Sunbeam 20/60 Classic Cars for Sale

Introduction and history of Sunbeam 20/60

Sunbeam, a key player in British automotive history, introduced the 20/60 model in the late 1920s as part of its drive to compete in the premium market. The car combined advanced engineering for its time—most notably a robust inline-six engine—with the marque's traditions of quality construction and understated luxury. Sunbeam’s reputation was built on motorsport successes and innovation, and the 20/60 formed part of an evolution that solidified the brand’s prestige between the wars.

Model history

The Sunbeam 20/60 was the evolution of the company’s earlier six-cylinder vehicles and represented a step up in terms of displacement and comfort. The car’s architecture would influence later Sunbeam models, and while production numbers remained limited compared to mass-market brands, the 20/60 filled the niche for discerning drivers seeking a British touring car with genuine engineering merit. Sunbeam’s history after the 20/60 would eventually merge into the broader Rootes Group lineage.

Highlights of Sunbeam 20/60

The Sunbeam 20/60 is distinguished by its balanced chassis, silent running engine, and a focus on long-distance comfort for its era. Unlike many contemporary vehicles, it offered hydraulic brakes as standard and spacious interiors with high-quality materials. The car’s 3-litre six-cylinder engine delivered consistent torque, making it suitable both for urban surroundings and open-road touring.

Special Editions and Collectible Models

Special versions of the Sunbeam 20/60 were produced with bespoke coachwork by respected British coachbuilders. Examples include unique drophead coupés and limousines tailored for individual clients, making some cars rare survivors with significant historical value. Many of these special editions can be distinguished by their hand-crafted details and specific trim elements, which were often customised on request.

Engine and Performance, Transmission and Handling

Period road tests praised the Sunbeam 20/60 for its smooth power delivery and flexible performance across various driving conditions. The car’s six-cylinder engine is known for reliability, provided regular servicing is followed. The manual transmission is solid but requires precise operation, as with most pre-war gearboxes. Hydraulic brakes marked a notable improvement in active safety, uncommon in its competitive set. The model’s suspension configuration—semi-elliptic leaf springs all round—provides stable handling by vintage standards, but requires regular attention to maintain alignment and ride quality. The standard touring saloon and bespoke-bodied coupé versions of the 20/60 are especially noted for combining comfort with robust period performance.

Interior, Comfort, Exterior and Design

Sunbeam 20/60 models are typically finished with high craftsmanship, sporting hand-built bodies tailored by coaches such as Thrupp & Maberly or Weymann. Interiors are classic: polished wood dashboards, leather upholstery, and analog instrument clusters. Distinctive design details include wire wheels, sweeping fenders, and a stately radiator grille. Factory accessories of the period may include extra lamps, motoring tools, and period-specific storage solutions. The exterior finishes usually featured deep enamelled paints, and custom orders were common for clients seeking distinct hues and elegant details.

Summary

The Sunbeam 20/60 is a rare sight today, capturing the essence of British engineering from the late 1920s and early 1930s. Its exclusivity within the classic car market, together with period luxury and mechanical sophistication, makes it particularly attractive to collectors who appreciate authenticity and quality craftsmanship. With its commanding presence and considered engineering solutions, the 20/60 echoes a bygone era for enthusiasts who value genuine classics.
