Why is the Blue Whale 1.4T engine of Changan Automobile not worthy of Aisin 6AT gearbox?

In the global low-cost automatic gearbox, Aisin 6AT gearbox must be regarded as a benchmark product. In the past many years, this gearbox with smooth shifting and slight setback has been considered as the best Toyota engine? Partner? There is none. Compared with ZF and other world-famous automatic gearboxes, the bulk purchase cost of Aisin 6AT is relatively small. Under such circumstances, it can also provide a good gearbox experience for vehicles, so Aisin 6AT gearbox was quite hot in the domestic market for some time.

Perhaps before this year, Aisin 6AT was worshipped by independent brands, and many important products of domestic first-and second-tier manufacturers such as Changan and Guangzhou Automobile Chuanqi used Aisin 6AT gearboxes. A few years ago, it even came out that Toyota was worried that the sales of Chuanqi GS8 would surpass Highlander, so it ordered Aisin (Toyota Holding Aisin) to reduce the supply of GAC Chuanqi 6AT gearbox. Mandatory? Reduced the sales of Chuanqi GS8. Of course, it seems a bit like a joke now, and we don't think this situation exists. But on the whole, Aisin 6AT was really deified by its own brand in previous years.

However, since 20 19, many models previously equipped with Aisin 6AT have gradually turned to other gearboxes, such as Changan Automobile, the second generation Yidong and Changan CS35PLUS, which were originally equipped with Aisin 6AT gearboxes, but the 1.4T models of Yidong Blue Whale Edition, Yidong PLUS and CS35PLUS Blue Whale Edition have all been replaced with dual-clutch gearboxes, and the 6AT models have been compressed to a very low level. That is to say, the CS75 Plus/KOOC-0/.5t model, the CS95 without a brand-new model still uses the 6AT gearbox, and the gearbox of the/KOOC-0/.5t model, such as the CS85 Coupe, has also become a dual-clutch gearbox.

So is Toyota. As the controlling shareholder of Aisin, Toyota naturally has the priority to use Aisin 6AT gearbox. However, we can see that some Toyota models have begun to give up Aisin 6AT gearbox, such as the brand-new lexus ES, which was equipped with 6AT gearbox when it was first launched, but it was slightly changed, that is, the current models were also replaced by CVT gearbox, and the situation of Camry was similar.

Moreover, Aisin had previously established a joint venture company with Geely and GAC in China, but we can see that both Geely and GAC's main models still have nothing to do with Aisin's best 6AT gearbox. The overall popularity of 6AT among independent brands seems to have lost its former glory in a year or two. What's the problem?

In fact, for manufacturers who still trust Aisin, although? Abandon? After 6AT, 8AT gearboxes with better comprehensive performance were ushered in, such as Camry's 2.5L model, Changan CS75 PLUS's 2.0T model, Geely Xingyue's 2.0T model and so on. Therefore, Aisin gearbox is still one of the safest choices for independent brands to reflect the reliability of core components. However, domestic manufacturers have chosen the combined assembly method, with high/large displacement vehicles matching Aisin 8AT gearbox, and low/small displacement vehicles equipped with CVT gearbox or dual clutch gearbox with lower cost, which is more conducive to the cost control of sports vehicles.

On the other hand, although 6AT has better ride comfort and torque tolerance, compared with CVT gearbox and dual clutch gearbox, fuel consumption is always a big problem. At present, the main sales models of many manufacturers are equipped with small displacement engines or three-cylinder engines, which actually require higher fuel consumption. Aisin 6AT gearbox basically has no advantages, and the purchase cost is high, and sometimes it is worried that the supply can't keep up, so many domestic manufacturers adopt CVT gearbox and dual clutch gearbox with lower cost but better fuel consumption.

In short, with the continuous progress of gearbox technology, the era when Aisin 6AT gearbox was absolutely suppressed by seconds, especially the dual-clutch gearbox, was regarded as the era of conscience and advanced matching, and it seems that it has passed. Most manufacturers who value AT gearbox and want to improve the product height choose Aisin 8AT gearbox, while most of those cars with small displacement choose dual-clutch gearbox and CVT gearbox with lower cost, so the significance of 6AT gearbox is not so obvious. So now Aisin 6AT gearbox is sandwiched between its own 8AT and other brands of dual clutch /CVT gearbox. It may not be long before Aisin 6AT is replaced by various 8AT, 9AT and 10AT gearboxes.
