Description

The Bristol 405 D, sometimes referred to as the 405 Drophead Coupé, is one of the rarest and most elegant models ever produced by the Bristol Aeroplane Company’s car division. Based on the four-door 405 saloon introduced in 1954, the 405 D was a two-door, open-top version that combined the refined engineering of the saloon with the glamour and freedom of convertible motoring. Only 43 examples of the 405 D were ever built, making it not just a collector’s dream but also a truly exclusive piece of British motoring history.

While the saloon version was notable for being the only four-door Bristol of its era, the drophead variant offered a more relaxed, grand touring experience. The design was executed with exceptional care: the folding fabric roof was neatly integrated, and when lowered, it maintained the car’s graceful proportions. Unlike many convertibles of the period, the 405 D retained much of the structural integrity of the saloon thanks to Bristol’s meticulous construction standards, resulting in a car that felt solid and composed on the road.

Under the bonnet, the 405 D was powered by Bristol’s trusted 2.0-litre straight-six engine, based on the legendary BMW 328 design. Typically tuned to produce around 105 to 125 bhp, it delivered smooth and flexible performance, complemented by a four-speed gearbox with full synchromesh. This drivetrain, combined with the car’s light construction and balanced chassis, gave the 405 D refined, confidence-inspiring road manners—ideal for both country touring and urban cruising.

The interior of the 405 D reflected Bristol’s usual high standards of craftsmanship, featuring beautifully tailored leather seats, finely polished wood trim, and aircraft-inspired instrumentation. The two-door layout and convertible roof lent the cabin a more intimate and sporting atmosphere, while still offering comfort for long-distance drives.

Today, the Bristol 405 D stands as one of the marque’s most desirable classics. With its rarity, open-top appeal, and unmistakable mid-century styling, it represents a harmonious blend of British engineering, understated luxury, and post-war optimism—an enduring symbol of Bristol’s uniquely crafted approach to motoring.
