      O/D 按键..,按下后.,也就是激活后会显示的是 o/d off  也就是overdrive off..,
      一般有这个键的车都只有1个overdrive..,所以就是最高档位不可用..,5挡车..,变速箱只工作在1-4档.,4挡车只工作在1-3档..,对扭矩.,功率什么的没有任何影响

      那你说这个车有3个超比挡了..?..


      With the popularity of front wheel drive cars, the separate gearbox and final drive have merged into a single transaxle. There is no longer a propeller shaft and so one meaning of "overdrive" can no longer be applied. However the fundamental meaning, that of an overall ratio higher than the ratio for maximum speed, still applies.[1] Although the deliberate labelling of an overdrive is now rare, the underlying feature is now found across all cars.



      现在标着od off的车有很多是前驱车...,但是1:1在前驱车上面已经不适用了..,适用的是: However the fundamental meaning, that of an overall ratio higher than the ratio for maximum speed, still applies..
      这也就是od的基本定义..
