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 anodized black four-piston aluminum monobloc fixed calipers. All brake discs have a diameter of 13 inches (330 mm).

On the S models, we have fitted larger brakes and more brake pistons to cope with the higher engine power of these models. Consequently, they feature red six-piston monobloc aluminum fixed brake calipers at the front and four-piston aluminum monobloc fixed calipers at the rear. The brake disc diameter is 13.4 inches (340 mm) at the front and 13 inches (330 mm) at the rear. The

results are enhanced braking performance and stability.

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.

Other benefits of the standard braking system include the anti-lock braking system (ABS), designed to keep deceleration constant. Pedal effort is reduced and braking response improved by an 8-/9-inch tandem vacuum brake booster. In the S models, brake disc cooling is further enhanced by modified air spoilers.

From the start, Porsche has been synonymous with motorsport. Ever since 1948, when we found our identity on the racetrack, we have taken the experience we have gained and applied it to the road. The optional Porsche Ceramic Composite Brake (PCCB) is a fine example. This brake system has already had to cope with the harshest requirements of motor racing and is fitted in cars that compete in demanding events such as the Porsche Mobil 1 Supercup.

The cross-drilled PCCB ceramic brake discs for the 911 Carrera have a diameter of 13.8 inches (350 mm) front and rear for even more formidable braking performance.

The use of six-piston aluminum monobloc brake calipers on the front axle and four-piston units at the rear – all finished in yellow – ensures extremely high brake forces which, crucially, are

exceptionally consistent.

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 extremely low weight of the ceramic brake discs, which are approximately 50% lighter than standard discs of similar design and size. As well as enhancing performance and fuel economy, this represents a major reduction in unsprung and rotating masses. The consequence of this is better road holding and increased comfort, particularly on uneven roads, as well as greater agility and improved handling.

Please note that circuit racing, track day use and other forms of performance driving can significantly reduce the service life of even the most durable brake 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.

As standard, the 911 models are equipped with enhanced Porsche Stability Management (PSM), which maintains stability even at the limits of dynamic driving performance. Sensors continuously monitor the direction, speed, yaw velocity and lateral acceleration of the car. Using this information, PSM is able to calculate the actual direction of travel at any given moment. If the car begins to oversteer or understeer, PSM applies selective braking on individual wheels to restore stability.

Under acceleration on wet or low-grip road surfaces, PSM improves traction using the automatic brake differential (ABD) and anti-slip regulation (ASR). When the SPORT PLUS mode of the optional Sport Chrono Package is selected, the PSM threshold is raised to allow a sportier driving style.

For an even more dynamic experience, you always have the option to deactivate PSM. It is automatically reactivated, for your safety, only if you brake harder and either of the front wheels (in SPORT PLUS mode, both of the front wheels) requires ABS assistance. ABS and ABD, however, remain active at all times.

PSM therefore offers a high level of driving stability and safety combined with extraordinary agility. It’s an apparent contradiction in terms, but an intrinsic part of the Porsche identity.

The 911 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 minimizing 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 far sooner and with considerably greater accuracy.

Coupe or Cabriolet, the 911 models are equipped as standard with the Porsche Side Impact Protection System (POSIP). It comprises side impact protection elements in the doors and two airbags on each side. An integral thorax airbag is located in each seat side bolster, while the door panels each contain an upwards-inflating head airbag. Each thorax airbag has a volume of 2.6 gallons (10 liters) and each head airbag 3.9 gallons (15 liters), ensuring excellent protection in the event of a side impact.

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 vehicle weight saving of up to 143 lbs 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 utilize 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 center console support

beam and, in the Cabriolet models, the hood shell elements. Such material efficiency is key to reducing the overall weight and, as a result, fuel consumption of the vehicle.

For the driver, this intelligent blend of materials reduces the weight of the vehicle and offers a high level of comfort thanks to excellent vibration-damping characteristics and particularly high composite rigidity, an increase in dynamic torsional stiffness of up to 25% compared with that of the previous model, and even sportier handling despite a further improvement in the weight to power ratio.

The longer wheelbase improves comfort as well as straight-line accuracy and driving stability at high speeds and in fast corners.

All 911 Carrera models are equipped as standard with an immobilizer with in-key transponder and an alarm system with radar-based interior surveillance. The system secures the doors, luggage compartment, passenger compartment and ignition lock.
