When the 2009 Porsche Cayenne hybrid hits the markets, the new gasoline-electric powered SUV will be capable of cruising at speeds up to 70mph on the electric motor alone. Once the gasoline engine helps the car 70mph, the SUV will stop using gas and the electric motor will be used for power.
Porsche is working with Bosch and Audi to produce the gasoline-electric V8 engine which will have a fuel economy of 26.8mpg.
“If Porsche was going to do a hybrid, it makes sense to do it from a performance standpoint,” said company spokesman Tony Fouladpour.
The Porsche Cayenne hybrid is expected to be in the price range of the base Cayenne, starting at $44,000.

But man...to be able to haul that weight at 70mph, the premium for those extra powerful electric motors and high-capacity batteries must be hella high. Guess they figured Porsche buyers can afford it after all.

this basically shows you how much power you really need to maintain a car at highway speed. A typical sedan needs 10-15hp. A battery + electric motor can supply that much power (Prius has a 28hp battery)

Because all that electricity power has to come from somewhere...namely more recharging from the gasoline engine.

during braking, the electric motor actually turns into a generator using the cars momentum to spin it, and it charges the battery during this time .....AKA regenerative braking.....the gas engine only helps recharge if the batteries are nearing depletion.

Press Release
ATLANTA, July 26, 2007 --- Porsche, a company renown for its high-performance sports cars and sport utility vehicles (SUV), this week in Stuttgart demonstrated to the media a Cayenne SUV hybrid prototype, providing a glimpse of what the company will offer to consumers by the end of the decade.
Porsche is targeting average fuel consumption figures of 9.8 liters/100 kilometers in the New European Driving Cycle and about 24 miles per gallon in the US FTP cycle for the Cayenne Hybrid, and future developments may allow Porsche engineers to push towards an average fuel consumption figure of 8.9 liters/kilometer (approximately 26 miles per gallon).
The Cayenne Hybrid will feature a full-hybrid design where the hybrid module (clutch and electric motor) is positioned between the combustion engine and the transmission rather than having the hybrid drivetrain branching output along various lines and in various directions via a planetary gearset. Porsche selected this design because the in-line configuration of the hybrid components are more compatible with the existing Cayenne platform, this system in testing is more fuel efficient, and because this configuration is a better fit for Porsche as it will provide improved acceleration and engine flexibility compared to a conventional Cayenne.
Coordinating the car's three main components - the combustion engine, the electric motor and the battery - is the Hybrid Manager, the heart of the Cayenne Hybrid. The Hybrid Manager, which oversees some 20,000 data parameters as compared to only 6,000 data parameters for a conventional engine, is one of the most powerful technologies found in any hybrid vehicle.
Other unique features of the Cayenne Hybrid designed to decrease fuel consumption include the power steering and vacuum pump for the brakes, as well as the air conditioning, which operate on electric power. Technical components, such as the oil pump in the Cayenne's automatic transmission, have been replaced by electrically powered units. The Cayenne Hybrid's electro-hydraulic steering - a first for a vehicle of its kind, will ensure the Cayenne Hybrid drives like a Porsche with predictable and safe handling characteristics and the agility that is expected of a Porsche SUV.
Porsche plans to introduce similar hybrid technology in a version of its Panamera four-door Gran Turismo. The Panamera will debut in 2009, with a hybrid to follow

OK so it can cruise at up to 70mph on electric motor only... great... for how long? Probably no more than 6 miles on a full charge... then it needs the gas motor back on full time until you hit the brakes again and develop a small charge to let you cruise on electric only again for what... 30 seconds?
Hybrid systems at highway speeds make very little sense to me unless they're able to have a usable range. I don't think much of anyone who's going to do 70mph on their commute will only do it for a few miles and then be done...

been wondering the same thing myself. Also, the gas engine is used to get you up to 70 right? Isn't most fuel used during acceleration?

This is another reason why Porsche is that brand (with Lexus lol). This is incredible. It also shows they know Hybrids are true tech that moves cars forward and are viable.
Porsche and Lexus have some of the brightest management on the planet. If they see it works, why doesn't everyone else?
