Porsche 911 GT3 Bergsport: A 100-Car Alpine Tribute Built for the Ultimate Mountain Drive

Porsche has never been shy about creating special editions of the 911, but some limited-production models stand apart because of where they can be bought rather than simply how many are built. The new Porsche 911 GT3 Bergsport is one of those rare cars.

Limited to just 100 examples, the Porsche 911 GT3 Bergsport is a geographically restricted special edition developed for customers in Austria, France, Italy and Switzerland. Based on the 911 GT3 Touring, the Bergsport combines the naturally aspirated performance of Porsche’s modern GT3 with styling and equipment inspired by the company’s long association with Alpine hillclimbing.

The new model will make its world premiere at the Arosa ClassicCar event in Switzerland on Thursday, September 3, 2026, an especially appropriate setting given the car’s connection to mountain roads and Porsche’s historic Bergspyder racing cars.

Porsche 911 GT3 Bergsport Brings Alpine Hillclimb Heritage to the Road

The 911 GT3 Bergsport is more than another cosmetic special edition. Porsche has deliberately connected the car to the brand’s history in European hillclimb competition, particularly through the legacy of its lightweight Bergspyder models.

The world premiere at Arosa ClassicCar adds another layer of significance. The event’s 7.2-kilometer course climbs approximately 422 meters, providing a fitting backdrop for a road car inspired by the challenges and character of Alpine driving.

Rather than turning the GT3 into an outright track weapon, Porsche has taken a different approach with the Bergsport. The focus is on the experience of driving a high-performance, naturally aspirated sports car through mountain roads, where precision, engine response and driver involvement matter as much as outright lap times.

Just 100 Porsche 911 GT3 Bergsport Examples Will Be Built

Exclusivity is a major part of the Bergsport’s appeal.

Porsche Exclusive Manufaktur will produce only 100 examples of the 911 GT3 Bergsport. The model is also restricted to four European markets: Austria, France, Italy and Switzerland.

That combination of limited production and geographic availability makes the Bergsport considerably rarer than a conventional 911 GT3. It also reinforces Porsche’s decision to build the car around a very specific theme rather than simply offering another high-performance derivative.

For collectors, the limited production run could ultimately become one of the defining characteristics of the model, particularly because its concept is tied to a recognizable chapter of Porsche motorsport history.

Valleygreenmetallic Gives the 911 GT3 Bergsport a Distinctive Look

One of the most obvious differences between the Bergsport and a standard 911 GT3 is its unique color.

Porsche developed a new shade called Valleygreenmetallic specifically for the series through its Paint to Sample Plus program. The green finish is intended to evoke the Alpine landscape and gives the car an appearance that immediately separates it from more conventional GT3 configurations.

The connection continues inside the cabin.

The 911 GT3 Bergsport features special Valleygreen leather upholstery with decorative stitching inspired by mountain peaks. According to Porsche, this particular design detail is not available on the standard 911 GT3.

That means the Bergsport’s identity isn’t based solely on an exterior paint color. Porsche has carried the Alpine theme throughout the car, giving the limited edition a much more cohesive character.

Porsche 911 GT3 Bergsport Gets a Manual Transmission

While modern performance cars increasingly rely on dual-clutch transmissions and automated gear changes, the Porsche 911 GT3 Bergsport takes a more traditional approach.

The car is equipped with a six-speed manual transmission as part of the Lightweight package.

For a car designed around the enjoyment of Alpine roads, the decision makes sense. Mountain driving is not necessarily about extracting the final tenth of a second from a racetrack. It is about balancing throttle, braking, steering and gear selection through a sequence of corners.

The manual gearbox therefore becomes an important part of the Bergsport’s character, allowing the driver to make full use of the engine’s naturally aspirated power delivery.

Lightweight Package Adds More Than Just Reduced Weight

The Lightweight package also brings forged aluminum wheels, helping reduce mass while supporting the GT3’s focus on sharp handling.

The specification is complemented by a front-axle lift system, an important addition for a car intended to spend time on mountain roads. Steep approaches, ramps and tight switchbacks can be challenging for a low-slung sports car, and the lift system provides additional practicality without compromising the car’s fundamental performance character.

