Porsche 991: The seventh generation of the 911

With the Porsche 991, the sports car manufacturer presents the seventh generation of the legendary 911 in 2011. The first version, the 991.1, is considered by many Porsche enthusiasts to be (once again) the last "real" 911, as it is the last model to come with a naturally aspirated engine. More well-trained and more powerful - these are Porsche's hallmarks for the 991. For the sports car manufacturer, the vehicle is a bestseller. From 2011 to 31 October 2018, 217,930 examples of the Porsche 991 were built. What makes the successor to the Porsche 997 different? Externally, the vehicle differs only slightly from its predecessor model, the Porsche 911. The wheelbase has been increased by ten centimetres. increased by ten centimetres. In addition, the Porsche 991 is 5.6 centimetres longer. The LED tail lights are narrower than on the 997. The front apron has larger air intakes. air intakes. As on the Porsche 993, the exterior mirrors are again attached to the doors and no longer to the window triangle. The six-cylinder boxer engine of the 991 has a displacement of between 3.4 and 3.8 litres with direct petrol injection. Porsche achieves an improvement fuel consumption: thanks to the start-stop technology in combination with other changes, fuel consumption can be reduced by twelve percent. by twelve per cent. Starting with the facelift under the internal designation 991.2, Porsche also uses a turbocharged engine in the basic model. The second generation of the 991 thus ushers in a new era. Compared to its predecessor, the 997, the 991 is flatter, has a longer wheelbase and a wider track. This again improves the driving dynamics of the seventh 911 generation. Furthermore, Porsche places even more emphasis on comfort compared to the predecessor, including the PDK (Porsche double clutch transmission) and a retractable hardtop in the convertible. The power spectrum of this 911 generation ranges from 350 hp (257 kW) in the first 991.1 Carrera to 700 hp (515 kW) in the racing and sports model 911 GT2 RS. As is typical for Porsche, numerous other model variants and engine versions appear in the years following the initial launch. The production period covers the years 2011 to 2019, before the 991 finds its successor in the current 992. The outstanding models of the 991 series include:

991 GTS
991 R
991 Jubi / „50 Years of 911“
991 Targa
991 Turbo
991 GT3 / GT3 RS incl. „Weissach Edition“

Porsche 991.1 Carrera PreFacelift

Porsche presents the first model generation of the 991 at the 2011 International Motor Show (IAA). At that time, Porsche initially presents only the 911 Carrera and the Carrera S, both models in the coupé version. Compared to the predecessor, the displacement of the basic model is reduced from the former 3.6 litres to 3.4 litres. Due to the higher revving power of the engine, the engine nevertheless produces 5 hp more than the predecessor (with the same torque of 390 Newton metres) and now offers 350 hp (257 kW). In the Carrera S, Porsche continues to rely on 3.8 litres of displacement, while the engine is additionally more rev-happy. At up to 8,000 revs, the 991.1 Carrera S produces 400 hp (294 kW). It offers a maximum torque of 440 newton metres.

A further innovation compared to its predecessor was developed by Porsche in the area of power transmission: the 991 was the first series-produced vehicle ever to be delivered from the factory with a seven-speed manual gearbox. As an overdrive, the seventh gear contributes to reducing fuel consumption and thus helps to meet and achieve CO2 emission targets. On the body side, the 991 also features an innovation: it is the first Porsche model to be manufactured in a mixed construction of aluminium and steel. The development goal was a lighter model compared to its predecessor. The previous 911 generations were always heavier. This is related to the growing demands of customers for comfort and safety. A bodyshell of a 993 (1993), for example, weighed only 215 kilograms, while the 997 (2003) already weighed 280 kilograms. Despite a larger wheelbase, a weight reduction is possible in the 991 compared to the older models. The direct predecessor weighed 1490 kilograms as a 911 Carrera, while the 991 only weighs 1455 kilograms. As a typical 911, the 991 is designed to combine sporty performance with a high level of comfort and suitability for everyday use. Even a regular 991 Carrera S offers similar performance on the Nordschleife as the GT3 version of its predecessor, the 997 (7:40 minutes).

