95-791: The Lupo was introduced in October 1998, to fill a gap at the bottom of the Volkswagen model range caused by the increasing size and weight of the Polo . The right-hand-drive version for the UK market was launched in the spring of 1999. In Japan, it was launched in July 2001. Lupo uses the A00 platform which is a shortened version of the Polo/Ibiza A0 platform . Initially only available in two trim variants,

190-573: A coupé , the Volkswagen Polo Coupé. Unusually, the third (and new) body that was actually marketed as the Volkswagen Polo Hatchback was closer in concept to a small estate, albeit with exactly the same wheelbase and floor pan as the coupé instead of the (longer) saloon. This latter version, also known as the squareback (in the original German brochures, "steilheck", literally "steep tail"), amongst other nicknames,

285-498: A half-life of 717,000 years. Excessive quantities of stable Mg have been observed in the Ca-Al-rich inclusions of some carbonaceous chondrite meteorites . This anomalous abundance is attributed to the decay of its parent Al in the inclusions, and researchers conclude that such meteorites were formed in the solar nebula before the Al had decayed. These are among

380-493: A magnesium-based engine . Magnesium also reacts exothermically with most acids such as hydrochloric acid (HCl), producing magnesium chloride and hydrogen gas, similar to the HCl reaction with aluminium, zinc, and many other metals. Although it is difficult to ignite in mass or bulk, magnesium metal will ignite. Magnesium may also be used as an igniter for thermite , a mixture of aluminium and iron oxide powder that ignites only at

475-515: A 1.1-litre engine and from 1983 with a 1.3-litre engine, overdrive top-gear ratio and an early stop-start ignition system (called "SSA"), which would cut the engine when idle for more than two seconds to save fuel whilst temporarily stopped in traffic, and restart the engine on moving the gear lever to the left in neutral. Similar systems were later used on the Volkswagen Golf Mk3 and various systems from other car manufacturers. It

570-508: A 3-door model. The boot space has increased by around 25% from 280 to 351 litres. As an option, this generation introduces the fully digital instrument cluster called "Active Info Digital Display Cockpit", the first car in the small car segment to do so. In addition, the Polo VI introduces a series of driver assistance systems such as traffic sign recognition, blind spot assistant and automatic emergency braking. On 21 April 2021, it will undergo

665-580: A Japanese economy driver, Dr. Miyano, used it to set a new world record for the most frugal circumnavigation of Britain in a standard diesel production car, with an average fuel economy figure of 119.48 mpg or 2.36 L/100 km. In November 2003, Gerhard Plattner covered a distance of 2,910 miles through twenty European countries in a standard Lupo 3L TDI. He achieved his aim of completing this journey, which started in Oslo , Norway, and finished in The Hague in

760-531: A common reservoir. Magnesium is the eighth-most-abundant element in the Earth's crust by mass and tied in seventh place with iron in molarity . It is found in large deposits of magnesite , dolomite , and other minerals , and in mineral waters, where magnesium ion is soluble. Although magnesium is found in more than 60 minerals , only dolomite , magnesite , brucite , carnallite , talc , and olivine are of commercial importance. The Mg cation

855-780: A five-star Euro NCAP crash impact rating. In 2010, a saloon based on the Polo Mk5 platform was developed for launch in India and Russia. This saloon is known as the Vento or Polo Sedan, depending on the country. It has a length of 4,384 mm, increased wheelbase (2,552 mm) and ground clearance (168–170 mm), and had one petrol engine (1.6-litre, four-cylinder, 105 PS; coupled with either five-speed manual or six-speed automatic gearbox) and one diesel engine (1.6-litre, turbocharged four-cylinder common-rail, 105 PS; only five-speed manual gearbox) options available. In several markets, it

950-510: A high purity product is easily achievable. China is almost completely reliant on the silicothermic Pidgeon process . Besides the Pigeon process, the second most used process for magnesium production is electrolysis . This is a two step process. The first step is to prepare feedstock containing magnesium chloride and the second step is to dissociate the compound in electrolytic cells as magnesium metal and chlorine gas . The basic reaction

1045-710: A mid-career facelift. The Volkswagen Polo GTI is a hot hatch version of the Polo. The Volkswagen Polo GTI can trace its roots back to the original hot Polo, the supercharged 1.3-litre 85 kW (115 PS) G40. It was sold in the United Kingdom between 1990 and 1994 in the form of the Mk2F Polo but was available during the late 1980s in limited numbers in Europe in the form of the Mk2 Polo GT G40. The car

