The Ultimate Guide To The Porsche 991: Every Variant, Specs, Reviews, Performance & More
The Porsche 911 (991 generation) was a bold leap into the future for the iconic sports car, blending innovation with heritage in a way that captured the essence of what makes the 911 so revered. Produced between 2011 and 2019, the 991 generation redefined the 911 for the modern age. It was larger, more sophisticated, and packed with new technology, yet it never lost sight of its roots. For many enthusiasts, the 991 struck a near-perfect balance between tradition and progress, offering a driving experience that felt both familiar and revolutionary.
This is the story of how the 991 generation came to be, the models that defined it, and why it remains such an important chapter in the 911’s legacy.
A New Era for the Porsche 911
By the late 2000s, Porsche faced the challenge of taking the 911 to new heights while staying true to its heritage. The 997 generation had been a resounding success, but the automotive world was changing. Competitors were advancing rapidly, and regulations demanded greater efficiency, safety, and technology. Porsche knew the 911 had to evolve, and in 2011, the 991 generation made its debut at the Frankfurt Motor Show.
From the moment it was unveiled, the 991 made a statement. It was longer and wider than its predecessor, but thanks to a new aluminum-steel composite construction, it was lighter and stiffer. The design, led by Michael Mauer, honored the classic 911 silhouette while introducing sharper lines and a more aerodynamic shape. The iconic round headlights remained, but the overall look was sleeker, more modern, and undeniably Porsche.
Beneath the surface, the 991 was a marvel of engineering. The wheelbase was stretched by 100 millimeters, improving stability and interior space. The rear-engine layout—a hallmark of the 911—was refined to enhance handling and balance. Porsche also introduced electric power steering, a controversial change that promised greater efficiency and adaptability, though some purists were skeptical at first.
The 991 was produced in two phases: the 991.1 (2011-2016) and the 991.2 (2016-2019). The 991.2 brought another seismic shift by introducing turbocharging across the Carrera lineup, a move that divided opinions but ultimately delivered more power, torque, and efficiency.
The Regular Models: An Evolution in Performance
The journey through the 991 lineup began with the Carrera, a model that embodied the essence of the 911. The 991.1 Carrera featured a 3.4-liter naturally aspirated flat-six engine, delivering 350 horsepower. The Carrera S, with its larger 3.8-liter engine, produced 400 horsepower. Both models offered the choice of a 7-speed manual transmission or Porsche’s lightning-fast 7-speed PDK dual-clutch gearbox.
With the introduction of the 991.2, Porsche took a bold step by turbocharging the entire Carrera range. The naturally aspirated engines were replaced with 3.0-liter twin-turbo flat-sixes. The base Carrera now produced 370 horsepower, while the Carrera S offered 420 horsepower. The turbocharged engines provided a broader power band and increased efficiency, making the 991.2 models faster and more versatile.
For those who wanted all-weather confidence, the Carrera 4 and Carrera 4S provided the same engines as their rear-wheel-drive counterparts but with Porsche’s sophisticated all-wheel-drive system. The wider rear fenders and a distinctive light strip across the rear gave these models a muscular and unmistakable appearance.
In 2014, the Targa returned to the 911 lineup with the 991 Targa 4 and Targa 4S. These models paid homage to the classic Targas of the past with a modern twist—a beautifully engineered retractable glass roof that stowed itself behind the rear seats. The Targa offered open-air freedom while maintaining the structural rigidity of a coupe.
As the 991 evolved, Porsche introduced the Carrera GTS in 2015. Positioned between the Carrera S and the GT3, the GTS offered 430 horsepower (later 450 horsepower in the 991.2) and a suite of performance upgrades. With its wider body, center-lock wheels, and sportier suspension, the GTS was the ideal 911 for enthusiasts seeking a blend of performance and practicality.
Pushing Boundaries: The Special Models
The 991 generation was defined not just by its regular models but by a series of extraordinary special editions that pushed the boundaries of performance and innovation.
The 991 Turbo and Turbo S were among the fastest and most technologically advanced 911s ever created. The Turbo, introduced in 2013, featured a 3.8-liter twin-turbo flat-six producing 520 horsepower. The Turbo S upped the ante to 560 horsepower (later 580 in the 991.2). With all-wheel drive, active aerodynamics, and blistering acceleration, these cars were capable of 0-60 mph times as low as 2.8 seconds. They were supercar slayers in everyday clothing.
For those who preferred a purer, track-focused experience, the GT3 was a revelation. The 991 GT3, launched in 2013, featured a high-revving 3.8-liter naturally aspirated engine producing 475 horsepower. With rear-wheel steering, a PDK transmission, and a chassis tuned for the track, the GT3 was a precision instrument. In 2015, the GT3 RS took this formula even further, with a 4.0-liter engine producing 500 horsepower, extensive weight-saving measures, and aggressive aerodynamics.
In 2016, Porsche delighted purists with the 911 R—a back-to-basics, limited-edition model that combined the GT3 RS’s 500-horsepower engine with a 6-speed manual gearbox. Just 991 units were produced, making it an instant collector’s item.
The swan song of the 991 generation was the 2019 911 Speedster, a stunning open-top model built to celebrate Porsche’s 70th anniversary. Powered by the GT3’s 4.0-liter engine and featuring a 6-speed manual transmission, the Speedster was limited to just 1,948 units, a nod to Porsche’s founding year.
Why the 991 Generation is Special
The 991 generation holds a unique place in the 911’s storied history. It was a bridge between the past and the future, combining traditional Porsche values with cutting-edge technology. The 991’s lightweight construction, advanced chassis, and turbocharged engines made it one of the most capable and versatile 911s ever built.
The special models—from the blistering Turbo S to the track-ready GT3 and the pure 911 R—showcased Porsche’s commitment to pushing boundaries while honoring its heritage. These cars have become modern legends, celebrated for their engineering, performance, and driving experience.

