The LTI TXI 2.7 D, producing 82 horsepower, was a variant of the TX series produced by the London Taxi International (LTI) company between 1998 and 2002. This model represented a continuation of the iconic London “black cab,” specifically the TXI generation (HX platform), designed to meet the stringent requirements of professional taxi operation in the United Kingdom and export markets. The 2.7 D variant occupied a position as a workhorse option within the TXI lineup, prioritizing fuel efficiency and durability over outright performance, making it a popular choice for high-mileage use. It was positioned below the more powerful petrol (gasoline) engine options, and served as a more economical alternative.

Powertrain & Engine Architecture
The heart of the TXI 2.7 D was a 2.7-liter inline-four cylinder diesel engine. This engine, often identified by its engine code, was a robust and relatively simple design intended for longevity and low maintenance. It utilized a precombustion chamber injection system, a common diesel technology of the era, which involved injecting fuel into a small pre-chamber within the cylinder head before the main combustion chamber. This aided in cold starting and improved combustion efficiency. The engine featured a single overhead camshaft (OHC) valvetrain operating two valves per cylinder. The 5-speed manual transmission was the standard offering, chosen for its durability and cost-effectiveness. The transmission was geared towards providing adequate acceleration with a full passenger load, rather than outright speed.
Driving Characteristics
The 82 horsepower output of the 2.7 D engine translated to modest, but adequate, performance for its intended purpose. Acceleration was not brisk, and the vehicle was geared towards smooth, predictable operation rather than sporty driving. The manual transmission, while durable, required frequent shifting in urban environments to maintain optimal engine speed. Compared to the petrol engine options available in the TXI range, the 2.7 D offered significantly less power, but a noticeable improvement in fuel economy. The gear ratios were optimized for pulling away from a standstill with passengers and luggage, and for maintaining a steady cruising speed on highways. The rear-wheel drive configuration provided predictable handling, but required careful driving in slippery conditions.
Equipment & Trim Levels
The TXI 2.7 D was typically equipped with a functional, rather than luxurious, interior. Standard features included cloth upholstery, a basic instrument panel, and manually adjustable windows and mirrors. Air conditioning was often an optional extra, as was a radio/cassette player. The focus was on providing a comfortable and durable environment for both the driver and passengers. Trim levels were relatively limited, with most variations stemming from optional extras chosen by fleet operators or individual owners. The interior was designed for ease of cleaning and maintenance, reflecting the demands of taxi service.
Chassis & Braking
The TXI chassis was a body-on-frame construction, providing a robust and durable platform. The front suspension utilized a double wishbone setup, while the rear suspension employed a traditional leaf spring arrangement. This combination offered a comfortable ride, particularly on uneven road surfaces, and was well-suited to the high mileage typically accumulated by taxis. The braking system featured ventilated discs on the front wheels and drum brakes on the rear. Anti-lock braking system (ABS) was included as a standard safety feature. The steering was a rack and pinion system with hydraulic power assistance, providing relatively light and precise steering control.
Market Reception & Comparison
The LTI TXI 2.7 D was generally well-received by taxi operators and fleet buyers who prioritized fuel economy and reliability. Critics acknowledged the engine’s lack of outright power, but praised its durability and low running costs. Compared to the petrol-powered TXI variants, the 2.7 D offered significantly better fuel economy, making it a more cost-effective option for high-mileage applications. However, the petrol engines provided a smoother and more refined driving experience. The diesel variant also faced competition from other taxi models, such as the Ford E7, but the TXI maintained its position as the dominant taxi in London and many other cities.
Legacy
The LTI TXI 2.7 D, while superseded by later models, remains a recognizable and respected vehicle in the taxi trade. The 2.7-liter diesel engine proved to be remarkably durable, and many examples are still in service today, albeit often with significant mileage. In the used car market, these vehicles are valued for their simplicity, reliability, and relatively low maintenance costs. However, potential buyers should be aware of the age of the vehicles and the potential for wear and tear on components such as the suspension and braking system. The TXI 2.7 D represents a significant chapter in the history of the London black cab, embodying the qualities of robustness and practicality that have defined this iconic vehicle for generations.
