Carrying more weight than the Wraith and producing modestly less power makes the Dawn slower than the coupé – 5.2sec to 60mph, compared with 4.6sec – but in reality the difference in all-out acceleration is about as meaningful as the relative difference in acceleration between the RMS Queen Mary and the RMS Queen Elizabeth.

Burying the solemnly long-travel accelerator into the extravagant carpet pile is hardly what the Dawn is about – despite the preparedness of the V12 to live up to the promise of its gargantuan output.

At a typical cruise, 93% of the Dawn’s horses are lying idle, apparently. How superbly extravagant!

Instead, the idea is to keep the car’s Power Reserve gauge (the dial Rolls uses in place of a rev counter) at just below 100% while all the time wafting along like your worldly cares are considerably loftier than the mundane scrabble to get somewhere at a specific time.

In this respect, the low-boost, big-displacement personality of the V12 makes it an ideal power source, as does the 575lb ft it quietly dispatches to the rear axle.

We found room to gripe about the programming of the eight-speed gearbox when it was deployed in the Ghost, but those concerns were ironed flat a generation ago. Now the ZF auto barely troubles itself with the idea of a lower cog, and if it does, you scarcely feel it anyway.

There is nothing as unsightly as paddles to ruin the ‘minimum effort’ ambience, and although it would very occasionally (twice a fortnight, perhaps) be nice to select your own moment to downshift, the kickdown is forceful should you trigger it.

The Dawn takes less than 2.0sec to dispatch all meaningful 20mph accelerative increments (20-40mph, 30-50mph, 40-60mph) and will take only a second longer to get from 30-70mph than a BMW M5
