Porsche Cayman R 2011


The Porsche letters in order holds the letter R for exceptionally extraordinary games vehicles: R for responsive and refined - however most particularly for suggestive. The new Porsche Cayman R consolidates this load of properties without compromise. The mid-motor Coupé is lighter and more impressive than the Cayman S and in this manner speedier and more productive, and is planned only for driving elements.
With its uncommonly adjusted games frame, it gives a much more exact driving experience than the Cayman S.The fundamental point during the plan of the Porsche Cayman R was to further develop the two-seater considerably further in its presentation, driving elements and deftness through steady weight decrease. Generally, the vehicle weight of the Cayman R was decreased by 55 kilograms to a DIN void load of 1295 kilograms contrasted and the Cayman S. This implies that the Porsche engineers had the option to lessen the ability to-weight proportion of the Coupé with standard manual transmission to 3.9 kilograms per torque, and the PDK rendition has 4.0 kilograms per pull. The biggest investment funds were accomplished using lightweight parts and managing without accommodation fittings. For instance, the series variant isn't fitted with a cooling framework or radio, which brings about 15 kilograms less vehicle weight. On the bodywork side, a further 15 kilograms was saved using aluminum entryways as utilized in the 911 Turbo. Light games can seats don't simply work on the driver's side help in twists, yet they additionally add to a further weight decrease with a saving of around 12 kilograms contrasted and the customary seats utilized in the Cayman S. The decreased entryway trim without capacity compartment and with entryway opening tie, forgoing the instrument group cover and the cupholder notwithstanding a wide scope of minor marks adjust the lightweight bundle. With respect to the 911 GT3/GT3 RS and Boxster Spyder, a discretionary lithium-particle lightweight development battery is likewise accessible. Also, the top model in the mid-motor Coupé is outfitted with the lightest 19 inch wheels the whole Porsche program can offer. The 10 spokes are so finely planned - yet amazingly hearty - that the total edge set just gauges 40 kilograms.The Porsche Cayman R's motivation and perfectionist character can be seen right away. The drawn out outline of the bodywork, which has been brought by 20 millimeters contrasted down with the Cayman S, joined with the particular fixed back spoiler, the top notch silver-painted haggles wearing accentuations in both the inside and outside guarantees a singular appearance.

The outside mirrors along with the "PORSCHE" lettering as an afterthought, the parallel air admissions and the back spoiler top segment - in differentiating dark or silver, contingent upon outer shading - , notwithstanding the dark outlined headlights follow the traditional Porsche hustling vehicles.Definitively this "PORSCHE" lettering was the brand name of the main Porsche with the "R" assignment, the 911 R of 1967. It was made for hustling sport use in a little series of 19 vehicles for a little circle of top private drivers and, obviously, for the actual organization. The "R" was a model dependent on the series Coupé with a 210 strength Carrera 6 motor and, gratitude to its numerous plastic parts and very scanty fittings, weighed just 830 kilograms. The 911 R exhibited its security and speed on the 84-hour "Long distance race de la Route" on the Nürburgring in 1967, where Porsche utilized the race as a welcome perseverance test for another series part: Vic Elford, Hans Herrmann and Jochen Neerpasch won in a 911 R fitted with the new Sportomatic transmission. The victories cumulated. Entered by the production line, the 911 R was additionally a champ during the "Visit de France" driven by Gérard Larrousse in 1969. The Porsche Cayman R motor doesn't simply put out 10 pull more than the 3.4 liter Cayman S motor of a similar size, it is additionally extensively more unconstrained. The fundamental justification behind the expanded force is the changed fumes framework with its new head pipe and an adjusted motor control. Similarly with respect to motors made for engine hustling, the Porsche Cayman R six-chamber has been worked to the high-firing up idea and produces its most extreme force of 330 hp at 7400 rpm, 100 rpm before its rotational-speed limit. This empowers the driver to utilize the stuff proportions of the manual transmission or PDK far and away superior and to diminish the lap times. To coordinate with this, the gas pedal control trademark bend has been planned with the accentuation on sport, so the Porsche Cayman R responds amazingly suddenly and capably to the driver's orders in transaction with the uniquely coordinated with Porsche twofold grip transmission (PDK). The level motor, which was