Peugeot 4007 (2007)

The interior is trimmed throughout with a strong Peugeot identity. An aluminium coloured finish is used to highlight air vent surrounds, grab handles and other key controls. The seats are manufactured from a high-quality three-part fabric, adding a further sporty touch. This also applies to the seats in the versions trimmed in high quality leather that also features attractive visible stitching.

4007 dimensions

With a length of 4.64m and a width of 1.80m, Peugeot's SUV stands out by its height (1.67m) and above all by its ground clearance (174mm), a sign of its ability and capability to venture off road. Equipped with 5 doors, the 4007 has seating for up to seven people, the rear two seats of which fold flat into the rear boot floor space.

Designed with versatility in mind,
its has a highly modular load area to permit a boot volume of up to 510 dm3 under the parcel shelf (VDA standard) in the 5-seat configuration, which can be extended to 1686 dm3 in the two-seat configuration.

In addition, due to its split tailgate configuration, the flat loading sill height is only 600mm from the ground.

A benchmark structure

The body structure has been developed with the Mitsubishi Motors Corporation and evolves their wealth of experience for safety and all-terrain capability in building 4x4 SUVs of great reputation.

Much work was carried out to achieve a structure that is both extremely rigid for rigorous vehicle handling yet deformable in key areas to absorb energy to protect occupants in the event of an impact. The side members have an octagonal cross-section which helps to control the dissipation of energy. As a result, in the event of frontal impacts at low speed, energy is absorbed by the front section of the side member and not transmitted rearward, a by-product of which minimises insurance repair costs.

The front side members located at the back of the centre of the bulkhead panel and lower structure by three 'legs'. These legs disperse the energy generated across each structure. Reinforcement bars located in the doors also protect occupants in the event of a side impact, as does impact absorbing padding inserted into the door panels.

Being a 4x4 vehicle and therefore being taller than traditional cars, the structure has been designed to ensure 'crash compatibility' in the event of collision, providing effective protection to occupants of all affected vehicles.

The power train, mounted in the transverse position, is positioned within the chassis which is reinforced by a central cross member under the engine. Hydraulic mountings, combined with a set of reaction link rods, reduce the transmission of engine vibration.

The roof is constructed of aluminium to lighten the upper vehicle weight by 5 kg and thereby reduces the centre of gravity by around 4mm.

The full CAN electronic architecture is similar to that found on current Peugeot vehicles.

Finally, to preserve the ground clearance and at the same time give the car an adequate range, the fuel tank, with a total capacity of 60 litres, is cleverly divided into two, located on either side of the rear transmission and connected by a transfer pump system.

Wheels and suspension

4007 benefits from the latest technologies by featuring large alloy wheels and tyres capable of high levels of on-road refinement combined with an off-road grip capability which extends the versatility for leisure use, characterised by modern-day SUVs.

The 4007 features independent suspension on all four wheels, with McPherson type struts at the front, with a 22mm anti-roll bar and a multi-arm design at the rear, with a 20mm anti-roll bar.

A lot of attention has been paid with the tyre manufacturers to develop an 18" tyre (225/55 R18) suitable for both on-road and modest off-road driving. A 16" tyre (215/70 R16) has also been developed for more extreme leisure pursuits where the vehicles driving abilities in under poor conditions are more important.

Peugeot engineers have specified double piston calipers with front ventilated discs to maximise braking efficiency. The front brakes have a diameter of 294mm x 24mm and at the rear, solid discs with a diameter of 302mm.

4007 features pump-assisted hydraulic steering modulated according to engine speed. Its performance has been fine-tuned in conjunction with tyre development to give the assured feeling of control characterised in other Peugeot vehicles. Qualities of linearity, accuracy and self-centring ensure fluid handling and an excellent level of driveability in all situations.

Body rigidity has benefited from Peugeot's chassis and dynamic handling expertise to give the 4007 the driveability similar to a modern hatchback, while maintaining a level of comfort in keeping with the car's versatile capabilities> Spring stiffness and damping characteristics have been tuned specifically to the vehicle and its 2.2-litre power unit.

