2009-Porsche-Cayman-S

The Cayman now has an engine displacing 2.9-litres, which develops 265 bhp (195 kW), an increase by 20 horsepower over the prior 2.7-litre model.

The 3.4-litre power unit in the Cayman S now features Direct Fuel Injection, and delivers 320 bhp (235 kW), up by 25 bhp.

These developments see the engines fitted to the Cayman and Cayman S coupes offering more horsepower than those in the Boxster roadster. This move emphasises the sports driving orientation of the Cayman and further differentiates the coupe.

An outstanding power-to-weight ratio of 4.2kg/bhp on the Cayman S in particular ensures optimum driving dynamics. For example, the Cayman S with PDK and Launch Control (featured in the optional Sports Chrono Package Plus) accelerates from 0-62mph (0-100 km/h) in 4.9 seconds, setting the benchmark in the range.

When combined with the PDK transmission, the new 2.9-litre engine of the Cayman clearly breaks through the 30.0mpg fuel consumption boundary. Indeed, the figure of 31.0mpg (9.1 litres/100km) is approximately 10 per cent better than the previous model with the Tiptronic S automatic transmission. Increasing fuel economy by an even more significant 15 per cent to 30.1mpg (9.4 litres/100km), the 3.4-litre Cayman S with PDK offers an even greater saving over its predecessor with Tiptronic S.

In parallel with the improvement in fuel economy, so emissions of the engines have decreased also. Depending on model, emissions have been reduced by up to 16 per cent. The Cayman with the standard six-speed manual gearbox emits 221g/km CO2, and 214g/km CO2 when fitted with PDK. The Cayman S manual emits 223g/km CO2, and 221g/km CO2 with PDK.

Significantly, these developments move every Cayman model – whether manual or PDK – into Band F for Vehicle Excise Duty and company car taxation purposes.

Direct Fuel Injection standard on 3.4-litre S engine

The driver benefits from a further advantage of direct injection every time they touch the throttle pedal: with fuel being injected fractions of a second prior to combustion, the engine responds more directly and spontaneously to even the slightest movement of the driver’s right foot. This is not only the case when accelerating, but also when lifting off the throttle, for engine speed drops more quickly and smoothly since there is no residual fuel left in the intake manifold which might otherwise prolong the combustion process.

Depending on engine load and speed, fuel is injected into the combustion chamber at a pressure of 120 bar. The big advantage is that unlike conventional intake manifold injection, direct fuel injection serves to form the fuel/air mixture directly in the combustion chamber. This better mixes the air and fuel in the cylinder, establishing an important prerequisite for clean and complete combustion. This ensures the ‘homogeneous’ operation of the power unit with a consistent balance of the fuel/air mixture in the combustion chamber at all times and under all running conditions. Such smooth operation guarantees optimum combustion and maintains low emissions, across a range of fuel qualities.

PDK: quickly shifting gears, reducing fuel consumption

The Cayman is available with the Porsche-Doppelkupplungsgetriebe (PDK) carried over directly from motor sport, and replacing the former Tiptronic S torque converter automatic transmission. When equipped with PDK, the Cayman accelerates from 0-62 mph (100km/h) 0.1 seconds faster than with the manual six-speed gearbox.

Acceleration is particularly fast and dynamic with the optional Sports Chrono Package Plus featuring Launch Control; this offers maximum acceleration from a standing start and also a Race Track Gearshift Strategy for the fastest conceivable gear change as an exclusive highlight on the PDK models.

Benefiting from Launch Control, the respective models accelerate from a standstill to 62 mph (100 km/h) yet another 2/10ths of a second faster.

A coupé of distinction

While instantly recognisable as a Porsche sports car, the Cayman is
alone in its design. Originally launched in 2005, the adapted contour
of the Cayman has remained beginning and contemporary. Its
characteristic coupé curve are accumulated with a continued wheelbase
and a rear aspect that slopes acclaim downwards. From the rear, the
Cayman is authentic by a large, aperture rear lid, effectively
across-the-board caster arches and an automatically extending spoiler.

The rear lid opens upwards to accommodate admission to the 260
litre baggage compartment. This, in affiliation with the 150 litre
accommodation baggage alcove in the nose, added abundant added
accumulator compartments, ensures that this two-seater sports car
combines absolute functionality with affected artful form.

As is Porsche tradition, the administration of the next bearing
two-seater Coupe has acquired subtly. However, it is acutely apparent
from alfresco through its newly-designed adenoids and tail. The new
halogen headlights with their chip administration indicators are
evocative of the lights on the Carrera GT, and the new LED rear lights
cone-shaped to the alfresco are chip alluringly in the remodelled
bodywork.