1140-456: A multipoint fuel-injected version of the 1272-cc engine, and a top speed more than 100 mph. This produced 75 PS (55 kW) and had a quoted top speed of 172 km/h (107 mph). Times for 0–60 stood at 11.1 seconds. The defining features of the GT include red piping in the bumpers, black overhead cloth, a tachometer, and a red "GT" badge in the grille. This was succeeded by the launch of

1235-420: A relatively slow 0–100 km/h (62 mph) time over 9 seconds, it did have impressive midrange clout with torque figures of 310 Nm (228 lb-ft). Magnesium Magnesium is a chemical element ; it has symbol   Mg and atomic number  12. It is a shiny gray metal having a low density, low melting point and high chemical reactivity. Like the other alkaline earth metals (group 2 of

1330-429: A solid solution with calcium oxide by calcining the mineral dolomite , which is a solid solution of calcium and magnesium carbonates: Reduction occurs at high temperatures with silicon. A ferrosilicon alloy is used rather than pure silicon as it is more economical. The iron component has no bearing on the reaction, having the simplified equation: The calcium oxide combines with silicon as the oxygen scavenger, yielding

1425-535: A true successor to the Volkswagen Golf Mk1 , one of the first true hot hatches . The GTI can be identified by its fully body coloured bumpers and twin central exhausts. In March 2002, a six speed gearbox was added, together with improved throttle response, and was suggested as a competitor to the Mini Cooper , or the larger Volkswagen Polo GTI . The GTI features much more standard equipment which

1520-545: A variety of compounds important to industry and biology, including magnesium carbonate , magnesium chloride , magnesium citrate , magnesium hydroxide (milk of magnesia), magnesium oxide , magnesium sulfate , and magnesium sulfate heptahydrate ( Epsom salts ). As recently as 2020, magnesium hydride was under investigation as a way to store hydrogen. Magnesium has three stable isotopes : Mg , Mg and Mg . All are present in significant amounts in nature (see table of isotopes above). About 79% of Mg

1615-603: A version resembling the original Mk1 shape with a diagonal rear window. The original body style was simply called the Volkswagen Polo without a suffix in most markets ( steilheck , "steep tail" in Germany) while the more traditional design was typically marketed as the Polo Coupé - although in fact, both were three-door hatchbacks. In some markets, the steilheck design was designated a Wagon. The saloon version received

1710-408: A very high temperature. Organomagnesium compounds are widespread in organic chemistry . They are commonly found as Grignard reagents , formed by reaction of magnesium with haloalkanes . Examples of Grignard reagents are phenylmagnesium bromide and ethylmagnesium bromide . The Grignard reagents function as a common nucleophile , attacking the electrophilic group such as the carbon atom that

1805-438: Is Mg . The isotope Mg is radioactive and in the 1950s to 1970s was produced by several nuclear power plants for use in scientific experiments. This isotope has a relatively short half-life (21 hours) and its use was limited by shipping times. The nuclide Mg has found application in isotopic geology , similar to that of aluminium. Mg is a radiogenic daughter product of Al , which has

1900-658: Is a gray-white lightweight metal, two-thirds the density of aluminium. Magnesium has the lowest melting (923 K (650 °C)) and the lowest boiling point (1,363 K (1,090 °C)) of all the alkaline earth metals. Pure polycrystalline magnesium is brittle and easily fractures along shear bands . It becomes much more malleable when alloyed with small amounts of other metals, such as 1% aluminium. The malleability of polycrystalline magnesium can also be significantly improved by reducing its grain size to about 1  μm or less. When finely powdered, magnesium reacts with water to produce hydrogen gas: However, this reaction

1995-486: Is a liquid metal. At the YSZ/liquid metal anode O is oxidized. A layer of graphite borders the liquid metal anode, and at this interface carbon and oxygen react to form carbon monoxide. When silver is used as the liquid metal anode, there is no reductant carbon or hydrogen needed, and only oxygen gas is evolved at the anode. It was reported in 2011 that this method provides a 40% reduction in cost per pound over

