Panamera S

Making its official debut at the 2011 Geneva Auto Show, Porsche’s Panamera S Hybrid brings together a winning combination of performance, luxury, and impressive fuel efficiency. As the second vehicle in Porsche’s line of production hybrid models, the Panamera S Hybrid is the most fuel efficient Porsche of all time and leads the luxury hybrid class.

The same gasoline engine and electric motor combination that has been a proven performer in the Cayenne S Hybrid drives the Panamera S Hybrid. The 3.0-litre supercharged V6 engine delivers 333-horsepower and is supported by a 47-horsepower electric motor. Together, with just 20 horsepower less than the Panamera S, the Hybrid boasts 380-horsepower with a fuel consumption of only 7.1 litres per 100 kilometres based on the New European Driving Cycle (NEDC); the NEDC is supposed to represent the typical usage of a car in Europe and is used, among other things, to assess the emission levels of car engines. With the use of optional low-rolling-resistance tires developed especially for the Panamera, fuel economy improves to only 6.8 litres per 100 kilometres. Official EPA fuel economy estimates for North America will be available closer to the vehicle’s on-sale date.
As the Panamera S Hybrid sets new standards in hybrid efficiencies, it also pushes the envelope when it comes to performance. It accelerates from 0 to 60 mph in just 5.7 seconds, topping out at a speed of 167 mph (270 km/h.) Its range in purely electric mode is approximately one mile, with electric-only acceleration possible up to just over 50 mph (85 km/h.)

The parallel full hybrid system is significant due to the fact that the compact electric motor is integrated directly into the transmission. The electric motor, which also serves as the vehicle’s generator and starter, combines with the decoupling clutch to form the compact hybrid module that sits between the combustion engine and the transmission.

The electric motor is connected to the system’s high-voltage nickel-hydride (NiMH) battery that stores electrical energy recovered from braking and driving. A special battery management system with a separate cooling system keeps the temperature constant and ensures optimum efficiency.

The entire system is regulated by the electronic engine management system. It decouples the combustion engine or switches it on, performing both these actions quickly and smoothly. And due to the rapid action separating coupling and the equally fast responding combustion engine, these processes are seamless and harmonious.

As expected, the Panamera S Hybrid comes very well equipped. Adaptive Air Suspension with Porsche Active Suspension Management (PASM) adaptive shock absorber system, Servotronic® variable-assist power steering, and a rear window wiper come standard. The car also features the Cayanne S Hybrid’s special display which provides the driver with relevant information regarding the status of the vehicle’s hybrid system. Other standard features include Porsche Communication Management (PCM) with navigation and a universal audio interface that connects to an external audio source, such as an iPod or USB stick, to the PCM.

The Panamera S Hybrid will go on sale later in 2011 at a base suggested retail price of $95,000.
