Drive
The message is clear and unmistakable: force, power and dynamics. With direct fuel injection (DFI) and VarioCam Plus, the uprated 3.8-litre six-cylinder rear engine of the new 911 Carrera GTS models generates 300 kW (408 hp) at 7,300 rpm.

A top speed of 190 mph (306 km/h) is achieved by the rear-wheel models and 188 mph (302 km/h) by the models with all-wheel drive. The Coupé models accelerate from 0 to 62 mph (100 km/h) in 4.6 seconds, the Cabriolet models in 4.8. The optional Porsche Doppelkupplung (PDK) further improves acceleration, reducing these times to 4.4 and 4.6 seconds respectively. The throttle re-sponse is more direct and acceleration is sportier. The engine power is 17 kW (23 hp) higher than that of the 911 Carrera S models. This was made possible by the redesigned intake manifold, the modified cylinder heads and the optimised engine electronics.

911 Carrera GTS models: fuel consumption in l/100 km (mpg) urban 16.8 (16.8) – 15.3 (18.5) · extra urban 8.0 (35.3) – 7.2 (39.2) · combined 11.2 (25.2) – 10.2 (27.7); CO2 emissions 263 – 240 g/km

Efficiency is about getting more from less, and direct fuel injection (DFI) is fitted as standard. With millisecond precision, DFI injects fuel at up to 120 bar directly into the combustion chamber by means of electromagnetically actuated injection valves.

The spray and cone angles have been optimised for torque, power output, fuel consumption and emissions, thus ensuring homogeneous distribution of the air/fuel mixture and, consequently, efficient combustion.

In the direct injection system, the EMS SDI 3.1 engine management system adjusts the injection timing individually for each cylinder and the injection quantity for each cylinder bank. This optimises both the combustion curve and fuel consumption. A hot-film air mass meter takes care of the airflow, so that the combustion chambers contain exactly the right mixture at all times.

Dual injection is implemented at engine speeds of up to 3,200 rpm and triple injection up to 2,500 rpm. The required quantity of fuel is distributed to two or three successive injection processes per cycle.

This strategy achieves faster heating of the catalytic converters after a cold start and produces greater torque in the upper load range.

DFI improves the internal cooling of the combustion chamber by forming the mixture directly in the cylinder. This has made it possible to increase compression (12.5:1), resulting in more engine power and greater efficiency.

Injection is regulated by the electronic engine management system. The exhaust gas cleaning system ensures that emissions remain below the limits of the Euro 5 emission standard, thus helping to protect the environment.

Take a deep breath. The 911 Carrera GTS models are fitted with a variable resonance intake system featuring six switchable, vacuum-controlled valves.

These valves enable the system to switch between power- and torque-optimised geometries for all six air intake tracts to produce higher torque in the mid-rev range. The improved charging of the combustion chamber is made more efficient by a flow-optimised intake duct. The cooling system has been adapted to the increased engine output.

If you want to be heard, it’s better to speak forcefully rather than loudly.

The sports exhaust system follows this principle. Fitted as standard in the 911 Carrera GTS models, it makes the typical Porsche sound more powerful, more resonant, and more sporty.

The sound varies with driving behaviour, ranging from a robust output during normal driving to a distinctly more aggressive tone during performance use. The sports exhaust system is activated using a button on the centre console.

The look, like the acoustics, has a clear accent. The tailpipes are painted black on the outside, and are polished on the inside. They are also nanocoated, which makes them particularly easy to clean.

Accurate and involving: the six-speed manual gearbox is the link to each and every gear. The cable-operated gearshift unit is designed for optimum progression through the gears and the gear lever is insulated from the engine and gearbox. With minimal resistance, the gear lever throw is short and precise, enabling a rapid gearshift action and positive response.

PDK is available as an option for the 911 Carrera GTS models. Gear changes take place in milliseconds, for vastly improved acceleration and lower fuel consumption.

In total, PDK has seven gears at its disposal. Gears 1 to 6 have a sports ratio, with the top speed being reached in 6th gear. The 7th gear has a long ratio and helps to reduce fuel consumption even further. PDK is essentially two half gearboxes in one and thus requires two clutches – designed here as a double wet clutch transmission.

This double clutch provides an alternating, non positive connection between the two half gearboxes and the engine by means of two separate input shafts (input shaft 1 is nested inside the hollowed-out input shaft 2). The flow of power from the engine is only ever transmitted through one half gearbox and one clutch at a time, while the next gear is preselected in the second half-gearbox. During a gear change, therefore, a conventional shift no longer takes place. Instead, one clutch simply opens and the other closes at the same time.

PDK and the manual gearbox deliver power directly to the road. With the optional Sport Chrono Package Plus, you can make it more direct, and sportier. With a rush of adrenaline and euphoria, you are straight into the action.

