The history of MG

MG has a long-standing enthusiast following. For a century, the octagonal badge is associated with affordable, accessible sports cars. From hand-built two-seaters in 1920s Oxford to today's electric hatchbacks, MG survived wars, bankruptcies, and multiple ownership changes, but its core promise has not changed. Whether as a chrome-bumpered roadster on a country lane or a zero-emission city car on a modern forecourt, MG links generations of drivers who believe performance should be within reach of ordinary buyers. This is the full account of how a small British marque became a global brand, and where it is heading next.

The founding years: 1920s origins in Oxford

MG's story begins in 1924, when William Morris and his employee Cecil Kimber began building sportier versions of standard Morris cars at a small workshop in Oxford. The name "MG" stood for Morris Garages, the dealership Kimber managed. Their first true production model, the 14/28, was a modified Morris Oxford with a tuned engine, lowered suspension, and distinctive coachwork. It was quick by the standards of the day and, importantly, affordable, setting a template MG would follow for decades.

By the late 1920s, demand had grown enough to justify a dedicated factory at Abingdon-on-Thames, which would remain MG's spiritual home for over fifty years.

1930s: Racing glory and the birth of a community

The 1930s changed MG from a niche modifier into a sporting name. The MG Car Club was founded during this period, creating a large owner community. On the track, MG punched well above its weight: the supercharged K3 Magnette won its class at the 1933 Mille Miglia, a notable result for a small-capacity British car competing against established Italian marques.

The K3 confirmed MG's ability to build cars that could race and win against far more expensive rivals.

1940s–1950s: Post-war boom and American love affair

After World War II, MG capitalised on American demand for small, nimble sports cars. The TC Midget became a sensation in the United States, with returning GIs who had encountered British sports cars in Europe eager to buy their own. Around 10,000 TCs were built, and a significant proportion were exported across the Atlantic, which helped create the American sports-car culture that flourished in the 1950s and 1960s.

In 1952, MG was absorbed into the British Motor Corporation (BMC) following a takeover. While some enthusiasts worried about corporate dilution, the move gave MG access to BMC's A-series and B-series engines, enabling landmark models. The MGA, launched in 1955, was a clean-sheet design with aerodynamic bodywork that looked nothing like its pre-war ancestors. A year later, in 1956, the 100,000th MG rolled off the line, a milestone that confirmed the brand's commercial success.

1960s–1970s: The MGB era and a million cars

The MGB, introduced in 1962, became the definitive MG and one of the best-selling sports cars ever made. Its monocoque construction was modern, its handling sharp, and its price accessible. Over its 18-year production run, more than 500,000 MGBs were built in roadster and GT coupé forms.

During this period, production of badge-engineered saloons moved to Longbridge, and models like the MG 1100 and MG 1300 brought the octagon to family-car buyers. These were not sports cars, but they outsold every MG roadster and showed the badge had broad commercial appeal.

In 1975, MG celebrated the production of its one-millionth car, a notable achievement for a brand that had started life in a back-street garage.

1980s–1990s: Closures, ownership turmoil, and survival

The late 20th century was turbulent for MG. The Abingdon factory closed in 1980, ending roadster production. The MG name survived on badge-engineered versions of the Metro, Maestro, and Montego, hot hatches and saloons that kept the brand visible, if not glamorous.

Ownership passed through British Leyland, the Rover Group, and eventually BMW, which acquired Rover in 1994. BMW invested in the MG F, a mid-engined roadster launched in 1995 that was the first all-new MG sports car in decades. It was well received, but BMW's broader struggles with Rover left the future uncertain.

2000s: MG Rover, the TF, and administration

When BMW divested Rover in 2000, the MG Rover Group attempted to go it alone. The MG TF, an updated version of the F, was launched and sold respectably. But without the financial backing of a major parent, MG Rover could not sustain itself. The company entered administration in April 2005, and Longbridge fell silent.

The MG name and assets were purchased by China's Nanjing Automobile Group, which subsequently merged with SAIC Motor, one of China's largest automotive conglomerates and a Fortune Global 500 company.

Racing and cultural legacy

MG's motorsport heritage runs deep. Beyond the K3's Mille Miglia result, MGs competed at Le Mans, in rallying, and in countless club events. The MG Car Club remains one of the largest single-marque clubs in the world, and events like MG Live! draw thousands of enthusiasts annually.

Culturally, the MG roadster became a shorthand for a particular kind of British motoring pleasure, wind-in-the-hair driving on a budget. The brand has appeared in films, television, and literature as a symbol of accessible adventure. The British Motor Museum at Gaydon houses an extensive collection of historic MGs, preserving this legacy for future generations.

• 2005 — Administration; assets acquired by Nanjing Automobile
• 2007 — Nanjing merges with SAIC Motor; MG becomes an SAIC brand

MG today and the electric future

Under SAIC ownership, MG has been reborn as a volume brand with global reach. Production shifted primarily to China, though a small-scale assembly operation briefly returned to Longbridge. The MG6 GT marked the brand's return to UK showrooms, followed by the MG3 supermini and the MG GS crossover.

Electrification changed the brand. The MG ZS EV, launched in 2019, became one of the UK's most affordable electric SUVs and helped MG climb the sales charts. The MG4 hatchback, introduced in 2022, received critical praise, and Autocar and Top Gear noted its sharp handling and competitive pricing. By 2023, MG was one of the top-selling brands in the UK, a position it had not held in decades. Arnold Clark regularly lists MG models in its UK showrooms and online, which has made those EVs accessible to mainstream buyers.

Looking ahead, MG's pipeline includes the Cyberster, an electric two-seat roadster that echoes the brand's sporting heritage, alongside further EV and plug-in hybrid models aimed at making zero-emission driving affordable.

Why collectors love MG

• Affordable entry point — Classic MGs, particularly MGBs and Midgets, remain among the most accessible classic sports cars to buy and maintain.
• Huge parts availability — Decades of production and a dedicated aftermarket mean spares are plentiful and reasonably priced.
• Active community — The MG Car Club and MG Owners' Club offer technical support, events, and camaraderie.
• Simple mechanicals — Most classic MGs use straightforward, easy-to-work-on engines and running gear, ideal for home mechanics.
• Investment potential — Early pre-war models and low-production variants like the MGA Twin Cam have appreciated significantly, while even standard MGBs have risen steadily in value.

Conclusion: a century of affordable thrills

From Cecil Kimber's hand-modified Morris Oxfords to SAIC's electric hatchbacks, MG's story is one of reinvention while keeping a founding principle: great driving should be within everyone's reach. A century on, that idea remains relevant. Arnold Clark stocks a range of new and used MGs across the UK and can help you explore the range.