Mk 1 (991.1) vs Mk 2 (991.2) - Tale of Two Eras
When the Porsche 911 (991) arrived in 2011, it was more than just the next chapter in the 911 story. It was a statement: a car that pushed the boundaries of modern engineering while fiercely holding on to its heritage. Larger, faster, and brimming with technology, the 991 marked a clear departure from its predecessor, the 997. But within the span of eight years, two distinct versions of the 991 emerged: the 991.1 (Mk 1) and the 991.2 (Mk 2).
At first glance, they seemed like twins separated by a few years of refinement. But under the surface, the differences told a deeper story—one about evolution, innovation, and the delicate balance between tradition and modernity.
In 2011, when Porsche unveiled the 991.1, it was immediately clear that this was not just a tweak of the familiar formula. The design was unmistakably 911, but there was a newfound sense of proportion. The wheelbase had grown longer, the track was wider, and yet the car was lighter than the outgoing 997. Porsche's use of aluminum-intensive construction had worked magic.
The headlights retained the classic round shape, a reassuring nod to tradition, while the bodywork flowed with a modern elegance. The front bumper was clean and understated, and the taillights—thin, horizontal slashes of red—gave the rear an air of refinement.
But the real magic lay beneath the rear engine cover. The 991.1 Carrera models were the last bastion of naturally aspirated flat-six engines in the 911’s core lineup. The base Carrera featured a 3.4-liter flat-six, a rev-happy marvel that produced 350 horsepower. For those seeking more, the Carrera S came with a 3.8-liter flat-six, delivering 400 horsepower. These engines sang a mechanical symphony, their power building to a crescendo that peaked near 7,400 RPM. It was the kind of driving experience that connected you to the road, to the car, and to decades of Porsche history.
Paired with these engines was either a 7-speed manual transmission—a nod to the purists—or the 7-speed PDK (Porsche Doppelkupplung), a dual-clutch gearbox that shifted faster than thought. The 991.1 was a car that rewarded skill, patience, and a love for high-revving thrills.
By 2016, Porsche was ready to unveil the 991.2. At first glance, it looked familiar—an evolution, not a revolution. But this was a car that bore the weight of a major transformation. The exterior refinements were subtle but purposeful: full-LED headlights glared with a sharper intensity, and the front bumper’s air intakes were larger, more aggressive, hinting at greater power and efficiency. At the rear, 3D-effect LED taillights lent a modern, sculpted look, and the engine cover now bore sleek vertical slats, a clue to the changes within.
And what changes they were.
Beneath the skin, the heart of the 911 had evolved. The once high-revving, naturally aspirated engines of the Carrera lineup had given way to turbocharging. This was no longer the realm of just the Turbo models—the Carrera and Carrera S now featured 3.0-liter twin-turbocharged flat-six engines. The base Carrera produced 370 horsepower, while the Carrera S delivered 420 horsepower.
This shift to turbocharging was monumental. Where the 991.1 had built its power with a gradual, linear climb, the 991.2 offered instant torque. Power surged from as low as 1,700 RPM, making acceleration effortless and immediate. The sound had changed, too—a deeper growl, punctuated by the faint whistle of the turbos. Some purists mourned the loss of the old high-revving wail, but there was no denying the 991.2 was faster, more efficient, and more versatile.
The 7-speed PDK gearbox in the 991.2 had been refined to match this new character. Shifts were now even quicker, smoother, and almost telepathic in their precision. For those who still craved the tactile joy of a manual, the 7-speed stick shift remained, offering that mechanical connection Porsche had long been known for.
Driving the 991.1 was an exercise in precision and passion. You pushed the engine to the redline, feeling the power swell as the flat-six screamed its mechanical song. The handling was crisp, the steering direct, and every gear change—whether manual or PDK—felt like an extension of your will. This was a car that rewarded effort, that demanded you engage with it fully.
The 991.2, in contrast, felt like a refined athlete. The turbocharged engines delivered power effortlessly, making the car feel quicker in every scenario. The torque was always there, ready to launch you forward with a surge that pinned you to your seat. The handling was still sharp, the steering precise, but there was a sense that the car had matured. It was more capable, more composed, and somehow more forgiving.
Yet despite these changes, the soul of the 911 remained intact. Whether naturally aspirated or turbocharged, manual or PDK, both versions of the 991 offered a driving experience that was unmistakably Porsche.
The story of the 991.1 and 991.2 is one of tradition meeting transformation. The 991.1 was the last hurrah for naturally aspirated Carreras, a car that celebrated the raw, unfiltered joy of high-revving engines. The 991.2 embraced the future, adopting turbocharging to enhance performance, efficiency, and everyday usability.
Choosing between them isn’t just about picking a car—it’s about choosing an experience. Do you crave the raw, mechanical connection of the 991.1, or do you appreciate the modern speed and effortless power of the 991.2? Whichever path you choose, both are milestones in the Porsche 911’s journey—testaments to a legacy that balances evolution with tradition, and innovation with soul.