VarioCam Plus is a variable valve timing system on the inlet side which also features two-stage valve lift. This allows smoother running with comparatively efficient fuel consumption and low emissions – yet with greater power and torque.

This two-in-one engine concept seamlessly adapts in response to driver input. The result is instant acceleration and extremely smooth running.

The timing of each valve is steplessly and electrohydraulically controlled by means of a rotary vane adjuster.

For optimum responsiveness during the warm-up phase, VarioCam Plus will select the higher valve lift setting and retard valve timing. At medium revs and low engine loads, the lower valve lift setting is selected and timing advanced in order to reduce fuel consumption and emissions. The higher lift setting produces high torque and more power output.

Integrated dry-sump lubrication ensures a reliable supply of oil even when a sporty driving style is adopted. It also has additional cooling functions.

The oil tank is located in the engine, thereby eliminating the need for an external oil tank. Four oil pumps remove the oil from the cylinder heads directly into the oil sump. A fifth pump in the oil sump directly supplies the lubricating points in the engine.

To prevent foaming, the oil is channelled through cylinders known as swirlpots. In this way, optimum lubrication is guaranteed at all times.

To reduce drive losses and increase efficiency, an electronic on-demand oil pump is used. This means that the oil pump is operated at high power when there is high demand and at low power when there is low demand.

The result is an optimised oil supply appropriate to requirements, lower fuel consumption and reduced emissions.

Single-jet piston spray nozzles cool the piston crowns with oil from the main lubrication circuit – another detailed solution that helps to reduce the thermal load on the engine.

For the engine, these detailed solutions mean a consistent supply of oil regardless of gravitational loads, even in the most demanding track conditions.

DFI and VarioCam Plus enable a tremendous amount of power to be produced with comparatively low emissions, fuel consumption and noise. The same applies to our efficient cross-flow cooling system, as used in motorsport.


Chassis
As standard, the 911 Carrera GTS models are fitted with 19-inch RS Spyder wheels with centre spokes and rim well in a black painted finish.

The main feature of these forged aluminium alloy wheels is the central locking device – a clear reference to the world of motorsport. Compared with the conventional five-bolt wheel connection, it offers enhanced driving dynamics and performance thanks to the reduction in rotating masses.

Tyre Pressure Monitoring, available as an option, sends warnings to the on-board computer’s display screen in the event of a gradual or sudden loss of pressure.

Sport Chrono Package Plus is available as an option. It offers sportier tuning of the engine and chassis, and delivers greater driving pleasure as a result.

Key features include a digital and analogue stopwatch, the SPORT button, a performance display, a personal memory function in the Porsche Communication Management (PCM), and – in combination with Porsche Doppelkupplung (PDK) – the SPORT PLUS button, and an additional display in the steering wheel which informs the driver if the SPORT buttons and Launch Control have been activated.

Included as standard equipment, Porsche Active Suspension Management (PASM) is an electronic active damping system. It offers continuous adjustment of the damping force on each wheel, based on the current driving situation and your driving style. In addition, the body is 10 mm lower than that of the 911 Carrera models. For the 911 Carrera GTS Coupé models, it is possible to have the body lowered by 20 mm. This option includes the mechanically locking rear differential, which is already fitted as standard in the all-wheel drive models.

At the press of a button, the driver can select between two different modes: ‘Normal’, which is a blend of performance and comfort, and ‘Sport’, where the setup is much firmer. The balance between comfortable and uncompromisingly sporty is struck more effectively than with a conventional chassis. The PASM control unit evaluates the driving conditions and modifies the damping force on each of the wheels optimally in accordance with the selected mode.

Sensors monitor the movement of the vehicle body, for example, under heavy acceleration and braking or on uneven roads. The control unit tunes the dampers to the optimum hardness for the selected mode to reduce roll and pitch and to increase contact between each individual wheel and the road.

The independent front suspension of the 911 Carrera GTS models combines McPherson-type struts with longitudinal and transverse links and reinforced wheel bearings. Each front wheel is precisely located, ensuring excellent handling and directional stability.

At the rear axle, the body is 44 mm wider than that of the 911 Carrera S. This has made it possible to widen the track by 32 mm for improved dynamic performance and driving stability, and faster lateral acceleration when cornering.

The rear axle has a race derived multi-link suspension, following the LSA concept (Lightweight, Stable, Agile) for exceptional driving dynamics. Agility is further increased by lightweight struts with aluminium dampers.

This purposeful lightweight construction keeps the vehicle gross weight and the weight of the unsprung masses low, while the suspension itself allows even high-speed manoeuvres to be executed smoothly and safely.

Pitching of the body when pulling away and braking is minimal, as is body roll in corners. Tyre noise and vibrations are similarly reduced. Driving stability, on the other hand, is extremely high.

