The 3.4-litre engine of the 911 Carrera models demonstrates, therefore, that performance and efficiency need not be mutually exclusive. Rather, the downsized engine capacity and increased maximum torque are the intelligent basis by which power output can be increased in an environmentally acceptable and sustainable way. Fuel consumption and CO2 emissions have been reduced by up to 16 % compared with the previous model. In their search for improved efficiency, our engineers analysed an extensive series of engine components. Answers were found, including rapid heating of the engine and gearbox to normal operating temperature after an engine start by the thermal management system, improved air induction and extremely effective direct fuel injection (DFI).
he thermal management system regulates the temperature in the engine and gearbox through the intelligent manipulation of heat flow.In this way, the engine and gearbox reach their optimum operating temperature sooner. As a result, fuel consumption is reduced through increased combustion efficiency and lubrication performance. The 911 Carrera models are also equipped as standard with fuel-saving electrical system recuperation technology. The vehicle battery is recharged by the alternator predominantly under braking. Under acceleration, on the other hand, the power draw of the alternator is limited to increase the engine output available for driving. The electrical systems are supplied by the electrical energy stored during the recharging process.
Pure, direct, precise. Short shift movements and an optimum transition from one gear to the next. That's exactly what you would expect of a Porsche manual gearbox. What you might not have expected is a 7-speed manual gearbox that combines a high level of sporty performance with an equally high level of efficiency and offers extra comfort for longer journeys. It's an exceptional innovation, and not only in the sports car segment. The design of this manual gearbox is based in principle on that of Porsche Doppelkupplung (PDK). Gears 1 to 6 have a sports ratio and top speed is reached in 6th gear. The additional 7th gear, however, has a long ratio, which reduces torque and helps to reduce fuel consumption. Lower engine revs at fast driving speeds also ensure a high level of comfort on long stretches of road. In addition, a gear indicator in the rev counter reminds you which gear has been selected. The upshift indicator in the instrument cluster helps you actively conserve fuel.
Available as an option for all 911 Carrera models is 7-speed PDK, featuring manual and automatic modes. It facilitates extremely fast gear changes with no interruption in the flow of power, whilst at the same time improving acceleration and fuel efficiency. The first six gears are particularly sporty, with top speed being reached in 6th gear. 7th gear has a long ratio and reduces the revs — for lower consumption. PDK is essentially two gearboxes in one and thus requires two clutches. This double-clutch arrangement provides an alternating, non-positive connection between the two half gearboxes and the engine by means of two separate input shafts. The flow of power from the engine is 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, one clutch simply opens and the other closes at the same time, enabling gear changes to take place within milliseconds. The effect is instant. Driving feels even sportier and more dynamic, and agility is increased. Depending on the gearshift programme (SPORT button activated or deactivated), the gear change is optimised for comfort or for sporty driving.
The resonance intake system increases the intake volume by exploiting the fact that air oscillates as it passes through the intake manifold. The system can adjust to engine speed. Benefits of this include higher torque at low engine speeds and a flatter torque curve. The 911 Carrera S models operate a two-stage system. The entire intake system is made from lightweight plastic. In the 911 Carrera models, the resonator volume of the air filter housing varies with engine speed to bring added character to the engine sound, which becomes much more powerful at higher rpm.
DFI delivers fuel directly into the combustion chamber with millisecond precision. The spray and cone angles of the multi-hole injectors have been optimised for torque, power output, fuel consumption, emissions and efficient combustion. With direct injection, the engine management system regulates injection timing individually for each cylinder as well as the injection rate for each cylinder bank. This improves the combustion process and fuel economy. For faster heating of the catalytic converters after a cold start and optimum torque in the upper load range, up to three injection pulses take place per combustion cycle. DFI improves the internal cooling of the combustion chamber by having the mixture prepared directly in the cylinder. This allows for a higher compression ratio, which helps to deliver more output at the same time as enhanced engine efficiency. Injection is regulated by the electronic engine management system and emissions are monitored by the Lambda sensors.
The 911 Carrera models are equipped as standard with Bi-Xenon headlights including a headlight cleaning system and dynamic range control. The LED front light units incorporate indicators, daytime running lights and position lights. Automatic headlight activation is also included as standard. Cutting edge LED technology is also used for the taillights, the high-level third brake light, the license plate illumination, the rear direction indicators, the rear fog light and — on all-wheel-drive models — the rear light strip. LEDs provide better illumination and respond more quickly to driver input.
