The Opel 4/8 PS or known as the doctor's car (Doktorwagen in German) is an automobile from the German automaker Adam Opel KG.
The Opel 4/8 PS was built especially for the middle class. The two seater was small and agile compared to other cars of this time and was used by many doctors for house calls, so the vehicle quickly got the nickname "Doctor's Car". The low price of 3,950 Mark made it a very successful model.
The doctor's car was the first car from Opel, which bore the Opel lettering on the radiator.
Opel campaigned for the Type 4/8 PS (hp) with statements, such as "Simple mechanism", "Incredibly easy to use", and most of all: "Without using a chauffeur".
The Opel 4/8 PS is driven by a water cooled four cylinder engine with a displacement of 1029 cc. The performance is eight horsepower, reaching a top speed of 60 km/h. It was for that time sufficient.
