The Mercedes-Benz W10 is a 2/4-door roadster / 4-door saloon / 4-door limousine from Mercedes-Benz, built from 1929 to 1934, the vintage years, when coachbuilders still shaped most of what was sold. Under the bonnet: 3.4 L M10 inline-six engine. Hans Nibel drew it.
The background
The Mercedes-Benz W10 was a touring car produced by Mercedes-Benz from 1929 to 1934, replacing the W03/Typ 350 models. The structure originated by Ferdinand Porsche was modified by Hans Nibel.
The engineering
Power comes from 3.4 L M10 inline-six engine; other versions carried different engines, listed in the specification table below. It shifts through a 3-speed manual. The layout matters: a front engine drives the rear wheels, the classic proportion — long bonnet, cabin set back — that most people picture when they picture a sports saloon or a grand tourer. The wheelbase is 3200 mm (350, 370, 380S) / 3030 mm (370K) / 2850 mm (370S). These are manufacturer figures carried by Wikipedia and Wikidata, not road-test measurements.
Where it sits
Its family tree is legible: it took over from the Mercedes-Benz W03; its successor was the Mercedes-Benz W18; assembly was at Stuttgart, Germany. Its contemporaries in the catalogue — the Lancia type Dilambda torpedo, the Lancia Lambda torpedo, the Bugatti type 40 coupé — show what else the money bought that year. Its Mercedes-Benz stablemates include the Mercedes-Benz 300 SL and the Mercedes-Benz C124.
What it costs now
There is no federal ownership record for the Mercedes-Benz W10 — 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.