Porsche 991.2: Facelift from 2015

The 991.2 facelift of 2015 marks the end of a roughly 50-year era in several respects. For the first time, naturally aspirated engines in the 911 were completely replaced by turbo engines. Likewise, in the course of downsizing, the displacement dropped from the already downsized 3.4 litres to just 3 litres. Equipped with two turbochargers, the 991.2 nevertheless has more power than the 991.1 and now offers 370 hp (272 kW). In the Carrera S version, the output even increases to 420 hp (309 kW). This significant increase in power is due on the one hand to the exhaust gas turbochargers with their modified compressors. Furthermore, a special exhaust system as well as an engine control system characterised by special tuning contribute to the increase in power.

In addition to the biturbo equipment, the basic engine in the 991.2 has also been modified. The innovations include adjustable exhaust camshafts. Furthermore, the injection nozzles are now centrally located in the combustion chamber. This should contribute to lower fuel consumption and higher exhaust gas quality. As with its predecessor, Porsche relies on the VarioCam Plus system. This proven system ensures variable adjustment of the stroke and the opening times of the valves on the intake side. Porsche also relies on a new type of plasma coating for the cylinder liners. Various weight savings are also possible in the engine area. Thus, the plastic oil pan weighs 2 kilograms less and the aluminium crankcase saves 1.5 kilograms in weight. The new biturbo power unit also requires a new type of air routing system in the rear of the 991.2. This applies equally to the charge air cooling as well as the combustion air. The combustion air is drawn in centrally by the engine in front of the rear spoiler. The air reaches the turbochargers via two connections on the side of the air filter box through two intake ducts. The air compressed by the turbochargers then flows through two intercoolers. These are located to the side behind the wheel arches. Via the throttle valve, the air heated by compression reaches the intake manifold of the turbo engine. To cool the combustion air, two additional ducts return the air to the intercoolers via the air grille. In addition to the comprehensive modifications to the drive, Porsche only relies on minor exterior changes in the 991.2 facelift. These include wider rear wheels as standard. Furthermore, from this model update onwards, PASM, which was formerly an extra charge, is standard equipment. This is an in-house active suspension system that goes by the name of Porsche Active Suspension Management.

Porsche 991 Turbo

The standard top models, the 911 Turbo and 911 Turbo S, also come with a number of new features and innovations in the 991. These include rear-axle steering. This ensures greater agility when cornering and also a higher degree of stability when the 911 Turbo is running straight. The rear wheels of the Turbo can be counter-steered or co-steered by up to 2.8 degrees. The extent of the counter-steering or steering depends on the respective driving speed, the steering angle and the driving situation, among other things. This functionality virtually changes the wheelbase by minus 250 to plus 500 millimetres. Compared to its predecessor, the 997 Turbo, the 991 Turbo still features more precisely adjustable front and rear spoilers. The 911 Turbo extends these in three stages in each case.

The 991 Turbo has a 3.8-litre six-cylinder engine with biturbo charging. In the 991.1 version, the regular Turbo produces 521 hp (383 kW), while the Turbo-S model comes with 560 hp (412 kW). Since the facelift of 2016, the engine of the Turbo S offers 580 hp (427 kW). Furthermore, the Turbo models are equipped with the PASM system as well as the special roll stabilisation PDCC (Porsche Dynamic Chassis Control PDCC). The equipment of the 991 Turbo models is rounded off by the standard Sound Symposer. This transmits the intake noises of the turbo engine into the interior of the 911 via a diaphragm.

Agiler in bends and more stable when driving straight ahead thanks to the rear-axle steering - this characterises the 911 Turbo. The rear wheels steer in up to 2.8 degrees depending on the speed, the steering angle and the driving situation. The vehicle has a front and a rear and a rear spoiler that can be extended in three stages. The Turbo produces 520 hp, the Turbo S 580 hp. As standard, the Turbo is equipped with a sound symposer as standard, which transmits the intake noises of the turbo engine via a membrane into the interior. With the model introduced variable damping (Porsche Active Suspension Management) and roll stabilisation (PDCC).

Porsche 991 Turbo S Exclusive

Porsche is presenting a particularly powerful and rare model variant of the Turbo S in 2017. Under the designation Turbo S Exclusive, Porsche is offering a special model limited to just 500 units. Its biturbo-charged six-cylinder features a special power kit. It now produces a whopping 607 hp (446 kW) and offers a maximum torque of 750 Newton metres. This power unit accelerates the exclusive Turbo from 0 to 100 kilometres per hour in under 3 seconds, while the 200 mark is cracked after just 9.6 seconds. In terms of fuel consumption, the Turbo S Exclusive is no better than the standard model, requiring 9.1 litres of Super Plus (98 octane) combined per 100 kilometres.

