Mito and Giulietta to get twin-clutch auto gearbox from later this year

Alfa Romeo will introduce a new twin-clutch TCT auto gearbox on the Mito late this year and the Giulietta in spring 2011.

The six-speed design, developed in-house by Fiat, employs dry clutches and has a torque capacity of 188lb ft, just enough to cope with the Giulietta Cloverleaf's 177lb ft 1.7 turbo on overboost.

Initially it will only be fitted to the 135bhp 1.4 Mito and the 170bhp 1.4 petrol and 2.0 diesel Giuliettas.

DCT are patented by Borg-Warner/Volkswagen

Surely its only the DSG monica thats patented and maybe some of the engineering? Otherwise it would be like patenting the 6 speed manual?

No confusion, just Autocar doing their usual due diligence:
"Fiat Powertrain Technologies’ new transmission can transmit torque of 350 Nm and comes in both six-gear manual and Dry Dual Clutch versions." - Source, FIAT press release at http://www.fptpowertrain.com/eng/pdf/press_release.pdf
For those still living in the 19th century, 350 Nm is 260 lb ft, not 188. The 2.0 litre diesel's peak torque is limited to 350 Nm in the Giulietta so that it can use this gearbox.
Maybe I should become an auto journalist. It seems you don't even need to do research anymore...
The principle of a dual clutch transmission is not new and is widely understood. Only BorgWarner's implementation of the idea would attract a royalty payment, so if Ford or FIAT or anyone else produced a design not covered by those patents, they'd be fine.

Good find KrisW, you should try becoming a reporter it seems they will need a few at Autocar shortly.
