Volvo FH on the road in the forest

Our smartest gearbox - now even smarter

The most advanced transmission system on the market is now available in an even smarter version:for really smooth, dynamic acceleration.

Volvo FH16 with I-Shift Dual Clutch on the road

Just drive

I-Shift makes driving easier, safer and more comfortable. There’s no heavy clutch, and no stick to wrestle with. Every gear change is perfectly timed. The simplicity of the system reduces driver fatigue, helping you to focus on the road and the traffic around you. And if you do want to change gear manually, the button on the gearstick gives you direct control of the shift.

How it works

How it works

I-Shift is based on a "classic" unsynchronised manual gearbox – hence its compact design and low internal losses. The magic happens in the electronic control unit that manages the clutch and shifts. By evaluating information about speed, weight, road grade and torque demand, it applies extreme precision to every shift. The system also communicates with the engine, allowing it to adjust the revs and brakes for best performance.

Reinforced for severe duty applications

Reinforced for severe duty applications

If you drive in extremely tough conditions, you will appreciate the reinforced I-Shift. It has been designed exclusively for environ­ments where you frequently climb or descend gradients of above 10%, or drive in extremely rough terrain. This means that I-Shift is now available for conditions where a manual gearbox or the automatic Powertronic used to be the only options.

Reduced fuel consumption

Crawl slow, run lean

Can I-Shift with crawler gears really help boost your fuel economy? Sure. Because previously, you often had to be willing to sacrifice fuel economy for startability. But thanks to the crawler gears, we can now specify your truck with a faster rear axle ratio, allowing you to stay on cruising speed at much lower revs when you’re driving on decent roads. This lowers your fuel consumption by up to a couple of percent.

Perfect control at very low speeds

Perfect control in any direction

Low-speed manoeuvring is one of the most challenging aspects of the job. Thanks to a transmission ratio of up to 32:1 (and up to 37:1 in reverse), I-Shift with crawler gears let’s you drive at speeds as low as 0.5-2 km/h. You always have total control, making it easy to park with precision when you’re about to load or unload your cargo, and to avoid accidents that can ruin your day and your productivity.

Adds to the versatility of the truck

Say yes to more jobs.

I-Shift with crawler gears adds to the versatility of the truck, letting you use the same truck for a host of different driving conditions and assignments. Drive both on-road and off-road? Need to transport extreme loads? Work at high altitudes? Special low-speed applications? No problem. The crawler gear module only adds 120 mm to the length and 48 kg to the weight of I-Shift.

Save on fuel

I-Shift is designed to save fuel. The internal energy losses are lower than on manual gearboxes, but it’s the electronics that really make the difference. Every gear change is timed precisely. This ensures that the engine works at its most efficient rpm, whether in economy or performance mode. 
Additionally, when you're travelling downhill, I-Roll disengages the engine - maximising the truck’s momentum and saving additional fuel.

Unrivalled driver comfort and safety

If your assignments demand high performance and frequent gear changes, I-Shift 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 is available for our D13C and D16G engines.
