As a leader in the sales of the luxury car market in China, Audi understands the mentality of Chinese consumers. Lengthening, displacement, and naming are all ahead of Mercedes-Benz and BMW. However, compared with competing products, Audi has always been actively changing, but it has had little success. This is the transmission. As early as 2009, BMW took the lead in picking up an 8-speed automatic transmission from ZF. Today, except for the high-performance model, all rear-wheel drive models are equipped with this 8AT transmission. Mercedes-Benz's action was later. In 2014, it launched a self-developed vertical 9-speed automatic transmission, and gradually replaced the old 7AT with the remodeling/regeneration of its models. The transmission of Audi's models is a bit complicated, and the entry power of many models is compatible with the Multitronic CVT. Most models match the 7-speed S-tronic dual clutch, while the flagship models Audi A8 and Q7 are all equipped with 8AT. The new Audi A4L was equipped with a new dual clutch transmission model DL382. Mercedes-Benz 9AT BMW 8AT Look dizzy? You did not see the halo I also said dizzy. To put it plainly, BMW and Mercedes-Benz are all using the same transmission (except for the high-performance version), and Audi is using a variety of transmissions. As for why, we can see that every Audi of the transmission understands it. Audi's Entry Power Match - Multitronic Continuously Variable Transmission Did you hear that the name Multitronic was instantly intimidated? In fact, this is the CVT stepless transmission that Audi has used on a large scale, the previous generation A4L1.8T (30TFSI), 2.0T low-power models (35TFSI); the cash A5 1.8T (35TFSI) , 2.0T (45TFSI) predecessor models; cash A6L 2.5L (30FSI); cash A7 2.5L (30FSI); even Audi's flagship model A8 V6 self-priming engine and low-power 2.0TFSI models are equipped with this Multitronic no Transmission. Multitronic advantages Audi's Multitronic, like traditional CVTs, uses V-belts to continuously adjust the reduction ratio, but the difference is that Audi not only uses high-strength, multi-disc belts to meet larger displacements such as 2.8L and 2.0T engines. Torque demand is to optimize the hydraulic system to a certain extent to reduce the phenomenon of strip slippage during rapid acceleration. Disadvantages of Multitronic Continuously Variable Transmission Although Audi has made many improvements to Multitronic, it has not fundamentally solved the phenomenon of “slippage†and “hysteresis†of traditional CVTs. Coupled with the increasing popularity of current turbocharged engines, maintaining a relatively low rotational speed makes it difficult for turbines to effectively intervene to increase torque, making the driving experience greatly compromised. Audi finally decides to give up Multitronic Although the Audi Multitronic has natural advantages such as smoothness and low fuel consumption, its disadvantages are also obvious. The Audi Multitronic is not compatible with its flagship Quattro four-wheel drive system, and the Audi Multitronic cannot withstand more than 2.0T of torque, so it is destined to be carried on the predecessor model. Ever since, Audi officially announced that it would officially abandon the Multitronic (CVT) transmission, which is relatively simple in structure and relatively inexpensive to manufacture. Audi's mainstream transmission - 7-speed S-tronic dual clutch Compared to the Audi Multitronic continuously variable transmission, we are undoubtedly more familiar with Audi's other transmission - 7-speed S-tronic dual clutch. Because this transmission has almost all of its models except the flagship models A8 and Q7. I heard that S-tronic is a high-end version of the popular DSG? Yes, but not all! Volkswagen Golf Audi A3 First correct common sense mistakes. Some people say that S-tronic is the name of the Volkswagen DSG, in fact, this sentence is only half right, because for the Audi A1, A3, Q3 7-speed horizontal double clutch and Audi TT on the 6-speed horizontal double clutch really It is a dry DQ200 and a wet DQ250 from the public. However, other models equipped with longitudinal engines such as the A4L and A6L are not the DSG dual clutch transmissions of the public. As for Audi's proprietary vertical dual-clutch transmission, we must start from its history. Why does Audi use the 7-speed S-tronic dual clutch on a large scale? Audi Roadjet Concept Car As early as 2003, Volkswagen was the first to apply the dual clutch technology to the fourth-generation Golf R32 with Audi's family. The Audi DTT with the golf platform was also equipped with the same DQ250 transmission. The Roadjet concept car that was exhibited at the Detroit Auto Show in late 2006 was equipped with a vertical seven-speed dual-clutch transmission, which was later known as the S-tronic dual-clutch transmission. Due to the relationship between Audi and the public, Volkswagen vigorously promotes the dual-clutch transmission. Audi seems to have no reason not to use it. However, for this dual clutch, the impression given to us does not seem to be very good. The secret behind the replacement of the Audi Q5 transmission Audi Q5 with dual clutch transmission This matter has to start with the domestic Q5 listed in March 2010, the new car is equipped with a 7-speed S-tronic dual clutch transmission as the selling point, but just eight months after the listing, Audi will change its money through the year. At the time, all the gearboxes of the main models were replaced by 8-speed manuals, and the 7-speed S-tronic dual-clutch gearbox was retained only in the less-selling dynamic model. Why doesn't Audi say that the standard is 8AT? As for the reason why the replacement of the transmission is an editor of the twin-clutch reliability problem of the rumors, I have no way to verify. However, it is interesting to see that the old and new models have the same quality and the engine parameters remain unchanged. The Q5 with a 7-speed S-tronic dual-clutch transmission has a 8.6s 100-km speedup of 0.7 seconds slower than the same model with the 8AT gearbox. And it has always been an efficient, fuel-efficient, self-contained dual clutch transmission. The fuel consumption performance of the Ministry of Industry and Information Technology is not as good as that of a model equipped with an 8AT transmission. 8AT transmission equipped with Audi A8 Why is Audi not all equipped with a conventional AT transmission that is more reliable and durable than the dual clutch transmission and has mature technology and low shifting speed and efficiency? For flagship models like the Audi A8 and Q7, the standard is 8AT. Transmission, not equipped with Audi's S-tronic dual-clutch promotion? In addition to the cost of transmission, the editors really can not think of other reasons. Is the cost of the Audi S-tronic really low? The S tronic 7-speed wet dual clutch transmission equipped with Audi's new A4L model DL382 has been localized at the Tianjin Volkswagen Automatic Transmission Factory. As for the reason why it is a Volkswagen plant, because in addition to the DL382 this dual clutch transmission, the public nowadays the mainstream DQ380 and DQ500 transmission is also produced in this factory. And if no accident, the future replacement of domestic Q5, the replacement of domestic A6L will also be equipped with this new 7-speed S-tronic dual clutch transmission. Domestic + large-scale pickup, is it not cheaper? The full text concludes: Whether it is Multitronic or S-tronic, although in some respects it shows good performance, but compared to BMW's 8AT and Mercedes-Benz's 9AT, the lack of balance is currently the biggest problem facing the Audi transmission. And if the 8AT transmission carried by the full-scale Audi A8 is loaded, it will undoubtedly affect Audi's cost control. In any case, Audi wants to continue to use sales to crush Mercedes and BMW, and it will have to work harder on the transmission.
