Porsche checking fluids

In order to avoid big, expensive problems, you should check
under the hood of your Porsche on a regular basis. By following
these simple monthly checks you will find and solve these potential
problems.

First of all, you should check the oil, but only when the engine is warm.
That’s because it expands when it’s hot and contracts when it’s cold;
different temperatures will give you different readings. And since you’re
already checking the fluids you should also check the
brake fluid. It’s easy to do and only takes a minute.

Radiator fluid, or coolant, is the most important part of your Porsche’s
cooling system, which protects your engine from overheating. Low
coolant can lead to a breakdown and expensive repairs. Before
checking the power steering fluid (which is also easy on most cars)
you should see if you have it. Try to parallel park with one hand and
eat an ice cream cone with the other. If you can do that, then you have it.

If you have an automatic transmission, you’ll want to check the
automatic transmission fluid (ATF) every month. Also, if your Porsche
has a hydraulic clutch that connects the clutch pedal to the
transmission, you should check that fluid too.

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 engine, 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 milliseconds. 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 managing 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 returnless
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.

Porsche 968

Porsche 968 is basically the successor of the Porsche 944.
It has a low nose and wide wheel arches that helps accentuating
the beautiful lines of this classic shape that in a Porsche Guards
Red is a real head turner. It has also the classic GT front engine,
rear wheel drive layout with the added advantage of a rear transaxle
giving almost perfect weight distribution.

Instead of the hidden headlights of the 944, the 968 has visible
pop up headlights, similar to the Porsche 928. This brings the
look of the car inline with the new Porsche 997-911. This change
has also a practical advantage: the headlights can be washed
along with the rest of the car instead of having to pop them up to
wash them.

As for the interior, it remains the same as produced in the 944,
keeping the famous “oval dash”. The designers used the same
robust materials which have given all Porsche owners many years
of trouble free motoring.

The exterior has a few differences: the door mirrors have
been streamlined with the tear drop effect and the wheels
have 5 spoke Cup design alloys. The rear bumper is more
blended and with integral rear light clusters, making it almost
indistinguishable from the bodywork. All these bodywork changes
made the 968 look a lot like the 928, and added the engine heritage,
some people have referred to it as “the daughter of 928″.

The engine is a version of the one first used on the 944 S2: it is a
4 cylinder, 3 liter, 16 valve unit. And they added VarioCam for
optimum power throughout the speed range. It has 240 HP
at 6200 rpm and a torque of 305 Nm at 4100 rpm, given by the
improved combustion chamber and inlet manifold design. At the
time of production, it was a remarkable engine, having the highest
displacement per cylinder of any car engine and also the highest
torque output of any unblown 3 liter engine. Clearly, the result of
Porsches investment in this engine paid off.

The rear-mounted gearbox is a 6-speed manual or 4 speed tiptronic.
It is the first ever mounted on a production car. The chassis has
almost perfect weight distribution and very stiff characteristics.

Usually, most cars start to fail when it comes to breaks and the
reason is that it doesn’t matter how fast the car is in a straight
line if you can’t take a bend (turn) at the right safe speed. But Porsche
brakes have always been the envy of most road sports car
manufacturers. You will notice little or no or no discernable fatigue
even under harsh use of Porsche 968. ABS adds even more
safety to the already excellent braking system. Also, what makes
the brakes so effective is that the wheels themselves are designed
to prevent the tire from coming off the rim in the event of a sudden pressure
loss.

Porsche 977 bodyshell

A new Porsche 911 is always fascinating because it’s interesting
to see how after more than 40 years of development the Porsche
team still manages to bring changes and improvements to this
icon model.

The new 997 bodyshell combines the sleek modern looks of
the 996 series with the popular retro styling cues from older 911s.
The front end is completed with round lights and separate
parking/fog/indicator lights. This change, combined with wider
hips echoes the last of the air-cooled 911s, the 993. Other changes
in the bodyshell are the new door handles, wing mirrors and the
stylish cut of the rear wings into the bumper/lights.

Even if the 997 looks a lot like the previous model, the 996, the new
car is actually 38mm wider which creates a more aggressive
appearance. With each new model introduced, Porsche has aimed
to reduce the drag co-efficient helping the 911 slide through the air
more effectively, and so aiding performance. The same thing has been
done with the new car, and if we compare the 993 Cd of 0.34 to the
997`s 0.28 we can see how far the aerodynamic game has moved on.
The latest body shell and rear wing combine with new underbody
paneling to also offer increased levels of down force for this latest
evolution of Porsche’s finest.

