This well-known bicycle and typewriter firm had already built components for Benz as well as a few De Dion tricycles when their first car appeared in 1900. This closely resembled the contemporary Renault, with tubular frame, shaft drive, and front-mounted 400cc single-cylinder De Dion engine; suspension was full-elliptic all round and steering was by tiller, but both these archaisms had gone by 1901 when a bigger 510cc power unit was standardized. By 1902 the company were making their own engines, an 850cc single and a 1.7-litre twin, there were four forward speeds, and the lateral radiators continued the Renault idiom.

With the arrival of Edmund Rumpler in 1903 the Adler idiom crystallized, even if this experimental swing-axle suspension did not pass beyond the prototype stage. Characteristics of the new models were side valves in an L-head, dual ignition, pressed-steel frames, and rectangular radiators. Four cylinders were preferred, though singles were still offered in 1905, and twins as late as 1909. By 1905 there were 4-cylinder cars of 2.8-litres, 4-litres and 7.4-litres, this last figuring in Adler’s Herkomer Trophy entry, and attracting an order from Kaiser Wilhelm II in 1907. If the 1906 Kleinwagen, a 1.032cc aiv V-twin with water cooling and steel artillery wheels, marked a retrograde step, by 1907 the company had adopted the unit gearbox, and were experimenting with ioe engines, achieving a 3rd place in the Prince Henry trials. There were also some modest short-stroke fours. A 2-litre 8/15ps was followed a year later by the successful 1.555cc 7/15. This developed into the 1.8-litre 7/15, popular in England as the 12hp. These small Adlers had dual ignition, but foot accelerators were found only on the bigger cars as late as 1913. There was a fast 5.2-litre 76bhp ioe model for the 1910 Prince Henry Trials, and a smaller 3.2-litre version was offered to the public. It evolved into the 15/40 of 1913, with 3.8-litre and 69bhp, used as the basis for Adler’s unsuccessful 1914 T.T. racers. Their Knight-engined 1911 cars did not progress beyond the prototype stage, but very attractive was that year’s new model, the 1.3-litre K voiturette, initially with pair-cast cylinders, but offered in 1913 with Monobloc engine and a choice of side-by-side or tandem seats. Rear suspension was full-elliptic. It did 50mhp and 38mpg, and was well received by Britons, who bought it under the name of Morgan-Adler Carette. There were also some large sv fours, the 4.8-litre 19/45 appearing in 1911, followed in 1912 by a 7.8-litre 30/70, and in 1914 by a V-radiatored 9.1-litre monster, top of a nine-model range. Also new was an enlarged K, the 1.552cc KL with four-seater bodywork and semi-elliptic rear springs.

A selection of the more popular 1914 types reappeared in 1919, and even in 1922 a replacement for the KL, the 6/22PS, retained a fixed head and reverted to a separate gearbox. Adler’s first sixes came in 1925, these boasting alloy pistons, detachable heads, and front wheel brakes. The 10/50 had a 2.6-litre Monobloc engine, but the 4.7-litre 18/80 was of biblock type. Also new was an essay in the American idiom, Becker’s 1.550cc 4-cylinder Favorit. Three years later it had been joined by a 2.9-litre six and a 3.9-litre straight-8, both with hydraulic brakes, these being offered on an enlarged and modernized Favorit in 1929. 

At the Geneva Show in 1932 Adler presented their new 1.5-litre Trumpf with front-wheel drive and independent wheel suspension, a design of H.G. Röhr. This first front-driven car was followed by the 1-litre Trumpf Junior, the 1.7-litre Trumpf and the 2-litre model. The competition versions of these models – very often fitted with aerodynamic bodies – were very successful in the years from their appearance to the outbreak of World War 2. Streamlined Trumpf and Trumpf Junior cars gained 22 international records in 1935 and 1936 on the Avus and the Darmstadt Autobahn. A win in the Leinster Trophy Race of 1934, a Team Prize at Spa in 1936 in the 2-litre class, a 2-litre class win and 6th place overall at Le Mans in 1937 were only a few of the victories. In 1937 Adler introduced a rear-wheel driven model again, the 2.5-litre with 6-cylinder 50bhp engine, aerodynamic body and swing axles. The sports version of this type developed 80bhp.

Production of private ceased in 1939. Some prototypes of the Trumpf Junior were produced after the war and were on show at the Hanover Fair 1948, but production was not taken up. Instead of this, production of motorcycles was resumed, lasting until 1957.

Morgan

GB, 1905 – 1906

Morgan and Co Ltd, Leighton Buzzard, Beds.

