Foreword

The Cayman was launched in November 2005 as an S version and immediately


set new standards as a Porsche mid-engine coupé. The mid-mounted flat engine
is not just one of the main unique selling points of the Cayman. Its agility and
pure sportiness also predestined it right from the start as the benchmark in the
2-seater sports coupé segment. Its performance increased continuously over the
years as a result of further development and the Cayman evolved into one of the
best vehicles in the Sports Car segment in terms of driving dynamics alongside
the 911 Carrera. Its unique design fascinated its target group from the very
beginning. The new Cayman embraces the success factors of its predecessor and
continues to undergo significant development.

0_01_13

A totally redesigned platform with an almost completely new technology package


was used for the Cayman. Featuring the most up-to-date and unmistakeable
Porsche present and future design features, the new Cayman will contribute to
shaping the Porsche Sports Car range in the long term.
2014 Cayman Section 1 2/21/13 10:33 AM Page v2

A unique new design, mid-engine driving dynamics and very high performance as
well as enhanced day-to-day usability set the new Cayman apart. The objective of
further development was not just to significantly improve the typical Porsche
product characteristics, but also to give the car a more unique appearance.
The new body design, which makes the vehicle lighter and more rigid than its
predecessor, achieves top marks when it comes to driving dynamics and
performance. What’s more, it does so with lower fuel consumption and significantly
reduced CO2 emissions.

1 Engine Cayman S

1.1 General
Two different engines are available for the Cayman in model year 2014.

• The standard models come with an engine where the displacement has been
reduced to 2.7 liters from the previous 2.9 liters, while the power has been
increased once more (from 265 to 275 hp). This was possible through the
Engine
1
use of direct fuel injection and by increasing the nominal engine speed from
6,400 rpm to 6,700 rpm.
• The displacement of 3.4 liters has been retained for the S models, although
here too the power has been increased from 320 to 325 hp by increasing
the nominal engine speed.

3 Power transmission Cayman S

3.1 General
The transmission is crucial both for driving performance as well as comfort and fuel
consumption. The new Cayman models are equipped with a 6-speed manual
transmission as standard. The gear stepping is optimally designed for the engine
characteristics of the new Cayman models for good acceleration as well as fuel
consumption and comfort benefits. When driving on highways in particular, low
Power transmission
3
engine speeds reduce the noise level in the passenger compartment. The gear
recommendation in the instrument cluster helps to ensure optimal fuel economy.
In addition, the new gear indicator in the tachometer shows which gear is engaged.
The elevated center console and the driver’s seat position ensure that there is only
a short distance between the steering wheel and gear lever, creating a sporty
driving feeling and guarantees fast and reliable gearshifts.

3b.2 Shift mechanism

Power transmission

cardiagn.com
3_03_12

The G81.00 and G81.20 are manual transmissions with six forward gears and one
reverse gear. Shifting is performed via two cable mechanisms. One cable is used
for selection, the other for shifting. Shifting follows an ‘H’ shift pattern.

3b.3 Intermediate throttle application during deceleration


downshifts
The model year 2013 Cayman models use an intermediate throttle application
function in conjunction with a manual transmission. The intermediate throttle
application, which is controlled electronically via the electronic throttle, allows the
engine to rev up to the speed of the lower engaged gear with maximum agility and
precision. This produces a sporty sound in the passenger compartment.

Function
The speed of the input shaft is detected via a sensor on the transmission, while the
speed of the transmission output shaft is determined based on the vehicle speed.
The gear ratio and therefore the engaged gear are calculated in the DME control
unit based on the ratio of the two speeds.

If a gear change is initiated at this point, the relevant gear is speeded up or slowed
down during the synchronization process (clutch is depressed). The resulting
change in engine speed indicates whether an upshift or downshift is taking place.
The intermediate throttle application function is activated during downshifting.
The increase in engine speed (intermediate throttle application) is dependent on
whether the Sport or Sport Plus button is activated.

14
Cayman
Cayman S

The advantages of this function are as follows:


More comfortable gear changes; no vibrations are produced in the drivetrain during
clutch engagement.
• The throttle applications provide the driver with immediate feedback
regarding the downshift.
• No deceleration torque at the rear axle during clutch engagement. The
Power transmission
3
oversteering tendency during extreme driving manoeuvers (e. g. on low grip
surfaces) is greatly reduced.
• Clutch wear is reduced.
• The gear indicator in the instrument cluster responds much faster and is
always active.
• The intermediate throttle application function is also deactivated using the
PSM Off switch.

