            C4 na Mondialu 2004 virCP

            CITROËN C4
            A SALOON, A COUPÉ

            Citroën is premiering the C4 – its new mid-range offering – at the 2004 Paris Motor Show. The C4 is available in saloon and coupé form: two vehicles of innovative styling and features.


            The C4 Saloon and the C4 Coupé each have their own distinctive style. However, they share the same generous interior space, contributing to the comfort of the passenger compartment.
            The saloon has rounded forms, while the coupé favours a sharper line. Both vehicles share smooth, fluid lines for outstanding aerodynamics, one of Citroën’s traditional strengths (Cd of 0.28 for the coupé and 0.29 for the saloon). The two vehicles also share the same interior space. Passengers at the rear enjoy a generous level of knee room, which is among the best in the segment (17 cm when the front seat is pushed back to the maximum).


            The on-board comfort of the C4 is enhanced by innovative functions designed for easy, relaxed driving.
            For example, the multifunctional fixed-centred controls steering wheel brings the main comfort functions and driving aids within easy reach. This ergonomic feature, which places the emphasis on easy-to-use controls, promotes driving pleasure.
            The steering wheel is associated with a translucent instrument cluster of new design, which displays driving information (vehicle speed, speed limiter and cruise control settings, etc.) on a translucent strip in the centre of the dashboard. The display contrast adjusts instantly to ambient light conditions to ensure a clear read-out at all times.
            The C4 also features a wide array of modern and efficient driving aids. The lane departure warning system is a major step forward in driving safety. At speeds of over 80 kph, this system warns the driver if the car crosses a continuous or broken lane marking, if the indicator has not been activated.
            The C4 introduces a range of equipment usually found only further up the market, including Xenon dual-function directional headlamps and front parking assistance. A speed limiter and low tyre-pressure detection – two features rarely seen in this segment – are also available.
            All these advanced functions create a relaxed atmosphere in the passenger compartment, further enhanced by the scented air freshener styled to match the interior, and the laminated side windows for acoustic comfort. In terms of practical features, the C4 features a host of stowage compartments including a boot foldaway partition to hold objects firmly in place.
            On-board comfort also means relaxed driving in all circumstances. With its advanced equipment and features, the C4 offers high-level active and passive safety, along with polished road manners.
            In particular, the C4 boasts the world’s first shape-optimised driver airbag. This feature, which relies on the fixed central section of the steering wheel, improves driver protection. Also, its design reflects efforts to protect pedestrians more effectively in the event of frontal impact.


            The C4 is available with a wide range of engines from launch. It offers a choice of five petrol engines: the 1.4i 16V (90 bhp DIN), the 1.6i 16V (110 bhp DIN), the 2.0i 16V (138 bhp DIN), the new 2.0i 16V (143 bhp DIN) recently introduced on the C5 and available with the C4 Saloon and the 2.0i 16V (180 bhp DIN), installed on a Citroën vehicle – the C4 Coupé – for the first time. The C4’s three HDi diesel engines are all equipped with second-generation common-rail. The HDi 92 is making its debut on a PSA Peugeot Citroën Group vehicle, while the new HDi 110 and HDi 138 engines were recently introduced in the Citroën range.
            Most of these engines already satisfy the Euro IV emission standard. With the C4, Citroën is also expanding the range of vehicles equipped with the diesel particulate filter system (DPFS). This technology adds to the advantages of HDi engines in terms of environmental protection.
            The C4 reflects Citroën commitment to bringing customers innovative and appealing cars.
            By offering saloon and coupé versions, Citroën is pursuing a strategy initiated in the supermini segment, where it has three complementary offers (C2, C3 et C3 Pluriel), each with distinctive styling to address wide-ranging customer tastes.


            The Citroën C4 is available as both a saloon and a coupé.
            Boasting distinctive styling, each in its own register, these two vehicles are intended for customers of differing requirements.


            The C4 Saloon and the C4 Coupé have very different styling, while also sharing a number of features that identify them as members of the same family.
            The style of the C4 is characterised by decisive architectural choices. Its height is limited in order to optimise aerodynamics, road behaviour and fuel consumption. In consequence, power and fluid design lines emerge as the key traits qualifying the C4.
            However, the real signature of the C4 can be read in its strong exterior features, some of which are common to both the saloon and the coupé.
            These distinctive signs can be seen on the front end in particular, with the chrome chevrons spanning the full width of the radiator grille, and the boomerang-shaped lights extending up to the vehicle wings. Other distinctive features include the flag-shaped rearview mirrors on the front doors, which give prominence to the sides of the C4.
            Looking beyond these shared attributes, Citroën is offering two clearly differentiated body styles :
            • a saloon of fluid, dynamic lines with strong curves
            • a coupé of longer, sharper lines with a plunging tail line.

