The Enduring Legacy of London's Iconic Cabs

London's black cabs are more than just a mode of transport; they are a symbol of the city itself, instantly recognisable and steeped in a rich history of innovation and adaptability. From their humble beginnings at the turn of the 20th century to the modern workhorses navigating the capital's bustling streets, the evolution of the London taxi is a captivating journey of engineering, design, and public service. While pinpointing a single 'most popular' cab in London in 1914 is not explicitly documented in historical records as a quantifiable statistic, the era saw a burgeoning mix of motor cabs vying for dominance, laying the groundwork for the iconic vehicles that would follow.

The early 20th century, particularly leading up to the First World War, was a period of rapid transition from horse-drawn hackney carriages to motorised taxis. This was a time of experimentation, with various manufacturers introducing their designs to meet the growing demand for efficient urban transport. The landscape was diverse, featuring both British and French manufacturers, each contributing to the unique character of London's burgeoning taxi fleet.

The Dawn of the Motor Cab: Pioneers and Early Contenders

The very first motorised cabs to grace London's streets were not the petrol-powered vehicles we associate with the black cab today, but rather electric ones. In a bold move between September 1897 and December 1898, the London Electrical Cab Company introduced 70 Bersey electric storage battery cabs. Nicknamed "Hummingbirds" due to their quiet operation, these cabs, built by the Great Horseless Carriage Company, were powered by 3.5 horsepower motors and had a limited range of 30 miles with a top speed of 9 mph. Despite an improved version later constructed by the Gloucester Railway Waggon Company, their operation proved unprofitable due to frequent breakdowns and the high cost of batteries and tyres, leading to the company's closure in 1899. A single Bersey cab remains preserved today, a testament to this pioneering, albeit short-lived, era.

The title of the first motor cab licensed to operate in London, however, goes to the French-built Prunel in 1903. Operated by the Express Motor Service Company, this vehicle featured a two-seat Hansom body, a 12hp Aster engine, and chain drive, marking a significant step towards the petrol-driven future.

By 1907, Britain was experiencing a taxicab boom, and petrol-engine vehicles began to dominate. French manufacturers played a pivotal role in this early phase. The General Motor Cab Company of Brixton famously purchased 500 two-cylinder Renault cabs that year. Though somewhat underpowered with their 8-9hp engines, these Renaults were a common sight until they began to be replaced by another French import: the Unic. The Unic proved to be an exceptionally popular choice with London operators, maintaining its presence for an impressive 25 years, from 1907 to 1932. Initially powered by two-cylinder engines, post-war Unics adopted four-cylinder units, but their fundamental design remained largely consistent with their Edwardian predecessors. Their widespread adoption speaks volumes about their reliability and suitability for London's demanding conditions, making them a strong contender for a prominent cab in the 1914 era.

British manufacturers were quick to respond to this growing market. Napier, a well-known name in British engineering, produced a taxi from 1908 to 1911 that substantially exceeded their car production, highlighting its commercial success. These Napier cabs featured L-head engines and were offered in both 1.3-litre two-cylinder and 2.7-litre 15 HP four-cylinder forms, with the latter being extensively exported. Humber also entered the fray in 1907 with an Argyll-like cab-over design, later offering conventional designs. By 1910, Humber, Ltd. operated a fleet of 40 Humber cabs in London, indicating their significant, though perhaps not dominant, presence.

Austin, a name that would become synonymous with London taxis, introduced its first cab in 1906, though it initially failed to gain approval. A revised version with the driver seated beside the engine was accepted in 1907, with ten of these operated by the Taxi DeLuxe Company of Kensington. A more conventional 15hp cab followed in 1908. Other manufacturers like Argyll (with a unique cab-over design introduced in 1906, replaced by a conventional one in 1908) and Brasier (marketed as a cab from 1908 to 1913) also contributed to the diverse fleet before the Great War.

Therefore, while no single cab is explicitly named as the "most popular" in 1914 in the provided data, the Unic emerged as a particularly enduring and widely adopted model during that period and beyond, alongside notable contributions from Napier and Humber.

The Inter-War Years: Specialisation and Durability

The period between the two World Wars saw further refinement and specialisation in London's taxi fleet. New manufacturers emerged, and existing ones continued to innovate, driven by the need for more robust, efficient, and comfortable vehicles.

Beardmore, a Scottish steel and shipbuilding conglomerate, made a significant mark with its taxicabs. The Mark I, produced from 1919 to 1923, was famously known as the "Rolls-Royce of cabs" due to its quality and design, fitted with Beardmore's own 15.6 HP engine. This was followed by the Mark II Super (ending production in 1926) and the groundbreaking Mark III Hyper, introduced in 1926 and produced until 1932. The Hyper was notable for being the first cab with four-wheel braking and was significantly smaller and lighter than its predecessors, earning it the nickname "Farthing Cab" for its perceived quickness and manoeuvrability. Production later moved to London, leading to models like the Mark IV Paramount (1934) and Mark V Paramount Ace (1935), which featured advancements like synchromesh gearboxes.

Morris Commercial, part of Lord Nuffield's organisation, also produced a line of taxicabs in the late 1920s and 1930s. Their Type G "International" (from 1929) and the smaller G2 "Junior" (1931) were based on their Oxford car engines. The G2S (1932) and G2SW (1937) featured six-cylinder engines, making Morris the only London cab maker to fit such powerplants, and earning a reputation as a well-built cab popular with owner-drivers.

