lose speed

Once cars lose speed and power, they become unglamorous everyday tools, like washing machines, and nobody, presumably, derives status from their washing machine.

一旦汽车失去了速度和超强动力，它们就变成了洗衣机似的单调乏味的日用工具。我想，没人靠洗衣机体现自身社会地位。

We lose speed, but we should gain in strength and size.

我们失去了速度, 但是我们应该在力量和卡位上有所增强.
