Key to the creation of the Rolls-Royce Cullinan SUV was the Architecture of Luxury – Rolls-Royce’s proprietary all-aluminium architecture. The integration of new technologies into the architecture was 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.
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.
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.
Once engaged, the driver can finesse the off-road setting to glide over any situation, whether it be rough track, gravel, wet grass, mud, snow or sand delivering all 850Nm of torque to all four wheels without interruption. And faced with deep snow, sand or the need to ford streams, Cullinan delivers the deepest wading depth of any super-luxury SUV at 540mm thanks to its highest ride height.
