Eco (Australia) - AllCarIndex

Eco Motors Co. Ltd was an Australian automobile manufacturer based in Melbourne, Victoria, that operated from 1924 to 1926. The company was founded by George Hamilton-Grapes, a New Zealand native who had previously been involved in the motor trade. His interest in fuel efficiency led him to develop a patented device known as the 'Gasifier' by 1919, which aimed to enhance the performance of vehicles.

In 1921, Hamilton-Grapes traveled to the United States to construct a prototype of his envisioned car. The Eco vehicle incorporated several innovative features, including extensive use of aluminum to reduce weight, concealed spare wheel storage, and a unique front suspension system. Additionally, it featured heat-dissipating aluminum wheels and a distinctive aluminum collar around the radiator designed to improve airflow.

Production of the Eco car commenced in 1924 at a facility in Oakleigh, utilizing components sourced from the United States. The vehicle was powered by a 3180cc 40bhp Lycoming four-cylinder engine and included a Borg & Beck clutch, Gemmer steering, and Stewart-Warner instruments. The Eco car had a wheelbase of 111 inches (2820 mm) and weighed approximately 1145 kg. The name "Eco" was derived from the term "guaranteed economy," reflecting its ability to operate on kerosene, further emphasizing its focus on fuel efficiency. Despite its innovative design, Eco Motors ceased operations in 1926.
