We’re behind the driver 100 percent. Or in this case, about 12 inches.
Boxer Engines
The new Cayman models are powered by compact, mid-mounted boxer engines positioned no further than 12 inches behind the driver. This unorthodox approach yields unique attributes. A substantial amount of the weight of the Cayman is concentrated close to the middle of the vehicle. The center of gravity is low and central, and weight is distributed uniformly between the front and rear axles. The tangible effect—a truly stunning level of agility, with well-balanced handling, particularly in corners.
The new engine concept is defined by high power plus reduced fuel consumption and emissions figures compared with 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 with 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 Cayman driving experience? Direct responses to every burst of acceleration. Dynamic handling in every corner. Oh yes, and one more thing: the inevitable pain of separation at the end of every drive.
2.7-Liter Engine
The Cayman model is equipped with a free-revving 2.7-liter flat-six engine with Direct Fuel Injection (DFI) and VarioCam Plus. It develops 275 horsepower at 7400 rpm. The maximum torque of 213 lb.-ft. is available across a wide speed range from 4500 to 6500 rpm.
The new Cayman with six-speed manual gearbox accelerates from 0–60 mph in 5.4 seconds and reaches a top track speed of 165 mph. With the optional Porsche Doppelkupplung (PDK), it completes the 0–60-mph sprint in 5.3 seconds and achieves a maximum track speed of 164 mph. Available as an option, the Sport Chrono Package offers a further performance boost, enabling the new Cayman to accelerate from 0–60 mph in just 5.1 seconds.
3.4-Liter Engine
The new Cayman S draws its agility from a 3.4-liter flat-six engine with Direct Fuel Injection (DFI) and VarioCam Plus. It produces 325 horespower
at 7400 rpm and its maximum torque of 273 lb.-ft. is generated between 4500 and 5800 rpm. The new Cayman S with six-speed manual gearbox races from 0–60 mph in 4.7 seconds and reaches a top track speed of 175 mph.
Even sportier figures are achieved with the optional PDK: 4.6 seconds from 0–60 mph and a top track speed of 174 mph. In conjunction with the Sport Chrono Package available on request, the new Cayman S finishes the sprint to 60 mph in just 4.4 seconds.
Resonance Intake Manifold
The new boxer engines benefit from the resonance effect. It’s used to oscillate the air mass inside the intake manifold for improved air induction. In turn, it helps optimize the formation of the air/fuel mixture. In the Cayman S, the manifold is also equipped with a switchable resonance valve.
The results are high torque, a uniform torque curve, and high power output. The sound produced is characteristically resonant and deep.
Direct Fuel Injection (DFI)
In both new Cayman engines, Direct Fuel Injection (DFI) is standard. Multi-hole injectors deliver fuel directly into the combustion chamber with 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 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
By adjusting the intake camshafts and switching the lift of the intake valves, VarioCam Plus transforms the characteristics of the engine. So much so, it’s like getting two engines in one.
The system first differentiates between driver inputs that typify normal, everyday driving and those inputs that demand maximum performance. The electronic engine management system then imperceptibly adapts valve operation to the prevailing conditions. This results in instant acceleration and extremely smooth running.
In short, VarioCam Plus provides excellent acceleration power with comparatively low fuel consumption.
Integrated Dry-Sump Lubrication
A reliable oil supply is the lifeblood of a performance engine. In the new Cayman and Cayman S, the engines are supplied oil via integrated dry-sump lubrication. It 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 emissions levels.
Efficiency Technologies
Heat is the enemy of performance. 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 results in more efficient 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, originally developed for Porsche race cars to fight the extreme temperatures encountered in endurance races, supplies each engine cylinder uniformly with coolant. It protects all valves against thermal overload and premature wear. This helps improve combustion and helps keep emissions, fuel consumption,
and noise comparatively low.
Exhaust System
In the new Cayman models, each cylinder bank has its own stainless steel exhaust tract. Downstream of their respective rear silencer, the tracts converge in a connecting tube and a single (Cayman) or twin (Cayman S) tailpipe. The stereo lambda sensor 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 new Cayman models is the sport exhaust system including Sport tailpipe. It produces an even more resonant Porsche sound.