2090-585: Is as follows: The temperatures at which this reaction is operated is between 680 and 750 °C. The magnesium chloride can be obtained using the Dow process , a process that mixes sea water and dolomite in a flocculator or by dehydration of magnesium chloride brines. The electrolytic cells are partially submerged in a molten salt electrolyte to which the produced magnesium chloride is added in concentrations between 6-18%. This process does have its share of disadvantages including production of harmful chlorine gas and

2185-773: Is developed on the latest platform, known as the PQ25, the same platform used in the SEAT Ibiza Mk4 that was launched in 2008 and the Audi A1 . The first Polos were hatchbacks, with the saloon being marketed as the Volkswagen Derby. With the release of the Polo Mk2, the saloon was renamed the Volkswagen Polo Classic' and the "conventional"-styled hatchback (with a sloping tailgate) was renamed as

2280-425: Is essential to all cells and some 300 enzymes . Magnesium ions interact with polyphosphate compounds such as ATP , DNA , and RNA . Hundreds of enzymes require magnesium ions to function. Magnesium compounds are used medicinally as common laxatives and antacids (such as milk of magnesia ), and to stabilize abnormal nerve excitation or blood vessel spasm in such conditions as eclampsia . Elemental magnesium

2375-482: Is first treated with lime (calcium oxide) and the precipitated magnesium hydroxide is collected: The hydroxide is then converted to magnesium chloride by treatment with hydrochloric acid and heating of the product to eliminate water: The salt is then electrolyzed in the molten state. At the cathode , the Mg ion is reduced by two electrons to magnesium metal: At the anode , each pair of Cl ions

2470-426: Is less dense than aluminium and is used primarily as a component in strong and lightweight alloys that contain aluminium. In the cosmos , magnesium is produced in large, aging stars by the sequential addition of three helium nuclei to a carbon nucleus. When such stars explode as supernovas , much of the magnesium is expelled into the interstellar medium where it may recycle into new star systems. Magnesium

2565-546: Is more heavily derived from the hatchback body of the Polo, retaining its shorter wheelbase and the rear doors, unlike the larger Vento/Polo Saloon. It was discontinued in 2020 due to low demand. The sixth generation Polo was unveiled on 16 June 2017, with production starting at the Pamplona plant on 17 July 2017. Built on the Volkswagen Group's MQB A0 platform, it is the first generation Polo not to be available as

2660-441: Is much less dramatic than the reactions of the alkali metals with water, because the magnesium hydroxide builds up on the surface of the magnesium metal and inhibits further reaction. The principal property of magnesium metal is its reducing power. One hint is that it tarnishes slightly when exposed to air, although, unlike the heavier alkaline earth metals , an oxygen-free environment is unnecessary for storage because magnesium

2755-401: Is oxidized to chlorine gas, releasing two electrons to complete the circuit: The carbothermic route to magnesium has been recognized as a low energy, yet high productivity path to magnesium extraction. The chemistry is as follows: C + MgO → CO + Mg A disadvantage of this method is that slow cooling the vapour can cause the reaction to quickly revert. To prevent this from happening,

2850-514: Is present within the polar bond of a carbonyl group. A prominent organomagnesium reagent beyond Grignard reagents is magnesium anthracene , which is used as a source of highly active magnesium. The related butadiene -magnesium adduct serves as a source for the butadiene dianion. Complexes of dimagnesium(I) have been observed. The presence of magnesium ions can be detected by the addition of ammonium chloride , ammonium hydroxide and monosodium phosphate to an aqueous or dilute HCl solution of

2945-447: Is protected by a thin layer of oxide that is fairly impermeable and difficult to remove. Direct reaction of magnesium with air or oxygen at ambient pressure forms only the "normal" oxide MgO. However, this oxide may be combined with hydrogen peroxide to form magnesium peroxide , MgO 2 , and at low temperature the peroxide may be further reacted with ozone to form magnesium superoxide Mg(O 2 ) 2 . Magnesium reacts with nitrogen in

3040-758: Is succeeded by the Virtus, while some markets such as Mexico offered the Virtus alongside the Vento for the purpose of keeping a budget-friendly option. In Russia, the Polo Mk5-based Polo Saloon is succeeded by the Škoda Rapid -based Polo liftback. The Ameo is another saloon based on the Polo Mk5 which was released in June 2016. It was specifically developed for the Indian market which offers lower excise tax for vehicles shorter than 4 meter in length. The Ameo

