Volkswagen's plan of making compact cars more fuel efficient by utilizing a 10-speed dual clutch gearbox has just been delayed indefinitely.

According to Motoring AU, sources closes to the matter stated that the fuel-saving transmission proved to be too complex and expensive for the automaker. One of the sources even said that the company had to balance out which priorities should be met and are considered more urgent that the 10-speed DSG.

First developed back in 2013 for the 34th International Vienna Motor Symposium, the now shelved 10-speed gearbox was originally meant to be mated with a high performance diesel engine that will be able to deliver 136 PS per liter of displacement.

Apart from this, the 10-speed DSG would have also been used on the Golf and Polo nameplates, as well as other inline-three and inline-four models from Audi, Seat and Skoda. Rated to handle up to 500 Nm of torque, the axed DSG can also be connected to either FWD or RWD models.

Currently, Volkswagen's highest dual clutch gearbox count is at seven and can be found on certain models like the new Beetle and other concept vehicles.
