2012 Porsche 928 (GT Coupe) Preview
As mules currently in testing suggest, Porsche has in development a third front-engined car. Coming after the successful Cayenne SUV, and the future Panamera saloon (expected in 2009), the third model will be a large four-seat coupe.
Logically, this successor of the 928 will be technically based on the Panamera. Featuring the same drive-train layout, the two cars will share more than 60% of their components, including engines, transmission and suspension. It is even said that the decision of building a new FR coupe was taken in order to render more profitable the new Panamera technical platform. The cost-reduction fight doesn’t forget anyone, and few are the cars these days, that don’t share technical components with others.
Comparing to the Panamera, the 928 GT Coupe will have a shorter wheelbase and will loose some weights. This will make it sportier than the sedan.
The 928 GT Coupe will be powered by the same engines used in the Panamera. The normally aspirated and turbocharged V8 (used in the Cayenne) will be the first options. The V8 will rank between 4 and 6 liters of displacement and producing power values amid 300 and 650 bhp. Also the GT Coupe will use the 5.7 litre V10 engine producing 605 hp used in the Carrera GT.
The Direct Fuel Injection (DFI) technology first used in the Cayenne will be also used in the GT Coupe. This technology lowers the fuel consumption of individual models by over eight percent (NEDC). In real driving conditions, savings of up to 15 percent are possible.
2008 Porsche 911 Turbo Cabriolet
As with the 911 Turbo Coupé, the Cabriolet will also be powered by a 3.6 liter six-cylinder ‘boxer’ engine with biturbo turbocharging and Variable Turbine Geometry (VTG). The powerplant already generates 480 hp (353 kW) and 620 Nm of torque at 1950 rpm. With the new, optional “Sport Chrono Turbo Package”, which includes an overboost function, up to 680 Nm is even intermittently possible.
The manual transmission version can accelerate from 0 to 100 km/h in just four seconds. With Tiptronic S the time can be cut to 3.8 seconds. Both versions can reach speeds of up to 310 km/h. Fuel consumption for the 911 Turbo Cabriolet is 12.9 liters per 100 kilometers – an exemplary value in the competitive environment.
In spite of the convertible-specific reinforcement of the chassis and automatic and the extendable rollover protection behind the rear seats, the open version of the 911 Turbo only weighs 70 kilos more than the Coupé. The light, three-layer soft top, which can completely automatically be opened or closed in roughly 20 seconds, enables a low balance point.
2007 Porsche Cayenne S Transsyberia
Compared with the “regular” version of the Cayenne S, the Porsche Cayenne S Transsyberia as a special rally version has been modified on a number of points serving first and foremost to enhance safety and the car’s racing performance.
Production Engine, Shorter Transmission Ratio
The power unit of the Porsche Cayenne S Transsyberia has been carried over from the regular road version of the Cayenne S with hardly any changes: Output of this 4.8-litre naturalaspiration V8 with direct gasoline injection remains 385 bhp (283 kW) at 6200 rpm. Maximum torque of 500 Newton-metres or 369 lb-ft, in turn, comes at just 3500 rpm.VarioCam Plus valve management ensures a smooth and consistent surge of power throughout the entire speed range, with engine management varying valve lift on the intake side between 3.6 and 10 millimetres as a function of engine speed. And with the intake manifold also being variable in length, the engine provides muscular torque right from the start even at low engine speeds. Despite the increase in power over the previous engine, the new 4.8- litre reduces fuel consumption by approximately 15 per cent, giving the Cayenne S a significantly longer cruising range than before – obviously a big advantage particularly in a long-distance rally.
2007 Porsche Cayenne
With a striking new face that features a dramatic new headlight design and with a wide and muscular body accented by broad wheel arches, the 2008 Porsche Cayenne’s newly sculpted shape provides vivid visual testimony to the vehicle’s enhanced technical features. bThe 2008 model year marks the launch of the second generation of the Porsche SUV, and the new Cayennes back up their aggressive new design with larger and more powerful – but also more fuelefficient – engines.
As you would expect from Porsche, the new Cayenne not only looks more powerful, it is, with engines offering as much as 500 horsepower and new dynamic technologies that allow the Porsche of SUVs to perform more like a more nimble vehicle, yet still be capable of towing a trailer or challenging unpaved terrain and inclement weather.
Indeed, all three 2008 Porsche Cayenne models feature engines that for the first time boast direct fuel injection, a technology that enhances fuel efficiency as well as power production. For the 2008 Porsche Cayenne Turbo, that means a twin-turbocharged 4.8-liter V8 that pumps out an astounding 500 horsepower and 516 pound-feet of torque. Flowing through a six-speed Tiptronic S transmission, that power feeds all four wheels and propels the five-passenger sports machine from a standing start to 60 miles per hour (96 km/h) in just 4.9 seconds. Top speed on the test track has been recorded at 171 mph (275 km/h). And yet, the Cayenne Turbo qualifies as an LEVII (low-emission vehicle) and in preliminary fuel economy testing the Cayenne Turbo showed the benefits of the direct fuel injection technology with an improvement up to 11 percent in highway driving. The estimated EPA fuel economy values are 13 mpg for city driving and 20 mpg on the highway.
2009 Porsche 911 Carrera S
Comparing to the current Carrera, the new model will feature an updated front fascia and LED headlamps (also used in the 2008 Porsche Boxster). The air intakes are also enlarged and they integrate the turn signals (thankfully in a horizontal arrangement, as opposed to the fang-like design on the 2008 Cayenne).
From the chin spoiler a subtle lower lip extends and continues all the way down to the body sides and into the rear bumper. Said bumper has been revised to accommodate wider-set tailpipes and, unfortunately, droopy Cayenne-style LED tail lamps. Also it is expected that the interior to be updated to go with the new exterior.
2008 Porsche 911 Turbo Convertible (997)
The new front end will have the same look as the Turbo Coupe, but like any other future Porsche model, the 997 Turbo Convertible will feature distinctive large front Cayenne-style LED headlamps, deep airdam and intake and side air-scoops.
Already unveiled in the Porsche Cayenne, 997 Turbo Convertible will also use the new Direct Fuel Injection (DFI) technology, which is supposed to lower the fuel consumption of individual models by over eight percent (NEDC). In real driving conditions, savings of up to 15 percent are possible. The same DFI technology will be used in all the 911 future models.
The 911 Turbo Convertible will make the 0 to 60 mph sprint in 3.5 seconds and will have a top speed of 191 mph.
The 997 Turbo Convertible will feature new and larger wheels combined with 19-inch tires, weight reduction on the various components as well as enhanced torsion and flexural stiffness.
