The latest Batur Convertible has been completed by Bentley’s Mulliner division. Batur Convertible #4 joins the owner’s existing collection, which includes a Blower Continuation Series, a Speed Six Continuation Series, and a Bacalar.

The client, Sonia Breslow, specifies every detail of her cars, focusing on cohesion across colours and materials. Adding personal touches shows the skill and craftsmanship of Mulliner.

Sonia Breslow says, “I’ve always loved cars. This Batur is my forever car. I enjoy designing every detail choosing colours, shades, and features to make it unique.”

Batur Convertible #4 uses the client’s commissioned colours in a tri-tone design, including a silver line highlighting the long bonnet. The roof canvas is colour-matched to ‘Breslow Blue,’ creating the first bespoke coloured roof, which, when stowed, reveals a matching Airbridge. Other details include a bonnet pinstripe matching the lower paint, accented wheels and mirrors, and polished titanium exhausts with silver grilles.

Inside, the welcome lamp projects her name using 415,800 tiny mirrors. The cabin uses warm colours—tans, caramel, and light blue—bringing Breslow Blue from the Airbridge inside. Contrast stitching appears on the seats, headrest, instrument panel, and tonneau, while the Batur volcano shape is subtly crafted into the floor mats.

Early Bentleys inspired the aluminium engine spin finish on the cabin fascia. The Bentley Rotating Display has bespoke gauge faces matching the blue clock face. Batur Convertible #4 also introduces three-dimensional printed platinum on the steering wheel and organ stops, highlighting exclusivity.

The car keeps Bentley’s W12 engine: a 740 bhp, hand‑assembled 6.0‑litre twin-turbo, delivering a high-performance grand touring experience.

Batur Convertible #4 reflects careful collaboration powerful, elegant, and ready to join the owner’s other Mulliner cars.
