The German automaker has published full details with their upcoming Porsche Panamera S Hybrid, a market leading GT in terms of hybrid performance, which will be unveiled at the 2011 Geneva Motor Show.
The Porsche Panamera S Hybrid features the same system as the Cayenne S Hybrid, meaning a 3.0-litre supercharged V6 developing 333 HP (245 kW) backed by a 47 HP (34 kW) electric motor. If you do the math then you will understand that the combined output is 380 HP (279 kW), which is pretty impressive considering the Porsche Panamera S Hybrid promises to return 30.2 mpg (UK rating/combined cycle) and have CO2 emissions of 159 grams per Km. 
Accelerating from 0 to 62 mph (0 to 100 Km/h) in the Porsche Panamera S Hybrid will take 6.0 seconds, while top speed is 168 mph. 
The Porsche Panamera S Hybrid price for UK will start at 86,146 GBP will sales scheduled to begin in June 2011. For more detailed information check out the official press release below.
Porsche press release :

  • Market-leading hybrid performance – 2.4 hp per g/ CO2
  • Porsche Intelligent Performance delivers an efficient combination of power and economy
  • New 380 hp model charges from 0-62mph in 6.0 seconds and onto 168mph top speed
  • On sale June 2011, priced from £86,146

The Panamera S Hybrid marks the beginning of a new chapter of Porsche
Intelligent Performance, as well as continuing the success story of the
four door Gran Turismo. Without sacrificing its sporting driving
dynamics and elegant travel for four passengers, the new Panamera S
Hybrid combines a total power output of 380 hp (279 kW) with CO2 emissions of just 159 g/km, achieving a performance ratio of 2.39 hp per g/ CO2 that is unbeaten in the UK car market.
In addition to offering 0-62mph in 6.0 seconds and a top speed of 168
mph, the Panamera S Hybrid returns fuel economy of 30.4mpg Combined.
These statistics position the Panamera S Hybrid as offering impressive
levels of efficiency, achieved through a combination of clever
engineering solutions under the skin and the use of lower rolling
resistance tyres specially-developed by Michelin.
The range in purely electric mode is approximately 1.25 miles, with
driving in this mode possible up to 53 mph, depending on the road and
traffic conditions. The Porsche hybrid drive is also the only system in
the world able to exploit additional consumption reserves thanks to its
so-called ‘sailing’ function. During phases when no power is required
from the combustion engine, ‘sailing’ entails switching off the engine
and disengaging the drivetrain at speeds of up to 103 mph (Cayenne S
Hybrid 97 mph).
The Panamera S Hybrid is driven by the same engine combination that
has already proved itself in the Cayenne S Hybrid, a model which already
accounts for a fifth of Cayenne sales in the UK. The main propulsion is
provided by a supercharged three-litre V6 engine delivering 333 hp (245
kW) supported by a 47 hp (34 kW) electric motor. Both power units are
capable of powering the Panamera S Hybrid either alone or in
combination. The electric motor also operates as a generator and a
starter. Together with the separating clutch, it forms the compact
hybrid module located between the combustion engine and the
transmission.
The electric motor is connected to a nickel metal hydride (NiMh)
battery where the electrical energy recovered while braking and driving
is stored. Power transmission is handled by the familiar eight-speed
Tiptronic S, with a wide spread of ratios, as already fitted to the
Cayenne.
Every Panamera has a high level of standard specification that
includes leather interior, Porsche Active Suspension Management (PASM),
Bi-Xenon headlights, front and rear ParkAssist, tyre pressure
monitoring, automatic dimming rear view mirrors, Porsche Communication
Management with touch-screen satellite navigation and audio controls,
cruise control and a three year warranty. The Panamera S Hybrid also
features adaptive air suspension as standard, plus the innovative
display panel – already seen in the Cayenne Hybrid – that provides the
driver with all the relevant information about the vehicle’s specific
hybrid driving status.
With the introduction of the new hybrid, the Panamera range now
comprises six different models with a choice of two- and four-wheel
drive and four engines. This diversity echoes the evolving preferences
of Porsche customers, and which the sales success of the Panamera is
already confirming. Approximately 15 months after sales started, nearly
30,000 vehicles have been delivered worldwide, of which over 1,000 have
been in the UK.
The Panamera S Hybrid goes on sale in the UK in June 2011, priced from £86,146. The low emissions of 159 g/km CO2
is of particular relevance to fleet and company car buyers as it sits
under the Company Write Down Allowance threshold of 160g/km. This means
for a company purchase, the price can be offset against tax at the rate
of 20% per annum.
Fitted to every Panamera is a Porsche Vehicle Tracking System (VTS), a
sophisticated vehicle security package approved to Thatcham Category 5
standard, and customers will also be able to explore the potential of
their new car by participating in a complimentary course at the Porsche
Experience Centre, Silverstone.
