The car is so nuts that it’ll never make it to production in its current form. But that doesn’t make it any less interesting.

Rolls’s Vision Next 100 — a nearly 20-foot-long, five-foot-tall, fully autonomous coupe with the physical presence of a super yacht — is meant to embody the brand’s goals for the next 100 years.

It comes at the end of production of the seventh-generation Phantom and is part of a series of concept vehicles BMW Group developed to celebrate its centenary in 2016 and herald its next century of design and technology.

The company unveiled the BMW Vision Next 100 in Munich last March and a MINI concept earlier this month.

“With the Rolls-Royce Vision Next 100, we were mindful not to dwell on the past,” said Giles Taylor, Rolls-Royce’s director of design. “We wanted to be as innovative as possible and at the same time transcend the design history of the marque.”

Taylor said the key to the car is that it rejects the notion that future modes of transport will be anonymous, utilitarian, and bland. Is that shade thrown at other self-driving cars (Google, ahem) that look about as interesting as a slim white landline telephone? Probably.

At any rate, the Rolls Vision Next 100 looks like an intergalactic chariot, with the historic Spirit of Ecstasy on the hood, the Pantheon grille, and a long Rolls hood. The car is encased with a glass fastback canopy roof and a “Crystal Water” lower surface exterior material that is made to make the car look as if it were floating.

It has the same dimensions as the modern Phantom Extended Wheelbase, and the oversize Spirit of Ecstasy hood ornament is based on ones from the 1920s-era Phantom. The luggage compartment in the rear comes with two bespoke “Grand Tourer” cases.

The Vision Next 100 will be powered by a zero-emissions powertrain placed on an “advanced suspension,” though a spokesman for Rolls declined to elaborate on what form the engine will take. (Will it be electric? Nitrogen? Magnetic fields? I’m not sure even Rolls knows for sure.)

What Rolls did claim is that future luxury buyers will commission their own coach-built concepts: Every Rolls-Royce will be a “unique, bespoke masterpiece” that elicits an emotional attachment between car and owner, a statement from the brand said.

Presumably that means if you buy a Rolls-Royce like this one, you can choose the furniture and trimmings inside yourself, if you don’t like the sofa inside this one.

Oh yes, the sofa: The inside of the Vision Next 100 is arranged like a lounge, with a clamshell canopy that encloses it with the silence of a prohibition-era bank bunker. And every lounge needs a small couch. This small one is wrapped in silk and backlit so it looks as though it floats in its place. The rest of the cabin is surrounded by Macassar wood and cosseted with a deep-pile ivory wool carpet.

The car is controlled by an interactive programme called ‘Eleanor’, so named after the muse to the artist Charles Sykes who sculpted the original Sprit of Ecstasy that became the Rolls icon more than 100 years ago.

The programme works as a chauffeur and assistant, like an automotive version of the iPhone’s Siri programme that reminds passengers (or guests, as Rolls likes to say) about appointments and tasks and makes suggestions to ease anticipated impediments to plans.

“She brings the car around when her passengers are ready to travel and, whilst conveying her charges to their next destination, helpfully but discreetly makes suggestions and recommendations, briefing them ahead of their arrival so they are ready to perform,” Rolls said.

No word yet on whether this voice can be programmed to assume a man’s name and tone; I’m sure I’m not alone in wishing that all these hardworking female virtual assistants (Alexa, Siri, Eleanor) could be repurposed with male attributes. But that’s a topic for another day.

Of course, the key to ultimate luxury, according to Rolls-Royce, is the grand arrival, a phenomenon it spent three long paragraphs explaining in press notes as it pertains to the Vision Next 100.

Basically the car starts to glow from the grille to the wheels as you pull up, and the top glass canopy lifts automatically to allow you to fully stand up before the coach door sweeps open and you alight. A red light also shines from underneath the car to provide a red-carpet feel as you step outside.

“Thus, as in Botticelli’s The Birth of Venus, our guest is framed and ready to step gracefully into the limelight and greet [her] audience,” the statement from Rolls said.

It’s a lot. Then again, no one ever bought a Rolls-Royce to stay incognito.
