The standard powerplant for the X6 range was a transverse mounted 2.2L OHC straight-six engine,[5] based on the 1500/1750 Austin Maxi unit.

The surviving black work hack was offered for private sale in Melbourne in 1990, at which time it was no longer roadworthy or registered.

[8] In the marketplace, the cars were intended as competitors to the more established larger Holden Kingswood, Ford Falcon and Chrysler Valiant models.

However, the complexities of front-wheel-drive were an issue against the car, and compounded with the lack of body variations and models, the X6 was never a serious threat to the dominance of the rear-wheel-drive and multiple-body Holdens, Fords and Chryslers.

One advertisement for the New Zealand specification Morris Tasman X6 proclaimed that the bench seats could hold the driver and seven schoolboy rugby players.

[citation needed] Whilst this may seem an exaggerated claim by its makers, the 1800/Kimberley platform did provide excellent passenger room for a vehicle of such a compact outer dimensions, a legacy of Sir Alec Issigonis who strived for increased cabin space on a small footprint as witness the Mini, 1100, 1800 and Maxi.
