The new Polestar 1 PHEV – the first car from Volvo’s now standalone performance brand – will make extensive use of CFRP to save weight and add stiffness.
Of course, the Polestar 1 is more than just an S90 Coupe, with its plug-in hybrid powertrain delivering almost 600bhp and an EV range of pushing on for 100 miles (officially, at least), it offers much more performance than any ordinary Volvo. And it looks great.
But the price you pay for an electric or plug-in powertrain is the additional weight, so Polestar are making extensive use of Carbon Fibre Reinforced Polymer (CFRP) in the Polestar 1 to mitigate that weight gain and add stiffness, and the ability to offer more ‘style’ too.
The extensive us of CFRP does go some way to explaining the high price of the Polestar 1, with CFRP used for the bonnet, boot, side panels, doors and roof structure, as well as for a ‘Dragonfly’ to improve torsional stiffness between the middle of the floor and the back end. And it all adds up to a weight saving of 230kg.
Thomas Ingenlath, Polestar CEO, said:
Carbon fibre is crucial in meeting our design, engineering and performance goals with the Polestar 1. The result is a beautiful, technological package that remains faithful to the original design with its elegant and low silhouette. It looks as good as it is to drive!
All sounds good. But £135k is still steep – even with lots of carbon fibre.
