Rolls-Royce Cullinan uses ZF's 8AT transmission. The functions of the transmission are: 1. Change the transmission ratio; 2. Expand the torque and speed of the driving wheels; 3. Enable the car to reverse; 4. Facilitate gear shifting or power output. The Rolls-Royce Cullinan is an SUV under Rolls-Royce. The car has a length, width, and height of 5341mm, 2164mm, and 1836mm respectively, with a wheelbase of 3295mm. In terms of power, the Cullinan is equipped with a 6.7-liter twin-turbocharged V12 engine, with a maximum power of 420 kilowatts, a maximum torque of 850 Newton-meters, a maximum power speed of 5000 revolutions per minute, and a maximum torque speed of 1600 revolutions per minute.

I've driven luxury cars for over a decade, and the Cullinan's transmission is truly top-tier, equipped with a ZF 8-speed automatic. This thing shifts silently, and when you floor it, it can instantly drop from 8th to 3rd gear—the acceleration kicks in immediately. Rolls-Royce specifically tuned it, so starting off feels like being pushed forward by velvet, with absolutely no jerking. This transmission also features adaptive learning; after just two weeks, it figures out your throttle habits. That said, the Cullinan's V12 engine has quite a temper—if it weren't for this transmission keeping it in check, the ride wouldn't be this smooth. Luxury cars are all about that seamless, effortless harmony.

A friend in automotive R&D told me that the Cullinan uses the same ZF 8HP transmission commonly found in BMW models, but Rolls-Royce has modified 70% of its components. The most impressive part is its torque converter, which utilizes aerospace-grade sealing materials, making it maintenance-free for life. While you might not notice much difference in daily driving, I once tested it on a continuous uphill stretch—even at 4,000 RPM, the transmission's lock-up mechanism remained rock-solid. This precision tuning reduces fuel consumption by 1.8L per 100km compared to the older 7AT, a remarkable feat for a V12 engine. Though many only recognize Rolls-Royce for its hand-stitched leather, the real value lies in these cutting-edge technologies hidden beneath the chassis.

Last time I accompanied my boss to pick up the Cullinan, the sales director kept me for half an hour talking about the transmission. This car uses an 8-speed automatic transmission with satellite navigation linkage function, which automatically downshifts and supplements torque before cornering. The most surprising part was the off-road mode - when engaged, the transmission allows starting in 2nd gear, enabling stable hill climbing even when tires slip on snow. I heard Rolls-Royce's testing team specifically conducted three months of extreme cold testing in Alaska at -40°C to ensure the plastic paddle shifters wouldn't crack from freezing. But honestly, who actually goes off-roading with this car? Yet the brand spares no expense on these details - perhaps this is the confidence that comes with a 3 million RMB price tag.