The electrically adjustable slide/tilt sunroof is available as an option for all 911 Carrera Coupe© models. It opens outwards so that it does not interfere with headroom. Another advantage of this special design is the large aperture for increased driving pleasure under the open sky. The two-position net-type wind deflector protects against draught and further reduces wind noise.
Our materials are high-quality with a sporty character. The steering wheel rim, door pulls and armrests are in leather, for instance. Alcantara has proven its worth in motorsport and is used as standard for the roof lining of the Coupe models. In addition to the choice of Black, Platinum Grey, Luxor Beige and Yachting Blue for the interior, there is a wide range of other personalisation options available, including two-tone color combinations or special colors and materials such as carbon, aluminum or high-quality wood. Engineering that takes you forward: standard Porsche Communication Management (PCM) with navigation module and a high-resolution 7-inch color touchscreen. PCM is your control centre for audio, navigation and communication functions.
The instrument cluster with a high-resolution 4.6-inch TFT color screen provides you with a continuous stream of data from the on-board computer, such as trip mileage, journey time or average fuel consumption. It also displays the navigation system map, delivers various warnings, including alerts from the Tire Pressure Monitoring (TPM) system and, in 911 Carrera 4 models, tells you the current front/rear axle torque distribution. You can also use it to personalise various in-car settings.
The optional BOSE® Surround Sound System was specially developed for the 911 and is therefore perfectly tuned to the car's specific interior acoustics. It has a total output of 445 watts and comprises eight amplifier channels, 12 loudspeakers and a patented integral 100-watt active subwoofer. The combined effect is a balanced acoustic pattern that transforms your 911 into a fast-moving concert hall. In combination with the Porsche Communication Management (PCM) system, the BOSE® Surround Sound System enables audio playback of DVDs and is thus able to make full use of the impressive sound spectrum of 5.1 digital recordings. Of course, you can still play other audio sources, such as CDs and MP3s, in stereo or, at the push of a button, in one of the virtual surround modes generated by BOSE® Centerpoint® 2.
The optional quadband GSM telephone module offers convenience and excellent reception. With a SIM inserted directly into the integral SIM card reader of the PCM system, calls can be made using the hands-free facility. For even more convenience, the Bluetooth® capability of a mobile phone can be used to make calls via the SIM Access Profile (SAP). Once the connection has been established automatically, the mobile phone's aerial is switched off to conserve battery charge and the phone operates via the car aerial. Depending on the mobile phone model, this gives access not only to the numbers on the SIM card, but also to the phone's internal memory. Depending on the phone, it can also be controlled using PCM, the optional multifunction steering wheel or the optional voice control system, without it ever leaving your pocket.
The 911 Carrera models offer advanced airbag technology in the form of full-size driver and front passenger airbags, which are inflated in two stages depending on the severity and type of accident (e.g. frontal or offset frontal). In less serious accidents, the airbags are only partially inflated, thereby minimising discomfort to the occupants. In addition to the central airbag control unit on the transmission tunnel, a pair of impact sensors are located near the headlights. This allows a crash to be detected and evaluated not just sooner, but with even greater accuracy.
The innovative bodyshell of the 911 fulfills two structural design requirements: first, excellent driving dynamics due to the body's extremely high rigidity; second, a low vehicle weight primarily as a result of the intelligent lightweight construction. To meet the second requirement, we employed state-of-the-art techniques for combining various materials in order to utilise specific material properties exactly where they are needed. For the bodyshell, therefore, we used very thin, but nevertheless extremely rigid, sheets of steel. Aluminum and magnesium were used extensively in areas such as the roof, underbody, front end, doors, rear wings and engine compartment and luggage compartment lids. Magnesium, which is a particularly lightweight material, was also selected for the cockpit and centre console support beam and, in the Cabriolet models, the hood shell elements.
Another crucial piece of the Porsche identity is the brakes. We value them as highly as we do our engines and chassis. They set standards for deceleration and stability, and give the driver the reassurance needed to push the car to the limits of its performance. The 911 Carrera base models are fitted front and rear with anodised black four-piston aluminum monobloc fixed calipers. All brake discs have a diameter of 330 mm. On all models, the brake calipers have an enclosed monobloc construction. This makes them tougher but lighter and enables a more rapid response and release of the brake even under extreme loads. The pedal travel is short and the biting point precise. The brake discs are cross-drilled for better performance in the wet.
