Mercedes-Benz M180 Engine
The Mercedes Benz M180 Engine was a single overhead camshaft inline-6 cylinder engine introduced at the Frankfurt Motor Show in April 1951 to power the company's new 220 (W187). It was the first engine with a cylinder bore greater than its stroke that Mercedes had installed in a production car, while using a reverse-flow cylinder head . It spawned four variants through 1968, the final and largest being the 2.8 L M130. It was achieved by boring out and stroking the M180's original "over-square" bore × stroke of to , yielding a displacement of . Mercedes also unveiled at the 1951 Frankfurt Motor show a larger 3.0-litre M186 ‘big six’ inline-6 to power its new flagship 300 (W186) ''Adenauer'' four-door saloon. While sharing many design features such as staggered valve arrangement and rockers running off a single overhead camshaft driven by a duplex cam-chain, the engines were of completely different design with little or no inter-changeability of parts.''Six Appeal'', Mer ...

Mercedes-Benz W113
: ''See Mercedes-Benz SL-Class for a complete overview of all SL-Class models.'' The Mercedes-Benz W 113 is a two-seat roadster/coupé, introduced at the 1963 Geneva Motor Show, and produced from 1963 through 1971. It replaced both the 300 SL ( W 198) and the 190 SL ( W 121 BII). Of the 48,912 W 113 SLs produced, 19,440 were sold in the US. The W 113 SL was developed under the auspices of Mercedes-Benz Technical Director Fritz Nallinger, Chief Engineer Rudolf Uhlenhaut and Head of Styling Friedrich Geiger. The lead designers were Paul Bracq and Béla Barényi, who created its patented, slightly concave hardtop, which inspired the "Pagoda" nickname. All models were equipped with an inline-six cylinder engine with multi-port fuel injection. The bonnet, boot lid, door skins and tonneau cover were made of aluminum to reduce weight. The comparatively short and wide chassis, combined with an excellent suspension, powerful brakes and radial tires gave the ...

Mercedes-Benz W187
The Mercedes-Benz W187 is a luxury car produced by Mercedes-Benz from 1951 to 1955. Introduced at the Frankfurt Motor Show in April 1951, the W187 was powered by a single overhead camshaft inline six-cylinder M180 engine and available as a saloon, coupé, and cabriolet, all designated with the 220 model name. Despite its pre-World War II reputation as a manufacturer of luxury cars, in the immediate post-war years Mercedes-Benz produced only four-cylinder-engined passenger cars. The W187 Mercedes-Benz 220 and flagship W186 Mercedes-Benz 300 ''Adenauer'' introduced together in 1951 were the first Mercedes to once again feature six-cylinder engines. History Models The styling was similar to that of the Mercedes-Benz 170S except that the 170's freestanding headlights were for the 220 integrated into the fenders for a slightly more modern look. Two different cabriolet models were built, conceived as exclusive sporting cars of exclusive character, but these only sold 1,278 and 997 ...

Mechanical Fuel Injection
Fuel injection is the introduction of fuel in an internal combustion engine, most commonly automotive engines, by the means of an injector. This article focuses on fuel injection in reciprocating piston and Wankel rotary engines. All compression-ignition engines (e.g. diesel engines), and many spark-ignition engines (i.e. petrol engines, such as Otto or Wankel), use fuel injection of one kind or another. Mass-produced diesel engines for passenger cars (such as the Mercedes-Benz OM 138) became available in the late 1930s and early 1940s, being the first fuel-injected engines for passenger car use. In passenger car petrol engines, fuel injection was introduced in the early 1950s and gradually gained prevalence until it had largely replaced carburettors by the early 1990s. The primary difference between carburetion and fuel injection is that fuel injection atomizes the fuel through a small nozzle under high pressure, while a carburettor relies on suction created by intake air ...

Ponton (automobile)
Ponton or pontoon styling is an automotive design genre that spanned roughly from the 1930s-1960s, when pontoon-like bodywork enclosed the full width and uninterrupted length of a car body — eliminating previously distinct running boards and articulated fenders. The integrated fenders of an automobile with ponton styling may also be called ''Pontoon fenders,'' and the overall trend may also be known as ''envelope styling.'' Now largely archaic, the term ''Ponton'' describes the markedly bulbous, slab-sided configuration of postwar European cars, including those of Mercedes-Benz, Opel, Auto Union, DKW, Borgward, Lancia, Fiat, Rover, Renault, and Volvo—as well as similar designs from North America and Japan, sometimes — in its most exaggerated usage — called the "bathtub" look in the U.S. The term derives from the French and German word ''ponton'', meaning 'pontoon'. The Langenscheidt German–English dictionary defines ''Pontonkarrosserie'' as "all-envelopi ...

Unimog
The Unimog (, ) is a range of multi-purpose tractors, trucks and lorries that has been produced by Boehringer from 1948 until 1951, and by Daimler Truck (formerly Daimler-Benz, DaimlerChrysler and Daimler AG) since 1951. In the United States and Canada, the Unimog was sold as the Freightliner Unimog. Unimog production started in 1948 at in Göppingen. Daimler-Benz took over manufacture of the Unimog in 1951, and first produced it in their Gaggenau plant. From 1951, the Unimog was sold under the Mercedes-Benz brand. However, the first Unimog to feature the three-pointed Mercedes-Benz star was only introduced in 1953. Since 2002, the Unimog has been built in the Mercedes-Benz truck plant in Wörth am Rhein in Germany. The Mercedes-Benz Türk A.Ş. plant assembles Unimogs in Aksaray, Turkey. Unimogs were also built in Argentina (first ever country to do so outside Germany) by Mercedes-Benz Argentina S.A. under licence from 1968 until 1983 (with some extra units built until 1991 o ...

