The Citroën C4 is a small family car produced by French automaker Citroën since autumn 2004. The C4 was designed to be the successor to the Citroën Xsara. It is mechanically similar to the Peugeot 308, which was launched in 2007. A revised version with new front end, reverse light and dashboard revisions was launched for the 2008/09 model year. In January 2010 it was announced that the Coupe version was to be discontinued in favour of the new Citroën DS4. The C4 came in 2nd place in the 2005 European Car of the Year awards.
To cope with this difficult part of the market, the Citroen is greatly committed to building a new model that would capture the interest of a large chunk of customers: the Geneva Motor Show in 2004 was presented the C4 Sport, a concept from the lines definitive made??-bodied coupe and prefigured among other things, the willingness of the French company to employ it in competition. The car was finally unveiled at the Paris however, both as a coupe, both as a hatchback and 5 door.
Designed by a team that included among others Donato Coco and Jean Pierre Ploué, the C4 was indicated by the press as the car that marked a distinct return to a style French company from the pack. Building on the floor of her cousin, the Peugeot 307, the C4 was immediately made available in two body variants: hatchback 5-door hatchback and coupe three-door.
The front is common to both versions, with the grille formed from virtually extensions of the central crest. The most characteristic is the area instead of the pavilion: the sedan is much more rounded and soft shapes, so they can boast a Cd of just 0.28, while the coupe is decidedly angular, with a rear split into two parts and lights back.
The rear window of the coupe version, decidedly unconventional, reminiscent of the old Honda CRX start of the nineties and the last three-door Mazda 323 C BA. From these two versions of the C4 Picasso is more detached, taking over the grille of the sedan and coupe, but the cut of the headlamps is different, always a mix of corners and curves. Instead, the rear lights incorporate the design as those of the sedan, but adapted to the different conformation of the body. Internally we have: the bridge you see a large screen placed in the top center of the bridge itself, which acts as a digital speedometer display and also provides, again in digital format, the usual features speedometer, oil temperature and fuel level.
The revolution, however, is placed in canonical position, behind the wheel. The latter, of a multifunction is characterized by having a fixed hub. The cabin is equipped with numerous storage compartments and luggage compartment is regular in shape and has a capacity of 352 liters, arriving at 1,200 lowering the rear seat backrest. The load threshold is quite high, hitting the loads of heavy objects. Also deserve to be mentioned laminated side windows and exterior mirrors with casing specially designed to prevent wind noise and improve comfort inside.
The saloon version is manufactured in Argentina, where it is sold alongside the three-door version; it is exported from there to Brazil and Hungary as the C4 Pallas, to Spain as the C4 Berline and to Turkey and Greece as the C4 Sedan. A four-door saloon version is also built and sold in China as the Citroën C-Triomphe. A panel van based on the coupé bodyshell is available in some markets, including Ireland.
A major selling-point of the C4 is its extensive use of technology. For example, the car features the “Lane Departure Warning System” (only in the top-of-the-range “Exclusive” model), which alerts the driver if he or she crosses a road marking without using the turn signals; directional headlights; perfume dispenser integrated into the ventilation system; translucent dashboard, transparent glass roof; ESP (Electronic Stability Program), and a fixed steering wheel hub which lets the driver operate several functions of the car without removing his or her hands from the wheel.
The fixed hub also allows for the first production use of a “shaped” driver airbag. Because the hub maintains a constant position, the airbag can be optimally shaped to spread the load across the greatest possible area of the driver’s body in a collision, thus reducing the chances of serious injury. In addition, the car features an innovative centrally mounted translucent LCD speedometer display that remains clearly visible in all lighting conditions.
Surprisingly, given the emphasis put on technology, the car’s In-Car Entertainment, while well integrated into the car’s information system via CAN Bus, is not DAB ready. MP3 playback is supported by the entry level audio system and high-end audio with double layer sound insulated windows and integrated navigation system is available as extra. In September 2007, a USB box accessory was released to enable full iPod connectivity with the standard RD4 radio.
The C4 does not feature Citroën’s Hydractive suspension, which is reserved for higher class models, such as the C5 and C6. The Picasso version can get a pneumatic rear suspension. The C4 breaks with the past on other fronts, in particular by removing the rear autodirezionale solution, used up to that time of the Xsara and ZX.
The suspension was very classic, and included the usual type MacPherson strut front suspension with coil springs while the rear was interconnected wheels with torsion beam and torsion bars. The braking system includes ventilated discs front and rear solid discs with ABS and ESP (not standard versions with basic fittings). The steering is rack and pinion steering with electrohydraulic.
At the end of 2008, the C4 hatchback and coupe are subject to a slight cosmetic makeover that involves first the front, this time sporting a “mouth” and larger trapezoidal. The grille has been redesigned making it now slightly curved. There were also minor updates in the queue. The redesign has also led to a slight lengthening of the car body, and was the occasion for more news.
From the mechanical point of view is in fact the arrival of 1.6 Prince, with variable valve timing is aspirated, turbocharged and direct injection, already mounted on the Peugeot 207 and 308 and the Mini. Greatly improved ride comfort, and also revised the list, the more simplified and the sedan and the coupe offers the same price. In addition, the diesel versions are available with Airdream pack, which allows to slightly reduce emissions and consumption.
The sedan version was introduced as Citroën C-Triomphe, a mid-size sedan automobile produced from 2006 for the chinese market by Dongfeng Peugeot-Citroën Automobile, a joint venture between the French PSA Group (Peugeot-Citroën) and the Chinese manufacturer Dongfeng.
This new model range was designed to supplement other chinese models in the range such as the Fukang and the Elysée, rather than being any direct replacement.
In April 2007, Citroën announced that the four-door C4 would be built in Argentina. The Argentinian and Brazilian versions are sold as the C4 Pallas in some South American and European markets.
The car is a notchback sedan version of the european C4 model, since the chinese market prefers traditional three-box sedans over hatchbacks. It did not keep the designation, however, because in Chinese the number “4” is unlucky. The sedan is much larger than the hatchback: its length is 4,770 mm (187.8 in) over the hatchback’s 4,260 mm (167.7 in) and its wheelbase measures 2,710 mm (106.7 in) against 2,610 mm (102.8 in) of the hatchback. This caused the C-Triomphe sedan to be classified in large family car class. The C-Triomphe has a number of unique features, such as an integrated air freshener which allows the driver to choose the smell of the interior.
In 2009, the C-Triomphe was accompanied by the Citroën C-Quatre, a smaller (length 4,588 mm (180.6 in), wheelbase 2,610 mm (102.8 in)), cheaper and more fashionably styled sedan version of the C4. For 2012 Citroën planned a new facelift version of the C-Quatrè sedan to unveil at Shanghai Motor Show based on the first generation of european C4.
The C4 Picasso is the MPV version of C4 range. Was offered since 2006 in two version: 5-seat more compact and 7-seat called Grand C4 Picasso. The C4 Picasso received a facelift in 2010 which are updated engines, headlights and mechanics. The engine range is composed largely of the same version of the engine hatch and coupé plus the petrol 1.8, also available in bi-fuel (natural gas or LPG) in many markets.