Porsche also equips the Bergsport with a 90-liter fuel tank.

That might seem like an unusual feature for a GT3, but it fits perfectly with the concept behind the car. The Bergsport is designed for long days exploring Alpine roads rather than repeated short sessions on a racetrack. Additional fuel capacity means fewer interruptions when covering long distances through the mountains.

Naturally Aspirated 4.0-Liter Flat-Six Produces 509 HP

Under the rear deck, the Porsche 911 GT3 Bergsport retains the naturally aspirated 4.0-liter flat-six engine used by the current 911 GT3.

The engine produces 509 horsepower and 469 Nm of torque, with all of that power sent to the rear wheels.

Those numbers are significant, but Porsche has not attempted to turn the Bergsport into a horsepower contest. Instead, the special edition stays faithful to the philosophy of the naturally aspirated GT3: high-revving performance, immediate throttle response and a direct connection between the driver and the engine.

That philosophy also explains the manual transmission.

Rather than adding more power simply to make the car faster in a straight line, Porsche has concentrated on the elements that make a mountain road enjoyable: a responsive engine, a lightweight specification, rear-wheel drive and direct driver involvement.

911 GT3 Touring Provides the Foundation

The Bergsport is based on the current Porsche 911 GT3 with the Touring package.

That choice is important because the Touring specification places greater emphasis on understated road-going performance than the more overtly track-focused appearance of a conventional GT3 with a large fixed rear wing.

Combined with the Alpine-inspired design, manual transmission and practical equipment such as the front-axle lift and larger fuel tank, the Bergsport becomes a particularly road-oriented interpretation of the GT3 formula.

It is still unmistakably a GT3, but its mission is different.

Porsche Bergsport Is Inspired by the Bergspyder

The name “Bergsport” deliberately points toward Porsche’s history of building lightweight cars for European hillclimb competition.

Porsche’s Bergspyder race cars were created for precisely the kind of environment that inspired this special edition: steep mountain roads, tight corners, rapid elevation changes and the need for exceptional power-to-weight performance.

The new 911 GT3 Bergsport is not a modern race car, however.

It is a road-legal interpretation of that philosophy. Instead of adopting the uncompromising character of a dedicated competition machine, Porsche has translated the idea of Alpine hillclimbing into a car that can be driven on public roads.

That distinction is particularly important when comparing the Bergsport with track-oriented upgrades such as the 911 GT3 equipped with a Manthey package. The Bergsport is less about maximizing circuit performance and more about celebrating the relationship between Porsche, the Alps and enthusiastic road driving.

A Porsche 911 GT3 Designed for the Alps

Porsche describes the 911 GT3 Bergsport as a combination of the technical qualities of the current GT3 and styling influenced by the Alpine region.

In this case, the theme appears to go beyond marketing.

The Valleygreenmetallic paint, mountain-inspired interior stitching, manual transmission, lightweight components, front-axle lift and enlarged fuel tank all contribute to a coherent idea: a high-performance Porsche designed to be enjoyed on the roads for which it was inspired.

The 509-hp naturally aspirated engine is arguably the centerpiece of that philosophy. At a time when turbocharging, electrification and automated transmissions dominate the performance-car landscape, the Bergsport remains committed to a much more traditional recipe.

A high-revving flat-six. Rear-wheel drive. A manual gearbox. Lightweight construction. And a mountain road.

Porsche 911 Challenge Is the New Entry-Level Race Car for Customer Motorsport

Porsche is expanding its customer motorsport lineup with a new race car that brings the company’s legendary 911 GT3 philosophy closer to drivers taking their first serious steps on a racetrack. Called the Porsche 911 Challenge, the new competition car will become Porsche’s entry-level model for one-make racing from the 2027 season.

Unlike the more specialized Porsche 911 Cup introduced in 2025, the new 911 Challenge retains a much stronger connection to the road-going Porsche 911 GT3. It combines production-derived technology with a comprehensive package of motorsport hardware, creating a race car designed to be fast, approachable and relatively easy for newcomers to understand.

