At the side, a distinctive contour line begins at the headlights and runs round the
rear wings into the painted section of the new "ruby" red rear light clusters
and extends along the panel of the boot lid.
The boot lid is now convex in shape and offers more boot space.
On the estate, the bumper has been redesigned and the tailgate has a chromed lower
edge.
All 406 models are enhanced by new wheel trims or new alloy wheels.
Inside
The interior ambience has been improved by a new dashboard fitted with chrome-encircled
dials and a redesigned central façade containing a LCD screen and more practical radio
ventilation controls.
The new four-spoke steering wheel has a central pad, which now contains the horn
control. The centre console and the door casings have been redesigned to offer greater
comfort and ease of use and the seats have been reshaped and trimmed with new materials.
There are six specification levels - L, LX, GLX, GTX, Executive and V6.
Engines
A new generation of petrol engines and an extended diesel range
The new 406 sees the launch of a new generation of petrol engines called EW, the first
of which has a capacity of 1997 cm3, 16 valves and power of 99 kW (137bhp) at
6000 rpm. Thanks to its alloy crankcase, overall weight saving and to major reductions in
internal friction, the performance and consumption of a 406 saloon with manual
transmission have improved perceptibly.
The mixed cycle consumption has been reduced by 10% to 33.9mpg over the superseded XU10
J4R engine and performance has developed in absolute terms with a top speed of 129 mph and
0 to 62 mph in 10.8 seconds.
The driving performance, although more subjective, is significantly improved thanks to
the increase in torque at low engine speeds (190 Nm at 4100 rpm instead of 180 Nm at 4200
rpm in the XU10 J4R). The improvement in controls, in particular the hydraulic clutch and
the gear selection, means these are gentler and more precise.
Improved versions of the 1.8 litre (112bhp) and the V6 3.0 litre (194bhp) complete the
range of petrol engines available.
HDi (High Pressure, direct injection diesel)
In Turbo Diesel form, the first generation HDi DW10 ATED direct injection Common Rail
engine appeared on the 406 in the autumn and has returned on the new 406 with a new
feature designed to perfect the acoustic and vibratory comfort. It has a double flywheel
with damper which allows smooth running even at very low speeds (down to around 1000 rpm)
while retaining the progressive acceleration of the HDi engine.
This engine develops a maximum power of 80 kW (110bhp) at 4000 rpm and a maximum torque
of 250 Nm (26 mkg) at 1750 rpm. Note that the efficiency of this engine allows a
significant reduction in CO2 emissions to 150 g/km and in fuel consumption
(mixed cycle 51.3 mpg). It also develops high torque at low engine speeds and a reduced
sound level.
On the new 406, this engine is now joined by another HDi version with the same capacity
of 1997 cm3 but giving 66 kW (90bhp) at 4000 rpm. This engine is intended for
the base models of the 406 range while offering the full intelligence of the high pressure
common rail with in particular the reduced mean fuel consumption.
Without an intake air exchanger, it nonetheless develops a power of 66 kW (90 bhp) at
4000 rpm and in particular a torque of 205 Nm (21.4 mkg) at 1900 rpm. The torque figures
available at low speed improve the driving pleasure, and as a bonus this engine emits only
154 g/km CO2 compared with 181 g/km for its predecessor. The mixed cycle fuel
consumption amounts to 50.5mpg compared with 40.9mpg before.
This engine replaces the indirect injection XUD9 BTF diesel and means that the new 406
Turbo Diesel range is powered exclusively by high pressure direct injection HDi. Thanks to
these new engines, the 406 range benefits from significant technological advances offering
a reduction in consumption and emissions coupled with improved driving behaviour.
Transmission, suspension and wheels
The 406 range models are fitted with 5-speed manual gearboxes or 4-speed automatic
boxes with the electronic control system known as "auto-adaptive".
The suspension and wheels of the 406 have undergone little modification. The front is
fitted with pseudo-MacPherson strut suspension with decoupled anti-roll bars and the rear
has a multilink system for strict control of the wheel plane under any conditions, thanks
to the four arms per unit.
