VW Beetle 1951

The 1951 VW Bug or VW Beetle Split window has an unique design. The split window in the back is timeless and it provides the 1951 Beetle with a very high value. It was very easo to spot a 1951 VW Beetle Split Window model, just look for the ventilation flaps on the body panel between the front fender and the door. This was one of at least 25 significant running changes. In January, the generator pulley was redesigned, a sleeve for guiding the accelerator cable return spring was added and the original magnesium-aluminum alloy crankcase was replaced by the electron type experimented with earlier. Volkswagen also decided to bench test the Standard Beetle Sedan rather than run it in on a test track. A synthetic cam gear was put into production and the exhaust silencer pipe was modified. Windows appeared in both halves of the crankcase starting in April. A Wolfsburg crest was added on the front hood of the Export VW Beetle 1951 Split Window model. Also, the front heater flaps were moved inside the heat exchangers and telescopic shocks relaced the lever-action style on export models and convertibles. Bright metal trim was added to the windshield of export Beetle models, the front side panels got pull-out flaps and a locking glove compartment was addet to the Beetle Convertible.
