This make succeeded the Weller and was a John Weller design developed from a commercial 3-wheeler, the AutoCarrier (hence the initials) with a single-cylinder rear-mounted moiv engine, 2-speed epicyclic gear and tiller steering. These side-by-side two-seater A.C. Sociables were made up to World War 1 and sold for less than £100, but in 1913 the company brought out a 10hp 4-cylinder light car with a 3-speed gearbox in the rear axle; the engine was a 1.100cc Fivet. A modernized version with electrics and a disc transmission brake appeared with the 1½-litre side valve Anzani engine in 1919, the giving way to A.C.’s own power unit in 1925 – the fours were dropped at the end of 1928. Also at the 1919 London show was Weller’s famous 1.991cc single ohc wet-liner six, an advanced power unit for its day. It did not get into production unitl 1922, but it remained in the catalogue until 1963, by which time output had gone up from around 35bhp to 103bhp. Under the aegis of S.F. Edge, the company’s director from 1921 to 1929, A.C.’s were raced, through their main interest was long-distance record work. A 4-cylinder car took 57 records at Brooklands Track in 1921; J.A. Joyce’s 16-valve ohc 1500cc single-seater covered 100 miles in the hour from a standing start in 1922; and Gillet broke the World’s 24-hour Record at Monthlhéry in 1925 on a 2-litre six. The 6-cylinder car of the Hon. Victore Bruce and W.J. Brunell became the first British entry to win the Monte Carlo Rally in 1926. In 1925 4-cylinder cars sold from £300, the cheapest six being £90 dearer, 4-wheel brakes were an optional extra, being standard on the 2-litre by 1927. All these cars retained the rear-axle gearbox, though the disc transmission brake did not last long.

Financial difficulties supervened in 1929, and virtually no cars were made for a couple of seasons, though the 1930 Magna series boasted hydraulic brakes. Th Hurlock brothers bought the company in 1930, and the 2-litre emerges in 1933 as a sporting machine with mechanical brakes and a conventionally-mounted 4-speed gearbox, in 56bhp and 66bhp versions. These cars were made on a bespoke basis, prices starting at around £435. Pre-selector boxes were available from 1934 and standard 1935 versions had synchromesh, while cars sold in 1936 had engines of 60 and 70bhp with an 80bhp sports engine available in a special short-chassis two-seater model. A 90bhp super-charged engine was listed in 1939.

A.C. resumed car production in 1947 with a saloon in the modern idiom. This had a 74bhp engine, and hydro-mechanical (full hydraulic from 1950) brakes, but retained its semi-elliptical springing up to the end of production in 1957. Some 3-wheeled monocars for invalids were made with 250cc B.S.A. motor cycle engines, and in 1953 came the Petite, a 3-wheeler roll-top convertible with rear-mounted 350cc Villiers power unit; despite a price of under £400, this never really became popular and was dropped in 1958. 1954 saw the advent of the Ace sports two-seater, a tubular-framed machine with all-independent suspension designed by John Tojeiro. With an 85bhp A.C. engine it could top the 199mph mark, and was later made also with 2-litre and 2.2-litre Bristol and 2.6-litre Dagenham Ford engines. Front disc brakes were standardized in 1960. In 1963 this car was developed into the Cobra (inspired by the American Carroll Shelby) with disc brakes all round and a 4.7-litre oversquare American Ford V8 engine developing 330bhp.

A Cobra finished 4th at Le Mans in 1964, but between 1965 and 1968 Shelby American Inc were responsible for the marketing of the 7-litre type, all Cobra production being abandoned in the latter year. From 1966, however, A.C. offered a luxury convertible or hardtop with Frua bodywork and a 7-litre Ford V8 engine, available with a 4-speed manual or an automatic gearbox. This 428 series was continued into 1973 at a price of £7.010. A.C. also made a special single-seater 3-wheeler for invalids with single-gear automatic transmission, wheel or handlebar steering, and fiberglass coupé body, powered by a 500cc 4-stroke twin engine.

