The Mercedes Simplex was designed by Wilhelm Maybach in Stuttgart, Germany. It featured powerful engines whose power ranged from 40 to 60 hp. Its large and wide body had a low center of gravity. A highlight of the simplex family was the model 60 hp. With this car Mercedes laid the foundation of a new car segment, the super-luxury class with an imposing touring Saloon body, it was unlike anything else at the time and quickly established itself well with royalty and aristocrats. Its immense size and luxuries were to set the milestones for the development of this segment, which was continued on by numerous models over the next 70 odd years, including the 630, 770 Grand, 300 Adenauer and terminating in 1981 with the demise of the 600 Grand. All these models occupied the absolute top segment in the automotive world along with brands such as Rolls Royce, Bentley, Cadillac and other demised car manufacturers.
