With its bold, sporting design, Peugeot has given the new 407 range a high-tech specification that provides character, dynamism and real-world driving pleasure in equal measure.

The new 407 takes the market segment into new territory, with its dynamically engineered chassis featuring new double wishbone front suspension and multi-link rear suspension, a comprehensive safety package and an advanced engine line up that includes both refined and powerful petrol engines with new, cutting-edge diesel technology.

'Purposeful' is the word that best describes the exterior styling of the 407. The stylists have created a balance that is achieved through a long bonnet and a compact rear. Viewed from any angle, the 407 has uncluttered, taut lines and possesses a look that is truly unique in the market place.

And with prices starting from as little as $42,790, the 407 truly offers exceptional value for money.

Regional Director for Australia and New Zealand, Mr. Philippe Mady from Automobiles Peugeot, was pleased to announce the 407 pricing, "Peugeot has been a success story in Australia especially in recent years, and I am sure that the all new 407 will be instrumental in continuing this success."

"The 407 was only launched in Europe in April, and we are excited that we have been able to deliver this stunning car, which is in high demand world-wide, to the Australian market in only 5 months time."

Rob Dommerson, Managing Director of Peugeot Automobiles Australia, thanked Philippe for the 'special delivery', "To be able to launch the 407 only a few months after its debut is fantastic, and we are sure that the Australian public will also be pleased to know we are one of the first markets outside Europe to take delivery of this exceptional vehicle".

"Peugeot 407 customers will also be pleased to learn that the outstanding pricing announced today already reflects the fall in next year's duty rate. They will be amongst the first to benefit from the reduction of the import tariffs for imported cars, due to take effect on January 1, 2005. The move will prove quite a windfall for those who will take delivery before the end of the year, who therefore will not be disadvantaged in any way."

Pricing and Specification

The Peugeot 407 offers outstanding value for money, with standard equipment and safety levels that set a new benchmark in its class.

Items you would expect to be on the 'options list' are standard, and the 407 boasts equipment levels that compare very favourably to much more expensive prestige vehicles.

The New 407 – Overview

Petrol or Diesel HDi - a wide range of engines
The petrol and diesel HDi engines that power the 407 feature the latest technology and provide numerous benefits to the customer - 6-speed manual gearboxes standard across the range, 4-speed or 6-speed automatic gearboxes, compliance with Euro 4 environmental standards and the inclusion of a particulate emission filter (FAP) on diesel versions.

Choice of power trains
The 407 range is equipped with a choice of power trains based on two petrol engines ranging from 2.2 litres to 3.0 litres and a 2.0 litre HDi diesel engine fitted with a particulate emission filter (FAP).

The 407 is fitted with a 6-speed manual gearbox as standard, and is also available with an optional electronically controlled 4-speed automatic 'Tiptronic' gearbox with sequential control. In the case of the V6 'SV' model - an entirely new automatic 6-speed AM6 gearbox is fitted, developed and built by Aisin A.W. in Japan. A world first for a high torque front wheel drive vehicle.

Petrol engines:
The 407 'ST' begins the range with a 2.2 litre engine with a power output of 116 kW and 217 Nm of torque at 3,900 rpm, combined with a 6-speed manual gearbox or a 4-speed automatic auto-adaptive gearbox with 'Tiptronic System' sequential control.

The 3.0 litre V6 engine from the 'SV' range offers a power output of 155 kW and torque of 290 Nm at 3,750 rpm. This engine incorporates a variable valve timing system (VVT) that allows more linear acceleration and a new exhaust with an active dual-mode system offering superior performance at high engine speeds and improved noise insulation. It is combined with an all-new 6-speed automatic gearbox equipped with the 'Tiptronic System' sequential control to enhance overall performance.

Diesel engines
The 407 will feature the latest in HDi Diesel engine technology, offering high performance in terms of dynamism, driving economy and respect for the environment:

A 2.0 litre HDi with particulate emission filter (FAP) developing 100 kW and 320 Nm of torque at 2,000 rpm. Compliant with Euro 4 legislation, it eliminates particles by means of its FAP and is combined with a 6-speed manual or 4-speed 'Tiptronic' automatic gearbox. The engine features an air/air intercooler, a new-generation Common Rail system with an injection pressure of 1600 bar, and a variable geometry turbocharger.

In the future, the 407 will benefit from other Diesel HDi engines, in particular the 2.7 litre V6 HDi engine, the next stage in the Ford / PSA development partnership. It may also feature a wider range of automatic gearboxes.

A great driver's car...
Dynamically, the 407 is a worthy successor to the 406 - a benchmark car for so many years.

