Unyielding. Resolute. Strong-willed. The perfect match. Do you go your own way? Do you stop to question the rules, and prefer to make your own? Would you rather trust your own mind than go with the flow? Then this is the place for you. Right here in the driver's seat. The new Cayman and Cayman S. An uncompromising declaration of individuality. 6 7 Cayman | The concept The primary target group: your central nervous system. The new Cayman and the new Cayman S. Two different characters. One personality. Their drive for power is impressive, their spirited nature fascinating. Two sports coupés that go beyond all conventions. Two cars that draw their drivers under their spell, forever. construction, power output and efficiency. The new Cayman has a 2.9-litre flat-six engine with a power output of 195 kW (265 hp). (PDK, p. 48) is also available as an option. The key elements of PDK are its seven gears, two half gearboxes Even more impressive are the performance values of the new Cayman S, now with direct fuel and two clutches. It features both manual and automatic modes. Gears are changed using the new gear selector for PDK or the switches on the new three-spoke sports steering wheel. The gear change takes place in a matter of milliseconds without any interruption in the flow of power. The advantage over a fully manual transmission is the considerably faster rate of acceleration for the same rate of fuel consumption. The concept behind the Cayman models is the `Le Mans Coupé', a sports coupé designed in 1953 specifically for this legendary race and based on the 550 Spyder. Its mid-engine layout is what made this car special.The car's low centre of gravity gave it tremendous agility and cornering dynamics. From this one basic idea came great success, and with this success our experience grew. The result? Two sophisticated sportscars. The new Cayman and the new Cayman S. injection (DFI, p. 34). The fuel/air mixture is prepared entirely in the combustion chamber after having been metered and injected directly, with millisecond precision. This means even more power and torque. To express this in figures, its 3.4-litre flat-six engine unleashes a mighty 235 kW (320 hp). Depending on the model, it has been possible to reduce fuel consumption by up to 15 % and CO2 emissions by up to 16 %. The advantage over a fully automatic transmission is a perceptible increase in driving dynamics ­ with a similar level of comfort, and a distinct reduction in fuel Their uncompromising performance is generated by two brand new engine developments, which stand out above all for their lightweight In either model, this tremendous power is delivered to the road by a precision six-speed manual gearbox.

Porsche Stability Management (PSM, p. 72), which is available as standard, makes you feel even safer and now comes with two additional functions: precharging Side Impact Protection System (POSIP, p. 74) with head and thorax airbags. For a driving experience that is even more involving, consider the optionally available Sport Chrono Package (p. 62). It offers even sportier tuning of the engine and chassis at the push of a button. of a resolutely dynamic driving experience. Optional seat ventilation keeps you A look inside the passenger compartment leaves you in no doubt that the car was designed for uncompromising sportiness. All the cool when the weather is very warm, while the heated steering wheel is a welcome feature on particularly cold days. The new, In fact, there remains only one thing to consider: which one suits you best? The new headlight design and new LED taillights are a striking feature. Bi-Xenon headlights including LED of the brake system, and brake assist. 10 11 Cayman | The concept Front design (Cayman S) Rear design (Cayman) They say that clothes make the person. But only style makes you unmistakable. Design. The design of the new Cayman models is befitting of their distinctive, sporty character. 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 new Cayman models. The front end has been restyled with enlarged air intakes that hint at the performance within. 18 19 Cayman | The concept Front design (Cayman) Rear design (Cayman S) 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.

Below, you cannot miss the visible hallmark of the characteristic Porsche sound: the new stainless steel tailpipe ­ twin tailpipes on the Cayman S ­ integrated into the new rear end. The unmistakable styling of the Cayman models is complimented by the new 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 new Cayman models. Even more sophisticated, even more dynamic, and when it comes to style, they trust in only one direction: their own. 22 23 Model range The forecast for the following pages: an imminent storm. It's not just about the drive for individuality or supreme performance. Above all, it's the indescribable intensity with which the new Cayman models express these two virtues. Uncompromising. Unyielding. Completely unimpressionable, but extremely impressive. 24 25 Cayman | Model range You should never doubt your own principles. The new Cayman. Top speed is 164 mph (265 km/h) in conjunction with the manual gearbox. Equally impressive, however, is the 10 % reduction axle for an even shorter braking distance and improved safety.