The damping is improved by the general use of pressurised dampers (3 bar) which offer
greater heat resistance, and models previously fitted with 14" wheels now have
15" wheels shod in 195/65 R15H tyres which offer a low rolling resistance. The 406
versions powered by the 6 cylinder ES9 J4 engine are fitted with 205/60 R15V tyres and the
coupé with the same engine has the Michelin MXM 215/55 R16W.
In general the weight savings achieved with the new engines (EW - DW) have allowed a
change to the various spring and damper rates for enhanced driving comfort without
affecting behaviour.
All 406s are fitted with ABS and electronic braking distribution as standard. This
system not only divides the braking force between the front and rear axles but during
braking on corners, divides the force between the two wheels on the rear axle to benefit
the outer wheel which carries the most load.
Throughout the 406 range, the rack steering is assisted by an integrated hydraulic ram.
On the base models, conventional constant flow power steering is used but the mid-range
variants have modulated assistance (variable flow as a function of engine speed) and the
top range models variable assistance as a function of the vehicle speed.
All 406s have a four-spoke steering wheel in a new design which is adjustable in height
over 35 mm and in depth over 27 mm. The horn is now controlled by pressing the padded
centre of the steering wheel in the same way as the 206.
The new 406 - even stronger and safer
Strength and safety are strong attractions for the customer, both for reassurance and
durability.
Already well armed by its structural design and high level of active safety, the new
406 offers new benefits intended to increase its strength and the protection of its
occupants.
The new generation engines (EW and DW) are firstly positioned further away from the cab
thanks to their straighter alignment, thus releasing more absorption space in case of
impact. In the same spirit, the structural developments are intended to improve behaviour
at the front foot well thanks to the redesigned inner wings and padding which is arranged
in the lower part of the dashboard and a retractable cushion between the dashboard and the
cross member.
Passive safety has also increased by the introduction of low calibration safety belts
which, in conjunction with the new optimised airbags with programmed retention (high
output for driver: 45 litres, and tapered for passenger: 90 litres) bring a significant
gain in protection for driver and passenger, who also benefit from two double side airbags
(head and thorax).
The passenger airbag can now be locked via a key switch, so it is now possible to fit a
rear-facing child seat on the front seat.
Ahead of European standards, the 406 also has improved head restraints and fitted a
third rear head restraint in the saloon, as in the estates. All models will now have five
head restraints.
Finally the rearrangement of electrical equipment and the improvement in practicality
have led to the design of a more visible and isolated hazard warning button which is more
easily identifiable. The same applies to the electric window buttons arranged on the doors
and a multi-function display which can indicate an open door for example.
Active safety is at a high level thanks to the high performance suspension with forged
steel wishbones at the front and multilink units at the rear, and is further enhanced by
an improvement in tyre rating, now 195/65 R15 on 6" wide wheels right from the base
models. With ABS braking combined with electronic division of the braking force, which
improves deceleration behaviour in particular on cornering, the use of the new tyres also
helps reduce the stopping distance on the models concerned.
The new 406 - even more comfortable
Comfort is a prime motivator for a present 406 customer. This growing expectation,
synonymous with well-being and a feeling at home, is further accentuated on the new 406
with a wider range of vertical comfort, postural comfort and ergonomics, practicality,
acoustic and vibratory comfort, driving aids and a more subjective dimension of visual and
tactile comfort.
Vertical Comfort
Renowned for its ride comfort and excellent rolling behaviour, the 406 continues to
make progress with the use of pressurised valve dampers which improve vertical control at
low speeds in particular.
Postural Comfort and Ergonomics
The ergonomic changes to the new 406 improve the position of the body in relation to
the internal environment of the car and so create a more relaxed driving experience and
preserve onboard tranquillity.
As seats represent a major component in postural comfort, the 406 in particular offers
textile seating in a more geometric design which offers greater leg support without
affecting the comfort of smaller drivers. The adjustment options have now been extended to
include the driver's seat height on all models, a seat base adjustment on almost 80% of
models and integral lumbar support on all seat backrests. In addition, the SV version is
fitted as standard with electric controlled seats which are further enhanced by memory
units and leather trim.
