Blame Mercedes for starting the modern coupe/sedan mashup trend with the 2004 CLS, a car that won over the public for its stylish low coupe roofline and four-door functionality. BMW soon followed with the 6 Series Gran Coupe and now, Audi has joined the party with its A5 Sportback, the automaker's answer to the BMW 4 Series Gran Coupe. We admit that the upcoming 2017 rendition of the car looks good, but we'd be even happier if it came with more power. Thankfully, rendering artist Theophilus Chin has used his talents to show us what that might look like.

Unfortunately, BMW doesn't have a 4 Series Gran Coupe that's been tricked out by the M Division. But if Audi brings the hardware it's currently testing for the RS5 to the Sportback, you can be sure that BMW would follow. Those seeking a stylish Audi sedan with a coupe-like silhouette and horsepower numbers large enough to render it a world superpower already have the RS7 to turn to. However, while fast, the RS7's sheer size makes it a comfortable cruiser that's at home doing triple digit speeds on the Autobahn more than turning around record lap times at the Nurburgring. That could easily change, though. Audi is currently testing the new RS5 with engines stolen from one of the Nurburgring's fastest sedans, the Porsche Panamera.

This makes it easy to imagine an ambitious lead engineer signing off on the RS5 Sportback with a swoop of a pen and giving BMW M and Mercedes AMG reason to lose sleep at night. In this rendering, Theophilus Chin has spent the most time blacking out many of the chrome elements on the car, a tactic that automakers typically use to make models look angrier. At the rear, the miniature RS7 gains a diffuser and replaces the quad exhaust with two large diameter exhaust tips. The brakes also see an upgrade, but after that, the differences end, lending somewhat of a sleeper image to the RS5 Sportback. While the automaker hasn't made mention of an RS variant of the A5 Sportback, we can dream and imagine all we want.
