VW sells one millionth DSG, next million on the way
1 million DSG – Volkswagen celebrates the bestselling gearbox
Kassel has produced the dual-clutch gearbox for the Group since 2003
Latest 7-speed DSG now available
Wolfsburg/Kassel, 05 February 2008 – DSG – three letters that stand for supreme shift comfort, economy and sportiness. Together with staff from the Kassel factory and Prof. Werner Neubauer, member of the Board of Management of the Volkswagen brand responsible for the Components division, the management of the Volkswagen factory in Kassel today celebrated the one-millionth dual-clutch gearbox (DSG).
The idea for the dual-clutch gearbox was born in motor-racing. It was picked up by Volkswagen in the 1980s and has since been developed further. When the first Volkswagen DSG went into series production in 2003, it sent shockwaves through professional circles. This innovation provided a previously unknown level of shift comfort. The once clear line between automatic and manual gearboxes had been bridged, and an extraordinary level of driving dynamics achieved.
Even the customers were soon enthusing, despite all the reservation compared to conventional gearboxes. Just five years later, the DSG has, for example, a 25 percent installation rate on the Touran. This is also a major success for the staff at the Kassel factory, the only Volkswagen factory to produce the DSG.
In 2007 alone, more than 400,000 six-speed DSG gearboxes were installed across the Group – and there is no sign of an end to this success story. “Because of the great demand, we shall shortly be boosting our daily capacity to 1,750 units,” explained General Factory Manager Dr. Hans-Helmut Becker.
Prof. Werner Neubauer added: “All around the world, our DSG gearboxes from Kassel are synonymous with sporty driving pleasure and economical fuel consumption. They successfully combine the best of two gearbox worlds. We are already on the way to the two-millionth DSG, and on the way, this modern technology will sharpen Volkswagen’s global competitive edge in the field of transmission technology even further.”
Jürgen Stumpf, Chairman of the Works Council at the VW factory in Kassel is also convinced by the DSG: “The competence and expertise of our staff make this cutting edge technology ‘made by Kassel’ possible. The DSG has now become a guarantee for job security at the factory.”
Volkswagen has now shifted up a gear with the new 7-speed dual-clutch gearbox, the second generation of the successful bestseller. This gearbox combines two world firsts. Firstly, it is the first 7-speed DSG for front-traverse installation. Secondly, it is the first with clutches that are not immersed in oil, but which run “dry”. This enables the latest Volkswagen DSG, available in the Golf, Golf Plus, Cross Golf, Golf Variant, Polo, Cross Polo and other models to achieve even greater efficiency.
New 7 Speed DSG
28th January, 2008
Five years ago Volkswagen presented the first production dual-clutch transmission in the world: the 6-speed DSG. An intelligent automatic, a transmission of superlatives. The winning move of dual clutch transmissions had begun at Volkswagen.
Since then over one million 6-speed DSGs have been sold! In just the first eleven months of last year 364,000 were sold. This is now being followed up by another transmission sensation: the world’s first 7-speed DSG to be produced in high-volume. For many car drivers this could signify the final turn away from conventional transmissions. Because the new DSG can do everything better than a manual gearbox. It is more fuel efficient, sporty and comfortable.
DSG for the “small” high-volume engines
The new 7-speed DSG makes the revolutionary transmission technology available for smaller engines too, engines that develop up to 250 Newton-meter torque. The 7-speed DSG will be initially introduced on the Golf, Golf Variant and Golf Plus paired with the latest TSI (90 kW / 122 PS) and the bestselling TDI (77 kW / 105 PS) of the model series.
New “dry” dual clutch improves efficiency
The most prominent component of the DSG is its dual clutch. In comparison to the 6-speed DSG, there is no “wet” clutch in the new transmission that is a clutch immersed in an oil bath rather a “dry” clutch. That too is a world first for DSG technology. This and other engineering modifications led to significant improvements to the DSG’s efficiency. The result: Further reduced fuel consumption and emissions values, even greater convenience and driving fun.
The 122 PS TSI in the Golf consumes just 5.9 liters/100 km with DSG. A record
A look at the fuel economy and driving performance data of the Golf, with and without 7-speed DSG, underscores the progress made. This much can be said right away: The new 122-PS TSI on the Golf is a masterpiece of fuel efficiency. Shifted by a manual 6-speed gearbox, the charged gasoline engine in the Golf consumes just 6.3 liters of fuel per 100 kilometers and this is even less than that of models with lower PS output. However, when the same Golf TSI is paired with the new 7-speed DSG, average fuel consumption (95 ROZ octane Super) is reduced even further: to just 5.9 liters. Similarly, CO2 emissions are reduced from 149 g/km to 139 g/km. These are data that just a short while ago would have been considered inconceivable for a gasoline engine in this performance class. Especially for an automatic: Compared to a conventional automatic with torque converter, the new DSG even consumes up to 20 percent less fuel!
DSG market share up to 28 percent. Trend is upward
Since the 7-speed DSG can now also serve on smaller engines, another jump in volume can be expected for DSG. In the final months of 2007, the DSG share in the Golf class even without 7-speed DSG already rose to above nine percent. The year’s average for the new Golf Variant came in at over ten percent. On the Golf Plus the average for 2007 was greater than twelve percent. The Jetta had a DSG share of over 13 percent, and the Eos over 14 percent. 24 percent of all Touran buyers chose a dual-clutch transmission in the past year. It was about 22 percent on the Passat sedan and over 28 on the Passat Variant. The trend toward automatics when they have DSG is therefore clearly evident.
Before production start the new DSG covered two million test kilometers
Both DSGs are built at the VW Transmission Plant in Kassel. The light 70 kilogram 7-speed DSG is built with about 400 parts. The new transmission is like an old friend to employees in Kassel as production volume is being ramped up these days: as early as September 2005 a die-casting machine was used to produce the first prototype case. While the many DSGs had to prove their qualities on stationary test benches for far more than 60,000 hours of durability testing, developers sent the other DSG prototypes aboard Golf and Co. to run test trial routes in the real world. They covered about two million kilometers. Afterwards the findings were clear: the new DSG is extremely durable and extremely efficient too.
Pilot production started in November 2007 in Kassel
In the last week of November 2007, series production of the new DSG was finally started. Plans already call for increasing output up to 750 7-speed DSGs per day over the course of this year. If demand rises even more, production could be ramped up to 1,500 7-speed DSGs per day by implementing a second assembly line. In parallel, 1,500 units of the 6-speed DSG are being produced daily in Kassel. Demand is booming!