            In both cases: smoothly flowing contours with an ever-present emphasis on aerodynamics.


            The C4 Saloon boasts smooth, protective bodywork, with unique exterior styling. Its profile is traced in a single line, with a strongly raked windscreen that extends the taut lines of the bonnet, before moving smoothly on to the curve of the roof.
            Similarly, the high, arched waist line reinforces the feeling of safety and protection enjoyed by the passengers.
            The harmonious design is combined with a long window line, which draws out the cabin and enhances the fluid lines of the saloon.
            The body style of the C4 Saloon shows distinctive lines of force, which underline its dynamic character. In addition to the headlamps placed either side of the double chevron on the radiator grille, other particularly striking styling features include:
            • rear lights whose geometric shape expresses dynamic power. The lower part underlines the vehicle’s stability, while the upper part runs along the rear window up to the lip at the top of the tailgate,
            • quarter windows and a waist line suggesting controlled power.


            The exterior styling of the C4 Coupé owes its force to its dynamic and fluid body lines, combining a long wheelbase and long front overhang with a short rear overhang.
            The coupé’s profile reflects the quest for optimised aerodynamics. The receding lines converging towards the rear of the vehicle suggest movement and fluidity. The waist line – slightly curved towards the rear – and the prominent wings, suggest stability and good roadholding.
            The tight lines of the roof flowing towards the rear end with a sharply falling rear window offer a perfect fit between the geometric shape of the rear lights and the fluid lines of the coupé.
            The C4 Coupé possesses a distinctive style, with a flowing, easily recognisable profile, and a reverse-sloping rear window with an astonishingly spacious passenger compartment. Its styling combines sportiness and interior space.


            The C4 was designed to meet stringent aerodynamic targets, while also offering class-leading space at front and rear.


            Easily identifiable as Citroën vehicles through their design lines and proportions, the C4 Saloon and C4 Coupé also embody one of the Marque’s traditional strengths: aerodynamics.
            Extensive aerodynamic studies were conducted on the C4 in order to obtain a drag coefficient of up to 0.28 for the coupé, a record in this segment. The saloon boasts a Cd of up to 0.29.
            These values promise acoustic comfort, along with reduced fuel consumption and lower pollutant emissions.

            They are achieved by:
            The exceptionally fluid body styles featuring:
            • limited height (1.46 m),
            • a windscreen placed well to the front, continuing the line of the bonnet,
            • a long roof with a dramatic drop at the rear,
            • sides narrowing at the rear.

            The presence of exterior features designed to smooth air flow:
            • flag-shaped exterior rearview mirrors,
            • aerodynamic undertrays to smooth out the airflow under the body,
            • a rear spoiler extending the flow-line of the roof to the maximum extent,
            • bumpers designed to improve the air flow over the wheels,
            • front windscreen wipers integrated in the scuttle aperture to avoid disrupting the air flow.


            In both saloon and coupé form, the C4 combines style and aerodynamics with a level of interior space that ranks it among the best in its segment.

            Identical interior space on the saloon and the coupé

            Although the C4 Saloon and the C4 Coupé are very different in terms of styling, they share the same interior space.
            They have the same dimensions, viewed from the side, with a wheel base of 2.61 m and a height of 1.46 m. Only their length differs slightly (by 1.3 cm) owing to the style of the rear bumper.
            Generous interior dimensions

            The interior dimensions of both vehicles meet customer requirements concerning the essentials of on-board comfort.
            The two C4s are references in their segment concerning knee room
            for passengers at the rear (17 cm when the front seat is pushed
            back to maximum).
            In terms of elbow room at the front (1.44 m) and rear (1.43 m), the C4 is on a par with most of its competitors in this segment.


            The interior of the C4 boasts a host of innovations in driving ergonomics, life on-board and functional convenience. In addition, the C4 is also available with an array of high-tech communication equipment.


            The C4 features a dashboard of clean design lines with a fixed-centred controls steering wheel that places driving aids within easy reach of the driver. At the same time, some of the instruments are positioned in the centre of the dashboard so that the passengers can contribute to the ride. With the C4, onboard comfort means safety and well-being.

