting for a growing share of exports. In Asia, Ruf has established outposts in , , and , facilitating increased regional sales and customization, though remains dominant at over 70% of volume based on its home-market focus and regulatory advantages. Despite its enduring appeal, Ruf faces challenges in 2025 from the automotive industry's shift toward , particularly Porsche's evolving , which includes delaying full EV transitions in favor of hybrids while navigating weak demand and trade barriers. As a combustion-engine specialist, Ruf's internal focus—exemplified by synthetic fuel testing at —puts pressure on its niche amid stricter emissions regulations and competition from electric hypercars, though CEO Ruf emphasizes sustainable fuels and small-scale production to sustain viability. An early 2008 EV prototype highlighted battery limitations for high-speed applications, reinforcing Ruf's commitment to thermodynamic engines over full .
