VW's DSG shifts up a gear

2008-01-09 07:42
Volkswagen's pioneering DSG twin-clutch gearbox makes its debut in revised form this year, now equipped with seven gears and a few innovative tricks thrown in for good measure.

Described by the manufacturer a being "revolutionary", the new transversely mounted seven-speed DSG gearbox adopts a pair or dry clutches rather than the existing oil-immersed system.

This is said to significantly reduce weight, while improving the efficiency of the system and making the gearbox more compact.

Lower gears are more closely spaced, so in-gear acceleration is improved and overtaking is easier, while taller high gears reduce engine load and increase fuel economy.

The seven-speed transmission is designed to operate under "moderate power and torque loadings" and will be offered in addition to the current six-speed DSG.

And while VWSA told Wheels24 that "there are no plans as yet to bring the seven-speed DSG to South Africa", the new gearbox should filter through the local line-up in due time.