            The multifunctional fixed-centred controls steering wheel

            The fixed centre of the steering wheel features the main comfort functions and driving aids. This layout places the emphasis on ergonomics and easy use, thus promoting driving pleasure.
            • A balanced distribution of controls

            The steering wheel controls are split into four different areas, each with four buttons and a knob:
            • the top right-hand area groups the radio controls, with volume and station settings, the memorised station search function, and the mute function;
            • the bottom right-hand area provides access to the multifunction screen, with — in particular — the on-board computer and the NaviDrive navigation system;
            • the top left-hand area is dedicated to the speed limiter and cruise control. If the driver opts for one of these driving aids, a pictogram will appear on the translucent instrument cluster, showing the mode selected and the programmed speed;
            • the bottom left-hand area groups the controls for vehicle options. For example, the voice control of the NaviDrive navigation system, the telephone controls, the driver-configured button offering “black panel” lighting as the default function, or the air recycling function.

            The horn is on the lower part of the steering wheel.
            Conventional driving functions (lighting and wiping) maintain their usual layout, with standard stalk switches.
            • Driver-dedicated steering-wheel display

            Driving information intended specifically for the driver is displayed immediately in front of him. This is the case, for example, of the rev counter, the indicator and headlamp settings, and the mode/gear speed selected on versions equipped with an automatic gearbox.
            The background of the rev counter turns red to show that the engine has reached its maximum speed.
            Fitted on the steering column, this display unit moves with the steering wheel to remain easily legible at all times.

            • A host of advantages

            The multifunctional fixed-centred controls steering wheel offers the following advantages:
            • controls are grouped in the centre of the steering wheel, thus freeing up space on the dashboard, and giving it a simpler, uncluttered look;
            • significant improvements in ergonomics, since the controls are grouped in a stable and easily accessible position, so that the driver does not have to take his hands off the wheel;
            • as the controls are on the steering wheel, they remain easily visible, even at night, thanks to the use of illuminated pictograms;
            • in terms of safety, the fixed-centre design of the steering wheel makes it possible to install a shape-optimised driver airbag for improved driver protection.

            • Easy operation

            The main characteristic of the C4 steering wheel is its fixed hub. The centre of the wheel no longer turns with the rim. The technical principle is simple: a toothed ring linked to the steering wheel engages an inner pinion, itself linked to the steering column. The space between the ring and the pinion is used to couple the fixed components: the steering wheel hub and the steering column mounting.

            A dashboard designed to promote relaxed driving and shared information

            The clean, soft lines of the dashboard create an uncluttered look that is relaxing on the eye. Enhancing this effect, curves and relief are kept to a minimum. The choice of colours and materials reflects the same approach to design.
            The dashboard is designed to share information, in the same way as on a people-carrier. The centre features three display units:
            • a translucent instrument cluster,
            • a multifunction screen with the on-board computer and NaviDrive navigation system,
            • an air-conditioning display unit for vehicles equipped with automatic air conditioning.

            The central translucent instrument cluster

            The instrument cluster displays information on a translucent strip located in the centre of the dashboard.

            • Clear information

            The translucent instrument cluster provides the following information:
            • vehicle speed,
            • petrol gauge and range,
            • water temperature
            • total and partial mileage,
            • information on the oil level,
            • speed settings for the cruise control and speed limiter,
            • maintenance indicator.

            Indicators corresponding to the child safety function, the seatbelt warning lights for the five seats, and ESP disablement are displayed on either side of the translucent instrument cluster.

            • Perfect legibility

            As the instrument cluster is located in the centre of the dashboard, the translucent strip captures the light perfectly. As the display contrast adjusts instantly to the light, legibility is perfect in all circumstances, by day and night, in full sunlight or in darkness.

            LIFE ON BOARD

            The cabin of the C4 is designed to optimise passenger comfort. The cabin layout, the ergonomics and characteristics of the seats and the soundproofing – essential vehicle qualities – have all been addressed in such a way as to create a relaxing interior ambience.
            In addition, the C4 features a range of equipment to create a feel-good ambience, such as the glazed panoramic roof and the scented air freshener.

            The scented air freshener

            A scented air freshener, styled to match the dashboard design, also contributes to the relaxed onboard atmosphere.

            • A choice of nine fragrances

            The air freshener is available with a choice of nine fragrances: Citrus and Passion, Amber and Sandalwood, Cinnamon and Ginger, Lotus flower, Vanilla, Jasmin and Mimosa, Soft Lavander, Mint and Musk, Ylang and Bamboo.
            All these fragrances were developed by Robertet, a company specialising in the creation of perfumes.
            Customers will receive a kit with three fragrances (Vanilla, Mint and Musk, Ylang and Bamboo) on delivery of their car.

            • A fully integrated system

            Placed on the central air vent, the scented air freshener diffuses the fragrance selected through the air conditioning system. A knob lets the user switch the system off or adjust the quantity of perfumed air.
            The perfumes come in the form of sealed, individual cartridges, so the fragrance can be changed at any time.
            A cartridge lasts around 45 days, based on three hours of daily use.
            Refills are available from the Citroën network.

