Polestar is slowly unveiling details of its first car, Polestar 1 sporty sedan. One of the key components in creating a responsive and agile driving experience is also a carbon fibre reinforced polymer CRFP, which lead to hefty weight savings.

Carbon fibre body also represents the first time that the Volvo Car Group has explored carbon fibre construction, but it took its job very seriously, because the Polestar Production Center, which is due to begin production in 2019, is being specifically tooled for carbon fibre construction.

Most of the main body parts will be constructed from light CRFP, which will lead to an overall weight savings of 230 kilograms. Body parts, constructed from CRFP, will include bonnet, boot lid, side panels, doors and the entire roof structure. Also the dragonfly shaped component, which radically improves torsional stiffness of critical joint between the middle of the floor and rear construction, will be made from carbon fibre.

"When you combine this strengthened framework with the super-strong body and roof structure, you get a stiff and communicative chassis which translates driver input into superb driving characteristics," said Christian Samson, Head of Product Creation at Polestar.

Not just structure but also the design will benefit from the use of carbon fibre. The carbon fibre roof will be thinner and stronger than steel one and it will also allow lower roof line for a more sleek profile of Polestar 1.
