The BMW Group's luxury car maker recently revealed that the model's all-new aluminium architecture is in its advanced development stage.
The production headlights of the Rolls-Royce flagship are visible through the disguised car pictured here and appear to be slimmer than those of the current car. A design similar to that of the headlights on the Rolls-Royce Ghost, with a step in the lower edge of the light making way for the indicator strip, appears to have been chosen.
A full-width grille with a design extending into the bumper is also revealed. Aside from these differences, a similar design to that of the previous car is suggested.
Rolls-Royce recently released a new picture of the 2018 car's structure. Earlier images shown in our gallery are of development mules being subjected to cold-weather testing.
Two prototypes of the next-generation Rolls-Royce Phantom were also spied, including a long-wheelbase variant.
The cars were heavily disguised but we what looks like a slightly longer body can be seen, as well as a new front bumper design featuring wider air vents that extend further out towards the car’s sides.
The Spirit of Ecstasy is also missing, although this is likely to be because the car is a test mule.
At the rear, the bumper appears to protrude less than that of the current Phantom, with a more flush design from the boot lid to the rear bumper. There are also more rounded tail-lights, but these are temporary units rather than final production parts.
No technical details have been revealed, but insiders expect the new car to feature one of two possible engines: a more powerful version of the current Phantom’s 6.75-litre V12 unit, or a boosted version of the 6.6-litre V12 unit featured in the new Dawn.
Rolls-Royce says demand for the current Phantom is so high that orders have pushed into 2017. The car maker also says that all 50 of the final Phantom Coupé and Drophead Coupé Zenith Collection cars have been sold.