            Seats tailored to a full range of tastes and body shapes

            Looking beyond their styling, which is an explicit statement of their qualities, the seats of the C4 are designed to ensure an outstanding level of comfort as well as excellent support.

            • Firm support, adapted to everybody’s tastes

            To reflect customers’ tastes more effectively, the C4 is equipped with “comfort” or “vitality” seats, depending on the trim level selected.
            “Comfort” seating ensures excellent damping and also provides sufficient support to hold the occupant firmly in place without becoming restrictive. Placing the emphasis on comfort in use, it is perfect for smooth, relaxed driving.
            “Vitality” seating is firmer to the touch with more pronounced support. It corresponds to the pursuit of stronger driving sensations and a more dynamic driving style.

            • Pertinent settings

            In addition to the conventional seat settings (fore-and-aft adjustment, angle of back rest), the C4 also includes a number of other settings to ensure that all the occupants can find a position to suit their body shape and driving habits:
            • steering wheel adjustable for height and reach,
            • a driver’s seat adjuster that can be raised over 50 mm,
            • manual lumbar adjustment on the driver’s seat.

            The C4 can also be equipped with an electrically controlled driver’s seat. In this case, the settings of the seats and exterior rearview mirrors can be memorised to enable different drivers to immediately find their preferred settings.

            Focus on acoustic comfort

            To optimise acoustic comfort on board the C4, extensive studies were conducted on sealing, and sources of wind noise.
            The main factors contributing to sound insulation are:
            • the flag-shaped exterior rearview mirrors,
            • the laminated windscreen with a damping film between two sheets of glass,
            • the thick glass used for the side windows (3.82 mm instead of the 3 mm usually found on vehicles in this segment),
            • the windscreen wipers integrated with the scuttle aperture,
            • the anti-turbulence windscreen seal,
            • the double door seals,
            • the treating and filling of box sections.

            Available as an option, the laminated side windows reinforce the filtering of wind noise and external nuisances.

            Individual thermal comfort

            To satisfy requests for individual comfort functions at the front, the C4 features automatic two-zone air conditioning. The driver and front passenger can then choose their own temperature settings.
            The automatic air conditioning system is equipped with:
            • a particulate and pollutant gas filter,
            • an air recycling function, activated using controls on the steering wheel and air conditioning panel,
            • a heat-reflecting windscreen, which considerably increases the reflection of infrared rays.


            With its many stowage compartments, easily adaptable, modular passenger compartment and boot foldaway partition, the C4 is an easygoing car that adapts to the requirements and needs of the moment.

            A host of practical and well designed stowage compartments

            From the dashboard to the consoles and door panels, the interior of the C4 possesses generous stowage, including: a vast glove box, bins in the doors, can-holders, a drawer under the front passenger seat and nets on the backs of the front seats.
            Evenly distributed around the passenger compartment, these stowage compartments were designed for practical use. The closed stowage compartments have a damped opening, the drawers are of the push/pull type and the ash tray is illuminated, as is the glovebox, which may also be cooled. Some stowage compartments are even intended for specific purposes, such as the bag hook on the passenger side of the central console or the overhead eyewear holder on the driver’s side.
            A number of stowage compartments are closed in order to maintain the ambient, uncluttered atmosphere. For example, the front central armrest, with fore-and-aft adjustment, has a stowage compartment for CDs or the CD stacker. The console is also equipped with a 12V socket and a cigarette lighter.
            Easy modularity

            The C4 features a 60/40 split-folding rear seat back and cushions. Simple attachments make it easy to take advantage of the C4’s modular interior.
            The seat backs unlock easily and can be folded down:
            • directly onto the seat cushions,
            • with the seat cushions raised, in order to obtain additional space and a virtually flat load floor,
            • using clips, after the fast-fit seat cushions are removed. In this configuration, the loading space extends up to the front seats.

            A new boot foldaway partition

            The boot of the C4 features a new partitioning system. This system is designed to isolate and securely hold the objects placed in the boot.
            A simple function lets the user fold out the partitions integrated in the boot sill to create three separate compartments.
            When folded, these partitions disappear totally into the thickness of the boot sill. When partitioning is not used, the boot regains its full loading volume.
            The boot of the C4 can also be fitted with a closed stowage bin on the sides, a stowage net and a range of hooks to hang bags up.


            To enhance onboard comfort, the driver can choose from a range of hightech equipment including:
            • the NaviDrive telematics system for stress-free driving,
            • the JBL hi-fi system for high-level acoustics,
            • the Bluetooth hands-free telephone system for safe communication.