Drawing on experience and specialist know-how, Peugeot has conceived and put together a highly efficient chassis specification that covers all aspects of ride and handling. The specification consists of a chassis that makes extensive use of lightweight aluminium alloy for enhanced performance:

a front axle with double wishbones and a linked hub carrier offering superb road holding and comfort, combined with excellent directional control.

a multi-arm rear suspension with dampers inclined rearwards to optimise the internal width of the boot area.

Active safety features range from large disc brakes with a diameter up to 330 mm and a new-generation electronic stability programme (ESP), which is present on all versions. The latter comprises an anti-skid function (ASR), ABS, emergency brake assist (EBA), new individual wheel brake force distribution (EBFD), and a stability control system with particularly efficient correction of under- and over-steering. Automatic activation of hazard warning lights in the event of sharp deceleration informs following vehicles of potential danger.

...and exclusive to the V6 engine
To accompany its pedigree and performance, the V6 engine has unique suspension and steering that offers outstanding performance levels. The variable electronic suspension has four independently, electronically- controlled dampers with nine individual settings, while the car also benefits from vehicle speed variable rate power steering.

A high quality interior
Following the example of the exterior lines, the interior of the 407 exudes strength and quality. Structured around a bold central console, the interior is organised to ensure that everyone can enjoy driving and travelling together.

Open to the light...
The brightness of the interior is striking, with light diffused through almost 1.5 m² of windscreen and the long side windows.

And unique in its class, the 407 Touring features a panoramic glass roof, which gives the occupants a unique sense of spaciousness.

With a surface area of nearly 1.6 m2, extending light from the equally large front windscreen in an uninterrupted vista to the rear of the car, giving the 407 Touring a total glazed surface area of 4.82 m2. Inside the 407 Touring, the large glass roof endows the passenger compartment with space and light, creating an ambience that is open to the outside, yet also warm and intimate. Manufactured from tinted laminated glass with a thickness of 6 mm, the panoramic glass roof delivers a light transmittance in the order of 20 %, offering unrivalled views of the outside, while limiting energy filtration to 12 %.

An electric blind, consisting of four overlapping panels, folds back discreetly at the rear of the roof. Light can therefore flood into the car, or be partially or completely obscured. It is controlled by a nine-position rotary switch and includes a safety auto-reverse function.

Comfortable and luxurious seats
The front seats ensure a comfortable posture thanks to their ergonomic design and their generous range of adjustment. At the rear, the absence of a transmission tunnel creates more space for passengers, while the seats themselves provide excellent support. The rear bench seat, split 2/3 1/3, can be folded to suit space requirements without having to remove the head restraints.

Practical storage spaces
Everything that can potentially enhance comfort and practicality has been meticulously designed. The storage spaces located around the passenger compartment can be used by all occupants; the air-conditioned glovebox is accompanied by large door pockets and a cup holder and small sealed or open spaces for use as storage. The wide central rear armrest also has a folding storage space and 2 cup holders. When folded, it conceals the flap that allows long objects to be carried in the boot.

The boot, with a capacity of 407 dm³, comprises a large luggage area with two self-contained storage spaces to the side. Its generous width of 1,100 mm is made possible by the multi-arm rear suspension with dampers that are inclined rearwards. Two large suitcases can comfortably be placed side by side or one on top of the other.

The Touring adds a further dimension to storage for the 407 range.

The luggage area is an integral part of the passenger compartment and as such offers a space that is both attractive and functional. The rear tailgate and its glass windscreen can be opened independently depending on requirements in terms of access: rear screen only, to carefully store a garment or obtain access to the boot in a restricted parking space or close to a wall - tailgate fully open to reveal a low boot sill 615 mm above ground level for the loading of heavy or bulky items.

To open the rear windscreen only there is a "boot" button on the remote control, which unlocks it and releases it from its catch bolt. It can also be opened by means of the electric control located at the base of the rear windscreen wiper.

As well as a main volume of 448 dm3 plus closed side storage areas with a capacity of 9 and 12 dm3, with its perfectly parallel shape and ingenious design, it is particularly welcoming and offers excellent protection to stored items.

The tailgate opens to reveal a wide band of ribbed stainless steel, which protects the load sill over a width of 1071 mm. Behind this, a thick decorative carpet and four raised "slide bars" provide a floor covering with a minimum width of 1100 mm. Two suitcases laid flat can easily be accommodated over a length of 1020 mm.