Porsche 991 Targa

Targa models have a long tradition at Porsche and the special roof design has been available for the 991 since 2014. This Targa generation was presented at the Detroit Motor Show. In keeping with the tradition of older Targa models, the 991 also has a one-piece rear window and a soft top with a fixed roll bar. The characteristic Targa bar including the corresponding lettering is particularly striking. The roof section is located between the windscreen (A-pillar) and the Targa bar (which corresponds to a B-pillar). Similar to regular convertibles with folding roofs from other manufacturers, the roof section can be extended automatically. Here, the complete rear window module is first extended to the rear. Parts of the Targa bar are swung out to the left and right for this purpose. The Targa roof can be stored behind the emergency seats. Finally, the rear window module returns to its original position. Similar to the original Targa models, which can be traced back to the 964 model, the doors are frameless. The area between the A-pillar and the B-pillar is thus completely open. The 991 Targa is available in Targa 4, 911 Targa 4 S and 911 Targa 4 GTS versions. The engine versions correspond to the Coupé variants of the corresponding version.

The 991 GTS improves driving dynamics

In 2014, Porsche introduced the 991 GTS, a kind of intermediate model, as the Carrera GTS, Carrera 4 GTS, Carrera GTS Cabriolet, Carrera 4 GTS Cabriolet and Targa 4 GTS, forming an intermediate model between the Carrera S and GT3. In the first model generation 991.1, Porsche equips the 911 GTS with a 430 hp (316 kW) engine that offers a maximum torque of 440 Newton metres. In the 911.2 model generation, Porsche raises the output of the GTS to 450 hp (331 kW). Furthermore, it has improved technical equipment compared to the Carrera and the Carrera S. These include larger brake discs, which measure 350 millimetres at the front and 330 millimetres at the rear in this model. But in the 911.2 model generation, the GTS has a sports exhaust system placed in the middle. Porsche offers the GTS variant in the Carrera GTS, Carrera 4 GTS (with all-wheel drive), Carrera GTS Cabriolet, Carrera 4 GTS Cabrio and Targa 4 GTS versions.

It features upscale equipment and more driving dynamics: The brake letters are larger, the sports exhaust system is centrally located on the 991.2 model. Its multimedia package is expanded. With the Sport Chrono Package, the driving modes Normal, Sport, Sport Plus and Individual can be selected on the GT sports steering wheel. The Porsche dual-clutch transmission can be ordered as an option. Porsche Stability Management has also been expanded in the GTS to include a Sport mode. A lift system has been added to the front axle, with which the front of the 991.2 can be raised by around 40 millimetres up to a speed of 35 kilometres per hour.Additional equipment features include improved multimedia functionality and a Sport Chrono Package. From the 991.2 generation onwards, this features mode switches derived from the 918 Spyder, which have four driving modes. In addition to "Normal" and "Sport", the modes also include "Sport Plus" and "Invididual". The optionally available PDK offers further functions, including Launch Control (traction control) and a special function called Sport Response. This ensures a particularly fast response for a period of 20 seconds. Furthermore, the PSM system (Porsche Stability Management) on the 991 GTS has a sport mode. The front axle of the car can be optionally equipped with a lift system that can raise the front of the vehicle by about 40 millimetres (up to a speed of 35 kilometres per hour). The 4x2 version of the Porsche 991 GTS also comes with the wider rear.

Porsche 991 Speedster

The strictly limited 991 Speedster marks the end of the 991 model series, which will be discontinued in 2019. Porsche only produces 1948 examples of this model. The number of units corresponds to the year in which the forefather of all Porsche sports cars was presented, the first 356 Roadster. The main special feature is the drive, which is based on a naturally aspirated engine with a whopping 510 hp (375 kW). It will appear in 2019 as the last model of the 991 generation. For the time being, Porsche will only sell the car on the US market. The 991 Speedster is a roadster that, unlike the convertible, has no classic soft top. Only a tarpaulin protects against the weather. A striking design feature are the Speedster-typical humps that rise up behind the passengers. A double exhaust system adorns the rear. Furthermore, the Speedster differs from the regular convertible by the shortened front and side windows.

