Description

The Bristol 406, introduced in 1958, marked a significant transition for the Bristol marque as it sought to evolve from its post-war sporting saloon roots into a more mature and refined grand tourer. It was the final Bristol to be powered by the company’s long-serving 2.0-litre straight-six engine, originally derived from pre-war BMW designs, and represented the culmination of that engine’s development. The 406 also introduced several technical advancements and a more modern, understated design language that would influence future models.

Visually, the 406 retained the classic Bristol proportions—long bonnet, short rear deck, and clean, flowing lines—but with softer, more rounded styling compared to its predecessor, the 405. The bodywork featured integrated headlamps, a wider grille, and smoother contours that reflected the changing tastes of the late 1950s. Despite these updates, the 406 retained Bristol’s traditional handcrafted elegance, with fine detailing and an emphasis on aerodynamics and functionality.

Mechanically, the 406’s most notable change was the introduction of disc brakes on all four wheels, making it one of the earliest British production cars to offer this feature as standard. This significantly improved stopping power and safety, aligning the car with the technical advancements seen in motorsport and high-end European rivals. The 2.0-litre engine, in its final form, produced around 105 bhp and was mated to a four-speed gearbox with optional overdrive, offering smooth and flexible performance. Though no longer a sports saloon in the traditional sense, the 406 delivered relaxed, confident cruising rather than outright speed.

Inside, the cabin continued Bristol’s tradition of combining luxury with a sense of purposeful design. High-quality leather seats, polished wood trim, and clear, aircraft-inspired instrumentation created an environment of quiet sophistication. Comfort and long-distance touring ability were prioritized, with improved insulation and more spacious accommodations.

The Bristol 406 was produced in relatively small numbers, with only 174 examples built, underscoring its exclusivity. Today, it is appreciated for its blend of classic styling, mechanical refinement, and historical significance as the final model to use Bristol’s iconic six-cylinder engine before the company transitioned to V8 power in the 407. The 406 stands as a refined farewell to Bristol’s first engineering era.