The new, integrated CDR-30 audio system with 5-inch display comes as standard and an integrated six-disc CD/DVD autochanger is available as an option. Precisely this attitude is the driving force behind the new Cayman: the absolute conviction to remain true to oneself. No middle roads. No compromises. No nonsense. layout, which ensures a low centre of gravity and thus a high degree of agility and an extremely sporty drive.

The power of the engine is delivered to the road by a precision six-speed manual gearbox. To cope with the increased engine power output, the new Cayman has enlarged brake discs at the front And the interior? The overall impression is simply one of high quality. For instance, the rims of all optional steering wheels are covered in smooth-finish leather. The front centre console has been The new Cayman has found its way. Its own? Without doubt. One of the features that exemplifies this attitude is the mid-engine The engine delivers a power output of 195 kW (265 hp) at an engine speed of 7,200 rpm.

Top speed isn't reached until 172 mph (277 km/h). Porsche Doppelkupplung (PDK, p. 48) is available as an option. also differs from the new Cayman in its appearance. It has a front spoiler painted in the vehicle's exterior colour, and a new twin tailpipe in stainless steel. The sound? Distinctive. In keeping with the rest of the new Cayman S. To deliver the increased power output to the road, the Cayman S is fitted with 18-inch Cayman S II wheels. Their new design exudes pure dynamism ­ as befits the model's overall look. To accept no compromises, to make conscious decisions, to be governed by nothing other than one's own free will, and to have a clear point of view. A highly promising way to build a sportscar. For us, it's the only way. It is from this philosophy that we developed the new mid-mounted engine with a 3.4-litre capacity and direct fuel injection (DFI, p. 34). The engine delivers a power output of 235 kW (320 hp) at 7,200 rpm, and a maximum torque of 370 Nm is achieved at 4,750 rpm. It has been possible to reduce fuel consumption by up to 15 % and CO2 emissions by up to 16 %, depending on the type of gearbox. The fastest rate of acceleration of 4.9 seconds is achieved in conjunction with the optional Sport Chrono Package. In summary, the new Cayman S But so much power also needs to be tamed. This is the task of the optimised brake system with is more than just a sportscar. It's a Porsche. In addition to having a higher power output, the new Cayman S four-piston aluminium monobloc fixed calipers in a striking red painted finish. 28 29 Drive If you want to take your goals by storm, you had better have the necessary equipment. Two new engines, several goals: increased power, improved driving dynamics, reduced fuel consumption and lower CO2 emissions. The engine is positioned in the middle of the car, 30 centimetres behind the driver. Just a few centimetres above road level. Any contact with the accelerator pedal unleashes power that knows only one direction: forwards. And a sound that is second to none. 30 31 Cayman | Drive Two examples of the uncompromising efforts of our engineers. Going forward. The engines of the new Cayman models. The flat-six engines. Both Cayman models are equipped with brand new engine developments, but have retained the familiar layout: six horizontally opposed cylinders. The 2.9-litre engine of the new Cayman delivers 195 kW (265 hp) at an engine speed of 7,200 rpm. The maximum torque of 300 Nm is achieved between 4,400 and 6,000 rpm. The new engine of the Cayman S has a 3.4-litre capacity and, for the first time, direct fuel injection (DFI, p. 34). Power output is 235 kW (320 hp) at 7,200 rpm. Maximum torque: 370 Nm at 4,750 rpm. Each of the new engines convinces with its outstanding performance figures, extremely smooth running, optimised gas cycles and tremendous cornering agility, with fuel consumption and CO2 emissions reduced by up to 15 % and 16 %, depending on the model. All of this is achieved by DFI (in the Cayman S), a lightweight construction and a host of other engineering advancements, e.g. VarioCam Plus (p. 43). This system increases torque in the lower engine speed range and power output in the upper engine speed range. Injection and ignition are controlled by the engine electronics. The driver regulates engine power ­ and of course sound ­ using the extremely sensitive electronic accelerator pedal. 280 260 240 220 195 kW (265 hp) 180 160 140 120 100 80 60 40 1000 1500 2000 2500 3000 3500 4000 4500 5000 5500 6000 6500 7000 7500 300 Nm 440 420 400 380 340 320 300 280 260 240 220 200 Engine speed (rpm) Cayman: 300 Nm between 4,400 and 6,000 rpm, 195 kW (265 hp) at 7,200 rpm 280 260 235 kW (320 hp) 240 220 370 Nm 440 420 400 380 180 160 140 120 100 80 60 40 1000 1500 2000 2500 3000 3500 4000 4500 5000 5500 6000 6500 7000 7500 340 320 300 280 260 240 220 200 Engine speed (rpm) 3.4-litre flat-six engine of the Cayman S Cayman S: 370 Nm at 4,750 rpm, 235 kW (320 hp) at 7,200 rpm 32 Torque (Nm) Power (kW) 200 360 Torque (Nm) Power (kW) 200 360 33 Cayman | Drive Cayman S Direct fuel injection (DFI). The new engine of the Cayman S has direct fuel injection (DFI). With millisecond precision, fuel is injected at up to 120 bar directly into the combustion chamber by means of electromagnetically actuated injection valves. homogeneous distribution of the air/fuel mixture and, therefore, effective combustion. Multiple DFI improves the internal cooling of the combustion chamber by having the mixture prepared directly in the cylinder. This allows for a higher compression ratio (12.5:1) which helps to deliver more output along with enhanced engine efficiency. It has therefore been possible to reduce fuel consumption by up to 15 % and CO2 emissions by up to 16 %, depending on the type of gearbox. Injection is regulated by the electronic engine management system. The exhaust gas cleaning system ensures that emissions remain well below even the strict limits of the EU5 emission standard, thus helping to protect the environment. The spray and cone angles have been optimised for torque, power output, fuel consumption and emissions by enabling a fuel injections take place, depending on the driving style. 34 35 Cayman | Drive 1.

