What do rock formations, whales and haute-couture have in common? The Mercedes-Benz S-Class Coupe concept, apparently. While we thought we knew what to expect from a two-door S-Class, the sexy coupe actually has way more going on than we thought, which we found out after the car's worldwide debut at the Frankfurt Motor Show.

Mercedes frequently uses the phrase "sensual clarity" to describe the concept's take on modern luxury - and there's no doubt that the S-Class Coupe concept is both modern and luxurious. This is first demonstrated by the exterior, which is defined by smooth surfaces and a razor-sharp contour similar to what we've seen on the CLA. Further validating this claim is the concept's three-dimensional diamond grille, which also taken from the much smaller four-door. That's not the only model the concept takes after. In fact, the concept draws from the entire Benz gene pool for other styling details, such as the one-strake grille found on the CL AMG, CLS, and E-Class coupe. While the full LED headlights aren't anything different from what we've seen before, the shape of the integrated light strips are a tad different; on other models, they're angled off, but on this concept, they have a circular shape.

From the side, the concept looks stunning. Its sleek roofline appears almost flat as it fades into the rear and the chrome trim outlines of the side windows and frameless doors provide the appearance of one large sheet of glass, hiding the B-pillars.

Many of the S-Class Coupe Concept's 198.8 inches of length are found up front thanks to the long and distinctive hood that reminds us of the SLS AMG GT. More similarities with the exotic appear around back, as the license plate surround was moved to the lower bumper section so the three-pointed star can sit right smack in the middle of the trunklid -- again, just like the SLS. Above the badge is a chrome strip that connects and extends over two slim taillights, which Mercedes says is a throw back to earlier models. Compared to the S-Class Sedan, the concept is 7.7 inches shorter in length and 3.2 inches shorter in height.

Inside, it's a white out. Keeping in line with the "sensual clarity" theme, the instrument panel has a curved shape "reminiscent of a whale's fins just before it re-enters the water." We don't quite understand what the automaker means by that, but if anything inside the cabin looks even remotely close to a cetacean, it'd be the white calfskin front seats since they have vertical piping resembling the mammal's throat grooves. Aside from that, seats are super-sculpted, inspired by the haute-couture fashion, which is all about exclusive custom-fitting clothing.

Back to the instrument panel (also made from calfskin), new air bag packaging allowed designers to create a wavelike effect. This makes it look as though the panel fades into the side door panels, which are also something entirely different. Inspired by rock formations in Utah, panels have slim topographic lines milled into the metal, while lots of tiny perforations surround the loudspeakers. Sandwiched between the instrument panel and dashboard are the S-Class sedan's 12.3 inch touchscreens, though in this application, they're slimmer. And while analog clocks are usually a nice old school touch in luxury cars, Mercedes puts a new school spin on them with a touch screen display that shows four world clocks so you'll always know what time it is in Tokyo, Moscow, or whichever time zones you choose. The center console is made of a "black diamond" surface that is highly scratch resistant, while black leather floor mats have the same piping as the seats. To top it off, the headliner is made out of hand-woven silk.

The concept is equipped with all the S-Class goodies, which includes all the radar, sensors and cameras that make up Intelligent Drive. Although you get to treat your nose to the Active Perfuming System, the concept is equipped with MoodGrid software, which selects music based on the driver's mood. Underneath the hood, the S-Class Coupe houses a twin-turbo V-8 engine that produces 449 hp and 516 lb-ft of torque, which sounds like the same mill found in the S500.

Now that you've gotten a little more familiar with the S-Class Coupe concept, are you sensually clarified?
