The power train also provides ample evidence of Volkswagen's technological leadership. The keyword here is direct fuel injection. Taking the TDI diesel engines as an example, the supreme new power unit in this area is the 2.0 TDI, which develops 103 kW (140 PS). It is a high-torque four-cylinder unit with four valves per cylinder, driving the wheels through a new six-speed gearbox or with the option of the direct-shift gearbox (also with six speeds). Volkswagen was the first manufacturer worldwide to introduce this type of gearbox, in its Golf R32 DSG model. Then there are the FSI engines: this abbreviation is used for the units with direct petrol injection. The 1.6 FSI, rated at 85 kW (115 PS), has already proved successful in the Touran and is now to be available in the Golf. Here too, a six-speed gearbox is standard equipment, but the driver can, as an optional extra, leave the gear changes to a smooth, efficient six-sped automatic transmission. The new Golf will be launched with a choice of four power units - two petrol engines (55 kW / 75 PS and the 1.6 FSI with an output of 85 kW (115 PS), and two TDI diesels (77 kW / 105 PS or 103 kW / 140 PS). All Golf engines comply with the EU 4 exhaust emission standard. Four further engines will be launched slightly later, including two FSI units and an SDI diesel. In due course, additional engine options at the top end of the power-output scale will also become available. Delivery of cars with the automatic transmission and DSG options will start early in 2004.
