Mercedes-Benz does not build many cars like the Mercedes-Benz W06 with supercharged SOHC I6, built from 1926 to 1933 the vintage years, when coachbuilders still shaped most of what was sold. Its designer of record is Ferdinand Porsche.
How it came about
The Mercedes-Benz S-Series (W06), nicknamed "the white elephant", was a successful line of sports cars produced from 1926 to 1933.
The hardware
Under the skin sits supercharged SOHC I6. The layout matters: the engine sits behind the driver and ahead of the rear axle, which puts the mass in the middle of the car and is why mid-engined cars change direction the way they do. These are manufacturer figures carried by Wikipedia and Wikidata, not road-test measurements.
Family and rivals
Where it sits in Mercedes-Benz's history is not in doubt: it was built at Bremen, Germany. On a showroom list of its day it stood against the Rolls-Royce Phantom I sedan, the Fiat 521, the DKW Typ P. Its Mercedes-Benz stablemates include the Mercedes-Benz 300 SL and the Mercedes-Benz C124.
The money
There is no federal ownership record for the Mercedes-Benz W06 — it predates the complaint database or was never sold in the United States — so MotorJury publishes no running-cost figure for it. For a car of this age the price is set by the collector market and the condition of the individual example, not by a formula.
