The key to coasting is to build up as much speed as you can before cruising on the straight parts of the road.

滑行的关键是在稳稳当当地行使在道路笔直部分前尽可能增大速度。

youdao

Coasting reduces mechanical stress because you use the momentum you gain from building up speed to keep the car moving forward.

滑行减少了机械压力，因为你是利用由加速获得的动力使车前行。

youdao

A coasting performance test is simulated on a chassis dynamometer, the transmission resistance, rolling resistance of wheels and their speed factors are measured.

利用底盘测功机模拟道路滑行试验，测定出汽车的传动系阻力、轮胎滚动阻力及它们的速度影响系数。

youdao

So, you picked up some speed, then you're coasting along at a steady speed.

所以当你加到一定速度,然后你便匀速上升的时候

Flooring the accelerator got us up to speed nimbly, but coasting wasn't an option as traffic became more congested in spots.
