In a stunt set up by Volvo to demonstrate the precision control of its new trucks, a young woman has walked a slackline between two trucks driving at full speed.

It’s a stunt never before attempted and one that even stunned the Hollywood director of the film now available on YouTube.

The woman on the line is American slackliner Faith Dickey. She is the world record-holder in highlining, a young sport which is all about walking on a line as high and far as possible.  “I'm used to heights, long lines and lines that sway in the wind. But those lines are firmly anchored to cliff-faces. Walking a line attached to two moving points is something quite different," she said.

Peter Pedrero, who normally works with stunts in films such as James Bond, Harry Potter and Pirates of the Caribbean, said he was dumbstruck when he heard about the idea.  "And here was I thinking that every imaginable stunt had already been done. The fact is that nobody has ever before walked a line between two moving trucks. It felt like an enormous challenge, and it's challenges that get me going,"

The film's director, Oscar-nominated Henry Alex Rubin, was also encouraged by the difficulty of the filming. "My favourite kind of shoot is when someone tells me something is impossible to film. When I hear no, it makes me want to move mountains," he said.

The force behind the film is Volvo Trucks and the aim is to highlight the driveability and superior handling of the company's latest truck model, the new Volvo FH. The stunt was possible to carry out due to the excellent stability and handling of the new Volvo FH, and thanks to this stability both trucks could maintain a steady gap throughout the stunt.

"It's not enough simply to say that we are good. We wanted to demonstrate just how much progress we've made in the area of driveability and handling," said Ulf Nordqvist, Project Manager for the new Volvo FH series. The world premiere and official launch of the Volvo FH Series was held on September 5, 2012.
