Porsche Cayman S

From Porsche press:  Porsche is presenting the second generation of the mid-engined Cayman sports coupe at the Los Angeles Motor Show (November 21 – 30) this week. The highlight is the new, flat-six ‘boxer’ engines, developed to incorporate new technical features from the ground up, providing not only more power, but also significantly greater fuel efficiency.

A further improvement of both fuel economy and performance is guaranteed by the Porsche Doppelkupplungsgetriebe (PDK), the new double-clutch gearbox now available as an option on both the Cayman and 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.

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.

While instantly recognisable as a Porsche sports car, the Cayman is individual in its design. Originally launched in 2005, the characteristic silhouette of the Cayman has remained fresh and contemporary. Its distinctive coupé lines are combined with a long wheelbase and a rear aspect that slopes gently downwards. From the rear, the Cayman is defined by a large, opening rear lid, powerfully sweeping wheel arches and an automatically extending spoiler.

The rear lid opens upwards to provide access to the 260 litre luggage compartment. This, in conjunction with the 150 litre capacity luggage compartment in the nose, plus numerous additional storage compartments, ensures that this two-seater sports car combines real functionality with elegant aesthetic form.

As is Porsche tradition, the styling of the next generation two-seater Coupe has evolved subtly. However, it is clearly distinguishable from outside through its newly-designed nose and tail. The new halogen headlights with their integrated direction indicators are reminiscent of the lights on the Carrera GT, and the new LED rear lights tapering to the outside are integrated elegantly in the remodelled bodywork.

The rod-shaped side lights in LED light conductor technology add distinction to the car’s looks, which are further enhanced through their horizontal arrangement in the outer air intakes. Yet a further highlight is provided by the round fog lamps featured as standard. 

For the first time the Cayman is available with a Lights Package featuring bi-xenon headlights, dynamic cornering lights and LED day-time driving lights. Replacing the fog lamps, these light units are made up of four LEDs arranged in round light units like the eyes on dice.

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.