Electronically controlled 4-wheel drive

The 4007 is equipped with an innovative 'on demand' 4-wheel drive system. An electronic system controls a viscous clutch located ahead of the rear axle to distribute torque between the front and rear axles to thereby optimising engine and transmission performance. This technology is developed by the Mitsubishi Motors Corporation, a recognised specialist in 4-wheel drive transmissions.

The transmission features a transfer box located on the gearbox output and directs torque to the rear axle via a longitudinal propshaft. An Electronic Control Unit (ECU) calculates in real time parameters such as the vehicle speed, steering wheel angle, the difference in speed of rotation of the front and rear wheels and the level of acceleration, in order to electronically control the viscous clutch assembly.

4-wheel drive on demand

The driver can select three driving modes by selecting the mode on a central knob located between the two front seats:

2-wheel drive mode (2WD)

This mode corresponds to driving on tarmac when the driver does not expect any loss of traction (a dry road). The vehicle operates most efficiently in front-wheel drive (2WD), thereby reducing fuel consumption.

Automatic 4-wheel drive mode (4WD)

This is the vehicle's normal operating mode, with torque distribution between the front and rear axles controlled by the ECU. This provides the assurance of optimal road holding regardless of surface conditions. The table below provides a summary of torque distribution between the two axles according to different driving conditions.

4-wheel drive lock mode (4WD)

Used under conditions of reduced traction, four-wheel drive becomes permanent with a higher distribution of torque to the rear wheels compared to the 4WD mode. This is the case in particular at low speed, where 50% of the additional torque will be distributed to the rear wheels compared to the automatic 4WD mode.

Engines

4007 is launched with a latest-generation HDi Diesel engine derived from a co-operation between the PSA Peugeot Citroën and the Ford Motor Company.

With a capacity of 2.2-litres, the engine develops a maximum power of 115 kW at 4000 rpm, or around 156bhp CEE. This is a single-turbo version of the 2.2-litre HDi 125 kW engine, but with variable geometry, and was recently introduced in the 407 and 607 ranges.

To ensure a high level of driveability and exploit to the full the maximum torque of 380 Nm available from low engine speeds (2000 rpm), a 6-speed manual gearbox manufactured by 'Aisin' is coupled with the engine.

This power unit is characterised by a high level of verve and dynamic performance which is approaching that of modern Peugeot hatchbacks in the upper middle segment. Handling characteristics set the 4007 apart from its direct competitors, namely other compact SUVs.

The engine is equipped with the latest-generation Diesel Particulate Filter System (DPFS). Due to its electronic management and the use of an additive to reduce the 'particle' combustion temperature, as well as the 'octosquare' filter element shape, the filter's service interval has been extended to 180,000 km. This reinforces Peugeot's environmental credentials as one of the leading manufacturers in the clean technology stakes and most specifically where the elimination of diesel particle emissions is important.

Safety

In addition to the four-wheel drive and strong body structure, 4007 benefits from the latest technologies to protect its occupants in the event of impact and avoid driving hazards. ESP (Electronic Stability Programme) is a standardfit feature on the 4007. This system enhances the vehicle's stability by controlling the braking and engine power applied to individual wheels. The electronic system helps to keep the vehicle on the trajectory required by the driver, by controlling oversteer and correcting understeer during vigorous use of the steering wheel or under precarious road conditions.

It should be emphasised that compared to a classic hatchback, the 4WD transmission, coupled with the ESP system, also controls torque transmitted to the rear wheels, thereby increasing the efficiency of the stability control system. In addition, as well as ABS, the vehicle incorporates a traction control system which monitors traction and improves engine performance and vehicle behaviour during acceleration in curves or on a gradient.

In terms of passive safety, the 4007 is equipped with six airbags: two front airbags, two side airbags and two curtain airbags.

The adaptive front airbags inflate to two levels according to the severity of the impact. The passenger air bag can be switched off by means of the ignition key switch located in the glove box to allow for the installation of a rear-facing child seat. An indicator on the fascia panel reminds occupants if the airbag has been switched off.

The side airbags are housed in the back of the front seats. In the event of a side impact they protect the chest and upper part of the body. The curtain airbags also protect the heads of the passengers in rows one and two in the event of side impact.