Lined with a thick soundproofed insulation, the boot carpet is removable. It has a lifting strap extended by a support hook in the open position, providing access to a normal-sized spare wheel located in a sealed wheel well under the floor. The walls of the luggage compartment are carpet lined and feature two side storage areas behind thermoformed carpet flaps.

On the right-hand side, a six CD autochanger and a JBL bass box can be fitted adjacent to the storage space. A luggage net can be attached to the floor by means of four stowing rings and a 12 V accessory power point is available on many versions.

To ensure that the contents of the luggage compartment remain out of sight, the 407 SW has a practical, rigid, carpet-lined tonneau, consisting of a flat section, two folding flaps and a styling strip with a central handle. This design allows easy access to the luggage compartment regardless of how the rear of the car is opened, whether tailgate or rear windscreen only.

Air conditioning par excellence.
A safety feature for the driver and a source of comfort for all passengers, a vehicle's air conditioning has become indispensable.

However, air conditioning systems can have a number of drawbacks during use that are sometimes mentioned by users, such as increased fuel consumption or perceived air flow that is welcome to some but irritating to others. However, the air conditioning with automatic regulation that is fitted to all 407's comes with innovations that are designed to improve efficiency and meet the expectations of users in terms of comfort:

A 'gentle diffusion' system expels air unnoticeably via a new grille located at the top of the instrument panel and distributes the remaining airflow through front-mounted vents and special rear passenger vents.

A humidity sensor detects the onset of condensation in the passenger compartment and instructs the air conditioning system to adjust accordingly.

An 'externally controlled' compressor significantly reduces the vehicle's average fuel consumption.

A pollen filter, combined with a layer of active carbon, further insulates the passenger compartment from external pollutants. The 407's air conditioning system is offers dual-zone distribution with reference to temperature and a separate right/left distribution. All information concerning the air conditioning is visible on the multifunction screen at the top of the instrument panel.

Driver comfort
Particular attention has been paid to the driver and his or her environment, to make driving as easy and as safe as possible, but also a pleasure.

The driver's seat for example, like the passenger's, has a long cushion and a generous adjustment range - 240 mm for length, 50 mm for height, with tilt and lumbar adjustment by means of separate levers. The 'more upright' steering wheel is also adjustable for rake and depth for up to 40 mm (in each axis). It is therefore easy for individuals with a larger build to adopt a comfortable driving position. For ultimate comfort, memorisation of all settings - steering column, seats, door mirrors - is available on certain versions, with remote-control recall of stored settings.

Driving aids and audible warnings to help driver concentration
To assist with parking manoeuvres, standard parking sensors on all models evaluate distances.

Similarly, to assist the driver in adhering to self-imposed speed limits, a variable cruise control is also standard, which can be coupled with a variable speed limiter with a slightly delayed application. Also standard is a system for the direct detection of low tyre pressure or punctures, with identification of the faulty wheel and an audible warning and message on the multifunction screen.

See and be seen - an important safety criterion
Lighting on the 407 is assured by double reflector halogen headlamps or on the SV models a high-performance Xenon dipped beam. The latter features automatic height correction and a headlamp wash function. In addition, all 407s are equipped with front fog lamps mounted in the skirt.

Windscreen wipers play an important role in visibility. The 407 is equipped with new powerful single-blade butterfly arms, each with its own motor. Extra-flat, they remain very discreet and follow every contour of the distinctively curved windscreen. All versions have an automatic rain sensor function, coupled with automatic activation of the headlamps.

The driver has an anti-glare rear-view mirror that uses electro-chrome technology to prevent the driver from being dazzled at night making driving more comfortable, while automatic headlamp activation improves the comfort and safety of occupants and other road users.

Advanced passive safety - eight air bags standard
To withstand impact, the extended aluminium sub-frame dissipates impact forces in two directions - upper path and lower path - while in the event of an impact engine movement is controlled by reinforced mountings and the steering column retracts by 80 mm.

Occupants also benefit from high-performance restraint systems. Front passengers have active 'anti-whiplash' head restraints, 'SMART' adaptive front air bags coupled with pre-tensioning seat belts and force limiters, plus a 'fasten seat belt' indicator, as well as side air bags in the sides of the seats and curtain air bags that are shared with the rear passengers.

Rear passengers benefit from seat belts fitted with a 'fasten seat belt' audible warning, as well as rear side air bags mounted in the door panels coupled with pre-tensioning seat belts.

To give all occupants an added sense of security, the doors and boot lock automatically from a speed of 10km/h. This operation is programmable by the user. Electronic child locks are also fitted as standard.

On-board communication

Integrated technology
The 407 is equipped as standard with a six speaker, remote controlled CD/radio system.

