Volkswagen, Europe's largest car maker, showed its new TSI petrol engine (90 kW / 122 PS) along with the world's first seven-speed dual clutch gearbox (DSG) for the compact and mid-class. These products were presented at the International Vienna Engine Symposium in April 26-27 and will be launched in the half of 2007. These products are Volkswagen's way of continuing its drive train offensive.

TSI means maximum power accompanied with minimal consumption. This is done by mixing direct injection and turbo charging with minimal engine capacity.

The Golf and Touran can use these TSI engines, which has a power output of 103 and 125 kilowatts. The third option in the engine line-up is the new 90 kilowatts TSI.

The torque of the current 1.4 liter turbo engine is estimated 30 percent higher than the torque of the 1.6 FSI engine. The current turbo engine has 200 Newton-meters of torque at 1,500 rpm.

The TSI engine can have low-end torque gains of up to 66 percent. Consumption has been diminished by approximately 6 percent, in spite of refined performance, better VW timing parts, and improved torque characteristics.

The new VW TSI engine is patterned on its compressor counterparts that have 103 and 125 kilowatts. As differentiate to twin-charged engines, the 90 kilowatts TSI maximizes just the turbo-charger for boost, where an added compressor is not a requirement.

Meanwhile, VW has also introduced the first ever seven-speed DSG gearbox. This is another first from the German automaker. This gearbox will be used for volume models.

As compared to the six-speed DSG gearbox, the seven-speed DSG's clutches further improves efficacy. The VW six-speed DSG gearbox gave automatic engines small amount of consumption. With the efficacy and sporty attributes, the DSG made the DSG gear boxes well known in the compact and mid class type of vehicles. A very concrete example is the DSG being ordered in almost 25 of Tourans in the market today.
