Over the past two decades, the German powerhouse known as Mercedes-Benz gave the world a plethora of elegant sedans and neat high-performance machines. The development mule caught by our spy photographers a short while ago leaves us perplexed, though, chiefly because nobody knows what it is.
From the looks of it, this appears to be your typical Mercedes-AMG S63 Coupe. But then you focus on the proportions of the development mule, and it comes to you: why is it shorter than a regular S63 Coupe, like, a lot shorter? I am just as confused as you are. Still, let’s start analyzing what we have here, detail by detail.

For starters, the mock-up body shell appears to be done by professionals. Then there’s the shorter wheelbase, which is trumped by the Mercedes-AMG S63 Coupe at least 15 centimeters (5.9 inches). The greenhouse differs too, as does the raking of the windshield. As for the cabin, it’s plain to see that there’s no difference between it and the regular model’s dashboard.

Our spy photographers have confirmed that the burble coming out of the quad exhaust system is the sound of a twin-turbo V8, albeit it’s hard to pinpoint what twin-turbocharged eight-cylinder engine we’re dealing with. More to the point, it’s a guesswork game between the 5.5-liter M157 and the 4.0-liter M178.

Based on the details identified up to this point, I’m betting my two cents on the 2020 Mercedes-Benz SL-Class. According to more or less official reports, the next-gen SL will be underpinned by the lighter and more rigid Mercedes MSA platform, with MSA being the acronym for Modular Sports car Architecture. The MSA platform is also expected to act as the backbone of the next-generation SLC-Class.

Supposition aside, the question persists: what do you think we have here?