assembled following the exemplary Porsche standards, gives ideal conditions to use in the reliably driving elements situated Porsche Cayman R. Low weight, level development with low focal point of gravity, decreased inside contact and low moving mass guarantee elite at synchronous low fuel utilization. This implies that the Cayman R just devours 9.7 liters per 100 kilometers (3.43 gallons pixie. per 100 miles) - 0.1 liters not exactly the Cayman S. The crankcase is partitioned in two and fabricated utilizing the shut deck development framework. The motor suspension with extra cross over stops and exceptional suspension ID guarantee donning solace at high driving elements since the unit is fixed all the more solidly and accordingly permits less relative development to the body. Porsche likewise utilizes direct fuel infusion in the new Cayman R's 3.4-liter motor. The carburetion depends on homogenous direct infusion activity. The fuel, which is infused straightforwardly into the burning chamber, blends in with the new acceptance air amazingly equally to empower ideal ignition. The injector is situated between the two admission valves and spots its infusion flies straightforwardly into the two wind streams. This implies that air and fuel are blended much better in the chamber - a significant essential for perfect and complete burning. Direct infusion doesn't simply positively affect the proficiency, yet additionally on the qualities of the Cayman motor. The driver can feel this straightforwardly: since the fuel is infused parts of a second prior to the ignition, the motor responds rapidly to any development of the gas pedal. The motor gives the force needed by the driver completely as ahead of schedule as the following burning cycle following positional changes of the gas pedal pedal.The Porsche Cayman R imparts its eagerness to perform to the driver directly from the beginning. This implies that the motor responds with the complement on coordinated with an unmistakable speed invade when the warm motor is turned over. The motor sound has been improved once more with inside motor measures and took on to the by and large lively impression. For instance, the altered motor control makes the notable engine dashing "mumbling" sound during following choke state. The games motor breathing qualities are controlled by means of the great speed-tried VarioCam Plus camshaft change created by Porsche, with its admission side planning changes and valve lift switchover. The valve lift change is done by powerfully controlled pail tappets on the motor admission side which are worked by two in an unexpected way estimated cams on the admission camshaft. On account of VarioCam Plus, ideal force and force can be accomplished. Likewise, this framework further develops fuel utilization, emanation conduct and motor refinement. In mix with the immediate fuel infusion, this outcomes in an increment in force and force simultaneously as a decrease in fuel consumption.The request controlled oil siphon likewise has its impact in the excellent effectiveness of Porsche motors. The oil flow has been constructed dependent on the standard of incorporated dry-sump oil and comprises of an oil siphon with four pull and one controlled tension stages. The motor administration adjusts the siphon ability to current necessities whenever. A cogwheel which can be using pressurized water moved along its pivot, which implies that the getting tooth width and thusly the mathematical removal volume of the cogwheel set is changed, is utilized for this reason. This implies that the oil siphon utilizes no more energy than is required and all the while guarantees oil which matches necessities. A reverberation admission framework fitted with a reverberation and conveyance pipe between the righthand and left-hand consumption complex is liable for natural air guideline for the 3.4-liter motor. The controlled tuning fold empowers transformation of the air vibrations in the admission framework to the comparing motor speed, high force even at low upsets, an all the more even force bend and high greatest force. The twin-stream appropriation pipe with control valve likewise works on the force at low motor transformations.The motor satisfies as far as possible qualities as per Euro 5 and the ULEV (Ultra Low Emission Vehicle) Standard for the USA. To accomplish this, the 3.4-liter motor works with the alleged high-pressure defined charge infusion on chilly beginning with a resulting exhaust system warming stage. Here, the double infusion expands the fumes gas temperature and along these lines warms the exhaust system up as fast as could really be expected. The fuel-air blend is touched off at an exceptionally late stage which further builds the fumes gas temperature and decreases outflows during the beginning up stage. At last, the fumes framework with its two motor narrows pre-exhaust systems