Stuttgart’s Porsche Panamera is entering the second production year so to further enhance the model, the automaker is now offering a series of new options that help improve fuel consumption.
These particular options are te new brake energy recuperation system that will come as standard on the Porsche Panamera, and the optional 19 inch all-season tires that enable the 4-door sports car to reduce fuel consumption by 0.9-litres per 100 Km. This means the top ranging Porsche Panamera that packs 500 HP will need 11.3-litres (25 mpg) to cover 100 Km, instead of 12.2-litres as before (23.2 mpg).
On the Porsche Panamera Turbo these two options help improve consumption by 0.7 litres and some of the new features that will now be offered to customers also include new body and interior leather colors, a heated 3-spoke steering wheel, 3D maps and others.
Porsche press release :
Stuttgart. The eight-cylinder Panamera models
are entering the next model year as of August 2010 with an even higher
standard of all-round efficiency and new options. Particularly the new
brake energy recuperation system featured as standard, together with
optional 19-inch all-season tyres offering reduced roll resistance, give
the Panamera Turbo a further improvement of fuel consumption by 0.9
litres/100 km. As a result, the 500-horsepower top model now consumes
just 11.3 litres instead of formerly 12.2 litres/100 km in the New
European Driving Cycle, equal to 25.0 mpg imp (formerly 23.2 mpg imp)
and a reduction of CO2 emissions by 21 grams per kilometre. The Panamera
S and Panamera 4S now making do with just 10.3 ltr/100 km and,
respectively, 10.6 ltr/100 km (equal to 27.4 and, respectively, 26.7 mpg
imp in the NEDC), are likewise up to half a litre more efficient per
100 kilometres (equal to minus 11 grams CO2/km).
This increase
in efficiency results primarily from brake energy recuperation, with the
battery being charged primarily during application of the brakes and,
respectively, in overrun. When accelerating, on the other hand, the
field current in the alternator is reduced, minimising the load acting
on the combustion engine since it is now required to deliver even less
energy for charging the battery, instead making this energy available
for even faster acceleration. In conjunction with further improvements,
this battery charging strategy on the Panamera Turbo saves no less than
0.7 litres on 100 kilometres, while newly developed, optional all-season
tyres measuring 19 inches in diameter likewise serve to reduce fuel
consumption by another 0.2 ltr/100 km on each model in the Panamera
range. Together with the enhanced tread of the tyres, a special rubber
compound serves to reduce roll resistance while at the same time
increasing the mileage covered by the tyres. The Auto Start Stop
function has also been optimised, now allowing the driver to set off
again even faster and more comfortably after coming to a halt.
Torque Vectoring Plus (PTV Plus) now available as an option together
with Porsche Dynamic Chassis Control (PDCC) and a fully controlled rear
axle differential lock enhances the driving qualities of the Panamera V8
models. PTV Plus optimises steering behaviour by intervening in the
brakes on the inner rear wheel in a bend and generating an additional
rotational force acting in the same direction as the steering wheel. The
result is even more direct and dynamic steering when entering a bend –
and at the same time PTV Plus, in conjunction with the rear axle
differential, improves traction on the rear wheels when accelerating out
of a bend on the road.
As a further highlight, Porsche is
extending the range of paintwork colours, leather options and special
equipment for the Panamera. As an example, the Gran Turismo is now also
available with auxiliary heating and a three-spoke sports steering wheel
with gearshift paddles on cars equipped with PDK
Porsche-Doppelkupplungsgetriebe. Three-dimensional presentation of maps
by the further improved, optional navigation system may now also be
combined with a satellite image for even more realistic presentation and
enhanced orientation. Even traffic lane information is provided in this
way for complex road junctions in Europe and the USA. And last but not
least, the speed limit indicator so far covering only the Autobahn,
motorway and interstate now also comprises – depending on the database
material – main roads and major routes leading out of town.
