It’s not unusual for car manufacturers to test weird and wacky creations with no intention of turning them into production cars, but these two Mercedes-Benz S500s have caught our attention.

For the most part, the two prototypes seen secured on a transport truck, appear like any other S-Class. However, on further inspection, you’ll notice that both have been equipped with flared wheel arches which resemble something you’d see from Liberty Walk, not Mercedes-Benz.

It is difficult to know what the German automaker is working on but it is possible that these fenders have been fitted to help the car accommodate a set of wider wheels. If that’s the case, then it is possible that they offer an early taste of a future S-Class AMG model, potentially a straight-six model dubbed the S43 AMG.

What is also interesting about the two prototypes is that they’re based around the pre-facelift S-Class and could, therefore, be leftover mules from testing of the updated S-Class.

Do you have any thoughts about the prototypes? Let us know below!
