Porsche Cayenne.


                                      Porsche Cayenne.

The Porsche Cayenne entered the market with mixed anticipation. However, it soon proved that it was the performance vehicle among SUV's and was praised for its excellent handling and powerful engines.The lineup initially consisted of the V8-powered Cayenne S and Cayenne Turbo. Later in the model cycle, VR6 and diesel-powered versions joined the lineup.

The Cayenne models that are equipped with eight-speed Tiptronic S also feature an Auto Start Stop function. If for example you stop at traffic lights and keep your foot on the brake pedal, the Auto Start Stop will automatically turn off the engine. Although the engine is not running, all audio and communication systems remain switched on and the standard climate control continues to maintain the selected temperature. The only changes you’ll perceive: peace and quiet and – thanks to greater fuel economy – also peace of mind.
On all Cayenne gas engines we have used direct fuel injection (DFI) to achieve a significant increase in specific power and torque as well as better fuel economy and lower emissions.

The Cayenne features a naturally aspirated 3.6-liter V6 engine with direct fuel injection (DFI) and variable valve timing on both inlet and exhaust. The unit delivers 300 hp at 6,300 rpm and maximum torque of 295 lb.-ft. at 3,000 rpm. Maximum top track speed is 142 mph. The car requires 7.1 seconds to reach 60 mph with a manual gearbox.

The V8 engines have an enhanced coolant management system offering effective temperature control throughout the engine. While 20 percent of coolant flows longitudinally through the crankcase, the remaining 80 percent serves the cylinder heads using the proven cross-flow principle (from hot to cold).
On all Cayenne models, the piston heads are cooled using oil-spray jets integrated within the main lubrication system. The V8 engines use dry-sump lubrication to ensure a consistent supply of oil in all load conditions, especially in off-road terrain. The oil reservoir is located inside the engine. This saves on space and reduces weight.

Oil is circulated around the V8 engines using a demand-driven pump. This has been designed for the toughest driving scenarios on and off road, including performance driving and extreme gradients.
The V6 engines have a wet-sump lubrication system. Ensuring a reliable supply of oil, whatever the driving conditions.

We’ve just continued to improve it the Cayenne is now lighter up to 363 pounds* depending on the specification and also more dynamic more comfortable and closer to the road than ever before. Without detracting from the qualities required for off-road driving or towing heavy loads.
