History
Impéria was a Belgian automobile manufacturer from 1906 until 1948. Products of the Ateliers Piedboeuf of Liège, the first cars were designed by German, Paul Henze. These were four-cylinders of 3, 4.9, and 9.9 litres. The next year, the company moved to Nessonvaux, Trooz municipality, and began production in the old Pieper factory. Impéria produced a monobloc 12 hp in 1909. In 1910, the company merged with Springuel.
The Nessonvaux factory began producing Abadals under license as Impéria-Abadals from about 1916. In 1921, it built three ohc 5.6-litre straight-eights. These were quickly replaced by an ephemeral ohc 3-litre 32-valve four-cylinder which had a top speed of 90 mi/h. This was followed by an 1100 cc slide-valve 11/22 hp four designed by Couchard, one of the first cars ever built with a sunroof. Its engine rotated counterclockwise, and its transmission brake also served as a servo for those on the front wheels. In 1927, a six-cylinder of 1624 cc appeared; this had been available in three-carburettor Super Sports form from 1930.
