Starting from 1.286 million yuan! No kidding, domestic supercars have started to be delivered

Jing A 00001.

In 1992, the red Ferrari 348 on the streets of Beijing had this license plate. The car owner Li Xiaohua spent US$138,880 in exchange for the legendary story of "China's first supercar" and left a classic photo in Tiananmen Square.

At that time, the socialist market economy had been established and various reform and opening-up policies were basically completed. The 88-year-old man was still touring the south. But if you go to the factory and take a look, you will find that we are still producing models with outdated technologies such as Beijing 212 and Changan Alto.

China's automobile industry is still crawling forward slowly.

Ten years later, a fleet of dozens of Ferraris of different models drove from Tiananmen Square to the Great Hall of the People. Ferrari executives and the Italian Ambassador to China were present in person to jointly organize the "10th Anniversary Celebration of Entering China" with the car owners.

On the other side of the carnival, Geely made China's first domestic sports car, the Beauty Leopard, allowing the Chinese to buy a two-door sports car for the price of a Santana.

At this time, China's automobile industry began to take small steps.

But supercars are different from sports cars. You don’t just spend money on styling, and you can say that you are a supercar after all. Put the Michelin hat on a box of instant noodles, and when you open it, it is still bread and ingredients.

The concept of supercar was born in the 1960s, more than 30 years later than sports cars.

Lamborghini Miura

The world's recognized first supercar is Lamborghini's Miura. It has a mid-mounted rear-wheel drive layout, a 350-horsepower V12 engine, and a top speed of over 270km/h. It has established the typical characteristics and technical standards of the supercar category. As a branch of sports cars, supercars have more extreme performance and represent the highest technical level of the automotive industry.

As the crown jewel of the automobile industry, the purpose of supercars is to challenge the limits of the automobile industry. Twenty years after the birth of China's first sports car, China's first supercar can finally roll off the production line and be delivered to users.

China's automobile industry has begun to make strides forward.

Respond to doubts with action

On the evening of October 9, China's first supercar Haopu SSR rolled off the assembly line and was delivered to the first batch of car owners at the supercar production line of the first intelligent manufacturing center of GAC Aian Intelligent Ecological Factory.

At the same time, the launch prices of three models were also announced:

  • Haopin SSR: 1.286 million yuan
  • Haopin SSR Speed ​​Edition: 1.386 million yuan
  • Haopin SSR track version: 1.686 million yuan

I still remember that in September last year, under the Guangzhou Tower, Haopin SSR appeared in public view for the first time, but most of them were questioned:

ah? Can GAC also make supercars? Selling for more than one million?

It is estimated that it will not be mass-produced, but one will be built to show off.

Tonight, GAC not only mass-produced this car, but also started delivering it directly.

However, the car owners who were holding the keys in their hands at this time still only knew about the Haopin SSR at the level of simple data, such as 0-100 acceleration in 1.9 seconds, 1225 horsepower and 12000N·m peak torque at the wheel… …

Even for a supercar, these are exaggerated figures, especially the torque at the wheels.

▲The left is the motor of Haopin SSR, the right is the conventional motor

In order to achieve tens of thousands of Nm of on-wheel torque, Haopin SSR is equipped with a two-speed four-in-one high-performance motor. The internal stator uses special flat wire Hairpin technology, which is 15% smaller than conventional motors. Its rotor adopts a similar solution to the Tesla Model S Plaid, with a carbon fiber shell to resist the centrifugal force caused by high speeds.

However, the top speed performance of Haopin SSR is not very impressive, just over 260km/h. The good news is that the Haopin SSR, like the Porsche Taycan, has a two-speed transmission, and the addition of the transmission has greatly improved the mid- and rear-end acceleration capabilities of the Haopin SSR.

GAC stated that at Turn 14 before the straightaway of the Zhuhai Circuit, if the Haopin SSR can exit the corner at a speed of 120km/h, then it can increase the speed to 260km/h within 250 meters.

In addition, in the electric drive solution of Haopin SSR, GAC has equipped it with a 900V silicon carbide chip using an all-silver sintering process. The specifications far exceed the industry. The finished chip is 30% smaller than ordinary chips, and the current is increased by 25%. The frequency is increased by 2.5 times, which basically ensures the stability of high power output.

In order to make the Haopin SSR have the performance worthy of the word supercar, in the absence of precedents, the Haopin scientific research team achieved a large number of technological breakthroughs from 0 to 1 from body design, three electrics, to high-performance materials, filling the gap. Filled the gap in the country.