The result is a machine positioned between a highly modified track-day car and Porsche’s more sophisticated customer racing models.

Porsche 911 Challenge Completes the 911 Racing Family

The arrival of the Porsche 911 Challenge gives Porsche an unusually coherent customer racing portfolio. From 2027, all four of the company’s GT racing cars will be based on the 911, creating a clear hierarchy within Porsche Motorsport.

The 911 Challenge sits at the bottom of the range as the entry point for customer racing. Above it is the Porsche 911 Cup, followed by the 911 GT4 R and, at the top of the range, the 911 GT3 R.

This structure allows drivers and teams to progress through different levels of competition without leaving the Porsche 911 family.

Porsche describes the Challenge as a modern interpretation of a philosophy that has been part of its customer racing program since the 1960s: providing customers with a race-ready car that comes with the necessary safety equipment, technical documentation, data acquisition and spare-parts support.

A Racing 911 Closely Related to the GT3

One of the defining characteristics of the new Porsche 911 Challenge is how much technology it shares with the production Porsche 911 GT3.

The car uses the high-revving 4.0-liter naturally aspirated flat-six boxer engine derived largely from the road-going GT3. In racing specification, the engine produces 379 kW, equivalent to 515 PS, at 8,500 rpm.

The engine continues to rev to an impressive 9,000 rpm, preserving one of the defining characteristics of the modern GT3: a powertrain that rewards drivers who are willing to explore the upper reaches of its rev range.

Unlike many dedicated racing cars that rely on sequential gearboxes, the 911 Challenge uses a seven-speed Porsche PDK dual-clutch transmission.

That decision is significant because it makes the car more familiar to drivers who have experience with the road-going 911 GT3.

The driver can select either automatic or manual shifting, with gear changes controlled through steering-wheel paddles.

The racing exhaust system also receives a modified rear silencer and retains a catalytic converter. However, because the Challenge is a competition-only vehicle, it does not require a particulate filter.

515 PS and a 9,000-RPM Redline

The naturally aspirated 4.0-liter flat-six remains the centerpiece of the Porsche 911 Challenge.

Its 515 PS output is not the headline figure by modern turbocharged sports-car standards, but Porsche’s approach is less about maximum horsepower and more about delivering a predictable, high-revving powertrain that can be exploited by drivers of varying experience levels.

The 9,000-rpm redline is particularly important. It gives the Challenge the kind of engine character that has become closely associated with Porsche’s GT3 models.

Rather than overwhelming a novice with extreme power, the 911 Challenge is intended to provide a progressive driving experience in which throttle application, braking and cornering technique remain central to lap-time performance.

Production-Based Technology Makes the Challenge More Accessible

Porsche has deliberately retained several systems from the road-going GT3 to make the transition into customer motorsport less intimidating.

The 911 Challenge features adjustable driver assistance systems including:

  • ABS
  • Traction control
  • Electronic Stability Control
  • Variable driving dynamics systems
  • Multi-stage Porsche Torque Vectoring Plus

The adjustable nature of these systems is particularly useful for racing schools and developing drivers.

A newcomer can begin with more electronic assistance and gradually reduce intervention as their skills and confidence improve. Experienced drivers, meanwhile, can tailor the car to suit track conditions, tire characteristics and driving style.

This makes the Porsche 911 Challenge fundamentally different from a stripped-down race car that expects the driver to understand every aspect of vehicle dynamics immediately.

Porsche 911 Challenge Gets Serious Racing Hardware

Although the Challenge uses significant production-based technology, Porsche has not compromised on its chassis specification.

The suspension incorporates motorsport-specific components, including shock absorbers with racing-specific characteristics and a three-position adjustable anti-roll bar.

The car runs treadless racing slicks mounted on 18-inch wheels. Porsche has also retained a five-hole wheel mounting pattern, following the approach used by the recently introduced 911 GT4 R.

The braking system is equally serious.

