Citroen Launches Compact Diesel Luxury in the C4 HDI 2.0 Litre

February 1st, 2008





Citroen, already at the cutting edge of the diesel market in Australia with its range of diesel sedans, wagons, hatches and people movers, has added yet another diesel model to its range, with the launch of the Citroën C4 HDi 2.0 litre automatic, taking diesel performance into the luxury market sector.

 

“The arrival of this new variant of the Citroën C4 range is a clear illustration of how the diesel car market in Australia is maturing,” says Miles Williams, General Manager for Citroën in Australia. “Until now diesel sales have been primarily driven by their economy and environmental benefits and, therefore, the top sellers have been versions that optimize the price equation. However, starting with the launch of the Citroën C6, our range-topping super-luxury model, in which the majority of sales are diesel powered, we are now seeing increasing demand for the top trim and equipment variants to be diesel powered, with owners wishing to combine comfort with economy.”

 

Following the launch of the Citroën C4 Picasso, in which the majority of sales are for the 2.0 litre Turbo Diesel mated to the six speed automatic gearbox, Citroën have now slotted this drive train into the Citroën C4 hatch with the highest trim and equipment level to produce a compact car that blends luxury, economy, environmental performance and performance.

 

Powered by Citroën’s 100 kW 2.0 Turbo Diesel engine, the new Citroën C4 HDi 2.0 litre can dispatch the dash to 100 kmh in just 10.4 seconds, yet, at the same time, offer an open road fuel consumption of just 5.1 litres per 100 km. The combination of an advanced six speed automatic gearbox and 320 Nm of torque – which is lifted to 340 under acceleration with the ‘overboost’ feature – provides effortless performance across all speeds and under all conditions. The Turbo Diesel engine’s inherent economy also provides the luxury of reducing the number of fuel stops, with a range of 1000 km readily available on open road journeys.

 

Like the other variants in the Citroën C4 range, the new C4 HDI 2.0 shares an award-winning design that has been acclaimed as much for its good looks as its intelligent design and market sector leading safety. It shares its trim and equipment level with the Citroën C4 2.0 petrol version.

Over the standard C4 HDI, already a comprehensively well equipped car in its own right, the new C4 HDI 2.0 litre gains:

·        Alloy wheels

·        Body coloured door handles and mirrors

·        Rear lip wing

·        Leather Steering Wheel

·        5 stack CD changer in the front armrest

·        Automatic light sensing interior rearview mirror

·        Velour upholstery

·        Dual Zone Climate Control Air Conditioning

·        Rear seat centre armrest with hidden locker

·        Automatic headlights

·        Door sill and footwell lights

·        Chrome interior trim features

 

Additionally, the HDi 2.0 is available with options not available on the 1.6 litre, including a full leather interior with heated front seats, electric operation of the front seats and memory settings on the driver’s seat, as well as the option of front and rear parking sensors.

 

“The new diesel Citroën C4 HDi 2.0 provides a natural compliment for the existing diesel variant, the C4 HDI EGS,” says Miles Williams. “The C4 HDi EGS, which arrives in Brisbane with a two month waiting list, such is its popularity, is fully optimized to provided the best running costs.”

 

“It has the most efficient diesel engine and this is mated to the EGS gearbox which provides fuel economy and emissions even better than a manual gearbox, which is then blended with a trim and equipment that provides an unbeatable price equation. The new model will sit at the other end of the C4 range for owners who want to combine the unquestionable advantages of a diesel with a full featured and equipped car. It is a clear example of the market shift seen in Europe, where owners wish to own a smaller, more economical and clearer car, but at the same time not give up features, equipment and performance. The new C4 HDi 2.0 fully delivers this new ownership equation,” says Mr Williams.

 

The new Citroën C4 HDi 2.0 six speed automatic has a recommended retail price of $35,990, plus on road costs.

 

 


      CITROËN C4: ONE MODEL, TWO CARS

 

The Citroën C4 is available in two very distinct versions, a spacious five door hatchback and a true coupé that is much more than a two door version of the five door, from the base of the ‘A’ pillar back, the Coupé is an entirely different car in style, character and image. But they both share a strong clarity and decisiveness of styling that makes both models clearly Citroëns.

 

THE C4 STYLE: FLUID LINES AND STRONG AERODYNAMICS

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, powerful 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 rear-view 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.

 

A SALOON OF ASSERTIVE DESIGN

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.

 

A COUPÉ WITH A DIFFERENCE

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.

 

 

C4 COMBINES AERODYNAMIC DESIGN & GENEROUS SPACE

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

 

BEST Cd IN ITS CATEGORY

Easily identifiable as Citroën vehicles through their design lines and proportions, the C4 Saloon and C4 Coupé also embody one of the Citroen’s traditional strengths: aerodynamics.

 

Extensive aerodynamic studies were conducted on the C4 in order to obtain a drag coefficient of from 0.28 for the coupé, a record in this segment. The saloon boasts a Cd from 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 rear-view 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.

 

CLASS-BEATING INTERIOR SPACE

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.

 

 

INNOVATIONS FOR ON-BOARD COMFORT AND RELAXED DRIVING

 

 

The interior of the C4 boasts a host of innovations in driving ergonomics, life on-board and functional convenience.

