SPOFEC transforms the Rolls-Royce Cullinan Series I into a more powerful, extravagant, and performance-oriented luxury SUV. The OVERDOSE S widebody conversion enhances its commanding presence from every angle, while accommodating the expanded stance with precision-engineered design.

Available for both standard and Black Badge models, the refined body components integrate seamlessly with SPOFEC SP3 24-inch forged wheels developed in collaboration with Vossen to perfectly fill the widened arches and elevate road presence. A twin-turbo V12 upgraded to 707 horsepower and 1,060 Nm of torque delivers exceptional performance, complemented by SPOFEC sports exhaust systems with optional electronic sound management. Lowered suspension tuning sharpens agility, while bespoke refinement options complete the exclusive transformation by the NOVITEC Group’s Rolls-Royce specialist division.