The latest Porsche model is the best handling 911 ever. Improving a
car’s rigidity helps ensure the suspension can work more effectively
and while not making such a quantum leap as the team did with the
996. Porsche improved torsional rigidity by 8% and added as much
as 40% more flexural strength.

For the new car, Porsche wanted to improve crash safety so they
added two new air bags located in the side of each front seat back-rest,
designed to protect the thorax. They kept the previous two front and two
side airbags, which means that now there are six in total. For the same
reason, crash safety, the reinforced body shell features further protection
such as a more extensive use of super high strength steel.

The latest model is also 50 kg heavier than the 996. The reason is that
modern crash safety regulations kind of force the new cars to come with
increased weight, despite the usage of a large range of weight saving
measures, including an aluminum bonnet.

Aside from the crash safety improvements, much of the additional weight
can be attributed to the higher standard specification of the new cars.
Power to weight is similar with the latest car offering 233 bhp per tone
against it’s predecessors 238 and the new models improved aerodynamics
must help it post Porsches claimed performance figures, which are
identical to the 996.

Porsche the beginning

It`s hard to say exactly which is the beginning of Porsche
story. It could be in 1950, when the famous Max Hoffman
introduced the Porsche 356 to the United States. Or in 1948
when the first automobile to bear the name Porsche was introduced.
But in order to understand Porsche’s heritage and its philosophy
we need to go back to 1875, when, in September, at the home
of a tinsmith in the Bohemian village of Haffersdorf, a son was
born. His name was Ferdinand Porsche.

Since his adolescence, Ferdinand Porsche showed glimpses of
technical genius: at the age of 18, he wired family’s home for
electricity in 1893. Still, he didn’t show many signs of disciplined
engineering skills that will eventually become his trademark. Even
if the “Doctor” is usually appended to his name, it is in essence
honorary, since his only formal technical training was as a part-time
engineering student in Vienna.

By the age of 25, the young Ferdinand Porsche had entered the
field of automotive design. His first car design was already
accepted by Lohner & Co. of Vienna. Over the next 20 years,
Ferdinand Porsche, the temperamental but brilliant engineer
succeeded in associating with every major automobile manufacturer
in Germany. At the same time, he designed a dozen of the most
technically significant cars in history.

Working for Mercedes-Benz, he helped develop the most revered
Mercedes-Benz cars of all time: the SSK series. For NSU, he
designed Auto Union Wanderer and the Type 32, a precursor of the
Volkswagen Beetle.

After being dismissed from Mercedes for disagreeing with the firm’s
staid engineering policies, Porsche decided to establish what later
became Porsche A.G.: his own engineering consulting group. In a
small office in Stuttgart, the senior Dr. Porsche gathered a select
group of engineers to work under the dramatic name, “Doctor of
Engineering Ferdinand Porsche, Inc., Construction Facility for Land,
Air, and Sea Transportation.” One of his employees was his youthful
son, Ferry. His primary interest was one that any young man might
select: sports and racing cars

The senior Dr. Porsche and his team were kept extremely busy. The
consulting firm developed for Steyr (now the utility-vehicle wing of the
Steyr- Daimler-Puch combine), the Austria luxury sedan, but it did not
progress beyond the prototype stage. They worked a lot for Auto
Union, now Audi: the company developed the Front, the world’s first
front-drive economy car. They astonished Auto Union with the mid-engine
Grand Prix cars and their supercharged V-12 and V-16 engines
which, together with Mercedes- Benz racers, dominated European auto
racing for nearly a decade.

After that, the firm created its best-known designs for NSU and Zundapp.
The pair of prototypes was characterized by Dr. Porsche’s patented
torsion-bar suspension and a rear-mounted engine. Since neither
company moved rapidly enough to manufacture the designs, Porsche
sold the concept to the German government. Then, he oversaw the
construction of a plant on Wolfsburg to manufacture the design. His
drawings called the car the Type 60. The world came to know it as the
Volkswagen Beetle

After the second World War, the Porsche Company started to create vehicles
that beard its name, and so became knows world wide. Now, nearly a
century later, Porsche became the marque and the family that created
outstanding, often unique and surely lasting contributions to automotive
engineering and design.