The Speedster takes over the rims from the 991 GT3. It still has carbon kermic brakes (PCCB) as standard. In terms of its sportiness, the Speedster stands out by dispensing with heavy additional equipment. For example, it does not have air conditioning ex works. In the interior, carbon dominates in the sense of weight reduction. Instead of storage compartments, the Speedster has nets. Door handles are replaced by loops. The Speedster continues to rely on the lightweight manual six-speed gearbox familiar from the 911 R. This is different from the regular seven-speed. This is four kilograms lighter than the regular seven-speed manual. Compared to the Porsche double-clutch transmission from the normal 991 Carrera, 18 kilograms are saved.

Loud and limited: The 991 R special edition

Under the additional designation R, Porsche is presenting a special model in 2016 that is limited to 991 units. The number of units corresponds to the designation of the model line. The 991 R features a lightweight construction and spartan equipment. Even with the Pepita-style seat covers, the limited edition car is supposed to be reminiscent of older models in the 911 series. It is powered by an engine based on that of the 911 GT3 RS. The vehicle uses a manual gearbox exclusively and its equipment is deliberately intended to follow the predecessor models. The 500 hp (368 kW) engine transmits its power exclusively via a manual gearbox. It accelerates the car from 0 to 100 kilometres per hour in 3.8 seconds. The sports model reaches a top speed of 323 kilometres per hour. Furthermore, the limited special model has a retractable rear wing. This means it also has a wider rear than the 911 Carrera, whose rear width it exceeds by around 44 millimetres. The aim of this design is to achieve even better road holding. A striking visual design feature are the stripes that run the entire length of the car. They are in the colours red or green. Other special features distinguish the 991 R:

Seats in Pepita fabric,
A restrained interior,
lightweight construction.

Since the R is designed in particular for sportiness and less for comfort, it is also a louder car compared to the series versions. Porsche had already sold all 991 examples of the 991 R before construction began. Its new price was around 190,000 euros. Even today, the used car model fetches prices of between 300,000 and 500,000 euros.

Special edtion: Porsche Targa 4 GTS "Exclusive Manufaktur Edition"

Porsche is introducing a special limited edition Targa model in November 2018 called the Targa 4 GTS Exclusive Manufaktur Edition. Porsche is offering only 250 examples of the special model on the German market. The presentation of the exclusive model took place in a Porsche showroom on the island of Sylt. It features the three-litre boxer engine with biturbo and 450 hp (331 kW) that also powers the regular Carrera GTS. A special feature is found in the paintwork. This is in agate grey metallic and also has trim elements in the colours brilliant silver and white gold metallic. These replace the black components otherwise used on the GTS models. The Targa 4 GTS Exclusive Manufaktur Edition also has an exclusive colour design in the interior, in which brown tones dominate.

The 991 Jubi: "50 Years of the 911

The Porsche 911 celebrates its 50th anniversary in 2013. For the sports car manufacturer, this is a welcome occasion for a new special model in 2013, which will be launched under the name "50 Years 911". The chassis is based on the 991 Carrera S. On request, Porsche will equip the anniversary model with a factory performance upgrade. In addition, the anniversary car has the wider rear from the Carrera GTS model variant. The models with all-wheel drive also have this wider rear. Another special feature is the paintwork and the interior design. The interior is dominated by a vintage style in the colours Agate Grey Geyser Grey and Black Dark Silver. The two-tone fabric of the seat covers follows a Pepita style. The style is reminiscent of the original 1963 model. Exterior paint finishes available on the special model include Geyser Grey Metallic, Graphite Grey and Black. Optical stylistic adaptations can still be found in the ventilation grilles of the bonnet. The wheels of the special model are also adapted to the Fuchs rims typical of the early 911s. The anniversary Porsche is adorned at the rear with a nameplate reminiscent of the early phase. A nameplate in the design of the first Porsche generation and the red number 50 can be found at the rear. Like the GTS, the 4x2 model has a wide rear.