The cylinder number and position (six, horizontal) remained the same as before, but the displacement has been reduced to 3.0 liters (from 3.4 liters) and a pair of turbos were added. Power in the Carrera 2 Cabriolet gained 20 hp and some 40 lb-ft of torque vs the prior generation. More importantly, the torque available way quicker, from just 1,700 rpm.

Porsche purists might moan that the flat-six engine in the rear is no longer naturally aspirated, but with more power and torque, improved efficiency and some advanced interior tech giving this 911 an even bigger breadth of ability than before, this facelifted 991-generation model carries on where the old car left off. It lost a touch of that high rev zing from the old car.

The switch to turbocharging delivers predictably faster acceleration, with 0 - 60 mph taking just 3.9 seconds with the PDK transmission and Sport Chrono optioned. The quarter mile is dispatched in 12.2 seconds and the top speed for the open top Carrera S is 190 mph. These numbers are pretty impressive for an open top 911 that is just as comfortable driving around town as it is on back roads on spirited runs.

The new downsized flat-six gets forced induction, more power and greater efficiency, just like in the basic refreshed 911 Carrera, this time mated to a four-wheel-drive system nicked wholesale from the Turbo. Apparently one in three 911 buyers opt for a four-wheel-drive variant, so this is an important car to get right. The 3.0-liter twin-turbo flat-six in the 911 Carrera 4S is good for 414hp and 368 ft lbs of torque.

A new turbo flat-six engine is the headline news. Still super fast and surefooted all year round. The revised four-wheel-drive 911 makes the car's appeal on year-round, any-occasion usability even stronger. The 911 Carrera 4S receives a series of subtle styling updates as part of a reasonably comprehensive mid-life facelift.

The 991.2 Targa did get some mild design changes, but they are all inline with the rest of the 991.2 changes. Despite the mild styling revisions, it’s a dramatically different car in terms of its engine. The iconic and highly regarded naturally aspirated 3.4-litre flat-six engine has been ousted for a twin-turbocharged 3.0-litre.

