Chinese electronics giant Xiaomi has introduced its first in-house electric car. But contrary to its image as a maker of budget-centric devices, the company’s first electric car, the SU7, is looking straight at the likes of Tesla and Porsche.

But those comparisons are not hollow, and some of its capabilities sound really impressive.
