At first we couldn't understand why the BMW X6 was birthed, and then we couldn't figure out why Acura of all companies needed to create something to compete with it. Top Speed has rendered unto us what such an enigma might look like, and, well, it ain't all bad. That's probably because it looks like an MDX with a descending roofline out back. Of course, it's impossible to know how much of any rendering is pure fiction, but The Majestic Shield of Acura matched with those lights and a proper amount of real estate could be the ideal pairing of design features and suitable canvas.

Auto Express has brought its resources to bear and cooked up a pair of renderings of what form it thinks the new micro-car could take.
