On the road: impeccable road manners
The
Citroën C6 boasts impeccable road manners thanks to its
original
combination of multi-link axles and a suspension system
featuring
electronically controlled springing and damping.
In this way, the
C6 is able to offer unrivalled standards of comfort,
particularly in
terms of suspension and damping, vibration, road noise,
and
steering.
Front and rear suspension
Double wishbone front suspension with a linked hub
carrier
The double wishbone and linked hub carrier system
separates vertical suspension travel and deflection.
As a result, the Citroën C6 steers a precise course in
all
circumstances, even on uneven, bumpy roads. This
virtually eliminates
steering vibrations while optimising cornering
precision.
Multi-link integral rear suspension
The
rear suspension features a longitudinal arm linked to
the hub carrier
to ensure longitudinal control and to minimise
vibrations.
The
suspension is assembled on a light alloy cross-member to
provide good
geometrical precision and rigorous dynamic control of
each wheel, for
optimum driving dynamics.
Suspension with electronically controlled springing
and damping: placing the emphasis on efficiency
The
C6's new hydro-pneumatic suspension brings major
improvements in
comfort and refinement compared with conventional coil
spring systems.
It is coupled with a damping control system that can be
modified
instantaneously to place the emphasis on comfort or
sport. Sixteen
different control laws are available.
This suspension maintains the vehicle at a constant
height, regardless
of the vehicle load and number of passengers. To
maintain vehicle
attitude, body height is monitored in real time by
height sensors on
each wheel, which supply data to the electronic control
module.
In specified conditions, this system can automatically
lower clearance
by 12 millimetres from 110 kph, thus optimising
road-holding at high
speed as well as fuel consumption.
When the road is highly uneven and low speed is
necessary, the
suspension control unit increases ground clearance by
around 12
millimetres above the normal position. The driver can
therefore
continue safely over difficult ground, without damaging
the car.
This system ensures optimised driving pleasure and truly
exceptional comfort.
The suspension requires no maintenance for five years or
200,000 km. It
is designed to smooth away imperfections while ensuring
an excellent
ride, thus contributing to the well-being of all the
passengers. The
technologically advanced engines also contribute to this
impression
through their driveability.
Technologically advanced engines
The C6 is available with two V6 engines, each mated to
a 6-speed automatic gearbox.
Both engines offer a smooth build-up in power with
remarkably quiet running.
Petrol engine: 215 bhp DIN 3.0 V6
This engine features similar technology to the 3.0 V6
fitted on the C5,
with 2% more power (+ 3 kW) and torque (+ 5 Nm). It
delivers 155 kW EEC
(215 bhp DIN) at 6,000 rpm and 290 Nm of torque EEC at
3,752 rpm.
This engine is fitted with a new exhaust line and
dual-mode active
silencer, which improves both performance and engine
noise. By
redirecting the exhaust gases in the silencer, this
system improves
engine noise in normal conditions of use and improves
performance under
load.
In terms of environmental protection, the V6 engine
meets the Euro IV emission standard.
Diesel engine: 208 bhp DIN 2.7 V6 HDi
This new V6 diesel engine combines power and fuel
economy, and was
developed as part of the cooperation between the PSA
Group and Ford
Motor Company. Delivering a responsive performance from
the lowest
engine speeds, it develops 150 kW EEC (208 bhp DIN) at
4,000 rpm and
torque of 440 Nm EEC at 1,900 rpm. It combines smooth,
gradual power
with exceptional operating comfort.
Developed specially for luxury cars, this V6 engine uses
advanced
technologies to achieve high levels of performance and
operating
comfort.
Through its avant-garde design, this V6 engine satisfies
the Euro IV
emission standard and is equipped with a new-generation
particulate
filter, which only requires maintenance every 200,000
km.
Driving pleasure is enhanced not only by these two
engines
but also by a new 6-speed automatic gearbox as well as
variable
hydraulic power steering. Smooth gear changing ensures a
level of
driveability that is commensurate with the C6's
ambitions.
Citroën's uncompromising approach to safety, and
the prevention of accidents, is a key priority.
An advanced braking system
The
C6's high-performance braking system features four
ventilated discs,
measuring 330 mm in diameter at the front, and 302 mm at
the rear.
With the dedicated braking assistance and control
functions as well as
ESP, the driver is able to maintain control of the car
and keep it on
course even in the most difficult driving situations.
In terms of passive safety, the Citroën C6 features
efficient restraint
systems for all the occupants, together with a structure
designed to
resist the most violent impacts.
The body structure
The
C6 incorporates the passive safety features of the
Group’s platform 3
vehicles. Introduced with the C5, this platform base
sets the highest
standards of driver and passenger protection, as
illustrated by the
C5's exceptional results in EuroNCAP tests.
Nine airbags including one for the knees
The deployment pressure and volume of the two front
airbags depend on the severity of impact.
A knee airbag provides improved protection for the
driver's knees and
shins by limiting any impact with the steering column,
which retracts
by 80 mm.
Two side airbags integrated into the front seats protect
the chest and
abdomen of the driver and passengers in the event of a
side impact. The
C6 is also fitted with curtain airbags designed to
protect passengers
in the rear.
Active head restraints
Active
head restraints prevent whiplash injuries in the event
of a rear
impact. The force generated by the passengers' upper
bodies pressing
against the seat backs activates a lever system that
moves the head
restraints forward to cradle the occupant's head, and
thus avoid strain
on the neck.
Through its many qualities, the
Citroën C6 represents a new approach to luxury
vehicle design. Its
technical qualities clearly set it apart from the
competition. The
Marque's new flagship model, the Citroën C6, is a
car to truly stir the
emotions.
Innovative, cutting-edge
technologies make the C6 an exceptional car and
underline Citroën's
pioneering approach to design, safety and comfort.
