Porsche 911 Targa 4, 2009

Porsche 911 Targa 4, 2009


 

The 911 Targas differ from both the Carrera Coupes and Cabriolets by dint of their stunning glass tops. The all-wheel drive Porsche 911 Targa 4 and Targa 4S are unique with roofs comprised entirely of two transparent panels. The glass extends from the windshield header back to the leading edge of the engine cover, from side frame to side frame.

More Power from Less Fuel
Both the Porsche 911 Targa 4 and 911 Targa 4S receive new engines which boast direct fuel injection, new two-piece crankcases and revised intake and exhaust systems along with Porsche VarioCam Plus intake-valve timing and lift system. By injecting the fuel directly into each cylinder's combustion chamber rather than the intake as is more common, combustion is cleaner and more complete. This technology reduces exhaust emissions and fuel consumption while simultaneously increasing engine potency.

The results are felt and appreciated immediately by the Porsche 911 Targa 4's driver. Thanks to a 6.2 percent increase in horsepower and a 5.3 percent gain torque over last year's model, the 3.6- liter engine goes from 325 to 345 hp and receives a gain in torque from 273 to 288 lb.-ft. A manual gearbox equipped 2009 911 Targa 4 can accelerate from 0 to 60 mph (96 km/h) in 5.0 seconds.

Two Clutches, No Clutch Pedal
To take full advantage of the newly designed engines, Porsche is offering drivers a transmission that delivers quicker acceleration than is possible with the standard manual gearbox while maximizing fuel efficiency. The new PDK (from the German Porsche- Doppelkupplungsgetriebe), or Porsche double-clutch, replaces the Tiptronic S as the optional gearbox in both the Porsche 911 Targa 4 and Targa 4S.

Porsche was the first automaker to successfully use this transmission technology back in the 1980s when the transmission was developed for the mighty Porsche 962 Group C race car. The Porsche 911 Targa 4 or Targa 4S driver can allow the seven-speed PDK to shift up and down automatically, or he may opt to manually shift via steering-wheel mounted paddles or the console-mounted lever, the same as with the Tiptronic S.

All-Weather Maximum Performance
In addition to their unique two-section glass roofs, the Porsche 911 Targa 4 and Targa 4S offer their drivers the added benefits of all-wheel drive. For 2009, these cars benefit from the same electronically controlled Porsche Traction Management (PTM) found under the awesome Porsche Turbo, as well as the new mchanical locking differential standard.

PTM replaces the previous models' viscous-coupling, mechanical all-wheel drive system and operates more quickly and seamlessly than its predecessor. PTM varies the torque split infinitesmely and absolutely between front and rear wheels as needed for optimum traction. However, since most purists feel-and Porsche's engineers staunchly believe-that rear-drive is critical for optimum sporty driving, PTM directs two thirds of the engine's torque to the rear wheels under normal driving conditions.

When the system determines it's needed, PTM diverts engine power and torque to the front axle in millisecond cycles. Particularly at very high speeds, all the driver feels is the car's significant stability.

Bigger, Grippier Brakes
Porsche engineers firmly believe that a car's deceleration ability must always out-perform its ability to accelerate. Commensurate with the gains in engine performance, the 2009 Porsche 911 Targa 4 and Targa 4S receive added braking capability. All four brake rotors on both cars are cross-drilled, inner vented and now 12.99 inches (330 mm) in diameter.

In addition, the monobloc, four-piston calipers are now the same as those used on the 911 Turbo. Critical refinements have been made to the airflow around the wheels to increase brake cooling all around as well.

Instantly Recognizable and Aerodynamic
With their full-glass canopy - from beltline to beltline, front cowl to rear engine cover - the Porsche 911 Targa 4 and Targa 4S look like nothing else on the road, Porsche or otherwise. But from the beltline down, the cars share a strong resemblance to the current Carrera 4 and Carrera 4S models.

Clearly, the most striking element of the 911 Targa is its 16.58 sq.-ft. glass roof. The roof is comprised of two separate segments: a sliding panel over the front seats and a hinged tailgate at the rear. The electrically operated front panel fully opens or closes in seven seconds. When open, the glass panel slides snugly beneath the tailgate, providing almost five square feet of open space above the passenger cabin.

The sliding roof comes standard with a new sun shade offering greater privacy and more effective thermal protection than before. When closed, the sun shade covers the entire area of the sliding roof panel, opening and closing electrically and independently of the roof itself.
The glass roof and tailgate are made of special tinted glass, which protects the occupants from ultraviolet radiation and excessive heat even in bright sunlight.

