I-Shift is Volvo's most advanced solution for changing gears. It combines the simplicity of an automatic transmission with the effciency of a perfectly automated 12-speed gearbox. This means additional comfort for the driver and a fuel saving of up to 7 percent for the operator.
HOW SMART IS IT?
Firstly, it knows exactly how to get maximum performance out of each Volvo engine using in-depth knowledge about their unique characteristics. Secondly, it monitors the vehicle mass, its resistance including road inclination, speed and acceleration – then uses the data to predict and select the ultimate gear for optimal effciency. If needed, it even skips one or more gears.
Like the best driver in the world, it does this in real time. And it does it all the time. In this way I-Shift reduces fuel consumption by up to 7 percent compared with a manual gearbox.
I-SHIFT WITH I-ROLL
Saving up to 2 percent fuel when in use, I-Roll uses the kinetic energy of the truck's motion to reduce fuel consumption when driving in top gear. On moderate hills it disengages the engine allowing the vehicle to roll out for longer distances, delaying the need to inject more fuel.
Weighing 70 kg less than its manual counterpart, the transmission itself increases the possible cargo weight of the truck, improving the economic opportunities in turn. Economy is also improved by the smooth shifting, which puts less stress on the driveline and tyres – extending the lifecycle of parts and minimising maintenance costs. And the fact that it makes less noise reduces wear and tear on the driver.