3135-458: Is the eighth most abundant element in the Earth's crust and the fourth most common element in the Earth (after iron , oxygen and silicon ), making up 13% of the planet's mass and a large fraction of the planet's mantle . It is the third most abundant element dissolved in seawater, after sodium and chlorine . This element is the eleventh most abundant element by mass in the human body and

3230-541: Is the second-most-abundant cation in seawater (about 1 ⁄ 8 the mass of sodium ions in a given sample), which makes seawater and sea salt attractive commercial sources for Mg. To extract the magnesium, calcium hydroxide is added to the seawater to precipitate magnesium hydroxide . Magnesium hydroxide ( brucite ) is poorly soluble in water and can be collected by filtration. It reacts with hydrochloric acid to magnesium chloride . From magnesium chloride, electrolysis produces magnesium. World production

3325-655: The G40 in May 1991, displacing the GT as the most powerful Polo at the time, with a top speed around 120 mph – rivalling the likes of the Ford Fiesta XR2i, Peugeot 205 GTI, and Renault Clio 16v . Soon after the launch of the Mark IIF, another sporting model was added to the range — a new version of the supercharged G40, now as a full production model in all markets rather than the limited batch of Mark II G40s. As with

3420-710: The Geneva Motor Show in March 2009. For the first time in Polo's history, the car was declared European Car of the Year , for 2010. The Polo was also declared 2010 World Car of the Year at the New York International Auto Show in April 2010. It also won What Car? Supermini of the Year 2010, as well as being awarded Japan Import Car of the Year for 2010–2011. It shares its platform with

3515-462: The Turkish round. The Super 1600 developed 165 kW (221 hp)/215 to its front wheels. This version of the Polo was a mixed success in the United Kingdom. It sold reasonably well (though not as well as some earlier Polos), but several customer-satisfaction surveys by high-profile motoring magazines such as Top Gear gave the Polo a very low rating. Top Gear' s 2005 survey rated the Polo as

3610-407: The periodic table ) it occurs naturally only in combination with other elements and almost always has an oxidation state of +2. It reacts readily with air to form a thin passivation coating of magnesium oxide that inhibits further corrosion of the metal. The free metal burns with a brilliant-white light. The metal is obtained mainly by electrolysis of magnesium salts obtained from brine . It

It shared its platform with the SEAT Ibiza Mark 2 . This platform actually used the floorpan of the Volkswagen Golf Mk3 (a multitude of mechanical parts and all of

3800-453: The 3L was significantly changed from the standard Lupo to include: The 3L, along with the GTI and FSI, had a completely different steel body to other Lupos, using thinner but stronger steel sheet. The car had an automated manual transmission with a Tiptronic mode on the selector and electro-hydraulic actuation system for the clutch and shifting. The car also had an ECO mode. When engaged it limited

3895-520: The 3L. Early 3L and FSi models had aluminium tailgates which were lighter and more aerodynamic than their standard Lupo counterparts. Early FSi models also had a unique spoiler while later ones without the aluminium tailgates were fitted with the same spoiler as the Lupo GTI. The FSi was only sold in Germany, Austria and Switzerland. The 1.6 L Lupo GTI , introduced in the year 2000, has been labelled

3990-573: The British market never received any diesel-engined versions of the Polo, though the diesel engine was already available on many similar cars by the end of the 1980s, namely the Ford Fiesta, Vauxhall Nova , and Peugeot 205. The Mark II Facelift (referred to as the Mark IIF, also erroneously known as the "Mark 3") was a far-reaching facelift of the MkII, including a reskin of the bodywork, launched in

4085-513: The Fox instead of developing any genuine replacement for the Lupo. The Lupo's spiritual successor, Volkswagen up! , was released in 2011. The Volkswagen Lupo 3L ( Typ 6E ) was a special edition made with the intent of being the world's first car in series production consuming as little as 3 litres of fuel per 100 kilometres (78 miles per US gallon or 94 miles per Imperial gallon). To achieve this,

4180-409: The GTI – available only in three- or five-door hatchback body styles in three colours being red, silver, and black, used a 1.6-litre 16-V 92 kW (125 PS) engine with variable valve timing. External changes included a deeper front splitter with honeycomb mesh grilles, lowered sports suspension (by 10 mm), a subtle rear spoiler, deeper side skirts, fog lights, and 15" BBS RXII split rims for

