Description

The Austin FX4D Taxi 2.5 Diesel was a defining workhorse of British city life, especially throughout the 1970s and into the early 1980s. As part of the long-running FX4 series that first debuted in 1958, the FX4D introduced a more economical and practical diesel alternative to the earlier petrol models, meeting the growing needs of professional cab drivers for efficiency and longevity.

This version was powered by a 2.5-litre diesel engine, typically the BMC (later British Leyland) diesel unit. While performance wasn’t exactly spirited—the engine delivered modest horsepower and a deliberate pace—it was durable and reliable, capable of racking up hundreds of thousands of miles in the constant stop-and-go of city driving. Fuel economy was one of its biggest selling points, making it a preferred choice for long shifts and high-mileage days.

The FX4D kept the classic FX4 body styling: a tall, upright design with large round headlights, a stately chrome grille, and generous proportions. Its roofline accommodated even passengers wearing bowler hats, while the rear passenger compartment was designed with practicality in mind. It featured wide-opening rear-hinged doors, a flat floor, and enough space to seat three adults in comfort, along with two occasional jump seats for extra capacity.

Another standout feature was its legendary turning circle—just 25 feet—which allowed it to perform U-turns on narrow London streets with ease, satisfying the city’s strict taxi licensing requirements. The car’s ride was smooth and forgiving, thanks to its robust suspension and chassis designed to take on the rough and tumble of daily urban use.

Despite its utilitarian nature, the FX4D had an undeniable charm. It exuded a kind of modest dignity, becoming an instantly recognizable symbol of London. The diesel clatter was part of its character, and even though it wasn’t fast or flashy, it was dependable and always ready to serve.

Over time, the FX4D evolved with improved engines and trims, eventually being succeeded by the FX4R and the Fairway models. But the 2.5 Diesel version remains a favorite among enthusiasts and collectors for its honest engineering and its role in shaping the golden era of the London black cab.
