Though it hardly changed outside, the 1960-1969 Volkswagen Beetle kept getting better under the skin, and became a reassuring presence in the mad, mod world of the 1960s.
Americans took to the Volkswagen Beetle in ever larger numbers, both as practical, no-frills transportation and for a quirky charm that perfectly suited the era's "Up the Establishment" mood -- an unassuming David against Detroit's gas-guzzling Goliaths. Yet even as "Beetlemania" reigned supreme, the times were changing faster than the car. How much longer could it last?
Design overview
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 Cx or coefficient of drag of 0.41. 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 and rear stabilizer bars – providing independent suspensions 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.
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 simple, no-nonsense 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.
While the overall appearance of the Beetle changed little over its life span, it received over 78,000 incremental changes during its production
Development
Initially designated the Porsche Type 60 by Ferdinand Porsche, the design team included Erwin Komenda and Karl Rabe. In October 1935 the first two Type 60 prototypes, known as the V1 and V2 (V for Versuchswagen, or "test car"), were ready. In 1936, testing of three further V3 prototypes, built in Porsche's Stuttgart shop,began. A batch of thirty W30 development models, produced for Porsche by Daimler-Benz, underwent 1,800,000 mi (2,900,000 km) of further testing in 1937. All cars already had the distinctive round shape and the air-cooled, rear-mounted engine. Included in this batch was a rollback soft top called the Cabrio Limousine. A further batch of 44 VW38 pre-production cars produced in 1938 introduced split rear windows; both the split window and the dash were retained on production Type 1s until 1953. The VW38 cars were followed by another batch of 50 VW39 cars, completed in July 1939.
The car was designed to be as simple as possible mechanically, so that there was less to go wrong; the aircooled 25 hp (19 kW) 995 cc (60.7 cu in) motors proved especially effective in actions of the German Afrika Korps in Africa's desert heat. This was due to the built-in oil cooler and the superior performance of the flat-4 engine configuration. The suspension design used compact torsion bars instead of coil or leaf springs. The Beetle is nearly airtight and will float for a few minutes on water.
The Volkswagen was officially named the KdF-Wagen by Hitler when the project was officially announced in 1938. The name refers to Kraft durch Freude ('Strength Through Joy'), the official leisure organization of the Third Reich. The model village of Stadt des KdF-Wagens was created near Fallersleben in Lower Saxony in 1938 for the benefit of the workers at the newly-built factory. After World War II, it was known as the Volkswagen Type 1, but became more commonly known as the Beetle.
