Mercedes-Benz 150 is First Produced
The Mercedes-Benz 150 was derived in 1935 from the 130 with only two seats and a more powerful engine, with 1498 cm³ and a power of 55 PS (40 kW). The top speed of the car was 125 km/h. The car was only offered as a Sport Roadster.
The gas tank, which in the case of the Mercedes-Benz 130 was installed over the engine, was transferred to the front compartment, and therefore there was no room for luggage there. The practicality of the 150 was therefore very limited, and the price of the car was quite high at 6600 RM ; as a comparison the Mercedes-Benz 170 V had a price of 5500 RM. The car was discontinued in 1936 due to poor sales.
At the beginning of the 1930s, inspired by the modern streamlined shape, there were attempts to move the engines from the forward compartment to the rear of the car. Such a move allows to decrease the volume of the front compartment. At the same time, the voluminous rear provides a lot of space above and behind the rear axle. Moreover, when fitted on the drive axle shaft were eliminated. The most famous such development was with the Tatra cars under the leadership of Hans Ledwinka.
In 1930, Daimler-Benz AG entrusted Hans Nibel with the development of a small rear engine car based on the same principles. In 1931 the type W17 or 120 was created, a four-seat, equipped with two doors, vertical front and rear wheels and a four-cylinder boxer engine in the rear, with a displacement of 1200 cc and a power of 25 hp (18.4 kW). There were also attempts to row across built four-cylinder engines. In 1933 Mercedes built a vehicle with a front similar to the VW Beetle later and a far extensive tail. The front wheel of the type W25 D or 175 is slanted or tilted backwards, in the middle of the tail fin attached hood divides the oval rear window, so it anticipated the small oval two piece rear window of the Beetles known as "pretzel form". The "D" referred to the three-cylinder diesel engine OM 134 with an output of 30 hp (22 kW), but due to high noise level, this vehicle was again rejected. From this type, 12 test cars were assembled.
From 1931 to 1939, Daimler-Benz AG produced three cars (Mercedes-Benz 130, 150 and 170 H) with rear engine as well as a few prototypes. The production numbers remained quite low for each of these models, especially compared to the production of classical front-engine Mercedes cars.
