Accordingly, with the 540 K Streamliner, the most recent developments in aerodynamics were applied: the aluminium body was magnificent with its flowing lines, its low-level silhouette, a minimum of protuberances on the surfaces and a panelled undercarriage. Even the classic Mercedes star was not upright above the radiator, but to reduce wind resistance was painted on to the front of the bonnet. And the prestigious Mercedes-Benz pointed radiator had disappeared behind a streamlined front which for its time was a particularly avant-garde style element. In short, the design of the 540 K Streamliner was based faithfully on the knowledge of aerodynamics of its day. With its powerful compressor charging, the car quickly reached high speeds which it was able to maintain for long distances.
