On May 29, 1921, Max Sailer drove the Mercedes 28/95 hp Sport under the piercing Sicilian sun for a little less than seven and a half hours to complete the Targa Florio. Sailer claimed second overall, the fastest lap time, and a class win in the touring cars over 5 liters. 

He drove for more than 432 kilometers against remarkably formidable competitors who were mostly Italian drivers.

The 1921 Targa Florio race was held on a 108-kilometer circuit at the north of the Italian island on unpaved mountain roads. Drivers were required to complete four laps of the challenging track which contained around 1,500 bends, and an 800-meter altitude change.

Since the race’s beginning in 1906, the 1921 Targa Florio was considered to be the first edition of the road race where professional works teams competed for the first time.

Daimler-Motoren-Gesellschaft (DMG) had two of their 28/95 hp Sports cars sent to Sicily. The challenge commenced even before the race began as Max Sailer himself drove his racing car to Sicily. Even though the distance to Sicily was 1,300 kilometers away as the crow flies, it became 2,000 kilometers on the road. However, this practice was rather normal in motorsport at the time.  

Adding to the challenges were high temperatures and dust, as well as the great risk of tire punctures from hoof nails littering the road. In fact, it was this very same risk that hindered them from claiming the overall victory. In a sales bulletin from DMG on June 6, 1921, it stated: 

“Sailer had to change tires nine times, while the absolute winner of the Targa, who arrived just two minutes ahead of him in a special Fiat racing car, did not have a single flat tire.” 

What was remarkable was despite the nine punctures, the Stuttgart-bred racing driver was able to complete the Targa Florio in 7 hours, 27 minutes, and 16.2 seconds, running an average speed of 57.9kph.

To manage the grueling conditions of the Targa Florio, Sailer was fortunate to rely on a new technology: the Mercedes 28/95 was the first Daimler-Motoren-Gesellschaft (DMG) vehicle that incorporated four-wheel brakes.

The new system had provided a noticeable improvement in braking power, resulting in improved driving safety and precision. The brakes used were drum brakes which were visible behind the wire-spoked wheels. 

The Mercedes 28/95 hp Sport success with four-wheel brakes’ is an excellent example of how racing directly affects new vehicle technology.

Starting June 1921, the 28/95 hp Sport was added to their range of standard models available. Their successes at the Targa Florio became a great marketing tool for the model.

A Viennese car dealer, Mercedes Auto-Palast, had a full-page ad in the Austrian “Allgemeine Automobil-Zeitung” dated November 6, 1921, with the slogan “Seven races-seven victories!” The ad also announced the arrival of the model, saying, “Six-cylinder model 28/95 hp, 1921, has arrived!” 

From 1923, the production version of the top model 28/95 hp was also equipped by DMG with the “all-wheel brake system”.

In time, the four-wheel brake system was adopted as a standard in automotive engineering all over the world.

The difference in performance between the rear axle brakes and the four-wheel brake system was so enormous that in the mid-1920s, there was actually a discussion in Germany on establishing a warning sign on these vehicles to warn the other road users ahead of time. On September 12, 1925, the “Allgemeine Automobil-Zeitung” reported this with the headline, “Caution, four-wheel brakes!”

The Mercedes 28/95 Sport was the next step in the high-performance luxury vehicle evolution. Before the First World War, Paul Daimler designed the Mercedes 28/95 and unveiled it in 1914. 

The Mercedes 28/95 was equipped with a 66 kW (90hp) in-line six-cylinder engine that had a 7,280cc displacement, an overhead camshaft, and overhead valves that were arranged at an angle.
