Downshifts in overrun state are accomplished with very little intermediate throttle application and are thus hardly audible .

在超速状态下，可以在极少使用中等节气门的情况下完成降档，从而几乎不发出任何声音。

Gearshifts are performance-oriented and the engine torque is not reduced during upshifts and downshifts .

在升档和降档过程中，换档操作将以性能为导向，且发动机扭矩不会减小。

There were dozens of hairpins and switchbacks along coastal inlets that required downshifts to second gear , followed by lusty acceleration up to the top of the next hill .

在沿海公路弯道上，不断出现高高低低、蜿蜒曲折的路，这就要求汽车忽而降到二档，忽而全速冲上山头。
