Dynamic cornering lightsEdit

Available as an option for the Cayman models are Bi-Xenon headlights including dynamic cornering lights and LED daytime running lights. Bi-Xenon headlights are around twice as powerful as halogen headlights so they offer improved visibility and they illuminate the road more evenly. In fact, they are so effective that fog lights are no longer necessary. A headlight cleaning system is built-in.

Dynamic cornering lights offer particularly effective illumination of the road ahead, particularly 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 the dynamic cornering lights, with the lights able to swivel towards the inside of the bend up to a limit of 15 degrees, even with main beam switched on.

Porsche Ceramic Composite BrakeEdit

On request, we can equip your Cayman S with a brake system that has already had to cope with the harshest requirements of motorsport: the Porsche Ceramic Composite Brake (PCCB). The ceramic brake discs have a diameter of 350 mm front and rear– for extremely powerful braking.

The brake discs are formed from a specially treated carbon-fibre compound that is silicated in a high-vacuum process at approximately 1,700 °C. Not only are the resulting discs much harder than standard discs, they are more resistant to heat. The low thermal expansion of the brake discs prevents deformation under heavy braking. Furthermore, the ceramic brake discs are totally resistant to corrosion and offer more favourable noise-damping properties.

Six-piston aluminium monobloc fixed calipers on the front axle and four-piston units at the rear provide a high and constant brake pressure. The pedal response is fast and precise with only moderate input required.

All the necessary ingredients are there for a short braking distance, even in the toughest conditions. Moreover, safety under braking at high speeds is increased thanks to the excellent fade resistance of PCCB.

The key advantage of PCCB is that the brake discs are approximately 50% lighter than standard discs of similar design and size. A factor that helps to reduce unsprung and rotating masses on the vehicle. 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, trackday use and other forms of performance driving can significantly reduce the service life of even the most durable brake pads and discs. We recommend that all brake components be professionally inspected and replaced where necessary after every track event.

AirbagsEdit

Each of the full-size airbags is inflated in two stages, depending on the severity of an accident. In less serious accidents, the airbags are only partially inflated, thereby minimising discomfort for the occupants. Also fitted as standard is Porsche Side Impact Protection (POSIP).

It comprises side impact protection elements in the doors and two airbags on each side. An integral thorax airbag is located in the seat backrests, while the door panels each contain a head airbag. With each having a volume of approximately 8 litres, these airbags offer excellent protection in the event of a side impact.

Other passive safety features include head restraints integrated into the seat backrests, an energy absorbing steering column, three-point seat belts, front seat-belt pretensioners and force limiters, energy-absorbing elements in the dashboard and flame-resistant materials throughout the interior.

Porsche Stability ManagementEdit

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 initiates 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, giving an agile response. When ‘Sport’ mode is selected on the optional Sport Chrono Packages, the PSM intervention threshold is raised to enable greater driver involvement – particularly at speeds of up to approximately 70 km/h (45 mph). The integrated ABS can further reduce the braking distance. For an even sportier drive, PSM can be deactivated. However, it is automatically reactivated for your safety if either of the front wheels (in ‘Sport’ mode, both of the front wheels) requires ABS assistance. ABD remains permanently active. PSM has been enhanced and now includes two additional functions: precharging of the brake system, and brake assist. If you suddenly release the accelerator pedal, PSM automatically readies the braking system. With the braking system having been precharged, the brake pads are already in light contact with the brake discs. Maximum braking power is therefore achieved much sooner. When sudden braking is detected, the brake assist function applies maximum brake pressure to all four wheels.

Braking systemEdit

The acceleration of the Cayman models is impressive. Even more impressive, perhaps, is the vehicle’s maximum braking power, which comfortably tames the power of the engine.

Four-piston aluminium monobloc brake calipers are fitted front and rear. Offering excellent rigidity, they are compact and save on weight. Their superior responsiveness, for fast and sensitive braking, sets them apart. A brake booster provides assistance, reducing pedal effort whilst maintaining a powerful braking effect.

A special ventilation system, whereby the entire wheel brake is supplied with cooling air by openings in the front end and special channelling systems, increases the stability of the brakes during heavy use.

For the Cayman models, the braking system has been modified to cope with the increased engine power. Just like the Cayman S, the front axle of the Cayman features internally vented brake discs with a diameter of 318 mm. On both models, 299 mm brake discs are fitted to the rear axle. The brake pads have also been optimised for improved braking performance. The rear brake discs of the Cayman S are 4 mm thicker than those of the Cayman, which increases stability under load even further. To distinguish them visually, the brake calipers on the Cayman have a black anodised finish while those on the Cayman S are painted red.

For reduced weight, optimum braking in the wet and improved cooling, the brake discs on both models are cross-drilled.

