1. 9 litre 4-cylinder 90hp (A3 type) - used in various models sold until approximately 1998 in Europe and North America. Within this document we will call this the A3 engine even though it was also used in other models, because the most popular cars sold with this engine were the A3-chassis Golf, Jetta, and Vento sold from 1994 until early 1999. Not all model years were available in all markets, and this engine was replaced by the newer type (here called the A4 type) gradually over a period of years. Other models sold with this engine include the B4 Passat (1995 - 1997), VW Sharan minivan, and various Audi models.