The 911 Challenge uses steel racing brake discs measuring 380 millimeters in diameter at both the front and rear. The brake technology is derived from the Porsche GT4 R, giving the entry-level 911 competition car hardware designed specifically for the demands of circuit racing.

GT3 Dimensions, Race-Car Bodywork

The Porsche 911 Challenge shares the same dimensions as the production GT3, while its major body components also follow the road car.

That gives the Challenge an important advantage for drivers transitioning from a road-going 911 GT3 to the race track.

Visually, however, the transformation into a competition car is unmistakable.

An adjustable rear wing can be mechanically set to four different positions, allowing teams to balance aerodynamic performance according to circuit characteristics.

The bonnet uses integrated quick-release fasteners, while a three-jack air-jack system is standard equipment, making pit-lane servicing significantly faster.

At the rear, a FIA-certified rain light provides an essential safety feature for racing in poor weather conditions.

Inside, the Porsche 911 Challenge Is All Business

The biggest transformation occurs inside the cabin.

Everything that isn’t necessary for racing has been removed. Sound-deadening materials, carpets and conventional interior trim are deleted to reduce weight and create a purpose-built competition environment.

In their place is a welded-in roll cage that increases structural rigidity while providing protection during a collision.

The driver sits in an adjustable racing bucket seat secured by a six-point harness.

A 110-liter FT3 safety fuel tank is also installed, while an onboard fire-extinguishing system provides another essential layer of protection.

There is no attempt to disguise the purpose of the vehicle. The Porsche 911 Challenge is not a road car modified for occasional track use. It is a dedicated competition machine.

Porsche 911 Challenge Has No Road Approval

That distinction is important.

The Porsche 911 Challenge is designed exclusively for circuit competition and does not have road approval. Porsche has therefore been able to remove many of the compromises required by a road-legal vehicle.

The result is a machine optimized for racing rather than commuting, touring or weekend road trips.

For customers, that means the Challenge can focus entirely on performance, safety, reliability and ease of operation at the circuit.

Designed for One-Make Porsche Racing

The new Porsche 911 Challenge will make its competitive debut from the 2027 season and is intended for use in numerous Porsche one-make racing series around the world.

Its primary home will be Porsche-branded championships such as the Porsche Challenges and Trophies.

That makes the car particularly relevant to drivers who want to enter organized motorsport without immediately committing to the expense and complexity of international GT competition.

Porsche is effectively creating a progression system within its customer racing ecosystem.

A driver can begin with the 911 Challenge, develop racing experience and eventually move into the 911 Cup, GT4 or GT3 categories.

How the Porsche Customer Racing Range Fits Together

Porsche’s customer racing lineup now covers a broad range of competition levels.

Porsche 911 Challenge

The entry-level model is aimed at racing newcomers and experienced amateur competitors. Its production-based technology and adjustable electronic systems are intended to make it easier to learn and develop as a racing driver.

Porsche 911 Cup

The 911 Cup occupies the next level and competes in the Porsche Mobil 1 Supercup, Carrera Cup championships and other Porsche one-make series. It is also used in endurance and open GT competition.

Porsche 911 GT4 R

The GT4 R is intended for international GT4 competition, one of the fastest-growing segments of global customer motorsport. It represents a significant step toward professional GT racing.

Porsche 911 GT3 R

At the top of Porsche’s customer racing hierarchy sits the 911 GT3 R, developed for international GT3 competition under FIA regulations.

The GT3 R has already established an impressive record, including class victories at Le Mans, World Endurance Championship success and titles in the DTM.

Its résumé was strengthened further with an overall victory at the 24 Hours of Spa-Francorchamps in June 2026.

Porsche Wants More Drivers to Experience Motorsport

The philosophy behind the 911 Challenge is perhaps more important than its technical specification.

Thomas Laudenbach, Vice President of Porsche Motorsport, describes the GT3 models as central to Porsche’s identity as a sports-car manufacturer and emphasizes their close connection to motorsport.

The Challenge expands that relationship by allowing a broader group of customers to experience a Porsche racing car.

