The Mercedes-Benz W03 was a large six-cylinder-engined automobile introduced as the Mercedes-Benz 12/55 PS and, initially, as the Mercedes-Benz Typ 300, by Daimler-Benz at the Berlin Motor Show in October 1926.
It was developed in some haste under the manufacturer’s Technical Director, Ferdinand Porsche in parallel with the smaller Mercedes-Benz W 01 (which never progressed beyond the prototype stage) and the two-litre-engined Mercedes-Benz W02 following the creation of Daimler-Benz, formally in July 1926, from the fusion of the Daimler and Benz & Cie auto-businesses.