Front passengers in the new seats now have access to a new arm rest with totally
redesigned ergonomics which offers greater support for the elbow (+ 5 mm), an extra length
of 5 mm and a more comfortable height (+ 40 mm).
Improvement in Practicality and Onboard Lifestyle
Traditionally faithful to the 3 box saloon for its balance of style and character,
Peugeot have designed the 406 right from the first generation with modular rear seating
able to expand the luggage space when required and offer a practicality close to that of a
2 box design.
The new design of the rear parcel shelf panel enhances this practical dimension and
increases the useful height of the boot by 40 mm, to take two large rigid suitcases on top
of each other or standing upright.
This new panel design however does not detract from the original features including
sunblind, storage compartment and speakers.
On this occasion, the rear seat back locking system has been redesigned. These are now
self-locking and isolate the boot. The fold down is now controlled by two handles located
below the parcel shelf, marked in red and far more accessible as located in the entrance
to the boot.
Life on board is also improved in the new 406 by new features intended to assist the
driver and passengers. Hence the new steering wheel with its magnesium frame is now
lighter and has the horn push located in the centre, activated from all parts of the
centre pad. The centre console now has a noise damping carpet at the front and two cup
holders with waterproof base in the rear. The rearrangement of the electrical architecture
now includes a multi-function display with information relating to time, date or radio,
external temperature and the on-board computer.
Also, because of the extension in service intervals, it is now possible to monitor
firstly the oil level before starting the engine, on an indicator located in the
dashboard, and secondly the distance to be covered before the next service.
Comfort and practicality are also expressed in the range of new equipment available and
the wider variety. The climate control system with automatic adjustment of temperature and
air flow has evolved with a control panel and LCD screen which are now easier to
understand. Climate control is fitted as standard from the GLX level instead of the
previous non-regulated air conditioning. The air recycling feature is now activated by an
assisted push-button.
Electrical Equipment
As another innovation, the on-board electrical equipment on the 406 has been
re-arranged to offer greater user comfort.
The Intelligent Control Box (BSI) now forms part of a multiplexed network. This
connects the dashboard, the onboard navigation and the car radio on the LCD display and
the CD changer. All these systems communicate with each other more effectively than
before.
The new dashboard with its chromed round dials and redesigned graphics now incorporates
a service indicator and oil level indicator on all models.
The dashboard lighting rheostat for the display is on the left of the dashboard and,
with the bulbs lit, gives the intensity of daylight. All lit controls have the same
intensity. The interior and door sill lighting now has a 10 second delay.
The audible indicators for flashers, open door, lights on and anti-theft key come from
a small speaker fitted in the dashboard.
The two comfort features of practical nature taken from the coupé pack are now offered
on the top range 406. These are the external door mirrors which fold back electrically
against the bodywork and the interior electro-chromed day/night rearview mirror which
automatically adapts the mirror tint to the light conditions to avoid any dazzling.
The new audio units fitted to the new 406 all have steering wheel controls and remote
display. One has a volume variation as a function of speed and its performance can be
increased further with a JBL hi-fi system fitted with separate amplifier. With the JBL
hi-fi system, there are two tweeters at the front with two mid-range tweeters, two woofers
in the front doors and four coaxial speakers (two woofer-tweeters) on the rear parcel
shelf. At the user's request, the display indicates the settings of the various speakers.
Comfort and ease of use are reflected even more clearly in the on-board navigation
system offered on the new 406.
This system mainly comprises a CD-Rom reader in the right wall of the boot and a GPS
antenna located beneath the dashboard visor. The guidance system uses a monochrome graphic
display and voice synthesizer for the manoeuvres required.
The guidance system is selected very simply using the infrared remote control.
Visual, Tactile, Acoustic Comfort
Seated inside the car, the driver will quickly notice the change in interior ambience.
