Wednesday 10th December 1924
The new Mercedes 15/70/100 hp (and 24/100/140 hp) cars with 6 cylinder supercharger engines were presented at the Berlin Automobile Show. Model names were derived from the widely followed German naming conventions of the time. Thus for Daimler’s Mercedes 15/70/100 PS the “15” defined the car’s tax horsepower, used by the authorities to determine the level of annual car tax to be imposed on car owners. The “70” and the “100” both defined the manufacturer’s claims regarding car’s actual power output as defined in metric horsepower.
