From its beginning, the name of Alvis has connoted high quality, long life and better-than-average performance. The first production Alvis set the trend. Those responsible for it were T.G. John, formerly of Siddeley-Deasy, and G.P.H. de Freville, who had worked for D.F.P. and had designed aluminium pistons bearing the name of Alvis for them. Their 10/30hp light car, current until 1922, used an extremely efficient 4-cylinder sv engine of 1.460cc made by Alvis, a 4-speed gearbox and attractive aluminium bodies by Morgan or Charlesworth. It was available in two-seater, four-seater or Super Sports form. The last-named as the first Alvis to have the famous ‘duck’s back’ body. Though noisy and expensive, the aLVIS ‘10/30’ was immensely popular among sporting motorists. In 1921, 322 examples were sold and by the following year the Alvis company employed 350 people. At the end of 1919, the new-born company had undertaken to deliver 1.000 cars, but the moulders’ strike which a brief spell during this period, the company made the Buckingham cyclecar.

In 1922, an engine of 1.598cc with a bigger bore and rated at 12/40hp was introduced in Alvis cars designed more for touring. Captain G.T. Smith-Clarke became chief engineer in 1923. He was responsible for the push-rod ohv 12/50hp engine, which was quieter and more powerful than its predecessors and at the same time extremely strong and long-lasting. It was first seen, in modified form, in the Alvis that won the Brooklands 200-Mile Race of 1923. The touring Alvis models were provided with 1.598cc engines, but the Alvis Super Sports had a shorter stroke giving 1.496cc and was more highly-tuned. The former were usually capable of about 60-65mph, but the latter would exceed 70mph comfortably. Handling qualities of all Alvis models were excellent, while bodies were by Cross & Ellis. During 1924 all Alvis cars went over to the new engine. At first, the Alvis firm’s survival was doubtful. Although 963 units of the older Alvis models had been sold in 1923, a receiver had to be appointed in the following year, because of lack of the capital needed for production on a scale to meet demand. More money was forthcoming, however, and the new Alvis 12/50hp restored the company’s fortunes. Prices were reduced for 1926, and all Alvis models were given front-wheel brakes. The chassis was stiffened by doing away with the separate subframe that had carried the engine and gearbox, and the engine was rubber-mounted. The downward-sloping ‘beetle-back’ tail was now the Super Sports style. By 1928, 6000 Alvises were on the road, and production was running at about 900 chassis per annum.

In that year, Alvis introduced a new type that was also to be a great success. Following fashion, it was a small six of 1.870cc. Similar in design to the old four, this Alvis was smoother, more flexible and quieter. Bodies were roomier and gearing was lower. This Alvis 14.75hp was superseded by the Alvis Silver Eagle in 1929, a car with a bigger bore that gave a mistake. They put into production a Alvis sports machine that had front-wheel-drive (Alvis FWD) – the first instance of this type of drive in a catalogued car – and independent suspension by four quarter-elliptic springs at the front and swing axles with quarter-elliptics at the rear. The 4-cylinder, 1.482cc, single ohc engine utilized many Alvis 12/50 parts, and could be had with a Roots-type supercharger. Helped by a low centre of gravity, the roadholding was very fine, and so were the brakes. During 1928 this Alvis model finished 6th and 9th at Le Mans, and 2nd in the Ulster Tourist Trophy race. In the following year an 8-cylinder version, still of 1½-litres was added. Unfortunately, the Alvis fwd had a very specialized, limited appeal, being complicated, unconventional, temperamental and hard to work on. However, Alvis were so confident in them and in the new six that they announced suspension of the production of the Alvis 12/50 in 1929. It was hurriedly reinstated when the six, popular though it was, proved insufficient to keep the Alvis company going alone. It was for sale until 1932, alongside a new sporting variant, the Alvis 12/60hp.

This was the Alvis company’s last out and out sports car, but its reputation for high-performance vehicles was sustained by the introduction of another new line for sale in 1932. The Alvis Speed Twenty was an exceptionally low-built, handsome fast tourer of modern appearance that combined the refinement of a medium-sized (2.511cc) six with speed, excellent roadholding and brakes, stamina and a reasonable sales-price. The car, and the types which succeeded it were a great success. The engine was a slightly tuned version of the largest option available in the Alvis Silver Eagle, and the chassis, too, was basically similar to that of the earlier Alvis model, which was retained. The power output was about 87bhp, permitting the better examples of the Vanden Plas open tourer to attain 90mph, in spite of the car’s weight, which was an equally traditional Alvis feature. The bodies were all coachbuilt.