Unique designs also emerged, such as the Cape Cabs (1929-1936), designed in South Africa, which featured a distinctive transverse sliding passenger door. Over 100 of these were built, some using Austin running gear. Even earlier, Citroen supplied mechanical components for taxicabs built by the London General Cab Company from 1929, and some Austins from 1933 were fitted with repurposed bodies from retired London General's Citroen 11/4 cabs, known colloquially as "Chinese Taxis."

The Iconic Era: Austin FX and Its Successors

The post-Second World War period truly cemented the image of the London taxi with the advent of the Austin FX series, a collaboration that would define the industry for decades. The story began with the experimental prototype FX in 1945, developed by Austin, the coachbuilders Carbodies of Coventry, and London taxi dealers Mann and Overton. This was quickly followed by the FX2, featuring an all-new chassis and a 1.8-litre engine.

The true game-changer was the Austin FX3, available from 1948 to 1958. Offered with a 2.2-litre petrol engine and an all-steel body from Carbodies, it became the first widely adopted post-war London taxi. Its success prompted Austin to develop its own diesel engine for it in 1956. During this same period, the Morris Oxford cab, built at the Wolseley factory, was also introduced (1947-1955). Approximately 1800 Oxfords were built, making it the first new cab offered after WWII. However, with the merger of Morris and Austin to form the British Motor Corporation in 1952, the Oxford was discontinued in favour of the FX3, to avoid internal competition.

But it was the Austin FX4 that would become the quintessential London black cab. Appearing in 1958, this ubiquitous vehicle, initially with a 2.2-litre diesel engine and automatic gearbox as standard, remained in production, albeit heavily modified, until 1997. Alongside the Mini, it stands as one of the longest-lived British motor designs. Its evolution was continuous: a gasoline-powered version was introduced in 1961, and the diesel version saw engine changes from the BMC K series to the British Leyland 25V from 1971. Later iterations included the FX4D, FX4R (fitted with a Land Rover diesel from 1982-1985), and the FX4Q (using reconditioned parts and the older Austin engine). Carbodies eventually bought the intellectual rights to the FX4 and produced it under their own name. The FX4 also saw significant advancements, notably the Fairway version, introduced in 1989, which was the first FX4 to be wheelchair accessible, powered by a Nissan 2.7-litre diesel engine. The last Fairway, marking the end of the FX4 era, rolled off the production line in October 1997.

Other notable cabs during this period included the Beardmore Mark VII (1954-1967), which, despite its traditional appearance, was advanced for its time, constructed of aluminium and glassfibre with Ford Consul running gear. Approximately 650 Mark VIIs were built. Birch Brothers, a cab operator, even developed a prototype four-door cab in 1954, though only one was made.

Modern Era: Diversity and Continued Innovation

As the FX4's reign drew to a close, new designs emerged to meet evolving regulations and passenger expectations. London Taxis International (LTI), formed when Carbodies' owner acquired Mann and Overton, continued the legacy. The TX1, introduced in October 1997, built on the Fairway Driver's running gear but featured an all-new five-seat body, signifying a modern successor to the FX4. The name TX1 was a clever nod to Austin's old numbering system, essentially "TAXI" with the 'A' removed.

Another significant player in the modern era was the Metrocab. Based on early work for the Beardmore Mark VIII, the MCW Metrocab was introduced in 1987. This fibreglass-bodied cab, powered by a 2.5-litre Ford Transit diesel engine, was revolutionary as the first London cab to be fully wheelchair accessible and licensed to carry four passengers. The Metrocab continued to evolve under different ownerships (Reliant, Hooper), introducing features like disc brakes as standard in 1992 and restyled Series II models, eventually adopting a turbocharged Toyota engine in 2000.

Some other interesting, though less common, ventures included the US-assembled London Coach (1985-1987), which used Carbodies glider kits and Ford engines for the American market, and various prototypes like the electric Lucas cab (1975) and the Eurotaxi (hybrid fuel vehicle). Even Mitsubishi attempted a conversion of their L300 van into a taxi, but it failed to meet the PCO's stringent turning circle requirements.

How Many London Taxis Were Made? A Glimpse into Production Figures

While an exact cumulative total of all London taxis ever produced is elusive, the provided information offers insights into the scale of production for specific models and manufacturers throughout history. These figures paint a picture of the industry's growth and the impact of certain designs:

• Bersey Electric Cabs (1897-1898): 70 units
• Austin Edwardian Cabs (1907 model): 10 units (for Taxi DeLuxe Company)
• Renault Cabs (1907, General Motor Cab Company): 500 units
• BSA Cycle Cabs (1920-1925): Limited number, likely up to 100 (frame numbers W1-W100)
• Cape Cabs (1929-1936): Over 100 units
• Morris Oxford (1947-1955): Approximately 1800 units
• Beardmore Mark VII (1954-1967): Approximately 650 units
• London Coach (1985-1987, US market): Estimated 80-100 units

The FX4 series, spanning from 1958 to 1997, represents by far the largest production volume of any single London taxi model. Although specific total figures are not provided, its nearly four decades of continuous production and multiple iterations suggest tens of thousands, if not hundreds of thousands, were manufactured, making it an unprecedented success in automotive history and truly the most iconic London taxi.

The evolution of London's cabs is a testament to continuous adaptation and a commitment to public service. From early, experimental electric vehicles to the enduring and adaptable petrol and diesel workhorses, each era brought forth new designs and technological advancements, shaping the distinct character of London's transport landscape. The black cab's journey is far from over, as it continues to evolve with new powertrains and designs, ensuring its place as a quintessential part of the city for generations to come.
