Porsche Panamera S Hybrid

Porsche has launched its second production hybrid model, the Porsche Panamera S Hybrid, adding another chapter to its Porsche Intelligent Performance development philosophy.

Without sacrificing sportiness or elegance, the Porsche Panamera S Hybrid produces 380 hp (279 kW) with CO2 emissions of just 159 g/km, achieving fuel consumption of only 6.8 L/100 km (34.6 mpg US) on the New European Driving Cycle (NEDC).

The Panamera S Hybrid accelerates from 0 to 62 mph (0-100km/h) in just 6 seconds and has a top track speed of 167 mph (270 km/h). Its range in purely electric mode is approximately 1.25 mile, with electric-only acceleration possible up to just over 50 mph (85 km/h), depending on the road and traffic conditions.

The Panamera S Hybrid is driven by the same parallel full hybrid system that has already proved itself in the Porsche Cayenne S Hybrid.

A 3.0-liter supercharged V6 engine delivering 333 horsepower is supported by a 47-horsepower (34 kW) electric motor. Depending on driving conditions, either drive unit can operate independently or together to drive the rear wheels. The electric motor, which also serves as the car's generator and starter, combines with the decoupling clutch to form the compact hybrid module located between the combustion engine and the transmission.

The electric motor is connected to a nickel metal hydride (NiMh) battery that stores electric energy recovered from braking and other driving situations. The transmission is the same eight-speed Tiptronic S fitted in the Cayenne models, with a wide range of gear ratios.

The Porsche parallel full hybrid system also reduces consumption at high speeds thanks to its 'sailing' or coasting mode. When the driver lifts off the accelerator at normal highway cruising speeds, the gasoline engine is completely switched off and disengaged from the drivetrain by a decoupling clutch. This eliminates the combustion engine's drag forces and braking effect in the interest of lower resistance, fuel consumption and emissions.

As soon as the driver presses the accelerator, to pass another vehicle for example, the gasoline engine smoothly starts within fractions of a second and engine rpms are increased to match the current vehicle speed. It does this seamlessly thanks to the Hybrid Manager, which also helps the Panamera S Hybrid accelerate dynamically in gears at higher speeds much like a conventional Panamera.

The Porsche Panamera S Hybrid has an even higher level of standard equipment than the V8 Panamera S. Adaptive Air Suspension with the Porsche Active Suspension Management (PASM) adaptive shock absorber system, Servotronic variable-assist power steering and a rear wiper have been added to the list of standard equipment. Other standard features include Porsche Communication Management (PCM) with navigation, the universal audio interface to connect an external audio source such as an iPod or a USB stick to the PCM system, and Bi-Xenon headlights. Inside, this new model also features an innovative display that provides the driver with relevant information about the status of the vehicle's hybrid drive systems.

With the launch of the new hybrid variant, the Panamera model line now consists of six different models. The new offering underlines the strategic importance of the Porsche Intelligent Performance philosophy, with a combination of sportiness and economy unique in its segment. As such, it builds on the Panamera sedan's considerable success, with over 30,000 vehicles delivered worldwide since it went on sale in late 2009.

The Panamera S Hybrid will go on sale in the United States later in 2011 at a base suggested retail price of $95,000 (excluding destination). In European market, the Panamera S Hybrid goes on sale in June 2011, priced from £86,146 (€102,714).