Michael Dreiser, Head of Sales at Porsche Motorsport, highlights another advantage: the Challenge delivers the driving experience of the road-legal 911 GT3 in a customer racing environment while reducing the learning curve for new drivers.

That could prove to be one of the car’s greatest strengths.

A New Gateway Into Porsche Motorsport

For decades, Porsche has built a reputation for producing customer racing cars that are competitive without being inaccessible.

The Porsche 911 Challenge continues that tradition in a modern form.

Its combination of a naturally aspirated 515-PS flat-six, seven-speed PDK transmission, production-derived GT3 technology, adjustable electronic systems, racing suspension, slick tires and comprehensive safety equipment makes it an intriguing proposition for amateur racers.

More importantly, it gives Porsche customers a clear entry point into organized motorsport.

The 911 Challenge does not attempt to be the fastest Porsche racing car. Instead, it is designed to be the Porsche racing car that makes the most sense for drivers who are ready to take their first serious step onto the grid.

And that could make it one of the most important additions to Porsche Motorsport’s customer racing portfolio in years.

Porsche Flachbau RS

Porsche has revealed one of its most extraordinary modern one-off creations: the Porsche Flachbau RS, a radically transformed 911 GT2 RS developed through the brand’s exclusive Sonderwunsch programme in collaboration with Manthey.

Based on a virtually new 2018 Porsche 911 GT2 RS Type 991.2 with the Weissach Package, the Flachbau RS combines the brutal performance of Porsche’s most extreme 991-generation 911 with a dramatically redesigned body inspired by the legendary Porsche 935/78 Le Mans racing car, famously known as “Moby Dick.”

The result is a road-legal collector’s car that looks unlike any standard 911 GT2 RS.

The project took almost three years to complete and involved specialists from Porsche Sonderwunsch, Style Porsche, Porsche Motorsport, Weissach development and Manthey. Despite the extensive transformation, the original powertrain was retained.

More importantly, Porsche says the finished car is 31.6 kilograms lighter than the already highly weight-optimised 911 GT2 RS Weissach.

The Flachbau Returns to Porsche

The name Flachbau has a special place in Porsche history.

Also known as “slantnose”, the Flachbau design first became famous in the 1980s when Porsche offered a heavily modified version of the 911 Turbo Type 930. Instead of the traditional 911 front end, the car featured dramatically reshaped front wings and pop-up headlights.

The design was heavily influenced by Porsche’s successful 935 racing cars.

Between 1982 and 1989, Porsche sold 948 examples of the modified 911 Turbo. Even when later conversions are considered, genuine Flachbau models remain among the rarest versions of the classic 911.

That history makes the new Flachbau RS particularly significant.

Porsche had already fuelled speculation in May 2025 when it registered the names “Flachbau” and “Flachbau RS” with the European Patent Office. The reason for those registrations has now become clear.

They were connected to this remarkable factory one-off.

A Modern Interpretation of the Porsche 935 Moby Dick

The design responsibility for the Flachbau RS was given to Grant Larson, the Porsche designer who has since retired.

That choice was particularly appropriate because Larson was also responsible for the modern Porsche 935 unveiled in 2018 to celebrate the 70th anniversary of the legendary racing car.

For the Flachbau RS, the goal was not simply to recreate the 935/78.

Instead, Porsche wanted to reinterpret its most recognizable design elements for a modern road-going 911.

The result is an aggressive front end with significantly lower front wings, new aerodynamic openings and an unusual headlight arrangement that immediately separates the Flachbau RS from the standard GT2 RS.

The inspiration from the famous “Moby Dick” is especially visible in the U-shaped graphic on the bonnet.

Grand Prix White Meets Exposed Carbon Fibre

The Flachbau RS is finished in Grand Prix White, one of Porsche’s most iconic colours.

The shade was specially developed for this particular car, with Porsche using a historic Grand Prix White 911 from its own collection as the colour reference.

The white bodywork is contrasted with matt black elements and exposed carbon fibre.

One of the most distinctive features is the bonnet and roof graphics. Unlike the standard GT2 RS design, the stripes have been inverted, creating a strong visual contrast.