3b.4 Summary of additional modifications
The additional modifications in the area of power transmission are identical to the
modifications to the model year 2013 Boxster and Boxster S. An overview of the
modifications is provided again here:
• Triple cone synchronizers with carbon coatings for synchronization of 1st and
2nd gear
• Thermal management on the transmission with oil pump
• Temperature sensor on the transmission for thermal management
• Neutral detection sensor on the transmission for Start Stop system

4.1 General
The design used for the chassis makes a decisive contribution to the handling
characteristics of a vehicle; on a mid-engine vehicle like the Cayman, the handling
characteristics are further improved by the favorable weight distribution. This made
it possible to further consolidate the leading position of the Cayman in the areas of
driving dynamics and agility while at the same time placing particular importance on

Longer wheelbase and wider track at the front


Extending the wheelbase by 60 mm results in even greater driving stability,
particularly at high longitudinal and cornering speeds. The wider track width at the
front ensures vehicle stability during fast cornering and in the event of destabilizing
effects, which translates to a high level of safety and driving comfort as well as fast
lap times.

5 Body Cayman S

The main focus in the development of the new Cayman was also on reducing weight
while at the same time enhancing driving dynamics. In order to reduce weight,
numerous modifications were made to the body. These measures are described in
detail in this chapter.
Body
5
5.1 General
The body of the new Cayman is now around 14% lighter than its predecessor. As a
result, the Cayman body, including add-on parts, weighs only 631 lbs (286 kg). The
body of the previous model was made entirely of steel and weighed 732 lbs (332
kg) including add-on parts.

The following measures were implemented in order to realise these objectives:

cardiagn.com
• Consistent lightweight construction through the use of aluminum as well as
high-strength and ultra high-strength steels
• Platform strategy: Use of the body front section and middle floor assemblies
from the 991 Carrera model line

5_01_13

25
Cayman
Cayman S

The consistent enhancement of the lightweight body also makes a significant

Body
5 contribution to safety. In the event of a crash, the forces that occur are distributed
to longitudinal and cross member structures in the body front section and rear end
in a predefined manner. The multi-phase steels used ensure high strength, clear
deformability and optimum energy absorption. Reinforcements made from ultra
high-strength, hot-formed steels also protect occupants in the event of side impact.
It has been possible to increase the body’s dynamic rigidity by 11% in terms of
torsional rigidity and 14% in terms of flexural strength compared to the previous
model. Static torsional rigidity has even been increased by 40% (see Figure
5_02_13 and 5_03_13).

These ultra high-strength steels surround the passenger cell like a cage and with
their extreme dimensional stability play an important role in maintaining the integrity

cardiagn.com
of the cabin and therefore protecting the occupants. Of course, the new Cayman
models also meet the requirements with regard to pedestrian protection. The optimized

aluminum and steel hinges achieved a weight saving of 15 lbs (7 kg here).

Since there is a high corrosion potential when steel is joined with aluminum, it was
necessary to make use of the latest joining techniques in manufacture of the body.
The following main joining techniques were used:

Torsional forces
Joining technique Quantity/Length

Punch rivets 1,559

Flow-drill screws 143

Bending forces Clinch joints 407

MAG/MIG welding length 7.8 m

Resistance spots 1,953

Cayman
Cayman S

Contact corrosion
If the corrosion protection is defective, joints between aluminum and steel can be
subject to much higher corrosion rates than purely aluminum or steel joints. For this
reason, it is important to ensure in production and in AfterSales that these joints are
produced in accordance with the highest quality standards and that these standards
are observed on every body. Aluminum has a passivating oxide layer on the surface
Body
5
that protects the alloy underneath against environmental influences. That is why an
unpainted aluminum component normally does not corrode.

However, contact corrosion will occur if contact occurs between aluminum and
a metal that has a positive potential in the table of standard electrode potentials in
comparison with aluminum and if an electrolyte such as saline water is present at
this location.

This contact corrosion can be prevented only if measures are taken to prevent the
flow of current (caused by the potential difference) between the two metals. In the
simplest case, this is achieved by painting the surfaces. However, there is a high
risk of contact corrosion in this case if there is even the tiniest paint damage, even
damage that is invisible to the eye. The greater the potential difference, the greater
the risk. Since aluminum is usually the baser metal, it will be attacked and in
extreme cases decomposed.

