Yes, in the context of Australian and British English, a prime mover can be considered a type of lorry. The term 'lorry' is often used to describe a large, heavy motor vehicle designed for transporting cargo, which encompasses the functionality of a prime mover. However, prime movers are specifically engineered for towing trailers and are distinct from rigid lorries, which have a fixed cargo area as part of the main vehicle body.

Fuel consumption for a prime mover varies based on the engine size, load weight, driving conditions, and overall vehicle efficiency. On average, a prime mover may consume between 20 to 60 litres (approximately 5.3 to 15.9 gallons) of diesel fuel per operation hour, with variations observed during long-haul trips, idling, or when navigating challenging terrains. Modern prime movers equipped with fuel-efficient engines and technologies can achieve better fuel economy, particularly when maintained properly and operated under optimal conditions.

The towing capacity of a prime mover depends on its design, engine power and the specific regulations in place. In Australia, prime movers can typically pull loads ranging from 40 to 200 tonnes, with standard configurations usually rated for up to 70 tonnes. Special permits and configurations, such as road trains, allow for higher weight limits under certain conditions and in designated areas, enabling the transport of substantial loads over long distances in rural and outback regions. Compliance with national and state regulations is essential to ensure the safe and legal operation of prime movers at these capacities.