Safety
The front light units incorporate the direction indicators, the LED daytime running lights and position lights, which provide outstanding visibility and create an imposing look that is unmistakable even in the dark. LEDs are also used for the direction indicators, the taillights and brake lights, the additional brake light in the rear spoiler, and the rear fog light. LEDs offer several advantages. Importantly, they provide effective illumination and respond more quickly to driver input.

Bi-Xenon headlights with dynamic range control are fitted as standard. Their beams are around twice as bright as those of conventional halogen lamps. Light output is improved and the road illuminated more uniformly on both dipped and main beam, helping to minimise driver fatigue. A headlight cleaning function is also incorporated.

Available as an option, dynamic cornering lights offer particularly effective illumination of the road ahead, especially through bends. Sensors continuously monitor the speed, lateral acceleration and steering lock and, from these variables, calculate the course of the bend. This determines the angle of illumination for the dipped beam lights, up to a maximum of 15 degrees. On twisting roads, this means the course of the road and obstacles can be seen earlier by the driver.

Motorsport is the ultimate test of braking performance. On request, we can provide you with a brake system that has already had to cope with the harshest requirements of motorsport – a brake system fitted in the cars competing in the Porsche Mobil 1 Supercup, for example: the Porsche Ceramic Composite Brake (PCCB).

The ceramic discs have a diameter of 350 mm front and rear. The discs are made from a specially treated carbon-fibre compound that is silicated in a high-vacuum process at 1,700 °C. The resulting material is not only much harder than metal, it is also more resistant to heat.

Even at high temperatures, the thermal resistance of the PCCB discs ensures excellent dimensional stability. The ceramic material is totally resistant to corrosion and offers excellent acoustic damping properties.

The pads are mounted in six-piston monobloc aluminium fixed calipers at the front, with four-piston units at the rear. The resulting brake forces are both extremely high and remarkably consistent. The pedal response is fast and precise with only moderate input required.

PCCB enables shorter braking distances in even the toughest road and race conditions. Excellent fade resistance ensures greater balance when slowing from racetrack speeds.

The key advantage of PCCB is the total weight saving of approximately 50% over metal discs with similar construction and dimensions. As well as enhancing performance and fuel economy, this represents a major reduction in both the unsprung and rotating masses. This, of course, offers major benefits in terms of comfort and road holding on uneven road surfaces as well as general handling and agility.

Please note that circuit racing, trackday use and other forms of performance driving can significantly reduce the service life of even the most durable pads and discs. As with conventional high performance braking systems, we recommend that all brake components be professionally inspected and replaced where necessary after every track event.

Porsche brakes are widely renowned for their stability, performance and stopping power. They are designed to cope with extreme forces and offer an appropriately high level of safety.

The brakes on the 911 Carrera GTS models are equipped with red four-piston aluminium monobloc fixed calipers. This makes them tough but lightweight and enables a rapid response and release of the brake. The pedal travel is short and easy to control.

The brake discs have a diameter of 330 mm front and rear – for formidable braking performance.

Their cross-drilled design improves behaviour in wet conditions. The discs are also internally vented for better heat dispersal. Other features include a powerful nine-inch vacuum brake booster for reducing pedal effort, and integral air spoilers for enhanced air flow in the brake cooling ducts.

PSM, which comes as standard, is an automatic control system that stabilises the vehicle at the limits of dynamic driving performance. Sensors continuously monitor driving direction, speed, yaw velocity and lateral acceleration. Using this information, PSM computes the actual direction of motion. If this direction deviates from the desired course, PSM can, for example, initiate braking interventions targeted at individual wheels in order to stabilise the vehicle.

Under acceleration on wet or low-grip road surfaces, PSM improves traction using the ABD (automatic brake differential) and ASR (anti-slip regulation) functions. For a pure, active driving experience, PSM can be deactivated but it will automatically reactivate if necessary for safety.

PSM comes with two additional functions: precharging of the brake system, enabling the maximum braking power to be achieved much sooner; and brake assist, for maximum deceleration in a critical situation.

Those who speak in clear language want clear distinctions.

The Porsche Side Impact Protection System (POSIP), fitted as standard, consists of side impact protection beams in the doors and two side airbags on each side, namely a thorax airbag located in the side of each backrest and a head airbag incorporated within each door. Each airbag has an approximate volume of 8 litres, ensuring excellent protection in the event of side impact.

Additional safety features include the headrests which form an integral part of each seat, an energy absorbing steering column, three-point seat belts with height adjustment (Coupé models only), seat belt pre-tensioners and force limiters and energy absorbing elements in the dashboard.


Comfort
Time is precious, so you want to be able to see where everything is at a single glance. This is why the instruments of the 911 Carrera GTS models have been designed with sporty driving in mind.

The five circular instruments with dial faces in black give you all the important information you need efficiently and accurately.

The integrated on-board computer displays your average fuel consumption, speed and range until empty.