Resistance to contact corrosion is ensured by joining the components by way of


non-thermal processes using coated punched rivets and special screws in combi-
nation with adhesive bonding. The basis for corrosion protection at corrosion
susceptible aluminum/steel joints is provided by the use of adhesive bonds on the
unpainted bodyshell of the Cayman. These adhesive bonds provide large-area
insulation of the aluminum/steel components, thereby preventing corrosion
processes at the contact point. As a further measure, all aluminum/steel joints are
either sealed with PVC or preserved with wax following electrophoretic dip priming.

The following corrosion protection measures are implemented on the Cayman:


• Coating of all steel screws and fasteners such as punched rivets and high-
strength blind rivets used in the Service organization
• Galvanisation of all steel sheet components (zinc and aluminum have a lower
potential difference than steel and aluminum)
• Electrochemical insulation by adhesive sealing of aluminum/steel joints

Detailed overview of steel components

Body
5 Different steel grades are used depending on the application and purpose of the
component. The steel grades used can be categorized in four groups as follows:
• Deep-drawing steel
• High-strength steel (micro-alloyed steel)
• Higher-strength steel (multi-phase steels)
• Ultra-high-strength steel (heat-formed, boron-alloyed)

Repair concept
Increasingly stringent safety requirements demand that materials with the highest
strength characteristics are used in the Cayman. These ultra-high-strength steels
are used for safety components such as A- and B-pillars and door sills. This material
poses new challenges for body repairs because its extremely high strength
significantly impairs its reshapability, weldability and machinability. In principle, such
Body
5
repairs correspond to the procedure for purely steel vehicles.

However, special precautions must be taken due to the risk of contact corrosion of
aluminum body parts. Grinding dust from the steel parts and particularly flying
sparks produced by cutting or welding work must not be allowed to fall on aluminum
parts. This also applies for painted aluminum parts. The paint may be damaged by
red-hot steel parts and the steel particles may come into contact with aluminum

cardiagn.com
body part, which can lead to contact corrosion on the undamaged aluminum body.

For this reason, the entire body must be carefully protected when performing steel
repairs. This is done by using corresponding covering tarps and masking. In
addition, cutting work must be performed only as machining operations with the
body saw. Where grinding work is unavoidable, grinding discs must be used that
produce either no or only minimum sparks. When performing welding work, a spot
welder must be used where possible, since this produces less welding material
spatter during the welding process.

If components close to the steel assemblies are replaced, the repair and spare

5 parts concept must be designed so that sectional repairs can be carried out here.
The side panels are divided into three sections (see Figure 5_10_13), which can be
welded during repairs after removing the damaged areas.

5_10_13

If the bodyshell structure is damaged, i.e. if deformation on the cast aluminum parts
exceeds the specified tolerance of +/- 2 mm, these parts must be replaced. The
complete rear end is available as a spare part for this purpose, for example (see
Fig. 5_11_13).

The different colors identify the individual
components of the rear-end spare part.

Extreme care must be taken when joining steel and aluminum components in order
to rule out the possibility of contact corrosion at a later point in time. Two-
component body adhesive Betamate 2096 and high-strength rivets or flow-drill
screws are used in the joint areas. As in series production, an insulation layer is
produced here between the two materials that prevents contact corrosion.

5.3 Outer roof panel
Laser soldering is used for the first time also for Sports Cars. In order to achieve a
seamless joint, and at the same time a high degree of rigidity in the roof area, the
outer roof panel is joined to the bodyshell during production using the laser
soldering joining technique. The next illustration (Fig. 5_12_13) shows a cross-
section of the roof pillar and the soldered outer roof panel.

During repairs, the roof is cut out and bonded into place using the adhesive Terokal
5045, following the familiar procedure for the Cayenne models.

5.4 Aerodynamics

Body
5 The new Cayman models also feature improved aerodynamics. Despite the fact that
the cooling system was adapted to meet the requirements of the increased engine
and braking power, it was still possible to retain the excellent drag coefficient of
0.30 provided by its predecessor.

The new rear spoiler in wing design has a larger area and comes as a separate
component. This allows optimum adaptation of the vehicle aerodynamics. The result
is reduced lift at the front and rear axles. The tail lights are also designed as a
continuation of the spoiler and this even improves the lift coefficients. Furthermore,
the underbody is fully panelled, which also helps to improve the drag coefficient.

