Mercedes didn’t team up with Benz until 1926. But before that, Emil Jellink’s Mercedes produced some fine cars. Finer than most Benzes. Mercedes launched the 10/40hp in 1921 and would update it to the 10/40/65hp in 1924, the model’s final year of production.

Power is provided by a 2.6-liter inline-four that was rated at 65 horsepower with the supercharger engaged. This car was sold new in Germany and remained in Romania from essentially new until 1989, with about 30 years of that on museum duty.

It was 1989 that it came back to Germany and then the U.S., where it was restored in 1991. It was originally bodied as a cabriolet and now wears “SSK-lite” sports bodywork. It has an estimate of $100,000-$180,000. Read more here.

This pretty Mercedes touring car was built by Mercedes – before the “hyphen Benz.” In fact, it was produced just two years before Daimler (Mercedes’ controlling company) merged with The House that Karl Built in 1926.

The confusing model nomenclature used by Mercedes with the three numbers separated by slashes is like that for good reason: these were the first production cars fitted with superchargers and the numbers reflected the horsepower during various driving stages. The first number is the nominal horsepower (which was and is an outdated way of estimating power – it’s what they used for steam engines), the second number is the engine during normal operating procedure, and the third is when the supercharger is engaged.

So this 2.6-liter straight-four put out 40 horsepower – 65 when the “Kompressor” was engaged. It was the more powerful of the two four-cylinder cars Mercedes was producing at the time. My favorite part of the catalog entry for this car is that this car is currently owned by a collector of mainly post-war Mercedes and this car “does not fit his collection.” Must be a nice problem to have.

Only 851 10/40/65s were built. And this one should sell for between $610,000-$890,000. Click here for more info and here for more from this sale.
