The Volkswagen Beetle – officially the Volkswagen Type 1, informally in Germany the Käfer (German, "beetle") and in parts of the English-speaking world the Bug – is a two-door, four-passenger, rear-engine economy car that was manufactured and marketed by German automaker Volkswagen (VW) from 1938 until 2003
The need for this kind of car, and its functional objectives, was formulated by the leader of Nazi Germany, Adolf Hitler, who wanted a cheap, simple car to be mass-produced for his country's new road network. Hitler contracted Ferdinand Porsche in 1934 to design and build it.[12] Porsche and his team took until 1938 to finalise the design. The influence on Porsche's design of other contemporary cars, such as the Tatra V570 and the work of Josef Ganz remains a subject of dispute. The result was one of the first rear-engined cars since the Brass Era. With 21,529,464 produced,[13] the Beetle is the longest-running and most-manufactured car of a single platform ever made.
Although designed in the 1930s, the Beetle was only produced in significant numbers from 1945 on (mass production had been put on hold during the Second World War) when the model was internally designated the Volkswagen Type 1, and marketed simply as the Volkswagen (or "People's Car"). Later models were designated Volkswagen 1200, 1300, 1500, 1302 or 1303, the former three indicating engine displacement, the latter two derived from the type number. The model became widely known in its home country as the Käfer (German for "beetle") and was later marketed as such in Germany,[4] and as the Volkswagen in other countries. For example, in France it was known as the Coccinelle (French for ladybug)
The original 25 hp Beetle was designed for a top speed around 100 km/h (62 mph), which would be a viable speed on the Reichsautobahn system. As Autobahn speeds increased in the postwar years, its output was boosted to 36, then 40 hp, the configuration that lasted through 1966 and became the "classic" Volkswagen motor. The Beetle ultimately gave rise to variants, including the Karmann Ghia, Type 2 and external coach builders. The Beetle marked a significant trend, led by Volkswagen, Fiat, and Renault, whereby the rear-engine, rear-wheel-drive layout increased from 2.6 percent of continental Western Europe's car production in 1946 to 26.6 percent in 1956.[14] The 1948 Citroën 2CV and other European models marked a later trend to front-wheel drive in the European small-car market, a trend that would come to dominate that market. In 1974, Volkswagen's own front-wheel drive Golf model succeeded the Beetle. In 1994, Volkswagen unveiled the Concept One, a "retro"-themed concept car with a resemblance to the original Beetle, and in 1998 introduced the "New Beetle", built on the contemporary Golf platform with styling recalling the original Type 1. It remained in production through 2010, being succeeded in 2011 by the more aggressively styled Beetle
Design
Illustration of the Beetle's engine air cooling and exhaust systems
The Beetle featured a rear-located, rear-wheel drive, air-cooled four-cylinder, boxer engine in a two-door bodywork featuring a flat front windscreen, accommodating four passengers and providing luggage storage under the front bonnet and behind the rear seat – and offering a coefficient of drag of 0.41; to this relatively good CD, the also streamlined rear of car was of help. The bodywork attached with eighteen bolts to its nearly flat chassis which featured a central structural tunnel. Front and rear suspension featured torsion bars along with front stabilizer bar – providing independent suspension at all wheels. Certain initial features were subsequently revised, including mechanical drum brakes, split-window rear windows, mechanical direction-indicators and the non-synchronized gearbox. Other features, including its distinctive overall shape, endured. In fact, the Beetle was prized for its seemingly unchanged appearance and "marketed to American consumers as the anti-GM and Ford: 'We do not believe in planned obsolescence. We don't change a car for the sake of change.'"[46]
Its engine, transmission, and cylinder heads were constructed of light alloy. An engine oil cooler (located in the engine fan's shroud) ensured optimal engine operating temperature and long engine life, optimized by a thermostat that bypassed the oil cooler when the engine was cold. Later models of the carburetor featured an automatic choke. Engine intake air passed through a metallic filter, while heavier particles were captured by an oil bath. After 1960, steering featured a hydraulic damper that absorbed steering irregularities.
Indicative of the car's utilitarian design, the interior featured painted metal surfaces, a metal dash consolidating instruments in a single, circular binnacle, adjustable front seats, a fold-down rear seat, optional swing-out rear windows, front windows with pivoting vent windows, heating via air-to-air exchange manifolds operating off the engine's heat, and a windshield washer system that eschewed the complexity and cost of an additional electric pump and instead received its pressurization from the car's spare tire (located in the front luggage compartment) which was accordingly overinflated to accommodate the washer function.
Throughout its production, VW marketed the Beetle with a four-speed manual transmission. From 1961 (and almost exclusively in Europe),[47] VW offered an optional version of the Saxomat semi-automatic transmission: a regular 4-speed manual transaxle coupled to an electromagnetic clutch with a centrifugal clutch used for idle. Subsequently, (beginning in 1967 in Europe and 1968 in the United States), VW offered an optional semi-automatic transmission (marketed as Automatic Stick Shift and also called AutoStick[citation needed]), which was a 3-speed manual coupled to an electro-pneumatic clutch and torque converter.
While the overall appearance of the Beetle changed little over its life span, it received over 78,000 incremental changes during its production.
Evolution and design changes
Beetle cabriolet[edit]
1960 VW 1200 Cabriolet
It was in 1948 that Wilhelm Karmann first bought a VW Beetle sedan and converted it into a four-seated convertible. The Beetle Cabriolet began production in 1949 by Karmann in Osnabrück. After successfully presenting it at VW in Wolfsburg, production started in 1949.
The convertible was more than a Beetle with a folding top. To compensate for the strength lost in removing the roof, the sills were reinforced with welded U-channel rails, a transverse beam was fitted below the front edge of the rear seat cushion, and the side cowl-panels below the instrument panel were double-wall. In addition, the lower corners of the door apertures had welded-in curved gussets, and the doors had secondary alignment wedges at the B-pillar.
The top was cabriolet-style with a full inner headliner hiding the folding mechanism and crossbars. In between the two top layers was 1 in (25 mm) of insulation. The rear window was tempered safety glass, and after 1968, heated. Due to the thickness of the top, it remained quite tall when folded. To enable the driver to see over the lowered top, the inside rearview was mounted on an offset pivot. By twisting the mirror 180 degrees on a longitudinal axis, the mirror glass would raise approximately 2 in (5.1 cm).
The convertible was generally more lavishly equipped than the sedan with dual rear ashtrays, twin map pockets, a visor vanity mirror on the passenger side, rear stone shields, and through 1969, wheel trim rings. Many of these items did not become available on other Beetles until the advent of the optional "L" (Luxus) Package of 1970.
