Australian Capital Territory drivers are using less fuel per 100 kilometres than motorists in other areas, the recently released Bureau of Infrastructure, Transport and Regional Economics report shows
Australian Capital Territory drivers are using less fuel per 100 kilometres compared to other areas, the recently released Bureau of Infrastructure, Transport and Regional Economics (BITRE) report shows.
The Australian Capital Territory has the least fuel-intensive passenger vehicles — averaging 9.7 litres per 100km — due to a higher than average proportion of smaller vehicles with four or less cylinders and late-model vehicles in its vehicle fleet. Outside of Canberra, the most fuel-efficient vehicles are Brisbane CBD, Brisbane West, Sydney CBD, and Sydney’s eastern suburbs. Inner city residents tend to have lower average rates of fuel consumption than middle and outer suburban residents, due to the greater prevalence of small vehicles in inner city areas.
Vehicle type, fuel type, number of cylinders and year of manufacture were all considered as part of the survey, which analysed state and territory registration data from October 2015 to 2016. The report investigates state and territory differences in fuel economy and presents the average rate of fuel consumption for Australia’s regions.
There is minimal variation in the fuel economy of passenger vehicles by state of registration, with the six states and the Northern Territory all having average rates of fuel consumption of between 10 and 11 litres per 100 kilometres.
Unsurprisingly, regional residents drive vehicles that are 0.7 per cent less fuel-efficient, on average, than their urban counterparts, reflecting the greater prevalence of large passenger vehicles with six or more cylinders and older model vehicles in regional Australia.
Average weekly household expenditure on motor vehicle fuel is in fact much higher in rural areas at $65, than it is for the average Australian household at $47. Potential contributors to this higher spend include rural households facing higher fuel prices and usually travelling greater distances than people in the city.
Based on the 2016 Census of Motor Vehicles, petrol vehicles comprise about 87 per cent of the stock of passenger vehicles, compared to 11 per cent for diesel vehicles and two per cent for LPG or hybrid vehicles.
Australia’s diesel vehicle fleet is relatively new, with 52 per cent of diesel vehicles manufactured in 2011 or after, compared to 29 per cent of petrol vehicles. While post2000-model diesel vehicles tend to be more fuel efficient than post2000-model petrol vehicles, for older passenger vehicles, average rates of fuel consumption are significantly higher for diesel vehicles than for petrol vehicles (12.2 litres per 100km versus 10.9 litres per 100km).
At the time of the 2016 Census of Motor Vehicles, about 20 per cent of passenger vehicles were manufactured in 2000 or earlier, while 49 per cent were manufactured between 2001 and 2010, and 31 per cent were manufactured during or after 2011.
It was expected that a more urbanised jurisdiction with a higher proportion of travel within cities would have higher rates of fuel consumption due to more stop-start driving. However, the ACT is the most urbanised jurisdiction and has the highest proportion of kilometres driven within the capital city (73 per cent), but has the lowest average rate of fuel consumption for passenger vehicles (9.7 litres per 100km).
Western Australia also has a high proportion of km driven within the capital city (71 per cent), but it has a slightly above-average rate of fuel consumption for passenger vehicles at 10.7 litres per 100km.
People in Canberra spend just over $200 a week on owning and operating their vehicles and more than motorists in any other state or territory, but Melburnians are also spending more than $160 a week on average.