Additionally, thanks to two analogue inputs, it can also incorporate an MP3 player.

A JBL hi-fi system can be combined with any of the car radio installations. With an output of 240W, it includes ten speakers in eight locations and a bass box (subwoofer) located in the side storage area of the boot, just above the CD stacker. Standard on SV models.

Engines

Petrol engines
All the petrol engines have four valves per cylinder and a motorised throttle housing which, controlled electrically by the engine ECU, enhances driving comfort while at the same time reducing emissions. It also allows a dialogue between the engine and the 'electronic stability programme' (ESP).

2.2 litre petrol - EW12 J4
With a capacity of 2,230 cm³ (bore 86 mm, stroke 96 mm), it develops a maximum power of 116 kW at 5,650 rpm, and a maximum torque of 217 Nm at 3,900 rpm, 92% of which is available between 2,000 rpm and 5,500 rpm. To reduce the natural vibrations transmitted by a 4-cylinder engine during acceleration, this engine is equipped with two balance shafts driven by the crankshaft. To encourage a high torque at low engine speeds, the intake camshaft is equipped with a variable timing system (On/Off, VTC) offset by up to 20° with respect to the crankshaft. Engine management is by means of a type 4 MP Magneti Marelli unit controlling a phased sequential injection and an ignition, also sequential, with one ignition coil per cylinder.

3.0 litre Petrol ES9 A
This V6 engine with a capacity of 2,946 cm3 (bore 87 mm - stroke 82.6 mm) develops a maximum power of 155 kW at 6,000 rpm and a maximum torque of 290 Nm at 3,750 rpm.

To obtain good flexibility at low engine speeds and power, the intake camshafts are equipped with a continuous variable valve timing system (VVT) with an angular variation of between 0° and 40° with respect to crankshaft timing. This is carried out one degree at a time and allows optimal filling of the combustion chambers regardless of engine speed. This characteristic makes the engine both flexible and powerful. Engine management is by means of a Bosch M4 7.6 unit with a phased sequential injection and an ignition system using six individual 'pencil' ignition coils.

Diesel engines
The HDi engine available on the 407, with a capacity of 2.0 litres is equipped with the latest-generation high-pressure 'Common Rail' injection system. Internal pressure can vary between 250 bar and 1,650 bar according to the demand formulated by the computer software in relation to engine speed and engine load. The rail is connected to Siemens injectors, with a 'piezo-electric' control head. All are equipped with six injection apertures that ensure a very fine spray directly in the combustion chamber.

A special feature of the injection system is the ability to manage six potential injection phases: two injections to control combustion noise, two main injections to obtain torque and power, as well as a good compromise between noise/emissions/consumption, and two post-injections for regeneration of the particulate emission filter (FAP).

The diesel engine is fitted with a second-generation particulate emission filter (FAP) that retains particles and then incinerates them according to an innovative process specific to Peugeot common rail technology, in conjunction with a fuel additive Eolys II.

The filter incorporates an 'intelligent maintenance' strategy, which, according to the type of driving, determines the mileage and even the best time to carry out regeneration. The filter service interval has been increased, with replacement now scheduled during the 80,000km service. The FAP Peugeot diesel engine satisfies the strict EURO IV emission standards.

HDi 2.0 litre Diesel DW10 BTED4
With a capacity of 1,997 cm³ (bore 85 mm, stroke 88 mm) and incorporating a 16-valve cylinder head with double overhead camshafts, it develops a maximum power of 100kW at 4,000 rpm, and a maximum torque of 320 Nm at 2,000 rpm.

The 'over boost' function is activated when the engine is under full load between 1,500 rpm and 3,200 rpm, and increases torque by approximately 6.3 %.

Safety

Passive safety
Eight air bags for unrivalled peace of mind!
The specification of the wheels and suspension of the 407 provide excellent dynamic qualities and outstanding passive safety. The innovative structure and the restraint systems present in the passenger compartment, together form an outstanding protective shield that makes the risk of injury more unlikely in the event of impact. At the same time the design ensures maximum comfort for the occupants.

The 407 recently achieved a 5-star ENCAP crash test result.

The front seats
The driver is protected in the event of impact by a twin generator, dual volume 'SMART' front air bag, the pressure and volume of which when deployed depend on the severity of the impact and the driver's weight. After deployment, the volume of the bag may vary between 42 litres and 83 litres. The driver can also count on a steering column that collapses by 80 mm in the event of an impact In the outer part of the seat, a side air bag with a capacity of 10 litres protects the chest and abdomen in the event of side impact, while the driver also shares the head protection afforded to the rear passenger by the 23-litre curtain air bag.

