Porsche Chayenne
Ten years ago, the idea of a Porsche sport utility vehicle would have seemed absurd. And the reason is not that it lacks experience with off-road cars since their engineering have developed all-wheel-drive military vehicles.
It’s more that, compared to General Motors, Toyota or Daimler-Chrysler, the automotive giants, Porsche represents a tiny fraction of the production volume.
For 50 years, the company has produced quick, nimble, small sports car, or in other words, the opposite of the SUV’s. When Porsche decided to invest in an SUV and a new factory to build it, it became clear the times, as well as our taste, have changed.
Now, after creating the most anticipated new Porsche in decades, the company is proud that its SUV is what many expected it would be technically slick and remarkably fast, with on-road handling that belies its bulk.
Also, the Cayenne delivers what most SUV buyers demand, including decent cargo space, more than enough capability for casual off-road use, and impressive towing capacity.
When it comes to pricing, Cayenne is a true Porsche. A very expensive Porsche. With tax and license, a loaded Cayenne Turbo can crack the $100,000 barrier, and that alone will knock it off most shopping lists.
For the connoisseurs, the Porsche Cayenne will be truly appreciated for its performance and driving satisfaction.

Porsche Chayenne - the engine
With every new automobile, Porsche tried to redefine the meaning of performance, by creating a more powerful engine. Cayenne Turbo makes no exception to this rule. Like all Porsche engines, it is hand assembled and the twin turbo V8 rises to an exacting level of technical excellence.
Motronic ME7.1.1.is a system that controls the split-second precision of the Cayenne V8 and V6 super engine. This new highly intelligent engine management system balances impressive power with great smoothness.
All this to prove that Cayenne`s “brain” matches its brawn. The Motronic system is built to monitor a wide range of sensors and engine components.
It compares streams of data with corresponding sets of reference values, all this in a speed of micro-seconds. Then, if it finds any differences, the system adjusts key engine functions, such as the ignition of fuel injection, based on this comparison.
Into Motronic management are included other key systems, such as onboard diagnostics and cylinder-specific knock control, with automatic adaptation to any change in fuel quality. All this for optimal performance in all driving conditions.
This process is seamless and automatic so the engine has a great level of power and torque. Also, another great result is better fuel economy and lower emissions in the exhaust stream.
Another function of the Motronic system is the management of air flowing into the engine to ensure maximum levels of performance. It does that by regulating boost pressure on the Cayenne Turbo.
The Cayenne model includes another system. The resonance induction system with a variable-length intake manifold.
This is also an inventive engineering concept that uses pressure waves created by the inlet valves. It does this to increase the density of the incoming air, which, in the end, will increase the amount of energy released during combustion.
There are two intake tubes, and depending on the speed, the system will select one of them. The longer tube is used at lower speeds in order to maximize low-end torque.
At around 4250 rpm, it switches to shorter Intake tube so that it maximizes power output with a more eager throttle response.
The Porsche Cayenne engineers wanted to improve combustion for more power, better fuel economy, reduced emissions and less maintenance.
To do so, they created a static high-voltage ignition system with separate ignition coils on each individual spark plug. This is an advanced method that allows a longer spark-plug life.
The sequential fuel injection system is equally advanced. A non-return fuel supply system serves each injector in order to continuously adjust the precise air/fuel mix.
The result is of course a better environment, because it controls the emissions.
