Reliability Verdict
Both models share the N74 engine with identical VANOS and HPFP risk profiles. The Ghost wins on lower ownership cost: lighter weight means slower brake and tire consumption, less suspension stress, and smaller annual service bills. The Cullinan costs 30-50% more per year to run than the Ghost on a per-mile basis.

Rolls-Royce Ghost vs Cullinan: The Ownership Cost Verdict
Both the Rolls-Royce Ghost and the Rolls-Royce Cullinan are powered by the same N74 6.75-liter V12. Both offer the same standard of luxury. Both are serviced by the same specialist network.
But they are not equally expensive to own —nd the gap is larger than most buyers expect.
1. The Shared Foundation: N74 V12
Both cars use the same engine. This means:
- Identical VANOS risk at 60,000—00,000 miles
- Identical HPFP failure profile at 60,000—0,000 miles
- Identical sensitivity to oil change intervals
- Identical cooling system architecture
For a complete engine breakdown, see the N74 V12 Engine Reliability Guide.
The engine is not the differentiator. Weight and duty cycle are.
2. The Weight Gap: A 900kg Difference
| Specification | Ghost | Cullinan |
|---|---|---|
| Curb Weight | ~2,490 kg (5,490 lbs) | ~2,660 kg (5,860 lbs) |
| Body Style | Saloon | SUV |
| Ride Height | Low | High (air suspension fully loaded) |
| AWD System | Optional | Standard |
That 900kg difference flows through every consumable system on the car.
3. Brake Cost Comparison
| Item | Ghost | Cullinan |
|---|---|---|
| Front rotor life (city use) | 15,000 —22,000 miles | 8,000 —15,000 miles |
| Annual brake cost (city use) | $1,500 —2,500 | $3,000 —5,000 |
| Annual brake cost (highway) | $800 —1,500 | $1,500 —2,500 |
Over 5 years of city use, the Cullinan costs $7,500—12,500 more in brake costs alone.
4. Air Suspension Comparison
Both models ride on air suspension. The Cullinan’s system works harder:
| Item | Ghost | Cullinan |
|---|---|---|
| Air strut typical life | 7 —9 years | 5 —7 years |
| Full system replacement cost | $3,500 —6,000 | $5,000 —8,000 |
5. Tire Consumption
The Cullinan uses wider, heavier-duty tires on a heavier platform:
| Item | Ghost | Cullinan |
|---|---|---|
| Tire set cost | $2,000 —3,500 | $3,000 —5,000 |
| Tire life | Standard | 15—5% shorter |
6. Direct Annual Cost Comparison
| Annual Item | Ghost | Cullinan |
|---|---|---|
| Service | $2,500 —4,000 | $3,000 —5,000 |
| Tires | $2,000 —3,500 | $3,000 —5,000 |
| Brakes | $1,500 —2,500 | $3,000 —5,000 |
| Air suspension reserve | $1,000 —1,500 | $1,500 —2,500 |
| Engine reserve | $1,000 —2,000 | $1,000 —2,000 |
| Total Annual | $8,000 —13,500 | $11,500 —19,500 |
The Ghost is cheaper to operate by $3,000—6,000 per year in equivalent use conditions.
7. The Verdict
Choose the Ghost if: Cost of ownership is a consideration. You want the Rolls-Royce experience with the lowest possible running costs. You drive primarily on smooth roads or highways.
Choose the Cullinan if: The SUV form factor is a genuine requirement. You have children or need the practicality. Budget can absorb an additional $3,000—6,000 per year in running costs without impact.
Both require: Strict oil service intervals (7,500 miles maximum), pre-purchase inspection by an N74 specialist, and a budget that includes VANOS and HPFP service in the 60,000—00,000 mile window.

Executive Buying Advice
If cost of ownership is a factor, choose the Ghost. If the SUV form factor is essential, buy the Cullinan but budget $3,000—5,000 more per year versus the Ghost, and inspect the air suspension rigorously before purchase.