A central stripe and the U-shaped element are made from black exposed carbon fibre and surrounded by Grand Prix White.

The rear-wheel aerodiscs are also painted white, while the brake calipers are finished in deep black.

It is a colour combination that deliberately mixes Porsche’s racing heritage with the technical appearance of a modern GT car.

The Most Important Change Is at the Front

The defining feature of the Porsche Flachbau RS is, of course, its new front end.

The front wings are considerably lower and feature slatted air outlets designed to vent the wheel arches and reduce air pressure.

Because the new bodywork changes the shape of the front wings, Porsche also had to modify the fuel filler flap and its underlying mechanism.

The front bumper was completely redesigned as well.

Small black aerodynamic flaps developed with Manthey add another layer of visual aggression while contributing to the car’s aerodynamic performance.

But perhaps the most fascinating part of the redesign is the lighting system.

Instead of the conventional round headlights of the 911 GT2 RS, the Flachbau RS uses three slim LED elements arranged vertically.

The high beam, low beam and daytime running light are stacked above one another.

The low- and high-beam units are each less than four centimetres tall, while the daytime running light is less than two centimetres high.

The result is a distinctive face that combines the low-slung appearance of the original Flachbau with modern LED technology.

A New Rear Wing Inspired by the 911 GT3 R Rennsport

The front of the car may be inspired by the 935, but the rear wing comes from another part of Porsche’s motorsport world.

The massive rear wing features S-shaped supports inspired by the Porsche 911 GT3 R Rennsport Type 992.

On the Flachbau RS, however, the wing sits approximately five centimetres higher.

The wing can be manually adjusted into three different positions, allowing the driver to alter the aerodynamic balance depending on the intended use.

According to Porsche, the aerodynamic performance is improved compared with a 911 GT2 RS equipped with the Manthey Kit and using the corresponding wing settings.

At 340 km/h in the High Downforce setting, the Flachbau RS generates exactly 554 kg of downforce on the rear axle.

The wing adjustment mechanism and position markings are also protected by patent.

Manthey Aerodynamics Take the GT2 RS Even Further

The Flachbau RS is more than a visual exercise.

Manthey’s aerodynamic expertise plays a major role in the car’s transformation.

A redesigned front splitter works together with the underbody components and rear diffuser from the Manthey Kit to improve aerodynamic performance.

At the rear, carbon-fibre aerodiscs reduce aerodynamic drag while maintaining the aggressive motorsport-inspired appearance.

The combination of the new bodywork, underbody aerodynamics and large rear wing gives the Flachbau RS a substantially different aerodynamic character from a standard 911 GT2 RS.

And Porsche did not simply install the parts and send the car to its owner.

The entire package went through an extensive engineering and validation programme.

Nearly 32 Kilograms Lighter Than the GT2 RS Weissach

Weight reduction was another major objective.

That is especially impressive because the starting point was already a 911 GT2 RS with the Weissach Package, a car designed from the beginning to minimise weight.

Nevertheless, Porsche managed to remove 31.6 kg from the vehicle.

A significant part of the weight reduction came from the interior.

The Porsche Communication Management system was removed and replaced by a leather-trimmed storage compartment.

The audio system was deleted, while sound insulation, carpeting and other interior materials were substantially reduced or removed.

The rear section of the cabin has been transformed into something much closer to a racing car.

Instead of a conventional finished interior, various components are exposed and painted in Grand Prix White.

Carbon-fibre trim is used selectively, while parts of the newly arranged wiring harness remain visible beneath protective sheathing.

Even unnecessary wiring was removed in the pursuit of weight savings.

A Racing Interior for a Road-Legal Car

The front section of the cabin retains much of the original red Alcantara, black leather and exposed-carbon look of the GT2 RS.

Behind the seats, however, the philosophy changes dramatically.

The interior becomes deliberately spartan.

The carbon-fibre bucket seats feature “Flachbau RS” embroidery, with a stylised outline of the Nürburgring Nordschleife positioned behind the lettering.

On the passenger side of the dashboard sits a gold-coloured Sonderwunsch badge.

