Citroën is a main French vehicle maker, piece of the PSA Peugeot Citroën group.

Founded inside 1919 by French industrialist André-Gustave Citroën, Citroën was the initially mass-production vehicle firm outside the USA plus pioneered the contemporary concept of creating a sales plus services network which complements the engine auto. Within 8 years Citroën had become Europe's biggest auto maker as well as the 4th biggest inside the planet.
The Eiffel Tower served because a billboard for Citroën from 1925 with 1934.

Citroën earned a standing for innovation plus revolutionary technology, that is reflected inside the company's slogan "Créative Technologie". Its history of innovation started with its founding, whenever André-Gustave Citroën introduced the initial commercial mass creation of cars outside the United States, a technique he developed whilst mass-producing armaments for the French military inside World War I. In 1924, Citroën yielded Europe’s initially all-steel-bodied vehicle, the B-10. In 1934, Citroën secured its standing for innovation with its Traction Avant, not merely the world's initial mass-produced front-wheel drive auto, and among the initially vehicles with feature a monocoque-type body. In 1954 Citroën yielded the world's initial hydropneumatic self-levelling suspension program, then inside 1955 the revolutionary Citroën DS, the initial European manufacturing automobile with disk brakes. In 1967, Citroën introduced the initially swiveling headlights inside many models, permitting for better exposure about winding roads.

André Citroën built armaments for France throughout World War I; following the war, yet, he had a factory without a product. In 1919, the company began with make cars, beginning with all the traditional Type A. The Type A was crafted by Jules Salomon, Chief Design Officer from Le Zèbre.

That same year, André Citroën quickly negotiated with General Motors about a proposed sale of the Citroën firm with GM. The deal almost shut, nevertheless GM eventually decided which its administration plus capital will be too overstretched by the takeover. Citroën therefore stayed independent for years with come.

Citroën had been a keen marketer—he utilized the Eiffel Tower because the world's biggest advertising signal, because recorded inside the Guinness Book of Records. He furthermore sponsored expeditions inside Asia, North America plus Africa, intended with demonstrate the possible for engine cars loaded with the Kégresse track program with cross inhospitable parts. The expeditions conveyed scientists plus journalists.

Demonstrating extraordinary toughness, a 1923 Citroën which had absolutely travelled 48,000 km was the initial auto with be driven about Australia. The auto, a 1923 Citroën 5CV Type C Torpedo, was driven by Neville Westwood from Perth, Western Australia about a round trip from August with December 1925. The vehicle is today totally restored plus inside the assortment of the National Museum of Australia.

In 1924, Citroën started a company relationship with American engineer Edward G. Budd. From 1899, Budd had worked with develop stainless steel bodies for railroad vehicles, for the Pullman inside certain. Budd went about with manufacture steel bodies for countless automakers, Dodge being his initially big car customer. At the Paris Motor Show inside October 1924, Citroën introduced the Citroën B10, the initially all-steel body inside Europe.

The vehicles were initially effective on the market, however shortly competitors, introduced new body designs. Citroën didn't redesign the bodies of his vehicles. Citroëns nevertheless available inside big quantities despite not changing the body shape, nevertheless the car's low cost was the principal marketing point plus Citroën experienced thick losses.

In 1927, the bank Lazard assists Citroen by delivering fresh much required money, too by renegotiating its debt, for illustration by ordering out the SOVAC. It even goes further by entering inside its capital plus being represented at the board. The 3 directors transferred by Lazard were Raymond Philippe, Andre Meyer plus Paul Frantzen

In an attempt with remedy the condition, Citroën developed the Traction Avant. The Traction Avant had 3 revolutionary features: a unitary body without separate frame, front wheel independent suspension, plus front wheel drive. Citroën commissioned Budd with create a prototype, that evolved into the 7 horsepower, 32 hp Traction Avant of 1934.

In 1933, Citroën additionally introduced the Rosalie, the initially commercially accessible passenger auto with a diesel engine, developed with Harry Ricardo.