            Stress-free driving with NaviDrive

            The C4 is available with the new-generation NaviDrive telematics system.
            It offers a number of essential functions: a GPS navigation system, a GSM dual-band hands-free telephone with access to the address book and audio system (radio and 5-CD stacker). At the same time, passengers can use the screen or voice synthesis function to read the SMS messages received over the phone.
            The main functions can be accessed easily using the steering-wheel controls, which can also be used for the voice recognition and synthesis functions. NaviDrive can be controlled by the user’s voice without any preliminary learning time. This feature is very useful for making phone calls, finding your way, or accessing the address book without risk. The system can also be controlled directly using the unit integrated with the dashboard.
            The functions are displayed on a black-and-white screen or on a large 16:9 colour screen.
            NaviDrive was also designed to offer a number of additional customer services: Citroën Emergency, Citroën Assistance and Citroën On Line.
            Working with the GPS and telephone functions, Citroën Emergency makes it possible to locate the vehicle if the driver has an accident or is ill, for example, and to access the services of a call centre.

            A customised hi-fi function

            JBL, one of the world’s leading audio specialists, has developed a hi-fi system specially for the C4. The new system is designed to offer customised acoustics of superb quality.
            The hi-fi system comprises ten loudspeakers in six locations, together with a subwoofer that is fitted in the boot. The presence of the subwoofer in the boot provides wraparound sound quality and an extremely faithful reproduction of musical material.
            The system is controlled by an amplifier located under the front passenger seat. This unit is parametered with the acoustic settings defined and optimised for the cabin of the C4. Both driver and passengers enjoy excellent sound quality, along with acoustic reproduction that is perfectly adapted to their environment in all circumstances.
            Making telephone calls safely with Bluetooth

            The C4 features a Bluetooth hands-free telephone system in which the address book is displayed on the vehicle’s multifunction screen.
            This hands-free telephone system, based on Bluetooth wireless technology, is integrated with the passenger compartment.
            Bluetooth is a convenient and safe option for making personal in-car calls from a mobile phone, since the driver can make calls without taking the phone out of his pocket. In this way, he can make phone calls from the car without taking his eyes off the road or releasing the wheel.
            To make a hands-free call, the driver uses the ergonomic control function on the wheel, and the microphone built into the roof. Conversations are relayed over the C4’s audio system.
            The driver selects the name of a correspondent from the address book of his mobile phone, using the steering wheel controls. He can also use the “voice recognition” function to initiate a call.
            The phone directory and the name of the correspondent are displayed on the vehicle’s multifunction screen.


            On-board comfort also means enjoyable, relaxed driving in all circumstances. For this reason, in addition to its widerange of new-generation engines, the C4 boasts a range of technological innovations designed to enhance driving comfort and so promote better vehicle control. With its advanced equipment and features, the C4 also offers highlevel active and passive safety, along with exceptionally polished road manners. New technologies have been applied systematically in all these areas, in order to develop new services and functions that provide the driver with more information, while letting him concentrate on the road.


            The C4 driver has access to a range of modern and innovative driving aids which, combined with the interior comfort and uncluttered design of the cabin, let him take to the road with a relaxed mind.

            The lane departure warning system

            The lane departure warning system detects a lane change on a motorway or fast road from speeds of 80 kph. It warns the driver if the car crosses a continuous or dotted lane marking, if the indicator is not activated. A vibrating mechanism mounted in the car seat is activated on the side corresponding to the direction of vehicle drift, enabling the driver – who may have suffered a moment’s distraction – to take corrective action in time.
            Six pairs of infrared sensors located under the front bumper – three on either side – monitor and detect a lane change. Each pair is made up of an infrared emitting diode and a detection cell. The detection function relies on variations in the infrared beam reflected by the diode on the road surface.
            A control unit receives the information and activates a vibration mechanism in the driver’s seat, on the side corresponding to the drift. Alerted by the vibrations on the left- or right-hand side, the driver can then steer the car back on course. This system, which can be activated or deactivated from the dashboard does not disturb the passengers, and leaves the driver free to perform manoeuvres.
            Taking a significant step forward in terms of safety, this innovation is one of the solutions developed to make up for a loss of concentration or a moment’s distraction on the part of the driver.

            Xenon dual-function directional headlamps

            The C4 is also available with a feature that remains rare in this segment: Xenon dualfunction directional headlamps (low beam and high beam).
            When the car takes a corner, the beam lights up the inside of the curve, illuminating areas that were previously in darkness. The beam is angled by up to 15° (8° for the headlamp on the outside of the bend, and up to 15° for the headlamp on the inside). This feature allows the driver to see where he is going and to distinguish other road users and possible obstacles. This is an important advantage in terms of safety since, at a speed of 110 kph, the car covers more than 30 metres every second. When Citroën developed this function for the DS, the controls were mechanical. Today, they rely on electronics.
            This swivelling beam enhances the lighting quality of the Xenon dual-function discharge lamps, which are active in both the low-and high-beam positions.
            By improving driver visibility and reducing visual fatigue, this feature brings significant gains in safety and driving pleasure.

