Porsche Cayenne Hybrid on the streets by late 2010

As everyone knows, Porsche's planning a range of production Cayenne hybrids. Now it was confirmed by Porsche board member Wolfgang Dürheimer, who told the German daily Rheinische Post that the vehicle would be in dealerships and on the street by the second half of 2010 with a starting price around €90,000 ($124,500).

Specifics on the Hybrid models haven't been abundant, but Porsche did release several key details about the Cayenne S Hybrid earlier this year. The vehicle is targeting V8 performance with four-cylinder emissions and efficiency - exactly what you'd expect of a hybrid.

But it's not just about the fuel-saving aspects. Teaming an Audi 3.0L V6 DFI engine rated at 333hp and 324lb-ft of torque with a 52hp, 221lb-ft electric motor and a 38kW NiMH battery pack, the Cayenne Hybrid S is a perkier than the regular hybrid, or 6-cylinder SUV. Zero to 62mph (100km/h) ticks by in 6.8 seconds, despite the ULEV II emissions rating, cutting CO2 by 20% compared to the standard version.

Porsche also revealed the function of the hand-off between electric and combustion drive. Good for up to 1.2mi (1.9km) on electricity alone, once that reserve is exhausted, the computer fires up the engine, engages the clutch and transfers power all in just 380ms. And it does it "without the driver or passengers noticing what is happening" according to Porsche.

An eight-speed transmission ties the whole system together, offering long gears at the high end for more efficient cruising. The top-speed gear is actually sixth, so seventh and eighth are effectively overdrives. In top gear, the vehicle can maintain constant speeds up to 86mph (138km/h) on electricity alone.

The Cayenne Hybrid S drive system will also make its way to a Panamera hybrid, which could hit the streets as early as the third quarter of this year. Source URL: https://carrevieeeew.blogspot.com/search/label/Porsche%20Cayenne%20Hybrid

2009 Porsche Cayenne Hybrid

Porsche’s upcoming hybrid ute will deliver more than 400 pound-feet of torque.
Two years ago at the Frankfurt auto show, Porsche announced it had begun work on a hybrid Cayenne program, but the company has remained quiet since then, except to tell us it has remained partnered with VW on the SUV’s development. However, Porsche recently broke its silence and gave us a few more details about what we can expect from its new hybrid SUV, which is on track for a 2009 launch.
What we know is that a compact, 34-kW electric motor in the Cayenne hybrid will slot between its 3.6-liter V-6 and the six-speed automatic transmission, a series configuration that Porsche claims is more compatible with the Cayenne’s platform. The company also says the setup is more fuel efficient and flexible in terms of the hybrid system management, which Porsche claims will allow the vehicle’s performance to remain, well, Porsche-like. By adding electric power to the 290-hp, direct-injection V-6, maximum torque rises from 273 lb-ft to over 400 at 1800 rpm for the hybrid. That part sounds good, but all the hybrid components will add significant weight to the already bloated Cayenne, so we’ll have to wait to see what affect this has on not only acceleration but Porsche hallmarks such as handling and braking as well.

Porsche’s fuel-economy target for the Cayenne hybrid is 24 to 26 mpg—some 25 percent better than the current V-6 Cayenne’s mpg. Porsche did not make any mention of reduced emissions, but we expect at least commensurate improvements along those lines.
Other unique features of the Cayenne hybrid that have been designed to decrease fuel consumption include the vacuum pump for the brakes and the air conditioning, which will operate on electric power. Components such as the oil pump in the Cayenne’s automatic transmission, have also been replaced by electrically powered units. Further efficiencies were gained by the fitting of an electrohydraulic steering system—a move that may not be welcomed by purists.
Porsche also plans to introduce a hybrid version of its Panamera four-door sometime after its 2009 debut.

This is all great news, we suppose, but we’re still scratching our heads trying to figure out exactly what the point is of a hybrid Cayenne or Panamera. After all, few people buy luxury SUVs or four-door GTs because they’re “green.” Nor, for that matter, do they stay away from them because they’re not.
To the contrary, however, Porsche has claimed in the past that more and more rich people are interested in environmentally sound vehicles. But is the demand really that high? The only thing we can surmise is that Porsche is bending under major regulatory pressures, because considering what low volumes the Cayenne hybrid is expected to pull in, there can’t be much money in it, even at the prices we expect Porsche to charge for its mighty new green machines.
