Spofec, a Germany-based tuning shop specializing in bespoke Rolls-Royce vehicles, has unveiled its latest and greatest Cullinan-based project called Overdose. Aside from an aggressive aerodynamic kit, the opulent SUV gets a sizable power boost.

The aero package includes wheel arch extensions, side skirts, new bumpers on both ends, a rear diffuser, and a rear spoiler.


Straight from the factory, the Cullinan packs a V12 with 6.75 liters of displacement, 571 hp and 850 Nm of torque. Opting for the Black Badge Series raises the numbers to 600 hp and 900 Nm. The Spofec Overdose ups the ante once more with up to 685 hp and 1,010 Nm reaching the wheels.

From the technical side of things, the upgrade kit includes a sports-grade exhaust system, a new ECU, higher boost pressure, and reprogrammed ignition cards. Despite the added punch, the luxury SUV still sprints 0-100 km/h in the same 4.9 seconds as the Black Badge, and also maxes out at 250 km/h.
