The Architecture of Luxury really comes into its own in creating Cullinan. The engineering team behind Cullinan adapted the Architecture of Luxury to the design template of a high-bodied car laid down by Giles Taylor and his design team thanks to its innate adaptability. It was designed and engineered from the ground up in such a way as to be scalable to the size and weight requirements of different future Rolls-Royce models, including those with different propulsion, traction and control systems, thus underpinning the long-term future product roadmap. Cullinan uses this new architecture in a wholly different manner to deliver an iconic design and presence, uncompromised comfort, space and usability, cutting edge technology and the peerless on-road and off-road driving experience and capability. The component parts of the base architecture were reconfigured into a spaceframe that was higher and shorter whilst also delivering a completely new feature never seen before on a series production Rolls-Royce – a tailgate. The all-new aluminium sub-structure delivers extraordinary car body stiffness for exceptional 'best-in-class' functional performance on rough terrain whilst offering better ride comfort. The ‘Magic Carpet Ride’ taken off-road The integration of new technologies into the architecture was also key to ensuring the fundamental quality of Cullinan as Effortless, Everywhere. The engineering team began by creating a drivetrain that would bring Rolls-Royce’s famous ‘Magic Carpet Ride’ off-road. “The drivetrain system we engineered for Cullinan had one key job to do,” explains Caroline Krismer, Engineering Project Leader for Cullinan. “To bring the famed Rolls-Royce ‘Magic Carpet Ride’ to all other terrains possible, while ensuring class- leading on-road behaviour in the SUV sector.” Rolls-Royce’s celebrated Magic Carpet Ride impresses off-road as well as on-road thanks to the new lighter architecture, and the latest generation of self-levelling air suspension. Through a thorough re-engineering of the existing air suspension system – including adding larger air struts with more air volume to cushion the blows of the toughest of terrains – the strengthening of drive and prop shafts, the inclusion of drive to the front wheels as well as the back for the first time in Rolls-Royce history, and the complete reworking of the new 6.75 litre twin-turbo V12 Rolls-Royce engine to deliver just the right level of torque (850Nm) at the lowest possible revolutions (1,600rpm), the Rolls-Royce engineering team has ensured Cullinan will take owners to places no modern Rolls-Royce owner has travelled in luxury before. The suspension makes millions of calculations every second as it continuously varies the electronically controlled shock absorber adjustment system – reacting to body and wheel acceleration, steering inputs and camera information. A new double-wishbone front axle and 5-link rear axle deliver astounding levels of control over lateral roll and shear forces and deliver incredible agility and stability, as does the addition of four-wheel steering, all contributing to incredible drivability and nimbleness. In the case of driving off-road, the electronically controlled shock absorber adjustment system uses an air compression system to actively push down any wheel it detects losing traction to ensure every wheel is constantly in contact with the ground and maximum torque is being provided to all wheels. “Put simply, what makes the car great on-road makes the car great off-road,” concludes Krismer. The final piece of the puzzle of ensuring that the Rolls-Royce Cullinan is Effortless, Everywhere is one single button. Known within Rolls-Royce as the ‘Everywhere’ button, one single push is all it takes to harness all the aforementioned peerless Rolls-Royce engineering and unleash all of Cullinan’s off-road capability.