            Front and rear parking assistance

            The C4 brings customers an effective parking aid, with the introduction of front parking assistance, alongside the rear parking assistance function.
            The sensors work in the same way at the front as at the back. Four sensors located in the bumper inform the driver that an obstacle is present in their detection area when vehicle speed is lower than around 10 kph. Depending on the position of the obstacle, the system emits a series of beeps that gradually become more frequent as the car approaches the obstacle, becoming a continuous signal when it is just a few centimetres away.
            The system lets the driver view the distance separating the car from the obstacles at both front and rear. The multifunction screen displays the silhouette of the vehicle, along with six detection areas.
            The parking assistance function can be disabled from the dashboard.

            Cruise control and the speed limiter

            Cruise control and the speed limiter round out the list of new comfort and safety equipment.
            Cruise control lets the driver keep the car going at a programmed speed without using the accelerator pedal.
            With the speed limiter, the driver defines a maximum speed not to be exceeded, whatever the position of his foot on the accelerator. If he wishes to exceed this speed from time to time, he stamps down on the pedal in order to pass the hard spot marking the end-of-travel point of the accelerator.
            For the cruise control and the speed limiter, the driver simply programmes a required speed using the function on the fixed-centred controls steering wheel. A readout on the translucent instrument cluster then shows the programmed speed and the status (active/inactive) of each system.

            The low tyre-pressure warning system
            Already present on the C5 and the C8, the low tyre-pressure warning function enhances the range of safety equipment present on the C4. This system measures the pressure of all four tyres. Each tyre is fitted with an emitter and a pressure sensor, which sends information to the central control unit. When one of the tyres drops below its preset pressure level, a message immediately flashes up on the multifunction screen to warn the driver. At the same time, a buzzer sounds. In the event of a puncture, the “Stop” indicator will also come on. In this way, this feature detects any under-inflation that could have an adverse impact on the car’s stability and on the safety of the occupants.
            In addition to improving safety, this function also encourages the driver to check tyres regularly and to correct inflation levels. These checks bring gains in terms of reduced driving noise, fuel consumption and tyre wear.


            Right from launch, the C4 is available with a wide choice of new-generation engines. The range is organised around five petrol engines, including the new 143 bhp 2.0i recently introduced on the C5, and three HDi diesel engines developed through the cooperation project with Ford. They include the HDi 92 – fitted for the first time on a PSA Peugeot Citroën vehicle – and the new HDi 110 and HDi 138 recently introduced in the Citroën range.
            Most of these engines already satisfy the Euro IV emission standard. With the C4, Citroën is also expanding the range of vehicles equipped with the diesel particulate filter system (DPFS). This technology adds to the advantages of HDi engines in terms of environmental protection.


            Five petrol engines are available: the 1.4i 16V (90 bhp DIN), the 1.6i 16V (110 bhp DIN), the 2.0i 16V (138 bhp DIN), the new 2.0i 16V (143 bhp DIN) recently introduced on the C5 and available with the C4 Saloon, and the 2.0i 16V (180 bhp DIN), installed on a Citroën vehicle – the C4 Coupé – for the first time. All the engines feature a cylinder head with a double overhead camshaft, four valves per cylinder and a motor-driven throttle, controlled electrically by the engine control unit. All the engines are equipped with a five-speed manual gearbox, except for the 143 bhp 2.0i 16V engine, which is coupled with an automatic gearbox. The 110 bhp 1.6i 16V engine is also available with an automatic gearbox.

            The 1.4i 16V engine is the entry-level model. It develops 65 kW EEC (90 bhp DIN) at 5,250 rpm and maximum torque of 133 Nm at 3,250 rpm. It features continuously variable valve timing (VVT) to optimise filling of the combustion chambers at all engine speeds. Variable valve timing offers more torque at low engine speeds. Torque of 118 Nm – 90% of maximum torque – is available from 1,800 rpm, thus contributing to the respect of the Euro IV emission standard. The angular variation with respect to crankshaft timing is managed by the engine control unit, in line with the engine oil temperature, engine load and speed.
            This engine also features a stiffened cylinder block to meet high standards of acoustic comfort. Fuel consumption is low (6.4 l/100 km over a standard combined cycle), and emissions satisfy the future Euro IV standard.

