Kühlstein

The Kühlstein Wagenbau in Berlin-Charlottenburg was a German coachbuilding company that produced electric cars from 1897 to 1902.

Schulze was also a member of the supervisory board of the newly founded Carburit Gesellschaft mbH, which served to supply fuel to automobiles[4].

With an electric car, Kühlstein was one of only four exhibitors at the first International Motor Show Germany (IAA) in Berlin in 1897.

It was precisely these exhibitors who demonstrated their vehicles in front of the Hotel Bristol (Berlin) on 30 September 1887.

In Berlin, in 1899, a number of taxi carriages were equipped with gasoline "Avant Train" by Kühlstein[6].

The vehicle had a permissible payload of 1.26 t. This allowed the transport of up to 18 people, who could be accommodated in three three levels of seating.

A postcarriol, which had already been rebuilt in 1899 and received gold and silver medallions in 1900 at the Paris Exibition, was not successful for the company.

Electric vehicles continued to fade into the background and around 1900 Joseph Vollmer, Jenny Kühlstein (Ernst Kühlstein's daughter) and Erna von Rahmdohr filed patents for gasoline and alcohol engines.

In October 1900, Jenny Kühlstein married Lieutenant Wilhelm von Rahmdohr of the 2nd Pomeranian Regiment[10].

At the end of 1901 / beginning of 1902, the world's first sulphuric acid transport truck with a petrol engine was built for the chemical company Dr. E. ter Meer & Cie.

The vehicle had a 17 hp two-cylinder engine and had a permissible gross weight of 7 t. The top speed was 13 km/h[11].

The Kühlstein Wagenbau company established itself in aircraft construction and registered the pilot Bollmöller for the long-distance flight Berlin - Vienna in 1912 with its own Court monoplane[14].