The front passenger similarly benefits from a twin generator, single volume SMART front air bag with a capacity of 120 litres, adapted to the severity of the impact.

Both driver and front passenger have the benefit of pre-tensioning seat belts and force limiters rated at 450 DaN that work 'in tandem' with the front air bag to guarantee optimum protection.

These seat belts are equipped with a double 'fasten seat belt' audible warning, firstly by means of a visual indicator on the instrument panel, then in the form of a buzzer once the car reaches a speed of 9mph. The passenger seat is of course equipped with an occupant detection system.

In the event of rear impact, 'active front head restraints' prevent whiplash by keeping the head restraint in close contact with the occupant's head, thereby avoiding hyperextension of the neck.

The rear seats
Passengers in the rear outer seats have curtain air bags for head protection and three-point seat belts equipped with force limiters rated at 600 DaN. These passengers benefit from side air bags coupled with inertia reel pre-tensioning seat belts. These side air bags are located in the rear door panels and have an individual capacity of 9 litres. Like the outer seat belts, the central rear seat belt is a three-point inertia reel belt, featuring a web lock.

To encourage rear passengers to wear their seat belts and also to provide a warning should a child become unattached, the number of fastened rear seat belts is counted and displayed clearly on the multifunction screen when the ignition is switched on. Any change in status is indicated jointly by a warning light on the instrument panel, a warning message on the screen and a buzzer.

Steering

Steering and Braking
Recognised for its precision and the accuracy of the information it provides, rack and pinion steering has been retained for the 407. To achieve the best possible power steering / engine combination, in conjunction with tyre dimensions and according to the specific model, three different power steering systems have been developed for the car. The steering guarantees both driving precision and weight that adapts to all possible situations.

Electro-hydraulic power steering is supplied by an electro pump unit controlled according to the speed of the car and the speed of rotation of the steering wheel. In addition to a natural tendency to reduce fuel consumption and therefore CO2 emissions, this system significantly increases driving comfort.

Finally, the 6-cylinder 407 is equipped with variable hydraulic power steering. With this system, power steering is supplied by a computer-controlled valve that takes into account a multitude of data, such as vehicle speed, engine speed, turning angle and steering wheel rotational speed. This device further enhances performance by offering improved response and comfort in all circumstances.

Braking
On the 407, braking is optimised to each car's weight and level of performance. Common features include two separate 'X' circuits, braking assistance, and four generously proportioned discs, two of which are ventilated at the front.

All cars also feature an anti-lock braking system (ABS) with integral braking control on individual wheels, including distribution between the front and rear axles with electronic brake force distribution (EBFD) and a new system allowing independent control of the RH and LH wheels. In addition, the 407 is fitted with emergency braking assistance (EBA) and automatic activation of the hazard warning lights in the event of sharp deceleration, which operates independently of the ABS.

While ABS prevents a wheel from locking during emergency braking and therefore preserves the ability to steer the car, control of individual wheels guarantees optimum braking efficiency and stability of the car during braking, particularly in bends without ABS regulation or dynamic stability control (ESP). Emergency braking assistance (EBA) provides maximum braking power according to the speed at which the brake pedal is depressed. Automatic activation of the hazard warning lights during sharp deceleration informs following vehicles of an abnormal situation, leaving the driver free to concentrate on controlling the vehicle.

The ESP
For the 407, engineers have included a latest generation electronic stability programme (ESP) compatible with systems controlled and installed on all versions, such as individual wheel braking and ABS.

To utilise the high potential of the wheels and suspension of the new car, the latter has been developed with and without ESP in order to offer a high level of active safety whilst preserving genuine driving pleasure. The ESP developed in partnership with TRW includes an ABS system, an anti-skid function (ASR) acting on engine management and the brakes, and an emergency braking system, all combined with integral control of braking on individual wheels to ensure the best possible efficiency and optimum stability of the car.

The ESP also incorporates the 'Stability Control' ECU, which, thanks to a steering wheel sensor and a yaw sensor, can detect any tendency to under- or over-steer. As a result of detection, the computer orders a correction to be carried out to ensure, as far as the laws of physics allow, that the car follows the direction requested by the driver.

Two software programs incorporated in the computer have been designed and developed specially for the 407. For correction of under-steer and to return the car to its intended direction as quickly as possible, the correction is carried out on the two front wheels and on the inside rear wheel.