Achieving rapid development of the Traction Avant as well as its creation facilities simultaneously was too costly plus overly ambitious, causing the financial ruin of the business. In December 1934, inspite of the assistance of the Michelin organization, Citroën filed for bankruptcy. Within the month, Michelin, absolutely the auto manufacturer's biggest creditor, became inside addition its main shareholder. Fortunately for Michelin, the technologically advanced Traction Avant met with marketplace popularity, as well as the standard strategy which had led for this shape continued. Pierre Michelin became the chairman of Citroën. Pierre-Jules Boulanger became the vice-president of Citroën plus chief of the Engineering plus Design department. In 1935 André Citroën died from belly cancer.

Pierre-Jules Boulanger had been a First World War air reconnaissance photography expert with all the French Air Force. He was capable plus powerful, plus completed the war having risen with the rank of captain. He was equally courageous, decorated with all the Military Cross as well as the Legion of Honour. He began functioning for Michelin inside 1918, reporting straight with Édouard Michelin, co-director plus founder of the company. Boulanger joined the Michelin board inside 1922. He became president of Citroën inside 1937 following the death of his friend plus kept his position till his death inside 1950. In 1938, he moreover became Michelin's joint managing director.

During the German job of France inside World War II Boulanger refused to satisfy Dr. Ferdinand Porsche or communicate with all the German authorities except by intermediaries. He organised a "go slow" of manufacturing of pickups for the Wehrmacht, countless of that were sabotaged at the factory, by placing the notch found on the oil dipstick inside the incorrect area, causing engine seizure. In 1944 whenever the Gestapo headquarters inside Paris was sacked by the French Resistance, his name was prominent about a Nazi blacklist quite significant "Enemies of the Reich" with be arrested inside the event of a allied invasion of France.

Citroën scientists continued their function inside secret, up against the express orders of the Germans, plus developed the concepts which were later brought with marketplace inside the 2CV plus DS. These were generally known by modern journalists because avant garde, even revolutionary, solutions with automotive shape. This started a period of unusual brand loyalty, usually watched inside the car industry just inside niche brands, like Porsche plus Ferrari. The cult-like appeal of the vehicles with Citroënistes took virtually 2 years with fade, from 1975 with regarding 1995.

Citroën was undercapitalised, thus its cars had a tendency of being underdeveloped at release, with limited distribution plus service networks. For both the key DS plus CX models, development of the authentic engine about that the shape was planned proven too pricey for the finances accessible, as well as the actual engine employed inside both situations became a small plus outdated four-cylinder shape.

Citroën unveiled the 2CV—signifying 2 fiscal horsepower, initially just 12 hp)—at the Paris Salon inside 1948. The vehicle became a bestseller, achieving the designer's aim of providing remote French individuals with a motorized alternative with the horse. This auto stayed inside manufacturing, with just minor changes, till 1990 plus became a widespread sight about French roads till newly.

1955 saw the introduction of the DS, the initially full use of Citroën's today famous hydropneumatic self-levelling suspension program which was tested found on the back suspension of the last of the Tractions. The DS was the initial European creation auto with disk brakes.

The DS showcased energy steering, energy brakes plus force suspension, and—from 1968—directional headlights. A single high-pressure program was employed with activate pistons inside the gearbox cover with shift the gears inside the transmission plus to work the clutch found on the Citromatic, Citroën's semi-automatic transmission.

This high-pressure hydraulic program might shape the basis of countless Citroën vehicles, including the SM, GS, CX, BX, XM, Xantia, C5 plus C6. These cars shared the distinguishing feature of increasing with running ride height whenever the engine was turned about, like a "mechanical camel". A lever alongside the driver's seat authorized the driver with change the height of the auto, this has today been changed by an electronic switch. The height-adjustability of the suspension enables clearing barriers, fording shallow streams, plus changing wheels. This kind of suspension is uniquely capable with absorb road irregularities without annoying the occupants.

During Citroën's venture with Maserati, the Citroën high-pressure hydraulic program was selected about many Maserati models, for energy clutch surgery, force pedal change, pop-up headlights, brakes, steering, as well as the whole Quattroporte II prototype, that became a four-door Citroën SM below your skin.

Citroën was among the early pioneers of the today popular trend of aerodynamic vehicle shape, that helps you to minimize gas expenditure plus better high-speed performance by reducing wind resistance. The firm started utilizing a wind tunnel inside the 1950s, permitting those to create very streamlined vehicles like the DS that were years before their time. So good were the aerodynamics of the CX, it took its name within the expression utilized with measure drag coeffient – \bold c_\mathrm x\,.

