The bones are "light" strange
Bonded Aluminium Platform？
Polar star 5 is the only official rendering
Let's not talk about this new car. Because I just wanted to go back in time to February 15 and say something else.
Does this still make people orgasm?
The next day of Valentine's Day, I was a little tired. Polarstar, far away on the other side of Eurasia, has released some details of its future model, the Polestar 5, which is still under development. I have to say that after seeing these pictures, I orgasmed again. This car instantly made me feel that it could replace the ill-timed Polar Star 1 as the brand's true halo car.
Why is a frame so exciting for me? Please let me enlarge the picture first.
Everyone comes looking for stubble
If you find the paint bucket in the back seat and the Inco Medical (300677, there may be a lot of people trapped) brand gloves on the top of the tower, then congratulations, you are completely off topic.
This picture was taken at the PoleStar R&D Centre in Coventry, the "Racing Valley" of the United Kingdom. The R&D site is a little chaotic, it is normal.
What did you find?
Now, turn your attention back to the yellow circle. Can you find these British guys who can't even glue? No wonder the British car industry is in decline... Sorry, the British car industry is a bit decayed, but it is still the center of the racing industry and the sports car manufacturing universe.
So the question is, why do you want to glue here? And there are a lot of rivet-like things. Because, this car uses an all-aluminum bonding platform. As the name suggests, the production process of this frame is to combine various shapes of aluminum alloys with special epoxy resins and rivets to obtain a stronger and lighter body.
Where's the power?
First of all, aluminum alloy is used on the body, which is more advanced than steel. Aluminum alloys are less dense, so more materials can be used to optimize the structure and increase body strength.
The use of glue to connect body parts has a decisive advantage over simple riveting or welding: the combination in surface units. Rivets can only connect two parts in points, while welding can achieve at most a line connection.
Both methods create greater pressure and stress at the joint than connecting the body with glue, making it impossible to reduce the thickness of the material in the relevant parts. By bonding the frame with glue or epoxy resin, thinner materials can be used without considering whether the material will deform during welding and whether the strength characteristics will be changed by heat.
Well, it's very British. Because this type of car in the world basically comes from the United Kingdom. Examples include Lotus's Elise and Exige, as well as Evora and Aston Martin's DB11, DBS Superleggera, and the more niche Morgan.
Lotus Evora, almost entirely made of aluminium profiles, has a low cost but low space utilization.
Aston Martin DB11, which adds stamped parts with complex shapes, costs more.
84 years later, Morgan also began to use aluminum alloy bonding platforms.
However, the aluminum alloy bonding platform, which seems to be strong and lightweight, and is obviously cheaper than carbon fiber, obviously has its drawbacks.
This disadvantage is production efficiency. Parts need to be fitted with glue and then wait for curing, which requires a lot of labor, not a frame that is very suitable for mass production. But Polestar claims that 280 engineers from the UK's R&D department with professional backgrounds such as F1 and small-volume sports cars have found a way to mass-produce such frames.
Hanging also has highlights?
In fact, Polestar also emphasized that the Polestar 5's body-in-white will be lighter than a one-class smaller vehicle, while providing a stronger torsional stiffness than a 2-seater sports car or supercar. Looking back at the picture, you will find that the upper swing arm of the front double wishbone suspension in the blue circle is significantly lower than that of normal models, usually referred to as low double wishbones.
High double wishbones
Low double wishbones
Double wishbones are common in first-class models, but low-level double wishbones are usually a supercar-only configuration. The lower mounting position of the swing arm brings many advantages, the most obvious of which is that the horn part can be shortened, which is conducive to lightweighting, and it is more important to reduce the unsprung load of the control.
Polestar 5 develops prototype
Secondly, the low double wishbones have less restrictions on the width of the wheel hub, and can also obtain a lower front line. However, because of the relationship between the installation position and the principle of leverage, the strength requirements for the upper swing arm and its installation position and bushing are increased, which is obviously only suitable for higher performance frames.
Do you like the $1 million "Mondeo"?
So, the Poelstar 5 will be one of the best frame materials in a four-door sedan after aston Martin's Logonda Taraf.