For over-steer, the correction involves two distinct operations. Firstly, it takes the form of a preliminary command issuing an initial level of regulation that stabilises the vehicle in a manner transparent to the driver. This preliminary command 'reduces' the system's response time in the event of the need for more strenuous intervention.

Secondly, the software logic adapts itself to the driver's driving style and to emergency situations. Because the stability control is able to detect, for example, sporty driving and high-speed evasive manoeuvres, its regulation in the first case is slightly delayed in order to improve the car's agility. This system prevents unnecessary intervention and ensures the outstanding dynamic character of the 407.

Structure

Structure and engineering
The structure of the 407 uses platform three from the middle and upper segments of the PSA range. However, it has been significantly adapted to meet the demands of this new car - particularly in terms of driving dynamics and safety.

The body has a torsional rigidity of 0.77 mrad - never before attained on a Peugeot sedan.

This high rigidity ensures the optimum performance of the suspension and enhances road holding and active safety, as well as driving dynamics and comfort.

In addition, special attention has been given to the front structure to improve passive safety.

Here, a new lower structure absorbs impacts and adds its benefits to the 'classic' top structure made up of the chassis legs. Two thirds of the energy is absorbed via the top structure and one third via the bottom structure. This bottom structure consists of a long sub-frame, made up of a standard sub-frame with the addition of extensions, a front cross member, energy absorbers and a pedestrian beam covered by impact absorbing foam.

With the exception of the pedestrian beam, all parts of the long sub-frame are manufactured from aluminium. This front structure represents a new strategy of impact absorption. By creating better distribution of forces it combines the attractive features of a car rigid enough to offer protection in the event of a high-speed front impact, while at the same time supple enough to offer protection to pedestrians and ensure compatibility in collisions with lighter vehicles.

An engine mount/restraint device anchors the engine to the sub-frame, and completes the protection against high-speed front impact by limiting the intrusion of the engine into the passenger compartment.

Pedestrian protection is ensured by the structural suppleness of the front of the car and by means of shock absorbing foam padding fitted to the lower part of the pedestrian beam - the final element of the bottom structure, and to the top of the bumper bar. Finally, the bonnet limits the effects of this type of impact even further, since its rigidity, and its distance from the mechanical components it houses, have been optimised to reduce head injuries.

Reparability also benefits considerably from this design, which is optimised by a removable front section to the long sub-frame, a bolted end beam on the front chassis leg and, at the rear of the car, a bolted composite beam protecting the rear panel.

Protection against side impact is ensured by the design of the body frame and superstructure, which absorbs energy and preserves a survival cell for all occupants.

The doors are equipped with strengtheners, and tubular bars at the front enhance rigidity by creating a solid span between the 'A' posts and B/C posts and the rear wheel arch.

Much work has been devoted to optimising the aerodynamic qualities of the 407, which has a drag coefficient or Cd of 0.29 versus 0.32 for the 406. These results were obtained thanks largely to the overall fluidity of style, with specific enhancements (lower front panel and tailgate), significant under body shielding, and the seamless styling of the front of the vehicle.

The structure of the 407 is guaranteed for twelve years against corrosion of any kind, while paintwork comes with a three-year warranty.

Transmissions

The 407 is fitted with engines that can be combined with either a manual 6-speed or with an electronic 4-speed or 6-speed automatic 'Tiptronic' auto adaptive gearbox.

The 6-speed manual gearboxes are adapted to the characteristics specific to each engine. These differences concern gear and axle ratios, which are shorter with the petrol engine than with the Diesel engine.

The automatic gearboxes feature a 'Tiptronic' sequential control system and are mounted transversely at the end of each engine.

The 6-cylinder petrol engine - with a power of 155 kW and 290 Nm of torque - is coupled uniquely with a new 6-speed automatic gearbox.

Developed by Aisin A.W.* in accordance with specifications issued by the PSA Peugeot group, this gearbox is genuinely innovative, allowing for the first time ever, a 6-speed transmission to be mated to a high-torque, transversally mounted engine. Its torque capacity, which extends to 290 Nm, makes it compatible with the group's future engine developments.
*Aisin A.W. is a Japanese equipment manufacturer and a world leader in the supply of automatic gearboxes.

Schematically, its underlying principle is to use the gear ratio combinations of two epicyclic gear trains, one single, and the other double. The assembly is controlled by just five friction clutches managed by a compact integral computer.

This principle allows a compactness and weight hitherto unheard of for a 6-speed gearbox, on a par with those of 4-speed automatic gearboxes and better than those of automatic 5-speed transverse gearboxes with a similar torque capacity.

