In the minds of car fans, Mazda belongs to the technology house that is obsessed with research and development, and in the domestic brand, there is also such a typical representative, also very intoxicated in technology research and development, and even by consumers called "domestic Mazda", in many domestic products do not have core technology research and development capabilities, it has developed an engine with independent intellectual property rights, saying this, I think everyone must have understood who this brand is. That's right, Chery.
Chery's overall sales are not very high, last year won 550,000 new car sales performance, but compared with Geely, Changan, Haval is still a big difference, and even by BYD far behind. However, everyone agrees that the sales volume is not in the domestic head camp, but if someone questions Chery's three major technologies, it may cause a scolding. So, this Chery, known as "domestic Mazda", has the three major pieces of technology been mythologized?
motor
Chery's engine strength is beyond doubt, or in 2001 Chery has begun to AVL cooperation to design 18 engines with 0.8-4.2L displacement, and in 2005, Chery's first completely positive independently developed ACTECO engine ignited off the production line, its emergence rewrote the blank history of Chinese brands without independent core technology, narrowing the gap with the world's advanced engine level.
This 0.8L inline three-cylinder engine was first installed on Chery QQ, the maximum horsepower is 52Ps, the peak torque is 70N·m, and now the parameters are extremely low, but at that time many consumers were not so concerned, and at that time, other car companies were using Mitsubishi engines to survive, only Chery began to achieve self-reliance. More importantly, the self-developed engine has greatly reduced the cost, and Chery QQ can enter the market at a very low price and open a sales myth in the market.
Today, Chery's ACTECO series engine research and development has been updated to the third generation, of which 1.6TGDI, 2.0TGDI has covered a number of Chery Group models, Tiggo 8 series, Jietu X95 Xingtu, etc., and has a deep influence in the market, and the technical strength should not be underestimated. Among them, the maximum horsepower of 1.6TGDI has exceeded 197Ps, and the peak torque is 290 Nm, which is comparable to many joint venture 2.0T displacement engines, such as the Volkswagen EA888 2.0T low-power version with a maximum horsepower of 186Ps. In fact, this 1.6TGDI engine has also won the title of "China Heart" 2019 Top Ten Engines.
The 2.0TGDI is even more powerful, with 350bar ultra-high pressure direct injection system, small inertia turbine, dual mass flywheel, Miller cycle and other technologies, thermal efficiency of up to 38%, and smoothness and comfort are also guaranteed. Among them, the low-power version has a maximum power of 254Ps and 390 Nm, while the high-power version has a maximum horsepower of 261Ps and a peak torque of 400 Nm, and its power reserve is actually equivalent to the level of 3.5L V6 engines. Also take the volkswagen EA888 high power as an example, the latter has a maximum horsepower of 220Ps and a peak torque of 350 Nm.
transmission
Chery has a deep knowledge in the field of engines, so what about in the field of transmissions? In fact, Chery's time to develop a transmission is not short, it set up Chery Precision Machine in 2003 to develop A CVT transmission, in 2009 the first CVT transmission off the production line, and later began to develop 4AT transmission, and have been successfully applied to mass production models.
Although there is no problem with self-sufficiency, export sales are not ideal. In 2016, Chery sold its transmission technology to Wanliyang and obtained a partial stake. So now in the transmission of this piece is actually Chery's short board, but the Great Wall in the transmission is more prominent, its 7-speed dual-clutch transmission has been selected into the international transmission selection of the world's top ten ranks, its maximum bearing torque up to 450N · m, transmission efficiency as high as 94.41%. In addition, Great Wall has also developed its first longitudinal 9AT automatic transmission, with a maximum carrying torque of up to 600N·m.
chassis
The chassis is a big project, and it may be more complex than the engine transmission, including four parts: the transmission system, the driving system, the braking system and the steering system. Chassis may be considered the weakest of the three major pieces of technology of domestic brands, but Chery actually realized the importance of the chassis very early, unlike other domestic car companies are still reversing the joint venture car, Chery very early began the positive development of the platform, after more than four years of efforts, Chery's first T1X platform was officially launched in 2016, breaking the technical bottleneck, when the first model Tiggo 7 was widely praised, including T1X, now Chery has three major platforms M1X, M3X。 However, time has passed to today, the Great Wall also has its own lemon structure, Geely has a CMA, and the latter seems to be much higher than Chery in terms of fame, and Chery, which started early, does not have much advantage. However, in addition to the hardware standards, the key factor of the chassis is still to look at the adjustment, which also means that more deep experience is required, relatively speaking, Chery's vehicles perform well in handling, but the comfort may be slightly worse.
Overall, Chery's three major pieces of technology do rank among the best in domestic production, but there may still be some unsatisfactory transmissions and chassis. However, Chery has always been full of research spirit, and it is also expected that it will continue to make progress in the future.
