1907 - 1911
Before entering the car business the firm of Houwing & Co. manufactured boats and marine-engines at the Omnia Engineering Works in Rotterdam. In 1906 they planned to build cars under licence from an unknown Belgian car factory, and displayed a number of chassis at the R.I.A. show. The smallest one had a 10/12hp 2 cylinder engine and a 3-speed gearbox. A 12/15hp 3-cylinder engine was available. A third model was a 4-cylinder 16/20hp with thermosyphon cooling. The heaviest chassis had a 45/55hp 4-cylinder engine with a displacement of 8012cc. Most of the cars were ordered by the H.A.T.O. taxicab organisation at The Hague, who preferred the Landaulet body style.
In 1909 the management took the decision to standardise the production on one type of chassis, using the 15/20hp 4-cylinder monobloc with a bore and stroke of 85 x 110mm and Bosch magneto ignition. It seemed that this chassis was a licence-built Spyker, and it had been claimed that Omnia was finally only an assembly plant, with frames delivered by the French firm Dyle et Bacalan. After building about 100 cars, Omnia closed its doors in 1911.
