The $1.6 Million Australian Coupe Built for the Driven
Hand-built in Melbourne and limited to just 10 cars a year, the Zeigler/Bailey Z/B 4.4 is reshaping what a modern collector car can be.

In a quiet workshop in inner city Melbourne, one of the most ambitious performance cars in Australia is being built by hand.
Limited to just 10 cars a year and priced at $1.6 million, the Zeigler/Bailey Z/B 4.4 is not designed to chase mass appeal.
It is built for a very specific kind of driver. One who wants feel over flash, engineering over hype, and a car with soul as well as speed.
The Z/B 4.4 takes visual cues from the classic air-cooled Porsche era of the late 1970s and 80s, but beneath the familiar silhouette sits an entirely new platform.
Rather than restoring or lightly modifying an old chassis, the team has replaced the floor and structure with a clean-sheet, motorsport-bred tub, engineered to modern Australian safety standards and designed to work in both right- and left-hand drive.
The result is a car that looks nostalgic, but behaves like a thoroughly modern performance machine.
Power comes from a bespoke 4.4-litre air-cooled flat-six engine, designed and assembled in-house and machined from solid aluminium billet.
With 300 kilowatts of power and 500 Newton-metres of torque, its output slightly surpasses that of today’s Porsche 911 Carrera, while retaining the raw sound and character of classic air-cooled engineering.
Much of the car’s suspension architecture is inspired by Le Mans prototype racing, with push-rod actuated dampers and a multi-link rear system designed to deliver both comfort and precision.
The electronics have also been built from scratch, using a solid-state CAN-bus architecture that allows for digital instrumentation, remote diagnostics and ongoing software updates.
Every Z/B 4.4 begins life as a donor Porsche 911 from the 1975 to 1989 G-series era. From there, almost everything mechanical, structural and electronic is reimagined. More than 3,500 bespoke parts go into each finished car.
Despite the engineering depth, this is not a track-only machine.
Owners are involved in the personalisation of colour, trim and finishes, with many choosing to take part in selected phases of the build itself. Seating, ride settings, digital displays and even engine tuning can all be adjusted to suit the driver.
Behind the project are entrepreneur and Porsche collector John Zeigler Jr and automotive engineer Greg Bailey.
Together, they have created not just a car, but a global low-volume manufacturing model, using advanced CNC machining and 3D printing to produce parts that would once have been impossible to fabricate locally.
The business now employs a specialised team of designers, engineers and assemblers, and has plans to scale internationally through engines, components and licensed assembly.
For collectors, the appeal is as much about rarity as performance. Only 10 cars a year will be built for the Australian market. Six are already sold. Delivery from order is about 12 months.
In a world where hypercars increasingly blur into one another, the Z/B 4.4 stands apart as something deeply personal and proudly Australian. It is not designed to dominate social media feeds or sit under velvet ropes. It is designed to be driven.
As the creators like to say, you do not buy cool. You build it.

Four one-off Cullinan commissions draw on the design language of yachting, blending marine craftsmanship with Rolls-Royce’s signature bespoke detailing.

Rolls-Royce has revealed a new series of bespoke Cullinan motor cars inspired by the world of yachting, with four individually commissioned vehicles reflecting the materials, movement and design codes of life at sea.
Presented at Goodwood in the UK, the Cullinan Yachting collection comprises four one-off vehicles themed around the cardinal directions, North, South, East and West, each expressed through distinct exterior finishes and interior detailing.
The commissions lean heavily into maritime influence, a space Rolls-Royce says is closely aligned with its global client base.
Each vehicle features marine-grade teak, hand-painted fascia artwork inspired by the wake of a tender cutting through water, and intricate marquetry compass motifs made from more than 40 individual pieces of wood veneer.
Hand-painted elements have become an increasingly sought-after feature among Rolls-Royce clients, with the brand employing dedicated artisans to develop bespoke interior compositions.
For the Cullinan Yachting series, the painted wake effect required months of experimentation to achieve a natural sense of movement.
Inside, the vehicles are finished in Arctic White and Navy Blue leather, with hand-stitched detailing designed to echo the structure of nautical ropework. A signature Rolls-Royce Starlight
Headliner has also been reimagined, with fibre-optic constellations arranged to reflect Mediterranean wind patterns.
Each car’s exterior colour has been developed to align with its directional theme, ranging from lighter blue tones evoking northern waters to deeper hues referencing warmer southern seas and storm-lit horizons.
Rolls-Royce said the collection reflects a longstanding relationship between the marque and the world of yachting, dating back to its co-founder Charles Rolls, whose family owned a steam yacht and travelled extensively through the Mediterranean.
The release underscores the growing demand for highly personalised vehicles among ultra-high-net-worth buyers, with Rolls-Royce increasingly positioning its cars as part of a broader luxury lifestyle that extends beyond the road.