4275-571: The Italian design studio's contribution restricted to the circular extractor vent cover at the base of the C pillar, and the small "flick-up" at the rear end of the waistline. In 1977, the Derby saloon was released, which was simply a Polo, identical to the hatchback from the C-pillar forward, with a large boot attached. The Mark 1 Polo and Derby were facelifted in 1979 (unofficially referred to as

4370-428: The Lupo 3L with an average consumption of 4.9L/100 km. This direct injection engine next to a conventional engine with similar power uses around 30% less fuel. It had a similar automated gearbox to the 3L but with different gear ratios. Outwardly, it was almost identical to a 3L but with a different front grill, slightly wider wheels with a different design and lacked the magnesium steering wheel and rear bumper of

4465-522: The Lupo 3L, the 3L engine also runs on Rapeseed Methyl Ester (RME) without any changes to the engine. During the period of series production of the Lupo 3L, Volkswagen also presented the 1L Concept , a prototype made with the objective of proving the capability of producing a roadworthy vehicle consuming only 1 litre of fuel per 100 kilometres (235 miles per US gallon). The Lupo FSi was the first direct injection petrol powered production vehicle Volkswagen produced. A 5L/100 km 1.4 16v petrol version of

4560-548: The Lupo is shown below: Volkswagen Polo The Volkswagen Polo is a supermini car ( B-segment ) produced by the German car manufacturer Volkswagen since 1975. It is sold in Europe and other markets worldwide in hatchback , saloon , and estate variants throughout its production run. As of 2018, six separate generations of the Polo have been produced, usually identified by a "Series" or "Mark" number. Some generations were facelifted midway through production, with

4655-457: The Mark 1F) with plastic bumpers, a different front grille, and a revised dashboard. The round headlights of the Derby were replaced with square ones, bringing it in line with the similar Golf-based Jetta saloon. The Polo Mk2 (or Typ 86C ) was introduced in October 1981, with the major change being the introduction of a third body style with a steep (almost vertical) rear window, in addition to

The Lupo 3L shared its engine and special gearbox with the Audi A2 1.2 TDI 3L . As a result of this and other changes, this Audi A2 is also capable of reaching the same results as the Lupo 3L. According to the instruction manual of

4845-514: The Polo being cheaper and much more basic. The two cars were initially sold alongside each other, but the Audi 50 never sold as well, and was withdrawn in 1978. The Polo was manufactured at the Volkswagen plant in Wolfsburg . The manufacturer let it be known that Bertone had been involved in the styling of the Polo and its Audi sibling, although the car was essentially an in-house Audi design, with

4940-540: The Polo hatchback models, with some cosmetic alterations such as new rear and front bumpers and headlights. The Volkswagen Caddy 9K van also shares the same platform and front-end styling as the 6KV models. The later Volkswagen Lupo and SEAT Arosa city cars were based on a shortened version of the Typ 6N platform and shared many components. The Volkswagen Polo Playa was a model for the South African market, where

5035-534: The Polo hatchback. The SEAT Inca and Volkswagen Caddy vans were also based on this model. The Volkswagen Lupo and SEAT Arosa were also based on a shortened version of the Polo Mk3 platform. The Polo Mk4 continued this trend of platform sharing, with the SEAT Ibiza Mk3 and Škoda Fabia Mk1 and Mk2 both being developed on the same platform and featuring several of the same engines. The 2009 Polo Mk5

5130-488: The Polo was shared with other models. The Polo shared its platform with the SEAT Ibiza Mk2. The Ibiza was actually launched before the Polo Mk3 and shared essentially all its mechanicals, the dashboard, and other interior components, although no body panels were shared between the two cars. The saloon and estate versions of the Polo Mk3 were actually rebadged SEAT Córdoba models and had no body panels in common with

5225-518: The SEAT Ibiza Mk3, Škoda Fabia Mk1, and Škoda Fabia Mk2. The car is all new compared to the Mark III/F and bears structural resemblance to Golf MK4 (1J). The rear taillights resemble those of the B5.5 Passat . Outwardly, the most recognisable change is the use of quadruple round headlights similar to the Lupo's. Volkswagen Racing rallied a Polo S1600 in the 2003 Junior World Rally Championships , winning