coordinated in the elbows and its two principle exhaust systems guarantees as ahead of schedule and complete as conceivable cleaning of the fumes gas. The Porsche Cayman R fumes framework depends on the one utilized in the Cayman S, however it has a head pipe with expanded breadth which brings about additional de-choking on the fumes gas side. In blend with the new motor application a force increment of 10 hp at higher upsets is accomplished thusly. The twin-stream twofold tailpipe of the Cayman R is hued brandishing dark. The games exhaust framework, which is accessible on demand, gives a great acoustic encounter. It is additionally fitted with a twin-stream twofold tailpipe, yet for this situation the surface is treated steel cleaned with a nano-covering. A six-gear manual transmission fitted as standard in the Porsche Cayman R communicates the motor capacity to the back hub. The stuff proportions are intended to help and match the motor's energetic attributes impeccably, and the stuff shifts during moving up guarantee winning advances speed increase in mix with the high-firing up motor. A short shifter is additionally accessible for especially sportingly-disapproved of drivers. Much more energetic and surprisingly more frugal: the Porsche twofold grasp transmission (PDK).The discretionary seven-gear Porsche twofold grip transmission (PDK) is additionally accessible for the Porsche Cayman R for additional enhancements to elements and financial proficiency. On a fundamental level, the PDK is a traditional manual transmission partitioned into two split transmissions with a water powered control unit. The center of this transmission is shaped by two concentrically organized multi-plate grasps settled inside one another in an oil shower, which are using pressurized water worked. One grasp is answerable for the principal parted transmission with odd-numbered pinion wheels and converse stuff, the other grip is liable for the second parted transmission with its evennumbered gears. The water powered control unit impels both the grip and the change chambers for changing into the necessary gear proportions through various strain valves. The stuff shifts occur amazingly rapidly, without jolting and without interference to the force stream in light of the fact that the grip for one split transmission discharges at the very same time as the other grasp locks in. The significant benefit is that stuff moving is up to 60% faster than with manual or force converter programmed transmissions on the grounds that the cog wheels have effectively been locked in during moving. The stuff shift system given by the PDK has been completely reexamined for the extremist, puristic Porsche Cayman R. This prompts considerably greater deftness for the mid-motor games vehicle in every working region. The versatile changing in the more lively outfitting coordination presently happens after a couple of gas pedal developments, the transmission gadgets responds all the more rapidly and all the more straightforwardly to the driver's prerequisite for more liveliness. This implies that the vehicle holds its force in all pinion wheels, speed increase out of curves is conceivable with a lot higher force move to the wheels, and the driver is associated straightforwardly to the motor and transmission through the gas pedal. The spryness has additionally been improved during slowing down moves not long before close curves. The slowing down shift-downs are more unconstrained and done at a higher motor rates, which implies prior. Generally speaking, the motor speed level among unbiased and the change accelerate to the following most noteworthy gear has been adjusted to the high-firing up motor. In the event that the selector switch is set to D, gear-changing happens totally consequently. As opposed to the next Cayman Coupés, the moving focuses have been changed a lot later in each program so the driver can utilize the motor speed range. In mix with the PDK the Porsche Cayman R has been fitted with a three-talked sports controlling wheel with gear-shift paddles, of which the right-hand paddle is answerable for moving up and the left-hand for moving down. The transmission reaction times in programmed and manual modes have been abbreviated considerably more in examination with the other Cayman Coupés so the driver can assume direct responsibility for power which is communicated from the wheels to the street. Grasp activity happens without driver activity for each situation. Pinion wheels one to six are dispersed sportingly - the Porsche Cayman R accomplishes maximum velocity in 6th stuff. The seventh stuff is planned with a higher stuff proportion for less fuel utilization. Game Chrono bundle with Launch Control and dashing stuff change technique .Things settle the score better. To utilize the new Cayman R's capability to its fullest, Porsche currently offers the Sport Chrono or