Inspired by the racing world, the new I-Shift Dual Clutch sets a new standard in drivability. It’s the first time a heavy goods vehicle has used gearbox technology of its kind. “The feeling is just magic,’ says Björn Lyngsö project manager for I-Shift Dual Clutch. ‘The power is there the whole time.’
With a double clutch transmission you can change gears much faster. The clutches work in parallel, where one gear is always engaged. “It’s like having two I-Shift gearboxes to change between in a fraction of a second. When you start driving in first gear on one, second gear is already in place on the other,” explains Björn Lyngsö. “It simply flows, softly and quietly.”
Volvo’s Transmission team has built on the technology developed for the renowned I-Shift. “This time they’ve taken it a step further adding totally unique features to create a new transmission. Giving you added drivability, comfort and the means to power-shift. The design is very compact with only 120mm added, and the fuel economy hasn’t been compromised either. It’s on par with the I-Shift,” says Astrid Drewsen, Product Manager Driveline.
When you join this innovation with Volvo’s most powerful D13, Euro 6 engine, “then you get a really good combination,” explains Astrid Drewsen. “From low revs it produces 2600Nm of torque, and steadily transfers this down to the wheels. In every situation.”
Enjoy the Drive
This steady flow of power and torque give you a smoother ride downhill, up hill or whatever the terrain. “The I-Shift Dual Clutch chooses the smartest and most efficient way to change gears. It can jump gears to be economical. Then when you need it, it power-shifts. This is very quick and smooth, almost seamless. Giving you uninterrupted power,” says Astrid Drewsen.
“There’s no problem with gear changes in the middle of a bend – the pull is there the whole time. One of the test drivers likened it with the drive wheels locking on to the road with suction,” adds Björn Lyngsö.
Traction and acceleration have also improved, even with a heavy load at red lights and roundabouts. “You gain speed quickly, and then it’s easy to maintain a steady speed the whole way even if there are lots of hills. This means increased productivity,” says Björn Lyngsö.
Happy Driver. Happy Truck
In difficult situations, uphill and wet forest terrain you can relax. "The power is delivered right down to the wheels, at every moment, minimizing the risk of slipping or loosing traction. Something that otherwise could be a stressful safety concern to the driver. Instead, with I-Shift Dual Clutch the driver can relax, be in control and comfortable even in these situations," says Astrid Drewsen.
By choosing the smartest way to shift gears, it also helps to reduce overall stress on the truck. "It's gentle towards the driveline and vehicle. Giving you less wear and tear to the truck," adds Astrid Drewsen.