5320-573: The SEAT Ibiza Mk4 and the Audi A1. Production for the UK market started in August 2009, with first deliveries beginning in October 2009. The Polo Mark V is 44 mm longer, 32 mm wider, and sits 13 mm lower to the road than the previous generation Polo. Boot capacity is increased by 10 L to 280 L of storage space with 952 L with the seats folded down. The car is 7.5% lighter than its predecessor. The Polo has thoracic airbags and has been awarded

5415-742: The SEAT brand was not available. It was sold instead of the European Polo Mark III from 1996 until 2002 and was effectively a rebadged SEAT Ibiza Mark II. In 2002, the Mark IV Polo was adopted in South Africa, and the separate Polo Playa model was dropped. Unveiled in September 2001, the all-new Mark IV (or Typ 9N , sometimes erroneously referred to as the "Mark 4") model was put on sale in early 2002. It shares its platform with

5510-404: The autumn of 1990. The new look had square headlights, enlarged and reshaped taillights, bigger bumpers, and a new interior ( dashboard and door trim). The three different body styles were maintained. Under the skin, the car received modifications to the chassis, suspension, and brakes, as well as the cosmetic differences. The new Polo retained the previous four-cylinder engines, but now as well as

5605-508: The budget E trim and the upgraded S trim; the range later expanded to include a Sport and GTI variant. Petrol engines ranged from 1.0 to 1.4 (1.6 for the GTI) with diesels from 1.2 to 1.7. The differences between the E and S trim included painted door mirrors, door handles and strip, central locking, electric windows, double folding seats and opening rear windows. The Sport also got a chrome centre exhaust and front foglights as standard. The Lupo

The saloon was only produced in Spain, and production ceased in 1992 due to disappointing sales. At the time of launch of the Mark IIF Polo, the highest-performance model was the Polo GT. This featured

5795-573: The corrosion rate of magnesium in a salt solution by a factor of nearly ten. Magnesium's tendency to creep (gradually deform) at high temperatures is greatly reduced by alloying with zinc and rare-earth elements . Flammability is significantly reduced by a small amount of calcium in the alloy. By using rare-earth elements, it may be possible to manufacture magnesium alloys that are able to not catch fire at higher temperatures compared to magnesium's liquidus and in some cases potentially pushing it close to magnesium's boiling point. Magnesium forms

A fuel-efficient two-cylinder diesel was prototyped in the mid-1980s with a G40 supercharger to overcome its small capacity, although this did not enter production. A high fuel-efficiency model that did make production was the petrol-engined Formel E (E for economy), introduced at the launch in 1981 with

6175-494: The launch of the Mk3. The current range includes a variety of three- and four-cylinder petrol and diesel engines. Early versions used a four-speed manual transmission , whilst the current car is available with either six-speed manual or seven-speed automatic transmission . The suspension system on all models uses a fully independent MacPherson strut front suspension, and a twist-beam rear suspension . Most models use disc brakes at

Volkswagen vehicles built on different platforms have carried the Polo nameplate . For example, the Volkswagen Polo Playa hatchback sold in Southern Africa in the late 1990s was a rebadged SEAT Ibiza , which has a different body shell from the Polo Mk3 sold in Europe at

6365-424: The magnesium can be dissolved directly in a suitable metal solvent before reversion starts happening. Rapid quenching of the vapour can also be performed to prevent reversion. A newer process, solid oxide membrane technology, involves the electrolytic reduction of MgO. At the cathode, Mg ion is reduced by two electrons to magnesium metal. The electrolyte is yttria-stabilized zirconia (YSZ). The anode

6840-401: The power to 41 bhp (31 kW; 42 PS) (excluding kick down) and programmed the transmission to change up at the most economical point. ECO mode also activated the start/stop function, a feature that was new to European cars at the time. To restart, the driver simply takes his foot off the brake and presses the accelerator. In ECO mode, the clutch was disengaged when the accelerator pedal

6935-572: The previous model, Volkswagen Motorsport modified G40 Cup cars were sold for racing in a one-make series, the Volkswagen Polo G40 Cup. Features that define the G40 from other Polo models at the time (on top of the GT) include a bee-sting aerial, BBS cross-spoke alloy wheels, Le Mans interior trim, and front and rear red "G40" badges. The Mark III Polo or Typ 6N , (sometimes referred to as

7030-443: The quantity of these metals improves corrosion resistance. Sufficient manganese overcomes the corrosive effects of iron. This requires precise control over composition, increasing costs. Adding a cathodic poison captures atomic hydrogen within the structure of a metal. This prevents the formation of free hydrogen gas, an essential factor of corrosive chemical processes. The addition of about one in three hundred parts arsenic reduces

