The gearbox is best known as Volkswagen group’s DSG (Dual Shift Gearbox)-branded unit.
The DualTronic technology enables a conventional-looking gearbox to function as a fully automatic transmission by eliminating the ‘torque-interrupt’ feeling that occurs when a manual transmission shifts gears, while delivering performance and fuel economy that rival that of a manual transmission. Billed as DSG, the technology made its debut on the VW Golf R32 DSG and Audi TT 3.2 in 2003, and is now found in a number of VW Group vehicles.
“This advanced technology will be first applied in China in our new [Rover 75-based] SAIC Roewe 750,” said Yang Chunbao, Shanghai Automotive Industry Co. Ltd. and president, Shanghai Automobile Gear Works. “This is our first project with BorgWarner and we look forward to more co-operation in the future.”
BorgWarner will develop and provide five production modules, which include the dual clutch, the torsional vibration damper, the hydraulic controls with shift actuation, the synchronizers and the hydraulic pump. The transmission assembly will be jointly developed by SAGW and GIF, a German engineering company. Transmission assembly production will be conducted at SAGW in China.
The original Rover 75, on which the Roewe 750 is based, used conventional five-speed automatic gearboxes made by Jatco.
