Rolls-Royce's Cullinan SUV is about to receive its first major update since arriving for the 2019 model year.

A thinly veiled prototype for the updated Cullinan, which may be called the Cullinan Series II, has been spotted, revealing a number of the styling changes planned.

The front fascia has been completely renewed, with its lower section exposed on the prototypes. Other parts are hidden by gray camouflage gear.

The internals of the headlights are also a new design, and the signature pantheon grille has also been renewed with a design featuring a horizontal line separating the vertical slats from the top of the grille.

At the rear, the new design of the lower fascia was left unmasked. The square finishers for the exhaust tips are also a new design. They've been made bigger than the finishers used on the current model.

It isn't clear what updates are planned for the interior. It also isn't clear whether there will be any updates to the mechanical components, though Rolls-Royce doesn't typically make major mechanical changes when it updates a model.

The Cullinan is based on a high-riding version of the aluminum spaceframe chassis that underpins all current Rolls-Royce models. It's powered by a twin-turbocharged 6.75-liter V-12 generating a peak of 563 hp.

Look for the updated Cullinan to launch in 2024 as a 2025 model for the U.S.