For an additional charge, Porsche offers an option package for the anniversary model. This is based on the components Porsche Communication Management (PCM), the Sport Chrono Package (which offers, among other things, stopwatches, dynamic engine mounts and launch control for starting off), a parking assistant, heated seats and telephone module.

For an extra charge, Porsche offers an option package for the anniversary model.

Porsche 991 GT3

In the tradition of the previous GT3 models (996 and 997), the 991 GT3 also has the characteristic large and fixed rear wing. The front and rear aprons are specially made for the model. Just like the 997 GT3, the 991 also has the centrally positioned double-pipe exhaust system under the licence plate holder. For the first time, the 991 GT3 uses an engine that differs from the Mezger design. The 3.8-litre unit with direct injection produces 475 hp (350 kW). The particularly rev-happy engine reaches up to 9,000 revolutions per minute. A special feature compared to its predecessor was that from the 991.1 generation onwards, the 911 GT3 was only available with a 7-speed PDK. Nevertheless, a weight reduction is possible with the 991 compared to its predecessor. At 1,350 kilograms, it is comparably light as the 996 GT3.

The GT3 RS, built from 2015, is even more powerful. Similar to the 997 GT3 RS 4.0, it produces 500 hp (368 kW). From the facelift of the GT3 in 2017, this was also equipped with the engine of the GT3 RS. This model also has a regular manual gearbox again, at the request of many Porsche fans.

991 GT3 / GT3 RS incl. „Weissach Edition“

The GT3 models of the Porsche 991 have a fixed rear wing on the engine cover. The front and rear aprons were manufactured especially for this model. The centrally positioned exhaust pipes of the models in the years 2006 to 2011 were retained. More power and less NEDC consumption characterise the GT3. Lightweight materials and reduced equipment reduce the kerb weight by around 40 kilograms compared to its predecessors. by around 40 kilograms to 1350 kilograms compared to its predecessors. This makes the 991 GT3 the lightest GT3 since its presentation in 1999. Rear-axle steering and dual-clutch transmission are standard in the GT3. Only the facelifted 991.2 GT3 could be ordered with a manual gearbox. could be ordered.

Light, lighter, Weissach package: In May 2015, the Porsche 991 GT3 RS was added. The boxer engine with 4 litres and six cylinders produces 500 hp, and after the model update in 2018, even 520 hp. even 520 hp. It uses a seven-speed dual-clutch transmission. With the optional Weissach Package, the engineers succeeded in increasing the power and further reduce the weight. The Weissach package was offered in a similar form on the Porsche 918 Sypder. The focus is particularly on weight reduction, which creates maximum proximity to racing. Compared to the 911 GT3 RS, it is another 18 kilograms less. The Weissach package could optionally be supplemented with magnesium lubrication wheels painted in Platinum. The vehicle is 11.5 kilograms lighter.

Porsche 991 GT3 R

With the 991 GT3 R, Porsche is presenting another performance-enhanced version of the GT3, which will be in use from 2019. The presentation took place before the 24-hour race at the Nürburgring. The GT3 R is based on the standard RS. However, the boxer engine of the GT3 R produces 550 hp (404 kW) and thus 50 hp more than the RS. The power unit is also designed to develop power more evenly over a wider rev range. Porsche has also optimised the aerodynamics of the GT3 R. The newer racing GT3 R also has a new engine. The newer racing GT3 also has wider wings, which help the GT3 R to achieve improved downforce. In addition, the GT3 R has wider tyres and new wishbones. A striking design feature is the modified rear apron. This exposes the view of the nested diffuser.

Porsche 991 GT3 Touring: modifizierter GT3 mit Touring Paket

The so-called Touring Package makes the GT3, which is designed for racing, a more elegant vehicle. The most striking difference to the regular GT3 is the absence of the protruding rear wing. The Touring also has a rear spoiler. However, like the classic 991 Carrera, it extends automatically at a certain speed. As a small special feature, the Touring package has a tear-off edge in the body colour on the spoiler. Porsche also makes its somewhat more comfortable claim clear by the fact that the minimalist Clubsport package is not available for the Touring. The GT3 Touring is also not equipped with the Porsche dual-clutch transmission. Instead, the Touring has a regular six-speed manual gearbox. The Touring is offered exclusively with a manual transmission.

