It is not necessary to say that the Mulliner Batur with a soft top would present the same engine as the regular car – or the most powerful W12 any Bentley has ever had. The 18 vehicles that were sold have 545 kW (731 hp) and 1,000 Nm (737.6 pound-feet). This is probably the last configuration this engine will ever present before emission regulations make it kick the bucket. Future Bentleys should be hybrid or powered solely by batteries.
Exclusive vehicles such as the Mulliner Batur never face depreciation issues if they get other derivatives. Anyway, Bentley could also call the convertible something else entirely, making it look like an independent model. That would work to ensure wealthy buyers that they will still have something very unique.
We do not doubt the same people who bought the Mulliner Batur would buy its convertible units, whatever Bentley decides to call them and regardless of what the British brand wanted to charge them. If they don’t, other people with deep pockets should already be in line for the privilege of being invited to spend £2 million on a machine only they know about.
