The first VW Polo I was from the spring of 1975 produced until mid-1981 three-door compact car with hatchback from Volkswagen. 

History

The name Polo was borrowed from the sport of the same name and was supposed to make a reference to the VW Golf. On September 10, 1974, the name Polo was decided in a board meeting for the new model. Other suggested names at that time were Bonito, Euros, Mini-Golf and Pony.  Under the name Bonito had since 1969 been the Fiberfab FT Bonito, and 1975 brought the Hyundai Motor Company to Hyundai Pony on the market.

In March 1975 series production began in the Wolfsburg plant, on March 13, 1975, the Polo was first shown to the public at the Geneva Motor Show. In May 1975, the first vehicles were delivered to customers. 

The first model bears the in-house designation Type 86. The Polo was only available as a three-door hatchback in the features Basis, L, S, LS, LX, CLS, GLS, GT and Formula E. In addition, a notchback variant was offered from February 1977 under the name VW Derby.

The basic version was initially very sparse. The door panels were made of cardboard, on the passenger side missing the locking cylinder of the door lock, the door contact of the interior lighting, the sun visor and the upper handle. From the beginning there was a trim level Polo L, which was almost identical in appearance to the Audi 50. When it became clear that Audi should stop operating the small car segment, the Polo was gradually upgraded. The better-equipped Polo GLS appeared in August 1978. Equipment: all models are 2-door Saloons with wide, up- swinging tailgate; combined ventilation/heating system with infinitely variable fresh and warm air mixture; blower (2-speed on L model) makes the system independent of engine; heat taken from cooling system; through-flow ventilation extractor vents in left and right side panels of luggage compartment.

VW Polo I (1975-1981) Maintenance

In February 1979 there was a facelift, which included the grille and the bumpers (now made of plastic). The dashboard has also been redesigned, provided with a wooden imitation strip and received a filing box. In addition, the 60 hp Polo GT was brought to market.

By the early 1980s in January 1981, the fuel-efficient version of Formula E with 3 + E transmission came on the market, but already in June 1981, the Polo I was discontinued.
