In the world of supercars, performance is always the first priority. But why has the car been invented so far, only a small number of supercars can achieve acceleration performance of 100 kilometers within 3 seconds? What makes the world supercar stop moving forward?
acceleration from 100 kilometers to enter within 3 seconds, and each "0.1" second breakthrough is a JIZHI challenge to power output.
The world's automobile industry has been around for a century, and only the few supercar brands have been born. There is no cultural soil for performance cars and no world's cutting-edge supply chain system. Dreams can only belong to dreams.
In Hyper SSR's view, technical foundation and contemporary factors determine the lower limit of the product , and thinking determines the upper limit of performance. Behind the Hyper SSR's 1.9s-100-kilometer-accelerating world problem is the performance philosophy of "both bear's paw and fish".
There are many conditions that affect vehicle acceleration, and it is easy to lose sight of one thing.
For example, under the same conditions, acceleration is positively correlated with the thrust provided by the powertrain. Dynamic acceleration is performed on the ground with friction, and the acceleration is positively correlated with the friction coefficient. At the same time, air resistance, body stability, and even the driver's driving level will have a direct or indirect impact on the result of acceleration.
Hyper SSR's performance philosophy of "both bear's paw and fish" is not about grabbing eyebrows and beards, but about the overall planning after the outline is fully prepared.
"Bear's paw" is the driving force generated by the powertrain's final fall to the ground, and "fish" is a secondary condition such as air resistance that affects performance. After completing key technical research, successfully got the "bear's paw" and did not forget to wrap the "fish" into . This is the confidence that Hyper SSR can dominate the mass-produced supercar acceleration list.
Eat the Bear Paw
It is not as simple as expected to build a 1.9s supercar. In the past, our understanding of traditional supercars was that if we wanted to gain a stronger initial driving force, we would increase the number of cylinders and press the engine, and at most it would be adjusted by transmission, chassis, etc. When reduces the electric powertrain, what you need is not just to increase the number of motors , but all chips, quality, layout, and electronic control units all require coordination and scheduling, which is far more complicated than imagined.
Hyper SSR engineers decided to focus on their core demands. Since wants to accelerate 1.9sJIZHI, let all other accessories serve the power surge in that moment. Therefore, from an electric drive chip to a complete set of electronic control systems, all of them are produced by the peak torque on the wheel of 12000N·m.
Hyper SSR The world's first two-speed four-in-one high-performance motor is the foothold of peak torque.
When engineers developed this motor, they had only one goal in mind - used smaller volume and quality to create a self-developed electric drive comparable to two or even three motors.
So, when the ultra-high voltage switching in this electric drive solution puts forward "whimsical" requirements for the voltage withstandability and stability of the electric drive system, the engineers unanimously decided that there is no condition to create conditions.
At that time, chips in the automotive industry could only cope with voltages of 450-500V. Engineers sought breakthroughs from high-speed rail technology and developed a 900V silicon carbide chip with specifications far exceeding the industry, and adopted the all-silver sintering process . The finished chip of Hyper SSR is reduced by 30% compared to the ordinary chip, with a current increase of 25%, a stray inductance reduced by 40%, an operating frequency increased by 2.5 times, and a power consumption reduced by 80%. ensures the stability of high-power output, and is also compatible with the package at the application level, and can be used freely at different powers and voltages.
But this is only the first step in a thousand miles of peak torque on the 12000N·m wheel.
Under the same conditions, the larger the mass, the smaller the acceleration. With the support of high-quality materials and component design, how to complete the layout of the electric drive system and reduce the quality of the vehicle in a limited space is once again blocking the way forward.After tens of thousands of repeated designs and continuous optimizations, engineers have successfully developed the flat line Hairpin technology. This unique wiring method reduces the system space volume by 15% and the weight by 20% . The problem of spatial layout of
has been solved. How to increase the voltage several times between electric and light to ensure that the battery energy can be quickly transmitted to the driving motor?
Engineer " and " challenged the operation logic of the electronic control system.
