2011 Porsche Cayenne S HybridEnlarge Photo
We’ve previously told you that the Cayenne, as well as the Panamera, will be receiving a plug-in hybrid option at some point. Now Motor Trend is reporting that the option will be introduced in calendar year 2014 along with the SUV’s mid-cycle update.
The Panamera is expected to soon follow with a plug-in hybrid option, though its system will be used to power only the rear wheels while the Cayenne will stick with all-wheel drive
Porsche will be calling its plug-in hybrid system an ‘e-hybrid,’ and a preview of the technology was recently showcased in the Panamera Sport Turismo concept at the 2012 Paris Auto Show. Porsche’s e-hybrid system is an advanced development of the parallel full hybrid the automaker already implements today in the Cayenne S Hybrid and Panamera S Hybrid models.
The e-hybrid’s electric motor currently produces about 95 horsepower, and is matched to a supercharged 3.0-liter V-6 engine producing 333 horsepower on its own. Working together, the two power sources can accelerate a vehicle the size of the Cayenne from 0-60 mph in around 6.0 seconds or less.

Using a mix of electric and gas driving, Porsche’s e-hybrid system could return a fuel economy as high as 67 mpg in either the Cayenne or Panamera.
It’s not clear how long charging of the battery will take, though Porsche is developing a fast-charger system for its upcoming 918 Spyder plug-in hybrid supercar, and a version could be offered to owners of its e-hybrid range.
