In 1937, the Mercedes-Benz 320 (factory code W 142) emerged as a successor to the aging 290 model, arriving during a period of somber and challenging times. However, this “flawless German” automobile had the remarkable ability to inspire a sense of joy and optimism.

Despite not being the priciest option in Mercedes’ lineup during the late 1930s, the Mercedes-Benz 320 was far from being classified as affordable either. It showcased an impressive array of steel and chrome, along with exquisite woodwork and luxurious leather upholstery. The attention to detail was meticulous, evident in even the smallest aspects, and the vehicle boasted two spare tires. The manufacturer opted for natural materials, eschewing synthetics, and inexpensive components, emphasizing grandeur and perfection on a grand scale. The bare chassis without a body carried a price tag of 6800 RM (Reichsmarks) or $17,000, while the cheapest sedan model was priced at 8950 RM or $22,380. However, the convertible commanded a substantial premium, costing 13,500 RM or $33,750. To put things into perspective, a six-cylinder four-door BMW 326 retailed for 5500 RM ($13,750) at the time, while the Opel Kadett was a more affordable option, priced at only 2100 RM (5250).

The Mercedes-Benz 320, belonging to the W 142 series, made its debut at the International Motor Show (IAMA) held in Berlin in February 1937. It served as a replacement for the 290 model, which was a mid-range vehicle produced at the Stuttgart plant. With the introduction of this new model, Mercedes-Benz aimed to bridge the gap between their mid-range cars and the larger, more luxurious models. This release was significant for the brand, as it entered a highly competitive vehicle class. Notably, their main rivals at the time included Horch with their 930 V and 830 BL models, Opel with the recently launched Admiral, and Ford with its 3.6-liter V8. Initially, the manufacturer offered two different wheelbase options for the Mercedes-Benz 320. It was an evolution of the 290 (W 18) model, which had been available from 1933 to 1936. The focus during the development of its successor was on enhancing engine performance and ensuring smooth operation, while still retaining the concept of a side-valve six-cylinder engine with vertical valves. The M18 engine of the 290 models had a modest output of 68 horsepower (50 kW), resulting in moderate driving performance. However, when the engine was revised for the Mercedes-Benz 320, significant improvements were made to achieve higher power output. In general, the positioning of each vehicle within Mercedes-Benz’s lineup during the 1930s was determined by the number of cylinders and the engine size. Among the three mid-range six-cylinder models, the “Three hundred and twentieth” held the highest level of prestige. It was manufactured from 1937 to 1942 in two series, not including the military SUV Kubelwagen, which was developed based on its platform.
