Particular attention has been paid to the key Peugeot values of road holding and driving pleasure, to create a vehicle which will become the reference in the segment, both in terms of driving dynamics and its uncompromising active and passive safety.
The 207 benefits from an excellent body torsional rigidity of 0.8 mrd / 100 mdaN which, through the effectiveness of the suspension guarantees both active safety and driving pleasure. The suspension, features numerous developments compared to that of the standard platform vehicle, to ensure the dynamic performance, is characterised by its balance between road holding and comfort.
The widening of the front and rear tracks allows the rigidity of the body to provide greater stability in many different dynamic situations. The McPherson type front suspension has been redesigned to increase the caster angle and improve the steering action and accuracy.
Other key changes include new wishbones that improve rigidity and steering response, increased anti-roll bar control, and a sub-frame that incorporates a new deformable impact structure with a lower pedestrian impact beam. The rear suspension with a deformable cross member is entirely new to ensure the dynamic objectives of the 207 can be achieved and to accommodate the physical characteristics of the design.
It is characterised by its compact design which saves weight, but also by the increased rigidity for better vibration and body control. The fitment of vertically mounted shock absorbers and larger flexible mountings ensures a good compromise between driving pleasure, passive safety and vibration/noise suppression. Designed and manufactured in-house, the hydraulic shock absorbers use active valve technology to ensure both comfort and optimal road holding.
Optimised «brushless» electric power steering enhances the 207’s versatility both in town and on the open road. This technology makes it possible to modulate the power steering continuously and independently of engine speed, ensuring a smoother transition from high assistance at low speed to reduced assistance at high speed.
It also makes it possible to improve centring around the straight ahead or «zero position» thanks to its low response time and optimised electronic management. Manoeuvrability is enhanced by a turning circle between kerbs of between 10.40 m and 10.60 m, depending on version.
Braking has been refined in terms of stopping distance, durability and brake pedal feel. In this respect, all 207s have large brake calipers at the front matched with ventilated discs with a diameter ranging from 266 to 283 mm.
Depending on version, the rear brakes are either 9’’ drums or 249 mm solid brake discs.In addition, all 207s are equipped with an ABS system that prevents wheel lock up, as well as electronic brake force distribution (EBFD), which allows the full braking potential to be used by delivering the maximum possible braking force to each wheel.
Emergency braking assistance (EBA) and automatic illumination of hazard warning lights in the event of sharp deceleration are additional standard features. The latest-generation ESP (Electronic Stability Program) is available as an option or as standard depending on version. This includes traction control (ASR) acting on the engine management and on the brakes, and stability control (CDS) which, by means of a steering wheel angle sensor, yaw speed sensor and lateral acceleration sensor, can detect any incipient under or oversteer. The ESP can be de-activated to improve traction when driving away on slippery surfaces but, automatically re-activates once the vehicle reaches a speed of 50 km/h.
Driving aids A lot of attention has been paid to provide driving aids which add to the comfort and peace of mind of the driver, and thereby ensuring their safety and that of all passengers in the 207.
Speed limiter To make driving as stress-free as possible and to help the driver observe speed limits, a variable speed limiter coupled with a cruise control function is available as standard or as an option. A control stalk mounted on the steering column makes it possible, at the touch of a button, to activate or de-activate the functions and determine the reference speed without the driver needing to remove their hands from the steering wheel. All information data is displayed on the instrument panel.
Tyre surveillance An under-inflation tyre detection system is available as standard or as an option according to version. The tyre detection sensor identifies any loss of pressure or a puncture and sends the information to the multifunction display. Location of the defective tyre is also indicated on the screen, coupled with the illumination of a pictogram in the instrument panel and an audible warning.
Parking assistance The 207 can be equipped with a particularly sophisticated rear parking assistance system developed from the system fitted to higher segment vehicles. The remaining distance is indicated by an audible signal and displayed on the multifunction display in the form of bars (monochrome screen) or coloured zones (colour screen). The driver can if required de-activate the audible signal and keep only the visual assistance if preferred
Accessibility of controls The driver has access to numerous functions with a minimum of fuss. All 207s benefit from electric windows at the front with control switches mounted on the door panels. The driver’s window incorporates a one-touch safety auto-reverse operation.
Remote controls under the steering wheel duplicate the controls of the radio. If the car is equipped with the Bluetooth phone kit, drivers can also safely operate their «Bluetooth» mobile phones, hands-free. They also provide access to the RT3 telematics system and its services. Lighting The large headlamps with their complex reflector surface and dual lights (H1 + H7) deliver a high-quality, high-performance beam of light, even in bad weather. On some versions, the use of an H7 elliptical module combined with static directional lighting enhances still further the 207’s high-tech lighting. This technology, rare at this segment level, makes it easier to identify a pedestrian about to cross the road or a cyclist, when making a turn in urban traffic.
