The fourth generation of Volkswagen Jetta is known as the A4. Introduced in 1999, the A4 Jetta was known as the Bora in most parts of the world except for North America and South Africa. This new generation of Jettas was available either as a sedan or as a station wagon. The A4 was available with inline 4 or VR6 engines, and also saw the introduction of a VR5 engine. While the fifth generation A5 Jetta was introduced in 2006, some A4 models remained in production until 2007 as more entry level variants.