For the Cayman S, the Porsche Ceramic Composite Brake (PCCB) is available as an option.

Passive SafetyEdit

The system of longitudinal and transverse members at the front of the vehicle distributes the forces exerted onto the bodyshell in the event of an impact and minimises deformation of the passenger cell. Our patented bodywork structure with a rigid bulkhead cross member made of ultra high-strength steel absorbs the forces introduced into the system of longitudinal members which prevents deformation of the footwell. The reinforced doors contribute to the overall rigidity of the car. The forces exerted in a frontal collision are transmitted into the side structure along a higher load path, which improves the deformation characteristics of the passenger cell even further.

Anti-theft protectionEdit

Both models are equipped with an immobiliser with in-key transponder. In addition, the Cayman S has an alarm system with contact-sensitive exterior protection as standard (optional for the Cayman). It is activated and deactivated by the remote control integrated in the ignition key, which is also used to lock and unlock the doors. Radar-based interior surveillance is available as an option for both models.

In conjunction with the alarm system, this optional preparation enables future installation of a vehicle tracking system available from Porsche Tequipment. It makes it possible to locate a stolen vehicle across most of the countries of Europe. The package includes a special wiring loom and a higher-capacity battery. A tilt sensor for the alarm system is included.

EnvironmentEdit



Exhaust emission controlEdit

Both engines comply with stringent emission standards, including EU5 in Europe and LEV II / ULEV in the USA. Vehicles manufactured by Porsche demonstrate that even high-performance sportscars can achieve moderate emission values in their respective category. In short, the Cayman is not only extremely sporty, it is also very clean.

This attribute is achieved by means of a two-stage cascade-type catalytic converter which comprises two monolith substrates on each of the twin exhaust tracts. These specially coated substrates contain ultra-fine honeycomb channels in which pollutants are converted as exhaust gas passes through. The stereo lambda control circuitry controls and monitors each cylinder bank separately, while another lambda sensor on each cylinder bank monitors pollutant conversion in the respective catalytic converter.*

FuelEdit

The Cayman models are already designed to operate on fuels with an ethanol content of up to 10%. Ethanol has a positive impact on the CO2 balance since the plants cultivated for the production of this biofuel also absorb CO2 from the atmosphere.

The active carbon filter and a special coating on the fuel tank reduce the amount of hydrocarbons released from the fuel system. All fuel lines are made of aluminium, while vapour-carrying lines are made from multi-layered plastic.

MaintenanceEdit

Long service intervals offer clear advantages. For you: lower costs and saved time. For the environment: the use of fewer consumables and replacement parts. For full details of service intervals, please refer to the separate price list.

• ==Design==

The design of the Cayman models is befitting of their distinctive, sporty character. Edit

• Their performance potential is obvious at first sight, for these are true specimens of force and athleticism. Individual styling features help to define both vehicles so impressively.
• A constant interaction of convex and concave curves. A certain style, like no other. Immediately, the front displays the kind of character that you expect to find in the Cayman models. The front end has been restyled with enlarged air intakes that hint at the performance within.
• The contouring of the front apron gives the car an even more purposeful appearance. The front spoiler lip has been enlarged, further reducing lift at the front axle.
• The front wings with their integrated headlights give the Cayman models a distinctively sporty look.
• Both models are equipped as standard with halogen headlights, LED position lights and front fog lights integrated into the outer air intakes. Bi-Xenon headlights with dynamic cornering lights, including LED daytime running lights, are available on request.
• Follow the car’s clean lines along the side towards the rear, past the newly styled and enlarged exterior mirrors, where the impressive design continues. The styling is emphasised by the distinctly pronounced curves of the front and rear wings and the shape of the doors.
• Typically for a coupé, there is a gradual, flowing transition from the A-pillar to the rear. The sharper contour of the side skirts directs the air stream down to the side air intakes which are designed to facilitate considerable through-flow. The rear section of the side windows curves dynamically upwards. Extending beyond the side windows are two additional lines that direct attention towards the rear end. One of these lines continues to frame the large rear screen.
• The second line continues its rearward path to the LED taillight module. The elegant, extendable rear wing further reduces lift at the rear axle.
• Below, you cannot miss the visible hallmark of the characteristic Porsche sound: the stainless steel tailpipe – twin tailpipe on the Cayman S – integrated into the rear end.
• The unmistakable styling of the Cayman models is complemented by the wheel design. The Cayman is fitted with 17-inch wheels as standard, the Cayman S with 18-inch wheels. A 19-inch option is available for both models.
• The result of all of these measures? A unique appearance and refined aerodynamics with a low drag coefficient of only 0.29.
• The Cayman models. Even more sophisticated, even more dynamic, and when it comes to style, they trust in only one direction: their own.
