That is one sweet Mercedes, although I'm not partial to red.

Mercedes-Benz 150 (W30)

The Mercedes-Benz 150H was a prototype sports racing automobile built in Germany in the 1930s.[1] It was derived in 1935 from the 130 with only two seats and a more powerful engine, with 1498 cc and a power of 55 PS (40 kW). The top speed of the car was 125 km/h.

Conceived by Hans Nibel, chief engineer of Mercedes-Benz,[1] the 150H was inspired by Edmund Rumpler's Tropfen-Auto. It followed on the Rumpler-chassis Tropfenwagen racers, which ran between 1923 and 1926,[2] and was based on the backbone chassis of earlier 130H.[1]

Edit: Not air cooled.

While the 130 had a 1.3-liter, water-cooled four hung out behind the rear axle, the 150's 1.5-liter four was turned around 180 degrees, its midships location giving the chassis better balance and more stable handling. In place of the 1.3-liter's sidevalve arrangement, the 1.5 had overhead valves, and produced about 55 horsepower with a Solex two-barrel carburetor and a compression ratio of 7.1:1.