The weight of the 6-speed gearbox does not exceed 93 kg and is therefore comparable (90 kg) to that of a 4-speed automatic gearbox such as the one that equipped the V6 406 for example. The short first gear gives the car verve when starting off and the six gears fully exploit the engine's potential, with a slight drop in engine speed accompanying each gear change.

The car's dynamic performance is therefore significantly enhanced compared to the previous performance of the 406 V6 automatic gearbox. Furthermore the gearbox offers the possibility of locking the converter* in all gears, which benefits fuel consumption. Moreover, the 'extended' sixth gear reduces both fuel consumption and noise levels. *lock up function

With the ability to recognise the style of the driver, special attention was given to the quality and speed of automatic gear changes. Driving quality is also enhanced by two possible control modes: one automatic and auto adaptive, for peaceful and stress-free driving, the other more active, thanks to the 'Tiptronic System' sequential control.

An indication of which gear is engaged and of the selected programme (normal, sport or snow) is shown within the multifunction display on the instrument panel. For added safety, the gearbox also has a 'shift lock' function that prevents release of the Park position (P) while the engine is running unless the brake pedal is depressed at the same time. Similarly, a buzzer is activated when the driver opens his door after switching off the engine without having returned the gear lever to the Park position.

Wheels and Suspension

Wheels and suspension
When Peugeot's engineers set out to design the wheels and suspension for the new 407, they looked for an optimal solution that would ensure the very best ride and handling characteristics to satisfy the most demanding of customers.

The expertise of our engineers in this field therefore allowed them to conceive, design and develop solutions that provided outstanding road holding, dynamic safety, driving pleasure and comfort.

Based on a floor pan exhibiting a high torsional rigidity, the choice fell naturally on a high-tech design that encompasses a generous use of lightweight materials with double wishbone front suspension and an integral multi-arm rear suspension with the damper and springs inclined rearwards.

At the front, the double wishbone drop link design, in part derived from Peugeot competition cars*, allows the separation of vertical suspension travel and deflection. With this new design, the wheels turn about an axis formed by two ball joints located between the hub carrier and a hub carrier support (or strengthening strut). Vertical movement is managed by three flexible joints situated between the hub carrier support and the two wishbones.

This design ensures a small hub carrier angle with relatively little wheel axis offset (caster) and preserves optimum body control characteristics. In terms of performance, this results in very positive directional control under all circumstances, on both rough and deeply rutted roads. In addition, it virtually eliminates steering adjustments, giving outstanding, precise feel when cornering, it reduces sensitivity to wheel imbalance and adds suppleness to the suspension.

Compared to the first-generation multi-arm rear suspension that made its appearance on the 406, the all-new rear suspension of the 407 differs essentially by the inclusion of an inclined spring and damper assembly and of a longitudinal arm linked to the hub carrier to ensure longitudinal control.

The entire suspension is assembled on a light-alloy cross-member with mechanical characteristics that not only give the suspension static geometrical precision, but also ensure rigorous dynamic positioning of each wheel, guaranteeing excellent steering and ensuring that the car remains balanced under all circumstances. Most constituent parts of the axles are manufactured from light alloy, with the more complex of them using Cobapress aluminium*.

The front axle
Under the engine compartment of the 407 there is a long light-alloy sub-frame formed by two distinct sections. The front section of the sub-frame consisting of welded aluminium sections is rigidly attached to the rear cross member. Weighing less than 6 kg, it essentially performs three passive safety functions, namely: support of an impact beam to 'contact' the legs of pedestrians; repairability, thanks to a pre-deformed absorption zone; and, in the event of high-speed impact, absorption of energy through a programmed deformation.

The rear section, consisting of a cast aluminium cross-member, is dedicated to the suspension and is very strong, being joined to the structure by means of vibration absorbing mountings. It weighs only 15 kg, i.e. 8 kg less than any welded-steel equivalent. This section is located so as to absorb braking forces transmitted by the front movement of the wishbone.

Each suspension unit has a cast-iron hub carrier connected to a steering rod. Two ball joints with a tapered fit connect it to the hub carrier support and are thus able to accommodate different types of deformation between the cast iron (hub carrier) and the aluminium (hub carrier support).

*Aluminium, Cast-Transformed-Pressed to obtain a cast aluminium part of complex shape possessing the same mechanical properties as a forged part.

The welded assembly of the aluminium hub carrier support is an impressive component and plays an important role, since it supports both hub carrier ball joints, as well as that of the anti-roll bar rod, those of the spring and damper and the double suspension wishbones. This multi-function hub carrier fits around the drive shaft and weighs only 4.250 kg.