Alcantara* translates the exterior styling of the 911 Carrera GTS models into the interior. It is functional, hardwearing and proven on the racetrack. In a word, sporty. It is mainly used to cover features requiring extra protection against wear and tear: the gear and handbrake levers, the steering wheel rim, the door handles, the door storage compartment lids, the seat centres and, in the Cabriolet models, the centre of the rear bench seat. In conjunction with the optional leather interior package with black Alcantara, the glove compartment lid, the door centre panels and the lower section of the dashboard are also finished in Alcantara.

* Only in conjunction with standard interior package or leather interior package with black Alcantara.

Porsche Communication Management is the central information and communications system and comes as standard. It is both multifunctional and surprisingly easy to operate.

The main feature is the 6.5-inch touchscreen for intuitive control. You will find the display very clearly presented and a maximum of five list entries per page enable you to operate the unit quickly and safely. Alternatively, you can choose to operate the PCM using the rotary pushbutton on the right.

Radio functions include up to 42 memory presets and an FM dual tuner with RDS, which continuously scans in the background for the best signal. The integrated 6-disc CD/DVD drive supports MP3 formatted music files.

The BOSE® Surround Sound System, fitted as standard, has been matched to the specific interior acoustics of the 911 Carrera GTS models. A total of 13 loudspeakers (12 in the Cabriolet models), including an active subwoofer and central speaker, and a seven-channel digital amplifier with a rated output of 385 watts deliver an astounding sound experience.

During audio playback from audio or video DVDs, the system is able to make full use of the impressive sound spectrum of 5.1 digital recordings.

Five dedicated audio channels plus an effects channel for low frequencies deliver a sound that is as authentic as it is natural. The discrete 5.1 surround sound is balanced, lifelike and crystal clear. It’s a sound that’s as true to a live performance or cinematic experience as you can get.

Of course, you can still play traditional music sources such as CDs, either in stereo or in one of the surround modes generated by the patented BOSE® Centerpoint® technology. The algorithm of Centerpoint® II extracts precise and realistic sound from the stereo signal.

The SurroundStage® signal processing circuitry developed by BOSE® assigns each individual audio channel to a selected combination of loudspeakers and is therefore able to deliver an optimally balanced surround sound experience to all seat positions. The result is an outstanding level of audio quality, and a customised sound all made possible by the comprehensive selection of equaliser presets offered by the BOSE® Surround Sound System with dynamic loudness function and AudioPilot® Noise Compensation Technology.

Fitted as standard, the sports seats of the 911 Carrera GTS models are firmly padded. Higher side bolsters on the seat squab and backrest provide additional lateral support. The seat height and fore/aft position are adjusted manually, the backrest electrically.

Adaptive sports seats are available as an option, offering an extremely sporty experience and also a high level of comfort. They feature electric adjustment of fore/aft position, height and backrest angle and are equipped with lumbar support. The side bolsters on the seat squab and backrest are individually electrically adjustable, for enjoyable comfort on long journeys and tailor-made lateral support through bends or on the racetrack. The memory function supports the exterior mirrors and all driver’s seat positions, apart from the side bolsters.

For the ultimate sports experience, you could opt for sports bucket seats with a folding backrest, integral thorax airbag and manual fore/aft adjustment. The backrest shell is made from glass-/carbon-fibre-reinforced plastic and has a stylish carbon-weave finish. The backrest pivots are positioned high in the side bolsters to provide lateral support to the pelvic region, as you would expect from a race seat. The backrest folds for easy access to the storage space in the rear compartment.

As an option on the Carrera GTS coupé (standard on the Carrera GTS Cabriolet), all compatible seats – apart from sports bucket seats – can be equipped with two-level seat heating. Seats are heated in the seat squab, backrest and side bolsters.

* Child seats must not be used with the sports bucket seats.

The three-spoke SportDesign steering wheel was developed specifically for the 911 Carrera GTS models and is fitted as standard. It offers 40 mm of adjustment for both height and reach and, thanks to its grip mouldings, it’s in safe hands – even on the sportiest of drives. Other features include an integral full-size airbag, a high-grip steering wheel rim and outstanding ergonomics.

In conjunction with the optional Porsche Doppelkupplung (PDK), the steering wheel is equipped with two gearshift paddles.

The paddles are made from a strong alloy and are ergonomically located behind the right and left steering wheel spokes. Pull the right-hand paddle and the PDK shifts up. Pull the left-hand paddle and the PDK shifts down.

When PDK is combined with the optional Sport Chrono Package Plus, the steering wheel also features an additional display in the left- and right-hand spokes. It tells you whether the SPORT, SPORT PLUS and Launch Control functions are activated.

Colours
A wide range of colours offers the option of giving your 911 an even more personalised character. The selection of standard or special paint colours, the interior and leather finishes provide a pronounced high degree of personalisation. There are no limits to your creativity – anything is possible.
