Volkswagen’s new seven-speed gearbox
Volkswagen will be welcoming the new year with new innovative components, just like its DSG twin-clutch gearbox that will feature “seven gears, greater efficiency and a more compact design”. According to the report of The Auto Channel, this new gearbox will make its debut in the new year.
Offered as an add on, this seven-speed DSG gearbox is far better than the already impressive six-speed DSG gearbox, since it wick use a pair of dry clutches rather than a pair of wet clutches in oil. The report said that this will make the gearbox more compact, along with saving weight and boosting the efficiency of the system.
The new seven-speed DSG system will be available in connection with the new 1.4-litre TSI 122 PS engine, once it is launched. It is designed “to operate under moderate power and torque loadings.”
Volkswagen also claims that the gearbox can lessen 10 g/km of CO2 in a Golf hatchback, as it brings it down from 149 g/km in the manual to 139. It will also get better fuel economy of over 3 mpg. “It is also possible to combine this gearbox with the 1.9-litre TDI diesel unit with Diesel Particulate Filter.”
Along with economical benefits, performance will also improve with the new seven-speed DSG system. “The lower gears are more closely spaced, meaning in-gear acceleration is improved to aid overtaking maneuvers, while the higher gears are lengthened to reduce loading on the engine and maximize economy.” It will also have a hill-hold function that will help the vehicles when it is starting on an incline.
UK will be first to see and experience the new seven-speed gearbox once it debut in February. Orders are now being taken in various Volkswagen Retailer and prices will start at £15,982 when applied to the Golf S 1.4-litre TSI 122 PS.
