Discover how iconic London black cabs are evolving with electric and plug-in technology, shaping the future of city transport.
For generations, the iconic black cab has been an enduring symbol of London’s rich history and bustling city life. But in recent years, these Hackney carriages have undergone a remarkable transformation: powered now not only by the skill of their drivers, but by batteries and forward-thinking engineering. The electrification of London’s cabs signals a pivotal shift towards cleaner, more efficient, and accessible city transport—benefiting drivers, passengers, and the environment alike.
The Transformation: From Diesel to Electric
Historically dominated by the distinctive, diesel-powered models, London’s streets are now seeing a new breed of cab—the electric and plug-in hybrid. This shift aligns both with the global movement towards carbon neutrality and London’s own efforts to combat poor air quality and urban congestion. Transitioning to electric is not just a technical upgrade; it represents a critical step towards sustainable urban living, offering reduced exhaust emissions, lower noise pollution, and new opportunities for mobility innovation.
The LEVC TX: A New Era of Black Cab Design
The centerpiece of this transition is the LEVC TX, manufactured by the London Electric Vehicle Company (LEVC). Designed from the ground up as a plug-in hybrid electric vehicle (PHEV), the TX combines a pure electric drive mode with a range-extender petrol engine, enabling:
- All-electric driving range of 78 miles—sufficient for the majority of inner-London journeys.
- Total range of over 300 miles with the range extender, eliminating range anxiety for drivers.
- Zero-exhaust emission capability during electric operation.
- Spacious, flexible cabin with accessibility features for all passengers.
- Signature turning circle—retaining the legendary maneuverability essential for central London’s narrow streets.
More than 11,000 LEVC TX cabs have now hit the roads globally since the model’s introduction, with over 8,600 operating in London itself. The electric TX now accounts for more than 60% of the capital’s taxi fleet, having overtaken the older, diesel-powered TX4 in vehicle share. These cabs together have covered more than one billion miles, saving an estimated 300 million kilograms of CO2 emissions compared to their diesel predecessors.
Engineering and Driving the Future Black Cab
The TX is purpose-built for both sustainability and practicality, integrating modern electric-vehicle technology with proven cab features:
- Range-Extended Electric Vehicle (REEV) design pairs batteries with a 1.5L petrol engine solely as a generator, not for direct propulsion.
- Rapid charging—a fast-charging port allows top-ups during typical cabbie breaks.
- Durability—built to withstand the heavy-duty daily mileage of professional taxi operations, with some cabs clocking over 280,000 miles without major issues.
- Passenger comfort and accessibility—including wheelchair access, USB charging, panoramic sunroof, and ample luggage storage.
Critically, the TX is the only fully-accessible taxi currently available on London roads, meeting the city’s rigorous standards for passenger inclusivity and safety.
Charging and Range: Meeting Real-World Demands
One of the most common concerns for taxi drivers is the practical range and charging infrastructure of electric vehicles. The LEVC TX addresses these by offering two core modes of operation:
What others are reading
- Pure electric mode: 78-mile range—ideal for city-only work, with zero exhaust emissions.
- Range-extender mode: Employs a petrol generator to supply electricity to the battery, extending total range to over 300 miles and removing the worry of running out of charge between fares.
The eCity platform, featuring a choice of charging speeds including rapid DC charging, allows drivers to recharge during regular downtime. Rapid charging to 80% can be achieved in less than an hour using high-powered chargers now increasingly available at taxi ranks, service stations, and public spaces throughout London.
Pioneers of Conversion: The Clipper Cab Project
While LEVC’s TX represents a ground-up new design, other innovators have turned their attention to retrofitting existing taxis. The Clipper Cab project, developed by Clipper Automotive, converts the classic TX4 diesel models into fully-electric cabs by swapping out the engine for a repurposed Nissan Leaf battery and motor.
- Zero emissions in use—fully electric drive, compliant with even the toughest urban clean-air zones.
- Reduced manufacturing carbon footprint—recycling donor vehicles and components, avoiding raw material waste.
- Preserved iconic design—the TX4’s silhouette and famed tight turning circle remain intact, maintaining both heritage and functionality.
- Approved for licensing in Oxford, Birmingham, Edinburgh, and elsewhere.
By upcycling and updating rather than scrapping older taxis, the Clipper Cab project demonstrates a win-win for cities and drivers: better local air quality, reduced vehicle noise, and lower operating costs—all with the reliability and familiarity cabbies and passengers have come to trust. Such projects highlight the innovation ecosystem rapidly growing around London’s black cab market, as environmental standards tighten and expectations shift.
Government Support and Incentives: Making the Switch Affordable
The UK government supports the electrification of taxis through targeted incentives, including:
- Plug-in Taxi Grant (PiTG): Grants of up to £4,000 (and previously up to £7,500) towards the purchase of new zero-emissions-capable cabs, extended through 2026.
- City-specific clean air regulations—such as London’s Ultra Low Emission Zone (ULEZ), driving demand for cleaner vehicles.
- Capital and local authority support—through infrastructure, education, and partnership with taxi operators.
These measures help offset the higher upfront cost of new electric cabs and encourage widespread adoption, accelerating the transition to sustainable urban transport.
Inside the Electric Cab: Passenger Experience and Modern Comforts
Stepping inside a plug-in black cab reveals thoughtful design that blends tradition with innovation:
- Spacious rear cabin accommodates up to six passengers, with ample space for luggage and mobility aids.
- Panoramic glass roof offers greater natural light and city views.
