Critical requirements of Automatic Transmission in Chinese auto market 中国自动变速器市场需求分析

中国汽车市场对自动变速器的关键要求–Low cost 低成本

–Low fuel consumption 低油耗–Small input torque 低输入扭矩F t li ti –Front-cross application 前置前驱–High shifting quality 高换挡品质

–Low speed drive in long time 长时间低速行驶–Mature technology gy 成熟技术

A small 8AT with a conventional hydrodynamic torque A small 8AT with a conventional hydrodynamic torque converter may be a good option for such cars 具有8个档、低输入扭矩、带有液力变矩器的传统自动变速

器将是不错的选择
