通用的8AT还在图纸上吧233

根据MOTOR TREND的新闻稿GM投资了2亿刀建厂，本来预计是今年能出来的但是好像产品没赶上计划所以和爱信签了个短期协议，明年开始会换上自己的8AT。

有人说北美的油耗标准不太高，GM没动力上8AT……

如果这个文的内容属实，这8AT变数很大，很可能长期纸面化

这文还说GM的8AT设计上不能搞定高扭，所以14款CTS Vsport只好用了爱信的233

哦，原来还是爱信的，了解了。

根据MOTOR TREND的新闻稿GM投资了20亿刀建厂，本来预计是今年能出来的但是好像产品没赶上计划所以和爱信签了个短期协议，明年开始会换上自己的8AT。

通用不是已经在弄9AT和10AT了，怎么还要搞8AT？这不是浪费吗？

可能是实用的扭矩范围不一样吧，9AT前驱专打小轿车，8AT后驱打皮卡和普通性能车，10AT打卡车和高级性能车？

北美的油耗测试普遍比欧洲高啊

欧洲那纯粹投机倒把的测试方法……

9AT是横置引擎用的，10AT是纵置引擎用的，这两台新闻稿说是要2016年才能面市。
但是通用这两年有很多重量级的车，比如克尔维特C7、CTS还有旗舰LTS，继续用6AT有点跟不上节奏等那个10AT又有点太慢了，所以投了2亿刀建了厂搞纵置8AT只是没顺利大规模量产。

GM announced that it will invest an additional $2 billion into several of its U.S. assembly and component plants, including $204 million into its Toledo powertrain plant. The cash invested there will be used to manufacture an all-new, advanced eight-speed automatic transmission for future vehicles. The automaker says that this tranny will offer "improved fuel economy and outstanding performance."

The report says GM wanted to make sure it has all of the bugs worked out of its in-house-developed transmission before it launches, so it's doing a short-term agreement with the Japanese transmission supplier. Since GM is developing its own eight-speed for use in transverse (front-wheel drive) and longitudinal (all- and rear-wheel drive) applications, the Corvette will share its transmission with cars like the Cadillac XTS, ATS and the next-gen CTS, while the Buick LaCrosse and new Impala will be likely candidates for the transverse version of this gearbox.
