Volvo Trucks – The Flying Passenger: How it works

This test was set up to demonstrate
how a Volvo FH can keep up its speed on hilly and curvy roads
and still save fuel. A professional paraglider
was attached to the truck by a wire. To keep the paraglider flying, the truck had to maintain speed
even when driving up steep inclines. It also had to accelerate
out of the bends quickly and smoothly, with no dip in torque, otherwise the paraglider
would lose too much altitude. Maintaining speed
is very important for our customers because you can save
total driving time of your mission at the same
as you reduce fuel consumption. The key to success
is Volvo Trucks’ unique powertrain that combines exceptional performance
with optimal fuel efficiency. The engine and the gearbox are matched to communicate and work together
in the best possible way. The I-Shift Dual Clutch
plays an important role in the test. It’s the world’s first
dual clutch gearbox for heavy trucks. The main purpose when we developed
the dual clutch gearbox was to have a smooth gear shift
without power loss. With the Volvo gearbox,
you can stay in high gears at low rpm which leads to saving fuel. The main innovation with the dual clutch
is that you have two gearboxes in one. When you’re driving,
the next gear is already preselected and then you shift very smoothly. The heart of the powertrain
is the enhanced D13 engine, now with common rail injection, increased compression ratio
on the 420 and 460 horsepower versions, a new optimised turbo
on the 500 and 540 horsepower versions and a large number of improvements which will lower
the engine’s internal friction, changes which all make a big difference, saving fuel
without sacrificing performance. When you drive a truck
with a dual clutch, first of all you feel
how convenient it is. It’s a very smooth and quiet ride. What we talk about here
is very technical, but the best way to experience it
is to actually drive it.
