Porsche and a 4000 rpm redline? Never.
I am willing to be you that a large number of Porsche owners are older senile men who just want s sports (or what they perceive to be a luxury) car and don't drive it in a sporty fashion at all.
Plus, I am sure there prospective buyers out there that would like a more fuel efficient Cayenne because they like the design, handling etc. and would welcome a diesel. All that matters is that the diesel engine delivers good fuel economy and has a sporty character. And diesel engines, despite most of them only revving up to 4,500 RPM can display a sporty character.

Hybrid SUVs of Porsche and VOLKSWAGEN: Economical late fuzes - Spiegel online - message - car
Porsche is spoiling its image with that one.
The motor in itself is not at all brilliant. Compared to a 30d, it's slow as hell, and I know what i'm talking about as I drove both motors. No sporty character, at all.
And compared to 420cdi, 350cdi, 35d, this motor is just too slow.
The Cayenne is not the heaviest and weakest of all germans SUVS, is that what you consider a Porsche?
Okay, I screwed up, is what Porsche should say now.
No green image as no hybrid, no sport image as ridiculously slow for a Porsche, what is that thing for?
Isn't a hybrid a better solution in every possible aspect? It can be sporty if the petrol engine is sporty, it saves CO2 emissions, gives a green image, can be sold at insane prices...
No, there's nothing remotely Porsche in that...thing.
Is this Audis Q7 hybrid engine?
Or will this engine be appearing in the Q7 hybrid?
Porsche is bound to give Audi and Bentley access to it after the Panamera and Cayenne hybrids have been launched. Right now Porsche are using it as a competitive advantage, especially when the Panamera will be tapping in to the same market as the A8.
Porsche Releases More Cayenne Hybrid Details, Including 3.0T
Atlanta, GA -- Porsche AG, the Stuttgart, Germany-based high-performance car and SUV manufacturer, shared more information about its Cayenne S Hybrid, which will debut next year. Using a parallel full hybrid design with the electric motor between the combustion engine and the transmission, Porsche engineers have been able to drive at speeds up to 86 mph without at all using the combustion engine.
This engineering achievement allows the Cayenne S Hybrid to roll freely - or 'coast' -- at highway speeds without the combustion engine on, greatly minimizing engine emissions and fossil fuel consumption. This differs from current hybrid concepts that deliver benefits mainly in city traffic. Porsche, in cooperation with Volkswagen, opted for the parallel full hybrid design as it also significantly improves acceleration, a concept that matches the company's philosophy of offering outstanding performance and efficiency. It also fits in the current Cayenne design with minimal alterations and without affecting interior space or luggage capacity.
When it comes to market in 2010, the Cayenne S Hybrid is expected to emit some 20 percent less C02 than comparable combustion engine vehicles with similar power output. Covering a 0-to-100 km/h sprint in just 6.8 seconds, it earns its 'S' designation by delivering V8 performance and four-cylinder efficiency, all while complying with the Ultra Low Emission Vehicle II (ULEVII) emission standards.
The Cayenne S Hybrid uses a supercharged Audi 3.0-liter V6 engine with Direct Fuel Injection (DFI), 333 horsepower and 324 lb-ft of torque from 2,900 to 5,300 rpm. It is mated with 52-horsepower three-phase synchronous electric motor that produces up to 221 lb-ft of torque and also acts as an alternator, and the combined power units are joined to an eight-speed automatic transmission. Also on board is a 154-lb. no-maintenance 38 kW nickel metal hydride (NiMH) battery. Measuring 13.7" x 24.9" x 11.5", it fits in the spare tire well, thus not compromising luggage capacity.
The Hybrid Manager is the Cayenne S Hybrid's "Heart"
The heart of these technologies is the powerful Hybrid Manager, which requires some 20,000 data parameters to operate (compared to a conventional engine control unit that operates on less than one-third of the data). Since a parallel full hybrid operates in three classic hybrid modes - power generated by the combustion engine and electric motor, power generated by the combustion engine only, and power generated by the electric motor only - the Hybrid Manager's main function is to seamlessly coordinate these modes to deliver optimal performance and efficiency.
With a clutch being the key connection between the combustion engine and the electric motor, the Hybrid Manager has the tough job of providing smooth but quick switching among the three hybrid modes without delay or a noticeable transition felt by the driver and passengers. For example, the Cayenne S Hybrid can motor along solely on electric power for up to 1.2 miles with the combustion engine off, and the Hybrid Manager will fire up the engine as soon as the driver presses the accelerator, increase engine speed appropriately and engage the clutch to transfer power to the transmission without the driver or passengers noticing what is happening. And, it does this within just 300 milliseconds.
When driving with just the combustion engine, the Hybrid Manager also will ensure the engine is operating as efficiently as possible in reference to its load. It switches the electric motor to an alternator mode, so the fuel consumed by the combustion engine not only efficiently powers the Cayenne but also generates electricity that can be 'parked' in the NiMH battery. Finally, when the driver presses the brake pedal, the Hybrid Manager feeds as much energy as possible from the electric motor (again running as an alternator) to the battery.
The Cayenne S Hybrid also has electrically driven ancillary components such as the air conditioning compressor and the power steering pump.
Unlike conventional Cayenne SUVs, the Cayenne S Hybrid uses an eight-speed automatic unit. Porsche engineers added to the conventional transmission oil pump a new electrical drive pump to shift gears smoothly and efficiently also in electric mode. Top speed comes in sixth gear, and the two higher gears serve to further reduce engine speed to enhance fuel economy. Eighth gear, for example, enables the driver to 'coast' along without the combustion engine at speeds up to 86 mph.
Porsche expects the Cayenne S Hybrid to consume less than nine liters of fuel per 100 kilometers in the New European Driving Cycle. EPA fuel economy figures are not yet available.
A similar hybrid system will find its way into the new Porsche Panamera(R) four-door gran turismo sometime following Porsche's fourth model line debut in late summer 2009.

Impressive that the car can drive at speeds up to 68 miles per hour on electric power. Absolutely amazing ans I suspect this car to be a major success, though I'm surprised that Audi has given them access to the brand new super charged S4 engine. On the other hand I can't see how anyone would want to buy this next year when the new Cayenne is merely 12 months away.
So the VW acquisition already starts paying off for Porsche. They use the V6 TFSI as found in the S4 or A6. I'm wondering if the Cayenne S will also get this engine without hybrid...
Best regards, south
Good thought. In general it seems like turbo and SUV go better together than superchargers and SUVS. Maybe some petrol head here can comment on whether this engine has the same favourable low-end torque burst as a turbo charged engine. Porsche are certainly picking what ever they want out of Audi's kitchen cabinet. It would surprise me if VAG decide to drop a detuned Veyron engine under the bonnet of the new Arnage.
What i don't get is why they did the awful Cayenne diesel with this hybrid about to be released. Though more expensive, it's much better solution!