Unimog 404
The Unimog 404, also called the Unimog S and Unimog 404 S, is a vehicle of the Unimog-series by Mercedes-Benz, produced in the Unimog plant in Gaggenau from 1955 to 1980. Marketed as ''Unimog U82'', and later ''Unimog U110'', 64,242 units of the two Unimog 404 types ''404.0'' and ''404.1'' were built, which makes the 404 the Unimog model with the highest production figure of all Unimogs. Unlike the Unimog 401, the 404 is rather a small 1.5-tonne-offroad-truck than an agricultural vehicle. In Germany, it was a common military vehicle and fire engine, 36,000 Unimog 404 were made for the Bundeswehr. The first Unimog 404 concept-vehicle was made in 1953 and was slightly smaller than the series production model, it had a track width of and a wheelbase of . Two prototypes for the French army followed in 1954, the first 1,100 series production models were also purchased by the French army. Since the French army did not want the spare wheel to occupy space for soldiers on the bed, the D ...

Mercedes-Benz W105
The Mercedes-Benz W105 is the internal designation for a four-door executive car, manufactured by Daimler-Benz from 1956 to 1959, and marketed as the Mercedes-Benz Typ(e) 219. The W105 was nicknamed ''Ponton'', along with its Mercedes model siblings, from its introduction, because it employed ''Ponton'', or pontoon styling, a defining post-war car design innovation that unified a car's previously articulated bonnet, wings, body and running boards into a singular, slab-sided envelope. The Mercedes 219 (internally W105), had a 2.2 L inline 6-cylinder engine, and uniquely featured a bodyshell that combined the stretched nose of the more luxury W128 and W180 models 220a and 220 S(E), but shared the regular standard wheelbase cabine, with shorter rear doors, with the 1953 entry-level 4-cylinder Mercedes W120/W121 models 180 and 190, to offer an intermediate no-frills 6-cylinder model option. History The body shape had been introduced in 1953 by the W120 chassis 180. I ...

Convertible (car)
A convertible or cabriolet () is a passenger car that can be driven with or without a roof in place. The methods of retracting and storing the roof vary among eras and manufacturers. A convertible car's design allows an open-air driving experience, with the ability to provide a roof when required. A potential drawback of convertibles is their reduced structural rigidity (requiring significant engineering and modification to counteract the effects of removing a car's roof). The majority of convertible roofs are of a folding construction framework with the actual top made from cloth or other fabric. Other types of convertible roofs include retractable hardtops (often constructed from metal or plastic) and detachable hardtops (where a metal or plastic roof is manually removed and often stored in the trunk). Terminology Other terms for convertibles include cabriolet, cabrio, drop top, drophead coupé, open two-seater, open top, rag top, soft top, spider, and spyder. Consistenc ...

Coupé
A coupe or coupé (, ) is a passenger car with a sloping or truncated rear roofline and two doors. The term ''coupé'' was first applied to horse-drawn carriages for two passengers without rear-facing seats. It comes from the French past participle of ''couper'', "cut". __TOC__ Etymology and pronunciation () is based on the past participle of the French verb ("to cut") and thus indicates a car which has been "cut" or made shorter than standard. It was first applied to horse-drawn carriages for two passengers without rear-facing seats. These or ("clipped carriages") were eventually clipped to .. There are two common pronunciations in English: * () – the anglicized version of the French pronunciation of ''coupé''. * () – as a spelling pronunciation when the word is written without an accent. This is the usual pronunciation and spelling in the United States, with the pronunciation entering American vernacular no later than 1936 and featuring in the Beach Boys' hi ...

Sedan (car)
A sedan or saloon (British English) is a passenger car in a three-box configuration with separate compartments for an engine, passengers, and cargo. The first recorded use of the word "sedan" in reference to an automobile body occurred in 1912. The name derives from the 17th-century litter known as a sedan chair, a one-person enclosed box with windows and carried by porters. Variations of the sedan style include the close-coupled sedan, club sedan, convertible sedan, fastback sedan, hardtop sedan, notchback sedan, and sedanet/sedanette. Definition A sedan () is a car with a closed body (i.e. a fixed metal roof) with the engine, passengers, and cargo in separate compartments. This broad definition does not differentiate sedans from various other car body styles, but in practice, the typical characteristics of sedans are: * a B-pillar (between the front and rear windows) that supports the roof * two rows of seats * a three-box design with the engine at the front and the car ...

Mercedes-Benz W186
The Mercedes-Benz W186 Model 300 was a four-door luxury sedan produced by Mercedes-Benz between 1951 and 1957. It was the company's flagship model at the time, succeeding the World War II era W150. Three versions were produced in succession, known informally as the 300a (or simply 300), 300b, and 300c. An enlarged "300d" variant built on the W189 chassis succeeded it in late 1957. Also referred to as a "Type 300", the W186 was equal in features and price but superior in performance to the rival Rolls-Royce Silver CloudClassic and Sportscar Magazine, February 1994, Pp. 52-55 and Bentley S1. Favored by statesmen and business leaders, it offered options such as a glass partition, VHF mobile telephone, and dictation machine. The W186 is often identified as an Adenauer after Konrad Adenauer, the first Chancellor of the Federal Republic of Germany (West Germany), who employed six custom cabriolet, hardtop saloon, and landaulet versions of the W186 and its successor W189 during his ...