Finally, Hyper SSR engineer full stack self-developed Edrive 3.0 intelligent control system , embedded with superior performance control algorithm , including high-precision torque control algorithm, high-precision torque/current calculation, high-precision junction temperature/water temperature calculation, wide voltage overmodulation technology, soft decoding and positionless control technology. The modular design of the instructions of the program greatly improves the execution efficiency, significantly reducing logical redundancy and time redundancy.
� is output from the battery, to the electronic control, motor, and output to the half-axis after the difference reduction. The ZUIGAO efficiency of the electric drive assembly reaches 94.5% . The two-speed four-in-one high-performance motor is combined with other motors. When fully propelling, it can release a 12,000N·m peak torque of , allowing Hyper SSR to have the rocket's pushback feeling that the rocket takes off immediately.
The performance breakthrough of the world DINGJI supercar is the first time for every Aian engineer to cross the river by feeling the stones. But it is precisely this kind of concentrated breakthrough in technology clusters with focus and determination that makes it possible to break the acceleration limit of mass-produced supercars.

When the torque of the powertrain that stands out as the champion becomes a reality, the performance research and development path of Hyper SSR has officially entered the "broad of flowers" stage. Whether it is the tires that can directly affect dynamic acceleration, the aerodynamic design, or the braking technology that indirectly affects handling performance in extreme speed states, the car body rigid technology has become the "fish in the net pocket" of Hyper SSR one by one.
The greater the friction force of the tire, the greater the contribution to performance during the dynamic acceleration stage. Part of the reason why many supercar brands are difficult to achieve a breakthrough of 100 kilometers within 3s is due to the shackles of tire technology in the automobile industry.
The tire running on the ground cannot be found, so I look for those flying in the sky.
Hyper SSR engineers found the R&D team of the domestic large aircraft C919 tires. They adopted the core technologies of aviation tires such as low heat generation formula and low expansion rate design. Finally, they developed high-performance tires with a friction coefficient far exceeding the same level, allowing the vehicle's dynamic acceleration effect to meet the calibration requirements .
When the acceleration of 100 kilometers enters the 3-second range, wind resistance becomes the second "stumbling block" after the friction coefficient.
For this reason, Hyper SSR's body design engineer seeks breakthrough inspiration from the aerodynamic model of the fastest-flying bird in the world, the fastest flying bird, and has developed a " Wind-eating " design thinking that combines aesthetics and aerodynamics . The air intake grille on the front face of
is connected to the air intake channel, which introduces the airflow in front of the vehicle into the cabin and flows out from the flow guide under the front windshield. Combined with the peregrine airflow channel used on the side of the vehicle, can effectively sort out the air turbulence in front and side .
At the same time, the air intake channel located in the fog lamp area of the traditional vehicle is combined with the wheel cavity airflow channel at the bottom of the door, and significantly improves the turbulence in the wheel bag and achieves the effect of reducing air resistance .
In addition, the actively lifted tail wing can effectively increase downforce when raised, improve driving stability, and reduce wind resistance when closed.
In order to make the performance easy to control after the transformation, Hyper SSR also works with DINGJI suppliers to provide a solid structural foundation for 1.9sDINGJI performance, further solving problems such as braking and safety. aerospace-grade long-fiber carbon ceramic disk solves the problems of foreign short fiber carbon ceramic disks prone to cracking after impact and poor cold braking performance. The braking performance is as stable as a rock.100% carbon fiber covers , and produces carbon fiber with a weight of less than 1/4 of the steel and a strength of 6 to 8 times stronger than steel, adding a layer of guarantee for body safety.
It is worth noting that Hyper SSR, from a two-speed four-in-one high-performance motor to a small piece of long fiber carbon ceramic disc, is 100% developed in China and made in China. Supercars are representative of the strength of DINGJI in the automotive industry. The cross-historical development from 0 to 1 is a family and a generation of achievements.
Aion's performance philosophy of "bear paw and fish" has made the beginning of Hyper SSR, and it is the strong accumulation and technical foundation of the Chinese automobile industry that supports the ideal of "Chinese supercars" from design to reality. believes that under the leadership of the 1.9s Chinese supercar, more products leading the times and the world will emerge and become the backbone of the development of the "Chinese Creation" era.
