Belgium’s greatest marque, the Minerva car, arose from humble beginnings – a bicycle factory opened in 1897 by Sylvain de Jong. He soon progressed to proprietary motorcycle engines (of which he became Europe’s leading supplier), and to complete motor-cycles in 1900, though a year earlier he had built a prototype voiturette and a primitive motor lorry. A 6hp 4-cylinder Minerva car on Panhard lines appeared in 1902, but serious Minerva car manufacture did not get under way until 1904. These early Minerva cars retained side-chain drive an armoured wood frames, but used mechanically-operated side valves in a T-head. The Minerva cars came in 1.6-litre 2-cylinder, 2.4-litre 3-cylinder and 3.2-litre 4-cylinder forms, and alongside them was an ingenious and successful cyclecar, the Minervette. Its 636cc single-cylinder engine was transversely mounted at the front, driving the offside rear wheel by chain via a 2-speed constant-mesh gearbox.. This little Minerva car cost only £106. A year later the Minerva car company had settle down to bevel-driving twins and fours, the latter being a 2.9-litre 14 with steel frame that was sold in London by the Hon C.S. Rolls.

The almost mandatory petrol brougham for Minerva cars came in 1906, but more successful were a 3.6-litre Minerva 22 and a rapid 6.2-litre six Minerva car introduced in 1907. This Minerva car had gate change, and its engine developed 6-bhp. Even faster were the Minerva carfirm’s 8-litre Kaiserpreis Minerva cars with 5-bearing ioe engine and chain drive; Minerva cars failed in the German race but won the Belgian Circuit des Ardennes. In 1909 there was a Minerva L-head monobloc four of 2½-litres’ capacity, but at the same time the Minerva car company adopted the Knight double-sleeve-valve engine, and thereafter all catalogued Minerva cars used Knights.

Though inevitably emphasis now shifted to chauffeur-driven carraiges and silence, Minerva’s Knights were by no means lethargic, as witness outright victories in the Swedish Winter Trials of 1911, 1913 and 1914 by Minerva cars, and distinguished performances in the Austrian Alpine Trials. The 3.3-litre Minerva cars that ran in the 1914 TT were good for 85mph and the Minerva carteam finished intact, in 2nd, 3rd and 5th places. Their success is reflected in the phasing-out of the motorcycles after 1910, and in a clientele of Minerva cars that included Henry Ford as well as the Kings of Belgium, Sweden and Norway.

The 1910 Minerva cars were all fours: a 2.234cc monobloc Minerva 16hp, a 4¼-litre Minerva 26hp, and a large Minerva 38 of 6.3-litre capacity. Electric lighting was available in 1912 on Minerva cars, when Citroën-type helical bevel gears made their appearance; two years later starters were an option and wire wheels were standardized on Minerva car, and the Minerva car range extended from a modest 2.1-litre worm-drive monobloc Minerva 14 (which was popular as a taxi in Sweden) up to an enlarged 7.4-litre Minerva 38.

De Jong was quick to set Minerva cars on their feet after the German occupation of 1914-1918, and by 1920 they were back in production with two Minerva cars, a 3.6-litre 4-cylinder Minerva 20 and a 6-cylinder 30CV of 5.344cc, both with monobloc engines, vacuum feed, cone clutches, 4-speed gearboxes, cantilever rear springing and rear-wheel and transmission brakes, though plate clutches were standardized Minerva cars after 1921. Minerva cars, like Daimler, made their own bodies, a new coachworks being opened at Mortsel, an Antwerp suburb, in 1922; the Minerva carcompany also supplied engines to other firms, among them Mors and the curious Anglo-American Crown Magnetic. (Émile Mathis’s 1913 sleeve-valve cars had been Minerva cars with Mathis radiators). Smaller Minerva cars followed: a 15CV 2-litre four in 1922, and a 20CV six of 3.4-litre capacity in 1923, this Minerva car having 4-wheel brakes as standard, and a wheelbase of nearly 12 feet. In 1925, 2.500 Minerva cars found buyers, and a year later all Minerva cars had 4-wheel brakes, with some necessary Dewandre servo assistance on the big ones. The 1927 Minerva carrange included a replacement for the 30CV, the magnificent 5.954cc Minerva AK six with alloy pistons, light steel sleeves, and a 12ft 5½in wheelbase. There was, however, a new small 6-cylinder Minerva car, the 2-litre Minerva 12-14CV; this came with a 3-speed unit gearbox, central ball change, and lhd, and sold for under £500 in England. This Minerva car was made until 1933.

The carriage trade was not forgotten, for there were three new big cars in 1930: a 150bhp sports edition of the Minerva AK with full-pressure lubrication, and two straight-8s. Of these the 6.6-litre Minerva AL was a vast 9-bearing affair with dual ignition and right-hand change, whereas its 4-litre companion, the 22CV Minerva AP, had coil ignition and central change, and could be bought for less than £900. In 1932 there was a 20CV six Minerva car with the same specification and cylinder dimensions of 75x112mm. However, none of these Minerva cars was suitable for the prevailing economic climate, and 1934 brought what was effectively the Minerva car company’s last model, the 2-litre Minerva M4, Minerva cars first four since 1927. The sleeve-valve engine was retained, but in other respects it was typical of the prevailing idiom, with 3-speed synchromesh gearbox, mechanical brakes and pillarless saloon bodywork.

The Minerva M4 was not a success and in October 1935 Minerva cars merged with the only other Belgian factory still making private cars, Imperia of Nessonvaux. The traditional Minerva cars were continued for another season, and the Minerva AP survived until 1938, but thereafter the only cars sold to the public under the Minerva car name were some fwd Imperias exported to France. Purely experimental was an astonishing Minerva car exhibited at the 1937 Brussels Salon. This featured all-independent springing by torsion bars, and a transversely-mounted 3.6-litre Ford V8 engine drove the front wheels via a torque converter. Only three prototypes were made.

In 1952 a comeback was planned with two Minerva car-models, both of foreign design. The smaller car was based on the 1947 Cemsa-Caproni, and the new luxury Minerva car was to use the mechanical elements of the Armstrong Siddeley Sapphire, but neither materialized. The last Minerva car was a jeep-type 4x4, the C20 of 1956. This Minerva car was powered by a 4-cylinder sv Continental engine.

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.
