Austin A 40 Classic Cars for Sale

History of the Austin A 40

Introduced in 1947, the Austin A40 marked a decisive step into the post-war era for the Austin Motor Company. Succeeding the Austin 8 and 10, the A40 series was designed for daily practicality yet reflected the company’s tradition of naming vehicles after English counties, starting with the Dorset. Early models combined some pre-war technical solutions, such as a separate ladder frame, with a new 1.2-litre four-cylinder engine. These reliable vehicles quickly won buyers with their balance of affordability, simplicity and solid engineering. Over time, the A40 line evolved, spawning multiple variants that embraced changing customer tastes, technical advancements and even collaborations—like the Jensen-bodied A40 Sports, which completed a marketing world tour in just 21 days. By the end of its run in the late 1960s, the A40 series had seen production numbers in the hundreds of thousands, cementing its place in British automotive history.

Model History

The first A40, the Dorset, was a simple two-door saloon, closely followed by the four-door Devon and the practical three-door Countryman estate. These early versions shared the newly introduced 1.2-litre engine producing around 40 hp. In 1950, the A40 Sports was developed in partnership with Jensen Motors—a lightweight, aluminium-bodied convertible that pushed performance to 46 hp. Production numbers were small, with just over 4,000 made. The 1952 Somerset introduced modest improvements, including a column gear change and minor power enhancements, but also drew criticism for lacklustre dynamics. From 1954, the A40 Cambridge brought a more contemporary look and improved independent front suspension. The last A40 to be produced under this name was the Farina, styled by Pininfarina and available from 1958, blending stylish lines with compact hatchback practicality. International adaptations, notably by Innocenti in Italy, extended the A40’s life until 1967.

Highlights and Special Features

Several aspects set the Austin A40 apart within its class: the Jensen-developed Sports convertible with aluminium bodywork, the flexible utility of the Countryman estate, and the Somerset’s cabriolet variant all contributed to an unusually broad model range. Throughout its life, the A40 demonstrated a pragmatic approach—stressing reliability and practical motoring over unnecessary complexity. Unique to the Sports model is its global tour, showcasing both publicity and engineering stamina. Another highlight is the introduction of independent front suspension on the Cambridge, improving both comfort and handling. The Pininfarina-designed A40 Farina served as a blueprint for the modern hatchback, showing just how innovative this model series could be.

Special Editions and Collectible Models

The Austin A40 Sports is the most notable special edition within the series. Built in cooperation with Jensen Motors from 1950 to 1953, its aluminium body and improved performance make it a rare and highly distinctive submodel, with only about 4,011 units produced. Cabriolet versions of the Somerset and Cambridge, as well as the Italian Innocenti-built A40 Countryman and A40 S, are also of interest due to production volumes, body styles and international variations.

Engine, Performance and Handling

All A40 models deliver usable torque and adequate acceleration for their era, with the Sports reaching up to 46 hp and speeds around 130 km/h. While the Devon and Somerset focus on comfort, the Sports model’s lightweight aluminium construction and improved carburation set it apart in terms of driving feel. A40 Farina and Cambridge variants, equipped with independent front suspension and enhanced gearboxes, offer superior ride comfort and more predictable handling—making them enjoyable for relaxed long-distance drives. Drum brakes on all four corners mean stopping distances are longer by modern standards, so careful planning is required. - A40 Devon: Practical four-door saloon with 40 hp, produced in high numbers; valued for reliability.

Interior, Comfort, Exterior and Design

A40 interiors are pared-down but cleverly functional, featuring two-tone dashboards and classic leather seats. Materials are honest, prioritising durability—expect hard-wearing trim suitable for practical daily use. The exterior design evolves significantly within the series: from the pre-war influenced Devon and Somerset with rounded wings and high roofs, to the more streamlined Cambridge with its integrated wings and full-width grille. The A40 Farina stands out most—the Pininfarina design introduced a hatchback body style ahead of its time. Paintwork was originally available in sober period hues such as black or dark blue, though many examples have been repainted. The A40 Sports is instantly recognisable thanks to its unique aluminium body, prominent "Austin of England" badge and Flying A bonnet mascot.
