Bentley Mulliner has just finished building Batur Convertible #4, another coachbuilt model that has been created as the result of a comprehensive client co-creation process. The model has been ordered by Sonia Breslow, a seasoned Bentley collector, with a sophisticated specification developed over time based on her personal preferences for exterior colours, interior material selections, as well as one-off features. This model marks the first time these features appear within the Batur project range.
How does the new exterior specification differ from previous Batur Convertibles?
Batur Convertible #4 is completed in a three-tone exterior paint scheme in colours commissioned by the client. This is the first time a Batur has adopted a three-colour layout dictated by customer-supplied colours. A 6 mm gloss silver fine line discretely traces the lengthy bonnet profile of the vehicle.
Another first for the model is a fully colour-matched convertible roof. The canvas roof is finished in “Breslow Blue,” matched to the upper exterior paint, and when retracted, it reveals an Airbridge element finished in the same tone. Additional exterior details include a contrasting bonnet pinstripe, colour-matched accents on the wheels and wing mirrors, polished titanium exhaust finishers, and bright silver grille treatments.
What are the tailor-made features of cabin design?
The interior design is focused more on coordinated colour transitions versus the contrast-heavy styling. Warm tan and caramel tones are complemented by light blue accents that visually reference the colour scheme from the exterior. Stitching details cascade across continuously on the tonneau cover to the seats, headrests, and instrument panel.
Such subtle design cues are found throughout the cabin, from floor mats with incorporates the forms of Mount Batur, the name-giving landmark for this model, as these do not change the cabin layout architecture of the Batur model.
How has Personalisation been implemented for lighting and interaction?
Perhaps the most personalised element seen on the Batur Convertible #4 is the welcoming animation lamp. Created per the client’s design parameters, the animation involves the projection of the owner’s handwritten name using over 415,000 micro-mirrors. This is the first Bentley that incorporates a fully personalised welcoming animation on a car designed by a client for a Batur.
“This attribute is an expression of Mulliner’s capability to incorporate personalisation not only into physical materials, but also into digital and lighting components which influence user interaction with the car.
Which new materials and technologies are brought in?
Batur Convertible #4 marks the first time that three-dimensionally printed platinum appears in a Bentley car. The platinum is utilised in small but notable areas, such as the mark of the top dead centre on the wheel and the controls of the organ stops in the cabin. The adoption of platinum shows how additive manufacturing is being incorporated into low volume manufacturing in the automotive world.
Other handcrafted metalwork features include engine spin aluminium finish strip work on the fascia, playing homage to older Bentley models’ cabin designs. The Bentley Rotating Display features customised colour dial backgrounds and satin blue clock dial faces.
Which powertrain is preserved in the Batur Convertible?
Despite its unique configuration, Batur Convertible #4 retains its traditional mechanical setup like all other Baturs. With that being said, it features a W12 twin-turbocharged mill with a capacity of 6.0 litres and a combined crank and camshaft architecture that features a mere 2 bolts. The result is an impressive 740 bhp of power that propels this W12 as the most powerful road-going W12 Bentley yet.
Pricing, availability, and production context
The price for Batur Convertible #4 has yet to be revealed by Bentley as the details are greatly varying based on the client commission. The Batur Convertible comes from a heavily limited production series from the Mulliner coachbuilt programme, in which each of the cars has been built with a personalised specification after a lengthy consultation with the selected buyer. The customer delivery has been scheduled one after the other with no further production slots revealed.
