2011 Porsche Cayenne S Hybrid

(continued from above)

The Cayenne S Hybrid accelerates from 0 to 60 mph in just 6.1 seconds on its way to a top test track speed of 150 mph, yet it delivers an impressive estimated 21 mpg city/25 highway under current EPA regulations. Its base MSRP is $67,700 (excluding destination), and like all Cayenne models, it is not subject to a gas-guzzler tax.

Like most hybrids the Cayenne S Hybrid can drive for a time on electric power alone at speeds up to 37 mph. However, it delivers efficiencies at cruising speeds through its ability to 'sail' or coast with the combustion engine turned off. It can do this for up to one mile, and this not only saves fuel but also minimizes emissions.

In the Cayenne and Panamera model lines the 'S' designation indicates a V8 under the hood. But the 'S' in the Cayenne S Hybrid name is there for a different reason - to indentify the true performance character of this SUV's highly sophisticated parallel full hybrid system. With a combined power output of 380 horsepower from the supercharged V6 combustion engine and an electric motor, the Cayenne S Hybrid delivers performance nearly equal to the Cayenne S with its 400-horsepower V8 and fuel economy estimates that exceed those of the Cayenne with the V6 engine.

The all-new Porsche Cayenne has earned some significant awards since going on sale this summer. It is the 2011 Motor Trend Sport/Utility of the Year and also recently received the Auto Pacific Motorist Choice Award for Best Premium Active Lifestyle Vehicle.

Hybrid Manager Seamlessly Coordinates the Two Power Units

Through continuous interaction between the 3.0-liter supercharged V6 and electric motor, the Cayenne S Hybrid focuses on maximum efficiency. Depending on driving conditions, either drive unit can operate independently or together. The 47-horsepower electric motor is the ideal partner for the 333-horsepower engine, which produces high torque at low engine speeds.

Both power units are connected by a decoupling clutch, which ensures that the Cayenne S Hybrid may be driven either by the electric motor or the combustion engine alone, or by both drive units together. The Hybrid Manager constantly coordinates their complex interaction, and intelligent management of the clutch makes the transition among various driving modes seamless and comfortable.
