All along, it seems that the new forces are firing at traditional car companies. For example, mocking traditional car companies, a bunch of stinky technology, do not understand the needs of users, or do not understand why someone wants to buy a fuel car, so like to smell gasoline, each time can cause a very wide range of discussion.
Recently, a traditional car company launched a counterattack, in the mocha DHT-PHEV online conference, Weipai CEO Li Ruifeng bluntly said that the new forces generally lack core technical reserves, and it is impossible to create DHT hybrid models. It is even mentioned that the new forces have chosen the extender as a backward and low-threshold technical route.
As the head of an important brand under a traditional car company, Li Ruifeng seems to be a bit "rushed" to say such words, unlike the style of traditional car companies. However, let's calm down and taste whether what he said makes sense.
(1) 9 years of grinding a sword, DHT hybrid technology is longer than the history of new forces?
In 2013, the first generation of hybrid technology of the Great Wall was officially established, which is the predecessor of lemon DHT hybrid technology, and even at that time, Weipai was not yet established. Great Wall did not choose series hybrid or parallel hybrid like many car companies, but chose the mixed hybrid with the highest technical difficulty.
Series hybridization is actually the extended range hybrid engaged in by many new forces now, the engine is connected in series with the generator and the drive motor, the engine is only responsible for power generation, and the motor is only responsible for driving. The advantage is that the driving texture is no different from that of pure electric vehicles, and because the engine can "travel", there is no mileage anxiety. The disadvantages are also obvious, the efficiency of the motor decreases after high speed, but it can still only be the scalp, and the high-speed driving texture and fuel consumption are not very friendly.
Parallel hybrid is the hybrid mode used by many German cars, that is, the engine drive and the motor drive are connected in parallel, and the two are connected in parallel through the traditional mechanical transmission, and the transmission control system determines when to use electricity and when to use oil. The advantage is that the structure is simple, the control is simple, the performance is strong and energy-saving when the power is abundant, and the disadvantage is that once the power is fed, it becomes a complete engine drive, and it also carries a large battery, which is worse than the fuel vehicle.
The technical difficulty of both hybrid forms is relatively low, and the disadvantage is that the upper limit is not high, after all, their innate disadvantages cannot be eradicated. Therefore, the Great Wall chose the mixed mode at the beginning, launched in 2013, and did not launch the first generation of DHT hybrid system until 2018, but it was limited by the technology at that time and failed to become popular.
It wasn't until 2021 that Great Wall launched the second-generation DHT system, which we now see as lemon DHT, which solved many problems in the original system. The Great Wall has used all the new technologies in fuel system and electric technology for so many years to achieve quite excellent results.
Taking the newly listed Mocha DHT-PHEV as an example, it uses the innovative high-energy density battery PACK of Honeycomb Energy, coupled with the latest lightweight box molding process and CTP group technology, the battery energy density has reached an astonishing 165WH/KG, which is also the biggest reason why it can be loaded with a 39.67kWh large battery, and also allows the new car to achieve a long endurance of 204km.
In terms of motors, the new car also uses the latest flat wire motor, which is more energy dense than the traditional circular motor than the latest flat wire winding technology, and achieves a stronger power output. Coupled with the efficient hybrid special engine, the specially developed multi-mode hybrid transmission has increased its efficiency to a new dimension.
The Great Wall's set of technology, from the official launch, to the current shine, took a full 9 years. This cycle is longer than the history of most new forces building cars, and the technical barriers involved in the engine, battery, motor, control system, etc. are also quite high, and it is really impossible for the new forces to play.
Therefore, although Li Ruifeng is a bit "rushed", it is indeed a fact, with the car-making resumes of the new forces, he does not have the ability to build such a high-tech difficult model as the MOCHA DHT-PHEV.
(2) Extremely "smart" travel, the new forces take the head?
The Great Wall has done a summary, lemon DHT has "fast", "smooth", "quiet", "provincial" four major advantages, in fact, compare the Mocha DHT-PHEV and the new force representative ideal ONE to know, the Great Wall This is really not blind.
First of all, the vast majority of the working conditions of mocha DHT-PHEV in the urban area are actually driven by front and rear dual motors, which is the same as the ideal ONE, and the permanent magnet synchronous motor is used. But on closer examination, the difference is big, the total power of the front and rear motors of the Mocha is 265kW, the maximum torque is 532Nm, and the total power of the ideal ONE's front and rear dual motors is 245kW, and the maximum torque is 455Nm, which can be clearly seen that the performance of the Mocha motor is more powerful.
Don't forget that the mocha can be synchronized with the engine, while the ideal ONE can only be driven by the motor from beginning to end, even when the high-speed motor is down. The system output of the MOCHA DHT-PHEV can reach 355kW, and the combined torque can reach 762Nm. Its 0-100km/h acceleration time is 4.8 seconds, which is the top performance car level, the ideal ONE's 0-100km/h acceleration time is 6.5 seconds, the general steel gun level, this difference is still relatively large.
Speaking of "shun" and "static", the Mocha DHT-PHEV uses a 1.5T four-cylinder engine as the engine and power source, while the ideal ONE uses a 1.2T three-cylinder engine. The Great Wall itself has nearly 20 years of experience in engine design, production and manufacturing, and the ideal ONE is a third-party engine purchased, who is smoother, who is more quiet, naturally needless to say.
In terms of power drive, the Great Wall uses a self-developed 2-speed DHT hybrid professional gearbox, which is specifically responsible for the deployment of vehicle performance, while the ideal ONE is a third-party fixed gearbox purchased, whose work is smoother naturally needless to say.
Finally, when it comes to provinces, both are actually oilable and electric. However, the pure electric mileage of the MOCHA DHT-PHEV is more than 200km, and the ideal ONE is 188km, even if the two may also have a difference in the "fidelity" of the battery life, it is also the former pure electricity that runs farther.
In the feed-in state, the fuel consumption of the two-wheel drive version of mocha DHT-PHEV is 5.55L/100km, and the fuel consumption of the four-wheel drive version is 6.3L/100km. Ideal ONE has not released the feeder fuel consumption data, but it is roughly around 10L/100km, which is not bad compared with fuel vehicles, but it is really compared with the high-level hybrid vehicles such as Mocha DHT-PHEV, and the disadvantage is still relatively large.
Therefore, it is not Wei brand arrogance, the performance of the Mocha DHT-PHEV is stronger, and avoids the problem of low motor high-speed efficiency, smoothness and NVH Mocha DHT-PHEV is better, the key can be more fuel-efficient, indeed the new forces can not fight. Not to mention that the gap between the two in terms of car manufacturing experience and quality control may be even greater.
But this is not to say that the Mocha DHT-PHEV must sit back and relax, even Wei brand CMO Qiao Xinyu admitted that the new force is 3 points to build a car 7 points, Wei brand is 7 points to build a car 3 points to say.
Just like mocha DHT-PHEV so good, we have to let more consumers know. In addition to focusing on technology, traditional car companies should also make more efforts in publicity and look up to the new forces.
(4) Kung Fu shooting
Weipai CEO Li Ruifeng's "firing cannon" this time is a bit like "taking the other way and returning the other body".
To some extent, he said that the new forces could not create lemon DHT, but he was also telling the truth, after all, the Great Wall's technological accumulation for so many years is not something that the new forces will be able to catch up with for a while and a half. Judging from the specific performance of the vehicle, the Mocha DHT-PHEV is indeed a perfect one in four dimensions.
