Rolls-Royce Cullinan Overdose revealed

A souped-up Rolls-Royce Cullinan has broken cover in Germany.

Customisation company SPOFEC says the British luxury SUV is now even more exclusive thanks to a widebody kit featuring pumped out wheel-arches and huge 24-inch forged alloy Vossen wheels wrapped in 295/30 performance street tyres.

The modified Cullinan Overdose is a huge 120mm wider than the standard model, with a width of 2.12m at the rear axle, while the flares add 100mm to the front-end. It’s also lowered by 40mm, and SPOFEC says handling is more agile thanks to the lower centre of gravity.

Extra speed comes courtesy of an upgraded engine control unit (ECU), giving the Cullinan Overdose’s V12 engine special mapping for ignition and injection, as well as more boost pressure for the twin turbos.

That leads to a performance increase of around 84kW/160Nm – taking the thumping 6.7-litre engine’s outputs to an enormous 504kW of power and 1010Nm of torque. A new 0-100km/h acceleration time of just 4.9 seconds is also claimed.

Underneath the 2.7-tonne SUV, the regular version of which costs $695,000 drive-away in Australia, is a stainless steel sports exhaust with electronic sound management from inside the cabin.

On the outside, Rolls-Royce’s standard front bumper has been replaced with a SPOFEC front fascia that gives the Cullinan a “more distinctive face and reduces front-axle lift at high speeds”.

There are also ‘specially sculpted’ rocker panels running between the front and rear flares and a ‘subtle’ spoiler and diffuser at the rear.

Inside the cabin, SPOFEC says owners can request an endless variety of colours and trim materials.
