The City of London Corporation has unveiled an electric version of its official 1973 Rolls‑Royce Phantom VI limousine, marking a visible step toward its goal of net‑zero emissions by 2027.
Conversion details and performance
Oxfordshire‑based Electrogenic handled the re‑engineering, swapping the V8 engine for a 120 kW electric motor paired with a 62 kWh battery pack. The battery occupies the space where the original engine sat, and a single‑speed direct‑drive transmission delivers 229 lb‑ft of torque to the rear wheels.
Range estimates place the vehicle at 100 to 120 miles per charge, enough for duties around the Square Mile and occasional trips beyond. Fast‑charging compatibility reaches up to 100 kW, and the battery could be doubled in size if longer distances become necessary.
Inside, a column‑mounted gear lever replaces the old automatic selector, and modern heating keeps the rear cabin comfortable. A special “Ceremonial” driving mode limits torque and softens throttle response, simplifying low‑speed maneuvering for processions.
Heritage preservation and future impact
Electrogenic’s work did not involve cutting, drilling, or welding the bodywork, meaning the conversion could theoretically be reversed, restoring the vehicle to its original condition. Only 374 examples of the Phantom VI were produced, making each unit a rare piece of automotive history.
“We were honoured to be asked to electrify this significant motor car, and to play a part in the City of London Corporation’s journey to net zero,” said Steve Drummond, CEO of Electrogenic. “When it was launched in the late 1960s, the Rolls‑Royce Phantom VI was the most refined and dignified limousine on the road. Now, thanks to electrification, its core character has been enhanced further. It is whisper quiet, effortless to drive with swift performance, and has zero tailpipe emissions.”
The Lady Mayor, Dame Susan Langley, added, “We were delighted to welcome the vehicle back following its transformation, marking an important step in modernising the mayoral ceremonial fleet while preserving the heritage and character of these iconic vehicles. The project demonstrated how historic assets can be responsibly adapted for the future, combining traditional craftsmanship with modern electric technology.”

For the city’s officials who rely on the limo for official engagements, the silent powertrain means less disruption during formal events, and the reduced emissions align with broader sustainability policies. The conversion also shows that preserving a vehicle’s aesthetic and cultural value does not have to conflict with modern environmental standards.
Public debut and next steps
The electric Phantom VI made its first appearance at this week’s Salon Prive concours held at Blenheim Palace. After the showcase, it will resume its ceremonial duties, traveling to meetings, state functions, and other official outings throughout London.
It will return to ceremonial duties soon.
Because the conversion avoided permanent structural changes, the car could be returned to its classic gasoline configuration if future preferences shift. This flexibility may encourage other institutions to consider similar retrofits for their heritage fleets.
Overall, the project illustrates a practical path for integrating historic vehicles into a low‑carbon future, offering a template that could be replicated by museums, clubs, and other civic bodies.
The corporation aims to have the entire mayoral fleet electrified by 2027, a milestone in its climate plan.
