The Rolls-Royce Cullinan is already one of, if not the most luxurious SUV in the world, but that hasn't stopped German tuner Spofect (a business division of Novitec that specializes in tuning Rolls-Royce models) from making the SUV even more special by enhancing the exterior, boosting the power, and improving the driving dynamics.

A custom widebody kit adds new aerodynamic components that give the opulent SUV an even more striking and less restrained appearance, including a new front bumper reduces front-axle lift at high speeds in addition, while the already-massive SUV is 4.72 inches wider at the back and 3.9 inches wider at the front thanks to flared fenders housing huge 24-inch wheels wrapped in high-performance street tires.

Compared to the standard model, the tuned Cullinan rides around 1.5 inches closer to the ground, thanks to a control module. The lower center of gravity also makes the handling more agile. Elsewhere, new rocker panels give the Cullinan a lower and sleeker stance, while a subtle rear spoiler and diffuser give the luxury SUV a sportier appearance.

To complement the sporty looks, Spofec has extracted more performance from the Cullinan's 6.7-liter twelve-cylinder engine by adapting an electronic plug-and-play control module to the ECU along with special mapping for fuel injection and raising the boost pressure.

These modifications increase the output by 114 horsepower up to 685 horsepower and 744 lb-ft of torque. 0-62 mph now takes just 4.9 seconds, which is impressive considering that the Cullinan weighs 2.7 tons. Top speed remains electronically limited to 155 mph. Spofec also offers a stainless steel exhaust system, while an actively controlled exhaust flap features an electronic sound management that can remotely adjust the exhaust note to sound subtle or sporty.

Inside, the Rolls-Royce Cullinan's cabin offers unrivaled luxury, but Spofec also offering a range of interior customization options including a huge variety of colors and a large range of leather and Alcantara materials.
