Smarter than your average gearbox
No heavy clutch. And no lever to wrestle. I-Shift is also available on all Volvo FMX models with a driven front axle. And has been reinforced for the most challenging terrain. So now you can tackle rough and hilly terrain with the comfort and fuel-efficiency of our most popular transmission.
I-Shift makes driving easier, safer and much more comfortable. There’s no load on your body. Every gear change is perfectly timed. And if you want to change gear manually, there’s a button on the gearstick that gives you full control over every shift.
Driveability isn’t the only benefit. The smoothness of the system puts less stress on the driveline and tyres, minimising maintenance costs.
Save on fuel
I-Shift is designed to save fuel – up to 5%. The internal energy losses are low – lower than on manual gearboxes. But it’s the electronics that really make the difference. If you drive in Economy mode, every gear change is timed precisely, ensuring the engine works at the most efficient rpm.
How it works
I-Shift is based on an unsynchronised manual gearbox –hence the compact design and low internal losses. The magic, however, happens in the electronic control unit that manages the clutch and shifts. By evaluating information about speed, weight, road grade and torque demand, it performs every shift with extreme precision. The system also communicates with the engine, allowing it to adjust revs and brake-effect for maximum performance.
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.
Basic Shift Strategy
Automatic selection of the right starting ratio (1st – 6th gear). The choice of starting gear is influenced by gross weight and road gradient.
Gives faster and gentler changes through intelligent utilisation of the engine brake, the vehicle’s clutch and a special transmission brake.
Basic Gear Selection Adjustment
Makes it possible to adjust gear selection via the gear lever’s buttons during engine braking in automatic mode.
Gearbox Oil Temperature Monitor
Shows the gearbox oil’s temperature in the information display.
Enhanced Shift Strategy
Maximises the VEB/VEB+ braking effect by automatically selecting the right gear, so that the engine operates at high revs. When changing gear during engine braking, the wheel brakes are activated to compensate for loss of braking torque.
Optimises gear selection for manoeuvring at low speeds. Among other things, this also ensures that the Hill Start Aid function is only activated on uphill gradients.
Automatic engagement and disengagement of a freewheel function for the purpose of reducing fuel consumption. I-Roll is used when neither engine power nor engine braking is needed: on flat roads, for instance.
Smart Cruise Control
Interacts with the vehicle’s Brake Cruise and ensures that the auxiliary brakes are not activated unnecessarily. The free-wheel function can thus be utilised to an even greater extent.
Heavy Duty GCW control
Optimises gear selection for high gross combination weights, 85–180 tonnes.
Enhanced Gear Selection Adjustment including kick-down
Makes it possible to adjust gear selection via the gear lever’s buttons during start and when driving in automatic mode. The kick-down function selects the right gear for maximum acceleration.
Enhanced performance – Bad roads
Several functions that adjust gearchanging and assist starting and driving in poor road conditions and hilly terrain.
