If you have a lazy $1.6 million kicking around and want something very exclusive of the automotive persuasion, the Zeigler/Bailey Z/B 4.4 might be the answer.
Based on the classic Porsche 911 ‘G-series’ models of 1975-89, the Z/B 4.4 is the brainchild of creators, Porsche collector John Zeigler Jr and automotive and mechatronics engineer Greg Bailey, and is designed and assembled in Melbourne.
The Z/B 4.4 introduces an unprecedented level of substitution of its platform, components and systems, combining the retro silhouette of the Porsche G-series with advanced engineering, but delivering unprecedented analogue driving engagement, from its manual transmission through to its unique, aluminium-billet 4.4-litre air-cooled engine and distinctive styling.
Created for global markets, the Zeigler/ Bailey Z/B 4.4’s platform enables the assembly of both right-and left-hand drive versions, with a retrospective conversion completed in less than eight hours.

Currently six of the annual production run of 10 are pre-sold and are currently in various stages of production. Three cars are already at or near completion, with a further three of the highly modified body shells now ready for internal fit-out. Delivery time is approximately 12 months.
Zeigler and Bailey point out their car is not a ‘restomod’, but a unique Australian design with up-to-the minute platform, engine, suspension, electronics and driver ergonomics, clothed in classic Porsche cool. It has been designed and built to applicable Australian Design Rules.
Powering the 1325 kg (kerb weight) Z/B 4.4 is an Australian, 4.4-litre aluminium billet, air-cooled six-cylinder engine, putting out a claimed 300kW and torque of 500Nm.
With its unique, symmetrical architecture, the suspension is derived from a Le Mans prototype, featuring multi-link, push-rod rear suspension and MacPherson struts up front.
Many of the body panels are made of carbon fibre with the doors and boot lid remaining steel for ADR compliance.
While it visually resembles one of Porsche’s most revered air-cooled models, the 911 RS 2.7 of the early 1970s, and is based on the easily attainable 911 G-series cars from 1975- 89, the Z/B 4.4 exceeds the current restomod engineering, which typically builds on to a dated platform of structural integrity, suspension geometry and driver positioning.
The ‘think again’ philosophy of Zeigler/Bailey led engineer Greg Bailey to start again with a new sheet-steel platform for the car, with unique geometries and components befitting a modern supercar.
For the driver, that means an uncompromised seating position and alignment of controls, enhanced by the first height- and reach-adjustable steering wheel to be fitted in a car of this type.
Zeigler and Bailey see the Z/B 4.4 as a global car, bought, sold or potentially assembled under licence in overseas markets.
