Description

The Daimler DB18 Special Sports Drophead Coupé was a stylish and refined open-top touring car produced in the immediate post-war period, reflecting Daimler’s effort to reassert itself in the luxury car market after the disruptions of World War II. Introduced around 1948, the Special Sports variant was a more performance-oriented and visually dynamic evolution of the standard DB18, aimed at affluent customers seeking both elegance and driving enjoyment.

This model retained Daimler’s proven 2.5-litre inline-six engine but featured significant mechanical enhancements. The engine was fitted with twin SU carburettors in the Special Sports version, boosting its output compared to the standard DB18 saloon. While still not a sports car in the traditional sense, the additional power made for more spirited performance, especially when paired with the lighter and more aerodynamic drophead coupé body.

The transmission remained Daimler’s distinctive pre-selector gearbox with a fluid flywheel, offering smooth and leisurely gear changes that suited the car’s luxury character. While some might find the system unusual by modern standards, it was appreciated at the time for the effortless driving experience it provided, particularly in urban or touring environments.

The bodywork for the Special Sports Drophead Coupé was designed by coachbuilder Barker, which had been acquired by Daimler in the 1930s. Barker crafted an elegant, flowing design with a long bonnet, gracefully curving fenders, and a clean rear deck that complemented the folding fabric roof. When raised, the hood gave the car a formal profile; when lowered, it revealed a spacious and luxurious open-air cabin, ideal for relaxed motoring in good weather.

Inside, the drophead coupé was trimmed to a high standard with leather seats, polished wood veneers, and full instrumentation. The layout was traditional, with front seats for the driver and a passenger, and occasional seating in the rear, making it a 2+2 rather than a full four-seater. The finish and fittings were all in keeping with Daimler’s focus on quality and craftsmanship.

The DB18 Special Sports Drophead Coupé was well received in both domestic and export markets, particularly in Commonwealth countries where British luxury cars held considerable prestige. Its blend of refinement, open-top style, and modest performance enhancement made it an attractive alternative to the more staid saloons and limousines in Daimler’s range.

Production continued into the early 1950s before it was succeeded by the more modern Daimler Conquest Roadster. However, the DB18 Special Sports remains notable for marking Daimler’s return to building handsome, upper-class tourers after the war.

Today, surviving examples of the Daimler DB18 Special Sports Drophead Coupé are rare and desirable among classic car enthusiasts. Their graceful styling, historical significance, and association with post-war British elegance make them a welcome sight at vintage car events and concours displays. Restored models, in particular, showcase the quiet dignity and craftsmanship that defined Daimler’s post-war identity.
