The City of London Corporation's official 1973 Rolls-Royce Phantom VI has been converted to battery-electric power by British specialist Electrogenic. The project was commissioned during the mayoralty of Alderwoman Dame Susan Langley, the 697th Lord Mayor of the City of London. The limousine is expected to continue carrying out ceremonial duties, but without its original combustion powertrain.
Preservation was central to the conversion. Electrogenic says the installation required no cutting, drilling or welding of the original structure, making the work fully reversible. That matters on a Phantom VI, a model produced in only 374 examples, and particularly on a car with an established civic role rather than an ordinary private ownership history.
A 62 kWh battery pack now sits under the long bonnet and feeds a 120 kW electric motor producing 310 Nm of torque. Electrogenic quotes a real-world range of 100 to 120 miles and support for up to 100 kW DC rapid charging. The company also says the car's size leaves scope for additional battery capacity in the future if its duty cycle ever demands more range.
The most distinctive software feature is a dedicated "Ceremonial" driving mode. It softens the response and limits power and torque so the Phantom can maintain the slow, stately pace required during civic processions. A normal mode is retained for ordinary urban use, including regenerative braking.
The conversion forms part of the City of London Corporation's plan to reach net-zero carbon emissions from its own operations by 2027. The electrified Phantom VI was displayed at Salon Privé at Blenheim Palace before returning to official service.
This is a restomod with a very different brief from the usual performance-led conversion. The objective was not to make a classic faster or turn it into a more practical private car. It was to keep a historically significant working vehicle in active ceremonial use while changing its source of propulsion and preserving the possibility of returning it to its previous mechanical state.
