Even More Efficient, More Sporting and for the First
Time with Hybrid Drive
World
Debut in Geneva: The New Porsche Cayenne
Dr. Ing. h.c. F.
Porsche AG, Stuttgart, is presenting the brand-new
generation of the Cayenne Sports Utility at the Geneva Motor Show in
early March.
The absolute highlight of this new generation is the world debut of the
Cayenne S Hybrid with its technically highly sophisticated parallel
full hybrid drive and fuel consumption in the New European Driving
Cycle of just 8.2 litres/100 kilometres (equal to 34.4 mpg imp), which
means CO2 emissions of just 193 g/km. The Cayenne S Hybrid therefore
combines the performance of an eight-cylinder with the economy of a
six-cylinder running on much less fuel.
Led by the Cayenne S Hybrid, all models in the new generation are
trendsetters in efficiency and performance in their respective
segments. Compared with the former models, fuel consumption is down by
up to 23 per cent, since the new Cayenne, like every Porsche, has been
developed according to the principle of “Porsche Intelligent
Performance”: more power on less fuel, greater efficiency and lower CO2
emissions.
These objectives result, not least, from the introduction of the new
Tiptronic S eight-speed automatic transmission with Auto Start Stop and
a wide spread of gear ratios, thermal management on the engine and
transmission cooling circuit, on-board network recuperation, variable
engine cut-off and intelligent lightweight construction.
Thanks to its special combination of materials for optimum weight as
well as changes in the overall concept of the vehicle such as the
Cayenne’s new active and extra-light all-wheel drive, weight is down
for example on the Cayenne S by 180 kilos or 400 lb – despite the
improvement of product substance and an even higher standard of safety.
This clearly has very positive effects not just on fuel consumption and
CO2 emissions, but also on performance, agility and handling.
Benefiting from these features and new technologies, the new Cayenne
offers even more driving pleasure both onroad and offroad, combined
with even greater everyday driving qualities, enhanced comfort and
supreme elegance. The completely new, sporting and elegant design of
the new model integrates the 2010 Cayenne even more closely into the
overall range of Porsche cars. The sports car-like character of the
Cayenne comes out even more from all angles, just as the highlights in
the shape and design of the car so typical of Porsche are also clearer
than ever before.
Extra space inside and greater variability is ensured by the wheelbase
now 40 mm or almost 1.6” longer. In all, the new Cayenne is 48 mm or
1.9” longer than its predecessor. But despite its larger exterior
dimensions, the new generation of the Cayenne is nevertheless far more
compact and dynamic. The most significant eye-catcher within the
brand-new, high-quality interior is the centre console rising up to the
front with its upright selector or gearshift lever, giving the interior
the typical character of a cockpit upfront. The rear-seat bench moves
fore-and-aft by 160 millimetres or 6.3”, with the backrest angle
adjusting to three different settings.
Sales of the Cayenne in Europe are starting on 8 May, with Porsche
offering the right model from the start for every customer: The range
starts with the 3.6-litre V6 Cayenne. Despite the increase in engine
power to 300 bhp, fuel consumption in the NEDC driving cycle in
conjunction with optional eight-speed Tiptronic S transmission is down
from the former model by no less than 20 per cent to 9.9 ltr/100 km,
equal to 28.5 mpg imp.
The Cayenne Diesel
with its 240 bhp (176 kW), 550 Newton-metre (405
lb-ft) three-litre V6 likewise reduces fuel consumption by 20 per cent,
down from 9.3 to 7.4 ltr/100 km (equal to 30.4 mpg imp now improving to
38.2 mpg imp).
Fuel consumption is also down significantly on the high-torque Cayenne
S with its 4.8-litre V8 power unit, in this case by 23 per cent to 10.5
litres/100 kilometres (equal to 26.9 mpg imp). At the same time the new
engine delivers 400 bhp maximum output instead of the former 385 bhp,
offering significantly better performance, just like all models in the
new generation of the Cayenne.
This also applies to the Cayenne Turbo, with its 500 bhp (368 kW)
4.8-litre V8 biturbo consuming just 11.5 ltr/100 km (equal to 24.6 mpg
imp) in the New European Driving Cycle, again 23 per cent less than its
predecessor (14.9 ltr/100 km or 19.0 mpg imp).
Together with the Cayenne S Hybrid, no less than three of the five
versions of the Cayenne thus consume less than ten litres of fuel per
100 km in the New European Driving Cycle, with two models emitting less
than 200 grams of CO2 per kilometre. At 193 g/km, the Cayenne S Hybrid
is not only the cleanest version of the Cayenne with the lowest level
of emissions, but also the cleanest Porsche throughout the Company’s
entire portfolio.
In the intelligent interaction of the three-litre supercharged V6 and
the electric motor, the Cayenne S Hybrid focuses on maximum efficiency
from the overall system. Depending on driving conditions, the vehicle
reaches this target with either only one drive unit operating by itself
or with both drive units working together. In this context the 34 kW
(47 hp) electric motor is of course the ideal partner for the 333 hp
compressor engine with its high torque at low speeds. Together, the two
drive units deliver maximum system output of 380 bhp and peak torque of
580 Nm/427 lb-ft at just 1,000 rpm, with the same kind of performance
as the Cayenne S with its V8 power unit.
The two drive units are connected to one another by a separator clutch
masterminded by the Hybrid Manager. Indeed, this separator clutch is
essential to run the Cayenne S Hybrid either on its electric motor or
combustion engine alone, or with both drive units operating together.
Given a reserved, moderate style of motoring, for example in a
residential area, this allows the driver to cover short distances on
electric power alone and therefore absolutely free of emissions and
with hardly any noise, driving at a speed of up to 60 km/h or almost 40
mph.
To ensure fast acceleration when setting off, the electric motor may
however serve to provide additional thrust through its boosting effect.
Intelligent management of the separator clutch makes the transition
among the hybrid-specific driving modes most inconspicuous, comfortable
and quick for the driver. At the same time the combustion engine may be
completely switched off at speeds of up to 156 km/h or 97 mph, being
fully disengaged from the drivetrain when no further power is required.
In this so-called sailing mode, cruising along without power, the drag
forces exerted by the combustion engine and their braking effect are
eliminated in the interest of lower drive resistance and fuel
consumption.
The prices of the new Cayenne models in Germany including national
specifications and 19 per cent value-added tax (Euro base prices
without national specifications and 19 per cent VAT in brackets) are as
follows:
Cayenne 55,431 Euro (46,400 Euro)
Cayenne Diesel 59,596 Euro (49,900 Euro)
Cayenne S 72,686 Euro (60,900 Euro)
Cayenne S Hybrid 78,636 Euro (65,900 Euro)
Cayenne Turbo 115,526 Euro (96,900 Euro).
