In 1981, the MP4/1 acronym for the F1 McLarens designated “Marlboro Project Four” and indicated the origins of the project in the team's official sponsor. Carbon fiber was used extensively, especially for the body, which was very light and rigid. The rest of the car, however, was quite conventional, with the classic Ford Cosworth DFV engine, awaiting the development of the new Tag-Porsche turbo engine. The car proved to be competitive already in 1981, then in 1982-1983 with the various MP4/1B and MP4/1C-D-E updates.
The Danhausen company of Aachen, Germany, began producing its own series of handcrafted 1:43 models under the names Metal 43, Plumbies, SD Models and Minichamps in 1974. Between 1976 and 1990, AMR produced over 70 different Minichamps models for Danhausen. The mass production of highly detailed die-cast model cars, marketed under the name Minichamps, began in China in 1990 and marked a real revolution in the field of model making, with high quality products at extremely competitive prices. Minichamps models are developed in Germany, but production and assembly takes place in the Far East. In less than ten years Minichamps practically became the reference in the diecast sector. In 2004 the first resin miniatures were introduced. Over the years other scales have been developed significantly, including 1:18. The Maxichamps range, which includes affordable reissues of older Minichamps items, was introduced in 2016.
