Chapter 1: Crash Test
The Polestar 1 is tested in every conceivable condition and
environment. These cars are optimized for snow, rain, blistering heat, arctic
cold, and every road surface imaginable. The Polestar 1 will provide a peerless
driver experience under any circumstances, and the testing process is designed
to make that a certainty.
It’s not enough to only test for the predictable, however.
It’s also imperative to test for the unpredictable. Accidents aren’t planned,
but they can be planned for. And plan for them we do, by putting the
verification prototype cars through crash tests at different speeds and various
angles. It’s dramatic. It’s exhilarating. And it’s necessary.
Polestar evaluates strength of carbon fibre in successful
first crash test
Polestar has undertaken the first of a series of crash
tests as part of the development of the Polestar 1. This represents the first
time the Volvo Car Group has assessed the strength of a carbon fibre reinforced
polymer body in a real crash situation.
“We were really excited about this crash test. The first
crash test of Polestar 1 has been about exploring the unknown,” says Thomas
Ingenlath, Chief Executive Officer at Polestar. “This was a crucial proof point
in the development of Polestar 1; we had to know that the ideas and
calculations that have gone into building this car were right – and they were.”
In contrast to a steel body where bending helps the
integrated crumple zones to reduce the amount of crash energy that reaches the
vehicle’s occupants, carbon fibre dissipates energy by cracking and shattering.
Close attention was given to the way the carbon fibre body
reacted to the extreme forces involved in the impact. The engineers also
focused on how the underlying steel body structure, and carbon fibre
‘dragonfly’ which strengthens it, managed the forces.
The Polestar 1 verification prototype, part of the first
Polestar 1 build series, was propelled into a stationary barrier at 56 km/h,
simulating a frontal collision.
Most of the energy was absorbed by the car’s crash
structure, with the remaining energy mitigated by the carbon fibre body panels
into the body structure which remained rigid and did not show signs of bending
or misalignment after the crash.
Zef van der Putten, responsible for carbon fibre at
Polestar, comments: “The outcome of this first crash test validates the
decision to build the body of Polestar 1 in carbon fibre. It also confirms that
carbon fibre supports the highest safety standards. This is an example of how
Polestar spearheads the development of new technology in the Volvo Car Group.”
The crash test was conducted at the Volvo Cars Safety Centre
in Gothenburg, Sweden, where cars and other vehicles are crash-tested in a
large number of real world simulations.