The advantages are their low weight and reduced fuel consumption. Thanks to ingenious design down to the finest detail, it has been possible to reduce the weight of the new generation of engines even further, e.g. by fully integrating the camshaft bearings into the cylinder heads. Integrated dry-sump lubrication. The purpose of integrated drysump lubrication is to guarantee a reliable oil supply while reducing engine temperatures, even in sportily driven cars. The oil reservoir is located inside the engine. Four oil pumps remove the oil from the cylinder heads directly into the oil sump. A fifth pump in the oil sump directly supplies the lubricating points in the engine. cally controlled oil pump supplies the lubricating points inside the engine as and when required. This means that the oil pump does not work so hard when there is less demand for lubrication. The benefits of this oil supply system include optimum efficiency com- For the engine, these detailed solutions mean a consistent supply of oil regardless of gravitational loads, even in the most demanding track conditions. To reduce power loss and increase efficiency, an electroni- bined with a reduction in both fuel consumption and CO2 emissions. 38 39 Cayman | Drive Input data Engine speed (from crankshaft) Regulation/control of Ignition Engine load Throttle-valve angle Lambda sensor signals Knock sensor signals Electronic engine management Inlet camshaft phase angle Manifold injection (Cayman)/Direct Fuel Injection (Cayman S) Idling via throttle valve and ignition ME 7.8/Cayman ­ SDI 3.1 /Cayman S Heating of lambda sensors Fuel pump (Cayman)/fuel pumps controlled on-demand (Cayman S) Fuel-tank venting Camshaft position Valve lift switchover (VarioCam Plus) Secondary-air injection (Cayman) Engine fan Starter Continuously variable oil pump Fuel pressure (Cayman S) Throttle valve Temperatures ­ Coolant ­ Intake air ­ Air in engine compartment ­ Engine oil ­ Ambient air Cayman Engine cooling system.