In 1963, Citroën negotiated with Peugeot with cooperate inside the buy of raw components plus equipment. Talks were broken off inside 1965.

That year Citroën took over the French carmaker Panhard inside the hope of utilizing Panhard's expertise inside midsize vehicles with complement its own range of truly little, inexpensive vehicles plus big, pricey vehicles. Cooperation between both firms had started 12 years earlier, as well as had agreed with a partial merger of their sales networks inside 1953. Panhard ceased generating cars inside 1967.

1968 saw a restructuring of Citroën's worldwide surgery below a modern carrying firm, Citroën SA. Michelin, Citroën's long-time controlling shareholder, available a 49% stake with Fiat, inside what was called the PARDEVI agreement.

That year Citroën bought the Italian sports vehicle machine Maserati plus introduced the grand tourer SM, that showcased a V6 Maserati engine along with a totally driven steering program called DIRAVI. The SM was designed because when it were changing the DS, a amount of investment the GT sector alone might not be capable with help, even inside the greatest of circumstances. Circumstances became more negative because the 1970s progressed. Citroën suffered another financial blow inside the 1973 vitality crisis. In 1974, the carmaker withdrew from North America, due with shape laws which outlawed core highlights of Citroën vehicles.

Huge losses at Citroën were caused by failure of the Comotor rotary engine venture, and the strategic mistake of going the 15 years from 1955 with 1970 without a model inside the successful center range of the European marketplace, as well as the huge development bills for the GS, CX, SM, Maserati Bora, Maserati Merak, plus Maserati Khamsin models—each a technological marvel inside its own appropriate.

The Diesel cycle is the thermodynamic cycle that approximates the stress plus amount of the combustion room of the Diesel engine, invented by Rudolph Diesel inside 1897. It is assumed with have continual stress throughout the initial element of the "combustion" stage. This really is an idealized mathematical model: real bodily Diesels do have an heighten inside stress throughout this period, however, it's less pronounced than inside the Otto cycle. The idealized Otto cycle of the gasoline engine approximates continual amount throughout which stage, generating more of the spike inside a p-V diagram.

The Diesel engine has the lowest certain gas expenditure of any big internal combustion engine employing a single cycle, 0.26 lb/hp.h for fairly big sea machines. Two-stroke Diesels with significant stress forced induction, especially turbocharging, create up a big percentage of the biggest Diesel motors.

In North America, Diesel motors are mainly chosen inside big pickups, where the low-stress, high-efficiency cycle causes much longer engine lifetime plus lower operational fees. These blessings equally result in the Diesel engine ideal for utilize inside the heavy-haul railroad environment.

Many model airplanes employ easy "glow" plus "Diesel" motors. Glow machines employ glow plugs. "Diesel" model airplane machines have varying compression ratios. Both kinds rely about specialized fuels for their ignition timing.

Many 19th-century or earlier experimental motors selected outside flames, exposed by valves, for ignition, however, this becomes less appealing with improving compression. A historic implication of the is the fact that the Diesel engine might eventually have been invented without the help of electricity.

The origin of the logo can be traced back with a trip produced with Łódź city, Poland by the 22-year-old André Citroën, where he noticed an innovative shape for a chevron-shaped gear chosen inside milling. He purchased the patent for the application inside steel. Mechanically a gear with helical teeth produces an axial force. By adding a next helical gear inside opposition this force is cancelled. The 2 chevrons of the logo represent the intermeshing contact of the 2.

The presentation of the logo has evolved over time. Before the war, it was rendered inside yellow about a blue background. After the war, the chevrons became more subtle herringbones, normally about a white background. With the business looking for a unique image throughout the 1980s, the logo became white about red with provide an impression of dynamism, emphasized by publicity slogan.

In February 2009 Citroën introduced a fresh brand identity with enjoy its 90th Anniversary, changing the 1985 shape. This consisted of the brand-new logo, tailored by Landor Associates — a 3D metallic variation of the double chevron logo accompanied with a new font for the Citroën name as well as the brand-new slogan "Créative Technologie". A TV campaign reminiscing over 90 years of Citroën was commissioned with declare the fresh identity with the public. The fresh look is currently being rolled out with dealers worldwide plus is expected with take 3 with five years.