The rear section of the Targa top opens for access to the interior, particularly handy for getting to the storage area behind the rear seatbacks. The Porsche 911 Targa 4 and Targa 4S are the only models in the Porsche 911 range with a separately opening tailgate.

More Sophisticated and Comfortable
Beneath the glass top, the Porsche 911 Targa 4 and Targa 4S boast luxuriously appointed passenger cabins. Like all Porsches, the cars offer their occupants the protection of six airbags: dual frontal-impact airbags as well as two seat-mounted thorax-protecting side-impact airbags and two head-protecting side-impact curtain door-mounted airbags.

Interior refinements include a revamped center console highlighted by a new Porsche Communication Management system-PCM 3.0-and the availability of ventilated front seats.
The optional navigation module now has a 40 GB hard drive. Other available features with the newest PCM include XM satellite radio with XM NavTraffic capability, Bluetooth connectivity, an iPod port, a USB port and an auxiliary jack.

Interior comfort may be further enhanced thanks to optional seat ventilating fans, available in conjunction with heated seats. These circulate air through the seatback and cushion upholstery to expedite cooling, heating and/or drying the driver and passenger.

Porsche Boxster, 2009

Porsche Boxster, 2009


 

In 1948, the 356 was the first sports car to bear the Porsche name, and in July that year the lightweight mid-engined roadster achieved its first motorsport victory. In 1953, the Porsche 550 Spyder was launched. This agile, lightweight race car was powered by a high performance 'boxer' engine which took it to countless international victories.

Porsche presented the second generation of the mid-engined Porsche Boxster roadster at the 2008 Los Angeles Motor Show. The highlight of the new generation is the new flat-six 'boxer' engines, developed with 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 Porsche Boxster and Boxster S.

Displacing 2.9-litres, the engine of the Porsche Boxster develops 255 bhp (188 kW) in the Boxster, an increase of 10 horsepower over the prior 2.7-litre model.

The 3.4-litre power unit in the Porsche Boxster S now features Direct Fuel Injection, and delivers 310 bhp (228 kW), up by 15 bhp.

Direct Fuel Injection standard on 3.4-litre S engine
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 engines respond 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.

Design emphasises performance
The seamless blend of function and design has always been the Porsche philosophy. The result is a design consistency which is recognisable from every angle. A design which is both powerful and refined, and whose lines emphasise its sports performance.

The evolutionary styling of the next generation Porsche Boxster embodies these principles. The latest models are clearly distinguishable from outside through their newly-designed nose and tail. The new halogen headlights with their integrated direction indicators are reminiscent of the lights on the Carrera GT, while at the rear, new LED lights taper to the outside and are integrated elegantly in to the restyled bodywork.

PDK: shifting gears more quickly, reducing fuel consumption
The new Porsche Boxster models are 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 Porsche Boxster accelerates from 0-62mph (100 km/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.

Porsche Doppelkupplungsgetriebe (PDK) - in detail
The next generation Porsche Boxster and Boxster S are available for the first time with the new Porsche Doppelkupplungsgetriebe (PDK), literally Porsche double-clutch gearbox. Offering no less than seven forward gears, the new gearbox combines the driving comfort of a torque converter-equipped automatic transmission with the dynamic manual gearshift functionality of a sequential racing gearbox. PDK also boasts an entirely automatic gearshift function, and replaces the Porsche Tiptronic S automatic transmission previously offered. Through its optimised and adaptive gearshift programmes, PDK further improves the acceleration of the Porsche Boxster models and reduces fuel consumption to an even lower level.

In principle, the PDK consists of a conventional manual gearbox and a hydraulic control system divided into two separate transmission units. Two wet clutches in radial arrangement, controlled hydraulically, and using oil for both cooling and lubrication, form the heart of the transmission. One clutch is for the first transmission unit with the uneven gear ratios (1,3,5,7) and reverse, and the other clutch is for the second transmission unit with the even gears (2,4,6). Via a number of pressure valves, the hydraulic control unit masterminds both the wet clutches and the shift cylinders activating the transmission ratio required.

The gearshift perceived by the driver comes not from the gears actually changing, but from the change of positive clutch engagement. In this case, the clutch on one transmission opens or disengages while the clutch on the other transmission closes or engages in a simultaneous process. The big advantage is an even faster gearshift than with a conventional manual gearbox or torque converter automatic transmission. The gears are already 'in mesh' when shifting and the power of the engine need not be interrupted in the process.