Porsche really has hit its brief with the turbocharged Carrera GTS Cabriolet. It is hugely capable on the road, easy to live with on a daily basis, and come the weekend, it’s massively fast on track. For the money, and for drivers who really want just a little more 911, but without the mind-bending speed of a Turbo or uncompromising nature of a GT3, then this is the car for you.

Ultimately, the Carrera 4 GTS is the ideal all-round 911. Its bag of tricks gives you accessible, astonishing performance on the right road – but its price tag and comfort levels make it a little more acceptable for everyday use than a GT2 or GT3. The GTS scores particularly well on the practicality to performance ratio. Rear seats plus and AWD works for those cold winters and families.

The GTS 4 Cabriolet reminds us how awesome Porsche cars are. This is a 911 that can be used as a regular car, an all weather convertible 911 that does everything really well. And when you want to push hard, the car transforms into a true sports car, a car that no enthusiast will ever complain about. In GTS specification the Cabriolet is now better than ever.

The 911 Targa 4 GTS isn't the fastest or top performing 911. It is heavier, softer and not as fast as every other GTS model. But we still love it. The Targa 4 GTS has amazing performance coupled with the sexiest body in the business. In GTS trim the body looks even better. The car you get when you can only get one and need it for fun weekends, daily driving and fancy dinners.

Top Speed: 198 mph
At the heart of the 991.2 911 Turbo is a twin-turbocharged flat-six with 540 horsepower and 523 pound-feet of torque. That’s a meaningful 20 more horses than the 991.1 Turbo. Improvements that come from increases in boost and fuel-injection pressures. Rounding the skidpad, the Turbo posts 1.02 g’s relatively easily. The standard four-wheel steering conspire to hide the fact that 62 percent of the Turbo’s 3656 lbs sits over rear wheels.

The Cabriolet version of the 991.2 Turbo got the same updates as its coupe sibling. The engine in the 991.2 911 Turbo Cabriolet is a twin-turbocharged flat-six with 540 horsepower and 523 pound-feet of torque, up a decent 20 more horses versus the 991.1 Turbo Cab. Improvements that come from increases in boost and fuel-injection pressures. Rounding the skidpad, the Turbo posts 1.02 g’s relatively easily. This is open-top fun.

The purpose of the T is to create a driver-focused 911. It has twin-turbo 3.0L flat-six with 370 horsepower and 331 lb-ft of torque. A 7-speed manual transmission comes standard along with a shorter final-drive ratio and the limited-slip differential. Porsche Sport Exhaust (PSE) is also standard. PASM sport suspension comes standard in the T, which lowers the chassis by 0.4 inches relative to the base Carrera and allows for two modes of dampening.
Porsche 911 (991) Special Editions
Porsche 991 Special Edition & Race Models
The 991 generation truly shines when it comes to its special editions. Take the anniversary edition, a visual masterpiece with a potent 430 hp flat-six, courtesy of a power kit. The 991 GT3 initially sparked controversy due to its lack of a manual option, yet its performance was undeniable, pushing the boundaries of what a sports car could achieve. Meanwhile, the Turbo S models continued to impress with their mind-bending speed and grand touring comfort, while the track-focused GT3 RS remained the weapon of choice for serious drivers. But for many, the pinnacle of the 991.1 generation was the 911 R, a purist's dream with its 4-liter naturally aspirated flat-six and six-speed manual gearbox – arguably one of the greatest modern 911s.
Porsche clearly listened to its customers for the 991.2 special editions. The GT3 returned with a manual gearbox option, and they introduced the GT3 Touring: a more understated version with no rear wing and a manual-only configuration. Then there was the new Speedster, a thrilling reminder of the joys of a manual transmission. However, the undisputed king of the 991.2 generation was the GT2 RS. This beast claimed the title of the fastest and most powerful 911 ever, even setting a blistering lap record at the Nürburgring Nordschleife.

Uses the wider body from a Carrera 4S (but remains only RWD) and is lower than a standard Carrera by 10mm. The 20 inch-alloys are a modern take on the original Fuchs wheels, and the seats are finished in “Pepita” cloth. Includes PASM, sports exhaust and powerkit flat six.

