Designed to bring out the discreet power of the Phantom, the exterior of the 101EX featured a streamlined, reclined grille, flowing back into the aluminium bonnet and windscreen surround. The body was made of a unique carbon-fibre composite over the production Rolls-Royce aluminium frame, while the roofline is lowered in comparison to the original Phantom. The interior was designed to protect and cosset, and the high waistline emphasises the cocoon-like nature of the cabin. It features an intimate curved sofa in the rear, and introduced the Starlight headliner fibre optics, which are controlled by a dimmer. Meanwhile, the machined aluminium of the interior mirrors the solid hewn pieces used in the door handles and the oval exhaust pipes.
