Luxury Car Curation:
The Bespoke Mastery of Bentley’s Batur Convertible #4
In the world of ultra-luxury, the ultimate status symbol is no longer just ownership; it is the Art of Curation. This philosophy is perfectly embodied by visionary client Sonia Breslow and her latest masterpiece: the Batur Convertible #4. As a “forever car” meticulously designed to remain in a private collection for a lifetime, this specific commission represents the most luxurious collaboration to date with Bentley’s bespoke division, Mulliner. Through a sophisticated co-creation process, the Batur #4 transcends traditional automotive design, blending world-first materials like 3D-printed platinum with a deeply personal aesthetic to redefine what luxury car curation truly means in 2026
- Batur Convertible #4 demonstrates four new possibilities through co-creation with a visionary client:
First tri-tone scheme using the customer’s own colours, including fine line emphasising endless bonnet styling
First colour-matched bespoke roof colour
First client-designed animated welcome lamp
First application of three-dimensional printed platinum crafted by Bentley
- The specification of car #4 represents the most luxurious commission to date with Mulliner Coachbuilt
- The client co-creation process demonstrates the breadth of techniques, colours, materials, and finishes that are available through Bentley’s bespoke Mulliner division
The most highly curated Batur Convertible so far has been completed by Bentley’s bespoke division, Mulliner. The art of creating a coachbuilt Bentley has become a repeat experience for the car’s new owner, with Batur. The client—Sonia Breslow—carefully specifies every last detail of her commissions, with an emphasis on beautiful cohesion across colors and materials.
Not only is there an art to producing a luxurious curation, but being able to include individual new aspects, truly personal to the client, demonstrates the capability and craftsmanship offered by Mulliner. Convertible #4 is joining an extensive car collection that includes a Blower Continuation Series, a Speed Six Continuation Series, and the first of the modern-era coachbuilt Bentleys, a Bacalar.
Sonia Breslow comments, “As long as I can remember, I’ve been passionate about cars. When I have a car like this, Batur, I don’t plan on selling it in my lifetime—it’s my forever car. I’m totally into the detail, and I love designing them—picking out the colours, working through every shade, every feature, and making them different from everything else.”

Batur Convertible #4 features a specification that leans towards a luxury aesthetic, utilizing the client’s own commissioned colours in a tri-tone design, including a 6 mm gloss-silver fine line that emphasizes the Batur’s ‘endless bonnet’ design. The upper colour of ‘Breslow Blue’ has been color-matched for the roof canvas, delivering the first bespoke colored roof, which, when stowed, reveals the matching airbridge in the same exquisite colour. Exterior detailing continues with a ‘Midnight Breslow Blue’ bonnet pinstripe matching the lower exterior paint, accent colours to the wheels and wing mirrors, and polished titanium exhaust finishers and bright silver grilles.
For the client, it’s the tasteful personal touches that make her car collection uniquely identifiable. When entering the cabin, the animated welcome lamp projects a handwritten script of her name via 415,800 microscopic mirrors, sculpting the shape of the light to produce one of the most personalized features in the car.

In harmonious contrast, the interior of the cabin combines warm autumnal colors—tans, caramel hues, and the familiar light blue accent color—drawing the unique bespoke Breslow Blue of the airbridge directly into the cabin. Contrast stitching on the tonneau continues throughout the interior, extending to the seats, headrest, and instrument panel. Even the contours of the Batur volcano (the origin of the car’s name) outline can be found subtly crafted into the deep-pile floor mats.
Taking inspiration from early Bentleys, a bright aluminium engine spin finish completes the cabin fascia. The Bentley Rotating Display includes bespoke coloured faces for the three gauges and matches the satin blue Bentley clock face. The engine spin fascia is not the only crafted metal feature in the cabin; adding to the artistry, Batur Convertible #4 debuts Bentley’s first application of three-dimensional printed platinum. The top-dead-center marker on the steering wheel and each organ stop are crafted in this precious metal, underscoring the car’s exclusivity and innovation.
Despite its highly bespoke nature, the Batur Convertible retains the most powerful iteration of Bentley’s iconic W12 engine: a 740 bhp, hand‑assembled 6.0-litre twin‑turbocharged powertrain, ensuring a grand touring experience worthy of Mulliner’s flagship coachbuilt series.
The final specification of Batur Convertible #4 is a masterclass in collaboration—powerful, elegant, and soon to join the owner’s other Mulliner siblings.
