Austin FL2

Overview

The Austin FX4 was introduced in 1958 as the replacement for the FX3, designed by Eric Bailey of Carbodies and engineered to meet the strict Public Carriage Office (PCO) requirements for London taxis — including the celebrated 25-foot turning circle (approximately 7.6 metres) that allows London cabs to perform U-turns in regulation-width streets. The vehicle was built by Carbodies of Coventry under the Austin (and later British Leyland) name.

The FL2 designation referred specifically to a variant of the FX4 platform built for hire car use outside the strict London cab licensing conditions — effectively the same mechanical package with minor variations to suit non-metered private hire operations. The FL2 was sold in various export markets where the silhouette of a “London cab” was a commercial asset, and in some Soviet and post-Soviet markets these vehicles arrived as exports or diplomatic vehicles.

The FX4/FL2 platform remained in production — with many updates — from 1958 until 1997, an almost unparalleled 39-year run for a single vehicle concept. Engine choices evolved from the original 2.2-litre Austin petrol unit through a 2.5-litre diesel, a Perkins diesel, and eventually a Land Rover-derived 2.5-litre diesel. Throughout its life the fundamental body-on-frame, rear-wheel-drive architecture never changed.

In Azerbaijan, an Austin FL2 or FX4 would be an extraordinary collector’s piece — a living symbol of London transported to the Caspian coast, with all the immediate recognition that the classic cab silhouette carries worldwide.

• Drivetrain: Rear-wheel drive with live rear axle — conventional taxi-cab architecture for robustness.
• Turning circle: 7.6 metres (25 feet) — the legendary PCO-compliance turning ability.
• Body construction: Body-on-frame; steel body by Carbodies, Coventry.
• Passenger capacity: 5 passengers in the rear compartment; fold-down occasional seats (jump seats) for 2 additional.
• Luggage: Front boot (bonnet-mounted luggage compartment) supplemented by rear passenger area storage.
• Partition: Glass partition between driver and passenger compartment standard; sliding glass window for communication.

FX4 / FL2 Variants by Era

What Makes the FL2 / FX4 Stand Out

• Global iconic status: No other taxi is as universally recognised as the London black cab — ownership commands immediate attention anywhere in the world.
• Extraordinary turning circle: The 7.6-metre turning circle is a genuine engineering achievement designed to PCO specification — unique among production vehicles of the era.
• 39-year production run: The FX4 platform was in continuous production from 1958 to 1997 — a testament to the fundamental rightness of its purpose-built design.
• Passenger compartment: The spacious, separate rear compartment with fold-down occasional seats and large door openings is designed for passenger dignity — far superior to any conventional car-based taxi.
• Mechanical simplicity: The body-on-frame construction, conventional drivetrain, and straightforward engine choices make the FX4 one of the most repairable classic vehicles of its era.

Repair & Service in Azerbaijan

The Austin FX4/FL2 is mechanically straightforward — arguably simpler than almost any contemporary vehicle. The diesel engines (Perkins and Land Rover variants) are proven workhorses with long service lives and reasonable parts availability. In Baku, any diesel mechanic with experience on Land Rover or Perkins engines can service the later FX4 variants without specialist training.

• Land Rover 2.5 diesel: Later FX4 models use a Land Rover-derived engine; Land Rover diesel parts are available in Azerbaijan through 4x4 specialist suppliers.
• Body construction: The steel-over-frame body is heavy but repairable; local panel beaters can work on the straightforward body panels without specialist tooling.
• Rust: Like all British-built vehicles of the era, the FX4 is susceptible to corrosion; thorough underbody inspection is essential.
• Specialist parts: FX4/FL2-specific parts (door mechanisms, partition glass, meter fittings) are sourced from UK specialists who supply worldwide.
• Gearbox: The manual gearbox is a robust, straightforward unit; automatic variants use Borg-Warner boxes with reasonable parts availability.
• Local attention: A black London cab in Baku will attract considerable attention and goodwill from mechanics and the public alike — a genuine asset for an owner seeking help.

Buying Checklist

• Frame condition: Inspect the body-on-frame chassis thoroughly for corrosion, weld repairs, and structural integrity.
• Engine type: Identify which engine is fitted (petrol, Perkins diesel, or Land Rover diesel) as parts availability varies significantly by era.
• Diesel system: Check fuel injection pump condition, glow plugs, and start-up behaviour; diesels that have sat unused develop injection pump issues.
• Partition glass: Confirm the sliding partition glass is intact and operates correctly — replacements require UK specialist sourcing.
• Passenger doors: The wide rear doors with their distinctive opening mechanism must operate smoothly; check hinges and latching.
• Meter and fittings: Confirm whether original taxi fittings (meter, radio, signage) are present if originality matters.
• Body rust: Sills, wheel arches, and floor sections; the body-on-frame construction means rust is manageable if caught early.

Austin FL2 / FX4 FAQ

What is the difference between the Austin FX4 and the FL2?

The FX4 was the licensed London taxi variant, required to meet the strict Public Carriage Office (PCO) regulations including the 25-foot turning circle. The FL2 was a hire car variant built on the same platform for use outside the London taxi licensing conditions — typically for private hire operators who wanted the cab’s passenger space and recognised silhouette without the formal taxi licensing constraints. Mechanically and visually they are virtually identical.

How practical is a London cab for daily use in Baku?

Surprisingly practical for certain uses. The exceptional turning circle makes it outstanding in Baku’s congested city streets. The high roofline and wide door openings make entry and exit exceptionally easy. Diesel economy on later models is reasonable. The main limitation is the low top speed and the unusual driver position, which takes acclimatisation. As a short-distance city vehicle or show car, it is a genuine conversation piece.

Can I find parts for an FX4/FL2 in Azerbaijan?

Land Rover 2.5 diesel engine parts can be sourced locally through 4x4 and Land Rover specialists. FX4-specific body and trim parts require UK sourcing via specialists such as Asquith Motor Carriages or cab parts suppliers. The vehicle’s mechanical simplicity means that many consumable parts (belts, filters, brakes) can be sourced locally by cross-referencing Land Rover or Perkins part numbers.

Should You Buy an Austin FL2 / FX4?

The Austin FL2/FX4 is the right choice for a collector who wants maximum public recognition from a classic commercial vehicle, an easy-to-repair diesel workhorse with genuine historical significance, and a vehicle that generates warmth and goodwill wherever it goes. In Baku, a London cab is unique — no other owner in the city has one.

It is not the right choice for someone who wants performance, comfort comparable to a modern vehicle, or effortless parts sourcing. The FX4/FL2 rewards patience, a degree of mechanical sympathy, and an appreciation for the purposeful, London-street engineering philosophy that kept this design in production for 39 years.
