Engineer Arthus de Coninck founded the 'Compagne Nationale Excelsior' in Brussels in 1903. The first cars were built in 1904 and had one, two or four cylinder Aster engines. The models were not that special however. It was only in 1907 that the make really made the headlines with the Adex, powered by a six-cylinder side-valve engine with a capacity in excess of nine litres. In 1912, an Excelsior took second place in the French Grand Prix. And when the Belgian royal family ordered an Excelsior, the advertising value of this proved considerable. The Albert I was the most beautiful, but also the last, Excelsior, In 1929, the make was sold to its competitor, Imperia. Until 1932, the company was called Imperia-Excelsior, but from that year the name Excelsior was dropped from the nameplate.