Made by a well-known firm of coachbuilders, the Morgan car was a conventional shaft-driven car with 5.8-litre T-head 4-cylinder Mutel engine, distinguished only by the Sparks-Boothby hydraulic clutch on the Morgan car, soon abandoned in favour of an ordinary leather cone. Only about five Morgan cars were made and their lack of success resulted in Morgan cars becoming Adler concessionaires in 1907, and abandoning motor manufacture.

GB, 1910 to date

Morgan Motor Co Ltd, Malvern Link, Worcs.

This Morgan car was the best-known, and best, of the British 3-wheelers that were popular while the horsepower tax gave the Morgan cars an advantage. H.F.S. Morgan’s tricycle was also the first of its type, this Morgan car going into production in 1910. At the front of a tubular chassis frame was an sv, air-cooled V-twin motor-cycle engine of 1.100cc by JAP, transversely mounted. Transmission of the Morgan car was by dog clutches and chains, providing two forward speeds. The steering was direct. The front wheels of the Morgan car, had independent front suspension, by sliding pillars and coil springs. There were two seats. A reasonable amount of power plus light weight meant an excellent performance of the Morgan cars. The Morgan car was safer than most 3-wheelers because its road-holding was above average. This recipe made the Morgan car popular with sportsmen, for whom the Morgan Grand Prix model was produced in 1914: the first catalogued competition Morgan car. Soon afterwards, an exiguous four-seater Morgan car, the forerunner of the Morgan Family model of the 1920s, was listed.

After World War 1, Morgan carscontinued to cater for all markets. Names changed, but the Morgan Sports or Morgan Standard model was the normal two-seater, also available in De Luxe form; the Morgan Family model was the more capacious type Morgan car, and the long-tailed Morgan Aero, later the Morgan Super Sports, was the Morgan car intended for serious speed work. Engines of Morgan cars were water- or air-cooled to choice, most being supplied by JAP, or by Blackburne in the case of the competition Morgan cars. From 1925 all the latter’s power units had overhead valves. By 1927 the Super Sports Morgan car could attain 80mph in standard trim, while the less sporting Morgan cars now had internal expanding front wheel brakes and electric starting. Geared-down steering and (if required) three forward speeds followed on Morgan cars in 1929. Even so, Morgan cars were losing customers to new, cheap sports cars such as the M-type MG. Three speeds and reverse in a normal gearbox (though still with chain final drive) were available from 1931 and standard on the Morgan car after 1932, and a modified 8hp Ford 4-cylinder engine could later be had in the Morgan car instead of the twin. Four years later the first 4-wheeled Morgan car was introduced, the excellent little Morgan 4/4. This Morgan car used an 1.122cc 4-cylinder Coventry-Climax engine with overhead inlet valves, developing 34bhp. The Morgan car was still light in weight, and retained the Morgan independent front suspension, so the performance and handling qualities of Morgan cars were well up to form. The Morgan car could attain 75mph. The twins were last catalogued in 1939.

Just before World War 2, a 1.267cc Standard 10hp engine with ohv head was substituted in the Morgan 4/4. When this was no longer available, from 1950, Morgan fitted a tuned Standard Vanguard unit in the Morgan car giving 70bhp. In this Morgan Plus Four, as the Morgan car was renamed, performance became still more lively, and when the 90bhp Triumph TR2 engine became available in 1954, maximum speed of the Morgan car rose to 100mph for the first time. With the advent of the Morgan Plus Four, there was no longer a small Morgan car, but this gap was made good in 1955, when the Morgan Series 2 4/4 arrived. This Morgan car used the very hard-wearing 1.172cc sv Ford Ten engine which had powered F4 Morgan. (The latter was the last 3-wheeler Morgan car, which had been made until 1950.) The result was a cheap, pleasant and reliable sports Morgan car of the old school. Later, the ohv Ford 105E engine was substituted. The latest version Morgan car had a 1.599cc 98bhp engine, a 4-speed all-synchromesh gearbox, front disc brakes, and the traditional Morgan suspension. The Morgan Plus Four kept pace with Triumph’s TR engine development, also acquiring disc brakes and, eventually, the 2.138cc 105bhp TR4 unit. A streamlined coupé, the Morgan Plus Four Plus of 1964, was a brief deviation from the classical Morgan car line which met with little approval and was discontinued after only 50 of these Morgan cars had been sold. When Triumph changed to a six during 1968, Morgan cars adopted a new engine for their bigger Morgan cars, and the Morgan Plus Four became the Morgan Plus Eight, powered by Rover’s 3 ½-litre 160bhp V8 and capable of 125mph. The 1973 versions of the Morgan car use the 4-speed all-synchromesh Rover gearbox in place of the Moss box previously fitted.
