A coachbuilt Bentley invites close attention to color, materials and detail. Big Boy Exotics offers nationwide US car sourcing for buyers who want to understand the engineering behind those choices as well. The Batur Convertible is a particularly revealing example: a planned series of just 16 customer cars supported by a substantial development program.
Bentley revealed the model on May 7, 2024 and announced its first completed production example on August 7, 2025. Those milestones frame this review. The interesting question is how a highly individual, very-low-volume convertible becomes a complete grand-touring car.
Small production, broad testing
An October 8, 2024 development update described more than 120 tests and more than 58 weeks of vehicle validation using two pre-series cars. The scope included durability, aerodynamics, noise, vibration, sunlight simulation and high-speed stability. Even the finish of the ventilation controls formed part of the assessment.
That last detail is easy to underestimate. In a bespoke cabin, a material has to do more than look compelling under showroom lighting. It meets fingertips, changing temperatures and sunlight. Different surfaces also sit next to one another, making consistency in color, texture and fit part of the engineering problem.
The broader lesson is that individuality creates work rather than removing it. A finish that suits one commission must still function as part of the car. The unusual material is only successful if its visual promise survives the environment in which the owner will use it.
A roof connects several disciplines
The Batur Convertible has two seats and a retractable fabric roof. Bentley's launch material quotes a 19-second opening or closing cycle at speeds up to 30 mph. It also describes insulation, sealing and acoustic treatment intended to make the closed cabin feel appropriately refined.

For a grand tourer, the roof changes much more than the silhouette. It influences wind noise, weather protection, visibility and the sense of enclosure. The transition from open to closed also has to coexist with trim, moving hardware and luggage space. These are the practical details that make a convertible useful across an entire day.
Behind the seats, the sculpted airbridge and tapered cowls help define a semi-enclosed luggage area. That is an unusually clear example of a styling theme doing a second job. The form gives the cabin its two-seat identity while establishing a particular way of carrying belongings.
The W12 provides the mechanical context
Bentley's first-production announcement identifies a hand-assembled, twin-turbocharged 6.0-liter W12 producing 740 bhp. The engine connects this coachbuilt series with an important chapter of modern Bentley history. It also distinguishes its ownership proposition from the fourth-generation Continental GT's electrified direction.
Our Continental GT Speed hybrid ownership guide explores that newer architecture. A buyer considering both should think about the experience desired from the powertrain and body style, then consider rarity and personalization alongside those requirements.
On a previously commissioned car, individuality also makes records valuable. Original specification documents can explain finishes and accessories that might otherwise appear unfamiliar. They provide a reference for future care and help separate an intentional design decision from a later alteration. This is especially important when a replacement part would need to match a very specific material or finish.
The Batur Convertible's appeal emerges from that combination: an intimate open cabin, a distinctive engine and extensive attention to how bespoke details function. The small production number is only the beginning of its story.