Porsche Panamera

Porsche Panamera 2010

The Porsche Panamera designers have succeeded in positioning it as a brand-new and truly different model while retaining the looks of a typical Porsche. Through its proportions, the Porsche Panamera stands out in its market segment: measuring 76 inches wide and 55.8 inches in height, it is wider and lower than comparable four-door models. The unmistakable GT silhouette is created by the car's overall length of 195.7 inches and short, sporting overhangs. In its styling and details, the Porsche Panamera follows the design philosophy refined over decades on the 911 and successfully implemented on the Boxster, Cayman and Cayenne.

Pure Porsche DNA and comfort for four
Through its design language, the Porsche Panamera establishes a new segment. The symbiosis of sports car DNA derived from the looks of a coupe, the unique interpretation of the classical saloon body and the benefits of a variable space concept give the new Porsche a truly unmistakable appearance. The Porsche Panamera comes with strongly contoured air intakes instead of a conventional radiator grille. Striking wheel arches and the long and sleek engine compartment - with the distinctly contoured wings flanking the flat front lid - create the typical 911 "landscape" Porsche customers have appreciated for over 45 years. V-shaped seams along the hood and a rear window that tapers like an arrow to the rear also are characteristic of a sports car. Muscular shoulders over the rear wheels, the sweep of the coupe-like roofline and visible tailpipes again bear the thoroughbred Porsche DNA.

The an elegant roof arch extends over the generous interior. Thanks to the unique and sporting architecture of the interior, the car's occupants are able to experience a cockpit-like atmosphere from all four seats. All occupants enjoy supreme comfort in both the front seats and the two contoured rear seats. The luggage compartment easily takes all passengers' luggage; the Panamera's variable space concept with folding rear backrests enables driver and passengers to adjust the luggage space to individual requirements. Finally, the coupe tailgate in the sporting rear end combines everyday usability with stylish elegance.

The Porsche Panamera built in Leipzig; powerful engines hail from Zuffenhausen.
Porsche has developed powerful and up-to-date engines for the Panamera, reflecting the qualities typical of the brand; the V-engines come with six and eight cylinders and output ranges from 300 to 500 horsepower. Some engines use turbocharging technology and Direct Fuel Injection, making them both fuel-efficient and very powerful. Power flows to the wheels through either a manual six-speed gearbox or Porsche's seven-speed PDK Doppelkupplungsgetriebe, or Double-Clutch Gearbox.

TechArt Porsche Boxster, 2005

TechArt Porsche Boxster, 2005




Athletic Beauty: TechArt Widebody based on the Porsche Boxster (987)

The Athletic beauty: The TechArt Widebody based on the Porsche Boxster of the 987 model range doesn't only offer spectacular design but also extra driving fun and agility. After the huge success of the Widebody concept for the first Boxster generation, TechArt Automobildesign ( www.techart.de ) developed a wide body version for the current version of the roadster.

With the add-on fender flarings on front and rear axle the TechArt Widebody is eight centimeters wider than the standard car. The front extensions don't only provide extra room inside the wheel houses but also improve the deventilation of the heated up air with their integrated wheel-house ventilation. The rear flarings are equipped with largely dimensioned air ducts to bring fresh air to the centrally placed engine.

Apart from spectacular, sporty design the TechArt designers of course paid attention to optimal aerodynamic efficiency. The TechArt front spoiler bumper reduces the lift at the front axle and improves the cooling of the front brakes with large air ducts. The TechArt rear apron with integrated diffuser rounds out the conversion.

Extremely broad wheels and tires make the TechArt Widebody concept for the Boxster complete: Specially for this wide body version they developed custom-made versions of the one-piece TechArt Formula five spoke wheel. The front axle is equipped with wheels in size 8.5Jx20, the rear axle is equipped with 11Jx20 wheels.

TechArt Automobildesign recommends ContiSportContact 2 high performance tires in sizes 235/30 ZR 20 front and 305/25 ZR 20 rear for the Widebody based on the Porsche Boxster. The height-adjustable TechArt sport suspension is specially set-up for these ultra-wide wheels and tires and the wider track of the car. The coil-over suspension doesn't only provide an individual damping of the roadster but also lowers the two-seater car by some 25 millimeters. Boxster models with PASM system can be updated with the sporty set up TechArt coil over sport suspension.

TechArt also offers engine tuning for the Widebody. The two watercooled six-cylinder boxer engines can be upgraded with the TechArt power kits. They each consist of a sport air filter and newly programmed engine electronics. The result: 15 hp / 11 kW extra power and optimized road performance.


Being world-wide renowned specialists for exclusive interiors, TechArt provides individual full leather trims in all colors and designs. The range reaches from completing the ex-works leather trims up to a completely redesigned cockpit with special sports seats and ergonomically shaped airbag sports steering wheel.
