How Volvo’s Making the Polestar 1 From an Previous Idea

The nice tragedy of the Idea Coupe was that it was by no means meant to be constructed. Drawing on the model of the classic P1800 with a serving to of American muscle—wholesome haunches, slim home windows—the two-door gained a lot reward when Volvo introduced it to the 2013 Frankfurt Motor Present. It was beautiful, however not more than a showcase. Followers must accept seeing parts of the design feed into Volvo merchandise just like the XC90 SUV and S90 sedan.

Then the automobile world shifted. Governments began clamoring for electrical autos, Tesla proved expertise might be a promoting level, and Volvo relaunched its performance-oriented Polestar marque as an efficiency EV model. It determined the Idea Coupe, with its electrical hybrid drivetrain and horny appears, could be the proper automobile to kick begin its new line, because the Polestar 1.

Right now, Sofia Björnesson, venture chief for the Polestar 1, is understanding the small print on making that occur. “Nothing was done with it until two years ago, when it was decided to make a production version of the car,” she says.

For Björnesson and her staff, that meant working quick. Polestar unveiled the ultimate design for the automobile on the Geneva Auto Present in March, and is because of present the automobile operating for the primary time on the Goodwood Pageant of Pace within the UK subsequent month.

Working quick, and dealing laborious. Constructing a one-off demo car with a low roofline and shrunken wheelbase is straightforward if you will by no means need to get it licensed or into mass manufacturing. Doing it with a automobile that should carry out and deal with properly, one that may benefit a guaranty and that may be assembled at affordable value is, properly, trickier. The automobile is a sporty hybrid, combining a traditional inside combustion engine to drive the entrance wheels, and electrical motors on the again. However getting the utmost electric-only vary of round 100 miles, earlier than the gasoline engine has to kick on to maintain transferring, means squeezing out each ounce, notably because the 34-kWh batteries bump up the bottom weight.

“To create the beautiful lines in the body shape of this car, you need something other than steel,” Björnsson says says. “So we looked at carbon fiber, to see if that can do the task for us.” Carbon fiber, a favourite of Method 1 groups and supercar builders, permits designers rather more flexibility, as a result of it may be molded into deep creases and dramatic shapes in a approach that conventional metal stamping cannot replicate. Even higher, its far lighter. “It’s more perfect from a design freedom, but a harder material to work in,” she says.

The design staff’s choice to make use of carbon fiber within the physique in addition to the doorways and the hood makes for a automobile that is 500 kilos lighter than it might be in the event that they used metal. The one little bit of the old-school materials is the floorpan, which comes from the Volvo S90 sedan, chopped down in size. However even that half depends on a cross-shaped little bit of carbon fiber that reinforces a weak spot between the automobile’s mid and rear sections. “We call it the dragonfly,” says Björnesson. “It makes the ground a lot stiffer than we anticipated.” Checks present a 45 p.c improve in torsional stiffness within the chassis, a stunning quantity for anybody involved about dealing with and cornering.


The staff additionally learnt find out how to correctly render the carbon fiber they’re utilizing in laptop fashions, so they might check its power in several instructions, underneath totally different circumstances. They’re assured that the weaves within the fiber at the moment are positioned in the appropriate instructions within the automobile, to make each bit as sturdy as attainable. Plus, the fabric permits for a sleeker look. Due to its power, they might decrease the roof and make the pillars holding it up much less cumbersome.

None of this comes low-cost. The automobile will promote for $155,000 within the US, placing it someplace above Audi’s R8, however under a McLaren 570S. It is one thing of a daring transfer for a newly revived model, however it will not be the final. Polestar has already dedicated to constructing at the very least two extra autos, the primary of which will probably be a smaller, cheaper, sedan (be careful, Tesla Mannequin 3). That will rely much less on carbon fiber, to maintain the value decrease.

These new expertise in translating unfeasible ideas into manufacturing prepared autos ought to encourage automobile followers clamoring for the opposite ideas Volvo has proven, however claims it will not construct, together with the two-door wagon Idea Property and the XC SUV coupe designed for surfers and their ilk. Polestar has achieved it as soon as in any case. Hopefully Björnsson will not thoughts one other few years of labor.
