Cayenne S Hybrid Details Released
February 20, 2009 by admin
More information has just been released by Porsche on the new Cayenne S Hybrid that will finally launch in 2010. The company has changed up its powertrain plans since originally announcing the hybrid.
Instead of the older 3.6L normally aspirated V6, it will now use the new supercharged and direct injected 3.0L found in the new Audi S4 and A6. The 333 hp V6 is paired up with a 52 hp electric motor sandwiched between the engine and 8-speed automatic transmission. The combination of the engine, motor and nickel metal hydride battery can propel the Cayenne to 62 mph in 6.8 seconds.
The 154 lb battery pack occupies the spare tire well. As a strong hybrid system, the Cayenne can operate in electric, internal combustion or blended modes. The motor and battery have enough power output to allow the SUV to run on electricity at speeds up to 82 mph when cruising on level ground. The hybrid motor also replaces the conventional alternator further reducing parasitic losses in the system.
Porsche expects the hybrid Cayenne to top 26 mpg (U.S.) on the NEDC combined drive cycle, slightly better than the 25.3 achieved by the new diesel.