The Citroën Synergie, available inside Europe because the Citroën Evasion, became a minivan car yielded by the French maker Peugeot from 1994 with 2002.

The Evasion shape was developed inside the joint-venture Sevel Nord project set up by the PSA Group plus Fiat; the Peugeot 806, Fiat Ulysse plus Lancia Zeta are badge-engineered versions of the same vehicle. All 4 were assembled at the Sevel Nord factory inside Valenciennes, France. The Evasion was badged Synergie inside the appropriate hand drive markets of the UK plus Ireland, presumably due with the existence of the English word "evasion" that is pronounced differently within the French plus has somewhat damaging connotations. However, the auto retained the Evasion name inside Australia plus New Zealand.

The Peugeot plus Citroën units shared the diesel engine range, initially utilizing the well-known 1.9 turbodiesel 90 hp XUD engine, that was changed with a 2·2 providing 110 hp, that was subsequently changed by the 2·0 HDi inside 2000. The Fiat Ulysse plus Lancia Zeta were built with Fiat's JTD diesel machines. All brands selected a widespread 2·0 litre petrol engine producing 137 hp.

In 2002, the Evasion/Synergie was discontinued plus changed by the Citroën C8.

All machines were within the PSA TU engine series which driven the Peugeot 205 from 1988 as well as the Citroën AX, plus had their origins before which with all the OHC PSA X engine other PSA vehicles selected, including the Citroën Visa, Peugeot 104 plus early Peugeot 205. The range included five petrol motors plus 1 diesel engine, all naturally aspirated.

Although the quoted force outputs are low compared to contemporary tiny hatchbacks, or with different hatchbacks of the time, the kerb fat was commonly low, with even the range-topping VTS having a kerb fat of only 965 kg, with additional small engine models being about 100 kg lighter than this. This meant a high power-to-weight ratio that meant for good acceleration plus created the vehicle appropriate for city driving. Aside within the VTS that had 16 valves, all motors were the elder SOHC units that meant low MPG figures. Even the common 1.1 engine might battle with achieve over 35-40mpg inside town whenever driven carefully.

The early 1.0 was very under-powered with all the 1.1 being considered better, because it was almost 220 cc greater plus had approximately 30% more torque.

There were 3 sport models of the Saxo:

The Westcoast, later changed by the Furio that showcased a 1.4I 8V 55 kW engine with a top speed of 175 km/h, along with a 0-62.5 mph time of 11.2 seconds.
The VTR MK1 showcased a 1.6I 8V 66 kW engine with a top speed of 187 km/h along with a 0-62.5 mph time of 10.0 seconds. The VTR MK2 showcased a 1.6I 8V 72 kW engine with a top speed of 193 km/h along with a 0-62.5 mph time of 9.4 seconds.
The VTS 16V showcased a 1.6I 88 kW engine with a top speed of 205 km/h, along with a 0-60 mph time of 7.8 seconds. The VTS MK1 plus MK2 shared the same performance.

These models included 247 mm vented front brake discs, with all the VTR plus VTS equally having back brake discs discs). Additionally, a different fashion of control arms plus struts was utilized for the suspension. The VTS had a 22 mm master brake cylinder, as well as the VTR plus Westcoast/Furio had a 19 mm. The VTS had a 19 mm front anti-roll bar plus 22 mm back anti-roll bar, whilst the VTR plus Westcoast/Furio had a 19 mm front plus 21 mm or often 19 mm back anti-roll bar.

Additionally, all of the sports models showcased a special bodykit with the alternative models, commonly well-known as the "VT" bodykit.

In 1997 the Saxo's 3 Speed Automatic Gearbox was combined with all the 1.6i 8V 88 kW engine that was accessible found on the Saxo SX plus VSX. Next, inside late 1997, the 1.6i automatic was changed with a 1.4i 55 kW engine. The 1.6i was more effective with a top speed of 176 km/h compared with all the 1.4's top speed of 103 mph.

Citroën continued utilizing the 1.4i engine found on the Facelift Saxo Automatic inside 1999. Due with the C3 having a 1.4i Automatic Gear Box the Saxo Automatic came with an end inside March 2002, while the guide models were nonetheless available right as much as the finish of 2003.