The Touring is in the tradition of the similarly designated 2.7 RS Touring from 1973. Due to the lack of a rear wing, the GT3 Touring is visually more reminiscent of a 991 R. However, it retains the typical GT3 design. However, it retains the typical GT3 features such as wide wheel arches, centrally positioned tailpipes and the angular front apron with its large air intakes. The Touring also retains the headlights and rear lights that were modernised as part of the second 991 model generation and can be found on the GT3 Touring. Furthermore, a discreet emblem at the rear of the GT3 Touring indicates the Touring version. In contrast to many special models of the 991, the Touring does not have a limited number of units. In the Touring's interior, Porsche uses leather instead of Alcantara.

Porsche 991 GT3 RS

Porsche presented the 991 GT3 RS model variant for the first time in 2015. In the 991.1 model generation, the GT3 RS produces 500 hp (368 kW), which is available from the high-revving naturally aspirated engine at 8,250 revs. It offers 460 Newton metres of torque at 6,250 revolutions per minute. From the 2018 model year, the 991.2 GT3 RS version is equipped with a performance-enhanced engine with 520 hp (383 kW), which has a torque of 470 Newton metres. In tune with the powerful power unit, the GT3 RS receives optimised chassis tuning. The freshly calibrated rear axle steering is especially designed for precision and dynamics. As a road-going race car, the fastest GT3 RS accelerates from 0 to 100 kilometres per hour in 3.2 seconds and achieves a top speed of 312 kilometres per hour.

The GT3 RS is available with several packages on request. At no extra charge, Porsche offers the racing car with a Clubsport package. This includes racing elements such as a roll cage, hand fire extinguisher and six-point seat belts. A special equipment variant of the 991 GT3 RS is the Weissach package. This is named after the location of the Porsche development centre in Weissach. The package primarily serves to save weight. The Weissach package is essentially based on carbon components. These characterise the chassis in particular, but also parts of the interior and exterior. Another component of the Weissach package are optionally available magnesium wheels. Thanks to these weight savings, the lightest version of the 001 GT3 RS weighs only 1,430 kilograms.

Porsche 991 GT3 Cup

The 911 GT3 Cup of the 991 model generation is presented for the first time in December 2012 at the Development Centre in Weissach. It is the version of the then still future 991 GT3 developed for racing and motorsport. In 2013, it is used for the first time in the exclusive Porsche Mobil 1 Supercup. From a 3.8-litre boxer engine with six cylinders, the GT3 Cup produces 460 hp (338 kW) at a speed of 7,500 revs. This makes it 10 hp more powerful than its predecessor. Power is transmitted to the rear axle via a six-speed claw gearbox specially designed by the Porsche Motorsport team. For the first time in a one-make cup car, the gearbox is operated via shift paddles on the car's steering wheel. Also newly designed are the GT3 Cup's one-piece racing wheels equipped with central locking, which have a diameter of 18 inches. Likewise, this Cup racing car has wider racing tyres on the front and rear axles. At the front, the tyres grew by two centimetres to now 27 centimetres. At the rear axle, they now measure 31 centimetres with one centimetre more. The Cup also has a specially redesigned brake system. These are internally ventilated disc brakes measuring 38 centimetres. Six-piston monobloc brake callipers made of aluminium are used on the front axle. The rear axle is decelerated by four-piston brake callipers.

During development, special focus was placed on the safety of the racers. The newly developed roll cage protects pilots in rollovers and collisions. With special padding, the bucket seat, which is strongly shaped in the shoulder and head area, can be perfectly adapted to the pilots' body shape. There is a rescue hatch in the roof. This makes it easier to rescue pilots who have had accidents and to secure the track. According to the works drivers, the 991 GT3 Cup is much easier to drive than its predecessors, especially at the limits. Among other things, a new axle geometry contributes to the best possible balance of the car. Porsche will present the improved and performance-enhanced Cup version of the 991 GT3 911 in 2017. This year, the racing car will be used in three Porsche Cups. This version has more displacement and now produces 485 hp (357 kW) from the 4-litre six-cylinder. The extra power is made possible by racing technology and direct petrol injection. Further details contribute to the efficiency and durability of the racing engine in Cup use. This is intended to reduce maintenance costs. For example, Porsche relies on a central oil feed in the GT3 Cup. An internal oil centrifuge ensures optimum oil defoaming within the engine. Furthermore, the power unit has an improved crankshaft with higher rigidity. The bodywork and aerodynamics of the GT3 Cup 991 have also been improved compared to its predecessors. The new front apron, for example, together with the new rear section, contributes to more downforce. This increases grip and performance. From its predecessor, the GT3 Cup directly inherits the wide rear wing, which measures 184 centimetres. Thanks to its weight-saving composite construction of aluminium and steel, the body has a low mass and high rigidity at the same time. Ready for racing, the 991 GT3 Cup weighs 1,200 kilograms.

