History of the Austin Kimberley and Tasman
These cars were offered as an Australian replacement for the Austin 1800. Their boxy styling, developed for the car to be a proper six-seater, was all new, though a few features, including the doors, were kept; the doors used recessed handles to satisfy Australian Design Rules safety concerns. The body had exceptionally stiff torsional rigidity, a trait it inherited from the 1800s.

At the time of the X6’s launch on the Australian market it was quite an advanced design in comparison with the competitors from Ford, Holden and Chrysler, whose rear-wheel-drive, conventionally sprung underpinnings dominated the market.
Engine
The standard powerplant was a transverse-mounted 2.2 L OHC straight-six based on the 1500/1750 Austin Maxi unit; at its introduction it was the only car in production with a transverse straight-six engine. The Tasman’s single carburettor gave 76 kW (102 hp) and the Kimberley, with its extra carburettor, 86 kW (115 hp). Both were sold with either a four-speed manual or a three-speed automatic. The engine would also be used in the ADO17 Austin 2200, Morris 2200 and Wolseley Six, and later in the ADO71 Princess; in Australia, enlarged to 2.6 litres, it also appeared in the Morris Marina and Leyland P76, mounted longitudinally.
Kimberley and Tasman
The differences between the two were generally in trim: the Kimberley was the upmarket model, with a plush interior and four rectangular headlights, while the Tasman had basic vinyl trim and a simplified grille with two round headlights.