In the era of electrification, there is no emotional value but only performance indicators power unit is obviously not enough to constitute enough differentiated competition, but the frame and chassis materials and forms can still distinguish between a car's advanced or not, and on a four-door sedan can experience a design and manufacturing process comparable to a sports car, which is why Polestar 5 let me climax.
alas? Such a good frame, is it only a car?

Render the picture, don't get too excited
Isn't that coming? It turned out that this was the real Halo Car.
Hard-top convertible 2+2, and drones
The back row is comparable to the 911
Family-style lines
The Swedish gold seat belt is alive, probably because it has a high performance package
Familiar car UI
It's a two-door 2+2 electric hardtop convertible production vehicle with a photographic drone that can take off and land automatically in the negative pressure area at the rear. The drone came from Aerofugia, also invested by Geely. The design of this car is a very typical Polar Star, and as a concept car, the specific configuration and data are not the focus. So next, I'll introduce some of the ideas that are more representative of its innovation.
Oh yes, concept cars, it's normal to be a little bit virtual. Concepts that move people's hearts are considered success.
Carry environmental protection to the end
Seat material recycling
In terms of interior, the seat belts, as well as the soft materials of the seats and some other interior materials, are composed of the same material. Polestar calls it the "Mono-materials" concept. Since many materials are bonded together, it is often difficult to recycle these interior materials, resulting in the generation of useless waste. By unifying materials, Polar star allows more interior materials to be recycled, reducing the burden on the environment.
label
Garbage sorting
For the aluminum alloy material of the body, Polestar has labeled each part, which has the advantage of sorting and recycling the aluminum alloy when disassembling the body, so as to ensure that the re-melted material retains the same mechanical properties.

Dialogue Design Director Maximillian Missoni
Max himself looks like this
In order to learn more, this time Garage 42 successfully connected to Max in California.
On March 3, the interview at 7 a.m. trapped me.
At the end of the article, I would like to present the main points of this interview:
Is the convertible easy to do?
Wang Honghao's big guy was also there
Max said that at this stage, the focus of the car as a halo car is to show the possibility of this bonding platform, but it is difficult to achieve such a line, and the mechanical details will be ensured by professional engineers.
Take advantage of small batches
Based on his answer and the platform's small-batch properties, it's not hard to guess that the car really seems likely to be mass-produced. He also stressed that the bottom battery of this all-aluminum bonding platform is not tiled, which will provide better rear foot space. This is the same idea as the Porsche Taycan and Lucid Air.
What is the meaning?
This composition, love
To sum up Max's answer: Literally, it's oxygen. The meaning is that you can breathe the driving pleasure of nature's convertible model and the clean air brought by pure electric and environmental protection concepts.
Are there other colors to choose from?
This angle has a bit of a Taste of Lancia Stratos, what do you think?
Max thinks this is a very good question. For color selection, it uses the word "astringent" to describe pole stars. If a brand offers all the colors at the beginning, then the impression that the brand presents in the design is actually unclear and powerless. Therefore, Polar Star needs a clearer visual tone in order to have a clearer visual expression. In order to cater to more tastes, there will be more colors to choose from in the next models, of course, provided that the colors are carefully selected in line with the brand image.
What's going on with drones?
Don't know how waterproof it is?
Max said it was a joint decision by Polestar CEO Thomas and Geely Group President Li Shufu. The joy of driving should also include the joy of sharing.
Three modes and different distances are available
But just shooting is not much fun, about this, PoleStar has actually made a preliminary idea, that is, different shooting modes are optional.
Of course, due to various regulations and engineering feasibility issues, such a device will have various conditions even if it is mass-produced, but this undoubtedly opens up a more specific UAV game. The concept of a drone proposed by Mission E, the predecessor of the Porsche Taycan concept car, is not known whether it will be implemented by Polestar. It's best if it can come out, and it doesn't matter if it can't come out. Anyway, the real incense is still polestar 5. Anyway, we'll see.
