This was a rapid response to the appearance the previous year of a longer version of the Mercedes-Benz Typ 200 which had managed in a very short time to capture practically the entire German taxi business.

A lengthened version of the Opel 2 Liter, with a 3,050 mm (120 in) wheelbase, appeared in August 1934, targeted unapologetically at taxi operators.

It was no coincidence that a rival model was the longer wheelbase version of the Mercedes-Benz Typ 200 which since its appearance in 1933 had achieved impressive sales volumes in Germany primarily because of its popularity with taxi operators.

[3] The 1932 side valve six cylinder engine was a bored out version of the unit used on the car's predecessor with which it shared its 90 mm stroke.

[5] When the car first appeared in January 1934 there the choice was between a four-door Iimousine (saloon) and a two-door, four-seater cabriolet with two side windows.

The least expensive of them, the four-door, six-seater long wheelbase Limousine came with a manufacturer's listed price of 4,800 Marks throughout the model's production period.

1936 saw the withdrawal of several open topped versions of the long wheel base car, and by 1937 only the standard (shorter wheelbase) length models, listed at prices 150 Marks lower than those applied between 1934 and 1936, remained on offer.
