The Porsche Cayenne S E-Hybrid (2014-2018) and its predecessor, the Porsche Cayenne S Hybrid (2010-2014), share similarities in being hybrid versions of the Cayenne SUV, but there are notable differences between the two models:

Powertrain Technology:

• Cayenne S Hybrid (2010-2014): The earlier Cayenne S Hybrid utilized a parallel full-hybrid system. It combined a 3.0-liter supercharged V6 engine with an electric motor for a total system output of 380 horsepower. This hybrid system did not offer a plug-in capability, meaning it could not be charged externally for all-electric driving.
• Cayenne S E-Hybrid (2014-2018): The Cayenne S E-Hybrid introduced a plug-in hybrid system, which was a significant advancement over its predecessor. It combined a 3.0-liter supercharged V6 engine with an electric motor and a lithium-ion battery pack. This allowed for an electric-only range of approximately 14 to 22 miles, making it possible for short trips on electric power alone.

Performance and Efficiency:

• Cayenne S Hybrid (2010-2014): While it provided some hybrid efficiency benefits, the Cayenne S Hybrid’s performance and fuel efficiency improvements were relatively modest compared to the Cayenne S E-Hybrid. It had a less advanced hybrid system and couldn’t travel as far on electric power alone. It had a total system output of approximately 380 horsepower and 427 lb-ft of torque. It could accelerate from 0 to 60 mph in approximately 6.1 seconds.
• Cayenne S E-Hybrid (2014-2018): The Cayenne S E-Hybrid offered improved performance and efficiency due to its plug-in hybrid system. It had better acceleration and could achieve greater fuel economy when used as a hybrid or in all-electric mode. It had a total system output of around 416 horsepower and 435 lb-ft of torque. It could accelerate from 0 to 60 mph in just over 5 seconds. Both had a top speed near 150mph.
