Porsche's heftiest model benefits from hybrid power

DailyTech first talked about the Cayenne Hybrid way back in 2007. At the time, the vehicle was to be powered a 280hp 3.6-liter V6 engine paired with a 50hp electric motor. The powertrain was to be shared with the Cayenne's cousin, the Volkswagen Touareg.

A lot of time has passed since our original July 2007 story and quite a bit has changed with the Cayenne and the powertrain which will be used in the production version of the vehicle. The production hybrid will now be based on the second generation Cayenne which brings a wealth of advancements to the table. For starters, the vehicle now has a 1.57" longer wheelbase to add more rear passenger legroom. Also, the second generation Cayenne itself is now 440 lbs lighter than the first generation model thanks to the use of aluminum for the hood, doors, front bumper, and various drivetrain/suspension components. Less weight is always a good start when trying to extract better fuel economy from a vehicle.

The Cayenne Hybrid is able to save additional weight over its siblings with a Torsen 4WD system nabbed from the Audi Q7 crossover. The Torsen system is lighter than the multi-plate clutch 4WD system used on the standard Cayenne models.

The Cayenne Hybrid ditches the 280hp 3.6-liter V6 in favor of a smaller, supercharged 3.0-liter TSFI V6 engine which also sees duty in the Audi S4. The engine produces a healthy 325 hp and 324 lb-ft of torque. The electric motor adds in another 50hp and 184 lb-ft of torque according to AutoCar (for comparison, the 4.8-liter V8 used in the Cayenne S develops 394hp). For those that would like the ability to cruise along in near silence, the Cayenne Hybrid can travel just over one mile on battery power alone at up to 31 mph.

The hybrid powertrain is said to be good enough to scoot the Cayenne Hybrid to 62 mph in 6.5 seconds and return 34.5 mpg on the European cycle.

Just Over A Mile...?

Is this a joke?

No, not at all. It as serious as this porsche is at being a super-duper, stealth assassin super weapon!

If you take a look at it for a moment, you will notice that it has a large storage area located in the rear of the vehicle. I gander you could fit about 5 Ninjas in there (six maybe if they are really flexible). With the super-duper 1 mile range of "stealth mode," you could inject a crack Ninja squad into just about anywhere!

The tinted windows in the back are meerly a ruse and a distraction too. Everyone knows Ninjas are invisible. Even IF there was no window-tint in the back, you could not see the ninjas until it was too late; late as in staring at them with your eyeballs after they flipped over you, cut your head off and impaled in on a pike and turned it to face them.

You get the idea though. That is is why the car is black. It is a secret Ninja death weapon. Do not question the author! ;)

File this under a big "Who gives a Sh--?"
Cayennes have always been the prefered ride of those who have a lot of disposable income, want a designer label and don't know what they're doingwhen it comes to cars.
Now they can get one with a battery

Let's see, one mile is good for ... hmm ...

sneak out or back to the driveway without waking the wife.

1.2 mile on battery does not represent a large reserve capacity.
Further reduce the engine size to take off 50HP. Add 50HP to the electric motor. Increase storage to handle 10miles on battery. Large downhill to recharge, assist long climbs and more ICE off time.


50?

What good exactly is the 50hp going to do to the Cayenne?
It should be more than travelling 1 mile at 31mph right?

Is it aiding acceleration? Is it acting also as a generator while braking?

What is it really doing to achieve the mind-blowing 34.5mpg?

it has to travel downhill to achieve that figure, with wind coming from the back, and some guy pushing it.

Um, the electric motor significantly assists in acceleration because of its 184 lb-ft of torque. 50hp is nothing, that just means when it's cruising, the electric motor can't assist much at all.

However, since most fuel is used during acceleration, having lots of torque (what electric motors are good at) helps fuel economy by a lot.


Battery...

A battery that allows for a full mile...that's really great...or not...

That will get you to the bank. You will need to walk back.


Unit conversion

34.5mpg (Imp) equates to about 28.7mpg for the rest of us.

Not bad for a car of this size, but not as terrific as the article would spin either.

Nothing that either US VW TDI Toureg (V10 or V6) wasn't already doing in real world.

I just wish for a time travel machine to put myself 5-10 years in the future so I can start laughing now. Just like we have chuckling about E85 now versus 4 years ago, these hybrid/petrol combinations are amateur efforts. Either diesel/hybrid or hcci/hybrid or just plain diesel.

Still on the lookout for my A6 TDI US spec I saw about a month ago.

This should be called The "Tiger". Able to get away from the wife silently & just in case has fire hydrant avoidance & window & door resistance to golf club strikes.

Appropriate quote for a driver of one of these:

what a styling disaster the Cayenne is! Has to be one of the ugliest cars on the road.