Porsche 991 GT2 RS

Porsche presents the most powerful version of the 991 model series in 2017 in the form of the GT2 RS. Porsche will unveil the GT2 RS at the Goodwood Festival of Speed in June of that year. The high-performance car features a biturbo-charged 6-cylinder boxer engine that produces 700 hp (515 kW) at 7,000 rpm. The equally enormous torque of 750 Newton metres is available at between 2,500 and 4,500 revolutions per minute. On the body side, lightweight construction dominates the GT2 RS. This includes the use of carbon fibre reinforced plastic in many components. Front and rear lids, rear wings and the wings are made of this material. Another material is polyurethane, which is used to make the front and rear parts. The roof of the racing car is made of magnesium, which as a light metal enables further weight savings. The windscreens of the GT2 RS are also made of a specially weight-reduced lightweight glass. The lightweight construction is rounded off by titanium rear silencers. The powerful drive in combination with the low mass of 1,470 kilograms ensures enormous driving performance. In just 2.8 seconds, the 991 GT2 RS accelerates from 0 to 100 kilometres per hour, while the 200 mark is cracked after just 8.3 seconds.

In September 2017, driver Lars Kern achieved a record time on the Nordschleife. In 6:47.3 minutes, he circled the track in the GT2 RS faster than any previous road-legal sports car. The GT2 RS is complemented by the optionally available Clubsport Package (CS). Porsche is presenting this for the first time at the LA Auto Show in 2018. The Clubsport variant represents the racing version of the GT2 RS. This model is specially manufactured for selected motorsport events and club sport events. Porsche is limiting this car to 200 units.

The Clubsport variant has a further weight reduction as well as numerous equipment features that make it suitable for racing. With a kerb weight of 1,390 kilograms, the Clubsport version is 80 kilograms lighter than the regular variant. On the engine side, there are no changes and the racetrack version also produces 700 hp. Race track features include a roll cage and a single racing bucket seat for the driver secured with six-point harnesses. Furthermore, the Clubsport version features a carbon steering wheel and a colour display (familiar from the 911 GT3 R, model year 2019).

Porsche 991 Carrera T

The Porsche 991 Carrera T, introduced in October 2017, is based on the regular Carrera, but has some special features and equipment characteristics. It is weight-reduced and weighs in at 1,425 kilograms (20 kilograms less than the 991 Carrera). This is achieved by removing the rear seats, using thinner windows at the rear and in the back and by dispensing with insulation material. Unlike the regular Carrera, it is available with a PASM sports suspension including lowering. The 991 Carrera T is also available with a mechanical limited slip differential for the rear axle. For an additional charge, Porsche also offers all-wheel steering for the Carrera T. As standard, power is transmitted via a 7-speed manual gearbox. This has a shorter gear ratio than the regular Carrera. On request, Porsche also offers the PDK dual-clutch transmission for the Carrera T. Depending on the type of gearstick, the Carrera T accelerates from 0 to 100 kilometres per hour in 4.5 seconds (standard gearstick) or 4.2 seconds (PDK).

Porsche 991 as used car

The seventh model generation of the legendary 911 impresses with the familiar virtues of the classic, even during longer use. For all its sportiness, there is a certain degree of suitability for everyday use and comfort. Quality and durability are classic strengths of the 911. During general inspections, the 991's defect rates are very limited. According to the TüV report, the defect rate for axle suspension, shock absorbers, springs and bearings is 0.0 percent. A minor weakness is oil loss, which can occur until the first general inspection. In the convertible versions, some long-term tests criticise creaking soft tops. The ADAC breakdown statistics only focus on battery problems. High workshop costs have to be taken into account. Wear parts such as tyres, clutch and brakes are expensive to replace.