Taking the body as an example, Haopin SSR uses 100% carbon fiber to cover the body. You read that right, all covering parts are carbon fiber.

Since there is no domestic precedent, this is a huge challenge for engineers, whether in terms of styling, body frame, or manufacturing process.

Not only that, the supply of large-area carbon fiber parts is also a big problem. What should we do if we cooperate with mature overseas suppliers? Not only are the costs high, the supply unstable, but also accompanied by extremely long logistics times, but there are no domestic suppliers that meet the requirements? Haopin's approach is to work with suppliers.

Finally, with the cooperation of the carbon fiber body and the aluminum alloy frame, the body torsional stiffness of Haopin SSR is as high as 50475N·m/deg, far exceeding supercars such as Ferrari 488GTB, McLaren 720S, and Porsche 991 (992).

"In the future, it will be much easier for other independent brands to build supercars," said Gu Huinan, general manager of GAC Aion.

Hao Bo, it’s off to a good start.

When former Top Gear host Jeremy Clarkson tested the Tesla Roadster for the first time, he mentioned that Tesla tried a two-speed gearbox when developing the Roadster, but it was the least successful.

They tried using a two-speed (transmission), but they kept having problems.

Since the motor has the ability to instantly burst out huge torque, the reliability and durability issues of the two-speed gearbox have never been solved. Tesla can only resort to the next best thing and use a single-stage reducer to achieve power transmission.

▲Porsche Taycan’s transmission

Among the pure electric models currently on sale, the only model with a two-speed transmission is the Porsche Tacan, but the maximum torque that that transmission can withstand is only 550N·m. The torque carried by the supercar electric drive shaft is twice that of ordinary electric drives. How to improve the strength and toughness of the transmission system in a limited space has troubled the Haopin team for three years.

Later, the Haobin team found inspiration from the huge wind turbine blades on the grassland – the transmission system inside the blades that can bear the weight of tons must not be simple.

And this is just one of thousands of difficulties.

Tires are the only parts of a vehicle that are in contact with the ground and have a vital impact on vehicle performance. Coupled with the Haopin SSR 12000N·m wheel torque, it goes without saying that the requirements for tires are very high.

However, in foreign countries, hot-melt tires are a core confidential technology. Without any experience, Haopin teamed up with the research and development team of the C919 domestic large aircraft to explore the formula of hot-melt tires and picked up pieces of rubber on the track. I took it back and analyzed the components over and over again, tried the hot melt tire formula based on the analysis results, and then took it to the track for actual testing. After hundreds of formula tests, the best hot-melt tire formula was found.

While the tire grip has achieved a leap, the vehicle's braking system must also be improved accordingly. When braking at high speeds on the track, the brake discs will generate high temperatures in an instant. One brake can destroy the cast iron brake discs used in ordinary household cars. . However, the carbon ceramic brake disc technology used in supercars and racing cars is only in the hands of a few overseas companies, and there is no domestic supporting equipment.

At this time, a key figure appeared – Huang Boyun, an academician of the Chinese Academy of Engineering.

As long as I can build a supercar, my carbon ceramic brake discs are free.

Academician Huang said this excitedly when he learned that Haobin wanted to cooperate with him to develop China's first supercar.

However, since there is no mass production precedent, both the process route, development rating system, and processing equipment are blank. After studying for several months, the R&D team found that their solution, friction performance and stability could not meet the stringent requirements of a supercar.

Finally, the R&D team collected almost all domestic resin materials and repeatedly tested thousands of brake discs before finding a resin formula that met the needs. It has also made a breakthrough in applying long-fiber carbon ceramic technology used in aviation to supercar brake discs. It has better toughness and higher strength than overseas short-fiber technology.

Supercars are precious, but this independent supercar industry chain is even more priceless.

As Academician Huang said, building supercars has always been the dream of Chinese car people. In addition to technological breakthroughs, Haopin SSR has also led to a large number of cross-border breakthroughs from parts matching, to experimental equipment, and even testers.

A few months ago, Dong Chehui also talked about the issue of Chinese-made sports cars in "Chinese Sports Cars, Are They Not All Jokes"? One paragraph said:

Originally, I wanted to use the story of Lamborghini's transformation from building tractors to building supercars to encourage China's sports car industry, but to be honest, this kind of encouragement is like online loans. It is difficult for me to be sure that China will produce a supercar like Lamborghini in the future. brand.

But tonight, my worries were put to rest.