7125-584: The range were 1.4- (8-valve or 16-valve) and 1.6-litre petrol engines, as well as a 1.9-litre diesel (with or without a turbocharger). The saloon and estate versions of the Mark III, which debuted in 1995, were essentially rebadged version of the SEAT Córdoba , which were launched early in 1994. They were referred to internally by Volkswagen as the Typ 6KV , and shared body panels with the SEAT model rather than

7220-455: The salt. The formation of a white precipitate indicates the presence of magnesium ions. Azo violet dye can also be used, turning deep blue in the presence of an alkaline solution of magnesium salt. The color is due to the adsorption of azo violet by Mg(OH) 2 . As of 2013, magnesium alloys consumption was less than one million tonnes per year, compared with 50 million tonnes of aluminium alloys . Their use has been historically limited by

7315-565: The same time. Starting in 1982, Volkswagen sold the Polo in Japan initially through an agreement with Japanese dealership Yanase that specializes in European and North American vehicles. Of all Volkswagens imported into Japan, only the Polo (until 2017) and the Golf (until 1997), complied with Japanese government dimension regulations until the introduction of the VW Up! in 2012. The first Polo

7410-530: The shores of the Great Salt Lake . In September 2021, China took steps to reduce production of magnesium as a result of a government initiative to reduce energy availability for manufacturing industries, leading to a significant price increase. The Pidgeon process and the Bolzano process are similar. In both, magnesium oxide is the precursor to magnesium metal. The magnesium oxide is produced as

7505-573: The solid state if it is powdered and heated to just below the melting point, forming Magnesium nitride Mg 3 N 2 . Magnesium reacts with water at room temperature, though it reacts much more slowly than calcium, a similar group 2 metal. When submerged in water, hydrogen bubbles form slowly on the surface of the metal; this reaction happens much more rapidly with powdered magnesium. The reaction also occurs faster with higher temperatures (see § Safety precautions ). Magnesium's reversible reaction with water can be harnessed to store energy and run

7600-506: The suspension components were interchangeable among the three models). Although the dashboard and a number of mechanical components, including engines, were shared with the Ibiza, outwardly the two cars were different, with no shared body panels. An all-new 1.0-litre petrol engine was added to the range from launch, while the 1.3-litre petrol engine from the MK2 was briefly carried over. Also new to

7695-403: The tendency of Mg alloys to corrode, creep at high temperatures, and combust. In magnesium alloys, the presence of iron , nickel , copper , or cobalt strongly activates corrosion . In more than trace amounts, these metals precipitate as intermetallic compounds , and the precipitate locales function as active cathodic sites that reduce water, causing the loss of magnesium. Controlling

7790-623: The third-least satisfying supermini to own, with only the Fiat Punto and Rover 25 receiving worse ratings. It fell behind most of its crucial rivals, namely the Ford Fiesta, Vauxhall Corsa , Citroën C3 , and Peugeot 206 . A saloon version of the Mk4 Polo was produced for markets outside Europe, including most Latin American countries, South Africa and China. Volkswagen launched the fifth generation Polo (internal designation Typ 6R ) at

7885-586: The updated versions known unofficially by an addition of the letter F to the mark number, e.g., Mk2F. Some members of the automotive press and some enthusiasts consider the facelifts to be separate models, so have used the unofficial designations Polo Mk1 to Mk7 for previous generations. Each Polo model is also identified by a two- or three-character Volkswagen Group Typ number. Official VW Polo history describes Mark I to Mark IV using either Roman numerals or Arabic numerals , with facelifted variants known as "Phase II" models. The body style has been varied through

7980-510: The very stable calcium silicate. The Mg/Ca ratio of the precursors can be adjusted by the addition of MgO or CaO. The Pidgeon and the Bolzano process differ in the details of the heating and the configuration of the reactor. Both generate gaseous Mg that is condensed and collected. The Pidgeon process dominates the worldwide production. The Pidgeon method is less technologically complex and because of distillation/vapour deposition conditions,