5.5 Lids and flaps


The doors, lids and fenders on the new Cayman models weigh 32% less overall than
on the previous models. This corresponds to a reduction from 159 lbs to 108 lbs
(72 kg to 49 kg).

The front lid is of the same design as the Boxster models. In terms of production, it
comprises 6 individual components and is made completely of aluminum. The lid
weighs approx. 16.5 lbs (7.5 kg).

allowed weight savings of around 51% in comparison with the predecessor model
(from 30 lbs to 14.5 lbs (13.5 kg to 6.6 kg), with torsional rigidity increased by
146%.

5.6 Doors

Body
5 The doors are of the same design as those used on the Boxster models. The inner
door frame is made of die-cast aluminum, while the window channel reinforcement is
made of extruded aluminum profile. The outer door panel is made of aluminum. In
order to increase safety in the event of a side collision impact, reinforcement
elements made of ultra high-strength steel were also incorporated into the doors.
Overall, measures implemented on the lids, fenders and doors have resulted in
a weight saving of approx. 51 lbs (23 kg) compared with the previous model.

5.7 Exterior mirrors


The exterior mirrors were also adopted from the Boxster models. The new design of
the exterior mirrors improves the air flow characteristics, leading to reduced mirror
soiling and less wind noise. The exterior mirrors are now mounted directly on the
doors and are optionally available with electrical folding function and door courtesy
lighting.

The newly designed exterior provides the new Cayman with a very unique
appearance, without moving too far away from the Porsche model family. The side
trim panels are an innovation when it comes to ease of repair from a service point
of view. This chapter contains detailed descriptions of the new features and repair
concepts for the exterior of the new Cayman models.

6.1 General
The modifications were intentionally chosen so that the vehicle is clearly
recognizable as belonging to the Cayman model line, but also so that the new
Cayman appears much more dynamic and athletic than its predecessor. Based on
the new Boxster models, the following main modifications have been made to the
new Cayman in contrast to its predecessor:

cardiagn.com
• Newly designed front and rear sections
• Modified door design with air guides to the rear openings
• Larger air openings in the rear side sections
• Stretched vehicle side contour
• Newly designed tail lights

6.2 Front, side and rear view

Body equipment, exterior


6 Front view

The Cayman remains compact, a fact that is especially underlined by the wheel/tire
combinations flush with the body. The vehicle width at the front is the same as the
predecessor model, while the height has increased by 4 mm. During design of the
new front section, emphasis was placed on character, dynamics and classic
Porsche design elements. Both the halogen headlights fitted as standard on the new
Cayman and the new Bi-Xenon headlights fitted as standard on the Cayman S are
completely new developments. The lateral and central air intakes are larger and
more imposing than on the Boxster models. The radiators, air conditioning
condensers and brakes are ventilated and cooled by the air intakes. In contrast
to the Boxster, the daytime running lights in the Cayman have a round design.

cardiagn.com
6_02_13

Side view

The wheelbase, which has been lengthened by 60 mm, and the 4 mm increase in
vehicle height immediately catch the eye. In fact, the actual increase in length is
actually only 37 mm and the new Cayman therefore still retains its typical compact
external dimensions. The front overhang was reduced by 25 mm. More or less the
same passenger compartment height has been retained. The curvature of the
windshield is more pronounced in the bottom area and the windshield is therefore
raked forward by approx. 100 mm. In combination with the roof contour extended
6_03_13
towards the rear, this provides the vehicle with a very sporty and elegant appearance.

Rear view

The rear design of the new Cayman models is completely new. Powerful curves
alternate with precisely defined lines and edges, which differentiate the Cayman
clearly from the Boxster models. The new rear spoiler is integrated in the design
and is positioned between the tail lights. The visual design of the tailpipe covers
differs between the Cayman and the Cayman S. These have a one-piece design on
the Cayman, whereas the Cayman S features a dual-branch cover.

6.3 Side air intakes


The newly designed air intakes in the rear side section are a distinctive styling
element on the new Cayman as well as on the Boxster models. The contours of the
air intakes extend into the door area. This provides the Cayman with a striking side
taper and underlines its powerful appearance. In addition to their contribution to the
visual design, the new side air intakes naturally also have to perform functional
Body equipment, exterior

tasks.

On the one hand, they are responsible for routing the combustion air to the engine
through air ducts (A) integrated specifically for this purpose. The air is supplied to
the engine after passing through the air cleaners installed on the left and right. As
on the Boxster models, the air cleaners can be accessed through the rear luggage
compartment. On the other hand, they are also responsible for thermal manage-

ment in the engine compartment. They guarantee optimum air flow through the
engine compartment under all load conditions and reliably prevent engine
overheating.