Lea-Francis

GB, 1904 – 1906; 1920 – 1935; 1937 – 1953; 1960

(1) Lea & Francis Ltd, Coventry, Warwickshire, 1904 – 1935

(2) Lea-Francis Cars Ltd, Coventry, Warwickshire, 1937 – 1960

Lea Francis started as bicycle manufacturers, like so many car makers, but unlike most of the rest, never went over permanently and consistently to Lea Francis cars. These Lea Francis cars appeared in fits and starts. The first appeared in 1904, in the shape of a 15hp Lea Francis car with a 3-cylinder horizontal engine, the oddest feature of which was its connecting rods over 3ft long. In the same year, however, Lea Francis stopped making their cars, and Singer the Cycle Company began building Lea Francis cars under licence and under the Singer name. R.H. Lea had in fact worked for Singer before branching out on his own. Thus began another famous car name. Lea Francis made motor cycles from 1911, and they concentrated on these until 1920. In that year two Lea Francis cars reappeared beside the motorcycles; assembled 4-cylinder touring Lea Francis cars of 11.9 and 13.9hp. Few of either were made. Then, late in 1922, the Lea Francis car company found its feet at last, with an equally conventional assembled light Lea Francis car. This Lea Francis car had a 1.074cc 4-cylinder sv engine of 8.9hp by Coventry-Simplex, replaced in the following year by a 10hp Meadows unit of 1¼ litres with overhead valves. A Lea Francis car with 7hp Bradshaw flat-twin engine came to nothing. There were 3 forward speeds and quarter-elliptic springs at both ends. The 10hp Lea Francis car was very popular, and was made until 1928. Like other Lea Francise cars to come, it was well made, dependable, and lively. The great moment came for the Lea Francis cars in the very important RAC Small Car Trials of 1924, in which the Lea Francis car made the best all-round performance. During 1925 a wider family market was sought with the 12/22hp J-type Lea Francis car. This Lea Francis car had a longer wheelbase, allowing more spacious bodies, front-wheel brakes, a 1½-litre 4EC Meadows engine to cope with the weight and a 4-speed gearbox. For the sake of comfort, semi-elliptic springs were substituted at the rear on the P-type Lea Francis car introduced for 1928, which also had a plate clutch and 4ED meadows engine.

The Lea Francis car firm’s first serious sports car was the L-type with 4ED engine, announced for 1925. The Lea Francis 12/40hp was one of the best assembled cars in Britain, and appealed more widely than the light Lea Francis cars. It was, indeed, current until the second cessation of car production in 1935. However, Lea Francis also made some more ponderous, less lively Lea Francis cars, without the same degree of success. From 1925 until 1929, the Lea Francis range duplicated some of the heavy 6-cylinder machines offered by Vulcan of Southport, with whom Lea Francis cars had been associated since 1922. The 18hp Lea Francis car was a 2¼-litre car with cantilever rear springs and overhead worm drive. This Lea Francis car was succeeded by A.O. Lord’s Type T, with its advanced but unreliable Lea Francis LFS-type, double ohc engine of 1.7-litres. There was also, in 1928, a 2-litre six Lea Francis car. These Vulcan/ Lea Francis cars ended with the demise of the Vulcan. However, an excellent Lea Francis car with a six was at last introduced for 1931: the Lea Francis Ace of Spades model, with their own 2-litre, single ohc engine. This Lea Francis car continued alongside the old 12/40hp until 1935, together with a new 18hp Lea Francis car, which was a 2¼-litre enlargement of the Lea Francis Ace of Spades. However, a really powerful Lea Francis car was also listed from 1928. This Lea Francis Hyper Sports was a quite different car, with its heavily-modified, Cozette-supercharged Meadows 1½-litre engine, low build and raked radiator. The sports-racing two-seater Lea Francis car could attain 90mph, though a coupé and a short open tourer could also be had by those who did not intend to enter competitions. The Lea Francis Hyper Sports won the 1928 Ulster Trophy race.

A new company introduced two entirely new Lea Francis cars for 1938. These Lea Francis cars were designed by Hugh Rose, who had been responsible for the Riley Nine engine and, like the Riley, had 4-cylinder power units with push-rod overhead valves operated by two high camshafts. The Lea Francis car had ceased to be an entirely assembled car. A 12hp and a 14hp Lea Francis car were available, with cubic capacities of 1½ and 1.6-litres. Both had a 4-speed synchromesh gearbox. A sports version of the 1½-litre Lea Francis car was also sold, thus maintaining the old tradition. These two ‘Leafs’ were good cars, and as they were new, up-to-date Lea Francis carmodels, they could be continued after World War 2. Most of those built in this period were Lea Francis Fourteens, which were heavier but had a bigger bore and a capacity of 1.8-litres. A tuned sports Lea Francis car of the 14hp arrived for 1948. At the end of that year, an export version of the 14hp Lea Francis car, with torsion-bar independent front suspension, was shown and this suspension was adopted for both the 14hp and for the new 18hp, with a 2½-litre engine, in 1950. The sports model of the 18hp Lea Francis car was a fine car, with 100bhp available. The Lea Francis cars for 1953 had hydraulic brakes, but that was the last year in which the Lea Francis car appeared as a competitive production car. By mid-1952, output had fallen to six Lea Francis cars a week. An expensive car of specialist appeal,  the post-war years were too hard for it. In 1960 a few prototypes of a new sports Lea Francis car, the Leaf-Lynx, were made, but it never reached production. The power unit of this Lea Francis car was a 2½-litre Ford Zephyr, there was independent front suspension and disc brakes were supplied, but the car was ill-favoured and ill received. No better luck attented the Lea Francis carfirm’s attempt to make the Nobel bubble-car.