The rod-shaped ancillary lights in LED ablaze aqueduct
technology add acumen to the car’s looks, which are added added through
their accumbent adjustment in the alien air intakes. Yet a added
highlight is provided by the annular fog lamps featured as standard.

For the aboriginal time the Cayman is accessible with a Lights
Package featuring bi-xenon headlights, activating cornering lights and
LED day-time active lights. Replacing the fog lamps, these ablaze units
are fabricated up of four LEDs abiding in annular ablaze units like the
eyes on dice.

Porsche Doppelkupplungsgetriebe (PDK) – in detail

The next bearing Cayman and Cayman S are accessible for the aboriginal
time with the new Porsche Doppelkupplungsgetriebe (PDK), in fact
Porsche double-clutch gearbox. Offering no beneath than seven advanced
gears, the new gearbox combines the active abundance of a torque
converter-equipped automated chiral with the activating chiral
gearshift functionality of a consecutive antagonism gearbox. PDK aswell
boasts an absolutely automated gearshift function, and replaces the
Porsche Tiptronic S automated chiral ahead offered. Through its
optimised and adaptive gearshift programmes, PDK added improves the
dispatch of the Cayman models and reduces ammunition burning to an even
lower level.

In principle, the PDK consists of a accepted chiral gearbox and
a hydraulic ascendancy adjustment disconnected into two abstracted
chiral units. Two wet claws in adorable arrangement, controlled
hydraulically, and application oil for both cooling and lubrication,
anatomy the affection of the transmission. One clamp is for the
aboriginal chiral assemblage with the asperous accessory ratios
(1,3,5,7) and reverse, and the added clamp is for the added chiral
assemblage with the even apparatus (2,4,6). Via a amount of burden
valves, the hydraulic ascendancy assemblage masterminds both the wet
claws and the about-face cylinders activating the chiral arrangement
required.

The gearshift perceived by the disciplinarian comes not from
the apparatus in fact changing, but from the change of absolute clamp
engagement. In this case, the clamp on one chiral opens or disengages
while the clamp on the added chiral closes or engages in a accompanying
process. The big advantage is an even faster gearshift than with a
accepted chiral gearbox or torque advocate automated transmission. The
apparatus are already ‘in mesh’ if alive and the ability of the engine
charge not be disconnected in the process.

PDK aswell reduces to a minimum chiral ability accident address
of the top accepted of automated ability in the double-clutch, and this
manifests itself in ammunition abridgement improvements of about 13 per
cent compared with a accepted Tiptronic S transmission. PDK aswell
offers an advantage in agreement of weight – admitting two added gears,
it weighs 10kg beneath than Tiptronic S.

To use the assorted functions of the double-clutch
transmission, the disciplinarian can either about-face apparatus by
agency of sliding buttons on the spokes of the new council wheel, or
via the new accessory selector lever. The disciplinarian can columnist
assiduously to about-face the apparatus up, and columnist them from
abaft to about-face downwards. Alternatively, blame the accessory
selector batten assiduously accouterment up a gear, and affairs it
aback accouterment down. The advantage of PDK costs £1,961.

This PDK gearshift assumption was aboriginal developed by
Porsche for motor action 25 years ago. Porsche works drivers benefiting
from this technology were able to advance faster than their competitors
and accumulate both easily on the council caster while alteration
gears, appropriately alienated even the aboriginal aberration while
shifting.

The seven-speed PDK accouterment apparatus up to 60 per cent
faster than a accepted automated transmission, and naturally, gives the
new Cayman models even bigger performance. And those in seek of optimum
active dynamics accept the advantage to amalgamate PDK with Action
Chrono Package Plus, now featuring Launch Control.

New audio and advice systems

The next bearing Cayman appearance as accepted the new CDR-30 CD radio.
The new Porsche Advice Management (PCM) 3.0 complete with harder disc
aeronautics is accessible as an advantage and if defined serves as the
axial ascendancy assemblage for all audio, advice and aeronautics
features.

PCM 3.0 is added versatile, able and easier to use than before,
continuing out in accurate through its touch-screen which enables the
disciplinarian to baddest specific functions artlessly by acute the
adapted key on the beyond 6.5-inch monitor. PCM 3.0 is accessible with
awful acceptable articulation ascendancy and, in affiliation with the
optional, accepted audio interface, can now be acclimated aswell to
ascendancy alien audio sources such as an iPod®, USB stick, or
Bluetooth.

Seat blast accumulated with bench heating is aswell accessible as an option.