Sport Chrono Plus bundles for the mid-motor games vehicle. The game button in the mid control area is utilized to actuate the game mode for both the motor and Porsche Stability Management (PSM). In the event that the vehicle is outfitted with PDK the Sport Plus button, which programs the twofold grip transmission for particularly quick stuff moving, is fitted. This implies that an uncompromisingly lively shift program is actuated for the absolute best in driving presentation on the circuit. On top of this, the Sport Plus program permits initiation of the purported Launch Control for the most ideal beginning speed increase. To accomplish this hustling start, the driver needs to activate the brake pedal with his left foot and utilize his right foot to press the gas pedal directly down (kick-down). This controls the motor to a speed of 6500 rpm. When the driver takes his foot off the brake pedal, the vehicle begins with the greatest conceivable speed increase. The Porsche Cayman R oversees 0 to 100 km/h (62 mph) in just 4.7 seconds, as such 2/10 of a second faster than previously. The Sport Chrono Plus bundle is utilized in models with the discretionary PCM. It offers an extra exhibition show in the instrument group and individual recollections for light, wiper and entryway lock settings. The phenomenal elements of the new Porsche Cayman R are connected straightforwardly to the uncommonly created and adjusted games frame. The remotely noticeable indications of this are that the new top model in the two-seater Coupé range is around 20 mm lower than the Cayman S. This bringing down is combined with more limited, more inflexible springs and tweaked against roll bars on the front and back axles. On top of this, the tallness of the focal point of gravity has been brought down by a further two millimeters through weight-saving measures so this is presently 22 millimeters lower generally. Stiffer tuning has additionally been completed on the dampers. The Porsche Cayman R's dads have passed on a following width which is four millimeters more extensive at the front and two millimeters more extensive at the back because of bigger wheels with changed offset. The very light wheels lessen the unsprung weight and also work on the driving accuracy. This case plan - regarding the to a great extent leveled out hub load dispersion and the situating of travelers and motor between the axles - permits an amazingly unique method of driving with expanded driving security and high sidelong speed increase in the Porsche Cayman R. The R model cows with significantly more readiness and accuracy than the other mid-motor Coupés. Influence and pitch have been totally dispensed with. The similarly long wheelbase guarantees extra adjustment, particularly during straight-ahead driving. The front wheel suspension involves a spring swagger pivot with following arms and wishbones. This plan guarantees exceptionally exact wheel direction joined with a serious level of ride solace. Extra bounce back support springs in the damper swagger lessen the influence point, as such the Coupé stays more steady even at high parallel speed increase. The back spring swaggers are upheld in extraordinary spring seats which moreover clammy transmission of effect, commotion and vibrations to the body and subsequently increment the ride solace considerably more. A bigger negative camber has likewise been set on the two axles to expand the directional security potential. The driving elements benefits of these case changes are underlined ideally in the Porsche Cayman R. The very high solidness and torsional unbending nature of the Cayman body offers the ideal reason for most extreme guiding accuracy. Considering the puristic and donning plan of the Cayman R, Porsche is getting rid of the discretionary extra of the Porsche Active Suspension Management (PASM) electronically-controlled damper framework. A back pivot differential lock is underestimated in a games vehicle with incredibly energetic tuning. It has been intended for 22% securing esteem foothold and 27 percent in impetus. This implies that both foothold and strength have been extensively improved, which thusly brings about recognizable execution gains on winding courses, particularly on circuits. A further advantage is the more steady burden change conduct. On top of this, the mechanical limitedslip differential alleviates the electronic brake activation (ABD) of the Porsche Stability Management (PSM) through its working rule, since wheelspin is postponed on streets with less grip on one side due to the locking effect.As in the case of Porsche's other mid-engine sports cars, the hydraulically-assisted rackand- pinion steering transmits the driver's steering commands with variable steering ratios in the Cayman R as well. Firstly this makes excellent agility on winding roads possible, and secondly outstanding driving stability at