但这需要很多年时间，而且必须与真正的车身轻量化结构有效结合，而这正是奥迪毋庸置疑的核心技术之一。

But this will take many years, and then will only function really effectively in conjunction with rigorous lightweight construction technology - one of our undisputed core skills.

针对这个挑战，我们提出的极轻量化结构，以及能被轻易地拆分为众多组件的结构，使得将其运到所在地成为可能。

The design responded to this challenge by proposing an extremely lightweight structure and a structure whihc can be divided in components easily so that the transport to the site became possible.