Top Speed: 197 mph
Car and Driver nailed this car when they said..."Launch control puts the computer in charge and sends the 3741-pound Turbo S Cab to the far side of 60 mph in just 2.8 seconds. A quarter-mile that nearly breaks into the 10s—11.1 seconds at 124 mph—attests to how serious this car gets when provoked. We saw 1.0 g on the skidpad and a stopping distance of 151 feet, both strong numbers abetted by the hilariously staggered Pirelli P Zeros".
Porsche 911 GT3 RS (991)
Years: 2015-2016

Torque: 339 ft lbs @ 6250 rpm
0-60 mph: 3.1 seconds
Top Speed: 193 mph
For those who want more extreme performance, handling and track-day bragging rights, the RS is it. Too extreme for some, especially on the street, but on track it is exceptional. Only marginally quicker than the 991 GT3 that it is based on, but it delivers that performance with a different character. Massive grip, massive downforce and more extreme than the GT3. It delivers 80 per cent of the downforce of the full-on GT3 R race car.

Sticking to their strengths, Porsche has created the most sought after car in its line-up, the 2017 Porsche 911 R. We have seen numerous rumors about this car for a couple of months now and this time we finally get to see it. The new Porsche 911 R with 4-litre naturally aspirated flat-six engine with a six-speed manual gearbox is coming to us for sure. It's lighter and faster with its engines pumping out 493 bhp at 8,250 rpm and 333 lb-ft at 6,250 rpm.

The 2016 Carrera and Boxster Black Editions add some extra niceties for a value-adjusted price.

Available in coupe and convertible forms, with rear- or all-wheel drive, each powered by the base 350-hp 3.4-liter flat-6 engine, and adds other design treats too.

The GT2 RS's reputation as the most powerful street-legal car is as monstrous as this comprehensive guide. Suffice to say, this supercar has been built with the best Porsche has to offer. It's not bragging, it's just facts. There is no doubt that the new GT2 RS is the pinnacle of the 911 in terms of performance. It is simply the fastest 911 in history, and that’s a fact. It is the quickest production car to lap the Nürburgring.

Top Speed: 193 mph
Matt Prior from Autocar nails the 991.2 GT3 RS: “While I don’t think the 3 communicates any better than a 2, the messages it does transmit are superior: you can feel that it’s lighter, more willing to turn, easier and more satisfying to ease onto the throttle and keep it pinned". It’s why this car is only a few seconds slower than a 2RS around the Nürburgring despite being almost 200bhp down. The best driver’s car around.
Porsche 911 Speedster (991)

Make no mistake that the Speedster is an absolutely fitting conclusion to the 991-generation. The Porsche 911 Speedster is an ingenious amalgamation of the latest technologies on offer. A 502-horsepower engine, without turbochargers. A modern transmission, with just one clutch. A state-of-the-art suspension and chassis, with an unsullied purity. The list goes on. The only drawback is that rarity and price.

As the rules do not permit higher output engines, the engine for the 991 RSR was taken from the 997 GT3 RSR 4.0 and the development work focused on the chassis, body, aerodynamics and the gearbox. A wishbone front suspension replaced the McPherson struts used in 997. A new development was the lightweight gearbox.

Two decades after the different 911 GT1 cars the mid-engined 911 is back! In order to install a proper diffuser under the rear end of the 991, the engine had to make room for it and the engine/transmission unit was rotated 180 degrees. The extended rear diffuser, a top-suspended rear wing and the new side mirrors help to increase downforce with reduced drag.

This car was officially called as the 911 GT2 RS Clubsport, but the name is rather misleading. The car was not built for the GT2 racing class which is long extinct and club sport has stood for Porsche club track days while this non-streel-legal car is a real racing car. Finally, the car was based on the 991 GT2 RS, which already had the Clubsport version.

This was the fourth version of the 991 RSR - the first two came with the rear engine, then the first mid-engine version was launched (all 4.0-litre) and finally the mid-engined RSR 4.2 with the largest 911 engine ever made. The increase in the engine capacity is a question mark as on production models the capacities are decreased and turbochargers are used.