            The 1.6i 16V engine develops 80 kW EEC (110 bhp DIN) at 5,800 rpm and maximum torque of 147 Nm at 4,000 rpm. Highly responsive from the lowest engine speeds, this engine offers torque of 132 Nm –90% of the maximum amount – from 2,000 rpm. This mid-range engine strikes an excellent balance between performance and fuel consumption in combined use (7.1 l/100 km over a standard combined cycle).

            The 2.0i 16V engine develops 100 kW EEC (138 bhp DIN) at 6,000 rpm with torque of 190 Nm at 4,100 rpm. The high engine torque available from low engine speeds ensures a smooth response to driver input. This engine offers torque of 165 Nm from 2,000 rpm, almost 87% of the maximum torque available.
            The power of the engine combined with the strong, steady increase in engine speed make the C4 138 bhp 2.0i 16V a pleasant and relaxing drive, offering superior responsiveness and acoustics.

            The 2.0i 16V engine is also available with the C4 Saloon, in a version offering output of 103 kW EEC (143 bhp DIN) at 6,000 rpm. It is coupled with an automatic gearbox. Recently introduced on the C5, this new version of the 2.0i 16V engine offers maximum torque of 200 Nm at 4,000 rpm. It features continuously variable valve timing (VVT) to optimise filling of the combustion chambers at all engine speeds. This engine offers torque of 170 Nm from 2,000 rpm, almost 85 % of the maximum torque available.
            It also meets the requirements of the Euro IV emission standard.

            The 2.0i 16V engine, developing 130 kW EEC (180 bhp DIN) at 7,000 rpm is the most powerful engine in the range. The C4 Coupé is the first Citroën vehicle to offer this engine. This engine combines dynamic driving thrills with a high level of safety and daily comfort of use. Maximum torque is 202 Nm at 4,750 rpm. On this engine, the intake camshaft is also equipped with a continuously variable valve timing system. This characteristic makes for a powerful, responsive engine.


            The C4’s three HDi engines are all equipped with secondgeneration common-rail. The HDi 92 is making its debut on a PSA Peugeot Citroën Group vehicle, while the new HDi 110 and HDi 138 engines were recently introduced in the Citroën range.
            The characteristics and performance of these compact, lowweight engines are exceptional: driving pleasure, reduced fuel consumption and pollutant emissions are combined with acoustic comfort and vibration control. The engines are also remarkable for their verve, and for the temporary torque increase of 20 Nm made available by the overboost function, which is present on the two most powerful versions.
            The HDi 138 engine is coupled with the six-speed manual gearbox, recently introduced on the C5.

            The new 1.6. HDi 16V engine develops 66 kW EEC (92 bhp DIN) at 4,000 rpm and torque of 215 Nm at 1,750 rpm. Based on the HDi 110, this “all-aluminium” engine is making its debut in the Citroën range. With low fuel consumption (4.7 l/100 km over a standard combined cycle) and CO2 emissions of just 125 g/km, this engine satisfies the Euro IV standard.

            The 1.6 HDi engine is also available in a version offering output of 80 kW EEC (110 bhp) at 4,000 rpm, introduced on the Xsara Picasso in February 2004. It supplies maximum torque of 240 Nm at 1,750 rpm. Torque can be increased to 260 Nm at 1,750 rpm on the three highest gears, thanks to the overboost function.
            For strong bursts of acceleration, the “overboost” function kicks in, delivering up to 20 Nm of additional torque by increasing the fuel injection rate. This new engine therefore combines a fast response with a linear increase in power, and excellent acceleration at low engine speeds.
            The HDi 110 features a second-generation injection system delivering injection pressure of 1,650 bars, controlled by piezoelectric-type injectors. A variable-geometry turbocharger enhances driving pleasure and performance. This engine makes full use of the potential offered by the common-rail system with its multiple injection technology and the enhanced management of fuel injection into each cylinder, providing four injections per engine cycle:
            • two pilot injections to reduce combustion noise
            • two main injections to reduce nitrogen oxide emissions at source.

            Moreover, two additional post-injections improve the regeneration efficiency of the particulate filter.
            As a result of its low fuel consumption – 4.7 l/100 km over a standard combined cycle – and its 60-litre tank, this engine offers a range of more than 1,200 km. CO2 emissions are also very low, at 125 g/km.
            The Euro IV version, available in some countries from the launch of the C4, is equipped with the diesel particulate filter system (DPFS), which traps and destroys particulates.

