Why do Highlander and Overbearing use 6-speed manual, while others don't?

In addition to at, there are two automatic gearboxes, dual clutch and CVT. Toyota is not good at using dual clutch, or it can be said that it does not master advanced dual clutch technology. So the gearboxes used are mainly CVT and at. The main advantages of CVT are economy and fuel saving, and its power transmission and durability are not as good as at's. It is precisely because of its low cost that it seems to be the representative of the low end. In fact, it is mainly used in some low-priced models of Toyota. At gearboxes, especially Aisin's 6at, are well known. Its performance and durability are very comprehensive. Why do Highlander and Overbearing use 6-speed manual integration?

Vehicle positioning determines that as an urban SUV and hard-core off-road vehicle, Highlander's overbearing positioning is biased towards sports and requires low-speed off-road. Relatively speaking, only at gearbox meets the positioning requirements of vehicles. Especially for low-speed power supply, there is a strong demand. 6at can bear enough torque. At present, there are only three kinds of gearboxes in the market: AT, CVT and DCT. Among the three types of gearboxes, only at gearbox can bear the maximum torque, while 6at can bear the maximum torque of 700 Nm. However, the bearing torque of CVT is too small to drive such a large body. Although the bearing torque of the dual clutch is large enough, it is definitely impossible for Toyota to use this popular product. Aisin, as a subsidiary of Toyota Holdings, uses its own products, with lower procurement costs and higher natural profits. Aisin 6at products have stable quality and high market popularity. Especially after the patent protection of 6at expires, the purchase price is lower, the merchants pursue profits, and the price is lower, which can meet the requirements. The adoption of 6at is naturally obvious.

Highlander and overbearing belong to Toyota's mid-to high-end models. According to the characteristics of Toyota, we must first ensure the quality is reliable, and then consider the performance. They have enough strength. Especially overbearing, as a hard-core off-road vehicle, it requires high torque resistance of the gearbox, which is a major deficiency of CVT gearbox. Therefore, it is more reasonable to use 6at with better performance. Some people may ask why not use 8at? This must be considered separately. In fact, for Highlander, 6at is very competitive among its peers. For profit-seeking manufacturers, 8at is not needed at present. As overbearing is a hard-core off-road vehicle, the performance of 6at in dealing with various complicated road conditions is not necessarily worse than that of 8at, and the structure is more complicated, so both of them adopt the most mature and reliable 6at gearbox of Aisin at present.
