Novitec Turns Rolls-Royce Cullinan Into 697-HP Widebody Beast originally appeared on Autoblog.
It’s as powerful as an Aston Martin DBX707
Novitec is a German tuner that’s known for specializing in upgrades for Italian automakers like Ferrari and Alfa Romeo. The Bavaria-based company also has a separate division called Spofec, which specifically tunes Rolls-Royce models, and it’s this division that’s responsible for a particularly mean interpretation of the Cullinan ultra-luxury SUV.
Spofec’s Overdose widebody kit is based on the facelifted version of the Cullinan, which was introduced for the 2025 model year—a controversial facelift that other tuners have tried to fix. Besides giving the SUV a more muscular stance, it’s also given the already powerful V12 more grunt.
Seriously Large Wheels, But Other Touches Are More Subtle

The most obvious change to this Cullinan Series II are custom 24-inch wheels, developed in collaboration with American manufacturer Vossen. The polished wheels with their spatially offset spokes will be a nightmare to clean, so it’s just as well that very few Rolls owners clean their own cars. Customers can choose from 48 wheel colors with a brushed or polished finish. The Overdose kit also includes fender flares that add 4.7 inches to the SUV’s width, giving it even more presence.
Unlike Mansory’s more garish Rolls-Royce Dawn, Spofec took a more reserved approach to the rest of this Cullinan. The Spofec front fascia isn’t dramatically different from the standard model’s, but it does get LED position markers in place of the stock bumper. The surrounds for the side air intakes are fashioned from carbon, and other additions include a subtle rear spoiler, a diffuser made from visual carbon, and tailpipe tips integrated into the diffuser.
A single stripe runs along the sides of the body below the glasshouse, and the SUV has been slightly lowered.
Even More Power For The V12

Whereas the normal Rolls-Royce Cullinan produces 563 horsepower from its 6.7-liter twin-turbo V12, the Black Badge version—as seen here—makes 592 hp. That still wasn’t enough for Spofec, which tuned the V12 to deliver 697 hp and 782 lb-ft of torque; that’s exactly as much power as you get in the Aston Martin DBX707, a much more performance-focused SUV than the Cullinan. Spofec claims a 0-62 mph (0-100 km/h) time of 4.6 seconds, which is quick but as as ferocious as the new Bentley Bentayga Speed.
A performance, flap-activated exhaust allows customers to fully unleash the sound of the V12, which you can hear in the video below.
Very little was said about the interior, with Spofec only saying it will happily cater to each client’s individual wishes. A single image of the rear seat—the most important part of any Rolls-Royce cabin—was shared by the tuner. It has black leather and vivid orange accenting on the seats and door panels. Rolls-Royce’s gorgeous Starlight Headliner is still the most atmospheric roof design you’ll find in almost any luxury car.
Overall, Spofec’s Cullinan makeover is far from the wildest body kit we’ve seen. It won’t be for everyone, but the tuner has shown just enough restraint here for a vehicle as prestigious as the Rolls SUV.