With the introduction of this Alvis, the character of Alvis policy in the 1930s was set: the Alvis Speed Twenty and its developments provided the glamour, while an assortment of ‘bread-and-butter’ fours and sixes backed it up. All had push-rod ohv engines. The old Alvis ‘12/50’ and Alvis ‘12/60’ were replaced for 1933 by the sale of the heavier Alvis Firefly in the 1½-litre, 4-cylinder range. Much of the extra weight was added by the optional Wilson pre-selector gearbox, which could also be had on its development, the Alvis Firebird of 1935. This car, however, had an 1.842cc engine, in an attempt to cope with the avoirdupois. The Alvis Silver Eagle was joined early in 1933 by the 2.511cc Alvis Crested Eagle, which also had a Wilson gearbox. This was a chassis intended to carry heavier boddies, and was important because it was the first Alvis touring car to have independent front suspension, which was by a single transverse leaf. This feature, together with an all-synchromesh gearbox, was seen on the 1934 Alvis Speed Twenty. The latter model for sale, which was also growing heavier with increasing public demand for comfort rather than sporting pretensions, was given a bigger engine of 2.762cc in 1935 by lengthening the stroke.

For the same reason, the Alvis 3½-litre also made its bow. It was basically similar to the Alvis Speed Twenty, which it supplemented, but had a smoother, quieter engine with a bigger bore, providing 3.571cc and was designed to accommodate more comfortable, less sporting bodies. The Alvis 3½-litre was, however, a more powerful car than the Alvis Speed Twenty, with 110bhp. It was a short and logical step to replace the Alvis Speed Twenty with a new car for sale for 1936 that combined the virtues of both models. This was the fine Alvis Speed Twenty-five, which used the 3.571cc engine. Capable of a smooth and silent 95mph in saloon form, it was what many people still regard as the best Alvis ever built. At the same time, a car that was originally envisaged as a replacement for the short-lived Alvis 3½-litre was announced. This Alvis 4.3-litre had the same engine, bored out to a capacity of 4.387cc and providing 123bhp. With the introduction of the short-chassis sports tourer version for 1938, the Alvis 4.3-litre became the most exciting Alvis in the range, for it could easily exceed 100mph, with acceleration to match. Some consider that it was not quite as good-looking as the Alvis Speed Twenty-five, nor equally refined.

A new four for sale to replace the Alvis Firebird was listed for 1938. This was the Alvis 12/70hp, a George Lanchester design, with an 80mph performance in spite of its weight. The engine size was unaltered. The Alvis Silver Eagle had been dropped in 1936, but the Alvis Crested Eagle became for sale in a number of versions with the 2.762cc and 3.571cc engines as they appeared, in less highly-tuned forms. The Alvis Silver Crest, another Alvis car in which George Lanchester had a hand, was also brought in for sale in 1938 alongside the 12/70hp. It was intented to carry bodies of the more formal sort, and was powered by the 2.762cc engine, among others. It, too, had independent front suspension.

An aero engine works had been opened as early as 1937. The Alvis car factory at Holyhead Road, Coventry was completely destroyed by bombing in 1940, but the company continued to make aero engines – Rolls-Royce Merlins – at eighteen shadow factories. After World War 2, Alvis made their own Leonides unit and Alvis car production was restarted in 1946. A one-model policy, tailored to meet conditions of austerity, was adopted. Quality was still the main characteristic of the new Alvis TA14 for sale, which, in Alvis tradition, used a 4-cylinder push-rod ohv engine, now of 1.892cc.This Alvis TA14 car was the direct descendant of the 12/70hp. An ugly sporting model appeared briefly for sale in 1948. The Alvis TA14 was dropped during 1950 and the Alvis TA21, a big six, substituted. This was the first entirely new post-war Alvis. Its 2.993cc engine developed 90bhp, and this Alvis car – though not its sports roadster variant the Alvis TB21 – was as slower car than the Alvis Speed Twenty-five. Not so its development, the Alvis TC21/100, for sale in 1954 and 1955. This, after attention from Alec Issigonis, had a tuned engine providing 100bhp and a higher axle ratio, and carried a 100mph guarantee. The Alvis TC21/100 did not last long, for in 1955 there appeared one of the handsomest cars Alvis ever made, the Graber-designed Alvis saloon on what was virtually the Alvis TC21/100 chassis. Few were built until 1959, when this car was given a modified engine delivering 120bhp and renamed the Alvis TD21. It acquired disc brakes as standard fittings on all four wheels for 1962. For 1964, it was replaced by Alvis TE21, with 130bhp and five forward speeds. Automatic transmission was optional. In 1965 Rover acquired a controlling interest in the firm; production of private ceased in the summer of 1967.

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.
