Our smartest gearbox


A new way to drive

I-Shift Dual Clutch is the world’s first dual clutch transmission system for heavy trucks, offering really smooth, dynamic acceleration. Inspired by motor racing gearboxes, I-Shift Dual Clutch changes gear in a fraction of a second. It produces a steady flow of power that will transform the way you drive – and boost productivity.

How I-SHIFT with Dual Clutch works

Driver comfort and safety

If your assignments demand high performance and frequent gear changes, choose I-Shift Dual Clutch. It provides unrivalled driver comfort. The torque is constant, so you can confidently change gear in the middle of a bend. And the power is transferred continually to the wheels, meaning a minimal risk of getting stuck or losing your grip in slippery conditions. Even when engine-braking downhill with down shifting, you can be sure of a firm and safe ride. I-Shift Dual Clutch is available for our 500 and 540 hp D13C engines.

What the dual clutch adds

The dual-clutch transmission can pre-select the next gear while driving in the current one. So, one clutch is idling while the other is engaged. Thanks to two input shafts and an ingenious arrangement of gearwheels and selecting elements, two gears can then be selected at the same time. The result? Gear shifting that takes place in a fraction of a second - without interrupting the power delivery.
