Fiat Group Automobiles has announced that they will unveil its first dual-clutch gearbox in September 2009. The gearbox will be designed and built by Fiat Powertrain Technologies at an investment of 500 million euros. The new gearbox called the DDC will be able to handle up to 343Nm of torque. The dual clutch transmission is one of three transmission variants in the C635 family. The other two will be a manual and a single clutch automated manual.
The new dual clutch Fiat Powertrain Technologies C635 gearbox will use two dry clutches (DDC means Dual Dry Clutch) which are lighter and require less cooling than wet clutches, but there is no indication at the moment how many speeds the gearbox would have, though 6-speed is the most likely since the C635 family will feature a manual as well, and I don’t think a 7-speed manual is very common,
