The EA827 family of petrol engines was initially developed by Audi under Ludwig Kraus leadership and introduced in 1972 by the B1-series Audi 80, and went on to power many Volkswagen Group models. This is a very robust water-cooled engine configuration for four- up to eight- cylinders. In Brazil this engine was produced under the name Volkswagen AP AP.

The Audi 80 is a compact executive car produced by the Audi subdivision of the Volkswagen Group across four generations from 1966 to 1996. It shared its platform with the Volkswagen Passat from 1973 to 1986 and was available as a saloon, and station wagon — the latter marketed by Audi as the Avant. The coupé and convertible models were not badged as members of the range, but used a derivative of the same platforms.