 

DRIVING ERGONOMICS

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 controls are positioned in the centre of the dashboard so that the passengers can control the features that affect passenger comfort.

 

With the C4, onboard comfort means safety and well-being.

 

The multifunctional fixed-hub 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.

·        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 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;

·        With 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 the Citroën C8 MPV. The centre features three display units:

·        A translucent instrument cluster,

·        A multifunction screen with the on-board computer,

·        An air-conditioning display unit.

 

The central translucent instrument cluster

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

 

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.

 

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 optional glazed panoramic roof and the standard scented air freshener.

 

The scented air freshener

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

 

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.

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.

 

To reflect customers’ tastes more effectively, the C4 is equipped with “comfort” or “sport” 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.

 

“Sport” seating, which is fitted as standard to the Coupé, is firmer to the touch with more pronounced support. It corresponds to the pursuit of stronger driving sensations and a more dynamic driving style.

 

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 rear-view 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 rear-view 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.

 

 

Individual thermal comfort

To satisfy requests for individual comfort functions at the front, the 2.0 litre versions of the C4 feature 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.

 

 

PRACTICAL CONVENIENCE

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 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 flexibility

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.

 

 

CITROËN C4: ENJOYABLE, RELAXED DRIVING

 

On-board comfort also means enjoyable, relaxed driving in all circumstances. For this reason, in addition to its wide range 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.

 

 

INNOVATIVE AND MODERN DRIVING AIDS

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.

 

Xenon dual-function directional headlamps

The Citroën C4 is available with an optional feature that remains rare in this segment: Xenon dual function 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 Citroën 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 optional front parking assistance, alongside the rear parking assistance function. Rear parking assistance is standard on the Coupe VTS versions and the front assistance is a factory-fitted option.

 

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

Standard C4 Coupe VTS, 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.

 

 


CITROËN C4; ADVANCED ENGINE CHOICE

 

The Citroën C4 is offered with a choice of four engines ideally suited to Australian conditions with the 1.6 litre, 2.0 litre and 2.0 litre high performance engines available and two advanced diesel engines.

 

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 with the C4 Saloon offers 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 was 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 DIESEL C4

The C4 is equipped with a choice of two advanced HDi Turbo Diesel engines, both of which are equipped with the second generation common-rail system.

 

1.6 litre HDi engine

The characteristics and performance of this compact, low weight engine is exceptional driving pleasure, reduced fuel consumption and pollutant emissions are combined with acoustic comfort and vibration control.

 

The engine is also remarkable for is verve and for the temporary torque increase of 20 Nm made available by the overboost function.

 

The 1.6 HDi engine offers an output of 80 kW EEC (110 bhp) at 4,000 rpm and was 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.

 

1.6 Litre HDI Engine with the EGS gearbox

EGS is an all new gearbox for the turbo diesel Citroën C4 that combines the best features of a manual gearbox, optimized responsiveness and performance, with the best features of an automatic, self-shifting convenience and adds an extra twist – it is more economical and generates less greenhouses gas – CO2 – than the normal manual.

 

The heart of this seemingly impossible contradiction is Citroën’s new EGS gearbox. At its most basic level it is a six speed manual gearbox with a conventional clutch. The gears are selected and the clutch is operated by robotized electro hydraulic actuators.

 

However, unlike less sophisticated robots, where the actuator unit is slapped on to an existing gearbox, this new Citroën unit has been designed from day one as a robotized unit, with all its operational systems fully integrated into the gearbox. This means that EGS can change gears in just 0.8 second, when called upon for the quickest possible gearchange.

 

EGS is also a chatty robot, ‘talking’ all the time not just to the engine, but also all of the car’s electronics, enabling it to optimize gear changes and work with the engine, brakes and chassis electronics such as the electronic stability programme. For all his technology and ability, the EGS robot is no heavy weight, adding just 12 kilos to weight of the C4 HDI, remarkably small figure considering it also has an extra gear over the normal HDi.

 

This not only makes for smoother operation. It also makes the EGS gearbox more efficient, hence better fuel consumption and lower CO2 emissions.

 

Translated into on the road use, this means that on the open road the roomy, spacious Citroën C4 EGS is offering a remarkable 4.5 litres per 100 km, while even around town this medium size family hatch is achieving 5.8 litres per 100 km. On the CO2 front, it boasts an average figure of 120 grams per km., an outstanding performance for a car of this size and one which already beats the proposed ultra-tough EU figure of 125 g/km for 2012.

 

2.0 litre HDi Engine

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. Fitted with a six speed electronic automatic gearbox, this version of the Citroën C4 has a top speed of 206 kmh and the 0-100 kmh time is 10.4 seconds. The combined fuel consumption is 6.6 l/100 km for the automatic.

 

IMPECCABLE ROAD MANNERS

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 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 ABS 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 fitted as standard to the Turbo Diesel and 2.0 litre petrol versions. It is coupled with traction control to prevent skidding. This system can be disconnected with the 130 kW 2.0i 16V engine.

 

HIGH-LEVEL PASSIVE SAFETY

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 front airbags standard;

·        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 height adjustable on the saloon.

 

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 structure.

 

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:

·        Deadlocking,

·        An optional 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.
