The Mk. II Volkswagen Golf and Jetta range of models was introduced in March 1984, revised body and trim features being the main visual difference to the earlier range of models. The engine/transmission is mounted transversely at the front of the vehicle, drive being to the front wheels. Detailed improvements have been made throughout the years of manufacture to improve power output and economy. These include the introduction of hydraulic bucket tappets, the Digifant, Digijet and Mono-Jetronic fuel injection systems, the 16-valve engine fitted to the GTi variant, the fully electronic ignition system (FEI), the 085 5-speed gearbox and several other minor modifications and revisions. As with earlier models the new range is proving popular, giving economy, reliability, comfort and, if previous models can be used as a yardstick, long life.