Since the six cylinders never all work under immediately. This also prevents increased pollutant emissions and unnecessary fuel consumption. 40 41 Cayman | Drive Two-stage resonance intake manifold. The intake manifold with doubleflow distributor pipe has an adjustable flap that closes and opens at defined engine speeds. As a result of a two-stage resonance effect, the air mass in the intake manifold begins to oscillate, which in turn generates a turbocharging effect and optimises induction. These two effects combine to produce higher torque at low engine speeds, a flatter torque curve and increased power output at high engine speeds, while the acoustic properties of the system are second to none. A sound that is typically Porsche. This two-in-one engine concept seamlessly adapts in response to driver input. The result: instant acceleration and extremely smooth running. To improve throttle response during the warm-up phase, VarioCam Plus selects high valve lifts with retarded valve timing. In the middle and low load ranges, low valve lifts with advanced The variation in intake timing is steplessly controlled by means of an electro-hydraulic rotary vane adjuster at the head of the corresponding camshaft. timing reduce fuel consumption and exhaust emissions. High valve lifts generate high torque and maximum output. VarioCam Plus. VarioCam Plus combines variable valve timing with two-stage lift on the inlet side. This results in smoother running, better fuel economy and lower exhaust emissions. As well as greater top-end power and low-end torque. VarioCam Plus 42 43 Cayman | Drive Cayman tailpipe Cayman S exhaust system Cayman S twin tailpipe Cayman S Ignition system. The ignition system is designed for static high-voltage distribution. Individual ignition coils on each of the spark plugs ensure perfect ignition every time. The individual ignition coils are controlled directly by the engine electronics. Exhaust system. The exhaust system ­ with twin tailpipes on the Cayman S ­ is made of stainless steel. Until it converges in the connecting tube, the exhaust gas is channelled through two separate tracts and, thanks to separate exhaust gas cleaning systems, the exhaust gas can flow more freely ­ for increased power and torque. The stereo lambda control circuitry controls and monitors each cylinder bank separately. For each exhaust tract, four corresponding oxygen sensors regulate the composition of the exhaust gas and monitor the conversion of pollutants in the catalytic converters. A sports exhaust system ­ for a more resonant sound ­ is available as an option for each of the new Cayman models. Why? Because a Porsche belongs on the road, and not in the workshop. With the sole exception of the spark plugs, the ignition system is also maintenance-free. The alternator, power-steering pump and the air-conditioning Put simply, we don't expect to see your Porsche too often. Servicing. It is a good idea to have your vehicle serviced regularly, but it makes just as much sense to keep the time between maintenance services as long as possible. compressor are all driven by a single self-adjusting belt.

Transmission. This double clutch provides an alternating, non-positive connection between the two half gearboxes and the engine by means of two separate input shafts (input shaft 1 is nested inside the hollowed-out New Porsche Doppelkupplung (PDK). The optional Porsche Doppelkupplung (PDK), with both manual gearshift and an automatic mode, enables smooth gear changes with no interruption in the flow of power. This results in significantly faster acceleration and lower fuel consumption, without having to sacrifice the ease of automatic transmission. has a long ratio and helps to reduce fuel consumption even further. input shaft 2).

The 7th gear boxes in one and thus requires two clutches ­ designed as a double wet clutch transmission. one half gearbox and one clutch at a time, while the next gear is preselected in the second half gearbox. During a gear change, therefore, a conventional shift no longer takes place. Instead, one clutch simply opens and the other closes at the same time. Gear changes can therefore take place within milliseconds. Clutch 1 controls the first half gearbox, which contains the odd gears (1, 3, 5, 7) and reverse. Clutch 2 controls the second, which contains the even gears (2, 4, 6).

