There comes a point in a collector’s life when acquiring what already exists no longer satisfies. At this level of ultra-luxury, the question is no longer availability, but the complete manifestation of personal taste. In the workshops of Bentley Mulliner in Crewe, such a project reached completion in January 2026: the Batur Convertible #4. It represents a rare symbiosis between the marque’s heritage and the deeply personal vision of collector Sonia Breslow.
Breslow, whose garage already houses historic Continuation models and the radical Bacalar, approaches automobile creation with the eye of a curator. Her “Forever Car,” as she calls the Batur, resists the accelerated cycles of the automotive market. It is conceived as a design for eternity, where engineering becomes the canvas for a profound aesthetic exploration.
The visual experience begins with a tri-colour composition that refracts light across the bodywork in entirely new ways. A silver line, just six millimetres fine, runs along the flanks, accentuating the almost aristocratic length of the bonnet. This devotion to detail extends to the roof itself. For the first time, the fabric of the convertible top has been chemically calibrated to match the bespoke “Breslow Blue” paintwork — an exclusive shade that reveals its full brilliance when the roof is lowered and flows seamlessly into the identically coloured airbridge.
Yet the true depth of this co-creation reveals itself in moments of interaction. When the doors open, hundreds of thousands of micro-mirrors project the owner’s handwritten name onto the pavement — a luminous digital signature. Inside, technical coolness gives way to an almost autumnal warmth. Caramel tones and earthy hues define the interior, while the contours of Mount Batur are subtly woven into the deep-pile carpets.
The most radical departure from conventional craftsmanship, however, appears in the control elements. Bentley employs 3D-printed platinum here for the first time. Using this precious metal for the organ stops and the steering wheel marker represents a quiet triumph of innovation over standardisation. It creates a tactile experience underscored by the mechanical growl of the legendary W12 engine. Delivering 740 horsepower, this powertrain forms the formidable foundation of a car that refuses to exist merely as an object of utility. The Batur #4 stands as a masterclass in collaboration — elegant, effortless, and proof that true excellence requires both time and a clear, confident voice.