            The 2.0 HDi engine complies with the Euro IV standard and is coupled with the diesel particulate filter system (DPFS). It develops 100 kW EEC (138 bhp) at 4,000 rpm. Offering maximum torque of 320 Nm at 2,000 rpm, it also features an overboost function that raises torque temporarily to 340 Nm. This new engine is coupled with a six-speed manual gearbox already available with the C5.

            The HDi 138, like the HDi 110, features a second-generation injection system and a variable-geometry turbocharger.


            To keep the car under control at all times, the C4 driver can rely on efficient running gear, along with high-performance braking functions for advanced safety.
            Efficient running gear

            The running gear of the C4 offers precise handling, while also effectively contributing to active safety. The front suspension features a MacPherson type strut with lower wishbones and an anti-roll bar. The rear suspension features a flexible transverse beam associated with an anti-roll bar.
            Damping control is adapted to optimise the balance between comfort and handling.
            Depending on the level of trim and the engine, the C4 is available with 15-inch wheels and 195/65R15 tyres, 16-inch wheels with 205/55R16 tyres, or 17-inch wheels with 205/50R17 tyres.
            Variable-assistance power steering is standard. The level of assistance is linked to engine speed in order to obtain a level of power adapted to conditions of vehicle use. Power steering is firmer at high engine speeds for increased safety, and lighter at low engine speeds for easy manoeuvring.

            High-performance brakes

            The C4’s braking system features ventilated discs at the front and discs at the rear, combined with EBS and electronic brakeforce distribution (EBD).
            To further improve braking safety, the C4 is fitted as standard with emergency braking assistance (EBA) and automatic hazard warning lights.
            ESP (electronic stability programme) is also available with all engines. It is coupled with traction control to prevent skidding.
            This systems can be disconnected with the 180 bhp 2.0i 16V engine.

            The C4 boasts a wide array of passive safety features. It boasts the world’s first shape-optimised driver airbag. This feature, which relies on the fixed central section of the steering wheel, improves driver protection. The C4 also offers reinforced protection in the event of frontal impact, and a design that reflects efforts to address pedestrian impact.
            For increased security, the C4 is also well protected against theft and break-in.
            A complete, reliable range of passive safety equipment
            The C4 offers the following main passive safety features:
            • a shape-optimised driver airbag for improved driver protection;
            • driver and passenger dual-stage front airbags.

            This system adapts to the severity of impact: if impact is minor, only one stage of the airbag will deploy, for high-level protection.
            • curtain airbags standard at front and rear;
            • driver and passenger chest airbags standard at front;
            • seatbelts with three anchor points, a force limiter and a warning light for all seats.
            The front seatbelts are fitted with pyrotechnic pretensioners and are heightadjustable on the saloon.
            • Isofix anchor points at the rear side seats.

            A protective, reinforced structure

            • Improved cabin protection in the event of frontal impact

            To satisfy the most stringent passive safety evaluation requirements, Citroën conducted extensive studies on protection from frontal impact.
            • The C4 features an additional impact absorbing system on the lower part of the front end to dissipate energy more effectively in the event of frontal impact.
            • This absorbing system is made up of a lower front bumper beam, along with subframe extensions.
            • The mechanical resistance of the front suspension and the lower subframe has been optimised to enable, for example, energy to be transmitted under the body in the event of frontal impact.
            • Studies were conducted on the movement of hard incompressible parts in the engine compartment in order to limit intrusions into the cabin.
            • The front doors have been reinforced in order to better stiffen the whole.

            Moreover, to reduce repair costs following minor impacts, the C4 features plastic front wings and an aluminium front upper bumper beam, which is integral with the impact absorbers. In the event of impact, the beam and impact absorbers crumple, without damaging the cantrails. The same is true for the lower bumper beam, which will crumple without damaging the engine subframe or its extensions.

            • Focus on pedestrian protection

            The C4 is designed to reduce the consequences of possible pedestrian impact.
            The subframe is equipped with two impact absorbers (one on the top part of the front end, the other on the lower part) to limit knee injury.
            Studies also focused on achieving a non-aggressive front end.
            For example, the boomerang-shaped headlamps are not only a key styling trait on the C4. They also contribute to pedestrian protection, since the headlamps are no longer on the top part of the bonnet, which is made of aluminium in order to absorb energy more effectively.

            Increased protection against theft and break-in

            The C4 offers excellent protection against theft and break-in. Key features are as follows:
            • side laminated glazing to protect the occupants and their property,
            • deadlocking,
            • a perimetric and volumetric alarm,
            • an engine immobiliser and transponder,
            • an unpickable electric boot lock,
            • antitheft nuts on each alloy wheel,
            • automatic relocking thirty seconds after the vehicle is unlocked if no door is opened,
            • automatic locking of the doors and boot as soon as the car starts to move.