The crankshaft transmits engine torque to the dual-mass flywheel which is then channelled through the clutch housing and onto the multi-plate clutches, or to be more precise, the outer disc carrier. with input shaft 1. The torque is now transmitted through the differential to the rear axle. The non-positive connection with input shaft 2 is established, and power is transmitted to the wheels. The gear which is engaged is The advantages over a fully manual transmission are very rapid gearshifts with no interruption in the flow of power, which result in a considerably faster rate of acceleration for the same rate of fuel consumption. The advantage over a fully automatic transmission is the perceptible increase in driving dynamics ­ with a similar level of comfort, and a distinct reduction in fuel consumption. The compact dimensions of the gearbox reduce rotational masses which means a more direct engine response, and the system is more lightweight. With the optional Sport Chrono Package, PDK is enhanced by the `Launch Control' and `motorsport-derived gearshift strategy' functions (p. 62). At this stage, PDK has already preselected the next gear. Engine torque is already acting on the other outer disc carrier and, in response to a gear change signal, the overlap shift is initiated, i.e. displayed on the instrument cluster. Depending on the gearshift programme, the gear change is optimised for comfort or for sporty handling and takes place in a matter of milliseconds. This, along with the long-ratio 7th gear, helps to achieve reduced fuel consumption and emission figures comparable with those of a manual gearbox. In essence, PDK combines sportiness with efficiency and comfort. What does all this mean for you? Exactly what you would expect: uninterrupted driving pleasure. Under oil pressure, clutch 1 closes and forms a frictional connection as clutch 1 opens, clutch 2 closes. 50 51 Cayman | Drive Three-spoke sports steering wheel with gearshift switches Gear selector for PDK Gear lever in carbon Three-spoke sports steering wheel with gearshift switches. In conjunction with the optional Porsche Doppelkupplung (PDK), the standard three-spoke sports steering wheel has two ergonomic switches. Gear selector for Porsche Doppelkupplung (PDK). The gear selector for PDK impresses not only with its unique design, but above all with its superior functionality enabling you to change gear manually. The control concept mirrors the Even if the gear selector is set to automatic mode, you can still change gear manually using the switches on the steering wheel. Six-speed manual gearbox. Fitted as standard in each of the Cayman models is a six-speed manual gearbox. The shift throw is short and precise, the tuning is sporty ­ as befits the character of the new Cayman models. The dual-mass flywheel minimises engine noise and the control cable mechanism prevents vibrations from being transmitted to the gear lever. Hill-start assist. Hill-start assist comes as standard for manual and Porsche Doppelkupplung (PDK) transmissions. It assists the driver in making a comfortable, smooth and roll-free start on an incline. The system automatically detects that the vehicle has been braked to a halt on an incline. Provided a gear is engaged, the brake pressure is maintained at all four wheels for approximately two seconds once the footbrake is released. The vehicle is therefore temporarily prevented from rolling backwards. Brake pressure is reduced if, within two seconds, sufficient revs have been generated by the driver depressing the accelerator pedal (or, in the case of manual transmission, the accelerator pedal is depressed and the clutch is engaged). One press with the thumb and PDK shifts up. One pull with the index finger and PDK shifts down. Either the right or left hand can be used. logic of the switches on the three-spoke sports steering wheel ­ press forwards to shift up, pull backwards to shift down. 52 53 Chassis It's not always better to take the direct route. If you have a spirited nature like the new Cayman models, you will need a chassis that can cope with the challenges of the road ahead ­ and master them with precision. How is this achieved? All components must be the perfect match. There's only one goal: to be able to fully express one's desire for performance. 54 55 Cayman | Chassis Lightweight spring-strut front axle on the Cayman S Lightweight spring-strut rear axle on the Cayman S An expression of agility on the road that is bound to leave you open-mouthed. Chassis. The new Cayman models follow a clear line. Their own. Even when it comes to the chassis. The driver's connection to the road is an essential priority at all times, along with the delivery of the engine's power. and the anti-roll bar unit have been further tuned for exceptional driving dynamics and greater Thanks to the mid-engine layout and the construction of the bodyshell, roll and pitch are practically eliminated. The chassis responds with absolute precision to acceleration and braking. The lightweight construction keeps the vehicle gross weight and the weight of the unsprung masses low. Virtually all moving axle parts are made of aluminium. Driving stability is excellent, even in the event of considerable load changes ­ thanks not least to the vehicle's generous track width. High levels of safety and a consistently dynamic driving experience are the result. For this reason, the new Cayman models are equipped with a lightweight suspension with transverse links and spring struts, front and rear. The spring and damper unit driving comfort. During fast lane changes and through tight corners, this chassis is in its element. 56 57 Cayman | Chassis Steering. What use is a perfect suspension setup without perfectly tuned steering? For Porsche, this would be inconceivable. The solution is a steering system that works with as much precision and immediacy as the chassis itself and, thanks to the power assistance, steering effort is reduced to a comfortable level. Around the straight ahead position, such as during motorway driving, the ratio is less direct with no loss of agility or feedback. The greater the steering angle, the more direct the steering ratio. This is particularly noticeable through tight bends and when parking and provides a high level of active safety and a more immediate driving response. The car has a turning circle of just 11.1 m. The steering wheel also adjusts for height and reach. For further details about available steering 17-inch Cayman II wheel wheels, please see page 81. Cayman S 18-inch Cayman S II wheel Wheels.

