Fitment Details
xBentley Bentayga W12 Technical Fitment
| Bentley Model | Year Range | Engine Type / Fitment Notes |
|---|---|---|
| Bentley Bentayga (W12 Petrol) | 2016 – 2020 | 6.0L Twin-Turbo W12 Petrol – High-output engine architecture |
| Bentley Bentayga (W12 Variant) | 2017 – 2020 | Rear Centre Gearbox Mounting – Specialized anti-vibration transmission support |
Technician’s Advisory: The rear centre gearbox mount is a load-bearing rubber-to-metal bonded component. Over time, the rubber can sag or tear due to the sheer torque of the W12 engine. Symptoms of a failing mount include a "thud" during gear engagement or increased drivetrain vibration felt through the center console. Always inspect the transmission subframe bolts for proper torque when replacing the mount.
