New VW TSI Engine and 7-Speed DSG

Market launch second half 2007
Volkswagen is continuing its drive train offensive. At the International Vienna Engine Symposium (26 - 27 April), Europe's largest car maker presented its new TSI petrol engine (90 kW / 122 PS) and the world's first seven-speed dual clutch gearbox (DSG) for the compact and mid-class. Both products are scheduled for market launch in the second half of the year.
TSI stands for maximum power coupled with minimum consumption by combining direct injection and turbo-charging with reduced engine capacity. The award-winning TSI engines with a power output of 103 kW and 125 kW are popular choices, for example for the Golf and Touran. The new 90 kW TSI will be the third option in the TSI engine line-up.
With 200 Newton metres of torque at 1,500 rpm, the torque of the current 1.4-liter turbo engine is almost 30 percent higher than the torque of the 1.6 FSI engine. The TSI has low-end torque gains of up to 66 percent. In spite of the improved performance and torque characteristics, consumption has been reduced by approximately six percent. Technically, the new TSI is based on its compressor counterparts with 103 and 125 kW. In contrast to twin-charged engines, the "small" 90 kW TSI uses just the turbo-charger for boost - an additional compressor is not required.
World's first seven-speed DSG gearbox for volume models
A further innovation is the seven-speed DSG gearbox. In contrast to the six-speed DSG gearbox, the clutches of the new gearbox do not run in an oil bath. This further improves efficiency. Volkswagen's six-speed DSG gearbox gave automatics sensationally low consumption figures. Thanks to this efficiency and sporty shifting characteristics, the DSG provoked a boom in the popularity of DSG gearboxes in the compact and mid-class. For example, the DSG is ordered in 25 percent of Tourans today. The new seven-speed DSG gearbox has added an attractive option to the Volkswagen range. It will be available for vehicles from the Polo to the Passat. The transferable maximum torque is equivalent to a maximum of 250 Newton metres.
The combination of the two new products results in excellent consumption figures and convenience, comfort and driving enjoyment. In the Golf, it has a fuel consumption of just 5.9 l/100 km. Both the seven-speed DSG gearbox and the 90 kW TSI show once again that Volkswagen makes highly innovative technology available to all drivers.