Static directional lighting consists of two additional H7 headlights located in the main headlamps; illuminate the inside of a corner over an angle of 30°. They are activated individually by an electronic control unit (ECU) which anticipates the need for «side lighting» of the oncoming road. This additional lighting is combined with the main beam or dipped beam when the steering wheel angle sensor registers an angle of between 25° and 50° depending on vehicle speed. Activation of the indicators triggers the directional lighting independently of vehicle speed as soon as the steering wheel angle reaches 20°, projecting a beam of light onto the inside of the bend and the approaches to junctions, even while waiting at a Stop sign. The low height of the «pencil» light beam prevents any glare to oncoming traffic.
The steering column control stalk which controls the operation of the lights has a special position which allows the activation or deactivation of the automatic illumination of the headlight dipped beam, present on many versions, even whilst driving.
An optical sensor located at the base of the interior rear-view mirror identifies variations in the exterior light levels and controls the automatic activation and de-activation of the headlights. This light sensor is coupled with a rain sensor so that when it rains for example, the front windscreen wipers and the headlamps are automatically activated at the same time.
Clear visibility in all weathers
At the front, the 207 is equipped with flat rubber blades with a metallic core. The low park position at the base of the windscreen makes them particularly discreet. A special position enables them to be raised when necessary. When automatic windscreen wipers are fitted, a new 4-position switch is also fitted which includes an «intermittent» and automatic position, to take into account possible variations in the intensity of the rain. For enhanced rear visibility, the rear windscreen wiper is linked to reverse gear and is activated automatically when the front windscreen wipers are operating. Enhanced rear visibility The door mirrors have a large mirrored surface area ensuring excellent vision. They enhance safety when overtaking and during parking manoeuvres. On some versions, they can be folded electrically either by means of the remote control plip, or manually by means of a dedicated switch incorporated in the electric window control panel. The electro-chrome interior rear-view mirror adapts automatically to ambient light levels, avoiding glare caused by following vehicles when driving at night. This function is activated by means of a push-button switch; a green LED indicates that the unit is on standby.
The electro-chrome rear-view mirror itself consists of two thin layers of glass (1.6 mm) between which a gel is deployed in a few hundredths of a second by means of electrolysis. It is controlled by sensors (cadmium-free) which continuously compare the previous and subsequent light level. This equipment, rarely found at this segment level and available as standard or as an option on some versions, enhances the comfort, safety and status of the 207.
In addition, the 207 is one of the very first vehicles to comply with regulations outlined in the new European directive concerning pedestrian impact.
An optimised structure
The structural design of the 207 has been designed to withstand impact levels even more severe than those applied in regulatory tests.
The 207 borrows from the 407 the use of two impact absorption structures, which absorb and distribute impact energy more efficiently in the event of a collision and also enhance repairability and pedestrian impact protection. This technology is not normally found in B segment vehicles.
For front impact.... The engine compartment incorporates an additional impact absorption structure – the lower structure – which supplements the traditional upper structure consisting of the chassis legs. Two thirds of the impact energy is absorbed through the upper structure and one third through the lower structure.
This lower structure is created by the use of an extended front sub-frame consisting of a standard sub-frame with added extensions, a front cross member, impact absorbers and a pedestrian impact beam equipped with integral impact absorbers.
In addition, the upper structure and lower structure are interconnected to optimise the rigidity and stability of the assembly.
This front structure sets a new standard in impact absorption strategy. It enhances energy distribution and ensures the car is sufficiently rigid to ensure protection against high-speed frontal impacts, but also supple enough to afford protection to pedestrians, and compatibility in the event of an impact with a lighter vehicle.
In addition, stiffeners connect the rear of the chassis legs to the tops of the ‘A’ post, thereby reducing the degree to which the chassis legs retract into the passenger compartment. An impactor – a device securing the power train to the front sub-frame – limits its intrusion into the passenger compartment, and the fitment of a steering column that retracts over a distance of 70 mm, completes the impact protection specification.
On left-hand drive vehicles, in the event of an impact, the driver’s «active» footrest pushes the ankle back, thereby reducing the angle of movement and helping prevent serious injury. Similarly, the front passenger’s feet rest on a flat surface, the angle of which has been specially determined to limit the consequences of possible sudden movement.
For side impact ... Protection against a side impact is assured by the design of the body side frame and the superstructure, which absorbs the impact energy and preserves a survival cell for the occupants.
The doors, equipped with a reinforced box section below the window aperture and tubular bracing bars at the bottom of the door structure. This ensures the structural rigidity by creating a solid barrier between the ‘A’ and ‘B/C’ posts and the rear wheel arch.Impact absorption padding is also fitted inside the doors.