Porsche 911 (991) Buyer’s Guide (2012 - 2019)
The Porsche 911, a paragon of automotive excellence, has continually evolved to balance tradition with innovation. The 991 generation, produced from 2011 to 2019, exemplifies this harmony, offering a blend of modern technology and classic 911 characteristics. This guide provides prospective buyers with a comprehensive overview of the 991 series, covering its history, model variations, performance attributes, common issues, and essential considerations for ownership.
Model History
Introduced in late 2011, the 991 series marked a significant advancement over its predecessor, the 997. It featured a longer wheelbase, wider front track, and an aluminum-steel composite construction, resulting in improved handling and reduced weight. The initial lineup included the Carrera and Carrera S models, both available in coupe and cabriolet forms. The Carrera housed a 3.4-liter flat-six engine producing 350 horsepower, while the Carrera S boasted a 3.8-liter flat-six with 400 horsepower.
In 2012, Porsche expanded the 991 range with the all-wheel-drive Carrera 4 and 4S, followed by the Targa variants in 2014, which paid homage to the classic Targa design with a modern twist. The pinnacle of naturally aspirated engines in the 991 series was the GT3, introduced in 2013, featuring a 3.8-liter engine delivering 475 horsepower. The 991.1 generation concluded in 2016, making way for the 991.2, which introduced turbocharged engines across the Carrera lineup, enhancing both performance and efficiency.
Performance and Driving Experience
The 991 series is celebrated for its dynamic driving experience, offering a harmonious balance between comfort and performance. The Carrera models provide ample power for spirited driving, with the Carrera S achieving 0-60 mph in approximately 4.1 seconds. The introduction of the seven-speed manual transmission was a notable innovation, providing an extra gear for improved fuel efficiency and a unique driving engagement.
The 991's chassis dynamics benefit from the extended wheelbase and wider track, offering enhanced stability and cornering capabilities. The electromechanical power steering, a first for the 911, provides precise and responsive feedback, though some purists note a slight reduction in tactile sensation compared to hydraulic systems. Optional features such as Porsche Active Suspension Management (PASM) and dynamic engine mounts further refine the driving experience, allowing for adaptability between comfort and sport-oriented settings.
Common Issues and Maintenance
While the 991 series is generally reliable, prospective buyers should be aware of certain issues:
Cooling System: Debris accumulation in the front air intakes can lead to clogged radiators and condensers, potentially causing overheating. Regular inspection and cleaning are recommended to maintain optimal cooling performance.
Engine Components: Faulty crank sensors and coil packs have been reported, leading to engine misfires or stalling. Ensuring these components are in good condition during pre-purchase inspections is crucial.
Suspension Wear: Worn bushes, tired top mounts, and leaking dampers can affect ride quality and handling. Listen for unusual noises during test drives and have the suspension system thoroughly checked.
Porsche Dynamic Engine Mounts (PADM): These mounts can fail over time, impacting ride comfort and handling precision. Regular maintenance and prompt replacement when necessary are advised.
Adhering to Porsche's recommended maintenance schedule is vital. Services are typically due every two years or 20,000 miles, whichever comes first. Utilizing authorized Porsche service centers or reputable specialists ensures that the vehicle receives appropriate care, preserving its performance and value.
Ownership Considerations
The 991 series offers a range of models to suit different preferences, from the base Carrera to the high-performance GT3. When selecting a model, consider the following:
Transmission Choice: The seven-speed manual provides a traditional, engaging driving experience, while the PDK dual-clutch automatic offers quicker shifts and convenience, especially in traffic.
Optional Features: Features such as PASM, Sport Chrono Package, and adaptive sports seats enhance the driving experience but may add to maintenance complexity.
Service History: A comprehensive service history indicates diligent maintenance, which is crucial for long-term reliability. Ensure all services have been performed on schedule and by qualified technicians.
Pre-Purchase Inspection: Engaging a Porsche specialist to conduct a thorough inspection can identify potential issues and provide peace of mind.
Market and Value
As of December 2024, the 991 series holds its value well, reflecting its desirability and performance. Prices vary based on model, mileage, condition, and optional features. Early Carrera models may start around $50,000, while well-maintained Carrera S, Targa, and limited editions like the GT3 command higher prices. The 991.2 models, with their turbocharged engines, generally fetch a premium over the 991.1 variants.
The Porsche 911 (991) series stands as a testament to Porsche's commitment to blending heritage with innovation. Its range of models caters to diverse driving preferences, from daily usability to track-oriented performance. Prospective buyers should conduct diligent research, prioritize vehicles with comprehensive service histories, and consider professional inspections to ensure a rewarding ownership experience. With proper care, a 991 can provide years of exhilarating driving and uphold the esteemed Porsche legacy.
