Industrial Production
Cologne and The Rhineland are industrial heavyweights
Traditionally, Cologne is one of Germany's strongholds for industrial production. The automobile pioneer Nicolaus Otto invented the four-stroke engine in Cologne in the 1860s and in 1901, one of the world's first mass-produced cars rolled off the production line at Audi founder August Horch's factory in Cologne-Ehrenfeld.
More than 9,600 companies make up Cologne's manufacturing sector. The city's leading market also includes skilled trades and construction, as well as other companies involved in the processing of goods. Together they employ approximately 113,000 people and generate a turnover of 58 billion Euros each year. Nineteen percent of all employees in Cologne are engaged in some form of manufacturing, fabrication or skilled manual labour. The sector generates 29 percent of sales in Cologne's overall economy, which makes it the city's most important market in economic terms.