The side skirts are made of plastic. For the Service organization, this means that
repairs to damaged areas on the side of the vehicle can be carried out easily. The
trim panel is clipped and screwed into the bodyshell so that it can be fitted and
removed easily.

6.4 Spoiler

Body equipment, exterior


6 In order to reduce lift at the rear axle, the new Cayman also features the extending
rear spoiler familiar from the Boxster models. The function is realized by a fixed
separation edge and an extending wing. The rear spoiler has been made consider-
ably larger compared with the previous model and now forms an important styling
element of the rear end in combination with the newly designed tail lights.

Special features of the rear spoiler:


• Continued further development of the wing spoiler concept in order to
optimize the drag coefficient
• Increase of 40% in aerodynamically effective area with combined translatory &
rotatory extending movement
• Additional aerodynamic effective area at tail lights and rear apron

Since the entire spoiler mechanism is fitted behind the rear apron and the trim panel
must be detached to facilitate removal, an emergency unlocking system for the
spoiler is essential.

Emergency unlocking – spoiler


Since the threaded joints between the upper and lower parts of the spoiler are only
accessible from behind and therefore only when the spoiler is extended, the spoiler
must be extended manually in the event of a technical fault. For this purpose, the
vehicle must be raised at the rear end and the tailpipe cover must be swivelled
down.

The interior of the new Cayman is based on the interior of the new Boxster models.
When designing the interior, highest priority was given to the choice of materials
and the functional design of the operator control units. Particular attention was also
paid here to ease of repair and maintenance.

The headlights contain the direction indicator, dipped beam and high beam
functions. Bi-Xenon headlights with automatic headlight control (AFS) and halogen
auxiliary high beam are optionally available. LED position lights and daytime running
lights are installed below the headlights in the air intakes. When the automatic
headlights function (automatic driving light assistant) is activated, it switches

between daytime running lights and dipped beam, depending on the ambient
brightness. Only LEDs with the tail light, brake light and direction indicator functions
(direction indicators, hazard warning lights) are used in the rear light modules.
Reflectors have been integrated into the tail light unit.

Porsche Dynamic Light System Plus (PDLS Plus)


The already available “Porsche Dynamic Light System” (PDLS) has been enhanced

and now features a High Beam Assistant and an Intersection Assistant function.
With the High Beam Assistant function, a camera installed in the interior mirror
detects the light sources of vehicles in front and oncoming vehicles and switches
automatically between dipped beam and high beam. The system is activated at a
speed of 40 mph (65 km/h) or higher in order to avoid switching on high beam
headlights in congested areas.

Intersection light

Electrics and electronics


9 The intersection light function detects intersections and junctions using the
navigation data. The system then switches on the left and right static cornering
light simultaneously for optimum illumination at an intersection.

The intersection light function provides the vehicle with significantly better
illumination at an intersection.

9.4 Vehicle access


The remote control (UHF 315/434 MHz) is used for opening and locking the vehicle
doors and for opening the front and rear lid. The underside of the remote control
features a mechanical vehicle key, which can always be used to access the vehicle
via the lock in the driver’s door.

The keyless vehicle access system (Keyless Entry Start System KESSY) optionally
includes additional 125 kHz internal and external antennas as well as two luggage
compartment and proximity sensors. Other functions, e.g. anti-theft warning
system, engine immobilizer, comfort and memory functions, can also be linked
to the remote control, depending on the vehicle equipment and country variant.

9.5 Adaptive cruise control (ACC)

Electrics and electronics


9 Adaptive cruise control maintains a distance to the vehicle is front that is speed-
sensitive and can be preselected (in four steps). It automatically adapts the driving
speed, bringing the vehicle to a halt if necessary, and moves off again automatically
within 3 seconds (Stop & Go) following confirmation by the driver. The programmable
speed range extends from 20 – 130 mph (30 – 210 km/h). When the road ahead is
clear, adaptive cruise control (ACC) behaves like the conventional cruise control
system and maintains the selected target speed.

The difference with ACC is that it can maintain a constant speed even on gradients
by activating the brake system or executing downshifts (on vehicles with Porsche
C
D Doppelkupplung (PDK)). Adaptive cruise control relieves the driver of the task of
