The first Imperia cars were the work of the German Paul Henze, who himself handled an 8-litre car in the 1907 Kaiserpreis. At first only a Imperia 24/30hp four of 4.9-litres was marketed with low tension magneto and coil-ignition, 4-speed gearbox, and shaft or side-chain drive. The smaller 3-litre Imperia car that followed was shaft-driven, and a 1.767cc monobloc four arrived during 1909. As late as 1911 an immense, Kaiserpreis-inspired chain-driven 9.9-litre 50/60 Imperia car was still offered. In 1912 Imperia cars merged with Springuel, but though the latter name soon vanished, Jules Springuel took over the management, and some Springuel designs were sold under the Imperia car companies name. In 1914 Imperia cars in a range of conventional, well-made small volume fours, of 1.8-litres, 2.6-litres, 3.6-litres and 5-litres was offered.

In 1919 the Imperia car company took over the manufacture of the Spanish Abadal (this had always had a substantial Belgium content), offering both a 3-litre Imperia Type E, and the Hispano-Suiza-like 80x180mm 3.6-litre Imperia Type T, complete with handsome V-radiator as found on subsequent Imperias. These Imperia cars were made in small numbers until 1922, though a 6-litre twin-carburettor sohc Imperia-Abadal straight-9 with Perrot fwb on a 12ft wheelbase never progressed beyond the prototype stage. Equally short-lived Imperia car, was a promosing sports car, the long-stroke 16-valve ohc 4-cylinder 3-litre with which de Tornaco won the 1922 Belgium GP. In 1923 M.A. van Roggen, now in charge at Nessonvaux, came up with his side-valve 1.100cc 6CV Imperia car, a small tourer of Panhard-like appearance, but with an unusual servo-assisted foot transmission brake – brakes on the front wheels were standardized in 1925 on Imperia cars. This Imperia car was quite successful, winning the small-car class of the 1926 Monte Carlo Rally and selling 504 Imperia cars in 1927, but Van Roggen’s ‘empire-building’ did not prosper: plans to produce 6CVs in France (at the Voisin works) and at the British GWL factory proved abortive. The 1928 Imperia car season brought a companion 1.642cc six, later enlarged to 1.8-litres and available in 3-carburettor sporting form, and in this period Imperia cars acquired Excelsior, Nagant (who were converted to making 6-cylinder engines), and the Matthys et Osy coachbuilding works. The slide-valve Imperia car models survived until 1934, acquiring hydraulic brakes at the end, but in 1934 Imperia took out a licence to build fwd Adlers, and until 1940 these were their staple; the 995cc Trumpf-Junior, the 1.645cc Trumpf, and the later Zweiliter were all made. In 1935 the Imperia car company fused with the only other surviving Belgian private-car maker, Minerva, and the big sleeve-valve models from Antwerp disappeared for good.

In 1947 there was a brief revival by Imperia cars with the Imperia TA8, a synthesis of pre-World War 2 fwd models by Adler and Amilcar, powered by the 1.340cc ohv 4-cylinder engine used in 1940 Amilcars. Features of this Imperia car were fravity feed, hydraulic brakes, a 3-speed gearbox with dashboard change, and composite wood and metal coachwork. 

D, 1935

Imperia-Werk AG, Bad Godesberg

The German Imperia factory, well-known for its motorcycles, had already experimented with Imperia cars in 1924/ 1925, but production on a limited scale of Imperia cars was not started until 1935. A 3-cylinder 2-stroke 750cc radial engine mounted in the rear of the Imperia car was used for a streamlined two-seater coupé and for a small monoposto racing Imperia car, both with independent wheel suspension. Financial difficulties stopped production of Imperia cars at an early stage.

DeSoto

US, 1913 – 1916

DeSoto Motro Car Co, Auburn, Ind.

The DeSoto appears to have succeeded the Zimmerman. This was a large car with a 55hp, 6-cylinder engine, which was furnished with a compressed-air starter. The DeSoto model Six-55 five-seater touring car sold for $2185.

US, 1928 – 1960

Chrysler Motors Corp, Detroit, Mich.

The DeSoto was launched in 1928 as a 3.2-litre side valve six to compete with Oldsmobile, Pontiac and the cheaper Nashes. Styling and general design of the DeSoto were in line with the 1929 Chryslers, and at $885 for a DeSoto sedan 90.000 were sold in the first twelve months. A 3.4-litre straight-8 DeSoto on a 9ft 6in wheelbase was announced for 1930 as the world’s cheapest 8-cylinder car. However, DeSoto suffered badly in the Depression, and in 1932, when flexible rubber engine mountings and free wheels were made available, sales dropped to 26.000 DeSoto cars.
The DeSoto disappeared from the British market about this time, though certain ‘Chrysler’ models listed in England (the Mortlake, Croydon, and some of the Richmonds) were in fact DeSoto cars in all but name. A 6-cylinder version of Chrysler’s advanced unitary-construction Airflow, the SE-type with a 4-litre engine, was brought out in 1934, but was an unsuccessful as its bigger sister. Later DeSotos followed regular Chrysler lines closely though in later years there was a tendency for DeSoto to move into a higher price class than Dodge; by 1952 DeSotos started $300 higher than the companion make.
By 1939 the DeSoto cars for sale were being made with independent front suspension, hypoid back axles and column change. There was a choice at DeSoto of two 6-cylinder engines and three wheelbase lengths, the longest of these being reserved for seven-seater bodywork – DeSoto continued to offer a really roomy family car right up to 1954. A 4-speed semi-automatic Vacumatic transmission became an option in 1941, but DeSoto’s big post-war change of models did not take place until 1952, when the division followed Chrysler’s lead in adopting the oversquare ohv V8; the DeSoto version was of 4½-litre capcity and developed 16-bhp. With the advent of Chrysler’s ‘flight sweep’ styling in 1955, the side-valve sixes were dropped and the standard engine in a DeSoto was now a 4.8-litre eight, giving 185bhp in Firedome guise, and 200bhp in Fireflite form. Though this redesigning saved Chrysler sales generally, the slump in the medium-price class had an adverse effect on DeSoto and in 1959 the DeSoto division was merged with Plymouth. Last of the DeSotos were the 1961 models, unitary-construction cars with a choice of three engines: Plymouth’s 145bhp ohv ‘slant six’ as used in the Valiant, and V8s of 230 and 265bhp, the two former only in Canadian DeSotos. Production of DeSoto cars ceased in November 1960 after only a few had been delivered.
