Yes and no...blurb from autospies...

The twin/dual clutch gearbox was invented by Andolphe Kégresse in the late 1930s.

Known as the "Transmission autoserve Kégresse" it was intended for the legendary Citroen Traction Avant.
However, due to circumstances, it never made into the Traction Avant.
After improvements it was presented at the 1947 Salon de Paris on a Citroen 11 CV.

After more than 45 years since Andolphe Kégresse first created it, Porsche had the PDK twin-clutch put into their endurance racers. This PDK gearbox was also used by Audi in their some of their rally cars.

Today BorgWarner is currently the leading manufacturer of this type of transmission.

They are most commonly sold under the name Direct-Shift Gearbox, as sold by Volkswagen Group.
