“Small on the outside. Big on the inside.” This was the slogan used by Volkswagen 50 years ago to advertise its latest product at the time, the Polo. When the small car came on the market in early May 1975, nobody expected that the extremely compact two-door vehicle would become a bestseller – nationally and internationally, over five decades, in six generations, with several prestigious awards, with more than 20 million units sold and as a pioneer in the compact car segment.
