Identical to that of other Rolls-Royce Phantoms, the 6.75-litre V12 engine makes a solid 453bhp and a not-insubstantial 531lb ft of torque, driving through a six-speed automatic transmission. That sounds sufficient for plenty of performance – but maybe 'performance' is too vulgar a word for such a monumental car. ‘Propulsion’ is perhaps more fitting.
Nevertheless, quantify and rate its performance we must. So here are the figures: 0-60mph in 6.1sec and 100mph in 15.7sec. How does this feel in a car weighing 2655kg? At first, frankly ridiculous. So majestic does the Phantom feel at pedestrian speeds that when the moment comes to extend the throttle fully, the vigorous, if still entirely dignified, progress comes as some surprise. With familiarity, though, comes the realisation that the Coupé’s pace is more brisk than truly rapid. In fact, our figures trail Rolls-Royce’s claims for the car (by 0.5sec for 0-60mph) and those we achieved for the saloon in 2003, a consequence, perhaps, of the Coupé’s additional 70kg.
But does the Phantom have enough performance? In almost all circumstances, yes; only on prolonged high-speed ascents would more power help. That is something BMW could almost certainly provide, but perhaps not without damaging the one element that defines Rolls-Royce more than any other: the sense of achieving without ever really trying. The 6.75 V12 never sounds strained, there is no hint of vibration or stress, just a gentle, distant and refined hum as the 531lb ft of torque goes to work.
