The Rolls-Royce Motor Cars Director of Design Giles Taylor explains in an interview on YouTube the car model naming decision of the Wraith that is shown today at the Geneva Motor Show. According to him the reason the name Wraith suits the new car model so well is “this sense of fleeting – the fleeting spirit, slightly ethereal, slightly enigmatic”. I should include the official meaning of the word wraith (according to the Oxford Dictionary):
a ghost or ghostlike image of someone, especially one seen shortly before or after their death.