When driving, wheel geometry, is also maintained by the double wishbone configuration. On the sub-frame side, the lower wishbone, manufactured from forged steel, has two flexible mountings of differing hardness. It operates in conjunction with rubber/polyurethane composite links of varying rigidity: axial (braking forces for the front movement) and radial (steering for the rear).

The upper wishbone, manufactured from high-strength steel plate, supports four traditional flexible mountings, two on the hub carrier and two on the upper strut mounting rigidly attached to the structure. Its main function is to control the direction of the wheels. The upper bearing support manufactured from Cobapress aluminium provides the interface with the body shell and accommodates the upper mounting of the spring and damper assembly.

The front axle naturally incorporates a 23.5 to 25 mm diameter anti-roll bar. Mounted on two bearings rigidly attached to the sub-frame cross member, each of its ends is connected to the hub carrier support by means of a link with two ball joints. This construction greatly enhances the efficiency of the anti-roll bar by ensuring accurate and fast mechanical transmission of the slightest movement of the body during cornering.

The rear suspension
The multi-arm rear suspension is supported by an aluminium cross member. It consists of two cast-iron sections connected by a profiled tube, to which they are welded. The assembled cross member weighs 14 kg and is joined to the structure by means of four flexible mountings with inbuilt radial stiffness and axial flexibility. This extremely rigid cross member provides the interface with each suspension unit. Each one has an upper wishbone, two lower transverse arms, one longitudinal arm, a hub carrier, a spring and damper assembly and a solid anti-roll bar (19 and 19.8 mm diameter) that connects the suspension units. The anti-roll bar is maintained by two bearings rigidly attached to the rear floor. It is connected to each hub carrier by means of a link with two ball joints and plays an important role in transferring loads during cornering.

The hub carrier, manufactured from Cobapress aluminium, has a ribbed design and is specially strengthened to resist operating stresses. It is unaffected by the forces and torques transmitted via the wheel, in particular braking torque, which it simply transmits to the different suspension arms.

The upper wishbone, also manufactured from Cobapress aluminium, operates vertically and has two traditional flexible joints rigidly attached to the cross member. The third, connected to the hub carrier is special since it has a high radial stiffness (corresponding to the wheel axis) and axial flexibility to 'gently' absorb peak longitudinal forces. The upper surface of the wishbone makes contact with a bump stop located on the structure.

In its lower section, the suspension unit has two transverse arms manufactured from pressed steel that connect the hub carrier to the cross member. The rear arm contributes to the lateral integrity of the hub carrier and absorbs dynamic vertical stresses. The adjustable front arm, or track control arm, absorbs transverse stresses and at the same time controls tracking. Its static adjustment is finalised during assembly of the suspension on the cross member.

Still in the lower section, each suspension unit has a third, forward-facing arm. This provides the link between the hub carrier and the underframe and absorbs longitudinal forces. Manufactured from Cobapress aluminium, it filters impacts and helps to control axle geometry and movement as it exhibits radial flexibility and axial rigidity.

Lastly, there is a spring and damper assembly, inclined rearwards and connected between the cross member and the hub carrier. Since the purpose of the 407's rear suspension is to preserve the comfort of its occupants, it also ensures dynamic steering of the car thanks to rigorous control of wheel geometry in all circumstances.

Shock absorption
Upholding the Peugeot tradition and following the example of its predecessors, the 407 is equipped with dampers developed 'in-house' at the front and rear. These spring and damper assemblies, through their design and their positioning, guarantee efficient support for the body as well as a high level of filtering to ensure optimum road holding and dynamic comfort. On each suspension unit, the naturally varying flexibility of a bump stop helps to optimise vehicle stability whilst preserving vertical comfort.

The gas pressure dampers incorporate multi-valve technology (four valves per damper) and their shock absorption characteristics correspond to the weight distribution of each version, as well as to the flexibility of the corresponding springs.

With the 6-cylinder engine, shock absorption is controlled electronically and variable according to nine distinct settings. Contrary to previous solutions that operated on the basis of individual axles, on the 407 each of the four electronic dampers are controlled separately thanks to the presence of a movement sensor rigidly attached to each wheel.

This new design allows adaptive performance on driver behaviour, as well as the forces transmitted by the road. This makes it possible, for example in a straight line and at a constant speed, to enhance comfort on bumpy roads in terms of bounce, pitch and roll. Additionally, since automatic stiffening takes account of the mass applied to each wheel, it guarantees road holding in bends, and during low- and high-speed braking and acceleration.

A push-button allows optional reinforcement of variable damping for greater firmness, to give the car an even more dynamic feel.