A dedicated plaque carries the inscription:

“Factory One-Off 2026 | Flachbau RS”

Even mandatory road-car equipment has been reconsidered.

The conventional mounting points for items such as the warning triangle and towing eye were removed. Instead, these components are stored in a removable emergency box.

When the car is used on a circuit, the box can be taken out to save additional weight.

Porsche Had to Prove the Flachbau RS Was Safe

Creating a one-off body for a high-performance road car is considerably more complicated than simply designing new panels.

Porsche carried out extensive digital validation before approving production.

The engineering process included simplified crash simulations, airbag deployment validation and detailed structural analysis.

One of the most important areas of investigation was the enormous rear wing and the forces it generates at high speed.

Porsche also used Computational Fluid Dynamics (CFD) to analyse and optimise the car’s aerodynamic characteristics.

Only after the virtual validation process had been completed did Porsche approve the production of new tooling for the redesigned components.

Three Test Cars and 50 Nürburgring Laps

The validation process continued with physical testing.

The new rear wing was subjected to extreme vibrations on a hydropulse test rig designed to simulate the stresses experienced during road use.

Its static load capacity was also tested using sandbags.

Porsche ultimately built three test vehicles for the development programme.

These cars underwent lighting and wind-tunnel testing, real-world road testing and extensive durability testing.

Testing included numerous runs at Mendig airfield, endurance work at Porsche’s Weissach facility and 50 laps of the Nürburgring-Nordschleife.

In total, Porsche says the testing simulated a load on the rear wing equivalent to approximately 150,000 kilometres of customer use.

That level of testing illustrates how seriously Porsche approached the transformation.

The Flachbau RS may be a single road-legal collector’s car, but Porsche wanted it to meet the company’s standards for safety, durability and performance.

Tested by Lars Kern at the Nürburgring

Porsche test driver Lars Kern was among those responsible for evaluating the finished car on the Nürburgring.

The Nordschleife is particularly useful for assessing aerodynamic stability because of its combination of high-speed sections, elevation changes and complex corners.

According to Kern, the Flachbau RS remained stable and precise even at extremely high speeds.

That is an important achievement considering how extensively the original GT2 RS bodywork was modified.

The testing was not simply about proving that the car could survive.

It was about making sure that the new aerodynamic concept behaved predictably at the limit.

The Prototype That Became an Internet Sensation

Before Porsche officially revealed the Flachbau RS, the project had already attracted attention.

A camouflaged slantnose prototype was spotted testing at the Nürburgring, where videos quickly appeared on social media.

Those videos reportedly generated more than 100,000 views within just a few hours.

For Porsche enthusiasts, the unusual silhouette was immediately intriguing.

A modern 911 GT2 RS with a dramatically reshaped front end was clearly something different, and the appearance of the prototype only intensified speculation surrounding the Flachbau and Flachbau RS trademarks.

Now the mystery has been solved.

A 911 GT2 RS Unlike Any Other

The Porsche Flachbau RS is not simply another special-edition 911.

It is a demonstration of what happens when Porsche’s Sonderwunsch programme is given almost unrestricted creative and engineering freedom.

The starting point was already one of the most extreme road-going 911s ever produced: the 991.2-generation GT2 RS with the Weissach Package.

From there, Porsche transformed the car’s identity.

The traditional 911 silhouette was replaced by a modern interpretation of the Flachbau design. The front end pays tribute to the 935/78 Moby Dick, the rear wing draws inspiration from the 911 GT3 R Rennsport, and Manthey’s aerodynamic expertise adds genuine functional performance.

Most importantly, the project retains the spirit of Porsche’s motorsport heritage without turning the car into a mere historical replica.

It is a modern Flachbau for the GT2 RS generation.

And perhaps that is what makes the Porsche Flachbau RS so fascinating: it connects three different eras of Porsche performance in a single machine—the legendary 935 of the late 1970s, the iconic Flachbau 911 Turbo of the 1980s, and the brutally fast 991.2 GT2 RS of the modern era.

For collectors, it represents something even more valuable.

There is only one.