For child safety, the 4007 offers Isofix mounting points in all three row-two seats. To alert the driver that a seat belt has been unfastened while driving, an audible signal is emitted together with a message on the instrument panel.

The enlarged field of vision combined with the raised driving position, a characteristic of SUVs, means the driver will feel safer when driving in traffic. Passengers also benefit from this raised position and from the panoramic view by the large glazed surface area of the 4007.

Modularity and versatility

The 4007 can accommodate up to seven people, thanks to a third row of seats which retracts into the floor of the boot. These two cleverly designed additional seats can be manipulated easily by means of three straps: one for unlocking, one for deployment and one for folding. Occasional passengers occupying the retractable bench seat benefit from head restraints and seat belts with inertia reels just like the other occupants.

The row-two seats split 40/60 and can slide over a distance of 80mm. Additional to these functions is the possibility of folding the entire bench seat in a concertina fashion by means of an automatic device. Two switches located on the right-hand and left-hand sides of the boot allow electrical unlocking of the bench seat, which then folds double by the action of springs. It is also possible to fold one section of the bench seat manually by means of two knobs located on ether side of the seats.

This allows access to the two retractable seats and can free up additional load volume. Thanks to these modular configurations, the boot offers exceptional load volumes. With row-two fully retracted, the load volume up to the roof is 1686 dm3 (VDA standard). In a more conventional configuration, with the second row in place, the volume under the parcel shelf is 463 dm3. This can be increased to 510 dm3 with the bench seat as far forward as possible, due to its slide system. With seven people in the car, the boot volume to the level of the row-three seat backs is still 184 dm3.

The boot, easily accessible because of the split opening tailgate, is easy to load. The lower part of the tailgate can take a load of 200 kg. Due to the flat floor and the absence of a load sill, heavy objects laid on the lower tailgate are easy to slide inside the boot.

A removable and adjustable flexible roller-blind can be used to conceal the boot's contents.

Highly modular and cleverly designed, the interior of the 4007 is therefore ideal for versatile use.

Clever numerous storage spaces

Maximising the interior space of 4007 is demonstrated by the many storage spaces available.

Two glove boxes are available in the upper and lower part of the fascia panel. The lower glove box can be locked with the key, while the upper one is refrigerated.

There is a small closed storage space at the top of the centre console, while a swivel storage unit in the roof can hold a pair of glasses. Behind the courtesy light, a recess can accommodate a car park ticket or toll ticket and cup holders are accessible on the driver's side and between the front seats. The door panels house a large storage area in the lower section able to hold a halflitre bottle.

The central front armrest, adjustable over a length of 65mm, opens in two parts. The lower part, which has a 12 volt connector, can contain up to 10 CDs. The upper part lets occupants keep small objects such as mobile phones within arm's reach and the rear central armrest also incorporates two cup holders.

In car comfort

Particular attention has been paid to acoustic comfort, particularly in terms of engine noise insulation, ensuring a high level of comfort for this vehicle range and engine type.

From the point of view of temperature, passengers in the 4007 benefit from automatic air conditioning equipped with a pollen and dust filter, which guarantees a regulated interior temperature between 18° and 32 °C.

Multimedia equipment

With a view to comfort and convenience, the latest-generation of audio and telematic equipment is available. According to market versions, 4007 is specified with a single-CD / radio / MP3 player, or a radio / MP3 player with 6-disc CD Autochanger. In all cases, 6 speakers with a total power of 140W to provide clear sound entertainment.

Available as an option in some markets, it is possible to choose a high-performance 'Rockford Fosgate' Hi-Fi system with a maximum output of 650W. For perfect reproduction of high fidelity sound, eight speakers are distributed in the passenger compartment accompanied by a bass cabinet in the boot. This unit incorporates absorbent materials designed to reduce vibration and any audible interference liable to diminish sound quality.

A colour satellite navigation system with 7" touch screen is also available as an option. The integral 30GB hard disk contains cartography for Europe (NAVTEQ), leaving 10GB free to store around 2500 tracks in MP3 or WMA formats.

Further equipment, like Bluetooth hands-free kit, a DVD player incorporated in the position of the courtesy light with a retractable 9" screen, or a sunroof can supplement the 4007s standard specification.