8075-495: The wheels, bearing 195/45/15 tyres. There were also standard extras such as Climatronic fully automatic air conditioning, xenon headlights with a headlight washer system, a six-disc CD autochanger with a GAMMA head unit, exclusive sports interior with leather steering wheel, handbrake and gearstick, chrome inserts, and driver aids such as ABS with EBD and an EDL (a system to aid traction). Leather and satellite navigation were also optional extras. The Polo GTI Mk3F, however, never got

8170-481: Was a rebadged version of the Audi 50 hatchback launched in August 1974. The Audi 50 was discontinued in 1978, as Audi concentrated on larger luxury models. The Mk1 and Mk2 versions of the Polo were then standalone models in the Volkswagen range. With the expansion of the Volkswagen Group : Audi (in the 1960s), SEAT (in the 1980s), and Škoda (in the 1990s) were acquired, and the platform used for

8265-462: Was a popular import in the UK, competing with the likes of the Peugeot 205, Fiat Uno, and Nissan Micra . While of an outdated design, its reliability and build quality were among the best to be found on a small car of this era. In the years since then, it went on to achieve a higher survival rate than many of its competitors. However, some engines were only available on certain markets. For example,

8360-626: Was approximately 1,100 kt in 2017, with the bulk being produced in China (930 kt) and Russia (60 kt). The United States was in the 20th century the major world supplier of this metal, supplying 45% of world production even as recently as 1995. Since the Chinese mastery of the Pidgeon process the US market share is at 7%, with a single US producer left as of 2013: US Magnesium, a Renco Group company located on

8455-610: Was close to larger cars, including the Ford Escort in terms of size, space, and price. Within two years of its launch, however, it was faced with competition from a wave of new rivals, particularly the Fiat Uno and Peugeot 205 . The Polo Mk2 was used extensively by Volkswagen to develop future innovations, for example supercharging with a 40-mm G-Lader supercharger in the GT G40 version. A 60-mm G-Lader would later be used on

8550-465: Was designed by Jozef Kabaň . Sales of the Lupo were slow and missed Volkswagen's targets. In 2001 a Volkswagen source claimed that it was decided the Lupo would eventually be discontinued and replaced by a model built in China. Production of the Lupo was discontinued in June 2005, and was replaced on the European market by the Brazilian designed Fox . Due to the decision taken by Volkswagen, to use

8645-454: Was expensive compared to its rivals of the time, so did not sell in vast numbers. This makes it highly collectible today, and according to Top Gear , "a potential future classic." After production of the G40 ended in 1994, Volkswagen decided to release the first GTI-branded Polo in a limited batch of just 3000. It was released in 1995 and available only in left-hand drive. It featured a 1.6-litre, 16-valve 88 kW (120 PS) engine. The GTI

8740-473: Was not available in the UK at any stage during its limited production, so as of 1994, the UK only had the 75 kW (100 bhp) 1.4-litre, 16-valve as a model with any sporting intent. Between 1999 and 2002, Volkswagen offered two sporting models — the 16V and GTI. The 16V came with the 1.4-litre, 16-valve (V), 74 kW (100 PS) engine, and had options such as 15-in Spa alloys and air conditioning. However,

8835-524: Was not available on any other in the Lupo range, including bi- xenon headlights, 15 inch Bathurst alloy wheels and an off black interior. With a DOHC sixteen valve four cylinder engine producing 125 PS (92 kW), the GTI had a top speed of 127 mph (204 km/h) and could accelerate 0 to 60 mph in 7.8 seconds. More than 480,000 units of the Volkswagen Lupo have been produced through its lifetime. The total production per year of

8930-730: Was released for maximum economy, so the car freewheels as much as possible, with the clutch re engaging as soon as the accelerator pedal or brake pedal is touched. The 3L also has only four-wheel bolts and alloy brake drums at the rear, along with many aluminium suspension components. Initially, there were very few options on the 3L, as options added weight which affected fuel consumption. Those available initially were electrically heated and electrically controlled mirrors, fog lights, and different paint colours. In order to increase sales, other options were offered, including all electric steering, electric windows, and air conditioning. These options, however, increased fuel consumption slightly. In July 2001,

9025-458: Was the most popular in virtually every country where the Polo was sold. Despite the differences in silhouette and target market segment, all body types were two- or three-door only. From the Polo Mk3 onwards, the range was more straightforwardly conventional, including unambiguous "saloon", "hatchback", and "estate" models, with only the hatchback offering both five-door and slightly shorter three-door models (both still with quite vertical tailgates,
