Talk:Twin-clutch Gearbox

The article says "This type of gearbox was invented by Andolphe Kégresse just before the outbreak of World War II, but he never developed a working model." I believe that the gearbox used in the Citroen Traction Avant was the of the twin-clutch gearbox design, I quote from the following web site: [1] says: " In the year 1933, Citroën had need of a totally new model despite all its financial problems. It would be a revolutionary automobile. The features wanted in the new model included the following: 100 km/h maximum speed, a consumption of 10 litres / 100 km, uni-body construction, front-wheel drive, and automatic gearbox. To realize these plans, Citroën engaged André Lefèbvre as engineer for the project. Flamino Bertoni was responsible for the design of the car (no relationship to Nuccio Bertone , who also does contract work for Citroën).

The first prototypes were soon prepared and ready for testing. The automatic gearbox showed many problems, but the rest of the car seemed fine. Within three weeks, a new manual gearbox was designed, with three forward and one reverse gear. "

Kegresse of course designed the Citroen Kegresse half-track a design he started while working for the Czar of Russia.
