Recently, Xingtu officially announced the wind tunnel test results of its pure electric car, the Star Era ES, which has a drag coefficient of 0.205Cd. This also makes the Epoch ES fully qualified to enter the first echelon of the drag coefficient of global production models, and become one of the benchmarks for the aerodynamic research and development of pure electric cars.
In fact, we have seen many domestic models in the drag coefficient efforts have been very rewarded, the current mass production control of wind resistance first, is a A An incubation h platinum GT (0.197Cd), followed by Jili Galaxy E8 (0.199Cd), and extraordinary F7 (0.206Cd). The 0.205Cd created by the Epoch ES not only surpasses the extraordinary F7, but also once again shows us that there are more domestic brands that have the ability to enter the ding-level "aerodynamic club".
In fact, we have no more demanding requirements for the drag coefficient of the Star Era ES, after all, the blessing provided by aerodynamics for the vehicle is to serve our ordinary users. In front of the Epoch ES, there are either pure electric performance cars that want to pursue chic, or flagship sedans that have been polished for a long time and hope to lead the pure electric revolution of luxury brands with low wind resistance. So in some ways, these models are in favor of others for lower drag.
So when it comes to the Star Era ES, we really hope to have a model that really makes the car more comfortable through aerodynamics, rather than just "showing off".
At this point, we may be able to see some clues from the "tailor-made" aerodynamic design of the Star Era ES by the Xingtu R&D team.
First of all, let's take a look at the "prescribed actions" to optimize aerodynamics on the Star Era ES, and the first one must be the persistence of designers and engineers. According to Xingtu, the R&D team conducted 2,065 CFD simulations, 619,000 core-hours of high-performance computing, and a total of 300 wind tunnel scheme verifications for the overall shape, configuration and dozens of body details of the Stellar ES, and finally obtained a score of 0.205Cd.
When it comes to these efforts, I have to admire the execution of Xingtu. As we all know, the Xingtu brand has not been established for a long time, and it is also a new recruit in the "new forces", but their growth rate is amazingly fast, without the "hundred years of accumulation" like Mercedes-Benz, or the many "joint venture endorsements" of the Q Group, they can also obtain good results with ultra-low drag coefficient in a relatively short research and development cycle, which is inseparable from their own resoluteness and hard work.
In terms of specific styling, the Star Era ES adopts a lot of current popular design languages, such as the overall smooth and rounded body, closed front nose, ventilation grille with active opening and closing function, hidden door handles, electric rear wing that can be automatically lifted, air suspension that can intelligently adjust the body attitude, and a neat tail.
While not a "new fashion", these designs are very effective, such as the sleek bodywork that improves aerodynamics by 23 percent, and other details that can be used to further optimize the drag coefficient. In addition, more importantly, the R&D team of Epoch ES did not pursue lower wind resistance, and too much "new and surprising", which can improve the efficiency of R&D, on the one hand, these already mature optimized designs can also allow the vehicle to take into account the design aesthetics and cabin comfort while low wind resistance.
Next, let's take a look at what other innovations Epoch ES has in controlling wind resistance, first of all, we pay attention to the optimization of the chassis part, Epoch ES adopts the E0X global ultra-comfortable electric platform independently developed by Xingtu, one of its major features is "extra flat", which can not only ensure that the platform in the cockpit is flat enough, but also allow the chassis to have a good flatness, thereby reducing turbulence. In addition, the Epoch ES is also equipped with a full-coverage chassis guard, which can further reduce the wind noise caused by the airflow.
In addition, the R&D team of Xingtu has also made "subtle" low-drag settings for many design details of the Epoch ES, such as exterior mirrors, front windshield, A-pillar, and fastback shape. Because from the styling point of view, we do not feel that they are particularly obvious differences with other models on the "same kind", but the final effect is different, which is actually the benefit of fine tuning, not only in the styling is not detached from the aesthetics of ordinary consumers, but also to achieve aerodynamic optimization, which can be described as killing two birds with one stone. Therefore, the Epoch ES is more in line with the needs of consumers for the appearance and styling of the vehicle, and at the same time, it can also help the vehicle obtain a longer range, lower power consumption level, and better NVH performance by controlling the drag coefficient. As the official launch on the market is approaching, the information of the Star Era ES is also constantly exposed, we have seen the prototype car at the Chengdu Auto Show before, and it impressed me the most at that time is "high intelligence", whether it is the ultra-fast charging ability and more delicate electronic control level of the 800V platform, or the unlimited potential of the LION AI large model platform with the blessing of the 8155 chip and the iFLYTEK Xinghuo cognitive large model, and even the Lion Melody audio, air purification system, etc., are all fully demonstrating the "self-control" of the Star Era ES, how comfortable the driver and passengers in the car can be.
The announcement of the 0.205Cd drag coefficient results also made us suddenly realize that when Xingtu was building a car, it was not only obsessed with how to be more "intelligent + electric", but they also made great efforts in the settings that many cars should have paid attention to. After all, aerodynamics is not a product of the new energy era, but has become the forefront of technological exploration and the embodiment of product value in the era of traditional fuel vehicles.
Therefore, we are looking forward to the "mechanical quality" of the Star Era ES in the future, and the organic integration of the emerging and the traditional may make this flagship pure electric car, which has high hopes for Xingtu, break the existing market pattern and become a "new benchmark" for the emergence of new forces.