In addition, 3-door versions are equipped with a retention pin which locates in a «socket» on the rear of the door aperture, ensuring a «physical link» between the door and the B/C post when the door is closed, helping to guarantee optimal strength of the vehicle structure.
Efficient means of restraint ...
Air bags Two adaptive front air bags with a dual-generator function that can adapt the airbag pressure to the severity of an impact. The driver’s side air bag has a capacity of 60 litres and the passenger side air bag a capacity of 90 litres.
The passenger air bag can be de-activated by means of an ignition key operated switch in the glove box, allowing the installation of a rear-facing child seat. Two side air bags each with a volume of 11 litres, located in the sides of the front seats, protect the chest, abdomen and pelvis of the front occupants.
Two curtain air bags each with a volume of 23 litres located along the roof arch and «working» in conjunction with front chest side air bags. Their central positioning helps to protect the chest and upper body of the front and rear passengers. They are available as standard or as an option according to version and destination. Seat belts Five 3-point inertia reel seat belts are fitted: At the front, two height-adjustable pre-tensioning inertia reel seat belts with force limiters set at 450 daN. At the rear, two outer inertia reel seat belts with force limiters set at 600 daN and one inertia reel seat belt integrated into the centre seat back to make it easier to locate and therefore provide a greater incentive to use it.
The effectiveness of the rear seat belts is also improved by the design of the rear seat base, which has a special «raised» profile that affords greater stability to the rear passengers. It also prevents the rear passengers from being subjected to the «submarining» effect, which can occur in the event of an impact.
Audible and visual fasten seat belt warnings are fitted on all 207s (fastening of the driver’s seat belt only on the entry level 207). A dedicated information screen indicates if the seat belts are fastened or not, through the display of red or green pictograms. Child Isofix seat fixtures All 207s are equipped with two 3-point Isofix mountings on the rear outer seats, each of which can accommodate a child’s Isofix car safety seat. The seat belts of the passenger seats are, however, long enough to accommodate a traditional child seat, both at the front and in all three rear seats.
Pedestrian safety The safety of pedestrians was taken into account during the earliest stages of the design of the 207, to ensure its compliance with the new European directive. This forward thinking means that the 207 is one of the first vehicles to comply with the new regulations. The design of the two front impact absorption structures in the engine compartment helps to reduce injuries to pedestrians in the event of a collision. The absorbent padding on the upper impact beam provides protection to the lower limbs of a pedestrian. While a composite pedestrian impact beam with integral impact absorbers is positioned as the final element of the lower structure and designed to push the pedestrian’s leg aside to avoid serious knee injuries.
The underside of the bonnet has also been designed to provide the maximum possible space between the underside of the bonnet and the «hard» components of the engine bay. This space creates a «survival zone» which provides a protective barrier, protecting the head and body of a pedestrian, as any impact can be absorbed over a large surface area without contact with any of the «hard» mechanical components underneath. Lastly, the headlights are equipped with «fuseable» mountings that «direct» the headlamps to move backwards under the bonnet in the event of an impact.
The «survival zone» combined with the programmed «flexibility» of the headlamp mountings means that the front structure of the 207 can absorb a high percentage of impact energy, thereby reducing injuries to pedestrians. Locking and surveillance Locking and security systems contribute to the safety of the 207 and protect the car against intrusion, and include:
automatic drive away locking of the doors and the boot as soon as the car reaches a speed of 10 km/h (can also be activated manually),
an interior and perimeter alarm available as an option, combined with deadlocking of doors and electric rear child safety locks,
high security locks,
locking wheel bolts when alloy wheels are fitted,
three individual vehicle identification number (VIN) markings.
Materials and recycling
Peugeot’s concern for the environment has been reflected in the design of the 207, careful consideration has been given to the impact of its components on the environment, and the ease of recycling was a key priority.
Five major categories make up 98 % of the 207’s weight:
metals 69 %
plastics 17 %
fluids 5 %
rubber 4 %
glass 3 %
This allows a rate of recycle-ability of 85.2 % and a rate of material recycling approaching 96 %. To make it easier to clean up vehicles at the end of their useful life, the low points of the different reservoirs are all marked.
Electronic units (particularly those triggered by an explosive device) are easy to de-activate to ensure the safety of personnel responsible for processing scrap vehicles. Disassembly manuals have been produced for use by breakers to optimise the recycling of materials.
All plastic and rubber parts are marked precisely to facilitate sorting by category, with multiple markings on larger components to avoid loss of information. Finally, the use of recycled materials in the creation of certain non-visible parts has been applied wherever possible.
