The Porsche Boxster

Post by LhYnxz on Fri Jan 25, 2008 5:12 pm



Designed and developed by Porsche engineers
in just three and one half years, the Boxster is a thoroughbred two seat
roadster. The basic philosophy in developing the Boxster was to make the
car a genuine Porsche in every respect. And the company's designers have
fulfilled their task perfectly. In its styling and design,
the body is a modern interpretation of Porsche's classic models from the
past. It proudly boasts styling features carried forward from the immortal
Porsche No. 1 built in 1948 and the 1953 Porsche 550 Spyder.

Still, the Boxster seeks not only to
thrill the beholder through its styling, but is also a good example of
modern body design. With a drag coefficient of just 0.31 as well
as lift forces on the front and rear axles reduced to a minimum, the Boxster
sets new standards also in terms of aerodynamics.

Another unique feature of the Boxster
is that it opens up Porsche's price segment at the lower end, offering
genuine Porsche motoring at a price never seen before. This achievement
is made possible by consistent application of the simultaneous engineering
principle and a totally new production concept now applied by the Company.
Indeed, production of the Boxster sets a new standard in modern, rational
production philosophies, suppliers being fully integrated in the production
process through a new concept of cooperation giving them greater responsibility
for their supply modules and components.

In its technical concept the Boxster
again takes up an old Porsche heritage by re-introducing the mid-engine
concept. Even the very first Porsche built, the 356/1 prototype,
came with its engine in midship arrangement. And the most successful Porsche
in the company's early years, the 550 Spyder, applied the same principle
characteristic to this day. The Porsche Boxster proves that mid-engine
design is perfectly suited for sports cars with everyday driving qualities.







In developing the soft roof, Porsche's
engineers made it their commitment from the outset to reduce wind noise
to a minimum. Another unique feature is that it takes only 12 seconds to
open and close the roof electrically by way of a toggle switch - a function
only possible, for safety reasons, with the car at a standstill and the
handbrake on.

And last but certainly not least, the
special sealing and water deflection system on the roof efficiently prevents
even the slightest moisture from getting inside the car. Despite substantial
experience from motor racing in the use of aluminum and plastic materials,
Porsche's engineers opted for classic steel plate in building the fully
galvanized bodyshell of the Boxster.

The interior offers all the features
typical of a Porsche in even younger, more up-to-date style, and naturally
includes two airbags. Following an old tradition of the company,
the ignition lock remains on the left-hand side while the instrument panel,
as a whole, is far more compact than before with its three main instruments
placed conveniently right in the middle.

The Boxster is available with two types
of seat, both with electrical backrest adjustment: either the sporting
but comfortable standard seat or the sports seat with even better support
at the side. Apart from various options, the Boxster may also
be refined to an even higher standard with the Sports package comprising
17-inch wheels, an even lower suspension, and traction control.

The engine of the Boxster is brand-new
in every respect. While naturally being a "classic" Porsche power unit
in flat-six configuration, it has obviously been updated to reflect the
signs of the times, now featuring a water cooling system and four-valve
technology.

These systems, which really reached
maturity in the 911 GT1 racing car, help the regular production Boxster
to minimize both fuel consumption and exhaust emissions. And with an output
of 150 kW or 204 bhp at 6000 rpm, the engine ensures ample power and performance
from
its 2.5 litres.

In the design of the six-cylinder horizontally-opposed
power unit Porsche's engineers have again established several new benchmarks.
The flow of coolant is the same as on Porsche's racing engines, applying
the cross-flow principle to keep all cylinders and combustion chambers
at the same, consistent level of temperature.

There is a separate coolant circuit
around the cylinders as opposed to the cylinder heads. bridge. Camshaft
opening times are kept variable by adjusters in the drive chains (applying
Variocam, a Porsche patent). Featuring automatic chain tensioners and hydraulic
play compensation, the entire valve drive system is absolutely maintenance
free.

Fuel injection and ignition are both
masterminded by Bosch Motronic M 5.2. Fuel supply is sequential through
one jet per cylinder, meaning that it follows the same rhythm as the firing
order of the engine. The amount of fuel injected per cycle is determined
by hot film air mass metering in the intake manifold and, of course, by
oxygen sensors featuring particularly accurate stereo control.

The ignition system is all-electronic,
featuring solid-state technology and six individual coils without any mechanical
ignition components or distributors. To adjust the engine to fuel grades
inferior to 98 RON SuperPlus, the electronic ignition control unit incorporates
cylinder specific anti-knock management retarding the ignition on a cylinder
about to knock.

Focusing on the power transmission
of his car the Boxster purchaser has the choice of either a five-speed
manual gearbox or, at extra cost, five-speed automatic transmission.

The Tiptronic S transmission on the
Boxster differs from its counterpart in the 911 not only through the number
of gears, but also through the configuration and use of the selector lever.

Featuring wheel supports and guidance
components made of aluminum, the suspension of the Boxster is truly progressive.
By consistently using standard parts common to the Boxster and the 911,
both axles, based on the McPherson principle, offer an economic and, at
the same time, compact, space-saving solution.

The brake system incorporates the latest
achievements in racing technology, with the Boxster being the first production
car to feature light alloy, four piston brake calipers in monoblock design.
These extra strong multi piece calipers come straight from the 911 GT1
and are also used in Formula 1. The brake discs are inner vented
front and rear, and the anti-lock brake system (ABS 5) is fitted as standard.