very high speeds is simultaneously available. The steering ratio is larger in the central position, in other words during minor steering wheel turns. This means that the Coupé behaves extremely stably, especially at high speeds. If the steering wheel is turned by more than 30°, the steering ratio becomes increasingly more direct. This results in considerably more agility on winding roads and more manageability, for example when turning off, in tight bends or during parking. The steering wheel turns around two and a half rotations from stop to stop.Perforated and internally ventilated brake discs ensure excellent deceleration as standard. At the front, four-piston aluminium monoblock fixed callipers with a diameter of 318 mm (12.52") and a thickness of 28 mm (1.1") are used. On the rear axle, 24 mm (0.94") thick brake discs with a diameter of 299 mm (11.77") ensure optimum deceleration, and these are also gripped by four-piston aluminium monoblock fixed callipers.The Porsche Ceramic Composite Brake (PCCB), which is available as an option, provides its very own braking dimension. The package consists of ceramic discs of 350 mm (13.78") diameter on all four wheels, and special brake pads provide extremely high and especially constant deceleration in connection with the yellow-painted six-piston aluminium fixed callipers on the front axle and four-piston aluminium fixed callipers on the rear axle. This guarantees extremely short braking distances even under extremely high requirements.The Porsche Stability Management (PSM) ensures high active safety in its new development stage as standard. PSM includes ABS (anti-lock brake system), ASR (traction control system), MSR (engine braking control system), ABD (automatic braking differential) and the "Prefilling of brake system" and "Braking assistant" functions. Pre-filling of the brake system increases the brake readiness and assists in reducing the stopping distance in emergency situations. As soon as the accelerator pedal is released rapidly, which is characteristic for forthcoming emergency braking, a specific amount of pressure is built up on the wheel brakes by the PSM hydraulic unit even before the brake pedal is actuated. This means that the brake pads are applied lightly to the brake discs. The response characteristics of the brake system are therefore improved considerably and the stopping distance is reduced.The Brake Assistant is also responsible for reducing the stopping distance. As soon as the system detects emergency braking - when a specified actuation speed and a defined pedal force at the brake pedal is exceeded - the PSM hydraulic unit actively provides the brake pressure required for maximum deceleration. However, in order to prevent unwanted actuation of the brake assistant during very sporty driving, for example during circuit racing, the system is deactivated when the PSM has been switched off (PSM OFF) or if the optional Sport Chrono package sport button has been pressed.As a basic rule, the PSM acts to ensure increased stability in critical driving situations close to the absolute limits through selective brake actuation. This means that the system can offer extremely high active driving safety along with the agility expected of a Porsche car, and therefore increased driving enjoyment. In order to make agile handling possible in tight bends, the PSM comes into operation later at lower driving speeds of up to around 70 km/h (43.5 mph). The driver can also switch off the PSM so that it only becomes active again during braking. Reactivation of the system only takes place if the brake pedal is depressed strongly and once the ABS regulation limit has been exceeded on at least one front wheel. The sporting driver can therefore enjoy considerable leeway since no PSM intervention takes place during light braking, which allows the vehicle to be braked neutrally into bends.The best chassis, the most powerful braking system and the most dynamic drive can only be transformed into high driving performance if the common link - the body - is adopted correspondingly. The Porsche Cayman R has a huge initial advantage in this case: its structure is based on the Boxster, which has been constructed as an open sports car and therefore provides extremely high stability even without a roof. The integration of a fixed coupé roof resulted in an extremely rigid and torsionally stiff body which is now setting standards in the midengine sports coupé segment.This extremely high stiffness has, on the one hand, immediate effects on the precision of the chassis: even major stimulation has absolutely no influence on the body structure geometry, which means that the chassis geometry remains unchanged - the sports Coupé appears to run literally on rails. On the other hand, stiff bodywork also means high passive safety. The Porsche Cayman R fulfils all current valid regulations in the relevant