That would've most likely see the Coupe incarnation of the new Z4 rivaling the 2020 Supra, but let's not dwell on such battle dreams for too long.
Instead, we can focus on the form the said Bimmer would've taken. In fact, I've brought along a rendering portraying a concept car that would've previewed the showroom material.
For added drama, Max Shershnev, the transportation designer behind these pixels, showcases the machine doing its thing outside the beaten path.
But if we look past the rally-style dirt, we'll notice the styling cues of the proposal, which seem to fall in line with BMW's current design language.
Now, if you're not convinced of the conclusion above, you can simply compare this rendering to the Concept 4 that recently bowed in Frankfurt, previewing the future 4 Series - you'll find a live photo gallery above.
And yes, this is yet another implementation of BMW's new-age, super-sized kidney grilles. Well, as in the case of the said concept car, the idea seems to work much better on this Z4 than on the luxobarges that feature it in real life, namely the 7 Series and the X7 seven-seater.
Given the fact that the German automotive producer continues to be an explorer of styling languages, perhaps we'll get more super-sized grilles on sportscars in the future.