The system now updates even faster after an engine start, tyre pressure correction or wheel change ­ for increased comfort and safety. Tyre Pressure Monitoring (TPM). The latest optional Tyre Pressure Monitoring (TPM) sends warnings to the on-board computer's display screen in the event of low tyre pressure. The driver can check the pressure in all four tyres from the 58 59 Cayman | Chassis Porsche Active Suspension Management (PASM). The optional PASM is an electronic damping control system. On the new Cayman models, the suspension has been tuned to match the increased power of the engine. PASM actively and continuously regulates the damping force for each wheel according to the road conditions and driving style. In addition, the suspension is lowered by 10 mm. Sensors monitor the movement of the vehicle body, for example, under heavy acceleration and braking or on uneven roads. The control unit tunes the dampers to the optimum hardness for the selected mode to reduce roll and pitch still further and to increase contact between each individual wheel and the road. Mechanically locking rear differential. Are you a fan of sporty driving? In your spare time, do you enjoy the occasional outing on the racetrack? Then you shouldn't do without the new optional mechanically locking rear differential available in conjunction with 18-inch or 19-inch wheels. In `Sport' mode, the suspension is set to a harder damper rating. On uneven roads, PASM immediately switches to a softer rating within It further enhances the traction of the driven rear wheels on uneven roads and when accelerating out of tight bends, and the damping of load-change reactions during fast cornering are reduced. Road holding at the limits of performance is even more impressive. The car holds its course better and so PSM intervenes less often. Compression in `Normal' mode ­ working piston and bypass, sportycomfortable tuning Rebound in `Sport' mode ­ working piston only, sporty-comfortable tuning The driver can select between two different modes: `Normal' which is a blend of performance and comfort, and `Sport' where the setup is much firmer. Depending on the mode selected, therefore, PASM is sportier or more comfortable than the standard chassis. The PASM control unit evaluates the driving conditions and modifies the damping force on each of the wheels in accordance with the selected mode. the `Sport' setup range, thereby improving contact between the wheels and the road. When the road surface improves, PASM automatically reverts to the original, harder rating. If `Normal' mode is selected and the driver's style becomes more assertive, PASM automatically switches to a harder rating within the `Normal' setup range. Damping becomes harder, and driving stability and road safety are increased. In other words, sheer driving pleasure and faster lap times.

Do you think driving a Porsche should be an even more involving experience than it is already? Your wish is our command. On request, we can equip your vehicle with the Sport Chrono Package, which is available for both of the new Cayman models. Its functions enable even sportier tuning of the engine and chassis and guarantee even more driving pleasure. immediate, adjusts the rev-limiter to a harder setting, tunes the engine dynamics for performance driving and activates the optional sports exhaust system. tion, the system initiates a swifter, brake-induced downshift. In manual mode, gear changes are faster and more dynamic. In `Sport' mode, the PSM system (p. 72) intervenes later for increased longitudinal possible rate of acceleration from a standing start ­ on the racetrack, for example. `Launch Control' is operated via the Sport Plus button with the `D' or `M' drive position selected. Whilst the driver depresses the brake pedal with the left foot, the right foot depresses the accelerator pedal to the floor. With the accelerator in the kickdown position, the system detects the driver's request for Launch Mode and revs the engine to an optimum speed of approximately 6,500 rpm. Engine torque increases and the clutch closes slightly. The message `Launch Control active' appears Sport Chrono Package Plus. Comparison of the ETC characteristic curve in `Normal' mode and `Sport' mode On request, the new, optional Porsche Communication Management (PCM, p. 92) can be combined with the Sport Chrono Package Plus. In addition to the functions of the Sport Chrono Package, it includes a personal memory function, which can be controlled using PCM, and a performance display for evaluating lap times. The optional Porsche Active Suspension Management (PASM) also switches to `Sport' mode, which offers harder damping and more direct steering and, therefore, better road holding. and lateral dynamics. PSM now affords greater manoeuvrability under braking and exit acceleration, especially at low speeds. For maximum dexterity, PSM can be set to standby while the car is still in `Sport' mode (p. 72). For safety, With the optional PDK in automatic Selecting the `Sport' button on the centre console activates `Sport' mode, which makes throttle response significantly more mode, gearshift points are delayed until the upper rev range.
