6.0L W12 Twin-Turbo
Petrol
Test drive task: Perform a sharp, low-speed steering maneuver in a quiet parking lot. | Description: Listen carefully for any clonking or knocking sounds from the front end, as the complex suspension control arm bushings can eventually show signs of wear in a vehicle of this weight.
Test drive task: Accelerate briskly on an open road where safe to do so. | Description: Observe the gear shifts for any hesitancy; the ZF 6-speed transmission is robust, but ensuring smooth transitions through all gears is a sensible step to confirm the transmission fluid has been managed appropriately.
Test drive task: Cycle through the infotainment and seat adjustment settings. | Description: Electronic gremlins are not uncommon in luxury grand tourers of this era; checking that every motorized comfort feature works as intended is a smart way to gauge the health of the electrical systems.
Test drive task: Once the engine is fully warmed up, monitor the cooling fans and temperature gauge. | Description: The W12 engine creates a significant amount of heat; ensuring the cooling system is efficient is vital, so check that the temperature needle stays stable and the fans engage correctly when idling.
Usually marks the point where initial suspension components and preventative cooling system checks become standard practice.
Often the stage where comprehensive engine bay inspections and drivetrain fluid flushes are highly recommended for continued longevity.
A point where long-term ownership planning often involves reviewing the auxiliary systems and turbocharger health.
Check that the full service history is documented, ideally by a specialist familiar with the W12 platform.
Verify the condition of the tyres to ensure they are high-quality, matched sets, which is crucial for handling the power.
Inspect the brake discs and pads for uneven wear, as these are significant components on a vehicle of this size.
Confirm that the battery health is optimal, as these cars are quite sensitive to low voltage levels.
Review the recent maintenance records to see if the cooling system hoses and thermostat have been checked recently.
Estimated repair costs if issues arise
While these units are engineered for longevity, they can eventually develop leaks over time. It is helpful to keep a reserve fund if the vehicle shows any signs of sitting unevenly after being parked.
Accessing the rear of the W12 engine is quite an involved process. If you experience a slight misfire, it is wise to budget for a complete set replacement to ensure smooth operation.
Over many years, the heat from the engine bay can make rubber vacuum lines brittle. Replacing these is a common preventative task to ensure the twin-turbos operate at peak efficiency.
