Alfred Bock, the operator of Block Busreisen, was awed by Setra buses when he was young, but he is now using the touring bus for his business. He did not hide his enthusiasm for the S517 HD during the official handover in Neu-Ulm. He said that the faith that his company has on the engineering of the bus and the camaraderie with the sales team typify the cooperation between his company and the brand.

Alfred Bock did not think twice in favoring the next-generation last summer even without test-driving it. The S517 HD is the initial touring coach for the ComfortClass 500 series that was delivered to North Germany from Daimler AG. The S517 HD allows 52 passengers to sit comfortably on a chair-like seat that provides a good amount of legroom. Each seat has armrests, footrests, and passenger tables. The headroom of the interior is at 2.1 meters, which allows tall passengers to sit comfortably anywhere in the vehicle.

The S517 HD is a 3-axle model that uses the Euro VI engine. This particular engine is friendly to the environment. It comes with a galley, audio and video systems, and a number of safety features. One features included is an adaptive cruise control that has an emergency braking assistance.
