With the continuous increase of R & D investment, domestic forces have achieved fruitful results in engine research and development, and have successively brought surprise breakthroughs. Previously, changan automobile blue whale series once it came out, it attracted many attention and became the brand's killer to seize sales. Chery Automobile has successfully won a number of fans by relying on Kunpeng Power, and many of its new cars have thus ranked among the star models, and the market prospect is very broad. In addition, there are a number of car companies have independently developed engine technology, the entire industry presents a hundred flowers blooming situation, as if there is a reproduction of the Japanese brand that "buy engine and send car" trend. However, in the 3.0T level, the participating brands are more limited. This article will screen out the research and development achievements of the three major domestic car companies in the engine to see who is better.
Great Wall Motors
Model: E30Z
Engine: 3.0T V6 turbocharged
If you talk about fame, the Great Wall Engine will not let go. As a 3.0T specification, the engine has Miller cycle technology, which can achieve 38.5% ultra-high thermal efficiency, which not only has a purer power output, but also effectively improves fuel economy. It also uses a GDI+PFI dual-jet system and provides a smooth power delivery with dual electronic throttle valves and dual VGT superchargers. The engine and the 48V light hybrid system are mutually exclusive, which can greatly improve output efficiency and keep up with the current trend of new energy tide. In fact, the Great Wall not only made sufficient efforts in engine research and development, but also spent a lot of money on the transmission system. The engine is matched with the Great Wall's self-developed 9AT gearbox, which is silky and smooth when switching gears, and the driving experience is more enjoyable. The maximum power of this set can reach 260 kilowatts, and the data performance is superior to that of many opponents.
When it comes to the Great Wall 3.0T engine, it is necessary to mention the recent explosion of the tank 500. Although it has not yet been officially listed, the car already has the strength to become a "phenomenon-level" star, and is expected to reproduce the glory of the tank 300. After the start of the pre-sale, the new car won the favor of many parties, receiving more than 20,000 orders in just two hours, and successfully broke through the 40,000 mark in the first week, showing strong market competitiveness. The reason why it can take the lead, the tank 500 not only relies on excellent shape and rich configuration, but also the Great Wall 3.0T+9AT combination is the key. It is estimated that after seeing the popularity of the tank 500, Great Wall Motors will be full of confidence and apply it in the next many new cars. It is worth mentioning that among all the domestic 3.0T engines, the Great Wall is the one with the most public information. This also reflects its confidence and is not afraid of doubts and speculations from all sides.
Wuling
Model: 6G30TQY
"The People's Wuling" can be said to be everywhere, and its figure can be seen in many subdivisions. But I didn't expect that Wuling, which has been taking the people-friendly route, has also made great achievements in high-performance engines, and its strength is really unfathomable. In fact, the Wuling 3.0T engine is very interesting, as early as January 2018, it was successfully ignited, which can achieve a maximum power of 206 kilowatts, and the peak torque is 420 Nm. Perhaps in terms of data, the Wuling 3.0T engine is still a little insufficient compared to many competitors, but its cost performance is really excellent, continuing the brand's consistent strategy.
Although there is not yet a single model of Wuling equipped with this engine, it has been successfully purchased by other car companies and applied to the 2020 Beijing BJ80. The engine on the car is built by Lingte Power, and behind the company is Liuzhou Wuling Liuji Power Co., Ltd., which is actually produced by Wuling. It is expected that in the near future, Wuling will give the 3.0T engine to the new car, seize the market space with strong performance, and expand its brand influence.
red flag
Model: CA6GV30TD
Engine: 3.0T V6 supercharged
Compared with the above two engines, the big brother of domestic car manufacturing strength, Hongqi, has been criticized. At the time of its launch, although Hongqi officials had been saying that the engine was developed independently, many people believed that it essentially borrowed from Audi's previous generation EA837 3.0T engine. The two have similarities in many ways, and it is inevitable that this criticism will be avoided. As for why the truth is in the end, we will no longer delve deeply, after all, the true and false are only known to the parties.
Returning to the engine itself, the Hongqi 3.0T engine does not use the mainstream turbocharging method, but uses mechanical supercharging to attract people's attention. Its advantage is that the power response is more positive and rapid, and the output is more abundant. However, the defect is that the power loss is large when doing high-speed work, and it is lacking in fuel economy. The car is based on the Otto circulation combustion system, using a 200 bar injection pressure in the cylinder direct injection system, technically compared to the Great Wall engine is still a bit different. At present, the engine is applied to the Hongqi HS7 and H9, and the reputation is not bad, and the sales volume has also reached expectations. In fact, as the big brother of domestic car manufacturing forces, Hongqi has always been a bellwether in engine research and development. No matter how many doubts there are about the 3.0T engine, it does not affect the status of the two words of red flag in the hearts of consumers.
