History of the Austin Loadstar
The Loadstar was offered in the UK, Australia, New Zealand and Scandinavia, partly again as the Austin K2 for the 2-tonne and as the Austin K4 for the 5-tonne payload variant. In the early 1950s economic difficulties forced Austin and Morris to merge to form BMC; as a result the Loadstar was replaced in 1956 by the Austin S201/401/501, which was also offered as the Morris WF through badge engineering.

K-series engine
The Loadstar was powered by Austin’s 3,995 cc K-series six-cylinder petrol engine, known for its durability and also used in other Austin commercial vehicles and passenger cars of the era, including the A125 Sheerline and A135 Princess. No diesel was initially offered; a Perkins P6 diesel became available later in production for operators seeking better fuel economy.
K9 variant
A military 4×4 variant known as the K9 was also produced and used as an ambulance, water carrier, recovery vehicle and radio lorry. The military version often had a round hatch in the cab roof for defensive and observation purposes.
