All body parts on the Polestar 1 car, including doors, hoods and trunk lids, are made of carbon fiber reinforced plastic (CFRP), which maximizes rigidity, torsional stiffness, and weight. This rigid body helps to achieve consistent precision characteristics.
Polestar is a high-performance brand of the Volvo Car Group. As a new independent high-performance electric car brand facing the future, Polestar was launched last October. The new dedicated production facility in Chengdu, Sichuan, and a new customer-centric approach to the market will set new industry benchmarks for buyers of this high-performance car through fully packaged, subscription-based services. Since its launch last October, more than 5,000 people have said they are interested in the opportunity to buy Polestar 1.
Polestar Engineered is the high-performance arm of the Volvo Car Group. As a result of Polestar Racing engineers' desire to explore "how the technology behind the success of racing can be used to improve the performance of Volvo cars driving on the road (ie all road conditions in daily life)", it Created by Polestar Racing, today known as "Cyan Racing".
Electric hybrid high-performance vehicle
The company's first car, the Polestar 1, will begin production in mid-2019. As an electric hybrid high-performance car, this car can run 150km in pure electric mode-this is the longest full electric mode mileage of any hybrid vehicle in the market. Combined with the 4-cylinder Volvo Drive-E engine, the Polestar 1 can provide 600hp and 1000Nm of torque, thus firmly positioning this car in the category of high-performance cars.
Polestar will serve as a technology pioneer for the Volvo Car Group to bring new technology and performance attributes to the market. At the same time, it will benefit from the technical and engineering synergies within Volvo Cars and the significant economies of scale that result. These synergies will allow Polestar to accelerate the design, development and manufacture of its high-performance electric vehicles.
50% are new and customized
The first car, called "Polestar 1," will bring a halo to the future Polestar brand. This two-door, 22-seater luxury coupe has an "electric high-performance hybrid" drivetrain, and produces approximately 500 cars per year.
In order to reflect the technological pioneering role of Polestar, Polestar 1 is based on Volvo's Scalable Platform Architecture ("SPA"), but about 50% of it is new and customized. This will be performed by the company's engineers. To create.
Compared to the 5.15m length of the S90, this car is 4.5m in length.
Carbon fiber body
The challenge in making this car is that it will be Volvo's first model with a carbon fiber body. This lightweight material is more common in super cars, and it brings three significant advantages to the car: first, the body weight is greatly reduced by 230kg; second, the torsional stiffness is increased by 45%; and finally, the weight of the upper body panel The reduction in weight reduces the center of gravity of the Polestar 1, which enables better maneuverability, performance and drivability on open roads. Polestar expects that it will take some time for the team to have confidence in this new process, which will be a fairly slow start, but necessary for this complex product.
Polestar 2 and Polestar 3 will follow
All future Polestar vehicles will use an all-electric powertrain. The Polestar 2 will be Volvo Car Group's first battery electric vehicle (BEV), and this mid-size car will compete in a competition around the Tesla Model 3. Polestar 2 is currently in the engineering development stage and will begin production before the end of 2019, with a higher output than Polestar 1. The Polestar 3 is still in the final stages of design. It will be a larger SUV-type BEV, which can create modern performance in terms of electric performance and driving power. Its output and price are between Polestar 1 and Polestar 2. Based on the characteristics of electric motors, most electric cars are fast, but for Polestar, its performance is not just about linear speed, but more comprehensive. This involves acceleration, and of course, turning, braking, Suspension control, chassis feedback, and steering feel are what Polestar calls "progressive performance."
Full of innovation
As part of the Volvo Car Group, Polestar is able to design, develop and manufacture cars using the processes of a well-known car company, but also to test new technologies in low-volume cars outside the mainstream.
Polestar focuses on uncompromising car design and technology, using electricity and innovation to power their cars. Electric vehicles are the main focus of today's automotive industry and are at the center of this development. The company introduces world-class electric vehicles, as well as customer-centric innovative services and supplies:
1.Dragonfly: The application of carbon fiber has greatly influenced the design of Polestar 1: the cross section of the roof is a thin, light and rigid carbon fiber profile, which makes the roof line low and elegant, achieving a beautiful design. In addition, cleverly shaped CFRP patches are bonded to the steel body floor to strengthen the weak interface between the traditional middle layer and the rear structure. At Polestar, this component is called "Dragonfly".
2. Carbon fiber reinforced polymer: Almost all body parts on the Polestar 1, including doors, hoods and trunk lids, are made of carbon fiber reinforced polymer (CFRP) to achieve maximum rigidity, torsional stiffness, and minimum weight. This rigid, rigid body helps to achieve consistent accuracy.
3. Active rear spoiler: The Polestar 1 has a standard active rear spoiler that can transmit high-speed downforce on the rear axle: when the speed exceeds 100km / h, it automatically rises from its integrated horizontal position; and When the speed drops below 70km / h, it returns to its original position.
4. Panoramic glass roof: Polestar 1 has a fixed panoramic glass roof that extends from the top of the windshield to the upper edge of the rear window. A delightful little detail was projected onto the glass roof, and that was "Polestar".
5. Interior design: The interior is characterized by handmade leather decoration and carbon fiber wings that extend to the entire height of the instrument panel. Extremely high processing accuracy guarantees a high level of assembly and finish.
6. Double Keel Front Suspension: The Polestar 1 has a double keel front suspension that connects each wheel with two lateral links. This design enables the front suspension to offset torque steering, providing neutral balance by minimizing unnecessary understeer. In addition to these advantages, most suspension components are made of aluminum, which reduces unsprung weight.
7. The rear suspension is an integrated link design, which is a unique solution for Polestar 1-the use of composite lateral leaf springs instead of traditional coil springs. This design provides neutrally balanced turning characteristics, minimal sway, and low noise, vibration, and irregularity.
