Rolls-Royce recently created what could be the ultimate “ghost” squad car at a police department open house in the southern England city of Chichester.

Rolls took an example of its Ghost sedan done up in Black Badge trim, added some flashy lights and the blue-and-yellow Battenburg markings that distinguish cop cars throughout the United Kingdom, and trotted it out to the Chichester open house as part of a Rolls-Royce fundraiser for a children’s hospice serving the County of Sussex.

What’s too bad is the Rolls cruiser was all for show: after the open house, Rolls-Royce removed the decals and lights from the Black Badge-trimmed car, returning it to its original Andalusian White splendour.

As novel a project as this was, a big, fast sedan like the Ghost would hardly be out of place among other cop cars in the UK, never mind the world: Police in Avon and Somerset, headquartered near Bristol, added an Ariel Atom to their fleet a few years ago to help promote safe motorcycling.

Elsewhere in Europe, Italian police are renowned for employing some of the continent’s quickest performance cars to patrol the autostrada, including the 500-plus-hp Alfa Romeo Giulia QV; and the Lotus Evora, which they use to transport human blood and organs in a refrigerated compartment.

And if we’re going to discuss cool cop cars, Dubai merits more than a mention. The police there drive vehicles including a McLaren MP4-12C, Nissan GT-R, and Bugatti Veyron.

Back to Rolls-Royce’s Chichester show-and-shine: the Ghost Black Badge is the kind of massive sedan we expect from the storied British marque, powered by a 6.6-litre twin-turbo V12 cranking out 603 hp and 620 lb-ft of torque and a black-and-tan leather interior so nice it might actually cause an increase in crime.
