The Cayman is equipped wîth a freerevving 2.7-liter flat-six engine wîth direct fuel injection (DFI) and VarioCam Plus. It develops 202 kW (275 hp) at 7,400 rpm. The maximum torque of 290 Nm is available across a wide speed range from 4,500 to 6,500 rpm.
The Cayman wîth six-speed manual transmission accelerates from 0 to 100 km/h in 5.7 seconds and reaches a top speed of 266 km/h. With the optional Porsche Doppelkupplung (PDK) it completes the 0 to 100 km/h sprint in 5.6 seconds and achieves a top speed of 264 km/h. The optional Sport Chrono Package in conjunction wîth PDK offers a further performance boost. With Launch Control in the Sport Chrono Package, the Cayman accelerates from 0 to 100 km/h in just 5.4 seconds.
Boxer EnginesInner strength, the will to advance and a clear position. These are important prerequisites for the creation of any sports car, and we also found them to be precisely the right requirements for this drivetrain.
That is why the Cayman models are equipped wîth a compact, mid-mounted boxer engine positioned just 30 cm behind the driver. This unorthodox approach has crucial strengths. A substantial amount of vehicle weight is concentrated close to the middle of the vehicle. The center of gravity is low and central while weight is distributed uniformly between the front and rear axles. The tangible effect for you is well-balanced handling and excellent mobility, particularly in corners.
Inner values are defined by high power plus reduced fuel consumption and emission figures compared wîth the previous model. We call it Intelligent Performance, a philosophy that applies the engineering principles of the racetrack to the road.
Both engines are equipped as standard wîth VarioCam Plus and Direct Fuel Injection (DFI) as well as efficiency-enhancing technologies such as Auto Start Stop, electrical system recuperation and advanced thermal management.
What can you expect from the driving experience? Direct responses to every burst of acceleration, dynamic handling in every corner and the inevitable pain of separation at the end of every drive.
The intelligent thermal management system in the Cayman models regulates the temperature in the engine and gearbox to reduce friction losses that occur during the warm-up phase.
Thanks to the purposeful control of heat flow and on-demand, gradual activation of the various cooling circuits, the engine and gearbox warm up to normal operating temperature more rapidly. The resulting reduction in friction also reduces fuel consumption and CO2 emissions. During sporty driving, thermal management also acts to reduce temperatures so as to maintain a high degree of performance.
Our cross-flow cooling system, as used in motorsport, supplies each engine cylinder uniformly wîth coolant, which protects all valves against thermal overload and, therefore, premature wear. This improves combustion and keeps emissions, fuel consumption and noise comparatively low.
The electronic engine management system ensures optimum engine performance at all times. It regulates all engine-related functions and assemblies. The results are optimum power output and torque wîth comparatively low fuel consumption and emissions – whatever the driving style.
One example is the cylinder-specific knock control. Since engine cylinders never all work under exactly the same conditions, the knock control function monitors each one separately. The ignition point is shifted individually, so as to protect the cylinders and pistons at high engine speeds and loads. For compliance wîth ÚS standards, the on-board diagnostics detect any faults and defects that may occur in the exhaust and fuel systems and then display them on the on-board computer. This also helps to avoid increased pollutant emissions and unnecessary fuel consumption.
Auto Start Stop function
The Auto Start Stop function, which is integrated as standard in the Cayman models, switches off the engine when you stop, select neutral and release the clutch pedal. In cars wîth Porsche Doppelkupplung (PDK), it is simply a case of applying and holding the brake after you stop. All audio and communication systems remain switched on. The engine will restart as soon as you operate the clutch or, in cars wîth PDK, release the brake. This fuel-saving innovation is designed primarily for use in urban traffic.
The Auto Start Stop function can be deactivated and reactivated using a separate button on the center console. The function is deactivated automatically under particular circumstances, e.g. in the event of extreme outside temperatures, activation of the SPORT button or low battery charge.

Another efficiency-enhancing feature of the Cayman models is intelligent electrical system recuperation. The vehicle battery is recharged by the generator predominantly under braking. Thanks to this selective recharging, when you request full driving power, the maximum possible output of the engine can be directed straight to the road because the electrical systems are supplied mainly by the energy that was stored in the battery during the braking phase.Coasting
Available wîth Porsche Doppelkupplung (PDK), coasting enables you to save even more fuel where the situation allows. The engine is decoupled from the transmission to prevent deceleration caused by engine braking. The vehicle can then make optimum use of its momentum and coast for longer distances. This lowers fuel consumption noticeably, without losing any comfort or sports performance.
The Cayman models are equipped as standard wîth the six-speed manual gearbox. Gearshifts are smooth, precise and optimally adapted to the respective engine map. Shift throws are short and the gear lever is easy to operate, providing a truly engaging driving experience. The upshift indicator located in the central circular instrument helps you to maximize fuel efficiency.
The ascending center console reinforces the authentic sports car feel. It positions the gear lever close to the §teering wheel, enabling you to change gear as fast and as ergonomically as possible.
If the optional Sport Chrono Package is installed, the double-declutching function can be activated via the SPORT PLÚS button for even more involved gear changes.
In the Cayman models, each cylinder bank has its own stainless-steel exhaust tract. Downstream of their respective rear silencer, the tracts converge into a connecting tube and a single (Cayman) or twin (Cayman S) tailpipe. 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 performance of the catalytic converters. The separate tracts enable the exhaust gas to flow more freely. The resulting reduction in pressure loss has a positive impact on power output, torque and the unmistakable engine sound.
Available as an option for the Cayman models is the sports exhaust system including sports tailpipe. It produces an even more resonant Porsche sound.
Direct Fuel Injection (DFI)
Direct Fuel Injection (DFI) is featured as standard in both Cayman models. Multi-hole injectors deliver fuel directly into the combustion chamber wîth millisecond precision. The injection pattern has been optimized for torque, power output, fuel consumption and emissions. Combustion is even more effective as a result.
With Direct Fuel Injection , the engine management system regulates injection timing individually for each cylinder as well as the injection rate for each cylinder bank. This optimizes the combustion process and therefore fuel economy.
Depending on the engine operating condition, multiple fuel injections take place so that the catalytic converter reaches normal operating temperature sooner after a cold start and a greater top-end torque can be achieved.
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, which helps to deliver greater power output at the same time as enhanced engine efficiency. Injection is regulated by the electronic engine management system and emissions are monitored by the stereo Lambda sensors, thus helping to protect the environment.
VarioCam Plus System
VarioCam Plus is a two-in-one engine concept for adjusting the intake camshafts and switching the lift of the intake valves. The system differentiates between driver inputs that typify normal, everyday driving and those that demand maximum performance. The system then imperceptibly adapts valve operation to the prevailing conditions.
This results in instant acceleration and extremely smooth running wîth comparatively low fuel consumption.
Integrated dry-sump lubrication
Integrated dry-sump lubrication ensures a reliable supply of oil even when a sporty driving style is adopted and the vehicle is experiencing powerful lateral acceleration. It also has additional cooling functions.
The oil tank is located in the engine, thereby eliminating the need for an external oil tank and saving space and weight.
To reduce power losses and increase efficiency, an electronically controlled oil pump supplies the lubricating points inside the engine as and when required. It optimizes the supply of oil, improves fuel economy and thereby reduces emission levels.