markets with respect to passive vehicle safety. It falls well below the limit values required by the legislators for frontal, oblique, side and rear impact in addition to rollover.The front luggage compartment lid on the sport Coupé is a shell structure in aluminium. The Porsche Cayman R's doors result in a further 15 kg of saved weight because, in comparison to the other Cayman models, they are manufactured in aluminium. The wide-opening tailgate with its large, heatable rear window in lightweight steel construction fits snugly in the flowing lines of the vehicle rear. A wiper for the rear window is available as an option.It's only natural that the Porsche Cayman R provides the same passive safety system as all Porsche sports cars. A head airbag combined with a thorax side airbag on the driver and passenger sides provide excellent protection against side impact over the entire longitudinal adjust ment range of the seats. Porsche calls this combination POSIP, which is short for Porsche Side Impact Protection. The full-size airbags provide just as much protection against injury caused by frontal impact with their 62 litres on the driver side and 122 litres on the passen ger side.Tracking stability and road grip play an important role in safety and lateral stability in sports cars used for racing, especially at high speeds. For this reason, the Porsche engineers have reworked the Cayman R's aerodynamics in detail and have achieved considerably reduced lift values on both axles. The lift has been reduced by around 15 percent at the front axle, and by 40 percent at the rear axle. This is attributable to the more pronounced front spoiler lip and the fixed spoiler at the rear. It replaces the automatically extending split wing which is fitted as standard to the other Cayman models, and is based on a different aerodynamic principle. Optimised deflection blades for cooling air to the wheel housing panels also optimise brake cooling. The Porsche Cayman R has a Cd value of 0.30 both with manual six-gear transmission and with PDK.The interior of the new Porsche Cayman R presents itself in sporting functionality, and has been designed with the focus on purism, ergonomics and authenticity. The interior colour is principally black, and is supplemented with components in the exterior colour or colour accents of red or silver.The fittings are concentrated on the essentials for reasons of weight. There is a storage compartment instead of a radio, the door pockets have been left out completely and the cupholder is only available on request. Instead of the metal levers normally found in Porsche cars, the Cayman R is fitted with a light fabric strap in the inside panelling for opening the door. Even the surround flanking the instrument cluster with its black instrument dials was on the Porsche Cayman R hit list. The centre console and decorative moulding around the switch panel are painted in vehicle colour. The fitting colour is black as standard with accented details in contrasting colours: the gear diagram on the shift lever, the door opening straps and the seatbelts are coloured in a contrasting luminous red or black depending on the external colour, and are also available in silver as an option.The Cayman R is fitted with light sports bucket seats with a seat centre in Alcantara as standard. The seat shell construction is made of glass and carbon fibre-reinforced plastic, and plays an important part in weight reduction to a level of around 12 kilograms compared with the standard seats fitted to the Cayman S. The seat shell surface is finished in an optically attractive visible carbon.You can take it for granted that the Porsche Cayman R offers every customer the opportunity to adapt the two-seater to his individual requirements. This is why almost all the options in the Cayman program are also available for the new R-type, and these range from climate control through a complete leather interior right up to Bi-Xenon headlights with dynamic cornering lights and LED daytime driving lights. The sports seat can be ordered at no extra cost as an alternative to the extra-light standard sports bucket seats. The CDR-30 audio system can also be fitted at no extra cost on request. It is fitted with an easily-readable 5-inch monochrome screen. The integrated CD drive also plays music in MP3 format.The Porsche Communication Management (PCM) including navigation module is also optionally available. It is used as a central controller for all fittings in the audio, communication and navigation sector. Its main feature is the 6.5 inch touch screen. In addition, external audio sources such as an iPod® or USB stick can be controlled via the PCM with the optionally available universal audio interface. Instead of the standard single CD/DVD drive, an integrated six-fold CD/DVD changer which is comfortably within the driver's reach is available as an option in PCM.
