Citroën DS5
The DS 5 is a compact executive hatchback which was designed and developed by the French automaker Citroën, and launched in the market in Europe in November 2011. It was the third model in the premium sub brand DS. Released as the Citroën DS5, the car was relaunched as the DS 5 in 2015, following Citroën's decision to rebadge its DS models and market them under the brand DS. Details The DS5 was revealed at the 2011 Shanghai Auto Show in April 2011. Although Peugeot and Citroën products have shared platforms and principal components since the closing decades of the twentieth century, the DS5 became in 2011 the first Citroën branded car to be assembled in Peugeot's lead European plant at Sochaux. The DS5 mixes hatchback and estate styling, resembling a shooting-brake. It is long and wide, dimensions that are similar to those of the Lancia Delta. This is hardly a coincidence: the DS5 is based on the PF2 platform as 3008 is too, not on the C5 as its name could ...

DS Automobiles
DS Automobiles is a French luxury vehicle marque which was introduced in 2009. Formerly part of Citroën, DS has been a standalone brand since 2015 (2012 in China). DS can be an abbreviation of Different Spirit or Distinctive Series, although it is also considered a nod to the classic executive car Citroën DS. The name is also a play on words, as in French it is pronounced like the word ', meaning "goddess". History The PSA Group originally consisted of three automobile brands, Peugeot, Citroën and the soon dropped Talbot, but none was considered a "premium" brand. Since 1976, PSA has experimented with differentiating the brands by price level, similar to Chevrolet/Buick or Volkswagen/Audi, but neither brand had the strength to justify premium pricing. By launching the DS line, Groupe PSA decided to build on the design heritage of the original Citroën DS (1955–1975) designed by Flaminio Bertoni and André Lefèbvre. The DS line started with the Citroën DS3 in the be ...

Gasoline Direct Injection
Gasoline direct injection (GDI), also known as petrol direct injection (PDI), is a mixture formation system for internal combustion engines that run on gasoline (petrol), where fuel is injected into the combustion chamber. This is distinct from manifold fuel injection systems, which inject fuel into the intake manifold. The use of GDI can help increase engine efficiency and specific power output as well as reduce exhaust emissions. The first GDI engine to reach production was introduced in 1925 for a low-compression truck engine. Several German cars used a Bosch mechanical GDI system in the 1950s, however usage of the technology remained rare until an electronic GDI system was introduced in 1996 by Mitsubishi for mass-produced cars. GDI has seen rapid adoption by the automotive industry in recent years, increasing in the United States from 2.3% of production for model year 2008 vehicles to approximately 50% for model year 2016.

Premium Segment
Premium pricing (also called image pricing or prestige pricing) is the practice of keeping the price of one of the products or service artificially high in order to encourage favorable perceptions among buyers, based solely on the price. Premium refers to a segment of a company's brands, products, or services that carry tangible or imaginary surplus value in the upper mid- to high price range. The practice is intended to exploit the tendency for buyers to assume that expensive items enjoy an exceptional reputation or represent exceptional quality and distinction. A premium pricing strategy involves setting the price of a product higher than similar products. This strategy is sometimes also called skim pricing because it is an attempt to “skim the cream” off the top of the market. It is used to maximize profit in areas where customers are happy to pay more, where there are no substitutes for the product, where there are barriers to entering the market or when the seller cannot sa ...

Citroën
Citroën () is a French automobile brand. The "Automobiles Citroën" manufacturing company was founded in March 1919 by André Citroën. Citroën is owned by Stellantis since 2021 and previously was part of the PSA Group after Peugeot acquired 89.95% share in 1976. Citroën's head office is located in the Stellantis Poissy Plant in Saint-Ouen-sur-Seine since 2021 (previously in Rueil-Malmaison) and its offices studies and research in Vélizy-Villacoublay, Poissy (CEMR), Carrières-sous-Poissy and Sochaux-Montbéliard. In 1934, the firm established its reputation for innovative technology with the Traction Avant. This was the world's first car to be mass-produced with front-wheel drive, four-wheel independent suspension, as well as unibody construction, omitting a separate chassis, and instead using the body of the car itself as its main load-bearing structure. In 1954, they produced the world's first hydropneumatic self-levelling suspension system then, in 1955, the revolutio ...

Automated Manual Transmission
The automated manual transmission (AMT) is a type of transmission for motor vehicles. It is essentially a conventional manual transmission but uses automatic actuation to operate the clutch and/or shift between gears. Many early versions of these transmissions that are semi-automatic in operation, such as ''Autostick'', which automatically control only the clutch — often using various forms of clutch actuation, such as electro-mechanical, hydraulic, pneumatic, or vacuum actuationhttp://hudsonterraplane.com/tech/other/DrivemasterServiceInformation.pdf — but still require the driver's manual input and full control to initiate gear changes by hand. These systems that require manual shifting are also referred to as clutchless manual systems. Modern versions of these systems that are fully automatic in operation, such as ''Selespeed'' and ''Easytronic'', can control both the clutch operation and the gear shifts automatically, by means of an ECU, therefore requiring no manu ...

Electric Engine
An electric motor is an electrical machine that converts electrical energy into mechanical energy. Most electric motors operate through the interaction between the motor's magnetic field and electric current in a wire winding to generate force in the form of torque applied on the motor's shaft. An electric generator is mechanically identical to an electric motor, but operates with a reversed flow of power, converting mechanical energy into electrical energy. Electric motors can be powered by direct current (DC) sources, such as from batteries, or rectifiers, or by alternating current (AC) sources, such as a power grid, inverters or electrical generators. Electric motors may be classified by considerations such as power source type, construction, application and type of motion output. They can be powered by AC or DC, be brushed or brushless, single-phase, two-phase, or three-phase, axial or radial flux, and may be air-cooled or liquid-cooled. Standardized motors provide con ...

Diesel Engine
The diesel engine, named after Rudolf Diesel, is an internal combustion engine in which ignition of the fuel is caused by the elevated temperature of the air in the cylinder due to mechanical compression; thus, the diesel engine is a so-called compression-ignition engine (CI engine). This contrasts with engines using spark plug-ignition of the air-fuel mixture, such as a petrol engine ( gasoline engine) or a gas engine (using a gaseous fuel like natural gas or liquefied petroleum gas). Diesel engines work by compressing only air, or air plus residual combustion gases from the exhaust (known as exhaust gas recirculation (EGR)). Air is inducted into the chamber during the intake stroke, and compressed during the compression stroke. This increases the air temperature inside the cylinder to such a high degree that atomised diesel fuel injected into the combustion chamber ignites. With the fuel being injected into the air just before combustion, the dispersion of the fuel is ...

Straight-4
A straight-four engine (also called an inline-four) is a four-cylinder piston engine where cylinders are arranged in a line along a common crankshaft. The vast majority of automotive four-cylinder engines use a straight-four layout (with the exceptions of the flat-four engines produced by Subaru and Porsche) and the layout is also very common in motorcycles and other machinery. Therefore the term "four-cylinder engine" is usually synonymous with straight-four engines. When a straight-four engine is installed at an inclined angle (instead of with the cylinders oriented vertically), it is sometimes called a slant-four. Between 2005 and 2008, the proportion of new vehicles sold in the United States with four-cylinder engines rose from 30% to 47%. By the 2020 model year, the share for light-duty vehicles had risen to 59%. Design A four-stroke straight-four engine always has a cylinder on its power stroke, unlike engines with fewer cylinders where there is no power stroke occu ...
