Meet Batur Convertible #4, a Mulliner coachbuilt Bentley shaped not by a committee but by a conversation. The client, collector Sonia Breslow, has already commissioned a Blower Continuation, a Speed Six Continuation and a Bacalar. Her latest is the most highly curated Batur to date, and it turns four firsts into a manifesto for ultra‑personal luxury.
Bentley calls it a tri tone. In practice, it is a meticulously layered composition that starts with Breslow Blue up top, dips darker to Midnight Breslow Blue below, and is tied visually by a 6 mm gloss silver fine line that traces the car’s long, “endless bonnet.” The roof canvas is colour-matched to the body, another first, so top-up form and top-down profile speak the same language. There are accents where it matters and restraint where it counts: bright silver grilles, polished titanium exhaust finishers, wheel and mirror highlights that pick up the darker shade. It feels considered rather than loud, like a tailored suit with a single sharp pinstripe.
Inside, the palette warms to tans and caramels, lifted by the familiar light blue that pulls the Breslow Blue Airbridge into the cabin. The stitching flows from the tonneau through the seats and headrests to the instrument panel, which keeps the eye moving without shouting for attention. The deep-pile mats hide an outline of the Batur volcano if you know where to look. The engine-turned aluminium fascia catches sunlight in tight, period-correct spirals, while the Rotating Display wears bespoke gauge faces and a satin blue clock that quietly telegraphs the theme.
Then the jewellery: Bentley’s first use of 3D printed platinum, placed on the steering wheel’s top dead centre marker and each organ stop. It is tactile, cool and perhaps a little decadent. If that is the point of coachbuilt, it succeeds. Less subtle is the animated welcome lamp that projects the owner’s handwritten signature using 415,800 microscopic mirrors. It proves the digital craftsmanship Mulliner now offers alongside leather and metal.
The Batur Convertible keeps the brand’s most potent W12 alive for a little longer. A 6.0 litre twin turbo, hand assembled and good for 740 bhp. It reads like a farewell aria in a company planning to go fully electric by 2035. In a grand tourer like this, power is about composure as much as speed. Expect tidal torque, long-legged refinement and the peculiar calm that only a big twelve can deliver. The powertrain defines the car’s character more than any stopwatch number ever could.
Coachbuilt Bentleys caters to society’s few. Mulliner’s modern take revives that intimacy with technology as the enabler. Co-creation is not a buzzword here. It is why this car exists with a tri tone devised from the owner’s colours, a roof that matches precisely, a signature that greets you, and precious metal you can touch. This is where the luxury market is heading: pieces that read like a personal archive rather than a specification sheet.
There is a tension, of course. The Batur celebrates artisanal combustion at a time when the brand’s future is electric. That contrast is not a contradiction so much as a snapshot. For collectors, a coachbuilt W12 convertible in 2026 is both transport and time capsule.
Batur Convertible #4 is not about horsepower wars or lap times. It is about memory, touch and the satisfaction of getting every detail to sing in harmony. The signature lamp will spark debate. The platinum organ stops will raise eyebrows. Good. Polarisation is part of personality.
If you believe the highest luxury is choice, curated with discipline, this Batur is a compelling argument.
